QNAP NAS TS-210 TURBO

2010-08-28T22:04:00.002+07:00

Here is a fourth, namely from QNAP, the QNAP TS-210 Turbo NAS. If seen from the form of its product, which is owned impressed simple design, still the same as most home-based NAS for SOHO nd. External features on offer is also limited, like One touch copy button (1) and a variety of LEDs that represent their respective functions (2) you may encounter with the front, besides of course the power button (3). At the rear, you'll find the standard diameter fan (4), two USB ports (5), and port RJ-45 (6), which already supports Giga LAN.

This product is on strengthening the integrated processor with a clock of 800 MHz and DDR2 RAM at 256 MB. Of course, this becomes the value of rest. Even when we melekukan testing, the results are remarkable in our opinion. Both in terms of performance, overall assessment and comparison of the performance / price. This product exceeds other products. So it is not wrong, if we are pinning the award logo as well as to three of these products, namely Best Product, Best Buy, and Best Performance.

Although there is still a little imperfection on these products, such as hard disk installation process somewhat complicated and product prices are quite expensive because it is not included with his hard drive. Namum, still we say congratulations on the success!

JUST CAUSE 2

2010-08-28T21:46:00.003+07:00

Entering the second sequel to Just Cause 2 still tells the football lunge Rico Rodriguez, an agent from sheep to American intelligence field, The Agency. Rico this time assigned to an archipelagic state in southeast asia named Panau. His job was to find Tom Sheldon, friend and teacher who was reported missing. But in pencarianya in Panau, Rico actually required to create chaos for the sake of dropping yag dictatorship regime in power. For this purpose, Rico must be willing to work with three criminal groups there.

The meaning seems to create chaos explicitly defined by the Avalanche as a ruin. This is at least drawn from a very large portion of the blasting various objects in many ways. Diledakan Whatever, this game mengambarkannya quite spectacular.

However, the most interesting side of the Just Cause 2 is perhaps the State picture Panau. Exotic environment out here really explored. With beautiful graphics quality, Panau Island as if made to pamper the eyes. Moreover, with the ability Rico in this game has a unique weapon in the form of grappling hook and a special parachute. With both these objects, Rico is able to swing antargedung or even jump from a high cliff without falling and killing is concerned. Grapling his hook can also be used as a weapon, to mejerat opponent and drag him to the vehicle or just a passing helicopter ride!

Rico actions that outsiders can be, supported also by non-linear gameplay ynag. In this game, you could complete the mission in ways that could occur to you. Avalanche Studios is giving a lot of freedom role in Just Cause 2. For example, the game is said to have no fewer than a hundred that could be used kendaranan Rico. Not to mention the existence of various weapons. Unfortunately, this game also has some weaknesses. Application of check points that rather rarely makes the mission difficult to get more difficult and potentially frustrating. However, the main weakness of this game is he does not support Windows XP. Or perhaps it is precisely the right time to switch to Windows Vista or even Windows 7 ?

2D ADVANCED JAVA GAME PROGRAMMING

2010-08-28T21:23:00.005+07:00

This article is a continuation of the two articles on making Java game before. In this article, the author will discuss more about the concept of game programming using java.

Lots of interesting articles that are published on the website forum develover games like www.gamedev.net or www.javagaming.org. start from the basic game programming concepts to complex programming sebenarnyamalah porses simplify manufacture. Indeed, in programming, not only in games programming, design becomes the main foundation for making process does not come out of the main objectives. You can choose whichever method of suitable design for you. However, in this article the author would not discuss the issue. We return to the basic concepts of programming in java gaming.

After learning how to use java to make a simple 2D game, this time the author will present advanced concepts for a game. To further simplify, the author uses source code that has been made in the previous article, which can also be downloaded on the blog writer, http "/ / www.fauzihaqqi.net.

Sprite

Part that almost always there in a game is a sprite. The word sprite has multiple meanings in game programming. which means that there is a set of sprite images or animations that united in a larger gambaryang. Others say that the sprite is a term used to encapsulate a character in the game. a more general, and the sprite is defined as any object that has the location, pictures, and usually can be moved.

But in this article, sprite more emphasis on the encapsulation of an object in the game, whether the object moves or tidak.Bahkan itudapat a button "New Game" in the game menu could also be considered as a sprite, jikamemangmemiliki location and other attributes.

Try to think back a bit, what are the objects that must be defined in your game. A simple example of this snake game, there must be at least gamepanel for game area, snake to the representation of a snake, and apple to apple representation.

Gamepanel and snake we've created in the previous article. The rest, you just create a sprite apple that will form the food of the snake.

Simple, right? which pperlu you do just think in a structured starting from scratch. sprite design whatever is needed for your game. attributes and capabilities needed any sprite. Like for example, the snake must have the ability to migrate. different from the apple that exist only in one place for every apple-nya.Yang need to really think about is all the things that concerns only the sprites, the sprite must be done by itself. One example is the rendering. Each sprite should be able to draw himself, although nantinaymemakai Graphics2D object from its container. This is in accordance with OOP programming concept that is suitable for making games.

Collision Detection

The next basic thing in programming games is a collision detection (collision). The definition of collision here is not what happens if there is an accident. But the collision detection here is how to determine if an object is being cut (intercept) of other objects in the game.

There are many techniques and algorithms to detect whether the collision occurred or not. This collision is most easily detect if your game bettipe tile-based. Thus, all you have to do is check every tile of your game. The most serious incident, you should check that in fact the whole tile is smaller in number than the pixel size of these games. Thus, the computer will not take too long to detect it.

Unlike pixel-based collision detection him, indeed our eyes can easily detect whether an object is star-shaped star collided with another at the end. But it's not easy enough for a computer. If the algorithm you use is not efficient then the computer will be forced to check the entire pixel, until finally discovered that the collision occurred. this can reduce the performance of your artificial game.

In the example in the previous article, there is no collision detection between the snake with the edge of the area gamepanel. So if the snake up on the edge, he'll keep walking and disappear into the area outside the range. This should not be terjadi.Karena this snake game is a tile-based games. You only need to check whether the head of the snake out of the arena. Collision detection should be carried out section that holds the second largest object to be detected. In this case, means you have to detect it on gamepanel.

Sample source code simple. You can add the method below to the class Gamepanel:
... ...
not only the collision between a snake with the edge of the arena, but need also captured whether a snake's head was hit the apple, which means that the snake has eaten. You simply add a simple line below:
... ....
CreateNewApple method () will create a new apple somewhere random. While the method addBody () on the snake will add a body length of the snake. It will not be described in detail in this article, but you can learn more at an existing full souce code diblog author.
For the class first person shooter games like Counter Strike has been using collision detection based on pixel. It is not easy to do, especially for three-dimensional game. Slah one simple way is to define the boundary (boundaries) of the object to be in check. So, they only need to check each object edge pixel. Then, how to detect the edge of the object with the program? That is your challenge as a programmer.

Background

Background (background), including things that are important in game development. A good background will be able to define trembling well too. There is background only serves as a complement to, but there is also a character as an object of the game. There is a static background, there also may be engaged.

An interesting trick that gives the impression that kerakter move is by moving the background. You may see the classic Mario Bros. game. When Mario runs, Mario is not really moving on the screen, but the background is moving against the direction, so it would seem that directly mariolah're moving forward.

In rendering the concept, background is the first object to be rendered on the screen. It was clear that the goal is to not cover the background characters that will direndersesudahnya.
In tile-based games like Final Fantasy Tactic, Romance of the Three Kingdom, as well as the usual game two dimension of this snake, the background is not included in the large size, but dipecahmenjadi small sizes. Then the loop will be done to render background images.

Typically, image files and the file mapping information terletakterpisah background. It is intended to avoid redundancy between the image file that stu tile with another tile if you use the same file. Enough background mapping information stored in the form of text to index every file of the drawing.

However, there is also a background that is stored in large sizes, usually only once or indeed digunakn unnecessary surgery on the background. Typically, this type of background articles used to make the game start menu.

Background in the example source code consists of a writer only fil; e image size 10 x 10 pixels which will render the loop so that all plots have the same background.

State Game

Situation (state) of the game must be kept properly. The most simple things of this state is whether the game is running, pause it or are already game over. This is very influential on the game you made. Render the information in the game will also vary depending on the state's happening. For example, when you play Warcraft, if the tone of pressing the F10, by default the game will stop (pause), and the menu will be displayed.

Another example of state that is your destination information that are superior players at that time. For example in fighthing game, win-lose position each player is also stored.
Game state can be global or local according to each object. One example of a global state is a condition in Game Counter-Strike game, how many times terrorists win and how often do Counter Terrorist win. While the example is whether a local state of each player is still alive or already dead shot.

In the example source code provided by the author, can be seen that the state is still simple. State of the game was whether the game is running, pause it or game over. This is so that you can further explore to make the state-state ynag more detail again.

For any game over, the only way the game was when the snake struck his own body. In the game you made, you can add sprites form of a wall that will make the snake die if hit.
To put the interception that state, you can change the thread a little structure on the source code for the previous article, to be like this:
... ....
As is known, to declare a global variable in java, you can use the keyword "static". The aim is that these variables can be accessed by any object, without the need to contruct an object that has the variable. While the konstansta to declare, you can use the keyword "static final" variable so that it can not be modified, but can be accessed by any objeck.

To display information on whether the game is in the running position, pause it or game over, you simply add a few lines on the method paintComponent () senjadi as below:
... ... ..
Thus, updating a snake and collision detection is only done when the game is running. Depictions of information "Paused" or "Game Over" hanay happen, if the state is in progress in accordance with the conditions.

Do not forget to set the keyboard keys used to intercept the event pause. In contoj writer, the game will be paused or running if the player hit the Enter key. You simply turn it on in Game KeyAdapter Panel:
... ...
You can add a simple form of value-state players, that is what apple has been eaten by siular ynag, then displayed on the screen. You simply create a new variabelstatic and add value to it when there is a collision between the head of the snake with an apple.
Note: The author uses Windows 7 and JDK6u17untuk run source code. In the skin of Windows 7 have a nonconformity that causes packing java components leave little blank area and right edge of the section under the window, as shown.

Easier to Game Engine

The main skill a programmer is to copy-paste. When the programmer wants to create a game with a new idea, but with the same structure. Will generally be open long program code, then copy-paste the line that can be used again. If using this method, at least all the lines that became the basic functions of the game to be moved. Imagine, if you haruh carefully sorting lines which can be used again and which ones have to be rewritten, what more if you create a program with a structure that is less tidy. If it is so, like sodium absorption ratio would force spearheading ynag matalah. All the concepts and basic game programming that has been submitted, the author usually has been there in a game engine.

Game Engine is a software that is designed and articles used for the manufacture and development of a good engine game.Game should at least be able to menghendle citation needed-these basic operations. In fact, the existing game engine that provides basic AI (Artificial intelligence), a basic artificial intelligence such as the shortest route search and so forth.
The background of this game engine is very heavy because they to make a game from scratch. Because you have to make all the basic things, like how to display an animation, how to make sound effects and how to detect collisions. Though the process is usually almost the same in all games.

Thus, they invented a library that includes all the basic game development so that these libraries can be reused by programmers all want to make a new game, without starting from scratch. Or in other words is a copy-paste and unloading pairs.

Any type of game engine range. Some only provide the basic components, there are already providing a special class game with a certain genre, and even have a GUI that exists at making games look pretty doing drag and drop only.

Here is a list of Java game engine that you could try, and its official Web site address:
• A Menkey Engine (www.jmonkey-engine.com)
• Golden T Game Engine (www.goldenstudios.od.id) - game engine made in Indonesia
• JGame (www.13thmonkey.org/ ~ Boris / igame /)
• Slick (http://slick.cokeandcode.com/).
• LWJGL (http://www.lwjgl.org/).

Every game engine has its own cirikhas and methods. Game engines are also different levels, there are only providing basic methods, there ynag two-dimensional and there is even a three-dimensional. All of the above game engine is open source. You just try it, and choose which is appropriate for you. Deepen your skills with a selected game engine.

If you want to and intend to dive in the world of game programming, you'll want to make the game engine itself. This game engine that you use as needed, nothing less and nothing more. Learn how the concept of the structure of an existing game engine, how the active process of rendering it, how the main methods. For convenience, look for open source game engine with the same language, then copy-paste the code you need. However, do not forget to continue to respect the source code license.

Welcome to make games.

Reserving With OllyDbg

2010-08-28T21:02:00.003+07:00

PART 1 OF 2 ARTICLES

Like a time machine, reversing the process of trying to uncover what lies behind the creation of a program.

We get an application form of executable files, meaning you telahmendapatkan result of work of an individual or a team of developers, who build the applications from a series of codes program.Dengan just run the application, you will find it hard to know with accuracy and detail, about what actually serve targeted applications. Except if you have the source code before compiling the application on, or do the reverse code engineering (RCE).

Low Level Software

Computers and software layer built from different layers. Akstrem comparison is to look at the outer layer, ie graphical display desktop pad, while the innermost layer is the millions of transistors on the CPU. on programming languages, is the lowest level assembly language. Opersasi anything done a software can be seen in assembly code. To understand the RCE with a good, low-level must be understood first.

Therefore, we will look at the process from the lowest level, when an executable file is run. CPU will work with membacasekumpulan bit contains a set of instructions. This form of machine code instructions (machine code, or often called a binary code), which you can see when you open the file in a HEX editor.

Assembly language represents a collection of bits in the form of human readable text. so, rather than seeing a row of hexadecimal digits, it would be easier for you to read the text instructions such as MOV (Move), XCHG (Exchange), and so on.

Reversing

RCE general understanding is a process on an object to know deconstruction details. In connection with computer software, reverse engineering software mendekontruksi, it returns to the analysis process by:

1. Analisismelalui observation of exchange of information, such as taking the data traffic on a computer network tertentu.pengamatan generated by the software is expected to represent the behavior of software used tersebut.Tool include a bus analyzer or packet sniffers. Generally, this method is used to perform a reversing device drivers on embedded systems.

2. Decompile, by Decompiler. Decompiler attempted reinventing the source code in a high-level programming (eg Visual Basic, FoxPro) from the machine code. The success of decompilation process depends on how much information tekandung in the code that has been compiled, and how well the level of analysis used Decompiler. If there are metadata or debug data on the machine code will simplify the process of decompilation.

3. Through the process of disassembly, using Disassembler tool. That is, translating the machine code into assembly language. Disassembler tool, such as IDA Pro, ILDASM, PVDasm, and that will be the topic of this article, namely OllyDbg.

Pros and cons reversing habisnyakarena probably will not be there always can be seen from two viewpoints. For example, perhaps reversing regarded as a savior if used for purposes of analysis applications suspected of harming a time bomb, but reviled when it was used for the cracking process, such as making modifications to a trial period for paid applications are ignored.

For things that are positive, reversing usability are:

1. Found the malicious code. For example Pasa applications suspected of violating the provisions of the secret code, like a time bomb that could disrupt the company's operational processes.

2. Find the error code. Say an application no longer has the cource code for or in another, but it has a bug that mengganggu.Proses reversing can help find these errors.

3. Find the usefulness of the code. There are certain cases dimanaanda workings require an application in detail, perhaps to understand the logic and flow, which is not obtainable because of the unavailability of source code.

4. Analyze the workings of malware. Several techniques and reversing the damaging effects malwarememerlukan process, so that action can be taken and appropriate response.

OllyDbg

OllyDbg is a tool Disassembler / debugger for windows operating system. its creator is by Yuschuk or known by Olly. OllyDbg is one of the favorite tool of many used by people who wrestled on the http://www.ollydbg.de RCE.Beralamatkan world, until this article was written after reaching version 2.0, written ualng from scratch and does not yet support the use of plugins like the previous version . however, you can still download the old version which has implemented the use of plugins, or you can get the DVD of PC Media edition.

OllyDbg is a shareware, but the author did not request a fee for commercial use or permanent. Simply fill out the registration form and send via e-mail.
Some of the features and usability OllyDbg is:

1. Can recognize the procedure, API calls, and most of the function C.
2. Find Feature Reference for memory and string.
3. Able to debug the DLL file.
4. Every program that is running can be summoned and to debug.
5. And there are many 3rd party plugins (not currently supported by OllyDbg version 2.0).
6. Be updated and patched.

OllyDbg is one of convenience does not require installation. you simply download, unpack, and run it. Example 2.0 OllyDbg display shown in the pictures.

For the first time using OllyDbg and try to open an executable file, it may display a screen that looks pretty "scary". do not worry, note the red numbers (numbers 1 to 8) at each window OllyDbg a picture id. explanation of each window is represented figures are as follows:

1. The first column of the main screen contains the address or offset.
2. This column is the opcode, as shown you're open filemelalui HEX editor. Some symbols may be found at the beginning of the opcode, for example, the symbol ^ (or v) that shows the code jumps to the top or bottom. The jump instruction will be discussed later. , yang menunjukan kode jump ke lokasi spesifik.Kemudian juga ada simbol $, yang mengindikasikan awal function." onmouseover="this.style.backgroundColor='#ebeff9'" onmouseout="this.style.backgroundColor='#fff'">Another symbol is>, which shows the code jumps to the location spesifik.Kemudian there is also the symbol $, which indicates the beginning of function.
3. Text that represents the opcode, instruction-intruksidalam contains assembly language.
4. Is the space to make comments, whether comments are generated by OllyDbg araupun written by users (with a right click, select "add comment ...."). ASCll text referenced by the opcode is also shown in this section.
5. This section shows information about the instructions being to debug. Say if you have come to the command "MOVEBP, ESP" then this section will include content from the EBP and ESP. Also indicates whether a jump condition will be executed or not (jump is taken / jump is not taken).
6. This window shows the register information such as Standard registers, flag registers, segment registers, or registers debug/FPU/MMX/3DNow. The content of this register can be capricious, when you debug the code step by step.
7. ASCII atau Unicode )." onmouseover="this.style.backgroundColor='#ebeff9'" onmouseout="this.style.backgroundColor='#fff'">is an area of memory addresses tertentu.anda dump can change the appearance of this area, such as ASCII text / Unicode (right click on your area, select the text-> ASCII or Unicode). Or even do Disassembler in this area (right click, Disassembler).
8. Is a window that displays information on the stack.

Still, there are several other windows that can be accessed via the toolbar menu (the log window, memory map window, the CPU window, and so on).

For example, Alt + E will open a window executeble modules.
You can also change the values that appear for instance in the window register, the contents of the register can be changed by right-clicking the register value and select Modify (or double-click that value).

Important Shortcut

One of the main functions OllyDbg is a debugger, there are shortcuts to the shortcut that can simplify the job. For those of you who have been accustomed to using high level programming languages such as Visual Basic / Delphi, would also never use the same debugging features.
For debugging or executing code per line in OllyDbg, you can use the shortcut F7 (Step Into), or the F8 (step over), and be careful in debug malware because F9 shortcut will run the application (Run). To restart (start again from the beginning of the program), use the shortcut Ctrl + F2. Another important shortcut to debug is to create or mebghapus F2 breakpoint. You can make more than one breakpoint.

Basic Assembly

Because OllyDbg translate into machine code assembly language then we must understand the basics of assembly language. could even be said, this is the core using OllyDbg.Semakin much you know about the assembly, the easier you memahamiaalur courses that appear on OllyDbg, coupled with features that simplify the process of reversing OllyDbg.

Discusses in detail the assembly language can be a separate topic that is vast, but here given the basic concept that you do not look too upset with OllyDbg. At the assembly, we will banayak associated with the register. Storage registers on the CPU is the fastest access. Example 32-bit registers for general purposes (arithmetic operations, indicates the offset address), among others, are EAX, EBX, ecx. Another example is a segment register (SS) is paired with a stack pointer register (SP). The contents of registers accessible through the assembly instructions, including MOV (Move), PUSH, POP, CMP (Compare), INC (Increase) and so on.

For example, the command MOV EAX, 0 means to fill in the EAX register with a value of 0.
In doing debugging with OllyDbg, you will find a lot of the jump command, used to jump to specific areas of program.Terdapat many orders jump, jump without conditions with JMP apapunditulis followed by a goal, for example:

7C901011 JMP
Each command will be executed JMPyang encountered. There is also a jump command that has the condition, which is assessed through the CMP command, TEST, or other commands. Some examples of the jump command that will evaluate the previous command is JA (Jump if Above), JNE (Jump if Not Equal), JL (Jump if Less), and many lagi.Terlihat complicated? Actually not really because each of these commands has a catchy acronym, namely:

J = Jump
E = Equal
N = Not
S = Sign
Z = Zero
P = Parity
O = Overflow
C = Carry
G = Greater Than
A = Above
L = Less
B = Below

CMP Printah ecx, 0FFFF will compare operand1 and operand2, followed by JBE orders are fulfilled. See the table above are obtained JBE Jump if Below Equal means, or if operand1 <= operand2 (operand1 if below or equal to operand2). Opening and bereksperimendengan some files contohakan make your environment OllyDbg.Pada terbiasabekerja on the next article, will dibahaas more in-depth example of using OllyDbg again.

VIRUS LABORATORY

2010-08-28T20:51:00.003+07:00

Make friends with the virus is fine, but you must bear to deny the relationship even further.

Igin Most people do not connect with computer viruses and no one wants a virus (including virus makers). But some people enjoy work analyzing computer virus, although impressed "intimate" tinkering with the virus, but without adequate preparation laboratory viruses, system and your data can be ravaged by the virus.

Destruction by the virus

Imagine you are researching and experimenting with the virus in the truest sense, ie a biological virus that could transmit the disease, and infected, would have had to put up a secure and isolated environment. Similarly, by examining the computer virus. Do not let the virus spread pda system that you use everyday. Mean heart researching the virus, became victim of a virus! Not infrequently destructive virus data files (documents, images, video) or the system sepertiregistry Windows, executable files, or other important files. So, prepare a special place in the ready to dissect the virus.

While "viral" is a term often used to generalize all types of malware (because the virus is a type of malware that the first well-known and widely spread), as it grows, understanding the virus has actually been different if the reference to other malware such as worms, Trojans, adware and spyware .

Thus, there is a tidaj maleware infected files and replicate themselves. Therefore, apart menamati faster relative impact is known (the emergence of new files for suspicious, look and messaging viruses), also be aware of the impact of no less bad and dangerous, like malware that make the theft of data or take over the system. This looks relatively more difficult and requires in-depth analysis.

Virtual Environment

Creating a virtual invironment to labotatorium virus is an alternative to analyze other virus.Pilihan is preparing a special computer that is dedicated to research, only the necessary resources relatively higher because you have to prepare the hardware (physical machine), installation, and required backupsistem .

While the virtual machine environment, the program is executed as he walked on the actual machine, but actually he is executed on a copy machine with an operating system platform ynag virtually complete, and does not relate directly to the hardware.

This technology allows a computer machine having one or more virtual machine, which runs masig their respective operating systems. Usefulness of the virtual machine is certainly not for virus analysis, depending on needs. IA can be used to test specific operating systems, testing applications on various operating systems, the need for emulation and so on.

Examples of software to create a virtual machine such as VMWare (vmware.com), Windows from Microsoft's Virtual PC or VirtualBox (virualbox.org).

If the virtual machine emulates the operating system and still need time to boot and enter in a virtual operating system environment then we can try another alternative, by creating a virtual environment in a smaller scale, namely by providing a space / space isolated quarantine when running a programs, and emulate the changes that occur. This space can then be removed again and not terjadiperubahan on the actual system.

Malware or suspicious programs can be run in this environment so that its activities can be analyzed, one application for this purpose is Sandboxie (sandboxie.com), which in isolation is able to run applications such as web browsers, online games, instant messenger, executable files suspicious. Mentioned applications are potentially damaging system, if ridden malware.

Like the virtual machine, sandboxie also access the hardware directly. The difference in sandboxie, you still can not exist on real operating systems (non-virtual). Temtu enabled to do to do a double protection, by doing this technique in the sandbox virtual machine.

Language Courses are used

To investigate the virus, would have to recognize or at least, what constitutes suspicious files for viruses. The virus is basically a normal application like any other program, but the form of codes that are meant to perform a destructive operation, capable of spreading as well as defend themselves. So every language pemrogramanyang can access and perform various operations, it can be used to create malware. Some categories are quite popular programming language in the manufacture of virus / malware, among others:

1. Low-level programming language.

Or low-level programming language, which is closer to the hardware instructions, examples are assembly language. In the reserve code engineering, disassembly term known to translates machine language into assembly language. Programs (including viruses) that are written with low-level programming language would be more efficient and faster, than the high-level programming language.

2. Pemrogrman high-level language

Or high-level programming language, which already uses elements of natural language that is more user friendly and hassle of wrapping machines and operations performed (low-level) from the user. In Indonesia is quite commonly found viruses created with Visual Basic (VB most classic version like VB6, not generation. NET), among others, his trademark is to use runtime library MSVBVM60. etc. that are visible on the body of the virus. Visual basic addition, other high level languages that are often articles used to create viruses and other malware is a C / C + +, Delphi. Requires a high level programming language compiler / interpreteryang translates source code into binary form and can be executed.

3. Script host.

Discuss scripting is often used to membuaat virus is a VBScript. How it works can be compared with the batch file, but with more capabilities and features. Because the form of a script and not through the compilation process into a binary file, VB-type virus code can be read with the script contains a virus file in a text editor. But not all viruses can be read easily VBScript. Various techniques applied to the virus more difficult to analyze. Among others, by providing a variable that has no meaning and was impressed at random. Writing the structure of the program code is not neat, or with ASCII characters, such as the character "A" written by Chr (65).

4. Macro Language.

Pemrogrman language is a built-in on a softrware application enabling program code to embed in the document, which unfortunately can be misused to make a virus. The virus produced by a virus called macros. Viruses of this type of pad time to be popular mid-1990s, ynag use macros / scripting language available in Microsoft Office applications, resulting in documents and spreadsheets from Microsoft Word / Exel can be infected.

5. Cross Site Scripting (XSS).

Utilizing vulneriability on web applications that enable an attacker to inject script dilihatoleh web page visitors. XSS exploit code is generally written in HTML and JavaScript, which is executed on the client / web browser. XSS also allow the theft of cookies, even the research shows that XSS attacks can take over the browser, similar seprti Trojan programs.

Therefore, the files can be suspected as the virus is not limited to executable files (PE files), but can be a file.vbs (VBScript), files a document that brings the macro, even a PDF, as well as URL addresses suspicious.

Virus Feed

Virus laboratories can be used to trap viruses to study further action, namely by giving the feed data are often infected or damaged viruses, such as executable files, documents from Microsoft Office files are often used as the target virus (*. doc, *. xls, *. ppt), mp3 audio files, video files and other formats.

Spread via removable disks can also be simulated by installing a removable disk / flash disk and see what's going to be a virus. Be sure not menyompan important and sensitive data on virtual machinemaupun flash disk.

HEX Editor

After you prepare sebuiah a safe environment to analyze and have a sample file that is suspected as a virus, then equip yourself with the right tools. One of them is a HEX editor to examine the body of the virus. The choice is quite a lot, among others, Hex Workshop (http://www.hexworkshop.com), Hex Editor Neo (http://hhdsoftware.com), and so on. If the viral form of scripts, you can see with a regular text editor. Sometimes you can find a specific message in the virus body, or command a certain fuction that can provide clues about the virus characteristics.

PE Analysis

As I've written in the article entitled "Dissecting the PE file" in the 02/2010 issue, PE files have a structured format that can be analyzed, but need to be opened with a tool PE viewer / analyzer, such as PE Insight, PEviewdan many other similar tools. The information is displayed include the contents of the DOS header, section-owned section ynag API and DLL are used. In some cases, the characteristics of the virus began to be read.

File Identification Tool

If only rely HEX Editor / PE viewer, you may find the virus file that did not show a message and a special character which is understandable. Virus body contains only random characters, in this case, you need a tool to identify the file. Why necessary?

From some of the articles discussed ynag reverse engineering code, may Adna have known what was called the packer. Packer was seing digunkan by the virus to wrap himself in which you Juka static virus body dissected, there was only character-karekter meaningless because the original routine virus has a new on-pack and unpack too when executed,
By knowing the packer used by the virus, allowing you to unpack and dissect the body of the actual virus. Packer ynag available and can be downloaded on the internet very much.
Fortunately there are tools that can quickly identify files, among others, is PeiD (http://www.peid.info), which can identify the packer / compiler type used by an executable file. ExeInfoPE (http://www.exeinfo.cjb.net) may also be considered for the same purposes.

Unpack tool

We know a virus uses a specific packer, which you can do next is to unpack. Generally, a packer application also has a built-in feature that you can use to unpack.
For example the UPX packer (http://upx.sourceforge.net), you can simply add the-d parameter on the command UPX command prompt to decompress / unpack the executable files that are packed with UPX. Other tools like Quick unpack, also tried to unpack in general accordance detected OEP.

Debugger / Disassembler

Advanced analysis of where we need to do a disassembly suspected PE files for viruses, which have been shaped assembly code and then analyzed further. Options tool that is used among other things OllyDbg (http://www.ollydbg.de). W32DAsm (http://www.exetools.com/dissemblers.htm) tau IDA pro (http://www.hex-rays.com/idapro)
At this stage, treatment is more accurately analyzed by a virus. Konsekuansinya, this work takes time and knowledge of the low-level, sometimes resulting assembly code requires a long debugging process, especially when translated from executable files created with bahsa pemrogrman ynag high level.

Anti-emulation

The virus continues to innovate in order to protect himself so hard to dianalisisdan disabled. Anti-emulation techniques developed the virus so that virus makers can avoid emulation.
One technique is to run the instructions that are not supported by the emulator so that caused the error exeption and not a virus program running. Viruses can also try accessing the web pages to detect Internet access, and only run if there is internet access rutinvirus. This also causes the virus is not running on a virtual machine / computer that does not have internet access.

Thus could be a laboratory virus we still can not be prepared to analyze Number qf viruses that have certain techniques that particular case, we might need a special computer dedicated to the analysis of the virus arrives.

Cover

Tool that can be prepared in your laboratory is not limited to viruses that have been mentioned in this article.

Various tools with their functions continues to grow (along with a virus which is also developing technologies), although too many tools are also not effective.
Using the right tools pda exact problem is the most ideal way and this is more an art of analysis may be different on each analyzer virus. Ready to build your own virus laboratory?

Security Development Lifecycle

2010-08-28T13:19:00.003+07:00

Microsoft recently released version 5.0 Security Development Lifecycle
What is new and what is offered?

Almost all programmers have to deal with security threats on the application. Many computer users now want every application that is installed has a good security system, without disturbing the user's convenience.

In addition to the security system on the application, the user also wants the implementation of privacy. By Karen was, progrmmmer protect data privacy should be held oelh pemakaui serve targeted applications. To solve the above problem, we can start when the application is made, it means the implementation of secure software development in the drafting process. On the secure software development, there are three important elements that must be considered, namely:

* Best practices
* Process improvement.
* Metric

Implementation of secure software development on the application can digunakn pembutan, among others:
* Business Environment
* Processing personality identifiable Information (PII) or other sensitive information.
* Communicate regularly on the Internet or other network.

Is it the Security Development Lifecycle (SDL)?

Security development lifecycle or in short with SDL is a process of quality assurance on software security that is being created. Microsoft put it in a policy of intensive courses since 2004, which is implemented in all product development dibuat.DEngan combines holistic and practical approach, SDL introduces security and privacy on the entire software development process.

Currently, the implementation of SDL in software development is very important. Based on the targets attacked by the security system shows that the application is the most widely attacked targets ynag security system. Based on the statements of the Microsoft Security Intelligence Report Volume 7 for the interval of time from January to June 2009, showed that many applications were attacked security system and subsequently followed by the browser and OS.

Graph reports can be seen in Figure 1. This report can be downloaded at the Microsoft website at: http:??www.microsoft.com/downloads/detail.aspx?FamilyID=037f3771-330e-4457-a52c-b085dc0a4cd&displaylang=en.

Meanwhile according to reports IBM Internet Security System X-Force in 2008, showed that only about 11% bhwa attack the security system at large software vendors, namely Microsoft, Oracle, IBM, Apple, and Cisco. This means that approximately 89% of attacks occur on the product safety system software made by other than these five major software vendors.

Graph can be seen in Figure 2. This IBM report can be downloaded pad awebsite IBM, namely http://www-935.ibm.com/services/us/iss/xforce/trendreport/xforce-2008-annual-report.pdf.
Departure from these data, the implementation of SDL in software development is important because it can minimize the attack on the security system. Special application based on Windows platform, Microsoft has issued a document Seecurity Development Lifecycle, which currently have no recent version, ie version 5.

This document can be downloaded at http://www.microsoft.com/downloads/detail.aspx?FamilyID=7d8e6144-8276-4a62-a4c8-7af77c06b7ac&displaylang=en.
SDL documents a number of version 5 of 133 pages, contains information on the SDL methodology and process. SDL methodology process can be seen in Figure 3.
In order to facilitate the implementation of SDL, Microsoft also provides a document Simplified Implementation of the Microsoft SDL SDL is a summary document. This document can be downloaded at: http / / www.microsoft.com/downloads/detailes.aspx?familyid=0BAFF8E8-AB17-4E82-A1FF-7BF8D709D9FB&displaylang=en.

The implementation of SDL on Agile Development

Lots of software development organizations to implement Agile software development trap. In Microsoft's own internal, agile methodology is also applied in the manufacture of products lunak.pada device initially, Agile methodologies do not provide special attention to the security of software systems that dibuat.pada when security is of particular concern Agile user, so the methodology also gives attention to the implementation of the system security.

Microsoft began developing the software by giving attention to the security system known as SDL is applied SDL.daengan, microsoft security system can reduce the gap in its product more than 50%. Application of SDL is sukup heavy, especially on large products such as Windows and Microsoft Office.

SDL document version 5 already tersdia discussion of how mengggabungkan SDL with Agile methodology known as the SDL-Agiel. Processes that occur on-Agile SDL can be seen in figure 4.

Prior to the implementation of SDL-Agile, we do an assessment on systems and processes currently running on our work environment. Microsoft has provided instructions to do an assessment in the form of documents, namely the Microsoft SDL Optimization Model.

This document can be downloaded at the URL: http://www.microsoft.com/downloads/detail.aspx?familyID=90A402A0-CA84-42A2-B2AB-1CE8DE999582&displaylang=en.
This document consists of five documents that discuss some level of optimization of SDL. Based on this document, there are four levels of SDL optimization model, among others:

• Basic
• Standardized
• Advancad
• Dynamic

Four levels of optimization of SDL and its implementation can be seen in Figure 5 and 6.

SDL tool

In the implementation of SDL, sometimes we need a tool that can consistently maintain the predetermined process, in order to maintain the security quality of products manufactured. Microsoft provides a free SDL tool, which can be integrated with development tools such as visual studio. This tool yaituMSF-plus SecurityDEvelopment lifecycle Agile Process Templete for VSTS 2008 and can be downloaded at http://www.microsoft.com/downloads/details.aspx?familyID=c4b44860-cfba-494a-ba43-13c4aecf86af&displaylang=en.
Microsoft juaga provides a tool for the analysis of source code-based technology. NET Framework.

Through this tool, we can know whether the system would potentially threaten the security or not. This tool is known as CAT.NET available for the platform 32-bit and 64-bit and can detect potential vulnerabilities, among others:

* Cross-Site Scripting (XSS)
* SQL Injection
* XPath Injection
CAT.NET 32-bit version can be downloaded free of charge on http://www.microsoft.com/downloads/detail.aspx?FamilyID=0178E2EF-9DA8-445E-9348-C93F24CC9F9D&displaylang=en.

While CAT.NET 64-bit version can be downloaded at the URL: http://www.microsoft.com/downloads/detail.aspx?FamilyID=e0052bba-2d50-4214-b65b-37e5ef44f146&displaylang=en.
In addition to the above tool, Microsoft also provides a kit for developers SDL integrated with the application.

This package can be downloaded on Microsoft's website, which is in http://www.microsoft.com/downloads/detail.aspx?familyID=0FCBA3C7-BC30-47B0-A2F8-2E702720998A&displayLang=en

Service Management Ecosystem

2010-08-27T13:28:00.004+07:00

Ever wondered how conceptually IT organizations actually operate your work place and functioning?

For those readers who have worked in the IT world, especially in an organization or departemenatau IT division in a company, of course, already knew full well why the organization where she worked there, and serves as what is now. Or at least they know why TI needed by the company.

Currently, we semia live in a world that is functioning and running in the concepts and theories of the service economy, or more often referred to as the service economy.

Will be a little difficult at this time to release ourselves from the concept. Because everything we do, feel natural and shaped by one or more services or a service. Almost none of the products we buy and use this as a detached or separate from the concept of service or these services. Since in the morning, we've been woken by an alarm clock which is really a product of sabuah service that allows us to have an alarm clock, without having to know that we pay to make a glass of coffee from a café is also a result of a service. So it is with parking services in the buildings where we can put the shopping vehicle with a better sense of security.

Therefore, it is a service, as a form of manifestation of the service economy. This concept is really simple, where a leyanan will membarikan a particular benefit in our daily activities. Manfat can we call these value.value measured in monetary measures or simple language, money. In this concept, service providers and service users implicitly agree to the value of a service, which later materialized in the form of exchange and the value obtained monoter.
Simply put, we as service users will always pay for a service which we feel are appropriate to what we need. A farmer may be quite happy to pay a glass of instant coffee compared with an upper-class businessman, who did not hesitate to spend hundreds of thousand rupiah a cup of instant coffee.

For those readers who work disebuah company, whether or not the IT companies, of course, understood correctly by the answers to these questions: Do IT where you work is a service business? How exactly it dicipatakan value of IT, and how to measure it?

Currently, the concern of IT professionals in companies tend to start beruba. From an earlier focus on how to manage the PPT (People, Process and Technology) little by little bergeserpada how menelola business value from IT, and how these values are designed, built, and then used in the form of IT-based services.

It seems that, like other service businesses, IT service must also be joining the economy

Service Management Ecosystem

To realize the concept of the economy, an IT ecosystem must be built using service management foundations. In many papers, service management itself is often defined as a practice efficiently manage the IT functions of an environmental fund in which everything may be a service, and all services should be dedicated to the success of business strategy.

Maybe this is too theoretical for most readers. To facilitate understanding, the author will try to explain it in graphic form.

As readers see in the image first, to design, build and then manage IT-based services is formed from a variety of supporting components. The reader must understand, manage an Enterprise Resource Planning applications (ERP) is not enough to manage aplikasinay, but also infrastructure such as networks, servers and storage, as well as software, such as a database, webserver and so forth. Even at the enterprise scale implementation, ERP implementation also requires changes in organizational structure.

Therefore, managing IT-based services also means managing other support services. Construct the points in the management of IT governance framework also governs how third-party services are integrated, such as internetyang access service supplied by your Internet Service Provider (ISP)

Business activity output

Translation of ecosystem service management starts with the end of the objective conditions of existence, yakti output from business activities or business outcome. As we both know, the only two real business outcomes, that is make money and save money so that with such profit every business activity will be maximized.

Diwuudkan IT in the form of a department or division within the company, demanded to be able to collaborate with other departments and divisions in order to achieve this output. How? IT must provide a positive value for the overall business activities.

From where can we seek, whatever ynag values actually produced by IT for business. For simplicity, the authors illustrate in Figure 2.

In figure 2, various TIyang based services generally manifested in the forms of applications supporting business activities, such as HR applications, marketing and so forth.

Different Types of IT and Services

As already writer explained previously that all IT-based services are used by everyday business, in fact formed from other support services.

1. Operation of infrastructure services is formed from the various physical components of IT, such as servers, storage, network devices and so forth. These components interact in such a way, either in combination or divirtualisasi in the form of platform services which can then be used by the layer above it.

2. Utilizing data services and rely entirely on the service layer infrastructure. In this layer, data is stored, managed, moved and transformed. This layer consists of a database management system (DBMS), EDI and middleware platform that will be also used by upper layer.

3. Applications and information services is the place where the business logic sertasynthesized data (information) is located, along with a variety of business applications that are usually used by the user. Function requirements from the business usually controls the output of this layer.

4. IT-based service is a service that is customized according to user needs or business functions other than IT in a company. Basic difference between this layer with the layer underneath is customization. An application may already be customized to support high-availability features to support the needs of users because of the nature of continuous use or 24 hours every day, week and year.

Insource and outsourced Service

The fourth layer on top, like figure 3, has traditionally had heavy titk operations, responsibilities, roles, management, resources and values that stand alone Even though operating in the autonomous tendencies, such a model is actually able to provide agility and rapid response in the event of disruption of IT services.

Figure 4 shows how each layer has a main purpose of combining various resources appropriate to the operational activities of value to users of the ini, which is located right above layer .Where otherwise each layer also use output from the appropriate layer located at the bottom, and ynag generated from the outside environment, combine it with assets, capabilities and internal resources.

External services that are usually produced by outsourced resources digunakn to support and provide value added for services that are operated internally. For example, the role of the internet service provider (ISP) capable of providing enterprise connectivity services, as well as with Internet access required for a company oeleh menjaminbahwa all workers in all parts of Indonesia can access their business applications. Where business applications are operated using internal resources or insourced.

Overall Management Layer

IT Governance are widely recognized by the IT Governance requires a lot of control points to ensure the efficiency and stability of the entire operation of IT services which would in turn ensure the passage of all business activities.

The manager or managers at each layer must know what the criteria for success of any services that exist in these layers, as well as the costs and the resulting value to the business in general. Just as a construction foreman who is always in the field as well as researching all occurrences ynag aware of what is happening around the area of responsibility. He also must be able to make decisions, both strategic mauput taksit, to ensure the quality and value pairs generated from groups working on end-user anyone from his job. Figure 5 shows the concept.

In general, this layer management model is realized in two ways, namely:

1. IT management, which consists of the executive ranks of the organization with the main tasks that tend to strategic, in which they are responsible for the overall operational dynamics of each layer, from the issue of damage on a server until the interruption of a service level of IT services.

2. Control service, which consists of managers who are responsible in part or component of certain aspects of the service.

Cover

Know the concept of ecosystem service management can provide initial views for the readers to read where the IT organization in the future will be in shape. In many authors writing in the magazine PC Media, the authors often emphasize the final form of any IT organization ynag will ultimately lead to the concept of service providers.

Why? Because, one of which is the most suitable model to be able to survive in the service economy. Service provider model is a model of business organization that is able to implement the jargon of "make money and save money." What would happen if the board of directors at the company you decide that the cost of IT services provided by IT departments or divisions of the company, proved to be more expensive than the cost of IT services provided by third parties? I could have entire IT departments or divisions in the company you work for frozen, on-even spin off or sale. Certainly none of us, if it is in such condition, want to experience that to happen. So, Datu-datunya strategy to survive in the future is to adopt a model of service management organization operating ynag in general as in this paper.
Hopefully useful.

TRICKS AND TIPS FOR WINDOWS 7

Create Private Desktop Themes

2010-08-22T21:47:00.008+07:00

Desktop Themes like a complement to the personal computer, either desktop PC or your laptop. No harm, if then want to create their own desktop themes as you wish.

If you refer to the websites in cyberspace that every day we will visit lots of different kinds of templates available desktop themes, wallpapers are ready-made and ready for use. One or many of which are in accordance with our wishes and tastes. This view of the creators who have the same taste as us.

Then, if later we want to modify the desktop themes, in conformity with our desires or even create a desktop themes myself, if I could? The answer is, you can. Of course with little effort because it required "effort" to create a more customized desktop themes according to your own tastes. However, need not be discouraged.

On the Cover Story this time, we will provide guidance how to create desktop themes easily, step by step. Of course, with the help with some desktop customization tools easy to use and have become standard tools for creating custom desktop themes, among which are Samurize, RocketDock, Rainmeter, and Energy Desktop.

In addition to standard tools, there are also several additional applications that need to be in sinergikan with standard tools that will create something other than the other. Certainly does not eliminate the impression that you can create desktop themes with great ease.

Without more broadly at length, please follow the step by step of making desktop themes according to your own desires.

However, as we used earlier to remind you, do not forget to do a backup first telebih on your computer system to avoid unwanted future, if you use applications that we provide. All kinds of damage to the system and lost data on your computer is not our responsibility.
Good creativity!

STEP 1

Create Your Own Icon and Shortcut
We've provided some applications that can be used. Many are in fact, free applications you can get for free on the internet. But here, we only focus on using multiple applications like Rocketdock and Rainmeter.

For this step, necessary Rocketdock applications. Please you first install the application to your PC. Or you can download and read his site in http://rocketdock.com/.
Next, extract the files Stackdock-let which has also been provided. Or if you want more information about these add-ons, please visit their website at http://rocketdock.com/addon/docklets/1791. Install or copy files into folders DOCKLETS Stackdoklet contained in the folder you ROCKETDOCK applications. Obviously, this application contained in the Program Files folder in your OS system.

After finishing the add-ons include these, then run the application Rocketdock. It will look new navigation bar at the top, if you ever peek or use Machintosh, certainly will not be familiar.
Some standard items you would find on the navigation bar. Of course, the navigation bar so can be modified, especially to include some important short. It is the use of add-ons Docklet you have previously installed.

The next steps is to create a specific shortcut you want to appear on the navigation bar.

1. Stackdocklet." onmouseover="this.style.backgroundColor='#ebeff9'" onmouseout="this.style.backgroundColor='#fff'">At the cursor position on the navigaton bar, click the right mouse button and then select the Add items> Stackdocklet. Then will come a new shortcut icon shaped transparent box.
2. Then, right click on the icon, which you just created. Select the option settings icon and then will appear the windows setting for stackdocklet.
3. In the window, put the folder that you want to shortcut it, by clicking on the right ... which means the browser window. Select a folder anywhere, it's up to you. When finished selecting a folder and then click OK.
4. Later still in the window, you are required to choose the shortcut icon for the folder you created it. Click the sign ... of the Icon option, and then will appear baru.Pilih window default icon that has been provided according to your wishes. In addition, you can also create their own icon, not be stuck with the default icon that is on him. Make sure your own custom icon to use. Png or. Ico.
5. Still on the window settings for Docklets Stack, at the bottom of the window you will find a selection of modes. To form automaticnya, shortcut folders that you open will form in the Grid. However, if you want to be creative and change the form of a rather unique, you can memelih Mode to Fan. This option will be the folder you want to open a curved shape, like a fan. If the tone of jelly, so follow this form of MAC OS operating system. After finishing all the settings, then click OK.
6. Supposedly, if you follow from the beginning, this work will be successful. Try first by clicking on the navigation bar you stackdock.
If you want to add another shortcut, start again, just as was done with the first phase. Until the number of shortcuts that you want fulfilled.

More Information:

Furthermore, more visible so that your desktop tidy, remove all the shortcuts that are not useful or that at least you seldom use. However, if you still want to use it or indeed need these shortcuts, gather on Selah a folder (create a new folder).

Do it in a way Cut or Paste for all these shortcuts. Location is up to your history folder, and then create a folder to be one stackdock shortcutdi in your navigator bar. Or in other words, change into Stackdocklets.

Special Shortcut utnuk Mycomputer and Recycle Bin, not recommended menggunkan Stackdocks. So, let alone first.

STEP 2

Make Your Own Desktop Themes

To create desktop themes according to your own desire, indeed bother gampang.Kenapa difficult because it must have the creativity in creating a desktop themes.

If not keratif and "sense of art" you are less then the result would not be maximal. Why is easy because if you sort of google search engine, you'll find lots of applications that support desktop Themes own making, ranging from the "complicated" for use, until the most easy. From ynag licensed for free, GPL, trial, until paid.

Here, we've picked some desktop applications Themes for free, but it is not difficult to use them. But for more focus, we only give step by step of making Desktop Themes using Rainmeter applications only.

Rainmeter this application, we feel most friendly to use. Its features are also quite complete. With this application, you will see the weather forecast bias, tatus your PC, the date, hour, and so indirectly, on your desktop.

We already provide these Rainmeter application for you. If you want to learn more detail again, your bias http://rainmeter.net/RainCMS/ visit. There are two types of applications that we provide, which is used for 32-bit and 64-bit. For example here, we use a 32-bit.

Rainmeter to install applications in your PC, follow all instructions given.
After doing the installation Rainmeter, then install the skin also special for Rainmeter. Here, we only include two pieces of skin only, ie Circuitous and HUD Vision. There are still many in fact, the bias obtained skin. Read more, you can choose and download it directly in http://customize.org/rainmeter.

We will cite utnuk Circuitous extract. Then, copy and paste the contents eluruh you extract the file.

Rainmeter enter into folders. skin files exist in the program folder on your PC.
After all the above steps are done you are taking, meaning the application rainmeter and skins should have a direct bias you run.

After running the application, you can make settings in accordance with the desire. Follow the steps below:

1. Before running the application Rainmeter, it never hurts you install applications Rainlendar. This application is used to display the date, event and to do lists that we feel will be very useful for you. The results when you run the application, it will look like the following.
2. Before running the application Rainmeter, change your wallpaper first. If the wallpaper is already in accordance with what you want through the replacement step, we provide a wallpaper from the game Assassin Creed 2. Another wallpaper you can find on the internet, with various options. The trick is easy enough, right click your desktop, then will the new munculwindow. Select the desktop tab and then click the browser button. San then the folder window will appear. Select one of your images that will make your wallpaper. Then, click open. Once completed, then click the Apply button and your wallpaper akanberubah. We examplize here is a wallpaper Assassin Creed 2 we had to include.
3. After that run the applications you have installed Rainmeter earlier.
4. After the application runs, see the shortcut on the taskbar at the bottom right corner. There are a pictorial icon like drops of water, right click on the icon.
5. After that will appear in a new window, and select configs. Enable the programs you need to ditampilan on the desktop. As examples only, which is activated CLOCK, DATE, CPU, HDD1, HDD2, Network Traffic Download. After the show, set the location according to your individual tastes.

More Information:

You can download the skin according to your needs and tastes of each website on the link we've provided above. Here, we only give two examples of skins that you can make as an experiment.
Our message, use this application only as needed because if you use too much it will take considerable resources from your PC. Certainly be very berpengaruhpada overall PC performance later.

Please experiment itself because in the beginning, we have pointed out that you must have a "sense of art" rather high to create a new themes. Not just nice to see, but also bad for your look, but also delicious viewed by others.

STEP 3

Eliminate the Recycle Bin

You've succeeded in setting up and Stackdock Rocketdock. You also have managed to do the installation and settings using Rainmeter and Rainlender applications.

Here is left on your desktop is the recycle bin icon is really important, but it is quite disturbing beauty to your desktop. And when it wants to remove them with a way to delete, this icon can not be deleted (access denied).

If you are unable to delete icon, so it needed manual removal, with the way in and change the registry value. Is a bit dangerous and risky indeed, but with the steps that we provide, you will not make a fatal mistake.

Our message, before making the replacement registry, backup registry first, so any time you want to restore the initial value, it can be done:

1. Run RUN program, from the start menu. Will appear in a new window, then type regedit, and then click ok.
2. Furthermore segistry editor window will appear.
3. Software > Microsoft > Windows Current Version > Explorer >Desktop > NameSpace." onmouseover="this.style.backgroundColor='#ebeff9'" onmouseout="this.style.backgroundColor='#fff'">Select HKEY_LOCAL_MACHINE> Software> Microsoft> Windows Current Version> Explorer> Desktop> NameSpace.
4. Delete registry 645FF040-5081_101B_9F08_00AA002F954E FOLDER.
5. Close the registry editor window. Next, look to the desktop and do a refresh on your desktop. If not successful when doing a refresh, immediately reboot your computer.

More Information:

Browsing Over Brief With Accelerator

2010-07-06T11:50:00.004+07:00

Accelerator can cut a lot of time that you use for browsing, one of the favorite things in Windows 7 is the Internet Explorer 8 (IE8) and Accelerator feature. We never realized how useful the feature, until we use it routinely. We will eksplorai IE 8 Accelerators feature and how to get the best from him. Once acquainted with the IE 8 Accelerators feature and know how to get the best from him, as a follow up we will see some of the best for your Accelerator.

Whether the accelerator?

Accelerator perform functions in accordance with its name. They accelerate your ability to get access to various types of web-based search that is used every day. You just highlight the text that interests you, click the Accelerator icon and immediately launched.

For example by default Accelerator you can quickly send the terms to the search engines or site translators, send a paragraph to your blog or via e-mail. Although associated with less all the default Accelerator Microsoft, does not mean that everything outside as well. There are many third-party Accelerator you can choose. Let's see how to use the default Accelerator. Next, we will see the addition and management of the Accelerator.

Using Default Accelerator

The best way to explain how and whether the Accelerator is to directly try. So suppose you're looking for a new job and find an appropriate job in the city that you do not know. To find out where the location, you will first highlight the name of the city. You'll see when you click the icon Accelerator, accelerator list will appear. Select a folder will appear with Bing and a small map. If you want more detail, click on the map and a larger map will appear in a new tab.

Another example, suppose you read about the game Guitar Hero: Metallica and want to know more about Metallica. Simply highlight Metallica, click the Accelerator icon, and then click the search with Bing, A new tab will appear and display the search results, provided by Bing. Accelerator saves a few steps. No more copy-paste text, open a new tab, access search engines, and click the search button

Adding Accelerator

As mentioned earlier, there are many third-party Accelerator that can be selected. You can replace the existing Accelerator with your favorite. To see a list of Accelerator, click Page, All Accelerator, Find More Accelerator. A new tab will appear and display a page of Internet Explorer 8 Add-Ons Gallery. You can search for Accelerator who want to use and install it by clicking the Add button to Interet Explorer.

Accelerator Configuration

If you select a command on the sub menu Accelerators Manage All Accelerator, you will see a dialog box with the Manage Add-Ons Add-Ons Accelerator Types selected, as shown in the picture. From here, you can remove the Accelerator, do disableAccelerator Accelerator and the default setting for each category.

Amazon Search Suggestion

If you shop online at Amazon.com then you'll want to install and use the Amazon Search Suggestions to help you make your purchase decision.

Define with Wikipedia

The greatness of Wikipedia content is somewhat controversial, but still became one of the free Web-based most popular on the Inernet. With almost 3 million articles then you most likely can find what you're looking for. This makes Define with Wikipedia to be very good for Accelerator pelengkapyang default.

HTML 5

2009-10-09T20:04:00.007+07:00

It was about 10 years of HTML 4.0 / HTML 4.01 is known in the world of web development, time to switch to HTML 5?

Year - this year is a period in which web technologies develop so rapidly. Important point of the current web technology is how a web application as an alternative to the more trusted to perform various forms of activities that used to only be done by desktop applications

Many things have been achieved by a web application up to this day, we often find a web application for office and business, a web-based online games, online document collaboration, and a series of other activities that may not have been imagined in the past. Technically, is still a limitation is the ability to access the web application level low operating and accessing computer systems, which of course also limited the browser as the client side.

May 2009, when Google announced a new service called Google Wave and demonstrated at the conference Google I / O, again made a breakthrough with the display capabilities impressive web applications, such as real-time collaboration between the website, or drag and drop images from desktop to the browser. Google Wave is an example of a web application that implements the HTML 5, HTML version will come to break the limitations of HTML for this

HTML from time to time

In contrast to the language / script complicated programming, HTML (Hypertext Markup Language) is a simple language, easy, structured, but often underestimated his ability, far below the JavaScript, especially server side scripting like PHP, the programming language. NET, and Java. HTML? Best just to make a table or form input, may thus be seen.

But talking about HTML, will not escape from one of the important role in the world of the Internet, HTML is a standard document that you present to the HTTP (Hypertext Transfer Protocol) a protocol that sends data from a web server to a web browser that allows document sharing, although users located in different continents

We are now using sophisticated class browser Firefox, Safari, or Google Chrome is capable of displaying interactive web content, might be surprised with the first penggun atempo already very satisfied with Mosaic, the popular web browser at the time - which has a remarkable ability (at the time), which can display images along with the inline text (because before that, the image is usually displayed separately from text) Mosaic display Example:

HTML version of the trip includes unique. The first HTML specification which includes 22 elements in 1991, followed by HTML +, HTML 2.0 and reached in 1995. So there is no known HTML 1.0

Of HTML 2.0, HTML 3.2 continue to announced by the W3C (World Wide Web Consortium, an organization to determine international standards Worl Wide Web) in 1997, introducing features including tables, applets, superscript, subscript, marquee, and so on . HTML 3.0 is available, but only a draft and not a formal specification

In January 2008, was announced as the HTML 5 draft. Although his status has not a formal recommendation, some HTML 5 specification starting layout supported by a variety of layout engine and the leading browser. HTML 5 specification is done jointly by the W3C and WHATGW (Web Hypertext Application Technology Working Group). WHATGW is a community which was founded a few individuals from Apple, the Mozilla Foundation and Opera Software.

Writing basic HTML is as follows 5

HTML 5 will memeperkenalkan API (Application Programming Interface) further expand the boundaries of HTML, among others
1. Offline Data Storage
2. Drag and Drop
3. Geolocation

One new element in HTML 5 is the canvas. Examples of its use as follows:

Furthermore, we can insert an object that we want to canvas the area, the following example will display shaded text using JavaScript and the DOM method (Document Object Model). Read more code as follows:

Introduction to Character by Using Artificial Neural Network (Part 1 from 3)

2009-10-02T17:06:00.009+07:00

Wonder how the character recognition application can recognize the image and converts it to characters or text may be in the edit? This first section will discuss the basics of his theory.
Imagine you're reading a long article in a magazine. Then, you are interested to send the contents of the article to one of his colleagues by e-mail. In order for the article is more flexible, you think to type it so that it can be sent in text form. You start your typing and it spent 3 hours until finally the article is finished

Technology OCR (Optical Character Recognition) will resolve the issue. To article with the scan, will produce an image (which must have text in them can still edit) for the text in the image can be converted into text that can be edited, it is necessary to an OCR software, which will process the image and produce output text form.
Talking about OCR software, actually is taken from technology Artificial Neural Network (ANN) which is one part of the field of artificial intelligence. Implementation of the ANN is often encountered in a variety of intelligent computing systems such as to make predictions (value stocks, weather, disease diagnosis) classification (the imposition of fingerprints, faces, or certain forms of) filtering (removing noise to the signal telephone) etc. What is interesting from an application ANN is its ability to learn so that more data is given, then the application becomes more intelligent (more accurate in doing an introduction)
in this article, we will learn about the basic principles of ANN to perform character recognition as in the case above.
ANN Basic Concepts
ANN workings based on the workings of the human brain in processing information. In the human brain there are 100 billion neurons or nerve cells connected to each other. In each neuron, there are sections called dendrites, soma (or cell body) and axon.
Dendrites are shaped like tree branches, useful for receiving input signals at the soma accommodated. If the input signal has enough, then the cell is activated to carry the signal output via the axon. Axon is a duty to spread signal to the neuron's dendrites through the narrow gap neighbor called synapses
ANN is a mathematical model of neurons that possess the human brain. The components consist of:
• Input: a single attribute or a variable that should be in numerical order code be computer processed. The input data can be a number, qualitative, true / false, etc. Because the neural computing can only process the numbers, it is a problem involving qualitative attributes or pictures, must be processed in order for the numerical data that can be read by a computer. In the case of processing an image, this input bits of the image to be processed.
• Output: a solution to the problem, recommendations, category, or estimates. In the case of OCR applications, the desired output is the letter corresponding to the input image, so if there are 26 types of desired outputs (AZ) then the amount of output can be as many as 26.
• Weight: is the relative strength of an input in determining the value of output. ANN system is called "learning" when the weight is adjusted such that the final results of the ANN system approach (or equal to) the desired target.
• Summing Junction: find the number of weights of all input elements for each processing element. Multiplying the input value (X) with weight (W) and summing them to generate number of weighting Y. The formula to get the output on the Summing Junction is:

Where n is the number of inputs (i), w is the weight for each input and b represents the bias. The result is normalized with an activation function. Activation functions: a function that determines whether a neuron produce output or not. Usefulness of the activation function in is:
• To normalized data (example: 1 = true and 0 = false)
• Detects when a threshold is reached (example: Y <0.5 then set Y = 0 and if Y> = 0.5 then set Y = 1).
How to Make ANN Can Learn?
One of the most important concepts of ANN is the learning process. The main purpose of the learning process is to make arrangements on the weights on ANN, thus obtained final weights appropriate to their training data patterns. The learning process usually involves three activities:
• Calculate output
• Comparing the output with the desired target
• Adjust the weight and repeat the process
the learning process begins with a set weight, can use a specific rule or given at random (as will be adjusted) differences between actual output (Y) and the desired output (Q) is called delta. The goal is to minimize the delta (if possible, to zero) Delta can be as small as possible by changing the weights. A key part of the learning process is to change the weight in the right direction, making the delta gets smaller. When a certain weight of the delta becomes very small (or zero) it is expected that for similar inputs, will give results close to the true target.
For example, suppose the input binary 0101 0111 is trained to produce output 1 (the target). After going through the weight adjustment process, could finally get a combination of weights such that the output is 0.97 (or in other words delta of 0:03) with such weight, if any input is approaching 0101 0111, 0001 eg 0011, then the expected output is still close to 1. This principle is a principle in the character recognition applications.
For character recognition application, we will use the method BackPropagation. Although not the best, but this method powerful enough to be applied to character recognition applications.
Back Propagation method to use, required ANN architecture called multilayer networks. What is meant by multilayer network is a network consisting of input layer, hidden layer, and output layer. The difference with single-layer network is the existence of hidden layer between input layer and output layer.
In the above example there are 3 pieces inputs, 5 hidden units in the layer and 2 fruit output in the output layer. For each input that is connected to a unit in the hidden layer, has the weight of each (which will be adjusted to certain rules) If the weights connecting the input to the hidden layer units we call V, then we can define Vi, j as the weight that connects input to i with the unit to the hidden layer. So for the first output of hidden layer is formulated with:

Where xi is the i input and output on z_inj is hidden layer to the j unit that has passed through an activation function. As mentioned earlier, the activation function is a function that is used to perform data normalization. The sum total of xi with vij can achieve - ∞ to + ∞. For that, the value must be normalized. There are several activation functions that can be used, but in this application we will use, the sigmoid activation function defined by:

By inserting the parameters in z_inj as activation function obtained:

For the last output in the output layer, can be formulated by:

Where is the weight wjk linking units in hidden layer with output, and Yk is the final output has been normalized by the activation function.
Note that the data is input layer, will calculate (In total and is calculated with an activation function) and then brought forward to the hidden layer. From the hidden layer will be processed in the same way and brought forward to the output layer as the final output. This step is called the forward pass ... (to be continued)

Hardware Test: ZOTAC GeForce 9600 GT Supreme

2009-09-14T16:54:00.002+07:00

Video Card Low-End NVIDIA PCI Express

Maximalists probably is the right word to describe the video card from ZOTAC this one. Where are here seen ZOTAC efforts to bring the maximum level of performance of a GeForce 9600 GT. And that while maintaining the standard of design, such as single-slot HSF solution and guaranteed operational from using the best components. To enable this, one of the most visible modifications is the implementation of a fairly extreme overclocking.

Along with it all, ZOTAC still keep bidding prices are not too high. Therefore, he still can get into the test with a limit class products from low-end price range below $ 100. For the nominal itself, these ZOTAC products are almost close to $ 100. However, ZOTAC bundle still includes plenty of users, and it also became one of the benefits. From the fact that, the words "Supreme" describes quite well be his wish as the best product and offer it with the lowest possible price.

Switch on the performance, he got a high score on the test overall with a range of 93%. It still looks fluctuations in some tests, but it shows not only the hardware side of it that affect performance, but also to the software or the accompanying application. With the extreme overclocking on the GPU, theoretically rendering capabilities will increase. And he was convincing enough to test for the type of gaming Crysis and OpenGL from Unigine

Graphical User Interface in Java (Part 2 From 3)

2009-09-13T22:19:00.025+07:00

Make a window in Java is easy. Unfortunately, to put the components into the window is not as easy as making

Know Your Swing components

In section 1, has discussed how to display a window using Swing in Java. In this second part, we will learn to Swing lay various components in the window. Some of the most common components used are:

a. JLabel, is used to display labels or text in the window
b. JTextField, is used to receive from the user enter text in the form
c. JButton, used as a button that can trigger an event when the click
d. JCheckBox, used as an option that can be checked
e. JComboBox, used as an option in the dropdown form that lets users choose to type or click one of the options available
f. JList, used to give the user a list of options
g. JPanel, used to group several components or can also be used as a canvas area to draw geometric shapes. JPanel component is not a component that can accept input from the user, but only serves as a container for accommodating other components

Some components easy to use, but a few more (like JTable) requires a slightly complicated management

Placing Components

Java is object-oriented programming language, so that all components of the object, to put the components into a window, we need to declare the first component, then we call the Add method to put the object (component) is. Not placed directly on the window, the object of Lay on a content pane, which is a layer of the window or frames that has been made. This concept will be a bit confusing, but we will try to see how the actual philosophy behind the laying of these components.

As a component to JFrame and display screen, we will see a window that seems to be very easy to put components in it (button, textfield, label, or other components), but in fact behind these frames, there is the layer above it called Root Pane. Root Pane itself has four parts:
1. Layered Pane.
2. Content Pane.
3. Glass Pane.
4. Optional Menu Bar.

The following illustration shows how the layer structure of a frame. Each layer has its own function:
• Layered Pane, a layer that can accommodate overlapping components. When we add components to Layered Pane, then we also need to determine the depth or normal termed Z-Order (sequence) component is to determine the order of stack components.
• Content Pane, a visible layer by default and used to accommodate the components, including the menu bar. If we want to add menu bar to the application, then the menu bar will be placed on the Content Pane. For examples of the next program, all components will be placed on this Content Pane.
• Glass Pane, an outer layer and hidden by default. If Glass Pane is displayed, then this layer will cover the layers beneath. Glass Pane is useful if we want to show the components placed on other components (or also to capture an event)

For example, we will make a how to put a button component on the Content Pane. The steps are as follows:
1. Create a frame / window to accommodate the components

JFrame frame = new JFrame ();

2. Declare an object components (eg labels)

JLabel label = new JLabel ( "This is text");

3. Add object (component) is in the Content Pane (because they could not be added directly to the frame). To add to the Content Pane, we need to get active pane then using the getContentPane method. Content Pane of the reading results is accommodated in an object of type Container:

/ * Declare an object of type Container for accommodating Content Pane * /
Container content = new Container ();

/ * Get the Content Pane of the time frame is active, and stored in content object * /
content = frame.getContentPane ();

4. Add the components in the content pane through objects that have been prepared in step 3 by using the method add

content.add (label);

5. Last is the display to determine the size of the frame with the method setSize, show the frame with setVisible method and stop the program when the close icon is closed

frame.setSize (400, 400);
frame.setVisible (true);
frame.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);

For more listings are as follows:

/ * Listing 1 - GUI2.Java * /
1. import java.awt .*;
2. import javax.swing .*;
3.
4. public class GUI2 {
5. public static void main (String [] args) (
6. JFrame frame = new JFrame ( "Demo Component");
7.
8. / * Declare an object of type Container for accommodating Content Pane * /
9. Container content = new Container ();
10. / * Get the Content Pane of the time frame is active, and stored in the object

content * /
11. content = frame.getContentPane ();

12. JLabel label = new JLabel ( "This is text");
13. content.add (label);
14.
15. frame.setSize (400, 400);
16. frame.setVisible (true);
17. frame.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);
18. }
19. }

Set the layout for laying Components

After putting the components into a window / frame, does not mean everything is easier. The next challenge is how to manage if there is more than one component that would appear (in fact, in a graphical application, it will always be more than one component)? If you just add the method calls in the call many times to put more than one component? Which will be placed on those components? Will be sorted from left to right? Will be arranged from top to bottom? Or would be stacked?

This question will be answered with the layout. Layout is a key component of how to put the components into the frame (or window) that exist. Each pane has the default layout. For example, if a frame is placed on a button, then the default button will meet all existing frames. For example, if we add the following line to the 12 and 13 in listing 1 (GUI2.java) becomes:

So view obtained is as follows:

Button will cover the existing text in the frame. To overcome this in, Java Swing layout provides 4 models that can be used to organize the components, namely:
1. FlowLayout. As its name implies, this type of layout will drain all the components from left to right. If the frame is not sufficient, then the component will be put under. Use of this Flowlayout suitable for simple applications that do not require a lot of components.
2. BorderLayout. This type of layout has five division areas, namely north, south, east, west, and central
3. GridLayout. Divide the window into the grid area / table with a number of specific rows and columns.
4. GridBagLayout. Similar to GridLayout, but the size of each grid can not match. Use GridBagLayout is very helpful to put the components with more custom, but a little complicated way of use.

How to apply the layout of the 4 top models in the program?
We need a method called setLayout which to set a layout in a container. Container itself can be obtained through the method getContentPane as exemplified in listing 1

A simple example to put the 4 button in a window by using the FlowLayout layout is as in listing 2 (Flow.java)

The resulting display is as follows:

If we do resize the window, then the components will continue to follow the flow from left to right, then down just below

By default, the alignment for the components are arranged in the middle. We can set this alignment through the constructor the first time declared a layout. There are three alignments that can be given to this arrangement with FlowLayout, namely FlowLayout.LEFT, FlowLayout.CENTER (default), FlowLayout.RIGHT. For example, if line 15 is converted to:

15. content.setLayout (new FlowLayout (FlowLayout.RIGHT);

Then all components will be placed right average width of the frame following the

The distance between the components can also be arranged through the constructor when declaring FlowLayout object. For example, if we want to set the horizontal distance between the components of 20 pixels and a vertical distance of 5 pixels betwen componen, then in line 9 can be converted into

9. content.setLayout (new FlowLayout (FlowLayout.RIGHT, 20, 5));

View obtained is as follows:

The simplest of all forms of regulation is FlowLayout. Consequently not much can be done if we want more flexibility in managing positions.

Layout of the 2, which is BorderLayout provide a more sophisticated setting, namely by dividing the window into five areas, namely north, south, west, east and center. 5 areas to be determined at the time of calling Add method to put the components

As an example of the BorderLayout, consider Listing 3

/ * Listing 3 - Border.Java * /

View is obtained as follows

Like Flowlayout, BorderLayout can also set the horizontal and vertical distances of each component. This setting is placed on the constructor when declaring BorderLayout object. For example, if the horizontal and vertical distances to change to 10 pixels, then the declaration on line 16 was changed to:

content.setLayout (new BorderLayout (10, 10)

And the resulting display is as follows:

If FlowLayout and BorderLayout are less satisfactory, we can try to GridLayout. Assuming that the frame / window arranged in tabular form (consisting of rows and columns), the settings component position can be easier.

For example if we want four buttons arranged in a 2x2 table. Although the resize frame, but both are still arranged in 2x2 formation. This of course can not be done by using a BorderLayout and FlowLayout.

We will make these formations, as in Listing 4

/ * Listing 4 - Grid.Java * /

Display becomes as follows:

Line 15

content.setLayout (new GridLayout (2, 2));

Indicates the settings in the form of rows and columns. Meanwhile, to set the spacing between the vertical and horizontal components can be done in the constructor. For example:

content.setLayout (new GridLayout (2, 2, 10, 5));

Will provide the horizontal distance between the components of 10 pixels and a vertical distance of 5 pixels components

Exploiting Panel to Manage Layout

So far, insight a frame or window is only possible to use just one type of layout. What if we want to label and the textfield is set by using FlowLayout layout, and to Button set by using FlowLayout?

The answer is using the JPanel. JPanel is a blank area that can be used for:
• On the contents of other components
• Draw a graph or geometric shapes

Components are placed on JPanel can be set using a particular type of layout, then JPanel can be placed on a frame by using a different layout

As an example we want to make a set of buttons placed on the bottom of the window. If we use a BorderLayout with the South's position, then what happens is Button 1 will be stacked by Button 2, Button 2 will be stacked by and Button 3 Button 3 Button will be stacked by 4. The result is shown in the frame is just button 4.

In this case, we can use JPanel. In JPanel, we can fill in the Button 1, Button 2, Button 3, and 4 Button using FlowLayout. Then we put it on the frame JPanel with BorderLayout in south position.

5 Consider the following listing:

/ * Listing 5 - Panel.java * /

Line 10, we define an object type is then set JPanel using FlowLayout layout (line 17) At the panel, added button as many as 4 pieces that will flow from left to right.

After the panel on the contents of the button, the next is putting the panel by using BorderLayout (line 23) and placed in the SOUTH position (line 24). Display of Listing 5 is as follows:

Once we know how to put the component on a frame, the next section we shall understand more deeply for each component, and how to do event handling of these components .We will discuss the Graphical User Interface in Java Part 3

Graphical User Interface in Java (Part 1 From 3)

2009-09-07T17:14:00.003+07:00

Frankly, graphics-based applications are always more interesting than the application of command-line based. And the good news, building graphical applications in Java, it is not as difficult as imagined

Java is a programming language first released by Sun Microsystems in 1995. Java philosophy of "Write Once, Run Everywhere" make Java become one of the popular programming languages today. According to the official website of Java, Java technology currently used in 4.5 billion devices (more than 800 million PCs, 1.5 billion gadgets, 2.2 billion smart cards) and still did not include use in printers, web-cam, games, car navigation systems, medical devices, etc

Know Java

If you've heard of Java, but not so deeply in the program, chances are you will be confused with terms such as Java 2 SDK, JDK, Java Applets, Java Script, Java Runtime Engine (JRE), Java SE 6, etc.

All of the Java technology, but if you want to learn to develop Java applications on a PC, the Java SE (Standard Edition) is an appropriate option. Whereas if you just want to run Java applications on a PC, you need a Java Runtime Engine (JRE)

Java SE name used interchangeably with the Java Development Kit (JDK) or Java Software Development Kit (SDK), Java 2 Standard Edition (J2SE). The latest version of Java SE is the version released on May 28, 2009, the Java SE 6 Update 14 that claim to support Windows Vista SP2, Windows 7, Internet Explorer 8 and Windows Server 2008 SP2. You can download it for free at the Java site, http / /: java.sun.com / javase / downloads / index.jsp

Java SE Development Kit (JDK) has the form of files Basic Tools:

• Compiler name javac
• Launcher or interpreter to run Java applications, called java
• Java debugger called jdb
• Viewers applet called appletviewer
• Disassembler for file.class named javap
• Generators for API documentation is called javadoc
• manager JAR files (Java Archive) named jar

When you first learn to create applications using the Java compiler javac, and java launcher will be your best friend. There are three major lines of program groups can be created with the Java language (Standard Edition), namely: applet, a Java application is run through the browser by calling the HTML tags - the same as if we are to display an image using HTML tags.

Java applications (usually called "application" only) Shared longer be: Application GUI (graphical user interface). I.e. applications that use graphics display. These applications can be run on the local computer, just like we run other application programs
a. Application command line, It is limited to applications that display text, which is run and displayed in the command-prompt
b. Package (or library Java) Package itself not to run, he only provides a set of Java classes that are considered useful and the public to be used again

Making Java Programs

Step - step in making Java applications are as follows:
1. Making the program text (source-code) with the Java language syntax. You can type in source-code in any text editor and save it with java extension.
2. To compile the text into a Java application program
3. Running Java applications with interpreters or the applet, the applet viewer if the shape

For example, we will try to make the first program in Java:

1. public class Hello {
2. public static void main (String [] args) {
3. / / Display message
4. system.out.printIn ( "Hello, world!");
5. }
6. }

Make sure the file name is Hello.java

Description:
1. The first line: make a class named "Hello". The entire framework in Java is always in the class
2. The name of the class must always be the same as the file name
a. In the first line, is the Hello class name and file name are Hello.java
b. Not allowed to use a different name, eg file name replaced with Halo.java. This will cause an error during compilation

3. On the second line written method main (). This method has an array of String parameters. This is a String array argument of Java programs.
a. A Java application program must have the main part, a method called main ()
b. Method main () function as a starting point of the program. That is, when the Java program is run, method main () always run the first time
4. In the third row, there are comments
a. Comments will not be compiled and run
b. Compiler will ignore the comment lines
c. Comment line begins with a slash character uses two "//". (comments by early signs "/ /" should only be on one line)

5. The fourth line is the command to display the message
a. The message of the string "Hello, world!" Displayed by the method called printIn ()
b. PrintIn method () is part of the variable named out
c. Meanwhile, out is part of the class named System
d. To call the dot operator (".") is used to System.out.printIn ()

The process for compiling Java programs are:

1. Once finished creating the Java file, the next step is to compile a file using javac.exe (Being in the directory \ bin \)
2. Running the compiler command in the command-prompt

> Javac Hello.java

3. Hello.class which generated files are output files from the compilation results

Hello.class files can be directly run the program using java.exe.

> java Hello

A good start in learning Java. However, it is difficult to be able to develop an application that has the interesting interface simply by relying on command-line display as above. That's why we need a user interface is graphical, and Java has provided.

Beginning with A Window

Graphics-based application begins with making a Window. In the visual programming language (such as Visual Basic), this window is called the Form, Java name with a Frame. After making our frames can put all the necessary components, such as Menu, Button, Checkbox, Text Field, or whatever you want to put in there.

Step in making the frame in Java is:
1. Creating objects by using JFrame class (a class provided by Java for creating graphical user interface)

JFrame frame = new JFrame ();

2. Adjust the size of the frame. If size is not specified, the default size used is 0.0.

frame.setSize (400.400);

3. Displaying frame

frame.setVisible (true);

we try to compile into a complete program

because we define the class name GUI1, then the appropriate file name is GUI1.java.

Description:
1. The first line is the command:

import javax.swing .*;

This command shows that we need a swing library (package) is located in the javax. Without doing import, we will not be able to make the frame, because the frame class defined in the javax.swing package.

2. The third line defines the class name is used, namely GUI1. Storing files must be done by using the name GUI1.java
3. In the fourth line write method main () which is the main program.
4. The next lines are to make an object called a frame, determining size, and displays.

To be able to see the results, we need to compile it using javac

> Javac GUI1.java

If successful, we run the compilation by using Java.

> Java GUI1

Display that appears is an empty frame with a size of 400x400. Note, this frame does not appear in the command-prompt (which used to run the application), but emerged as a new window, while the command-prompt still active.

Problems arise when we closed the frame with the click icon close. Command-prompt does not return to a state ready to accept commands, but still seemed GUI1 running applications (although the frame has been closed)

For that we need to determine the action performed by the application close icon is clicked. We add a command that is placed on line 9

frame.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);

If we do not determine DefaultCloseOperation, so when users click the icon close, just hide the application frame. But really, the applications remain in memory, which is why the command-prompt as if it were still running the application (do not return to the prompt and ready to receive another command) In this condition, we may be forced to close the command-prompt or by pressing Ctrl + C in the command-prompt.

Little is still annoying in this frame is that this frame does not have a title on the title bar. We can add a title with one of two ways:

First at the time of the object frame:

JFrame frame = new JFrame ( "TitleFrame ");

Or can be made by calling setTitle method (which can be placed after the making of objects)

frame.setTitle ( "Title Frame");

Ideally we first determine the title of the frame, and if in the middle of the application is required to change the title, we can call this method.

Just a note, form the frame to display a Java application will greatly depend on the platform that is used when running the application. If you use the operating system, Linux or Mac, then with the same program, will produce a different frame models.

Then, the next question is how to add components (such as button, label, combo box) on this frame? We will discuss the Graphical User Interface in Java Part 2

Game Test: Ghostbusters The Videogame

2009-09-07T16:55:00.003+07:00

For most young people today, Ghostbusters may not mean anything. However, if you are a teenager at the end of 1980, guaranteed you will be surprised and delighted exclaimed "Wow ... Ghostbusters!" Yes, indeed cartoon movie ever been phenomenal the past two decades. Now as a 25-year anniversary of this series, Atari published a game of Ghostbusters. However, the developers took the character representation instead of wide screen film version.

This game has a setting in the year 1991, exactly two years after setting the second movie. The story begins when a wave of supernatural from a museum that caused all the ghosts released into the real world. In this game, you are not going to play as one of the members of the Ghostbusters, but it became a new member of the Ghostbusters. Your character anonymous, no name, but served as an experimental weapon specialist. That means you'll get new weapons or upgrade the existing weapon capabilities created Egon

Are not for you know Ghostbusters, this group does not destroy the ghost. They just caught him, and put into special containers at their headquarters. Gameplay also follow this rule. You are armed with the main weapon, the proton beam. Your task is to fire a proton beam, tying the "ghost" with its light, weaken them, and dragged them into the trap of the device. This task is not always easy though all members of the Ghostbusters work together to help each other.

Unfortunately, even a ghost who must be captured quite diverse, this rule is not always pleasant. After you upgrade a weapon to maximum, the challenge becomes greatly reduced. For variation, Sierra adding additional tasks, namely to find the item curse. For that, you can take advantage okay (Psycho-Kinetic Energy) Meters to find these objects.

Although the old series, Ghostbusters packaged interesting. Relatively good quality graphics, although the movement of the characters in the cut scene still looks a bit stiff. Praise should be given to the quality of her voice. This game collects the original voice actors from the movie screen as a filler voice. Cast your signature can also be heard again

In addition, fresh touch of humor made him more interesting. This game is suitable for old fans, and perhaps could be another alternative for your son than the characters from the manga and anime

Game Test: Prototype

2009-09-02T19:43:00.002+07:00

The experiment that failed, epidemic, virus, mutant monsters, zombies, and the involvement of the military as a reference standard to create an exciting plot for a game. God knows how many games that adopt this plot, and the prototype is not an exception

This game tells of Alex Mercer, a man who is the object of the experiment failed, actually more accurately called very successful. She has amnesia, so do not remember anything about him. One thing he knows, he has extraordinary abilities. He is as strong as superman. Although it can not fly, she can climb a vertical wall in a far more spectacular than Spiderman. He can jump from a skyscraper without injured. More terrible again, she can devour and absorb the victim's body. After absorbing the victim, she can transform herself into the victim, who has mastered the ability, knowing his memory, and even develop new skills.

The main characters are very superior in Balance should be commensurate with the opposite or at least challenging gameplay. This is where the game feels less creative prototype. To deal with Alex, these games tend to only give the opponent a lot. Gameplay was relatively simple, with a mission that was to the point, like looking for an apartment, to protect someone, absorbing one.

To add variety, deliberately giving Radical Free Roam mode outside the main mission. In this mode, she can find environment particular spot or location to exercise, such as record-breaking time to climb the building. Alex will get the rewards points that experiment could be used to upgrade abilities.

As described above, Alex's ability very much. Not surprisingly, the ability to be upgraded a lot. Unfortunately, this also affects the control. There will be considerable variation buttons to remember. Not enough with that, Alex is also equipped with combo attacks, which could be active only if you find yourself by trying different variations of the attack.

One thing is obvious from the description of the prototype is a very large and so crowded. Impressed with the city landscape in Grand Thef Auto? Save your admiration and try this game. You will be amazed to see how she can run fast through the dozens of people and climbing tall buildings without any frame rate slowdown

Windows Scripting With VBScript

2009-08-31T16:09:00.013+07:00

If it works in Windows operating system environment, the days you will often associated with programs written in Visual Basic

Perhaps the day you use a database application created with the language of Visual Basic / VB.NET, or using the web site programmers work ASP / ASP.NET or loyal user application macro written with VBA (Visual Basic for Application) and if your unlucky day , you are a victim of the virus made with VBScript

Of the various types mentioned Visual Basic, VBScript is a scripting language is readily available and used in the Windows environment. You do not need to install an IDE, compiler, or application specific tools.

About VBScript

Made an initial target of VBScript (and JScript) is for the purposes of web development with a focus on the use of Microsoft Internet Explorer browser, the script was executed from the client side (client side scripting). Until this very day you are still able to insert a VBScript in your website, egg for validation purposes or a particular process on the client side, although the use of JavaScript for the same purposes more popular. This is related to inter-browser compatibility is on average more support JavaScript

But for the use of server side (server side scripting), VBScript never experienced the boom in popularity of the engine Active Server Pages (ASP), followed by the ASP.NET-based. NET Framework

In the Windows desktop environment, VBScript can also be used to create applications that run on Windows Script Host (WSH) Environment, introduced since Windows 98 and because of a scripting language, VBScript does not need to go through the compilation process as when you create an application with VB 6 or VB. NET

You can write a VBScript to stand alone file with extension *. vbs. Maybe a little more similar to batch files (*. bat) that has popular (and still can be used to this day) at the time operating system (DOS) can still be brought in the form of diskettes for measuring only hundreds of kilobytes

But of course, VBScript function is much broader than the batch file. You can use VBScript for Windows and network administration, multimedia, databases, we often do not even hear the virus is made with VBScript. Return a language / tools can be a double-edged sword, used for good or bad thing is a choice.

Scripting language itself may not be able to do many things. Location of the advantages is being able to access objects provided by the host application, in this case the WSH, which consists of WSCRIPT.EXE and CSCRIPT.EXE.WSCRIPT.EXE files used in Windows GUI environment, while CSCRIPT.EXE the command-line environment. You can download the latest WSH on the Microsoft Download Center website, by typing the keyword "Windows Script Host" that produces the following URL http://www.microsoft.com/downloads/en/result.aspx?freetext=windows+script+host&displaylang = stype = en & s_basic.

First Script!

If you ever make a program with VB.NET or earlier versions of Visual Basic, to write a VBScript program will not be much different. But do not worry, if you do not have to know VB, provided a basis program, will not be difficult to understand the workings and VBScript syntax is simple, easy to understand, and modular

To write VBScript, you only need a text editor that produces plain text, such as Notepad. Type the following code and save it with any name with extension *. vbs, for example sample.vbs

dim obj
set obj = CreateObject ( "Wscript.Network")
dim sInfo
sInfo = "Hello World:" & vbCRLF & _
"User Name:" & obj. UserName & vbCRLF & _
"Computer Name:" & obj.ComputerName & vbCRLF

msgBox sInfo
set obj = Nothing

Execution of the program by double click the vbs file. The program above creates an object named obj Wscript.Network, to get the UserName and ComputerName of the system you use, and displays them in the form of Message Box. Simple enough?

Controlling Program Through VBScript

You can call other programs through VBScript. The following simple script will show a similar function when you access the Start menu - Run on Windows.

ask = "Programs that want to run"
title = "VBScript"
default = "Notepad.exe"
answer = InputBox (ask, title, default)
set wshshell = CreateObject ( "WScript.Shell")
wshshell.Run answer

Save the above program code with extension *. vbs and double-click execution. The output from the script will ask what program to run (default is Notepad.exe) you can replace it with another program such examples that will summon msconfig System Configuration Utility, which will call iexplore.exe Internet Explorer browser, and so on.

Not only GUI-based program, you can also run the command line-based program, like the dir command to view a list of files and directories. The following example demonstrates calling the dir command, save results to a text file, and displays them in a pop-up window

Note the use CreateObject ( "Scripting.File-SystemObject") who works for the management of files, such as writing and reading the contents of text files. Output from above program code looks like the following picture

We will go further with the control program more interesting. This time VBScript will call a specific method of the object of Microsoft Word. For example the following program code:

set word = CreateObject ( "Word.Application")
word.documents.Add
checkword = InputBox ( "Enter a word:")
set of suggestions = word.GetSpellingSuggestions (checkword)
if suggestions.Count = 0 then
msgBox "The writing is correct"
else
list = "Writing is suggested:" "" & checkword & "" ":" & vbCr
for each suggestion in suggestion
list = list & suggestion & vbCr
next
msgBox list
end if
word.Quit

When executed, the program will ask you to enter words, then the program will check spelling and suggest the correct word, if the program found a spelling error.

What makes the world interesting programming is creativity, you will quickly feel bored if you do coding without ever thinking to develop what you already know

Similarly, once you learn VBScript ability to control other programs, the implementation of course not limited to the examples given. Developing example, you can create a simple program that when executed will open favorite sites you are, the program code is as follows:

When executed, the script will call the URL which we have defined in the default browser. This simple program can be very useful for those of you who regularly visit certain sites.

Objects Used

Throughout the program examples shown, you already know the various objects such as Scripting.FileSystemObject, WScript.Network, and many other objects that you use the CreateObject command. How to know the objects found on your computer system? A way to see it is to use the Registry Editor.

You can see these objects by running the Registry Editor by typing regedit in the StartMenu, not in HKEY_CLASSES_ROOT, here are stored all the information about file associations and ActiveX objects. For example, you can find WScript.Network, if you do not find it, then the object is not you can use in your computer system

With VBScript, you can search and display all these objects. Program code is as follows:

Note that this program requires regtool.tob object, if not installed, you can search and download on the internet, for example in the URL http://www.filewatcher.com/m/regtool.ocx.22528.0.0.html, this program will displays the number of available objects and displays them on the message box. If necessary, of course, you can make modifications by writing to text files. The output of this program can be seen in the following figure:

VBScript and Security Issues

The more powerful VBScript, such as the ability to access the registry, files, and various objects, can not help but also raises security issues within the Windows operating system itself, for example, if VBScript is used as a destructive exploits by people who are not well-intentioned, and certainly we do not can eliminate the script and malice with sage or call of protest

Knowledge available for anyone to learn, because it was however, able to produce the script through a security hole that proved a good effort (to be not good if used to harm people), will get better if followed by finding ways to prevent it, remember that one of the best protection is to understand the attack came.

Making Linux Server more Secure and Fast

2009-08-19T22:45:00.003+07:00

Once your Linux server is active and operational. And you want to safe as possible. However, what the service should be terminated (permanently) that remain secure and how to stop it? Of course, how to stop a service depends on the distribution you use. Not all the same, but most of the service can be stopped using the init.

On the Ubuntu machine, you can stop the service with the command sudo / etc / init.d / command_line stop. At the Red Hat distribution. You can stop them (as root) with the command / etc / rc.d / init.d / command_name stop. Here are the commands you can use to stop the service which can be dangerous to the security server, so you can more safely.

Sendmail

That we must admitted sendmail unless you know the outside in, then you should not use it. Sendmail has much famous rift security. So soon may stop immediately. Sendmail can be stopped with the command / etc / init.d / sendmail stop. Now if you need a mail server, move to Postfix or other mail daemon that is easily secured and configured

NFS

Do not be wrong. You may use it often, but the NFS daemon vulnerable to exploitation. To stop you must stop the NFS and NFS Portmap. Both can be stopped by using the command / etc / init.d / portmap and / etc / init.d / nfs stop

Chargen

By default this service is not running. However, if you get it running, then it is not good. Chargen is used for test purposes, for example, the bandwidth test. To stop this service, run the command / etc / init.d / stop chargen

Ypbind

This daemon binds NIS clients to NIS domain. If you do not use NIS, this service can be stopped. This service can cause some problems, such as vulnerability when there are some remote connection, memory corruption, and other. To stop the ypbind, run the command / etc / init.d / ypbind stop

Sshd

Many administrators who depend on access to sshd on the remote machine. If you do not do that then it's good not to run the daemon. Although OpenSSH is quite secure, vulnerabilities are still there. If you need to run the sshd daemon, make sure to disable root access first and OpenSSH server always updated with the latest release. To stop the sshd daemon, run the command / etc / init.d / sshd stop

Anacron

Service has one function, namely to run a cron job is scheduled when your system down. First and most important is, your system probably will never be down. Service is not necessary, and like much other service, can be exploited. Stop this service with the command / etc / init.d / anacron stop

ATD

This command control the service at the sort, check, or remove the work will be done next. Many people who do not use the at command, and because of what the ATD can be done by cron, then this service can be stopped. To stop the run ATD command / etc / init.d / stop ATD

Routed

Is the server you need to update routing table automatically? Routing on the Linux system can be well exploited and RIP (the protocol used by routed) does not have any authentication in it. So unless you are using Linux as a router, just stop this service. The command / etc / init.d / routed stop will overcome your problem.

SNMPD

When runs this daemon waiting request SNMP to monitor the system. Usually you do not need this unless you need to monitor a remote server. There is a lot of exploitation in the SNMP out there so you might want to think twice if you want to run it on machines that can be accessed from other places. To stop this daemon, run the command / etc / init.d / snmpd stop

Rsync

You may occasionally use rsync. But, this can be replaced with scp (secure copy of the secure shell) with so many weaknesses rsync, then certainly you need to stop it. By running the command / etc / init.d / rsync stop you can feel safe.

That is the list of services that can be terminated to make Linux more secure server, you may ask how that does not need to re-run all the command and if in fact you have to re-boot. On the Ubuntu machine, you can run the command sudo update-rc.d-f remove APPNAME (which is the name of the service APPNAME that removed) that would remove the service from the process of booting

On the Fedora machine, you can run the tool using the Services ) in the service who do not want to run, thenGUI, remove the check ( saved. Or you can use the ntsysv. With ntsysv, you can find the service that is run when booting, select, and press space to stop the service (service that has run the star) and then exit the application. In addition to more secure, the less the service is run when booting, it will be faster to boot your machine. So stopping the service does not need is a win-win solution.

How to Easy Handle on Linux Network

2009-08-18T14:41:00.006+07:00

We see how the ease of handling Linux network. You never know when need to use the command line or when the need to support graphical interface to iptables

Network now has become a need. Whether in the home or corporate environment, the network is one aspect to computing, without a doubt, necessary to perform the work. And with some help, operating system Linux can be a king of the network, both in terms of ease of use and security. However, that does not mean that the user level (and sometimes even users who are experts) do not need some assistance. Following tips will make your Linux network a bit more smoothly.

Take advantage of the file / etc / hosts

File is used to host a static host name and is a quick way to create a network shortcut. One of the first things you must do in the Linux machine is a machine to enter a different file / etc / hosts. Thus, you do not have to type the IP address. Writing on the file format is IP_ADDRESS NICKNAME. For example, if you perform backups on the machine with the IP address 192.19.1.1 enter: 192.168.1.1 backup. Now if you want to connect to the machine, for example by using the secure shell, you can just type ssh-v-l username backup

Keep the Unwanted Users with / etc / hosts.deny

File "host" who is helping hosts.deny file. With this file, you can control access based on client or server name. This is useful in many situations. You can block a domain that is in the blacklist so it will not be able to access your network or you can block that particular user can not access a machine. But however you use it, the format remains the same. Suppose, you want to block domain bad.domain.name. To do so, open the file / etc / hosts.deny (you'll need root permissions or sudo) and add: ALL: bad.domain.name

Use WICD to Handle Wireless Network

Linux has long experience with the major wireless networks. However, it has become the past. With the current distribution, detection wireless card is no longer difficult, The problem now is the encryption. Many of the Linux wireless tools have problems when encryption is used. However, WICD tool can overcome this. Now, connect to a wireless network encryption in WPA or WPA2 with no difficulty. Use WICD to reduce the difficulty you.

Download and Install Interface for iptables

Do not assume that just because using Linux, then you are safe. You still need some security. And the best security on Linux is iptables. The only problem with iptables is rather difficult (especially for new users) fortunately, there is a graphical interface to iptables. One of the best is a firestarter. Interface makes use iptables to be easy, so you do not spend more security because only lazy learning

Identify the Command-Line Tool

Must be admitted that if we use Linux, then a certain time you need to restart the network and does not have access to the GUI. In this case, the command / etc / rc.d / network restart will overcome your problem. Of course, it is not the only tool command-line network. You also need to know tools like dhclient, traceroute, samba, ping, and netstat.

Enter the DNS Server Direct Address

You may have experienced network problems that caused the loss of DNS server address. For that, enter the DNS server address directly to the file / etc / resolve.conf. The format is as follows: nameserver IP_ADDRESS, where IP_ADDRESS is the IP address of your DNS server. You can enter the DNS server as much as possible.

Antivirus Installation

If you run a mail server, and then have an antivirus is a must. While you are running Linux and your mail server 99.99% immune to the virus, it does not mean that the entire client download from the mail server you are also immune. Thus, the administrative tasks you will be much easier if you install antivirus like ClamAV, for example, to your Linux mail server. He will give you security and tranquility that is so your users stay safe.

Know How to configure the IP Address Manually

It is true, there are GUI tools to do this properly and also all the tool works very well. However, as the later you feel if it is long enough to set up operating system, no one has the tool to do the work in the reserve. One of the best backup tools in managing the network is the Linux command ipconfig. In addition to display the network card information, you can use the ipconfig command to configure the network card manually. This is done as follows:

/ sbin / ifconfig eth0 192.168.1.1 netmask 255.255.255.0 broadcast 192.168.1.255

Identify the file / etc / interfaces (Ubuntu) or / etc / sysconfig / network-scripts (Red Hat / Fedora)

This file contains information about the network card. As you can see in the image example, all interfaces in the set up for dhcp. If you are floating, the dhcp is required. However, what if you use the interface only in one location? For that, you can configure a permanent basis.

Does not Forget When set smbpasswd Samba

When the client or phone that comes with Samba as difficulty, it is usually because the username and password they have not been included with smbpasswd. If not done, then the user will not be able to perform authentication with the Samba server. When using smbpasswd to enter a new user, do not forget to use a switch-as follows: smbpasswd-a USERNAME. After pressing [Enter] you will be prompted to enter a user password. Note: you must have access to root (or sudo) to do this.

Understanding Silverlight

2009-08-17T22:14:00.012+07:00

Silverlight to bring rich Internet application on your website

Sounds interesting, but what is rich internet application? is a simple web application that has the characteristics such as desktop applications, can display animation, video graphics and audio. indeed, it is not ideal and it is not something new as well. We already have the current Adobe Flash and Microsoft Silverlight

Silverlight

Silverlight is a plugin in the browser, meaning you must install the Silverlight runtime on the client side as you, so you can access the features on the Silverlight web browser. Silverlight is used in the Windows operating system and Mac OS X. For the operating system Linux, developed by the Mono Project, although until now not include Moonlight overall features of the Silverlight

Currently, Silverlight has reached version 3.0 beta, since the initial release in 2007. While the still new, the implementation of Silverlight has been found on the website, great website. For example, such as http://memoribilia.hardrock.com the features to zoom in and zoom out images with high resolution (also called the DeepZoom) does not cause the image to be broken even if you do zoom in the picture with the extreme

This can be done only because the Silverlight download in the image and the resolution of the current views, although this technique speed loading time compared to downloading the entire image with high resolution, but for those of you who have internet connections, which are relatively less fast, less comfortable to enjoy this feature , although on further explanation, you will know the actual Silverlight Technology has been the process of minimizing the burden on the server.

Another example implementation of Silverlight you can see on the website that uses Silverlight http://www.popfly.com for various games. To identify the Silverlight application, you can right-click on the area that will display the application menu Silverlight, Flash is similar to the first known.

Examples of other web applications using Silverlight can be seen in the URL http://silverlight.net/showcase

Development Tools

Silverlight application consists of a text file, so it can be written with any text editor. For the development of a larger scale, you can write Silverlight applications with language-based program. NET, along with the development. NET Framework stabile release at this time has reached version 3.5 (. NET Framework 4.0 is still in beta version) However, to install. NET Framework is not mandatory, because the plugin Silverlight download works with the library-the library needs

To make user interface design, you can also use Microsoft Expression Blend, which support text engine WPF (Windows Presentation Foundation) is able to produce typography ClearType and OpenType also supports vector-based 2D and 3D with hardware acceleration via DirectX

If you often work with ASP.NET, Silverlight using designed in the same paradigm. But there is a different process when the application is running. On ASP.NET, you certainly understand that the process is located on the main server, and the pages requested in the client. On Silverlight, is located on the main client, even though the client still interacts with the server to request the necessary data. This is one of the purposes Silverlight plugin, which served as a platform on the client application.

For development purposes, you also need the Microsoft Silverlight SDK at the URL http://silverlight.net (DOWNLOAD) Silverlight SDK provides component, utility, and documentation

XAML

Each programmers will be familiar with Silverlight XAML (extensible Application Markup Language) XML-based XAML (Extensible Markup Language), by Microsoft as the author, as directed XAML markup language for defining user interface elements, data binding, event, and other features. Even in Windows Workflow Foundation, XAML can be used to define the Workflow.

To better understand it, make a simple program, create a folder to hold files that are required, make sure the folder is accessible via HTTP, you can use the web server Apache or IIS

Create a simple XAML file as follows:

Save this code with a name that is easily understood, for example myUI.xaml. This code will write "Learning Silverlight" in the web browser, but not necessarily can be called through a web browser, you must call through the HTML / JavaScript as follows:

Save the file, for example with the name index.html. Attention the following lines:

The base contains the instructions to call Silverlight.js file that is located in the same folder where the file Silverlight.js you get? If you've installed Silverlight plugin (Silverlight.2.0.exe) (DOWNLOAD) and the Silverlight SDK (Silverlight_sdk.exe) (DOWNLOAD), the file is located on the Silverlight.js folder C: \ Program Files \ Microsoft SDKs \ Silverlight \ v3.0 \ Tools, copy into the same folder with the index.html. Then you can call the index.html in a browser through HTTP

Not easy enough? File Silverlight.js functions as the library must be included, the file index.html to function as the page field, and myUI.xaml file contains the user interface to display.

Of course, not only that Silverlight can do, change the file myUI.xaml into the following program code:

Glimpse the line-line program, you can certainly guess that will be shown is the form of a square. Speciality can appear with the color gradation.

Animation

Start a new internet is known knowledgeable, very rare form of we see a smooth animation, is quite happy if you have a website with animated text to run through the resulting HTML tag (marquee), add in a little animated GIF images (which it frame very few) But how then appear -a new way to use JavaScript, DHTML, and Dom (Document Object Model) Since start Flash is often used, Isn’t animation, making games on the website is common.

As a technology-which is called as a Flash competitor, Silverlight is certainly has a similar ability. One way to display animation effects, is to use a Storyboard object

Storyboard main structure is as follows:

The above code contains instructions to run the animation on the object named object1, Form attribute = "50" To "200" means the width of object1 from 50 to 200, the attribute Duration = "0:0:5" means that the animation is run in time 5 seconds (using the format hh: mm: ss)

Silverlight is still a lot of interesting discussion, but with a basic understanding and a few examples given in this article, you will not be expected to have difficulty means to delve further

One thing to be interesting, rich internet application when trying to create a web application does not lose out with desktop applications, the consequences that occur is increasing the burden on the client, this is not happening on Silverlight, but we already met with the need to install the Flash plugin, or Java Runtime on the web application that uses Java. Although it must be recognized, progress in hardware specifications to make public a client computer at this time may in the same level or better specifications than the server computer 10 years ago. In addition, the Internet is also able to support efforts to overcome the burden of the excess with only download the required libraries, or other techniques.

But of course, there are some cases that is different and there is no one solution to all problems. For any case related to information technology, understanding the various solutions in the midst of technological progress in different sectors is important, but the new meaning when you are able to choose the best solution, according to the situation and condition you.

INTERACTIVE WEB WITH JQUERY

2009-08-16T15:03:00.016+07:00

Web development has experienced a rapid development, the website becomes more interactive, are you ready to follow it?

As the fashion world that always switch mode, the display continues to update the website with a new face. Although there must be a significant change, but can be engaging and make another website to follow.

For example, look at the website-the website of the leading search functionality, including an amazon.com, wikipedia.org, or search engines such as google.com, yahoo.com, and so on. What similarity? In fact everything is using autosuggest (often called AutoComplete) may suggest an alternative keyword for visitors.

Autosuggest only one example of how websites appear more rich improvisation, friendly and interactive. Behind all that, there is a code that is quite complex. But if you understand the jQuery code, complex code can be display simple.

Overview of jQuery

Until this article was written, the jQuery address in http://jquery.com turn has been the age of 3 years. However, jQuery is not actually a new thing to see if all that is therein, because a function written in JavaScript, and JavaScript itself was introduced by Netscape in 1995.

jQuery offers modern features that is ready to use, although the idea is to create a simple JavaScript library, jQuery was able to attract large companies to the jQuery in bundling products. Nokia will integrate jQuery into a web platform Run-Time and Microsoft to adopt jQuery in Visual Studio

In addition, Google also provides a host for the special jQuery to be able to directly access the free, jQuery also received support from various parties that make a variety of additional plugins.

Using jQuery it is easy, you need is a download file on the jQuery http://jquery.com, the latest version, this time it is up to version 1.3.2 with the name of the file jquery-1.3.2.min.js. Size is also small enough to a library of powerful, only about 56 kilobytes, and the only reason that you need. JavaScript file has functions Ajax, Dom (Document Object Mode), Event, and the various effects that are prepared by the web developer.

For ease of use, you can change the file jquery-1.3.2.min.js become jquery.js it, and paste them on the program code (HTML / PHP / ASP and so on) as follows:

Path lib / jQuery.js shows the location of the file jQuery.js. Because jQuery is a JavaScript library, especially the web developer just need to deepen knowledge of JavaScript, and jQuery also can be used by web designers that deepens CSS (Cascading Style Sheets) language does not have a program that new, but many new things that can be created on your website.

For web developers who will use the new jQuery, it's easier to understand the principles basically see the first example the case of using the HTML / CSS is static, and therefore does not need to be with the server side scripting such as PHP and so on, also do not need to do database operations.

Once you understand how jQuery works, you can easily implementing into a dynamic website

Some examples below will introduce you to the jQuery code in HTML / CSS is simple, and then can easily be developed based on the needs of your website.

CSS Controls

With jQuery, you can control the CSS used. First look at the following simple code, in it you can see there is HTML code, CSS and JavaScript / jQuery.

If you save this code in an HTML file (like index.html) and run in a browser, will be in a different view. Now let us study how collaboration jQuery and CSS can produce this effect. Note the following JavaScript:

Command $ (document). Ready (function () is a command to run the code below when the document is ready, or are ready with the event. If the documents have been completed in the load, the line $ ( "p: last"). AddClass ( " selected highlight "); will run. This code is called to add class and highlights the selected element p: last. That is, class-the class will be executed for the new tag

last. Next, the following code defines a CSS class with a defined above:

Tags

last in the index.html is

Rocks!

, So any posts will appear in accordance with the class that has been defined. From this example, you certainly have started to understand the flow of jQuery. New things that you may find is the use of symbols such as $ on:

$ (Document). ready (function ()

$ Alias is a symbol of the jQuery namespace, which can also be written:

jQuery (document). ready (function ()

Therefore, you will find the use of the symbol $ in use jQuery

The Elegant Read More

Sure you visit the website or blog that has the article. Because, in general, the article consists of several paragraphs, it will usually be shown first paragraph beginning, and the key is available / link as "read more" if you click on will lead you to the article or the entire paragraph, complete with the process and call the page refresh other.

In the example of this, we will create more articles that may appear on the same page, without a refresh, even accompanied by animation. Do not imagine a complex code, just like this:

Full paragraph will be displayed if you click the button "Read More" nearly no new things here, unless the use of show and hide function, the parameters have the time to animation. For example the line:

Slide Panel

Previously only a few alternatives if you want to divide a page into several separate parts, for example, by using the table or frame, and everything seemed rigid.

With jQuery, you can create a slide bar with easy, and certainly does not seem as rigid panel is able to move with a smooth animation. Note the following code:

If you already understand the previous examples, you certainly do not have difficulties to understand this example slide panel. The only new function or command is located on the line $ ( "# panel"). SlideToggle ( "slow") that call the function slideToggle provided jQuery

Ajax with jQuery

One of the purposes is to support jQuery AJAX techniques (Asynchronous JavaScript and XML) is a web application to take data from the server and work in the background so it does not display the web page subject. In this case, jQuery generally used by more designers than programmers, as Ajax to the server, which means the server must use the side scripting / programming

Using the jQuery Ajax in the nick does not differ from the examples already described, there is a difference only PHP files (or other server side scripting) Here is an example of Ajax to display a quote at random, there is a index.html file as follows:

Note on the line $ ( "# quote p"). Load ( "quote.php) where the jQuery element id =" quote "that contain content that is produced by quote.php.

Quote.php itself contains a simple PHP code as follows:

Function quote.php makes only a number, where number is used as the array index variable $ quote, which is then displayed. Of course, you can make further modifications, for example, take the content from the database.

Click and Drag

The past may not be a website page can be very interactive so that the withdrawal has the ability desktop applications, for example, have the ability to click and drag, resize, progress bars, and various effects and smooth animation.

Many developed based jQuery plugins and libraries that have different features and can be integrated on your website. One of them is the User Interface library jQuery or jQuery UI in the address http://jqueryui.com

Write Less, Do More

JQuery is not excessive if it has the slogan "Write Less, Do More" shows a lot of things we can do with only a few of the writing code. If JavaScript is considered only the expertise of web developers, but with jQuery has a way of writing JavaScript easier, create a web designer can use jQuery to need.

Grid Service

2009-08-13T15:51:00.003+07:00

Grid Service

Interoperability between applications in small scale can meet with the Web Service. Development of large-scale computing introduce a Grid-based Grid Service

Information technology has become a prime mover in many fields of work. Various information system developed to facilitate the management of data using a computer. Initially these systems are sectoral, covering a particular field, but with the growing knowledge of the domain, then the required information system that is cross-sectoral. Brings together many sources of information it is not easy, considering the diversity of components involved, with the standardization of the different. Needed a data interoperability solutions using the latest technology available to many.

Data interoperability

Interoperability in the computer IEEE standard dictionary is defined as the ability of two or more systems for the mutual exchange of data or information and each other can take the data or information is exchanged. Technically, interoperability is declared when the exchange of electronic information and services across the system has held a coherent, involving the electronic system that supported the process of inter-agency or inter-party.

Interoperability is not simply understood as the preparation by a central organization that works to facilitate, instruct the system specification and process raw materials, but it is a consensus with the implementation of the framework (framework) that has been set. By applying the framework, each institution will be authorized to make decisions related to selecting hardware and software solutions. Real conditions in the field generally indicates that the information systems used in the various institutions built on the components is different. Heterogeneities occur in hardware, operating system, application programs, system and database used

Web Service

Web Service is a software system designed to support interoperability machine to machine interaction over a network computer. Have interface with a format that can be processed by machines, especially the Web Service Definition Language (WSDL) Web Service uses a system of standards which are applicable in the web, for example, messages using the SOAP (Simple Object Access Protocol) and delivered through the HTTP protocol

Next stages of the Web Service:

1. Search for Web Service that has the desired service with the Universal Description Discovery and Integration (UDDI) registry
2. UDDI registry will be a server which provides the service.
3. Ask the Web server in the Service how to use the service
4. Web Service will be in the WSDL
5. Request a service performed using the SOAP format
6. Web Service will request the SOAP format

Address Web Service form of URI (Uniform Resource Identifier) or also known as URL (Uniform Resource Locator), for example, http://ws.mysite.com/MathService. This like not access the web through a browser, only Web Service is for the target machine. The advantage of the web is also inherent in the Web Service, such as platform-independent and can pass the firewall

Programme for Web Service applications, both on the client and server, using more automation in creating Stub SOAP and WSDL. Program process and answers the request in SOAP format automatically. Next step by step description

1. When the client application to use the Web Service client Stub will called, which then form the appropriate SOAP request. This is called the process of (marshalling) or continuation (serializing)
2. SOAP request is sent through the network with the HTTP protocol, Web Service received and forwarded to the server Stub. Then the server SOAP Stub will translate into something understandable by the implementation of the service. This is referred to as the demolition process (unmarshalling) or decomposition (deserializing)
3. Implementation of the service receives the request and perform the required work in accordance
4. Results of operations and then forwarded to the server Stub, which is changed to answer in SOAP format
5. Best SOAP sent through this network with the HTTP protocol, the client received Stub and changed into something understandable by the application
6. Finally the application receives the results and use the Web Service

Grid Computing

Grid computing technology is a way combining the resources of the many computers that are connected in a network so that the form of a computer system unit, the source of large computing power. Grid computing emphasizes the coordination of resources and problem-solving in dynamic, virtual organizations in multiinstitusional. The key concept is the ability to negotiating with the resources between the parties involved (providers and users) and use it for a purpose.

Grid computing infrastructure, built with combining Grid systems that are in the various institutions into one entity. Hardware and software configuration of each system can vary, but with Grid computing technology to operate as the Globus Toolkit 4 (GT4) on the twist-the twist, the whole system formed a unity Grid computing infrastructure. Users in an institution can take advantage of computing resources that are outside the institution.

Standards Grid system architecture in the Open Grid Service Architecture (OGSA). OGSA defines the mechanisms to create, manage, and exchange information between Grid Service, using the concept of technology and Web Service. Most of the convention is a product of OGSA Grid community, especially the Globus Alliance, and became the main topic in the Global Grid Forum. Since rising Globus Toolkit 3, Globus Project offers a collection of open source Grid Service that follows the OGSA architectural principles.

Grid Service

Grid Service is a Web Service that provides a set of interface definitions and following the convention set. Grid Service to add what is not available in the Web Service and is required in the spread or Grid computing. Specifically, naming service, minimum service capabilities, and services development (Stateful). Although it can use the same ways that other, but the uniformity and consistency are essential so that the more parties that may be involved.

Improvement of the Grid Service introduced the Open Grid Service Infrastructure (OGSI) can be divided into seven things like the following:

1. Stateful and transient services. Contrary to the Web Service is not considering the circumstances (stateless), Grid Service has given the ability of each operation performed. Thus, the operation can be done in sequence, in which the results of operations are one of the parameters for the next operation. Grid service can also be temporary (transient), where the service was created in the course as needed. This approach is called the factory / instance. In this way, each user works on each instance, which can also share with other users. Life cycle of the service or the instance can be specified by the user, and can be destroyed after use.
2. Lifecycle management. With model factory / instance above, the required life cycle management in the Grid Service. OGSI provides only basic understanding of this mechanism, which can be developed in the implementation of information, such as the Globus Toolkit 3 (GT3)
3. Data Service. Additional data service allows presenting the data on each service, which can be accessed directly through the interface. When the Web Service provides the only operations in the WSDL interface, service data can be viewed as attributes that describe these operations. In general there are two service categories of data: a) information circumstances, such as operating results, while the results, and runtime information; b) metadata information, such as data system, interfaces is supported, and the cost of service.
4. Notifications. Grid Service notice features (notification) event, which can be set as a source or as a customer (sinks). If a change occurs in the Service Grid, this incident will be reported to each customer. Not all incidents were reported, only the desired by the Grid Service.
5. Service Groups. Each service can be arranged to apply as a service group, which is a collection of various services. There are operations for this, such as add and remove from the service group, and search service that complies with certain conditions. Implementation of GT3 in the service group allows combining much different service and accesses it through a street entrance.
6. portType extension. When the Web Service only supports 1 portType defined in the WSDL interface, Grid Service portType supports the expansion of existing ones to facilitate in the development of the new portType.
7. GSH and GSR Service Handle (GSH) is the address of a Grid Service (a URI) and are unique. GSH only show where the Grid Service, but does not provide information on how to communicate with the Grid Service. This is required for the purposes of the Grid Service Reference (GSR) user translate into GSH GSR with HandleResolver call on the Grid Service. Generally, communication with the Grid Service using SOAP, so that the form of GSR WSDL file. Sample XML definition of the GSR and GSH OGSI as below:

OGSA Data Access & Integration (DAI)

One of the application of Grid Services for data access and integration to the database is OGSA-DAI. Via OGSA-DAI, data sources and a separate power source and a variety of services may be available as a fully integrated service with other OGSA. Therefore, the OGSA-DAI provide a basis for the service operation on the layer above it, thereby providing greater functionality such as data federation and query spread.

In the database query, provided Grid Data Service (GDS), a document-oriented interface, containing activities related to each other, operated on for a time and get results. This activity may consist of various activities, such as sqlQueryStatement, xslTransform, and deliverTOGFTP. This activity can be created and registered on the system. Activity formatted XML document, such as the example below

OGSA-DAI has three main interfaces, the Grid Data Service Registry (GDSR), Grid Data Service Factory (GDSF) and Grid Data Service (GDS). Series of actions undertaken OGSA-DAI client of OGSA-DAI server, namely:

1. Communicate with the registry (GDSR) and request the handle of GDSF
2. Call the factory (GDSF) and then create a handle of GDS
3. GDS call and send the request in a document the operation, which was then done by GDS in the form of a query in the database, and return the results to the user.

Standardization of data access with the OGSA-DAI can be further expanded into other Grid Service, such as the OGSA Distributed Query Processor (DQP). OGSA-DQP aim to query and analyze data on the Grid system and the parallel spread. OGSA-DQP is made up of two components, namely the coordinator and evaluator. Coordination as a user to send commands and query plan, while the evaluator function to perform a query plan.

Working With Support From Microblogging?

2009-08-12T18:23:00.005+07:00

There are many online tools that can simplify the way we interact with colleagues in a way that is productive, whether paid or not.

Title above is not intended to be the overall topic of this paper. But from an experience and any posts of some information technology professionals on the internet, microblogging tools like Twitter and Plurk, it appeared that not only can be used to socializing with friends, colleagues, etc. But can also be used to support the productivity of our day-to-day at the office

Work Experience

Some time ago, we had time to get a job abroad to work as part of a team in tugasi to prepare a tender proposal. We joined the team when the progress of the preparation of the proposal has reached about 30 to 40 percent. Be practical already roughly in the middle of the process. However, important components of the proposal is not fully ready. Sheet Statement of Compliance, the statement of the participants in the tender akan capabilities fulfill all requirements of the tender organizer (the client). In addition, nearly all the cost components also can not tender difinalisasi. And the time remaining is just to stay 2 weeks.

Solutions offered by the company are very varied. Company to prepare all the infrastructure solutions, including dozens of blade servers, as well as online and offline storage. Similarly, the software, is a coincidence that the core of the solution required by the client. That is, a set of software-based information technology service management. This solution is also equipped with a hardware implementation services and software, plus the outsourcing solutions in a period of 3 years. Can be, so that the client seeks the solution that they need is based outsourcing, so the cost of their monthly pay is the cost of which is the Operational Expenditure (OpEx) and that there are no capital at all costs.

Online Tools

To be able to complete the proposal with both, we are charged as accidental bid manager should be able to work with, at least, four different business units in the company, they are:

1. Business units that work in the field of hardware, servers and storage for
2. Business units that work in the field of software, software for information technology service management
3. Business units that work in the field of consultancy and systems integrator
4. Business units that work in the field of service outsourcing.

And to make the problem more complicated, each team member in the unit was also at work in four or five other activities in parallel. Multitasking is not avoided.

Tender proposal preparation activities are activities that are solid akan collaboration and exchange of written information. Verbal information is not enough. For example, the chapter on the proposal of technical information, there are at least 6 technical consultant who must complete this section. All changes must go through approval process before the document version of the proposal can be changed.

Similarly, updates prices, both from the hardware, software, services mapun-related services, from the minute-minute submission before the process continues to change. Given the total price of the early versions are still on the three-fold greater than the value that is estimated will be received by the client. Very day, and changes should always be noted, to see how big the contribution and seriousness of each business unit in the overall total price.

Also add complexity in the minimal time that can be agreed upon by each team member to be able to physically sit in a room together. Agreement can only be done to meet within 2 hours every 2 days. In fact the interaction is needed more than that. In many cases, almost every time there will be interaction.

To be able to overcome it all, the company operates a variety of online tools. One that is not foreign to us is to use Microsoft SharePoint site online, where as an online document collaboration. In addition, use Microsoft Office Communicator, as a substitute for public instant messaging.

Use Microsoft Office Outlook are very diminimalisasi, considering collaborating with the Outlook was not very effective. Imagine if you work 4 or 5 on the implementation of the project at a time, where you must interact with a total of 20-30 different people, not to mention the exchange of documents that eating at least 2-5 MB of space. Thus, it can be growing your Outlook database, not to mention the effectiveness of your working time is reduced because the remote must continue to change the concentration of the one topic to another topic. However, Outlook is still used for the exchange of information in which a record in writing and, if necessary interaction with external parties the company is required.

And there is another online tool that is used effectively here. Believe it or not, we use Plurk as a status update notes.

Microsoft SharePoint

This tool is no longer a strange thing for most people, the first we have to do is access the site's Employee Self-Service and select the SharePoint services. At the initial stage, we must determine whether the site will be accessed only by internal company or of those who are outside the company. Choice of course is the internal company. The next step is relatively simple, which is preparing the list and determine the user group access rights based on the read and write in the site.

We then create special folders for the various types of documents that will be used to collaborate. Example of the folders are:

1. Requirement Documents. Is the folder where the invitation and tender documents belonging to the client related documents are stored as a reference.
2. Proposal Template. Folder is prepared for storage proposal template that can be used by all members of the team will prepare the proposal
3. Proposal Documents. Folder is a proposal to save the latest version of the document, in it there is also a sub-folder for earlier versions.
4. Statement of Compliance. Is the folder in which each team member can give opinions or save documents, records relating to the suitability of the solution to the needs of clients
5. Pricing Information. Is the folder where to store price information of each business unit or from external parties.
6. Minutes of the Meeting. Is the folder where all the documents in the results of the meeting record. Here, we also save an excel file to monitor all action items generated in the meeting. What's the problem, agents who, and when the deadline
7. Micellaneous items. Is a folder to store the various documents such as brochures related products and services

We also synchronize the document which is in the hard drive with the site in SharePoint through features available in Microsoft Outlook. This is easier for us to work offline if you're not in the office.

With Microsoft SharePoint, Outlook database each team member will not "explode" because dozens of e-mail attachment with a minimum size of 1 MB to the top. With a little configuration in Outlook, any changes or updates to the documents that are in the folder in the Microsoft SharePoint can quickly known by every team member.

Microsoft Office Communicator

It is the suggestion, although not prohibited, the company not to use public instant messaging. And instead, the company's Microsoft Office Communicator services to simplify the communication between workers, whether a separate location work.

We are involved in the preparation of this proposal using the Office Communicator extensively, both to share information and non-formal simply knowing "the existence of the" opposite speech.

Integration of out-of-the-box (OOB) between Office Communicator Outlook ease with each team member, the status of the opponent speaks, whether currently available or are in a meeting. Similarly, when a member sends an email it is important to one or more recipients. Then use Office Communicator, the recipient can immediately initiate a chat session with the sender. This can easily be done on the interface because the e-mail, online status (in the form of the ball image colors) from each sender and recipient can be directly known.

Not infrequently, when we receive an important e-mail, we immediately initiated a chat session with the sender to multiple recipients at once memverivikasi content of e-mail that is sent. If there is a need to update and then, the sender will send a return e-mail containing the update.

However iplementasi integration of Office Communicator with the IP-based phone line still has not been done in our company, so that the implementation of the concept of unified communication still can not fully done.

With Office Communicator, the number of e-mail was sent or received by each team member also can be significantly reduced. An e-mail threed can consist of dozens of e-mail replies, but the implementation of this feature, can contain a sufficient threed four or five replies only.

PLURK

Belive it or not, almost all the team members using Plurk as a media to update the status of their activities. It is not everything, but all members of a technical team to use it.

Plurk - www.plurk.com is an online site that allows users to be able to "announce" the status of activities or day-to-day users. Whatever can be written, there is no limit. Plurk is a big part of the internet revolution that is currently happening online, the online social networking, or banya buzzed as the Web 2.0 wave. Plurk give permission to write to update his user associated with events, feelings and so forth, the user experience or feel in 140 characters. Or in terms populernya is microblogging. And it again, it's all arranged in a timeline of interesting

Plurk is used by most members of the team because it can give incentive to check the status of other team members. Does not mean that Office Communicator can not do so. But, Plurk provide the flexibility to update the form to 140 characters, which of course is less well seen when using Office Communicator. And features of the Plurk timeline is not replaceable.

As a manager in the bid preparation process of this proposal, we repeatedly feel need to get the status of jobs as a result of the action items in each meeting. In many instances, we do not need to lift the phone and pressing the buttons of the extension member of the team, but enough to open the account Plurk to view the status of each team member.

The same we do for ourselves, When we're working on a part of the proposal, the status Plurk, we make updates such as "Jimmy is working on Section 2.2 of XXXX's proposal" It is easier for people to check the work done by us. So anyone who is concerned for the same proposal in the know who can do that.

Recommended timeline will be very useful to check who is working on a particular proposal section and whether he was and when it is finished. With Plurk, we simply move the timeline in the Plurk user interface. If we have found the name of the team members who want to know our status, then the next step is to check timeline and when he completed the proposal. If you have, then we can also know the exact time when it is complete.

Purposes other Plurk avoid someone is working on a proposal for the same. In the team, it should only have one person as a drafter and as the other reviewer. Before of us in working on a proposal, then we will check the first Plurk account.

Plurk is not without weaknesses, in addition to features that are useful, there are things that need to be a user in utilizing Plurk sites or other online social networking to assist in the process of work. Here are some tips that can give us:

1. Create an account separate from personal account
2. Create a group is closed, where there are only readers and members of the team
3. All states must be in the settings so that only readers and team members who can read it.
4. Of course, use a password that is not easy to guess.

Corporate Use Microblogging

Microblogging in the use of corporate indeed have been a lot done. In fact, in many cases, ats various information security reasons, this activity is not advisable and even forbidden to be done. Imagine if you work at a distributor of products, information technology, in which at a time you update your status: "Jimmy is working on a IT Asset Management solution for budgetary purposes" What will happen if your friend a chance to work in a company competitors know about it?

However, in a closed environment or closed environment, microblogging many predicted would reach a stage of corporate utilization is very high. One example is our experience at the top. Where between the team members, microblogging is used as a tool monitors the status of each member, by minimizing the time that direct interaction sometimes will eat a big cost. Fellow team members can undertake activities in other members of a simple interface, and can quickly take a decision immediately or further activity is important.

In other cases, cooperation between teams such as the above can also be realized in the form of operational activities of Data Center, an incident troubleshooting, application development and process of change in business applications.

Status of a worker, for example: "Alex is working on Server abcde for critical OS patches, updates are expected to be installed on 15:00 pm" can potentially prevent the disruption or incident that may occur with the other workers who logon to the server in the same then make changes to the applications that reside on the server. And of course, make this work, the status can not be directly "notify" the manager, that you are indeed working.

However, the use of microblogging as a corporate tool, still needs to be more, both in terms of effectiveness and penggunannya role in improving workplace productivity. See the potential of microblogging that is big, if its use in the company's corporate stay waiting for the right time.

New Autoit: Debug Mode!

2009-08-11T16:43:00.004+07:00

The virus is always ranks 10 most popular of the virus, even in the big 3 a few months back. How new variants in action? Follow this following discription

Virus-like folder icon with the standard Windows default this is the older players in the world of viruses. Variannya very much, and comes with a variety of sizes. Of the first characteristics that never change is the use of a folder icon with the aim to deceive users. Antivirus others have to recognize that Autoit virus with a lmaut, Sohaned, or YahLover, known as our own Autoit.EE

What Is Autoit ?

Alleged that the author himself called Nhatquanglan the most likely came from Thailand. But we are not sure whether the new variants also come from the same manufacturer. For those of you who have never know what it is to Autoit. Autoit or full Autoit Script, is also the name of the applications that use automation to create a script, exactly automation, hotkeys, and scripting, as written in the site. In short, the script will be in autoit to compile into an executable file

Technically, each pogram made using Autoit Script, there will be a sign pengenalnya. A header or autoit script is usually found in the section final executable file, or sometimes also as an overlay, in hexadecimal 0xA3, 0x48, 0xBE, 0x98, 0x6C, 0x4A, 0xA9, 0x99, 0x4C, 0x53, 0x86, 0xD6, 0x48, 0x7D

Func Main()

After the decompile, we will be able to see the original script virus. Not difficult to learn the script, almost similar to VBScript. Script virus itself from a lot of function such as INSTALL, CREATEINI, UPDATE, and so forth. To make it easier to function main() entrypoint which is a virus

Func Install()

When executed the virus, before it will check the existence of the self in memory. If there is, he will immediately exit. If the victim adalahWindows Vista OS, the virus will copy itself to the Desktop, but if not, the virus will copy the Windows and System32 directory with the name gphone.exe. If the file name already exists, the old file will be delete and replace with a new file. This enables the virus to keep up to date. In the System32 directory it also places a file with the name autorun.ini,. which later was to be placed on removable disk devices such as flash. Do not forget mother is given a file system and hidden attributes.

Action for the next virus DISABLEWINAPPS this function call () which disable Folder Options, Task Manager and regedit. Then meregistrasikan himself on WinLogon shell and the HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Run with the name "Yahoo Messengger" To be able to start running automatically when Windows.

This, the old file will be rename in the setting. ini.old. Settings file ini. saves the configuration file to download the core and are given attributes readonly, hidden, and system. From the download link provided by the file settings.ini., this virus will attempt to download a virus file and replace the old with the new. But until now, update all the links are not accessible anymore.

Then, the virus will add the ID Y! Its M "rnd009" to the list, contact list Y! M victims of course without the user concerned.

Then the virus will make setting the status of Y! M to "View my webcam (private) download_link_virus%%" in that if akan click url address to the virus file. And now the time to spread itself via Y!
