IBM WebSphere Application Server: Administration Tools
by
Steve Robinson | September 2011 | Enterprise Articles IBM
WebSphere Application Server, often referred to simply as WAS, is a JEE-compliant application server platform. JEE stands for Java Enterprise Edition and was previously referred to as J2EE.

Microsoft LightSwitch: Querying and Filtering Data
by
Jayaram Krishnaswamy | September 2011 | Enterprise Articles Microsoft
The logic tier of LightSwitch basically starts with a data service that encapsulates all the access to the data source. This tier can host any number of data services exposed as endpoints at the service boundary. Each data service exposes a number of queryable entity sets with operations for querying entities and an operation for submitting changes; add, update, and delete. An entity set contains entities of the same entity type. All operations take place with entity sets whether they are intended for fetching or for making changes to them. If you think of an entity set as an analogue of SQL table you will not be wrong. Just like you take information out of the table, make changes to it and return it to the table, you do likewise with entity sets.
In this article by Jayaram Krishnaswamy, author of Microsoft Visual Studio LightSwitch Business Application Development, we will take a look at querying a single entity.

by
Jayaram Krishnaswamy | September 2011 | Enterprise Articles Microsoft
A Query is a question you pose to the database so as to retrieve a specific piece of information in the database. The querying in LightSwitch can be best understood by looking at how it is structured. Querying in LightSwitch can be carried out using the built-in Query Designer but more advanced querying can be carried out using code.
This article by Jayaram Krishnaswamy, author of Microsoft Visual Studio LightSwitch Business Application Development, describes the use of the built-in Query Designer in the IDE to query the entities in the data sources.

BackTrack 5: Advanced WLAN Attacks
by
Vivek Ramachandran | September 2011 | Linux Servers Open Source
Wireless Networks have become ubiquitous in today's world. Millions of people use them worldwide every day at their homes, offices, and public hotspots to log on to the Internet and do both personal and professional work.
In this article by Vivek Ramachandran, author of BackTrack 5 Wireless Penetration Testing Beginner’s Guide, we will look at how we can conduct advanced attacks. We will primarily focus on Man-in-the-Middle (MITM) attack, which requires a certain amount of skill and practice to conduct successfully. Once we have done this, we will use this MITM attack as a base to conduct more sophisticated attacks such as Eavesdropping and Session Hijacking.
We will cover the following:
- Man-in-the-Middle attack
- Wireless Eavesdropping using MITM
- Session Hijacking using MITM
Routing in Kohana 3

Request Flow in Kohana 3
by
Jason D. Straughan | September 2011 | Open Source
Kohana utilizes the HMVC design pattern, and allows us to create requests essentially anywhere within our applications. The request flow is the order in which files are loaded, starting with index.php and moving throughout the framework, loading essential files, processing the requests, and rendering any output.
In this article by Jason D. Straughan, author of Kohana 3.0 Beginner’s Guide, we will learn:
- What HMVC is, and how it works
- Kohana’s Request Flow

FreeRADIUS: Working with Authentication Methods
by
Dirk van der Walt | September 2011 | Beginner's Guides Networking & Telephony Open Source
Authentication is a process where we establish if someone is who he or she claims to be. The most common way is by a unique username and password. This article by Dirk van der Walt, author of FreeRADIUS Beginner's Guide, teaches authentication methods and how they work. Extensible Authentication Protocol (EAP) is covered later in a dedicated article.
In this article we shall:
- Discuss PAP, CHAP, and MS-CHAP authentication protocols
- See when and how authentication is done in FreeRADIUS
- Explore ways to store passwords
- Look at other authentication methods
FreeRADIUS Authentication: Storing Passwords
by
Dirk van der Walt | September 2011 | Beginner's Guides Networking & Telephony Open Source
In the previous article we covered the Authentication Methods used while working with FreeRADIUS. This article by Dirk van der Walt, author of FreeRADIUS Beginner's Guide, teaches methods for storing passwords and how they work. Passwords do not need to be stored in clear text and it is better to store them in a hashed format. There are, however, limitations to the kind of authentication protocols that can be used when the passwords are stored as a hash which we will explore in this article.

Jate Wittayabundit | September 2011 | Web Graphics & Video
Only Unity fits the bill of being a game engine that allows you to create a full 3D game for free, and with phenomenal community support.
In this article by Jate Wittayabundit, author of Unity 3 Game Development Hotshot, we will learn how to create a rocket launcher. Here, we will first use the FPS camera and controller from the Unity built-in FPS package, but we will tweak our camera view to see from the character's shoulder as in Resident Evil 4 or 5. Then, we will adapt the built-in FPS controller script to be able to play the animation of the character, and make the controller similar to the Resident Evil style controller. Next, we will create a rocket prefab and the rocket launcher script to fire our rocket, which will also include the use of the built-in fire explosion particle and custom smoke particle effect from the launcher when we fire.
