Embedded Linux - Programming and debugging. Where to start?

I have been scouring the net trying to find a clear definitive guide to getting started with embedded Linux. I have only found vague answers to my questions. I really am hoping that someone can give me some clear answers and advice.

I am used to programming microprocessors with an IDE and JTAG debugger. I really like all the benefits of developing with an IDE. The biggest advantage for me is being able to single step and view variables at run time.
Can I do this with a Linux based board? Everything I have read so far refers to terminals, make files etc. Programming and debugging this way can be time consuming especially when you are new to whole environment. I have been through this before.

I have seen some references to Eclipse that have the ability to set break points and single step but it wasn't clear how this worked. Can you literally single step your code on the target device and if so how exactly does it work?

I would like to buy a development kit with an ARM but I want to be sure that the kit is well documented, has sample code, is preloaded with Linux and will allow me to develop and debug with an IDE. I looked at the TS series from Technologic Systems. Is this a good choice for getting started?

Well, maybe some people might find it otherwise. Almost all developers(even for commercial purposes) use cscope and vi for for linux based development(Atleast i have seen a lot of them). Yes IDE based source code navigation/debugging is easier, and maybe the __visual__ itself presents more life for some people, but that is an individual choice.

To get started with embedded programming, yes TS series of boards are very good, __but__ mind that most of them __does not__ have JTAG debugging capability. the JTAG pins are there, but they are used for programming the onboard CPLD and is not connect to any processor chipset / flash, which means you cannot debug or burn the flash using a JTAG debugger.

But said that __TS__ series of boards(i have a TS-7200) are good ones to start with., you can hunt around for other boards as well.

How to Build an Optimal Hadoop Cluster to Store and Maintain Unlimited Amounts of Data Using Microservers

Realizing the promise of Apache® Hadoop® requires the effective deployment of compute, memory, storage and networking to achieve optimal results. With its flexibility and multitude of options, it is easy to over or under provision the server infrastructure, resulting in poor performance and high TCO. Join us for an in depth, technical discussion with industry experts from leading Hadoop and server companies who will provide insights into the key considerations for designing and deploying an optimal Hadoop cluster.

Red Hat White Paper: Using an Open Source Framework to Catch the Bad Guy

Built-in forensics, incident response, and security with Red Hat Enterprise Linux 6

Every security policy provides guidance and requirements for ensuring adequate protection of information and data, as well as high-level technical and administrative security requirements for a system in a given environment. Traditionally, providing security for a system focuses on the confidentiality of the information on it. However, protecting the data integrity and system and data availability is just as important. For example, when processing United States intelligence information, there are three attributes that require protection: confidentiality, integrity, and availability.
