Wicked Cool Java: Code Bits, Open-Source Libraries, and Project Ideas
$29.95
Wicked Cool Java reads like a blog. I'd probably visit the blog regularly. Some days I'd skim, some days I'd read through thoroughly, and occasionally I'd bookmark for future reference. I'd probably go to the blog and do searches now and then when attempting to approach new (to me) problems, and I'd browse the archives some days while procrastinating.

Topics covered range from generics and String manipulation to MIDI and harmonics, from graphs and graphics to scientific applications, from semantics to logic, artificial intelligence and neural networks to programming lego robots.

I'm sure every single bit covered is Wicked Cool to someone... though it is difficult to imagine any one person finding ALL of it to be Wicked Cool. Except maybe the author, who expresses an admirable amount of enthusiasm and interest!

The target audience is people who have a good basic familiarity with Java, and are ready to see what wonders will pop out if you poke it in unexpected places.

If you are very new to programming, a lot of the discussions might be difficult to follow.

Open-Source Robotics and Process Control Cookbook: Designing and Building Robust, Dependable Real-time Systems
$62.95
Edwards does the reader a great service by going into why decisions are made. For example, Edwards leads you through the choice of which PC motherboard he was going to use for the project. His decisions and considerations were very insightful to me. Although the board(s) selected are now out of date according to the manufacturers, using his process will enable you to find motherboards to be able to handle the tasks in the book. Next, Edwards leads you through setting up Linux using BusyBox and how to divide the system up using a compact harddrive and a CompactFlash. All in all, while I consider myself an expert linux user, I found his coverage of material very interesting. Another keeper for my robotics bookshelf.

Open-Source ESBs in Action: Example Implementations in Mule and ServiceMix
$44.99
A good book. + I got the pdf version free.. So in case you are planning to buy only PDF version, you can put few bucks extra and get hard copy and soft copy too. I particularly wanted this for Mule.
*** However for mule I feel the mule source documentation and user guide (on mulesource.org) is also quite well (if u have read EAI book by Harpe and Woolf).. especially if you try out the examples on your own.
