DDD—Data Display Debugger
ddd has more features than I have covered here; however, this article should give you a good start. It is refreshing to see Unix enter the modern era with graphical front ends which do not limit the user. When I first found ddd, I was quite impressed at its potential for novice Unix programmers. However, I also find myself firing it up quite often, even though I am a fully “qualified” Unix hacker with many gdb scars. The simplicity and elegance of ddd will make even the most die-hard shell fanatic roll over and accept it in many situations.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
