Linux Journal Contents #158, June 2007
This month's issue concentrates on languages, even to the point of metaprogramming concepts where you write programs that write programs! PHP programmers will appreciate some help on how best to validate email addresses. Sun's Simon Phipps explains the move to GPL Java, and defends Sun's motives for protecting Java from corruption as long as was necessary. We'll teach you how to access databases asynchronously from Qt 4.x, which is a big improvement over default Qt 4.x database handling.
As always, there's much more. We'll take a look at the compact but powerful lua, a language so flexible even Blizzard uses it to allow players to extend World of Warcraft. And Christof Wittig is back with Ted Neward to explain the impedence mismatch between object-oriented languages and relational databases.

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 The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model.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
