Linux Journal Issue #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.

News Flash: Linux Kernel 3.0 to include an on-the-go Expresso machine interface! Ok, maybe not, but Linux is definitely going mobile, from phones to e-readers. Find out more inside about Android, the Kindle 2, the Western Digital MyBook II, The Bug, and Indamixx (a portable recording studio). And if you've gone mobile and you been wanting more Emacs in your life then check out Conkeror.
To compliment the mobile we've got the stationary: parsing command line options with getopt, checking your Ruby code with metric_fu, and building a secure Squid proxy. How is this stationary you ask? What can we say? It's not. We just wanted to see if anybody actually read this part of the page :) .
All this and more, and all you have to do is get your hot sweaty hands on the latest copy of Linux Journal.

agape
On January 14th, 2008 Jesus Arocho (not verified) says:
The word is actually from greek. The interpretation that it refers to the highest kind of love, as opposed to philia or eros, is mostly Christian in origin. The word is not much found in extant ancient greek texts.
Eros is explicitly sexual whereas philia is love as in brotherly love. The highest kind of love, agape, would be of an unconditional and sacrificial nature, such as the Christ's sacrifice on the cross.
