Get geeked

For those budding (and indeed established) geeks out there, a few resources from O’Reilly to get you off on the right foot:

1. Alphabetical Directory of Linux Commands. All the way from agetty to znew – a very handy command-line companion with all options explained and exampled (yes that is a verb). One for your bookmarks.
2. PHP Foundations. A programmers guide to learning PHP for people with no PHP experience. Heaps of articles starting from basic syntax up to PHP objects and C-style references. Good stuff.
3. Summary of Regular Expressions. We’ve all gotta learn regex at some point. Maybe.
