Attention PL/SQL developers - Steven Feuerstein's PL/SQL Challenge website has just been 2.0'd
If you haven't given it a go, now is the time for a fresh crack. It's not just a daily quiz, but a place to learn and keep up to date with Oracle technology - not necessarily with new features, but techniques and capabilities you may not have been aware or, nor had the exposure to.
That and everyone has a chance to win something.
Kudos to Steven and his team of merry men.
