I know... I know. It's been a while
Quotes of the Week
- arianvp__: after 5 hours of hacking my code works || now its 3 am || Types make a lot more sense when I'm tired for some reason
- dmwit: "Any coder worth his salt can do the impossible."
- hodapp: Math is too hard. Let's use JavaScript.
- Zemyla: I imagine if [Edward Kmett] had found C++, he would be writing template definitions that would make the faces of the Boost team melt off.
