Microsoft have this ‘spot the bug’ blog entry. And while the code size is trivial, people have been finding more than one bug! Of course if you want some more fun spot-the-bug items you could try the Secure programming @blogspot, or even the linux kernel. Ok, anyone who thinks I’m being smart by this one can just bite me. You could also try the Open Solaris code also. So there’s plenty of things to keep you occupied with in your bug finding tasks.
Of course, you could try to find the bugs in your own code 🙂
If it wasn't for carbon-14, I wouldn't date at all
