Got pwned at the last TopCoder single round match. The easy problem could be solved by using a O(n) string search method. I tried Rabin-Karp, but made a very stupid mistake. A learning experience nonetheless. Posted a longer rant/post-match analysis in my LiveJournal blog.
Downloaded source of quite a few open source projects in the last few days. Going through them very carefully. mod_virgule code still baffles me. But I'm slowly making progress. The fact that many of the projects in the projects page here are either dead or have broken links (some even sound bogus) is also causing me some frustration.
Solved another problem at SPOJ. Currently mine is the only accepted Python solution there, but probably not for long.
