    I just started a blog in which I will be posting “programming etudes” that provide practice “for the enjoyment and education of the savvy programmer.” It will be updated weekly. Today’s exercise is about generating text via a markov chain.

    The IOCCC encourages and rewards bad coding practices. Should not be on this list.

    The USACO training pages are pretty good but only C, C++, and Pascal are allowed.

    CoderCharts (http://codercharts.com) is the new kid on the block in online coding / programming contest. Right now we are holding our first contest in which there are 8 puzzles of various difficulty levels. Contestants can choose to use whatever language they feel like (we support quite a wide range of languages).
    The contest is going to end in 2 weeks. At the end of the contest, ther will be a lucky draw to give away an iPad.
    Hope all you coding enthusiasts give it a try.
