I made a project on Wikipedia (a free online encyclopedia) to fix the unreasonably popular mistake of leaving off punctuation at the end of paragraphs. It's called Project Punctuation, and it's a good way to spend time doing something easy and useful in order to, say, avoid working on your thesis proposal. It's based on my wikipedia-analyzing "periodbot" (source), which is written using a basic interface to mysql for mlton (source).
This is an awesome paper (as seen on slashdot). The basic idea is that since light transport is reversible, you can perform the following experiment:
* Set up a scene * Aim a projector at it ("light source") from a fixed location A * Take a number of pictures of the scene from a fixed location B, under different lighting conditions generated by the projector * perform a calculation on this set of images that allows you to view the scene from the location of the light source.
The best part is the final page of the paper, where they reconstruct a fairly high resolution image of the obverse of a playing card from 5,000 pictures of its reverse (and a nearby book) under different lighting conditions. World series of poker, here we come!
I uploaded the new version of my software, midimml. Midimml is for composing Nintendo tunes using a MIDI editor. This version, aside from fixing some bugs, adds the ability to define instruments for your Nintendo bleeps, which allows you to make more interesting sounds than just straight-up square waves. I wrote two new songs using it for the Famicompo mini vol. 2, but their identities are secret until after voting ends (not that I have any particular aspirations for winning!).
