My hobby of programming has lead me to many random projects that struck my fancy over the years. Lots of projects were written for courses and I likely won't be posting those, since assignments are reused year-to-year, but a brief excerpt of the rest are categorized below.

Artificial Intelligence

There was a time when I wouldn't have considered this stuff AI at all, but I learned about it in AI class so I guess it is artificial intelligence.

Sudoku Solver: A solver for Sudoku puzzles written in OCaml. It is small and fast and avoids guessing as much as possible, though it has to guess in some puzzles. It will find multiple solutions if they exist, though technically they aren't suppose to.

Internet Stuff

Web stuff is mostly small, and unfortunately mostly untyped. Javascript for client-side stuff and PHP for server-side stuff is mostly what I do.

XML Templating Engine: A template-based XML/PHP engine for websites. Similar to a Wiki but it doesn't allow online editing of pages (...maybe in the future). It is based on very easy to write "TemplateProcessors" which allow inclusion of dynamic content. This project was joint with Jennifer Gillenwater.
FunkyMon: Haskell implementation of a general functional monitoring framework. Joint with Kelly Heffner. Some of the code is a little crufty, but generally reasonable. Amazingly it compiles without warnings, thanks mostly to Kelly. The makefile is a little bit hacked, Kelly(Darwin shell) was running with GHC 6.10.2, and I was running with GHC 6.8.2. (This was my class project for Harvard cs 222)
Sliding Tile Puzzle: In the days before I had access to server-side anything, I wanted to make a sliding-tile puzzle; so it is JavaScript only. This could evolve into a regular jigsaw puzzle, but that's probably a separate project. I can't/don't test in IE, but it should work in all of the standards compliant browsers (css hacks are probably enough to get it working in IE).

Random Stuff

Random/one-off code, mostly scripts which don't fit into other categories.

Morse Code Encoder/Decoder: If you don't send spaces between characters or words, it can be difficult to figure out what Morse Code says unless you're a expert. This little script might help. Note: it is terminal driven and has not been tested in Windows.
