anders pearson : code/research

i'm a programmer. i like computers because they do what i tell them to. i hate computers because they do what i tell them to. here's some stuff i've done:

cgi_app: framework for writing MVC web applications in python. port of the CGI::Application perl module.
Apache::Tidy: mod_perl filter for cleaning up dynamically generated markup and converting it to nice, clean XHTML on the fly.
thraxil weblog engine: written in perl using a postgreSQL backend. features templating for completely seperating the backend from the display, multiple user accounts, intelligent thread "bubbling", bookmarks and image support, and a nifty markov chain text generation feature. see thraxil to see it in action.
XinT: an innovative digital theremin. made with a Z-80 for my Microprocessor lab class.
hierarchical clustering of yeast genes by regulatory regions: some seriously optimized perl code for clustering genes by promoter regions. group research project for a computational genomics class at columbia. read the abstract for a better explanation.
eBLAST: Building a Better BLAST: More genomics research. Improving the BLAST sequence alignment tool.
location description program: a homework assignment for my Visual Interfaces class. it basically is a hack of the unix xv image viewer program that takes a couple files in a special format that are a map of some area and, when the user clicks on a location on the map, it prints out an english language description of the location. nothing fancy but kind of neat.
Homology Detector Program: uses protein motifs to search for homologous proteins within DNA and amino acid strings. see the project writeup. made possible with the excellent bio knowledge of omar. [source code]
RNA lowest energy conformation visualization tool: finds least energy structure of an RNA strand and displays it with a nice ASCII diagram of the connections. makes use of some slick but counter-intuitive dynamic programming tricks to do it in a feasable amount of time. [source]
bitmapping fonts with html tables: an obscene abuse of html. uses lots and lots of html tables to display bitmapped text using Derek's bitbet font. [source]

except where otherwise noted, all my programs are released under the GNU GPL (the exception is one that is released in the public domain). more coming...
