Current projects

• local-time - A Common Lisp library for manipulating dates and times.
• TempusMUD - a text-based multiplayer game of high fantasy and futuristic technology.

Snippets

• count-c-symbols (gpg) - a lisp program to tabulate symbol frequency in a C program. This is useful for removing unused functions or macros, or evaluating the connectivity of a symbol.
• a-star - a generic implementation of the a-star pathfinding algorithm written in lisp
• I wrote an elegant solution to return a list of unique random numbers, and implemented it in Common Lisp, perl, and C

Retired projects

• BTL - The Beautiful Templating Language, a Common Lisp interpretation of BRL
• hatchet - a HTML preprocessor that I use to maintain this site
• rbcast - A small, configurable streaming MP3 server
• random_domain - constructs and verifies unused domain names, written in lisp: I got bitmuse.com through this program
• Invaders - a 3d-rendered version of the classic invaders game using Vivis.
• Holler - a distributed netcast system for internet radio stations.
• simplelist - A perl script to implement a simple mailing list with no offline controls. Just define the roles of various email addresses in a config file and point an email address at it.
• Vivis - a 3d engine using Ruby as its scripting language.
• Realm-z - a ruby-based web forum used for TempusMUD
• gimel - a C++ mud framework, since abandoned
• rankmirrors - Parses a file for URLS and simultaneously pings all of them to find the fastest one. Great for finding the best mirror.
• quitmeter - A perl script to help you quit smoking. Just edit the file with the date you quit, the amount you were smoking, and the price of cigarettes. Remember: you only get one body.
• afk.c, a small program for UNIX that beeps and displays a message when someone logs in, displays a message when someone logs out, and checks for incoming email. Cleverly named to show "afk" when someone checks the who list. Requires libtermcap.

Humor

Just a few things I picked up around the web, dusted off, gave a little shine and placed here.

• A light-hearted look at the internet
• In the beginning...
• The evolution of a programmer

Common Lisp Resources

• CLiki - the Common Lisp wiki. An incredible community repository of information.
• CMUCL - my lisp compiler of choice
• Structure and Interpretation of Computer Programs - A heady introduction into computer programming. Uses Scheme as its programming language of choice. This is an online version of a print book.
• Common Lisp: The Language - in its 2nd edition, a definitive reference for lisp. This is also an online version of a print book.
• Common Lisp Hyperspec - The online reference to Common Lisp
• Successful Lisp - An excellent beginner's guide
• Lisp Programming Style
• Lisp Style Tips for the Beginner

Ruby

Ruby is an object-oriented scripting language. An elegant language, it fills the niche of programs which aren't throwaway but require little maintenance. For me, it effectively replaced perl as a web programming language.

• Official Ruby Language Website
• Ruby Central - Home of Programming Ruby, another online version of a reference book
