Notice that an independent game development studio, Zero Point, is working with the community fairly closely to produce a space shooter called Interstellar Marines.  They are funded largely by pre-sales of the game, and to maintain credibility, they release video and game demo material so the community can see their progress.  Their “Bullseye” training area [...]

My Emacs startup time was stretching beyond 10 seconds, which seemed a bit offputting even for a text editor cum operating system. I do have a fair amount of elisp loading at startup, however, and though I have played with byte-code-cache, I determined there must be an easier way to compile all my elisp files [...]

It took me 30 years, but I woke up this Sunday morning and realized that rational numbers can be expressed as the ratio of two integers.

By far the most brain-bendingly elegant definition of all the Fibonacci numbers I have ever encountered: (def fibs (lazy-cat ‘(1 2) (map + fibs (drop 1 fibs)))) Found over an the clojure-euler wiki.

Just watched the December 2007 Google Authors session with Randall Munroe, creator of the XKCD webcomic.  Really good talk; he seems like a real geek, which is awesome.  He inspired me to sign up for Project Euler, which I have.  I did the first problem in a couple of minutes, and visited the forum to [...]

Discovered that WordPress has a great built-in feature that allows you to post entries by email. Setting it up was easy…and it may give me a way to post updates when I’m behind Nazi firewalls.

Trying to figure out if there is anything in the canonical definition of streams (lazy lists) that says that you need to keep the initial elements of the stream after use (if, for example, you’re recursing down the list and the head elements are getting garbage collected). Can streams be used as iterators when traversed [...]

Discovered Backpack a while back (February), a service from 37Signals that allows you to manage your data online in a variety of ways.  It seems like a shame to use their service when you have your own domain, so I decided that some of their features I could make use of with a “journal” approach [...]

Figured out how to generate a list of all k-element combinations from a set of n elements using double recursion. Apparently, the solution I developed is the “classical” way to do it, but it was challenging nevertheless.
