Does trying to achieve goals actually matter? Yes. Yes it does. Consider if trying to achieve the goal of building cars has ever succeeded in building cars, which never appeared in nature.

Table of Contents (internal links):

Hashing
Here's a hash table, code for perfect hashing, a good hash function for hash table lookup, a FAQ, some theory, and code to search for new hash functions. I tried designing block ciphers and finding characteristics. I had an article published in Dr. Dobb's in September 1997.
Randomness
Have the cryptographic pseudorandom number generator ISAAC, a small noncryptographic pseudorandom number generator, a prize for breaking ISAAC, and ISAAC's background and theory. Also take some tests for randomness, and a table of orders of magnitude.
Boy Scout Skits
Aaarghhh!, Did You See That, Water, Water!, The Firing Squad, The World's Greatest Spitter, The Vending Machine, Dudley Dooright, The King's Raisins, Rent, The Old Gum, et cetera, et cetera, et cetera ...
Math
Look into pentagonal tiles, formulae for n-body orbit simulations, code for the HOMFLY knot polynomial, voting methods, choosing random passwords, jenny for pairwise testing, some error correction codes, and an april fool's design spec.
Testing
I have tools for pairwise testing (jenny), exhaustive testing (dice), testing hash functions, and a pattern for concurrency testing.
Physics
Consider perpetual motion machines, a dirigiped design, a scale model of the solar system, a page on exploring orbits with Javascript, Klemperer Rosettes, a simulation of Cruithne (a near-earth object), of figure-eight orbits, of binary star planetary orbits, a set of noncolliding orbits, some Dyson Swarms (pretty pictures!), some methods for the n-body problem, and a description of the javascript orbit simulator used.
Future Speculation
big data centers, a pedal-powered whale, AI, a protein computer, and Manhattan in space
Politics
Latest to oldest takes on political issues
Short Stories
Dragons Aren't Real, Cassie & Frieda, Voyage, Pancakes, Lima Beans, Harmonica, Police, Hawaiian Shirt, Demo, Dinner Plan, Godzilla, Imposter, Conspiracy, Costa Cola, Pointless, Marbles, Ignored, Minion.
Genealogy
Mina Lowry, Thomas Webb, Grandma's Interview, lots of others, and also genealogical fan charts and how many genetic ancestors you have.
Home projects
See my half bath, a house design that will never be built, a dollhouse that did get built, some recipies, some paper airplanes, and a roof rack for Justine's car.
Mom's Art,
Other
Here is my autobiography, a resume, a bit on software patents, SQL tricks from Oracle, the Book of Isaac, some birds, some music, some cartoons that I wrote in college, and some early Bob photos.
