The Inverse Graphing Calculator
The Inverse Graphing Calculator was written over a weekend when I
was first dabbling in basic LAMP-style web development. It promptly
went viral, and has continued going viral every now and then ever since.
Enter an English phrase, and the IGC will generate a mathematical
equation whose graph spells out that phrase on the xy-plane.
Productivity software webapp focused on recurring tasks with no
fixed deadline. You enter tasks, enter a rough estimate of how
often you'd like to do that task on average. Any time you log in
and look at your tasks, you'll see them sorted based on urgency.
Patterns of Resemblance Calculator
A sophisticated engine for performing calculations on geometric
data structures called patterns of resemblance. Patterns of resemblance
notate ordinals up to the ordinal of PI11-CA0.
Some of the algorithms implemented in this engine are original and were
printed in the Archive for Mathematical Logic.
