Parsing and evaluation of simple maths expressions for Exalted This intended to aid in evaluating simple calculations which appear on character sheets, especially for Exalted.

This is a TeX-to-HTML+MathML+CSS converter class using the Javascript-based KaTeX, interpreted by one of the Javascript engines supported by ExecJS. The intended purpose is to eliminate the need for math-rendering Javascript in the client's HTML browser. Therefore the name: SsKaTeX means Server-side KaTeX. Javascript execution context initialization can be done once and then reused for formula renderings with the same general configuration. As a result, the performance is reasonable. The configuration supports arbitrary locations of the external file katex.min.js as well as custom Javascript for pre- and postprocessing. For that reason, the configuration must not be left to untrusted users.

Kame (Japanese for turtle) is an implementation of the Logo programming language built as a challenge to myself. I wanted a simple way to introduce programming in Ruby to my daughter and thought this would be fun. With Kame, you control the movement of a turtle around the screen by programming commands. With these simple commands your turtle will draw you a picture. It's a nice introduction to programming for kids and will also help their maths :o)

Music Coder is a music programming library. It generates music entirely through code in the chosen programming language (Ruby). There are three main reasons a technically minded person would use Music Coder: Producing music: Write scripts that mimic human creativity, and put some randomness in it, giving you a program that can generate aesthetically pleasing music that is completely unique in each file generated. Scientific exploration: Use the functions in Music Coder to concisely apply algorithms or math to the structure and properties of sound. Making samples: create samples or sections of music that are too complex to be done by hand in graphical audio programs such as Ableton.
