PyWE

PyWE (Python Windows Environment) is a collection of scripts that make it easier to install multiple versions of python, switch between different versions of python and create/activate/deactivate per-python virtual environments.

CardWiki

CardWiki is a wiki that is patterned after TiddlyWiki. Unlike TiddlyWiki, CardWiki is designed with hosting in mind. CardWiki uses a notecard metaphor, rather than a page metaphor, so you can look at and edit multiple cards at the same time. If you're the sort of person that likes to keep 100's of tabs open, or you love to accumulate tons of notes on scraps of paper, CardWiki might help you view and organize your thoughts.

Currently, CardWiki is an open source Python project that you can set up and run yourself. Contact me if you want to see a hosted version of CardWiki

Straight-Laced

A theme for Pelican blogs. It's the theme this website is using. Straight-laced is plain jane, but responsive and marked up with both semantic markup and schema.org markup.

Pretty Good Computer

Pretty Good Computer is a toy computer I built to simulate the z-machine as described by jgc. I enjoyed working out the problems long hand, but thought that I could have a computer do the repetetive scut work; they're better at it after all.

The z machine has unlimited memory locations that are numbered, so we can refer to them. The cpu understands 3 instructions:

  • z_n_
    • z zeros, or initializes, the value at memory location n
  • i_n_
    • i increments the value at memory location n
  • j_n_!m)l
    • j compares memory locations n and m's value. If they are equal, the program proceeds to the next line, otherwise it goes to line l

Of course, I can't figure out a good way to represent infinite memory locations in a browser window, so we are stuck with 16-bits by default. This is user-editable, if you need more space to really explore whatever you are doing.
