I write lots of open-source software in my spare time.
Or maybe it would be more accurate to say
that I write software to solve my own problems
and support my own projects outside of the realm of software,
and then I share most of it with others.
I aim to create software that does exactly one thing well
and is simple and small,
easily understood and maintained by one person
and using as few dependencies as possible.
My typical development toolkit includes
Python, SQLite, Flask, Qt, curses, and the Linux/Unix shell.
While I tend to reach for Python when I see a new problem,
because I have many years of experience with it
and it’s so incredibly easy to start a rapid prototype in,
I have also worked in
and I enjoy playing with different languages and paradigms.
See the work page for what I get paid to do during the day.
You can find all these tools on my GitHub page.
I keep these roughly in order of polish from most to least,
so if you want to judge what I’m capable of, start at the top!
is a stand-alone, tag-based bookmark manager
with a link checker, WayBackMachine integration, and more.
is a tool for the TiddlyWiki wiki/notebook software
that integrates with the flashcards program Anki
so you can interleave flashcards with your notes.
I maintain a popular add-on, the
Anki Lyrics/Poetry Cloze Generator,
to make it easier to study poetry with Anki.
This is a system
for dream journaling on the computer
that follows the Unix philosophy.
It’s one of my favorite pieces of software
(other top contenders: Git, vim, PowerShell, ledger).
I’m interested in Reverse Polish Notation
and, finding the only popular computer-based calculator that uses it a bit limited,
decided to implement a Python calculator that uses it.
The result, esc,
is highly extensible and user-friendly,
and it’s the calculator I reach for on a daily basis.
An abbreviation engine
for obfuscating and shrinking text in a human-readable manner.
Written in Lua, which has proven a fantastic fit for this app
– fast, simple, and beautiful.
A work journal and time tracker written in PowerShell,
reading from a plain-text file
and taking advantage of PowerShell’s powerful built-in data-manipulation features
to answer all kinds of questions about the data.
A Qt application
for keeping a personal index with potentially thousands of entries
pointing to books you’ve read, diary entries, notes, and anything else you like.
I wrote it as part of my personal documentation and history project,
The Records Project.
- Monthly Calendar Printer:
A quick Python script
that prints yearly calendars for your wall.
Particularly handy for keeping track of habits and similar daily notes.
Another Python script
that typesets book or notebook indexes.
Tabularium can export entries in Mindex format
so you can paste them into the back of a book.
I wrote an SMS bot for my touring choir.
It allows users to “text themselves in” to the bus
so organizers know who hasn’t made it back yet
and don’t leave anyone behind.
- Clicker Quiz Manager:
I wrote a custom software application
to generate daily quizzes for use on clickers in a classroom setting.
The software allows a teacher to randomly select questions from a large pool
based on the time since the class last saw information about a certain topic
and students’ past performance.
This gives students more review on the topics
that they are likely to need on any given day.
These aren’t my projects, but I’ve helped out with them.
- Anki: I have been using the spaced-repetition flashcards program Anki since 2009.
For five years, I had a part-time job helping out on the support forums,
and during that time and occasionally afterwards I have contributed to Anki’s codebase.
I have developed and maintain an assortment of Anki add-ons,
including TiddlyRemember and LPCG, listed above.
In the pipeline
These projects aren’t publicly available yet,
but likely will be once I get them past the alpha stage.
A simple recipe management tool for my family to share recipes.
Distinguishing features include use of an external text editor
with a markup language for formatting
and the ability to print cards, cookbooks, and HTML pages directly from the app.
A tool to help maintain neat organization of your files
by checking rules throughout the filesystem.
Basic issues include use of nasty characters in filenames,
uppercase file extensions,
and so on.
However, you can quickly write your own rules in Python
to check any kind of convention you like.
