- mrjob lets you write MapReduce jobs in Python 2.5+ and run them on several platforms. I contributed a substantial part of the code through version 0.4 and still do code reviews and write documentation. mrjob is currently the most popular Python library for working with Hadoop as measured by Github stars.
- Literally Canvas is an extensible HTML5 drawing widget. I’m trying to bring in-browser doodling to the masses in terms of both developers and users. It’s the first thing I’ve started that’s become reasonably popular.
- Tron is a centralized system for managing periodic batch processes and services across a cluster. I maintained Tron for a while at Yelp and wrote much of the documentation.
- enzyme2sqlite is a tiny tool to convert a bioinformatics-related flat file format to a badly schemad SQLite database. I mention it because I may have accrued up to two users.
- I’ve contributed code to the Elastic MapReduce part of boto, the Python library for working with Amazon Web Services.
- I once sent a patch to the Mac version of LÖVE because I like to see good libraries succeed.
