Status (August 2016)
Pre-schooler schools me in checkers. Toddler laughs.
I work at Mozilla in the
somethingsomething group on:
This is the list of projects I'm working on:
- Crash-stats (Socorro) -
Crash-stats (AKA Socorro) is the crash collection, processing
and analysis system we have at Mozilla for Mozilla products. It's used
elsewhere as well. I succeeded Lars and several other people and now
maintain and develop the backend.
- Bleach -
Bleach is a allowed-list-based HTML sanitizing library that escapes
or strips markup and attributes for display in HTML.
James Socol started Bleach years ago and over time stopped using it.
In December 2015, I took over maintenance of the project.
- Everett -
Python configuration library that makes automated configuration
documentation and testing easy.
- Markus -
Python library for generating metrics for arbitrary backends (Datadog
statsd, statsd, logging, etc).
- Dennis -
Dennis aids your l10n development woes! It lints .po files for things
that will crash your production server! I translates your strings in
various ways to help you suss out l10n problems!
Writings / Editings / Technical Reviewings
This is a list of things I've written, edited or did technical review
on. I've done a lot of documentation work for projects I've worked on and
that's addressed poorly here. This is a list of books, articles,
manuals and the like.
- Documentation patches for projects of code I use.
- 2017 - Python Microservices Development -
Tarek Ziade wrote the book and I did the technical review. It's a great
survey for writing systems using microservice architecture using Python.
- 2010 - Quick Python (second edition) -
Naomi Ceder updated and heavily re-wrote the second edition of this book
in 2009. I did the technical review. It's a solid book for Python 3.
- 2004 - Bee Careful, Marvin
- This is a children's book that my fiance (now wife) and I wrote in
2004/2005. I'm also in the process of posting the source code online in
a bzr repository and a Trac instance and relicensing it under the Creative
Commons BY-NC-SA 3.0 license or alternatively the GPL version 2 or later.
We encourage you to download it and print it out and/or purchase a
professionally bound copy from Lulu. We're in the process of writing
- 2012 - Open Advice - I helped edit
the book early on, but wish I had done more. The book is a fantastic
collection of essays from a variety of people on what they would have
liked to have known when they started contributing to free software.
It's a phenomenal read---I highly recommend it.
- 2010 - GNOME Journal - I've contributed
to GNOME Journal as an editor and as a writer.
- 2007 - Mapping Demeter
to XML Schema and XPath 2.0 (May 2007) - This is a paper I wrote during a
research and readings semester with Karl
Lieberherr. It maps syntax and semantics between Demeter class dictionaries
and traversals and XML Schema and XPath 2.0. It's a one-way mapping, however.
This is useful for someone who was going to implement some of the graph-traversal
algorithms used in Demeter in a XPath 2.0 component that's XML Schema aware.
- 2007 - Summary of
research on modularizing Demeter class dictionaries (May 2007) - This is
another paper I wrote during a research and readings semester with
Karl Lieberherr. It's a
summary of the readings and research I did for the semester. I didn't get as
far as I wanted to on that project, but I did learn a lot more about modularizing
- 2006 - CSG260
materials - This is a bunch of stuff I'm mirroring here that I wrote
when taking CSG 260: Advanced Software Engineering in Fall of 2006 at
Northeastern with Karl
Lieberherr. It's probably not very exciting unless you're taking one
of his classes or following the constraint satisfaction problem solving
- 2006 - Cleaning
Up Pyblosxom Using Cheesecake -
A case study for using Cheesecake to overhaul
a pre-existing Python-based project. Pyblosxom 1.4.x included a lot of fixes from
the cleaning up. Pyblosxom 1.5 included more. (The original article was posted on
the pycheesecake site, but that has since gone away, so this link points to
the version I have in my blog.)
- 2005 - The Pyblosxom Manual - Years ago, I wrote the original manual using
DocBook, but John, Ryan and I rewrote it in reStructured Text for Pyblosxom
1.4. Then we redid it using Sphinx.
- 2005 - LPC Manual - A manual
on LPC that covers the language and coding in the language to build
areas. It's sort of targeted towards people with little programming
language or coding experience. It was something I worked on from
time to time as I discovered people had conceptual difficulties
with various aspects of LPC the language. It was never completed. Also,
it looks like they took it down. Boo.
- 2003 - regexp haiku -
A regexp haiku I wrote that the editors liked and had posted on java.net.
Oracle bought Sun and then subsequently destroyed all beautiful things, so
it (and the java.net site) don't exist anymore.
- ANSI codes - A
listing of ANSI codes that I found, overhauled, and added to while working
on Lyntin. For some reason, it's a very popular page on my site.
- Lots of documentation and project specifications for the companies
I've worked at. Since this is a catch-all for what are essentially
internal documents, I can't share them with anyone.
I've worked on a lot of projects over the years. Some of these have
been passed on to other people while others have been abandoned
- Edwin -
Edwin was another sprint system that used Bugzilla data for sprint planning.
It had some interesting features and it was a good reason to experiment
with React. We decided to stop working on it after we hit some
architectural issues that were impossible to fix.
- Ernest -
Ernest was a sprint system that used Bugzilla data for sprint planning.
It was nice and met our needs and a good reason to experiment with Angular,
but then we decided we needed something better and implemented Edwin.
- elasticutils -
I took over the ElasticUtils project, overhauled it, radically improved
documentation and tests and project infrastructure, then continued
to maintain it. At PyCon, I talked with Honza about it and Elastic.co's
plans. We worked out some API issues with elasticsearch-dsl and collectively
decided to abandon ElasticUtils for elasticsearch-dsl.
- django-eadred -
Sample data generator for Django projects. This satisfied a need we
had on a bunch of projects, but there isn't enough interest to continue
- Douglas -
Douglas is the spiritual successor to Pyblosxom. I cleaned up a lot of icky
things in Pyblosxom, switched it to use Jinja2 for template rendering,
cleaned up the plugin system, added a ton of tests and implemented
preview. I used this for a couple of years and then decided I didn't
want to maintain my own blogging platform anymore and switched
- Input (fjord) -
I helped rewrite Input and then maintained and developed it for several
years supporting Mozilla's User Advocacy team. Input was the feedback
system for Mozilla products.
- SUMO (kitsune) -
I worked on SUMO for several years maintaining and developing the
software that we used to support Mozilla products.
Python Miro Community,
lots of software for this -
In February 2010 I started Python Miro Community--a site that indexes
videos about Python (conference talks, tutorials, etc) from around the
Internet. In 2011, I was awarded a PSF Grant to enhance the site
with Universal Subtitles support, pay for 12 months of the Miro Community
service, and continue maintainence of the site. I continued curating videos
and working on Python Miro Community until around March 2012 when I decided
the Miro Community platform wasn't doing what I needed it to. So I wrote
a whole new platform and replaced Python Miro Community with
On pyvideo.org, I wrote the software and managed the infrastructure. I
worked with Sheila Miguez curating videos, writing documentation, coordinating
with conference video organizers, managing community and various other things.
In July 2016, I stepped down and passed off pyvideo to Paul Logston of
- GNU MediaGoblin - I
wrote the initial documentation, built the infrastructure, wrote the initial
plugin system and helped bootstrap the project.
Miro is a desktop media player that runs on Windows, OSX and GNU/Linux. This
is the project I worked on fulltime for PCF and I continue to contribute. I
still contribute to the project, but in a decreased capacity.
- Pyblosxom -
Pyblosxom is a file-centric weblog engine in the spirit of Blosxom but
written in Python.
I worked on Pyblosxom for nine and a half years (January 2003 to June 2012).
I was the maintainer for Pyblosxom for many of those.
I was the primary author of the Pyblosxom manual which was originally
written in docbook but has since been converted to restructured text.
I released Pyblosxom 1.4 incorporating work I did while helping out on
Cheesecake and also
pulling in Paste support.
I mentored a GSoC 2007 project building a web interface for Pyblosxom called
I released Pyblosxom 1.5 which was a significant overhaul of the project and
plugins - These are plugins for Pyblosxom I wrote or took over
from other people.
- Lyntin - Lyntin
is a mud client written in Python which shares many commands with Tintin.
It has since diverged from Tintin style in many ways. It was listed as one
of the largest
Python projects on the Python wiki for a long time. There are a number
of larger projects now. I stopped actively developing Lyntin in
May 2004 when I passed the project off to Eugene. Seems like the project
died pretty soon thereafter.
- Lyntin plugins
- These are plugins I wrote for Lyntin. I don't maintain them
any more and I think the AIM one no longer works (I think AOL disabled
the TOC protocol that it requires), but they're still useful to some
- Dark Rifts - I've spent a lot of
time writing various
mud engines and most of those
projects petered out. I had a friend who introduced me to Dark Rifts, I
became a coder there and then an admin. Over the course of three years, I
wrote a lot of functionality (vector-space search system for in-game
documentation, time/weather daemon, functional programming functions,
bridge code between MudOS and the web-site, bridge code allowing for
mud-account authentication for pure-ftpd, gobs and gobs of documentation
including the beginnings of an LPC manual, ...), fixed a lot of bugs,
and wrote a bunch of areas as well. Then after a craptastic
conversation in January 2007 with one of the other admin, I retired
permanently, which was unfortunate and bummed me out. If I do mud
development again, I'll look at helping out on
or something similar.
- Stringbean -
Stringbean was a Python-based mud that I was working on after several
other projects had been abandoned. There were some interesting things
I wanted to try and then I discovered that Twisted had already done some
- Bluemud - Bluemud was
a project I worked on with a few other people back when I was in California
in 2000. It was a Java-based mud which used Jython as the in-game world
language. We bumped into a series of problems with Java security and
Jython. We were looking into rebuilding what we had done in C with an
embedded CPython VM, but due to various life issues (I moved from west
coast to east coast among other things) the project kind of fizzled out.
One of the coolest things we did in Varium and then pulled into Bluemud
was in-game screen editors. I wrote a mini version of Pico and we had
a mini version of Emacs (called Nomacs), too. Pictures are
here. We had
the NAWS telnet option working (so you could resize your telnet window and
the editor would resize with it) and towards the end I was working on very
rudimentary syntax highlighting functionality. To build these editors, we
implemented a primitive curses-like windowing toolkit.
One part of Bluemud was a mini-project I called
which took an asciimap and converted it into a tiled image. The purpose of
this was to generate a web-based atlas of the world and its areas from a
series of ascii-maps. I still use it occasionally for gaming.
- Varium - Alas, but the Varium web-site is no more. Varium was the
first Python-based mud project I worked on in 1998 and 1999. We got a
lot of interesting things working, but I think the scope of the project
was too huge (engine, mudlib, world, ...) for the small group of us (three
at the time) to complete. After Varium wound down, I worked on Bluemud
and pulled a bunch of the things we did in Varium into Bluemud.
- Bluemail - I wrote Bluemail as a Python CGI application back in
2000 or 2001 or thereabouts. The mission was to build a webmail client
that used the same folder structure and settings as Pine so that people who
used Pine when they were ssh'd into the box could use the webmail client
when ssh wasn't available. During one of the server switches, Bluemail
stopped working. Since then there have been a lot of advances in
Python-based web-application frameworks and Bluemail should be re-written
using one of those.
This site was written using Emacs and Vim (yes, both).
I use Nikola to power my blog,
InkScape for graphics and
Git for version control.
