I am David Richfield, a German chemical engineer / biochemist born in South Africa. I'm also a founder member and former director of [http://www.wikimedia.org.za Wikimedia South Africa], the South African Wikimedia Chapter. I also created the [https://parliamentdiagram.toolforge.org/parlitest.php parliament diagram tool], which is widely used to create diagrams for political articles on Wikipedia.

My username comes from IRC: "/me" is a shortcut which inserts your username.

I enjoy learning languages, graphic design, 3D modeling with Blender, cartography on OpenStreetMap, computer programming, playing Go and promoting free software. In 2016, I started juggling.

Here's a Limerick: \int_1^\sqrt[3]{3} \! t^2\,dt \cos(\frac{3\pi}{9}) = \ln(\sqrt[3]{e})

You can make diagrams using [https://parliamentdiagram.toolforge.org/parlitest.php this online tool]!

I started work a while back on a tool to render svg diagrams for legislatures - I started out with a tool that spits out a rectangular diagram with a title and a legend. In May 2010, I saw some very nice arch-shaped diagrams drawn with User:Habbit's ADSvote program requested for conversion to SVG on WP:GL/I. Instead of doing manual SVG conversion, I programmed a similar algorithm, which I now host on Wikimedia's Toolserver (link above). The source code is [https://github.com/slashme/parliamentdiagram hosted at GitHub] - Bug reports, feature requests and patches are welcome!

The arch tool is quite popular for election results on Wikipedia, but the Westminster-style tool is still under development: a standard style has not yet been clarified, so if you use it, expect criticism and/or correction. If the output is not as you expect, consider editing with Inkscape and saving the result as a "plain SVG".

You can also upload the diagrams directly from the tool. You can see the most recent uploads [https://commons.wikimedia.org/w/index.php?tagfilter=OAuth+CID%3A+538&limit=1000&days=30&title=Special:RecentChanges&urlversion=2 here].

There have been significant contributions to the tool by Ambady Anand S, Ranjith Siji, and [https://github.com/Rade-Mathis Rade-Mathis].

=Camera=

I bought a Canon PowerShot A630 in April 2007, and have since started contributing photos to Wikipedia. In 2008, due to an insurance payout after a stupid accident involving seawater, it was upgraded to an A650IS, quite a nice camera, and it runs [http://chdk.wikia.com chdk] quite nicely, thanks! That camera was eventually stolen in 2013, and I have replaced it with an SX270HS, which has the new Digic 6 processor. There is [http://chdk.setepontos.com/index.php?topic=11550 a development CHDK version] for this model, but I have not tested it yet: it is still alpha software as of November 2014. I've also since bought a Canon EOS 600D. It's a very nice camera! I have had good success with macro photography using extension tubes with the stock lens, but I later also bought a combination macro/telephoto lens.
