Sean B. Palmer

I am an early modern historian, with a background in the computer sciences. I'm working on several projects, including a fun book about metatropes.

One of my hobbies is to research random things. I discovered a previously unsuggested typology of the Cumbric language, and antedatings for the words meteorite and aerolite. I translated The Freswæl from Old English, and Ar Niwl Maith from mediæval Welsh.

On the web I am most well known for writing and maintaining an open source IRC bot called phenny. I was an editor of the W3C's EARL 1.0 and XML Accessibility Guidelines specifications, and I've contributed to books on HTML, Javascript, and the Semantic Web.

In 2008 I developed an independent proof of the Pythagorean theorem, but it took me two more years before I figured out why exactly six circles surround another circle. I would like everybody to know that CSS px is an angular measurement.

Once I rode a horse into my neighbour's garden, quite surprising my neighbour.
