Thank you, wikipedia.

ADDENDUM:

So that I also have something to contribute, here is rule 30 used as a random number generator, written by yours truly. (Though the idea of doing so certainly isn't mine.) Anyone care to suggest an optimization?

I'm working on a document where I need to typeset something in Old English. Particularly, I need to type an eth. There are at least two Old English fonts for TeX available, my pick being Computer Modern Old EnglishI'm surprised to find that my TeX distribution doesn't include (that I can find) any Old English fonts.

A month ago I didn't have one, today it's 150 pages ( Read more... )
