Introduction to Fonts [www.anaesthetist.com]

For a website about anaestetics, it has a lot of useful developer tutorials on perl and other things.

This page rates a mention since I find that so many developers have little understanding about the basics behind fonts. Developers who started with Mac's in the early 90's have more than most for obvious reasons.

Even if you don't follow the maths behind bezier curves etc., you will learn a lot of usefull terminology.
