Read my articles on Mac OS X related topics, or download my software packages. Most of them were born from my own needs, none of them claims to be a universal solution to everybody's problems! Here are some highlights:

Aquamacs Emacs: The Emacs that Mac users love.

Postfix on OS X: How to send e-mail from your laptop (or home) with your own, independent mail server.

Legacy software for Atari TOS based systems including égale and a content management server (SiCoPs).

Please also note my projects in Language Technology.
