The web page of David T. O'Toole

You have discovered my web page. I keep some unfinished essays and various notes here, mainly for the purpose of sharing with friends. There are also various links to friends' websites and to other things I've done on the internet.

My name is David T. O'Toole. I program computers and advocate Free Software. I use a wonderful program from the Free Software Foundation called GNU Emacs and have had the good fortune to be involved in its amazing and colorful community for nearly two decades.
