Angel's Egg - the home page of Eduardo Ochs (a.k.a. Edrx)

Welcome! I'm a mathematician, logician, categorist and type-theorist who used to do computer programming and Free Software activism in his spare time... I have a Free Software project that I consider extremely important, and I have decided that I have to spend a few years outside of the academic world working on day jobs related to Free Software in order to concentrate better on it and make it as usable and well-known as possible.

The world does need simpler ways to understand Type Theories and categorical models, true, but it desperately needs to reduce computer illiteracy and other illiteracies and to realize the importance of Free Software and Free Information. The Eev Project is an effort against illiteracies, and it has stayed underground for far too long; type theory will have to wait.

(I've been doing less maths-related work recently and more activism. Here's why.)

2017: pages with links about the art exhibitions Queermuseu and La Bête.

(Update: I did spend several years in the "real world", but things didn't work out there...
I now work at PURO, a small countryside campus in the wild east of the state of Rio de Janeiro).

2008: I (sort of) survived my stay in the real world. Links: , LLaRC, PURO, GAN, concurso, seminars...

(2008dec01:) I spent the last 6 years being quiet, trying to behave. It didn't work.
I got ill many times, almost starved, almost lost teeth, almost blew myself up.
If you tried to get in touch with me during this time and I didn't answer, sorry - can we try again? 8-|
(2014-2018): my self-esteem sank to abyssal levels and I disappeared again.

December, 2007: I moved to São Paulo (São Caetano, actually) and I am working at Omnisys. (*)

2007nov07: weird news - a round table that I was invited to speak at turned out to be about Digital TV, Digital Radio, Free Software and Education - and I haven't watched any TV, or listened to the radio, in at least 5 years... the details, and my notes (in Portuguese) are here.

October, 2007: I am no longer working on DaVinci and IUP. I am working a tiny fraction of my time on Plurall, and I am finishing several important personal projects (BlogMe, Dednat4, DNC, eev, peek.lua). Expect releases soon. Cheers.

July, 2007: I am currently working full-time (or sort of) on IUP and on the DaVinci Project.

Quick index:
[eev] eev, that is a tool for automating almost everything,
[dednat4] dednat4, for typesetting trees and categorical diagrams,
[dednat4] my outdated page on categorical semantics,
[blogme] BlogMe, that generates the html of these pages,
[llangs] a list of all of my little (extensible) languages,
[gab] gab, a calculator with quantifiers,
MiniForth and RubyForth (by Marc Simpson)
other programs in Lua and Forth,
other things related to Emacs,
my pages on Tcl/Tk/Expect, Icon, and (La)TeX,
[rrj] my rape recovery journal (is no longer secret),
how to contact me (and my CV),
my pages on (micro)politics, veganism and the CoE,
literature, music, movies, webcomics, my mother's PhD thesis,
my old personal pages.

I used to be just in a war against the macho world -
now I am explicitly genderfreaky/TG/TS
(but I'm too busy to change what I see in the mirror)

(Note, 2007mar14: sorry, this site is currently a mess... I'm rewriting parts of the tools that I use to generate the pages in html - BlogMe and TH -, I'm adding an interactive mode to Dednat4, and I'm looking for a job...)

The eev project, computer tourism, and related topics (about making free information easier to use):

2018may31: (find-eev-quick-intro) is now the standard starting point of eev. The pointers below are older.

The best starting points about eev are these screencasts:
 (YT, MP4) eepitch: a way to control shell-like programs from Emacs (best)
 (YT, MP4) An introduction to eev2 (long, not so good)
 (YT, MP4) Uma introdução ao eev2 (in Portuguese, longer)
The YT links point to youtube, where the videos are in a reduced resolution; the MP4s are better.

The other best starting points are the sandboxed tutorials. They are meant to the used from inside Emacs - the tutorials 00, 1, 2, and 5 explain how - but they are quite readable from the web. These are the main ones:

. 00. (find-eev-quick-intro)

September 11, 2001 - the inevitable happenned in an oh so glorious way
If you treat everybody else as an enemy you get an ulcer.
The American ulcer is bleeding (in the form of the falling of the twin towers), and it is no longer possible to just take a pill, find something external to blame, and forget about the problem.

2003mar20: Oh, no - they're destroying another country -
What we need is a world without the United States.
What have you been doing for that?
