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.)

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)
Between 2004 and 2008 I tried to work as a professional programmer,
but I ended up failing miserably - mostly because I was not
thick-skinned enough.
My plan was to earn money to move to London and do the
training on Alexander
Technique at Karen Wentworth's school, but I had to put that on hold.
Some links:
2005-2006: worked at Vivo.
July-October, 2007: worked full-time on IUP and on
the DaVinci Project.
October-December, 2007: worked on Plurall.
November, 2007: I gave a talk in a round
table about Digital TV, Digital Radio, Free Software and
Education.
In December, 2007 I moved to São Paulo (São Caetano, actually)
and started working at Omnisys.
In February, 2008 I was fired.
In April, 2008 I applied to a position at UFF.
I started working there in January, 2009.

The eev project, computer tourism, and related
topics (about making free information easier to use):
I used to call eev a "tool for automating almost everything" and
"my project to save the world with Free Software". In more concrete
terms, eev is a library for Emacs that lets us create executable logs
of what we do in a format that is reasonably easy to read and to
modify, and that lets us "play back" those logs step by step in any
order - for example, like in this video.
The main starting points for eev are:
this introduction
with lots of links in its git
repository,
EmacsConf2019
My presentation at the EmacsConf 2019
(video,
slides), and
EmacsConf2020 the one at the
EmacsConf 2020, that was more technical (more videos).
(find-eev-quick-intro) this sandboxed tutorial that explains
all the main features of eev.
The recommended way to install eev is with M-x list-packages, as in this video (MP4).
(find-emacs-keys-intro) lists the most important keys
of eev and emacs.
(find-eev-intro) is an index to all sandboxed
tutorials, including many obsolete ones.
The main ones are:
If you don't even know how to use M-x
in Emacs,
then start by (find-windows-beginner-intro).
Eev is now an ELPA package! Its ELPA page is here.
You can install it from Emacs with M-x list-packages (even
on M$ Windows!)
and then run the tutorial with M-x eev-beginner .
A tutorial for M$ Windows users.
The main tutorial starts
with (semi-obsolete) installation instructions for beginners
(like in this video)
that create a shell script "~/eev " that starts emacs, loads
eev, and opens the quick intro.
For a totally non-technical introduction to eev, read this.
For non-technical introductions in Portuguese read this and this.
(find-escripts-intro) explains what these "executable
logs" ("e-scripts") are;
its section "3. Sharing"
explains some of the motivation,
its section "4. How to read
an e-script" dissects a small example;
http://angg.twu.net/e/lua-intro.e
is a much bigger example of an e-script;
its section "5. Tools for
writing e-scripts" discusses how to take (executable) notes.
An e-script is usually made of:
free-form text,
hyperlinks (including `to 's), and
code for shell-like programs (as shown in
this
video).
Here are some screencasts:
The last third of my EmacsConf2019 video is a screencast.
(MP4) Como usar o find-here-links-3 (2020apr06, in
portuguese)
(MP4) Sobre rodar programas em terminais
(2020apr07, in portuguese)
(MP4) How to
install eev, for beginners (2016, without sound)
(MP4) How to
install eev, for beginners (2016, without sound)
These two are based on (find-three-main-keys-intro):
(YT, MP4) The three main keys of eev (2019aug09, in english, sound out of sync)
(YT, MP4) The three main keys of eev (2019aug09, in portuguese, sound out of sync)
These ones were made before I implemented the "(find-*-intro)"s:
(YT, MP4) eepitch: a
way to control shell-like programs from Emacs (2013jan16,
good)
(YT, MP4) An introduction to
eev2 (2012nov11, long, not so good)
(YT, MP4) Uma
introdução ao eev2 (2012nov15, in Portuguese,
longer)
The YT links point to youtube, where the videos are in a reduced
resolution; the MP4s are better.
The git repository is here: https://github.com/edrx/eev
See (find-eev-install-intro) for alternative ways to
install eev.
The eev mailing list
(and its archives).
Some information on how blogme3
htmlizes ascii files with elisp hyperlinks.
Some old versions of eev only supported "«...»"s correctly in unibyte buffers;
recent versions of eev are UTF-8 clean. See the comments in eev-codings.el.
The file eev-load.el can be used
as a guide to the source files of eev.

executáveis") no PURO/UFF.
I'm learning Idris. Here is my eev-ized version of its
tutorial.
This will be an eev-based tutorial on Org
when it grows up: (find-org-intro)

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.

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