This is the presentation I gave about Emacs Org-mode for the GNU Hackers meeting in Paris, august 2011. Thanks to Ludovic Courtès for his kind invitation, to the audience for the nice questions and to IRILL/Jason Self for providing these videos. Check all presentations and videos out here:
The first 8 minutes are a general introduction of Org-mode, similar to the one I gave in FOSDEM.
From there, I do a small interactive demonstration of basic Org features: headlines, TODO keywords, agenda views, clocking tasks and clock reports, properties, HTML, LaTeX, OpenDocument Format exports, tables, Babel source code manipulation, etc.
Demonstration is done using Emacs 23.3 and Org 7.7 and no configuration at all.
The presentation ends up with "The OrgFather" -- see lumiere.ens.fr/~guerry/theorgfather.html
