Thanks. Glad you liked it enough to remember :) Indeed, I've just checked and I still have the TeXmacs files for the "polycopié du cours de Processus Discrets".

Thanks. Glad you liked it enough to remember :) Indeed, I've just checked and I still have the TeXmacs files for the "polycopié du cours de Processus Discrets". The main developer was in Orsay at the same time I was there 2006, for mixed circumstances I've started to interest me to that software at the same time. I should say at the beginning I was attracted to TeXmacs not as a user but because it is a very complex piece of software which is very fun to hack on (choose your language: Scheme or C++).
