I've been hanging around with Debian people like damog, vorlon (who gave a nice talk in spanish on tuesday, ashaming both me and nanda, the brazilians who gave talks in english while the gringo talks in spanish =D) and gwolf. There are also lots of people with perl, python, FreeBSD and Gentoo background.
I've spoken about Free Software in Brasil and about Python/GTK+/Glade. I'm still amazed that most people I've met here speak english. This has made it easy for me to live here, because when my portuñol fails I can always talk in english.
I've also taken the time to submit one more proposal for this year's FISL's call for papers. I suggest you submit yours quickly, because they're due on february 28th! =)
