From August 31st to September 4th, will take place the Ubuntu Developer Week, lots of speeches on irc channel #ubuntu-classroom at Freenode. As usual, they are only in English but, this time, a team of volunteers will translate the questions of those participating in the event. Right away, Siegfried (you’re awesome!) joined for translate from Catalan, so now you know, those who are interested in and with low English knowledge, have an unique opportunity to ask the developers things related to Ubuntu.
On the wiki there is the schedule with the subjects to treat, from bug triaging to writing secure software or profit on Launchpad.
