I just can't wait for the Ubuntu 6.10 "Edgy Eft" due to be released on October 26. Some people wanting long-term support will want to stick with the current 6.06, but others should look here for release notes. It will include among other things Firefox 2.0, which will be released generally today. See GetFirefox.com in a few hours (from noon, Eastern US time.)
Mark Shuttleworth, founder of the Ubuntu Foundation, talks about Ubuntu Linux in the developing world and collaborative educational texts in a podcast/broadcast of the BBC Radio show Digital Planet. Download here. (There's also a good article on the social benefits of a new wifi hotspot in Salamanca, Chile in the same download.)
And see the Shuttleworth Foundation site and its wiki, too.
October 25. OK, I couldn't wait. I upgraded my Ubuntu installation last night. I'm sure there will be a few more things to install later -- there's a button that tells you if there are new software versions available -- but I really like it, especially Firefox 2.
