I gave an introductory talk on Gentoo at a local BarCamp called MinneBar a couple of months back, and the videos were just posted online. The sound isn’t perfect but it’s perfectly understandable. Oddly, this is the first time I’ve ever given a formal talk on Gentoo in nearly 10 years of working on it.
The slides are pretty tough to read from the video, so I also uploaded them to Slideshare. I updated and heavily customized the same “Intro to Gentoo” slide deck that’s been floating around for years. It still could stand to lose a whole lot more text, and hopefully I can optimize it further if I give it again.
