At several conferences a year, I teach the Young Coder's classes to groups of children ages 12 and up. These classes are a chance for children to get exposure to the ideas of programming as well as giving them a chance to get comfortable in coding environments.
For more information about running one of these classes yourself, check out Barbara Shaurette's Github repo. If you're interested in me running a class, connect with me on Twitter to see if I'm available.
Several times a year, I post tutorials on YouTube for beginner developers (I used to do them in-person, but they were killing my back). Older videos are recordings of live classes that I held, but recently I've been moving to simply recording them on my own and posting them.
