The video for my 2013 PyCon talk, "EduPsych Theory for Python Hackers, " is up. It's 27 minutes and 56 seconds long, and you can view the subtitled version

(Disclaimer: I'm transcribing my own talk about a week after having given it, but I am deaf, so I'm typing this out through a combination of residual hearing, remembering what I said last Thursday, lipreading myself in the video, and reading slide content. It's probably 98% accurate; patches welcome on Universal Subtitles.)
