Will Scott, the American that spent a semester teaching computer science at the Pyongyang University of Science and Technology, spoke about his experiences this week at the Chaos Computer Club’s annual conference in Hamburg.

Scott, who has just returned from the second trip to PUST, went into detail on the IT environment at the university, availability of the Internet, access to computers and cell phones, and his observations on Red Star Desktop 3.0, the latest version of North Korea’s home-grown Linux operating system.
