The entire video is simply a terminal session, not even doing any curses-like. Why not just paste the terminal session output in a <pre> block? Would have saved me 1:15.

Also, bug report: If you seek to very close to the end, the timer shows 1:21 and keeps counting with nothing happening on the screen... I was wondering why he didn't hit enter after typing "ls matte" and let the timer run to 2 minutes...
