DavidB is generally awesome, that said I just watched this its kinda of meh, maybe 5-9m of good stuff, if haven't seen his other talks, I'd recommend them first, unless you have particular interest in patent legal suits, and indexing code for basic patterns via a library of functions (grep/glob/etc), ie its basically using stdlib collections w/ files to build a vfs grep/stats lib, w/ py 2.3 while coding on a desert island so to speak. his other talks cover a wide range of subjects, their probably all better imo.
