- The master password for Facebook, which could be used to log into any Facebook account, was “Chuck Norris”. Don’t worry – they don’t use it anymore. And anyway, Chuck Norris doesn’t use Facebook, because if you ever read Chuck Norris’ status, it’d only say one of these various facts.

- SAS, the well-known developer of statistical software, has been named Fortune’s Best Company to Work For.
- A graduate student at the University of Manitoba failed comprehensive exams twice but was reinstated due to “test anxiety.”
