The magical number of times to overwrite data on a hard disk to render it unrecoverable is seven.

No, you idiot!

The actual number is one. I'm not sure if that is "surprising" per se, but a lot of people seem to bring out that number seven for some reason. (Probably because of the DoD's intentional paranoia.)

Let me attach a quick caveat to that, though. For you to call data "recovered," you have to able to recover a usable amount of data (more than just 1 byte), with no foreknowledge of the previous data.

Mid level formats (zeroing) are only required to run once to render 99.9% of data irrecoverable.

fan cools room

one of the great summer myths is that a fan will cool a room. a fan cannot cool a room... it can only cool the people who are sitting in the room by evapourating their perspiration

a fan cools you by removing a layer of warm air that would normally sit next to your skin. this is fine in the middle of summer, but could kill you in the middle of winter.
the technical term for this is 'wind chill'. antartic and himalayan travellers have found they can survive perfectly well, bare-chested, in temperatures as low as -40ºC as long as there is absolutely no wind blowing. but if there is the slightest breath of wind, they have to cover up immediately.

If someone sends you an urgent email, that has anything whatsoever to do with Microsoft, AOL, a virus, or a kid with cancer; instructing you to forward it to everyone you know, YOU MUST COMPLY!!!

This is false. For that matter, I would think it's safe to assume there has never been an email that warrant's such an action.

Originating from the french word "toque", us goddamn french canadians changed it to "tuque". Then you goddamn other canadians changed it to "touque", since you english people like to steal words like "crepe" and "cravate" and add your silly little english meanings to them. Sure, us Quebecers ruined the french language, but we're fucking proud of it. Stop stealing the words we ruined.

Assholes.
