Security and the statistics of rare events

@#11
math degree and ya didn't get it eh... erm can i ask where it was you were at college... just kidding ;)

here it is:

there is a disease that affects 1 in a million people.
that means that only 1 person out of a sample of a million have it.

you have a test that is 99% accurate.
that means that if you test all 1million people, there is still going to be 1% that get the wrong result
i.e. that means that 10,000 people are going to get a notice that tells them they have the disease even though they don't have it.

strictly speaking cory could have said "10,000 times out of 10,001", rather than "9,999 out of 10,000" but you get the point; because of 10,001 people who got a positive result, 10,000 of them got the wrong result.

Graffiti Research Lab, the movie

hmmm i have to agree with the sentiment of #2.

the idea that this contains any of the sincere and authentic authority-challenging that goes on in serious graffiti is a bit sad.

it can be argued that their self-publicity subverts the capitalist tools of corporate america but doesn't their friendship with all sorts of institutional bodies (i would include MOMA and eyebeam) pretty much contradict that?

essentially this kind of work exists in authoritarian societies (like america has become) so that the authorities can say: "no you're wrong, we *do* allow dissent, look at what we let GRL get away with!"

well, clearly #4 *ain't* a designer otherwise he would have noticed that wrinkles and baggy folds were very much a theme of the collection and so yes it probably WAS deliberate
