Is the iPod Shuffle Playing Favorites?
marksilverman writes "Steven Levy at Newsweek is reporting that his iPod Shuffle seems to favor certain songs. Is Apple receiving kickbacks to promote certain artists? Apple denies it, of course, and Levy had the good sense to ask a mathmatician and a cryptographer who explained that it's probably just humans finding patterns where there are none." Less neurotically, both CNet and PCWorld have discussions of the Shuffle's interior spaces.
Computers can't generate true random numbers (ok, at least I don't know of any current methods) but only pseudo random numbers. There's a precise mathematical description that gets you from one number to the next.
Who knows, maybe Apple uses the meta data for a song to determine the random order (anyone hack it yet and finding the algo?) and some people just get "lucky" like prof John Allen Paulos explained in the article. You might happen to flip 6 heads in a row (despite being a 1 in 64 chance of it happening) and you might get 6 songs from an artist in a row.
Sounds to me that it's a conspiracy theory at best.

If you have any audiobook or spoken word that have proper metadata, they will never be selected in shuffle mode. While this can be handy for not falling onto a 20 minute chapter of a book randomly, it also makes it a bit more difficult to create cut-ups, or experiment with random spoken words when you want to: you must retag the tracks.
This is also useful to take long tracks out of random selection. A friend retagged Pink Floyd's 23 minute long 'Echos' as a book after getting pissed off that his Shuffle always seemed to select it.
When looking at the candies through the side of the glass jar, the first thing you notice is that the distribution of red and green candies doesn't look evenly distributed at all. Instead, there are lots of areas where many red candies are adjacent, and lots of areas where many green candies are adjacent.
For a long time, many people thought there must be some kind of static electrical effect present that was causing candies of the same color to tend to stick together. Eventually, however, some statisticians did the math and found that there was no such effect at play -- in a completely random system, such "blobs" of like colors are inevitable. Indeed, a jar of candy with no such blobs would be a bit suspect -- what are the chances of the red and green candies always pairing up so that no groupings occur?
To put it another way: it's all in your heads, guys.
I don't care if it's 90,000 hectares. That lake was not my doing.
I noticed that screens towards the top end of the scale seemed to show up more than screens towards the bottom (ie. if you had twenty images, images one to ten would should up more than eleven to twenty). I did some sort of multipass algorithm to stop this happening - I forget exactly what I did now and the source is lost, but I definitely had to change things to make it acceptable.
