An anonymous reader writes "This article has a very interesting description of the algorithms behind the ghosts in Pac-Man. I had no idea about most of this information, but that's probably because it's difficult to study the ghosts when I die every 30 seconds. Quoting: 'The ghosts are always in one of three possible modes: Chase, Scatter, or Frightened. The "normal" mode with the ghosts pursuing Pac-Man is Chase, and this is the one that they spend most of their time in. While in Chase mode, all of the ghosts use Pac-Man's position as a factor in selecting their target tile, though it is more significant to some ghosts than others. In Scatter mode, each ghost has a fixed target tile, each of which is located just outside a different corner of the maze. This causes the four ghosts to disperse to the corners whenever they are in this mode. Frightened mode is unique because the ghosts do not have a specific target tile while in this mode. Instead, they pseudorandomly decide which turns to make at every intersection.'"

I am not even sure what it takes to heat a small hotplate, but I am sure it is more than 5V. It looks like the guy tied together around 30 USB cables powered by his PC to power this small hotplate. But believe it or not, it seems to have cooked the meat perfectly."

California has once again been blessed with another steampunk convention, this time to be held in Emeryville, CA on March 12-14 as the "Nova Albion Steampunk Exhibition." This year's event promises to mix in much more of the DIY/maker flavor for a greater hands-on feel. Steampunk has been gaining much broader appeal in recent months with the continued growth of maker communities, and the many delightful varieties of music and literature. The con will feature, among other things, a 2 day track of 2-hour how-to, hands-on, and interactive workshops gear towards makers, DIY-ers, mad scientists, and evil geniuses. Of course, if you are an evil genius you probably don't need a workshop except as a gathering for potential test subjects.

Today the average computer sells for $701, while the average Windows machine sells for only $515. Still, Macs only make up 8.7% of PC sales. But is that really such a bad position to be in? Consider an Apples to Apples, that is, Macs to iPhones comparison: the iPhone takes only a sliver of the phone market but a much larger share of the profits."

An anonymous readerwrites "On Friday the wonderfully customer centric AirTran decided to remove a family of 9 US born Muslims after a comment between two family members regarding how close to the Jet engine they had been seated. The wonderful part is that after the FBI cleared the family 2 hours later, AirTran refused to fly the family, and refused to rebook them on their way from Washington to Orlando, Florida. The family purchased additional tickets on US Airways later that day, after AirTran requested that the irate father be escorted from their booking podiums by security. This whole story highlights the pathetic customer service we are getting from the Airlines these days — they actually treat us like criminals first and ask questions later. Just don't get me started on Delta." It's nice to see that stupidity still knows no bounds.
