nil0lab writes "In a case of 20/20 hindsight, Princeton DARPA Grand Challenge team member Bryan Cattle reflects on how their code failed to forget obstacles it had passed. It was written in Microsoft's C#, which isn't supposed to let you have memory leaks. 'We kept noticing that the computer would begin to bog down after extended periods of driving. This problem was pernicious because it only showed up after 40 minutes to an hour of driving around and collecting obstacles. The computer performance would just gradually slow down until the car just simply stopped responding, usually with the gas pedal down, and would just drive off into the bush until we pulled the plug. We looked through the code on paper, literally line by line, and just couldn't for the life of us imagine what the problem was.'"

An anonymous reader writes "Leopard's Finder has a glaring bug in its directory-moving code, leading to horrendous data loss if a destination volume disappears while a move operation is in progress. This author first came across it when Samba crashed while he was moving a directory from his desktop over to a Samba mount on his FreeBSD server."

Kelson writes "The Internet Explorer team has updated the installer for IE7. Mostly they've adjusted a few defaults and updated their tutorials, but one change stands out: The installer no longer requires Windows Genuine Advantage validation. Almost a year after its release, IE7 has yet to overtake its predecessor. Was WGA holding back a tide of potential upgrades, or did it just send people over to alternative browsers?"

brajesh writes to tell us that Skype has blamed its outage over the last week on Microsoft's Patch Tuesday. Apparently the huge numbers of computers rebooting (and the resulting flood of login requests) revealed a problem with the network allocation algorithm resulting in a couple days of downtime. Skype further stressed that there was no malicious activity and user security was never in any danger.

Originally developed at Queen's University, Ontario, they hope to sell it to advertisers to allow them to monitor how many people look at their ads. Admittedly they are trying more benign stuff too like better hearing aids, but I doubt that will make up for movie posters that make a song and dance whenever you glance their way."

Nonfinity writes "A public iris scanning device has been proposed in a patent application from Sarnoff Labs in New Jersey. The device is able to scan the iris of the eye without the knowledge or consent of the person being scanned. The device uses multiple cameras, captures multiple images, and then selects the best image to process."
