sk8pmp writes with news that iFixit, a website known for Apple gadget teardowns and repair guides, is expanding into the game console market, launching a series of troubleshooting and repair guides to help gamers fix their own machines. They're also starting to sell replacement parts and the tools necessary to work on them. "Right now there are repair guides for 24 gaming consoles, including 206 repairs and upgrades. Some of these fixes deal with major issues, such as the infamous Red Ring of Death from the Xbox 360, but others are simpler. For instance, right now there is no easy way to clean out the fans inside your console. 'I think this is probably the number one cause of overheating these days now that manufacturers have mostly gotten their act together,' Wiens said. 'This is routine maintenance, and it's mind-boggling that the manufacturers don't provide people with an easy way to open the case up and blow it out.' You'll also learn how to replace broken LCD screens on your portables, replace the motherboard on your PlayStation 3, and do just about anything else you might want to do to these systems, from the simple to the harrowing."

cremeglace writes "Scientists say they may have discovered a way to develop cool new vaccines — and they mean that literally. By replacing essential genes in a mammalian pathogen with their counterparts from Arctic bacteria, they have created strains that provoke a protective immune response in mice, but that don't spread to the warm parts of the body where they could do serious harm. The team hopes that the method will lead to a new generation of vaccines for major bacterial diseases such as tuberculosis."

Ant notes a piece up on WBUR Boston addressing theories to explain the universal human experience that time seems to pass faster as you get older. Here's the 9-minute audio (MP3). Several explanations are tried out: that brains lay down more information for novel experiences; that the "clock" for nerve impulses in aging brains runs slower; and that each interval of time represents a diminishing fraction of life as we age.

longacre writes "An amateur video of the 1986 Space Shuttle Challenger explosion has been made public for the first time. The Florida man who filmed it from his front yard on his new Betamax camcorder turned the tape over to an educational organization a week before he died this past December. The Space Exploration Archive has since published the video into the public domain in time for the 24th anniversary of the catastrophe. Despite being shot from about 70 miles from Cape Canaveral, the shuttle and the explosion can be seen quite clearly. It is unclear why he never shared the footage with NASA or the media. NASA officials say they were not aware of the video, but are interested in examining it now that it has been made available."

Glyn Moody has a thoughtful piece taking a long look at the never-ending battle between pragmatists and purists in free and open software. "While debates rage around whether Mono is good or bad for free software, and about 'fauxpen source' and 'Faux FLOSS Fundamentalists,' people are overlooking the fact that these are just the latest in a series of such arguments about whether the end justifies the means. There was the same discussion when KDE was launched using the Qt toolkit, which was proprietary at the time, and when GNOME was set up as a completely free alternative. But could it be that this battle between the 'purists' and the 'pragmatists' is actually good for free software — a sign that people care passionately about this stuff — and a major reason for its success?"
