jasonbrown writes "Apple on Thursday began removing another category of apps from its iPhone App Store. This time, it's not porn, it's Wi-Fi. Apple removed several Wi-Fi apps commonly referred to as stumblers, or apps that seek out available Wi-Fi networks near your location. According to a story on Cult of Mac, apps removed by Apple include WiFi-Where, WiFiFoFum, and yFy Network Finder."

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."

Milan Karki, 18, who comes from a village in rural Nepal, believes he has found the solution to the developing world's energy needs. A solar panel made from human hair. The hair replaces silicon, a pricey component typically used in solar panels, and means the panels can be produced at a low cost for those with no access to power. The solar panel, which produces 9 volts (18 watts) of energy, costs around $38 US (£23) to make from raw materials. Gentlemen, start your beards. The future of hair farming is here!

ArfBrookwood writes "Every year, I write a Christmas Letter and send it to about 50 people, and every year, it's different. One year it was just the word blah blah blah over and over with keywords, one year I made papercraft wallets with full color cards and money in them, another year I created a Christmas Letter writing contest that instructed the recipients to create our Christmas Letter for us and we awarded prizes to winners, last year, I took a fake retro photo of my family, Inkscaped/GIMPed in a chemistry set and some wall art, printed it onto CD covers, and burned retro Christmas songs onto digital vinyl and sent everyone in the family what looked like a miniature Christmas album. Last week, I came into the possession of 78 2GB USB drives. I have already taken the time to wipe them clean and reflash the memory so they are blank slates." Now, Arf's looking for suggestions for how to best use all these drives; read on for more.
