Software Error Likely Killed MGS Spacecraft 199

Posted by kdawson from the off-by-one dept.
Aglassis writes "NASA investigators have determined that a software update performed in June of 2006 may have doomed the 10-year-old spacecraft. Apparently the software error caused the solar arrays to drive against a mechanical stop which then forced the spacecraft into safe mode. Unfortunately, after that the spacecraft's radiator was pointed at the sun which overheated the battery and destroyed it. Contact was lost with the Mars Global Surveyor spacecraft in November 2006. NASA will form an internal review board to determine formally the cause of the loss of the spacecraft and what remedial actions are needed for future missions."

Water Cooling Computers With A Swimming Pool 241

Posted by CowboyNeal from the take-your-pc-for-a-dip dept.
guzugi writes "This is a project I have been working for several months and been hypothesizing for much longer. The basic idea is to shortcut the need for an air conditioner when cooling multiple computers. Swimming pool water is pumped into the house and through several waterblocks to effectively cool these hot machines. This greatly reduces noise cooling requirements."

Best Sitting Posture Is Not Straight Up 291

Posted by kdawson from the try-typing-in-that-position dept.
An anonymous reader writes, "Researchers at Woodend Hospital in Aberdeen, Scotland used a new form of magnetic resonance imaging to collect images from 22 healthy volunteers, who assumed three different sitting positions: slouching posture in which the body is hunched forward, an upright 90-degree sitting position, and a relaxed position where the subject reclined backward 135 degrees. They concluded that the reclined position is the best, and the forward slouch the worst." From the article: "'We were not created to sit down for long hours, but somehow modern life requires the vast majority of the global population to work in a seated position,' Dr. Bashir said. 'This made our search for the optimal sitting position all the more important.'"

IE7 Blocking Google Image Search? 253

Posted by kdawson from the play-nicely-now dept.
An anonymous reader writes, "I just tried a Google Image Search in IE7 for the first time. Whenever I click on an image, my browser tells me in big bold letters, "This is a reported phishing website." Try it yourself: make sure automatic phishing detection is turned on and do an (adorable) image search; click on one of the result thumbnails. MSN Live Image Search has no such issues. Insert Microsoft evil conspiracy theory here." I get this behavior under IE7, Win XP Pro, SP2, Parallels, Mac OS X.
