TI-Nspire Hack Enables User Programming 88

An anonymous reader writes "Texas Instruments' most recent, ARM-based series of graphing calculators, the TI-Nspire line, has long resisted users' efforts to run their own software. (Unlike other TI calculator models, which can be programmed either in BASIC, C, or assembly language, the Nspire only supports an extremely limited form of BASIC.) A bug in the Nspire's OS was recently discovered, however, which can be exploited to execute arbitrary machine code. Now the first version of a tool called Ndless has been released, enabling users, for the first time, to write and run their own C and assembly programs on the device. This opens up exciting new possibilities for these devices, which are extremely powerful compared to TI's other calculator offerings, but (thanks to the built-in software's limitations) have hitherto been largely ignored by the calculator programming community."

NASA To Cryogenically Freeze Satellite Mirrors 47

coondoggie writes "NASA said it will soon move some of the larger (46 lb) mirror segments of its future James Webb Space Telescope into a cryogenic test facility that will freeze the mirrors to -414 degrees Fahrenheit (~25 K). Specifically, NASA will freeze six of the 18 Webb telescope mirror segments at the X-ray and Cryogenic Facility, or XRCF, at NASA's Marshall Space Flight Center in Huntsville, Alabama, in a test to ensure the critical mirrors can withstand the extreme space environments. All 18 segments will eventually be tested at the site. The test chamber takes approximately five days to cool a mirror segment to cryogenic temperatures."

Researchers Claim To Be Able To Determine Political Leaning By How Messy You Are 592

According to a study to be published in The Journal of Political Psychology, you can tell someone's political affiliation by looking at the condition of their offices and bedrooms. Conservatives tend to be neat and liberals love a mess. Researchers found that the bedrooms and offices of liberals tend to be colorful and full of books about travel, ethnicity, feminism and music, along with music CDs covering folk, classic and modern rock, as well as art supplies, movie tickets and travel memorabilia. Their conservative contemporaries, on the other hand, tend to surround themselves with calendars, postage stamps, laundry baskets, irons and sewing materials. Their bedrooms and offices are well lit and decorated with sports paraphernalia and flags — especially American ones. Sam Gosling, an associate professor of psychology at the University of Texas at Austin, says these room cues are "behavioral residue." The findings are just the latest in a series of recent attempts to unearth politics in personality, the brain and DNA. I, for one, support a woman's right to clean.
