UW Study Examines Gender Bias in Stock Images (Aug 30, 2015)
Researchers from the universities of Washington and Maryland analyzed gender bias in online image results, and their study found a systematic underrepresentation of women. In occupations that have the same number of women and men, the researchers report women only account for 45 percent of the search images. Moreover, women in the images sometimes appear highly sexualized. When study participants were asked to identify which images showed a more professional and appropriate-looking person for a ...Read More
Purdue University Researcher Invents Fake Password Technology to Confuse Hackers (Aug 29, 2015)
Purdue University Information Assurance and Security group researchers have developed ErsatzPasswords, a security system that makes it much harder for hackers to obtain usable passwords from a leaked database. Hackers "will still be able to crack that file, however the passwords they will get back are fake passwords or decoy passwords," says Purdue doctoral student Mohammed H. Almeshekah. ErsatzPasswords adds an additional step to traditional encryption methods.

Why Women in Tech Came to a "Halt" (Aug 7, 2015)
Nowadays, two of the best-known women in computer science might just be characters on a TV show. On AMC's 1980s-set drama "Halt and Catch Fire," friends Cameron and Donna run an upstart computer company called Mutiny. One might assume that in the early 1980s, women in computer science were a rarity, but that's not true. "In the '80s, there were more women getting degrees in computer technology than there are now, which is mind-blowing," Kerry Bishe (Donna) said on the set of the show. A National...Read More

The Athena 2.0 project reports that women in mid-level IT positions experience several influences that contribute to them leaving the profession. In many cases, t...Read More
Nowhere to Hide (Aug 1, 2015)
Criminals operating under the cover of darkness had better watch out. Computer scientists have developed a technology that can recognize a person’s face and identify them in poor lighting and even total darkness. It uses a "deep neural network system" that works a little like the human brain to analyse infrared images and match them with ordinary photos.Computer scientists at the Karlsruhe Institute of Technology, Germany, developed the new facial recognition technique that reads a person’s ...Read More
This New 3D XPoint Memory Could Last Forever (Jul 31, 2015)
Intel and Micron this week unveiled a new type of memory they plan to mass produce that is purportedly 1,000 times faster than NAND flash and has 1,000 times the endurance. One thousand times the endurance would be about one million erase-write cycles, meaning the new memory would last pretty much forever. By comparison, today's NAND flash lasts for between 3,000 and 10,000 erase-write cycles. With wear-leveling and error correction software, those cycles can be improved upon, but still don't ge...Read More
