theodp writes Writing in Vanity Fair, U.S. Secretary of Education Arne Duncan marvels that his kids can learn to code online at their own pace thanks to "free" lessons from Khan Academy, which Duncan credits for "changing the way my kids learn" (Duncan calls out his kids' grade school for not offering coding). The 50-year-old Duncan, who complained last December that he "didn't have the opportunity to learn computer skills" while growing up attending the Univ. of Chicago Lab Schools and Yale, may be surprised to learn that the University of Illinois was teaching kids how to program online in the '70s with its PLATO system, and it didn't look all that different from what Khan Academy came up with for his kids 40 years later (Roger Ebert remarked in his 2011 TED Talk that seeing Khan Academy gave him a flashback to the PLATO system he reported on in the '60s). So, does it matter if the nation's education chief — who presides over a budget that includes $69 billion in discretionary spending — is clueless about The Hidden History of Ed-Tech? Some think so. "We can't move forward," Hack Education's Audrey Watters writes, "til we reconcile where we've been before." So, if Duncan doesn't want to shell out $200 to read a 40-year-old academic paper on the subject (that's a different problem!) to bring himself up to speed, he presumably can check out the free offerings at Ed.gov. A 1975 paper on Interactive Systems for Education, for instance, notes that 650 students were learning programming on PLATO during the Spring '75 semester, not bad considering that Khan Academy is boasting that it "helped over 2000 girls learn to code" in 2014 (after luring their teachers with funding from a $1,000,000 Google Award). Even young techies might be impressed by the extent of PLATO's circa-1975 online CS offerings, from lessons on data structures and numerical analysis to compilers, including BASIC, PL/I, SNOBOL, APL, and even good-old COBOL.

EwanPalmer sends a followup to a story from last year about a team of Siberian scientists who recovered an ancient wooly mammoth carcass. It was originally believed to be about 10,000 years old, but subsequent tests showed the animal died over 43,000 years ago. The scientists have been surprised by how well preserved the soft tissues were. They say it's in better shape than a human body buried for six months. "The tissue cut clearly shows blood vessels with strong walls. Inside the vessels there is haemolysed blood, where for the first time we have found erythrocytes. Muscle and adipose tissues are well preserved." The mammoth's intestines contain vegetation from its last meal, and they have the liver as well. The scientists are optimistic that they'll be able to find high quality DNA from the mammoth, and perhaps even living cells. They now say there's a "high chance" that data would allow them to clone the mammoth.

symbolset writes "As reported on The Verge, many people are experiencing freezing, rebooting and battery problems on their new Windows Phone 8 devices. This WP8Central thread shows many of the issues. Affected devices include Lumia 920 and HTC 8X." Every phone and every OS has its problems, and happy users probably aren't as vocal; it would be good to know how Windows Phone users who are also iOS and Android users compare them for reliability.

An anonymous reader writes "The state-by-state election outcome probabilities today on Nate Silver's 538 imply a 97.7% probability for Obama to win 270 or more electoral college votes this coming Tuesday. A site that allows anyone but U.S. citizens vote seems to indicate that the rest of the world hopes these numbers are accurate. "

mask.of.sanity writes "A security researcher has demonstrated a series of attacks that are capable of disabling touch tone and voice activated phone systems, forcing them to disclose sensitive information. The commands can be keyed in using touchtones or even using the human voice. In one test, a phone system run by an unnamed Indian bank had dumped customer PINs. In another, a buffer overflow was triggered against a back-end database. Other attacks can be used to crash phone systems outright."
