Comment A video can't answer questions. (Score 4, Interesting) 110

It also isn't nearly as good as a real teacher at inspiring students, and when a student doesn't get it, a video can't think of an alternate way to explain the same issue, or find an analogy the student understands.

This hatred of teachers becomes a downward spiral. We hate them, so we won't raise their pay, so fewer good people are inclined to take up the job -- who needs the hatred and the low pay? -- and so the quality gets worse, and down it goes.

Khan Academy is great, but it's only assistive technology, not a substitute for the real thing.

The Ugly Underbelly of Coder Culture 715

snydeq writes "Today's developers are overwhelmingly young and male, and they're barring the door from a more diverse workforce, writes Fatal Exception's Neil McAllister. 'Software development isn't just failing to attract women. It's actively pushing them away. ... Put all the pieces together, and you're left with an impression of developers that's markedly different from the geeks and nerds they're made out to be in popular culture. On the contrary, developers harbor the same attitudes and engage in the same behaviors you see whenever a subculture is overwhelmingly dominated by young males. They've even coined a clever name for programmers who think and behave like fraternity pledges: brogrammers,' McAllister writes. 'Developers like to think of their culture as a meritocracy, where the very best developers naturally rise to the top. But as long as the industry tends to exclude more than half of the potential workforce, that's nothing but pure arrogance.'"

Can NASA Warm Cold Fusion? 556

TomOfAmalfi writes "Andrea Rossi says he can provide domestic energy sources (about 10 kW) based on his E-Cat system (a Low Energy Nuclear Reaction or Cold Fusion energy source) for between 100 and 150 US$/kW and begin shipping this year. Many people are skeptical about Rossi's claims because he has not explained how his 'reactors' work (apparently the reactors contain ingenious security devices to prevent reverse engineering), there is no theoretical basis to support his process, and no one has supplied independent measurements to support the specs on his black boxes. However, buried at the bottom of a NASA web page there is a comment about progress in 'cold fusion' research and a link to the slides used in a September 2011 presentation (PDF) which talks about LENR research. NASA has also released a video describing the great benefits we will get from NASA LENR research. Could Rossi be on to something?"

Global Warming 'Confirmed' By Independent Study 967

chrb writes "The Berkeley Earth Surface Temperature Project — an independent study of Earth's historical temperature record partly funded by climate skeptics, including the Koch brothers — has released preliminary results that show the same warming trend as previous research. Project leader and physics professor Richard Muller, of the University of California, has stated that he was 'surprised' at the close agreement, and it 'confirms that these studies were done carefully.' The study also found that warming in the temperature record was not caused by poor quality weather monitoring stations — thus rejecting a frequent claim of skeptics. Climate skeptic Stephen McIntyre has previously said 'anything that [Muller] does will be well done.'"

Sony Sued For PlayStation Network Data Breach 404

suraj.sun writes "Like clockwork, the first lawsuit resulting from the security breach of the personal data of more than 75 million Sony PlayStation Network customers has been filed. The suit was filed today on behalf of Kristopher Johns, 36, of Birmingham, Ala., in the US District Court for the Northern District of California. Johns accuses Sony of not taking 'reasonable care to protect, encrypt, and secure the private and sensitive data of its users.' He also believes Sony took too long to notify him and other customers that their personal information had been exposed. Because of that, the complaint alleges, Sony did not allow its customers 'to make an informed decision as to whether to change credit card numbers, close the exposed accounts, check their credit reports, or take other mitigating actions.'"

Submission + - Republicans Want To Keep Students Out Of Voting (washingtonpost.com) 2

siliconbits writes: New Hampshire's new Republican state House speaker is pretty clear about what he thinks of college kids and how they vote. They're "foolish," Speaker William O'Brien said in a recent speech to a tea party group.
"Voting as a liberal. That's what kids do," he added, his comments taped by a state Democratic Party staffer and posted on YouTube. Students lack "life experience," and "they just vote their feelings."

Playmate Photo From Apollo 12 Up For Auction 211

Kilrah_il writes "When the Apollo 12 crew left Earth for a trip to the Moon, they did not know that the ground crew hid a surprise in one of the command module lockers: a calendar photo of Playboy Playmate DeDe Lind. Now this card is offered for auction, after being kept in the personal collection of command module pilot Richard Gordon, who added the following memo: 'This is to certify that the accompanying 4.5" x 6.25" cue card did, indeed, accompany me on my trip to the moon in the Command Module Yankee Clipper aboard the historic Apollo 12 lunar landing mission. This cue card, which flew with me to the moon, has been in my sole possession and part of my personal space collection since my return from the moon in 1969 aboard America's second lunar landing mission, and it remains one of the all-time greatest Apollo era astronaut "Gotcha's!"' For those interested, the minimum bid is $1000." Warning, contains pixelated nudity.
