Pen Still Mightier Than the Laptop For Notetaking? 569

theodp writes "While waiting to see if the iPad is a game-changer, this CS student continues to take class notes with pen and paper while her fellow students embrace netbooks and notebooks. Why? In addition to finding the act of writing helps cement the lecture material in her mind, there's also the problem of keeping up with the professor: '[While taking notes on a laptop] every five minutes I found myself cursing at not being able to copy the diagram on the board.' So, when it comes to education or business, do you take notes on a notepad/netbook, or stick with good old-fashioned handwriting? Got any tips for making the transition, or arguments for staying the course?"

Dying Man Shares Unseen Challenger Video 266

longacre writes "An amateur video of the 1986 Space Shuttle Challenger explosion has been made public for the first time. The Florida man who filmed it from his front yard on his new Betamax camcorder turned the tape over to an educational organization a week before he died this past December. The Space Exploration Archive has since published the video into the public domain in time for the 24th anniversary of the catastrophe. Despite being shot from about 70 miles from Cape Canaveral, the shuttle and the explosion can be seen quite clearly. It is unclear why he never shared the footage with NASA or the media. NASA officials say they were not aware of the video, but are interested in examining it now that it has been made available."

Seinfeld's Good Samaritan Law Now Reality? 735

e3m4n writes "The fictitious 'good samaritan' law from the final episode of Seinfeld (the one that landed them in jail for a year) appears to be headed toward reality for California residents after the house passed this bill. There are some differences, such as direct action is not required, but the concept of guilt by association for not doing the right thing is still on the face of the bill."

Hope For Fixing Longstanding Linux I/O Wait Bug 180

DaGoodBoy writes "There has been a long standing performance bug in Linux since 2.6.18 that has been responsible for lagging interactivity and poor system performance across all architectures. It has been notoriously difficult to qualify and isolate, but in the last few days someone has finally gotten a repeatable test case! Turns out the problem may not even be disk related, since the test case triggers the bug only by transferring data either between two processes or threads. The test results are very revealing. The developer ran regressions all the way back to version 2.6.15 that demonstrate this bug has more than doubled the time to run the test in 2.6.28. Many, many people working at improving the desktop performance of Linux will be very happy to see this bug die. I know that I, personally, will find a way to send the guy that found this test case his beverage of choice in thanks. Please spread the word and bring some attention to this issue so we can get it fixed!"

Monty Python Banks On the Long Tail Via YouTube 222

JTRipper writes "Monty Python seems to have done the right thing. Instead of issuing take down notices of their videos on YouTube, they are doing it better themselves with their own YouTube channel. They are putting all their clips (including snips from their movies) up in a decent resolution, with the only caveat being a link to buying the movies and TV episodes from Amazon."

Mars Rover Spirit Still Alive 185

Toren Altair writes with this excerpt from a story at The Space Fellowship: "NASA's Mars Exploration Rover Spirit communicated via the Mars Odyssey orbiter today right at the time when ground controllers had told it to, prompting shouts of 'She's talking!' among the rover team at NASA's Jet Propulsion Laboratory, Pasadena, Calif. 'This means Spirit has not gone into a fault condition and is still being controlled by sequences we send from the ground,' said John Callas of NASA's Jet Propulsion Laboratory, Pasadena, Calif., project manager for Spirit and its twin, Opportunity."

A Look At Google's Newest Data Center 75

miller60 writes "Google doesn't allow the public inside its secret data centers. But a recent groundbreaking event at the company's new South Carolina data center provided glimpses of the exterior of the facility, which shows a design that has evolved since Google's Oregon data center made front page news. A new feature: an open, lighted area resembling a parking deck (containers?). Still missing: moats filled with sharks with friggin' laser beams on their head."

3M Launches First Pocket Projector 187

An anonymous reader writes "Popsci.com has a writeup on 3M's new pocket projector, the 3M MPro 110, set to launch on September 30. 'In a dark room, it could project a big enough image to be the ultimate cheap-o home theater. The projector will sell for a mere $359. It doesn't have a speaker, so you'll have to get that separately. But really, how good could a microscopic speaker jammed into this thing sound, anyway?'"

LHC Success! 1007

Tomahawk writes "It worked! The LHC was turned on this morning and has been shown to have worked. Engineers cheered as the proton particles completed their first circuit of the underground ring which houses the Large Hadron Collider (LHC). (And we're all still alive, too!)" Here is a picture from the control room which I'm sure makes sense to someone that isn't me.

Language May Have Evolved Earlier Than Supposed 240

Science News reports on research suggesting that humans' language ability may have developed earlier than we thought. Scientists used CT scanning of H. heidelbergensis skulls, more than 530,000 years old, to reconstruct the structure of the ear canal of this Neanderthal ancestor. They found evidence that the ears of these early hominids would have had a sensitivity peak in the same 2-4 KHz range that the ears of modern humans do — the range in which most information is carried in language. Sensory systems are neurologically expensive, and it's unlikely that the body would invest the resources in maintaining such a system if it didn't serve a purpose. Quoting: "It may be time to rethink the stereotype of grunting, wordless Neanderthals. The prehistoric humans may have been quite chatty — at least if the ear canals of their ancestors are any indication. The findings suggest human speech may have originated earlier than some researchers contend. Anthropologists disagree about whether language sprang up rapidly around 50,000 years ago or emerged more gradually over a longer period of time..."

Drug Reverses Retardation In Mice 318

snydeq writes "Rapamycin, a medication doctors prescribe to transplant patients to prevent organ rejection, has been used to reverse learning disorders and mild retardation associated with TSC (tuberous sclerosis complex) in mice. Because the condition is linked to autism, scientists believe the drug may be used to treat learning disabilities and short-term memory deficits in all kinds of autism as well. The scientists chose rapamycin after they realized the drug regulates one of the same proteins that the TSC gene does, just in different parts of the body. 'What was surprising is that we could give rapamycin to adult mice and reverse their condition,' said neurobiologist Alcino Silva of the David Geffen School of Medicine at UCLA. 'We did not know ... that this drug would be equally effective for the learning disabilities as it is for tissue rejection.' Rapamycin treatment leveled the playing field between normal and TSC mice in as little as three days."

How Facebook Stores Billions of Photos 154

David Gobaud writes "Jason Sobel, the manager of infrastructure engineering at Facebook, gave an interesting presentation titled Needle in a Haystack: Efficient Storage of Billions of Photos at Stanford for the Stanford ACM. Jason explains how Facebook efficiently stores ~6.5 billion images, in 4 or 5 sizes each, totaling ~30 billion files, and a total of 540 TB and serving 475,000 images per second at peak. The presentation is now online here in the form of a Flowgram."

Beer Brewing Bender Completed 113

An anonymous reader writes "The Beer Brewing Bender Project is finally completed. This is a fan built, full sized Bender from Futurama featuring a 6502 CPU powered brain to make him speak triggered by a prop remote control straight out of the show. Inside his body is a beer fermenter used to brew up a batch of real Benderbrau beer!"
