The supercomputer had a 5.2V power supply that delivered almost 800 amps to the circuitry. The machine was the size of a small Volkswagen and required a refrigeration system to dissipate the 4000 watts of electricity it took to run.
The fastest PC video card on the market today costs $1000 and can execute floating point math at 8,200,000 MFLOP, consumes energy at a rate of just less than 400 watts, and is about the size of a paperback book.
50,000 times faster, 1/36,000 the price, 1/10th the energy, and about 1/5,000 the volume. It's interesting how they had to solve the enormous power requirements of supercomputers at the time, and how they have continued to solve them over the years as power densities have increased.

Neanderthals split from the primate line that gave rise to modern humans about 400,000 years ago. This group then moved to Eurasia and completely disappeared from the world about 30,000 years back. Other studies have shown that Neanderthals might have lived near the Arctic Circle around 31,000 to 34,000 years ago."

One might thing the EFF would have a good system for vetting potential donors for possible conflicts of interest, but apparently missed the fact that Mark Cuban, who reportedly owns a 7.4% stake in patent troll Vringo, is currently embroiled in several patent trolling lawsuits against the likes of Google and Target.
"In March, Vringo merged with Innovate/Protect, which is basically a patent troll. It ended up owning search-monetization patents from Lycos. It's using those patents in lawsuits with Google, AOL, Gannett, Target and IAC, according to a Vringo press release.
Suing Google over years-old patents that aren't being used is absurd. But that might be the appeal to Cuban.""

I saw that the content loaded before a black cover page was added, making it obvious they were just using a script to cover the content after it loaded. So, I enabled NoScript for Wikipedia and voila! I can now see English Wikipedia during the blackout."

This would obviate the need to carry around a bunch of paper, and could even be used to store e-textbooks so she doesn't have to lug 30lbs of books around campus.
At minimum, she would have to be able to write freehand on the tablet with a fine-point stylus, just like she would write on paper with a pen. We've seen what we call those "fat finger" styli and found that they are not good for fine writing.
Having become frustrated with the offerings we've tried so far, I thought I would ping the Slashdot Community. Any suggestions?"

The unauthorized surveillance started in June 2010, when the latest version of Apple's mobile operating system was released, according to two researchers who say they discovered a hidden tracking file and posted it out of concern for users.

This doesn't violate your Fourth Amendment rights, because you do not have any reasonable expectation of privacy in your own driveway — and no reasonable expectation that the government isn't tracking your movements."
"The court went on to make a second terrible decision about privacy: that once a GPS device has been planted, the government is free to use it to track people without getting a warrant."
I guess if you can't afford to put gates and access control around your property, then you have fewer rights than those who can."
EmagGeek writes: "The current and most common paradigm for reviewing employee performance seems to be the standard annual review of accomplishments against the employee's goals and objectives for the review period. In my company, compensation is determined mostly by the outcome of the goal and objective review. However, titles and ranks (and therefore promotions and career advancement — or ending) are determined by a completely separate set of criteria, among them being engineering expertise. We do not currently have an established way to objectively measure employee proficiency, so I was curious if you've experienced being rated for your engineering proficiency, and if so, how was that accomplished, and also whether you have been promoted or demoted or received an adjustment in compensation as a result of it."
EmagGeek writes: "University researchers have created a transistor by replacing just seven atoms of silicon with phosphorous. The seven-atom transistor has very hopeful implications for the future of quantum cryptography, nuclear and weather modeling, and other applications.
"The significance of this achievement is that we are not just moving atoms around or looking at them through a microscope," says Professor Michelle Simmons, a co-author of a paper on the subject that is being published by Nature Nanotechnology. The paper is entitled "Spectroscopy of Few-Electron Single-Crystal Silicon Quantum Dots".
"We are manipulating individual atoms and placing them with atomic precision, in order to make a working electronic device," elaborated Simmons. "We have replaced just seven individual silicon atoms with phosphorus atoms. That is amazing exactness"."
EmagGeek writes: "SEATLLE (AP) — Apple today recalled all of its new iPad tablet computers after learning that it had been sold thousands of counterfeit components that could cause short circuits in the device. A spokesperson for Apple, speaking on condition of anonymity, said "we learned Monday that many of our iPad devices were failing factory test with short circuited capacitors. Upon further research, we discovered that we had received the components from an unauthorized vendor, and that those components were not genuine."
The spokesperson said there could be a delay in the delivery of iPads to many customers for several months while the recalled units are repaired, and that it was very important for all iPads to be returned for repair, because the components could explode if short circuited.
He would not say whether the recall would need to be extended to other Apple products, such as the popular iPod, iPhone, and iMac line of personal computers."

Electrodes and a control chip are inserted into a moth during its pupal stage. When the moth emerges the electrodes stimulate its muscles to control its flight.
This is creepy beyond all belief. I expect a run on bug lights any day."

BigDog is powered by a gasoline engine that drives a hydraulic actuation system. BigDog's legs are articulated like an animal's, and have compliant elements that absorb shock and recycle energy from one step to the next. BigDog is the size of a large dog or small mule, measuring 1 meter long, 0.7 meters tall and 75 kg weight.
This thing looks truly amazing. I can think of a number of uses for a robot such as this, including search and rescue, hostile package delivery, and more. Let the SkyNet tags fly!"
