$1/Gallon "Green Gasoline" In Sight 740

mattnyc99 writes "We've gotten excited here about the startup that claims it can make $1/gallon ethanol out of anything from trash to tires. But we've also seen how cellulosic ethanol is a better option, and how ethanol demand in general is only adding to the worldwide food crisis. So what about $1/gallon gasoline? NSF-funded researchers at UMass Amherst just completed the first direct conversion from cellulose using a new method of hydrocarbon refining, which they claim can be commercialized within 5-10 years and essentially make fuel out of anything that grows. Quoting: 'We already have the infrastructure in place to distribute liquid fuels. We're using them to power transportation vehicles today, and I think that's what we'll be using in 10 years and in 50 years,' Huber says. 'And if you want a sustainable liquid transportation fuel, biomass is the only way to go.'" The process is running at about 50% efficiency now; the $1/gallon figure is based on getting to 100%.

Windows Vista SP1 Meeting Sour Reception In Places 501

Stony Stevenson writes "A day after it was released for public download, Windows Vista SP1 is drawing barbs from some computer users who say the software wrecked their systems. 'I downloaded it via Windows Update, and got a bluescreen on the third part of the update,' wrote 'Iggy33' in a comment posted Wednesday on Microsoft's Vista team blog. Iggy33 was just one of dozens of posters complaining about Vista Service Pack 1's effect on their PCs. Other troubles reported by Vista SP1 users ranged from a simple inability to download the software from Microsoft's Windows Update site to sudden spikes in memory usage. To top it all off, the service pack will not install on computers that use peripheral device drivers that Microsoft has deemed incompatible."

Nerve-tapping Neckband Allows 'Telepathic' Chat 205

ZonkerWilliam writes "Newscientist has an interesting article on tapping the nerve impulses going from the brain to the vocal chords, allowing for 'Voiceless' phone calls. "With careful training a person can send nerve signals to their vocal cords without making a sound. These signals are picked up by the neckband and relayed wirelessly to a computer that converts them into words spoken by a computerized voice." It's not quite telepathy, but it's pretty close."

Netgear Introduces Linux-Based NAS Devices 128

drewmoney writes "A LinuxDevices.com article introduces several of Netgear's Linux-based NAS devices, technology they acquired with the purchase of Infrant earlier this year. (Here is Netgear's product page.) There are models from 1.5 TB, at about $1,100, to 4 TB, topped by a 4-TB rack-mount version. They are geared towards the professional home user and small and medium businesses. The NAS devices come complete with the usual RAID features, file-system access, and a built in USB print server. All are controlled through a Web GUI and some even offer SSH access."

Guantanamo Officers Caught Modifying Wikipedia 598

James Hardine writes "Wikileaks reports that US armed forces personnel at Guantanamo have conducted propaganda attacks over the Internet. (The story has been picked up by the NYTimes, The Inquirer, the New York Daily News, and the AP.) The activities documented by Wikileaks include deleting Guantanamo detainees' ID numbers from Wikipedia, posting of self-praising comments on news websites in response to negative articles, promoting pro-Guantanamo stories on the Internet news focus website Digg, and even altering Wikipedia's entry on Cuban President Fidel Castro to describe him as 'an admitted transsexual' (misspelling the word 'transsexual'). Guantanamo spokesman Lt. Col. Bush blasted Wikileaks for identifying one 'mass communications officer' by name, who has since received death threats for 'simply doing his job — posting positive comments on the Internet about Gitmo.'"

Fake E-Mail Results in Angry Apple Shareholders 193

drhamad writes "Apple stock dropped 2.2% today in mid-afternoon trading as Engadget published news based on a faked e-mail inside Apple. 'Apparently an internal memo was sent to several Apple employees--and forwarded to Engadget--around 9am CT today saying that Apple issued a press release with the news that the iPhone was now scheduled for October, and Leopard was delayed until January. About an hour and a half after that e-mail went out, a second e-mail was sent--this time officially from Apple--saying the first e-mail was a fake, and that the delivery schedule for the iPhone and Leopard had not changed.'"

Own Your Own 128-Bit Integer 477

Byte Swapper writes "After all the fuss over the AACS trying to censor a certain 128-bit number that now has something over two million hits on Google, the folks at Freedom to Tinker would like to point out that you too can own your own integer. They've set up a script that will generate a random number, encrypt a copyrighted haiku with it, and then deed the number back to you. You won't get a copyright on the number or the haiku, but your number has become an illegal circumvention device under the DMCA, such that anyone subject to US law caught distributing it can be punished under the DMCA's anti-trafficking section, for which the DMCA's Safe Harbor provisions do not apply. So F9090211749D5BE341D8C5565663C088 is truly mine now, and you can pry it out of my cold, dead fingers!"

EFF and Dvorak Blame the Digg Revolt On Lawyers 262

enharmonix writes "A bit of an update on the recent Digg revolt over AACS. The NYTimes has taken notice and written quite a decent article that actually acknowledges that the take-down notices amount to censorship and documents instances of the infamous key appearing in purely expressive form. I was pleased to see the similarity to 2600 and deCSS was not lost on the Times either. More interesting is that the EFF's Fred von Lohmann blames the digg revolt on lawyers. And in an opinion piece, John Dvorak expands on that theme."

Digg.com Attempts To Suppress HD-DVD Revolt 1142

fieryprophet writes "An astonishing number of stories related to HD-DVD encryption keys have gone missing in action from digg.com, in many cases along with the account of the diggers who submitted them. Diggers are in open revolt against the moderators and are retaliating in clever and inventive ways. At one point, the entire front page comprised only stories that in one way or another were related to the hex number. Digg users quickly pointed to the HD DVD sponsorship of Diggnation, the Digg podcast show. Search digg for HD-DVD song lyrics, coffee mugs, shirts, and more for a small taste of the rebellion." Search Google for a broader picture; at this writing, about 283,000 pages contain the number with hyphens, and just under 10,000 without hyphens. There's a song. Several domain names including variations of the number have been reserved. Update: 05/02 05:44 GMT by J : New blog post from Kevin Rose of Digg to its users: "We hear you."

Supreme Court Sides With Microsoft Over AT&T 122

The Supreme Court today sided with Microsoft in another important patent case filed by AT&T. The case centered around whether selling Windows overseas infringed on AT&T's patents that are in Windows. Microsoft argued [PDF] that the copies being sold in Asia were "...not technically supplied from the United States because overseas manufacturers of its computers made copies of the software from a master disk and installed those copies into the operating system. Microsoft said it could not be considered a supplier since the copies, not the original software, were in the computers built abroad." Now, while I support the weakening of software patents in general, by this logic, would that mean that MS's patents don't apply to those that use pirated copies of Windows?

RIAA Announces New Campus Lawsuit Strategy 299

An anonymous reader writes "The RIAA is once again revising their lawsuit strategy, and will now be sending college students and others "pre-lawsuit letters." People will now be able to settle for a discount. How nice."

67-Kilowatt Laser Unveiled 395

s31523 writes "Lawrence Livermore National Laboratory in California has announced they have working in the lab a Solid State Heat Capacity Laser that averages 67 kW. It is being developed for the military. The chief scientist Dr. Yamamoto is quoted: 'I know of no other solid state laser that has achieved 67 kW of average output power.' Although many lasers have peaked at higher capacities, getting the average sustained power to remain high is the tricky part. The article says that hitting the 100-kW level, at which point it would become interesting as a battlefield weapon, could be less than a year away."

Submission + - Did D-Wave really demonstrate a quantum computer?

Qubert writes: Was D-Wave's quantum computer demo last week the real thing? Ars Technica takes a look inside the cold, black box and concludes that whatever was in there, it probably wasn't a 'pure' quantum computer: 'Jumping off the fence, we will say that we think D-Wave demonstrated a real device; however, we think their device is going to set off a debate in the physics community over where the boundary between classical and quantum computation is. At present, quantum computers are "globally phase coherent," which means that every qubit's state is entangled (and therefore correlated) with every other qubit... The D-wave system, however, is certainly not globally phase coherent, which raises the question of whether it is a quantum computer.'
