Cellulosic Biofuel Finally Ready For the Road 355

wdebruij writes "After years of research, promises, and plenty of discussion here, biofuel from inedible greens such as switchgrass — and even from corn cobs — may finally be getting economically viable. Two enzyme producers, Novozyme and Genencor, have both announced that they can now produce fuel at prices competitive with current corn and petrol-based methods. This is particularly good news in the wake of another report that food-based biofuels could cause hunger."

Verizon To Allow Skype Calling On Its Network 98

The Verizon press release begins: "At the 2010 Mobile World Congress in Barcelona, Verizon Wireless and Skype today announced a strategic relationship that will bring Skype to Verizon Wireless smartphones in March." What used to be one of the most protective carriers anywhere has been opening up in major ways since the introduction of the Motorola Droid. Phandroid summarizes: "Starting next month, Verizon Smartphone users with data plans will enjoy free and unlimited Skype-to-Skype calls to anyone on the planet. And you’ll enjoy amazingly cheap Skype International calls as well. All this from Verizon Wireless’ 3G network." Some are wondering how the DoJ and law enforcement will react to a major upsurge in fully encrypted traffic.

Robots To Clear the Baltic Seafloor of WW-II Mines 286

An anonymous reader writes "A Russian company is building a massive natural gas pipeline that will run across the Baltic Sea floor. But first, they must clear some of the 150,000 unexploded bombs sitting at the bottom of the sea, left there by the Russian and German armies in the 1940s. About 70 of these mines, each filled with 300 kg of explosive charge, sit in the pipeline's path, mostly in its northern section just south of Finland. And so the company contracted to remove the mines is bringing in robots to do the dirty work. Here's how it will work: A research ship deploys the robot to the seabed, where it identifies the exact location of the explosive. After sounding a warning to surrounding ship traffic, scaring fish away using a small explosive, and then emitting a 'seal screamer' of high intensity noises designed to make the area around the blast quite uncomfortable for marine mammals, Bactec's engineers erupt a 5 kg blast, forcing the mine to detonate. This process ensures the safety of humans plus any animals living in the surrounding environment. The operation concludes with the robot being redeployed to clear up the scrap of the now-destroyed bomb."

Measuring the Speed of Light With Valentine's Day Chocolate Screenshot-sm 126

Cytotoxic writes "What to do with all of those leftover Valentine's Day chocolates? — a common problem for the Slashdot crowd. The folks over at Wired magazine have an answer for you in a nice article showing how to measure the speed of light with a microwave and some chocolate. A simple yet surprisingly accurate method that can be used to introduce the scientific method to children and others in need of a scientific education."

Malicious Spam Jumps To 3B Messages Per Day 211

Trailrunner7 writes "Last year saw a monstrous increase in the volume of malicious spam, according to a new report (PDF). In the second half of 2009, the number of spam messages sent per day skyrocketed from 600 million to three billion, according to new research. For some time now, spam has been accounting for 90 or more percent of all email messages. But the volume of spam had been relatively steady in the last couple of years. Now, the emergence of several large-scale botnets, including Zeus and Koobface, has led to an enormous spike in the volume of spam."

A Simple Guide To Net Neutrality 154

superapecommando writes in with a neutral introduction to net neutrality from ComputerWorld UK. While it doesn't go into a lot of technical depth, it's rare to see anything written on the subject that isn't rabid on one side or the other. "Google's recently announced plan to set up trial fiber-optic networks in the US with ultra-high-speed Internet connections puts the long running national debate over Net Neutrality back into high gear. A hot topic of discussion and debate in government and telecom circles since at least 2003, Net Neutrality, actually involves a broad array of topics, technologies and players. Here's a primer for those looking to get up to speed fast."

Aussie Attorney General Says Gamers Are Scarier Than Biker Gangs 409

Sasayaki writes "South Australian Attorney-General Michael Atkinson claims, in an interview with Good Game, that gamers were more of a threat to his family than biker gangs. This is the man who has been the biggest opponent to Australia receiving an R18+ rating for video games and who has the power to veto any such law introducing it."

A History of Media Technology Scares 119

jamesswift writes "Vaughan Bell at Slate has written an interesting article on the centuries old phenomenon of hysterical suspicion surrounding new media and the technologies that enable them. 'A respected Swiss scientist, Conrad Gessner, might have been the first to raise the alarm about the effects of information overload. In a landmark book, he described how the modern world overwhelmed people with data and that this overabundance was both "confusing and harmful" to the mind. The media now echo his concerns with reports on the unprecedented risks of living in an "always on" digital environment. It's worth noting that Gessner, for his part, never once used e-mail and was completely ignorant about computers. That's not because he was a technophobe but because he died in 1565.' The best line comes near then end: 'The writer Douglas Adams observed how technology that existed when we were born seems normal, anything that is developed before we turn 35 is exciting, and whatever comes after that is treated with suspicion.'"

Apple Bans Jailbreakers From the App Store 507

Hugh Pickens writes "Adam Mills writes in the Examiner that Apple has been cutting off access to the iTunes App Store for iPhone hackers and jailbreakers. Sherif Hashim, the iPhone developer who successfully hacked the iPhone OS 3.1.3 and unlocked the 05.12.01 baseband for iPhone 3GS and 3G devices, discovered he'd been cut off and twittered: '"Your Apple ID was banned for security reasons," that's what i get when i try to go to the app store, they must be really angry.' Another hacker, iH8Sn0w, who is behind the Sn0wbreeze tool, confirms that his account has also been deactivated even though iH8sn0w's exploit had only been revealed to Dev Team, the group responsible for the PwnageTool. 'It is kind of surprising that two people associated with jailbreaking have had this happen to them so soon after one another, but it's too early to say if this is a campaign that Apple is starting up,' writes Mills."

64-Bit Flash Player For Linux Finally In Alpha 172

Luchio writes "Finally, a little bit of respect from Adobe with this alpha release of the Adobe Flash Player 10 that was made available for all Linux 64-bit enthusiasts! As noted, 'this is a prerelease version,' so handle with care. Just remove any existing Flash player and extract the new .so file in /usr/lib/mozilla/plugins (or /usr/lib/opera/plugins)."

Did We Lose the Privacy War? 521

eihab writes "I've been a fanatic about my online privacy for the last few years. I've been using NoScript and blocking Google Analytics, disabling third-party cookies, encrypting IM and doing everything in my power to keep data-miners at bay. Recently, I've been feeling like I'm just doing too much and still losing! No matter what I do, I know that there's a weak link somewhere, be it my ISP, Flash cookies, etc. I've recently gotten AT&T U-Verse, who, according to their privacy statement, will be monitoring my TV watching habits for advertisement purposes. I'm extremely annoyed by that, yet I love the service so much and I don't think I can cancel it. I just can't take this anymore. I have nothing to hide, but I do not want to be profiled and become member #5534289 in a database somewhere that records everything I do. I know I'm not that interesting to anyone, but the idea of someone being able to pull up everything about me with a simple SQL SELECT statement and a couple of JOINS makes me cringe. One of the reasons I hate data mining is that data security is not understood and almost non-existent at a lot of places. Case in point: I changed my life insurance two years ago, and the medical firm that conducted my health screening was broken into and computers with non-encrypted hard drives and patients' data were stolen. That medical firm didn't really need my SSN, but then again neither did AT&T when I signed up for U-Verse. Am I just too paranoid? Is privacy dead? Should I just give up and accept the fact that privacy is not the norm anymore (like Facebook's founder recently said) or should I keep fighting the good fight for my privacy?"

Quality Concerns For Kingston microSD Cards 149

Andrew "bunnie" Huang, whom we've discussed before for his book on Xbox hacking and development of the Chumby, has made an interesting blog post about problems he's found with Kingston microSD cards. He first encountered a batch of bad cards during production of the ChumbyOne, and found Kingston initially unhelpful when trying to get them replaced. After noticing some unusual markings on the chips, he decided to investigate for himself, comparing the ID data and dissolving the cards' casings with nitric acid to take a look inside. He found that each of his Kingston-branded samples actually had a Toshiba/SanDisk memory chip inside, and that the batch of low-quality cards he received may not be as uncommon as he thought. "Significantly, Kingston is revealed as simply a vendor that re-marks other people's chips in its own packaging. Every Kingston card surprisingly had a SanDisk/Toshiba memory chip inside, and the only variance or 'value add' that could be found is in the selection of the controller chip. ... This tells me that Kingston must be crushed when it comes to margin, which may explain why irregular cards are finding their way into their supply chain. Kingston is also probably more willing to talk to smaller accounts like me because as a channel brand they can't compete against OEMs like Sandisk or Samsung for the biggest contracts from the likes of Nokia or RIMM. Effectively, Kingston is just a channel trader and is probably seen by SanDisk/Toshiba as a demand buffer for their production output. I also wouldn't be surprised if SanDisk/Toshiba was selling Kingston 'A-' grade parts, i.e., parts with slightly more defective sectors, but otherwise perfectly serviceable. As a result, Kingston plays a significant and important role in stabilizing microSD card prices and improving fab margins, but at some risk to their own brand image."

Meteorite Contains Complex Organic Molecules 106

An anonymous reader writes "Previously unknown organic molecules have been discovered in a 100 kg meteorite that hit Australia in 1969, suggesting that our early Solar System contained a soup of highly complex organic chemistry long before life appeared. Quoting: 'According to [the study's lead author], the newly discovered compounds in the Murchison meteorite "may have contributed to the organic complexity of the early 'soup' that led to the development of life on Earth." The findings also suggest that extraterrestrial chemical diversity surpasses that found on Earth. The meteor probably passed through primordial clouds in the early solar system, accumulating organic molecules in a snowball effect along the way. By tracing the sequence of organic molecules in the meteorite, researchers believe they may also be able to create a timeline for their formation and alteration since the early days of our solar system.'"

"Green" Ice Resurfacing Machines Fail In Vancouver 356

lurking_giant writes "The Seattle Times is reporting that the Men's 500 meter speed-skating competition was delayed more than an hour Monday evening by the breakdown of the two ice grooming machines at the skating oval. The real story is that the machines that failed were the latest state-of-the-art 'Resurfice Fume-Free Electric Groomers' leased to the Olympics committee. An old, propane-powered Zamboni had to be brought out to fix the ice. This makes two nights in a row with ice resurfacing machine failures. If you're going to spend twice as much on electric devices to replace non-green designs, at least test the things first."
