Simple Device Claimed To Boost Fuel Efficiency By Up To 20% 674

Ponca City, We love you writes "Temple University physics professor Rongjia Tao has developed a simple device that could dramatically improve fuel efficiency in automobiles by as much as 20 percent. The device, attached to the fuel line of a car's engine near the fuel injector, creates an electric field that thins fuel, reducing its viscosity so that smaller droplets are injected into the engine. Because combustion starts at the droplet surface, smaller droplets lead to cleaner and more efficient combustion. Six months of road testing in a diesel-powered Mercedes-Benz automobile showed an increase from 32 miles per gallon to 38 mpg, a 20 percent boost, and a 12-15 percent gain in city driving. 'We expect the device will have wide applications on all types of internal combustion engines, present ones and future ones,' Tao wrote in the study published in Energy & Fuels. 'This discovery promises to significantly improve fuel efficiency in all types of internal combustion engine powered vehicles and at the same time will have far-reaching effects in reducing pollution of our environment,' says Larry F. Lemanski, Senior Vice President for Research and Strategic Initiatives at Temple."
Supercomputing

Submission + - Where are all the cool cell processor hacks?

edarmoc writes: "I chose to file this "ask-slashdot" under the category "supercomputing" because essentially that is what the cell processor is capable of becoming. It has already been demonstrated that linux is capable of running on the PS3 [video]. That itself is pretty pretty cool, and IBM is doing their own fun stuff with the blade server. So from what I understand, the cell is designed such that the PS3, Blade server, and even a cellphone with a cell processor could all link and act as one "super" computer. I'm guessing that the cell cellphone is a few years away, but with linux already running on PS3s in the wild, why haven't I heard about more cool stuff being done with the cell processor?"

The PlayStation 3 Launches In the U.S. 578

Sony's next-gen console has officially launched in the states, complete with an NYC launch party, and a giant line in San Francisco. While many gamers went home happy, the night was not without incident. There was also some ugliness, with individuals being hired to stand in line, as was done in Japan earlier this week. Overall, though, the news is positive for the hundreds of gamers who waited through the night for their new console. "As midnight approached, the first person in line, New York native Angel Paredes, was escorted into the SonyStyle Store where he was handed the first North American PS3 by Hirai and Stringer. The console's box also included a personal autographed message from Hirai. Paredes, his voice hoarse from interviews and arms tired from repeatedly hoisting the console, was a good sport, standing still for the multitude of photographers and offering a few words for anyone who asked. The first three gamers in line were comped their PS3s. Once the media buzz died down, the rest of the attendees were ushered in to get what they had been waiting for all week. Though the consoles' next destinations were unknown — many are expected to be posted on eBay for a quick profit — the next destinations of the new PS3 owners was clear — go home and get some rest. " Any readers spend the night in lines, and want to share about it? Did you eBay the thing, or are you just taking a break from Resistance? Let us know how things went, and what the system is like.

Mozilla People Answer Firefox 2.0 Questions 55

Chris Beard was "point" on this interview, but got help writing his answers to your questions from other Mozilla and Firefox people. (Since this was sort of a "companion" interview to one we did just before it with MSIE dude Dean Hachamovitch, you might want to look at the two Q&A posts side by side and compare the way they answered.)

Charity Shuns Open Source Code 115

brown-eyed slug writes, "The BBC has an article explaining Christian Aid's decision to use Microsoft software in preference to Linux. It re-opens the classic debate about the total cost of ownership, highlighting the wider availability of Microsoft skills, as well as the beneficial pricing policy of the Seattle giant. From the article: '...one of the things that we find is that Microsoft is viewed as the big, bad organization — but they've actually got some good corporate social responsibility. If you're a charity or an educational institution, you pay pence in the pound for the license, compared to what a major bank might pay.'" While the Christian Aid spokesman makes some good points, he seems to miss totally the idea of open code — confusing code with data.

Slashdot Posting Bug Infuriates Haggard Admins 262

Last night we crossed over 16,777,216 comments in the database. The wise amongst you might note that this number is 2^24, or in MySQLese an unsigned mediumint. Unfortunately, like 5 years ago we changed our primary keys in the comment table to unsigned int (32 bits, or 4.1 billion) but neglected to change the index that handles parents. We're awesome! Fixing is a simple ALTER TABLE statement... but on a table that is 16 million rows long, our system will take 3+ hours to do it, during which time there can be no posting. So today, we're disabling threading and will enable it again later tonight. Sorry for the inconvenience. We shall flog ourselves appropriately. Update: 11/10 12:52 GMT by J : It's fixed.

Zune Profits Go To Record Label 155

genegeek writes, "The New York Times reports that Microsoft has a new deal with Universal to share profits from Zune player sales. David Geffen, the media omniboss, is quoted: 'Each of these devices is used to store unpaid-for material...' The new business rationale is that stolen music should be paid for by profit sharing of newly sold Zune music players. Does that mean if you are not stealing music, you should get a discount on the players? Universal expects a similar deal from Apple when their current contract expires." Reader Gallenod adds, "Microsoft appears willing to spend millions and defer any potential profitability of the Zune simply to weaken Apple's bargaining power with recording companies and set a precedent for hardware manufacturers paying music companies."

A 5-Year Deal With Microsoft To Dump Novell/SUSE 174

Nicholas Petreley writes, "Wake up little SUSE, wake up. No, that's not good enough. Wake up SUSE customers, wake up. Novell is jeopardizing the future of Linux for its own short-term rewards. If you want to see Linux flourish, let alone survive, after Novell's five year deal with Microsoft expires, I suggest we make an alternative five-year deal with Microsoft. In this case, our part of the deal is to spend the next five minutes, months, or years migrating away from every shred of Novell/SUSE software in our home, office, or enterprise."

Bar Performer Arrested For Copyright Violations 282

Edis Krad writes, "An elderly Japanese bar manager and performer has been arrested for playing copyrighted songs on his harmonica. From the article: 'Investigators accuse Toyoda of illegally performing 33 songs such as the Beatles' songs "Here, There and Everywhere" and "Yesterday," whose copyrights are managed by the Japanese Society for Rights of Authors, Composers and Publishers. He allegedly performed the songs on the harmonica with a female pianist at the bar he operated between August and September this year.' This is for all those kids who are learning chords on their guitars — be ready to pay fees for practicing 'Smoke On The Water.' This story seems to be legit, though it reads like an Onion piece. It's only being reported in the Mainichi Daily News via MSN.

Salt Lake City Plan May Turn Sewer Waste To Energy 90

tuxd00d writes "The question goes something like this: How many toilet flushes does it take to power a light bulb? There's really no answer, but Salt Lake City is exploring a pilot project that would convert sewer waste into energy to run a heating and cooling system in a downtown building, city water department official Jeff Niermeyer said."

Choosing Your Next Programming Job — Perl Or .NET? 426

Trebonius asks: "I have just received two job offers in the same day. The first was for a job coding in Perl on Linux/UNIX platforms, for a small but very cool company around 120 miles from where I live. They play Half-Life together in the off-hours and the people I've talked to there seem very happy with the job and work environment there. I'd be making smallish web systems, and I'd basically have total control over the projects on which I work. They offered me 20% more than I make now. The second offer I received is for a huge nationwide company opening an IT office a couple blocks from where I currently work. They're an all-Microsoft shop — VB, C#, .NET, SQL200*, etc. I'd be a very small cog in a very large machine. They offered me 66% more than I'm making now. Benefits are essentially identical between the companies, so that's not a big factor. I'll also give the Perl company a chance to make me another offer, but what should the threshold be? How do you folks balance the desire for a fun job with the need to pay off debt?"
