Google Caffeine Drops MapReduce, Adds "Colossus" 65

Posted by samzenpus from the time-to-upgrade dept.
An anonymous reader writes "With its new Caffeine search indexing system, Google has moved away from its MapReduce distributed number crunching platform in favor of a setup that mirrors database programming. The index is stored in Google's BigTable distributed database, and Caffeine allows for incremental changes to the database itself. The system also uses an update to the Google File System codenamed 'Colossus.'"

Toyota Develops New Flower Species To Reduce Pollution 211

Posted by timothy from the better-than-to-cause-it dept.
teko_teko writes "Toyota has created two flower species that absorb nitrogen oxides and take heat out of the atmosphere. The flowers, derivatives of the cherry sage plant and the gardenia, were specially developed for the grounds of Toyota's Prius plant in Toyota City, Japan. The sage derivative's leaves have unique characteristics that absorb harmful gases, while the gardenia's leaves create water vapour in the air, reducing the surface temperature of the factory surrounds and, therefore, reducing the energy needed for cooling, in turn producing less carbon dioxide."

Legal War For WA State Sunshine Law 1364

Posted by kdawson from the public-acts-public-records dept.
joeszilagyi writes "In a major battle in Washington State, anti-gay rights groups created and got R-71 on the 2009 election ballot. This is a public initiative to put same-sex civil unions up for public vote. The real legal war then erupted: activists created WhoSigned.org to take advantage of WA state's Public Records Act, and put the names of all people who publicly endorsed R-71 on a public, SEO-optimized website. Lawsuits quickly followed, and today it reached the United States Supreme Court, in a matter of months. The records appear to have always been public, but have only been available in digital form since 2006. An assault on civil rights, an assault on marriage, or an assault on sunshine laws and freedom of information?"

For more fiction, how about The Curious Incident of the Dog in the Night-Time by Mark Haddon, which Publisher's Weekly summarized as "Christopher Boone, the autistic 15-year-old narrator of this revelatory novel, relaxes by groaning and doing math problems in his head, eats red-but not yellow or brown-foods and screams when he is touched." It has math problems scattered throughout.

Apps That Officially Support Wine 354

Posted by kdawson from the insert-alcohol-related-line-here dept.
David Gerard writes "Wine (the Windows not-an-emulator for Unix) runs Windows applications more often than not. (Certainly more often than Vista does.) Dan Kegel on the wine-users mailing list/forum has started gathering apps that declare Wine a supported platform. And there's now a Wine Support Honor Roll page on the Wine wiki. We need more apps that work with Wine stating that they consider it a supported platform. If you write Win32 open source or shareware, please open yourself to the wider market!"

Battlestar Galactica's Last Days 799

Posted by CmdrTaco from the starbuck-freaks-me-out dept.
bowman9991 writes "If your country was invaded and occupied by a foreign power, would you blow yourself up to fight back? If someone pointed a gun at your head and threatened to pull the trigger if you refused to sign a document you knew would lead to a hundred deaths (and you signed!), would that make you ultimately responsible? Does superior technology give you the moral right to impose your will on a technologically inferior culture? You wouldn't expect a mainstream television show to tackle such philosophically loaded questions, certainly not a show based on cheesy science fiction from the '70s, but if you've watched Battlestar Galactica since it was re-imagined in 2003, there has been no escape. The final fourth season is nearly over, and when the final episode airs, television will never be the same again. SFFMedia illustrates how Battlestar Galactica exposes the moral dilemmas, outrages, and questionable believes of the present as effectively (but more entertainingly) than any documentary or news program. It's not hard to see parallels in the CIA and US military's use of interrogation techniques in Bush's War on Terror, the effects of labeling one race as 'the enemy,' the crackdown on free speech, or the use of suicide bombers in Iraq."

Comment Do what I did: take a summer off (Score 1) 386

Do what I did and take a summer off.

Actually, I did a co-op (for which I received somewhat useless credit from my university) which sent me to Europe and Africa to do some computer work. They were specifically looking for a single person to do this, and it wasn't a common opportunity in my experience, but I jumped at the chance.

The following summer, I took part of the summer off from my required courses. For some courses, our short summer semester was divided in two, and in the first 6 weeks I took an outstanding gen-ed course, and in the second 6 weeks I went on a study abroad trip to Italy and studied Italian and Renaissance art, neither of which I had studied before or had a prior interest in. We studied at an Italian University from Monday to Friday (sometimes Thursday) and traveled around on the weekends, and then the last week was spent traveling full time.

That was one of the most fulfilling experiences of my life, and the irrelevant-to-my-degree but relevant-to-my-travels courses served as a nice break from my beloved 1's and 0's and greatly enriched the experience.

In short, I highly recommend finding a way to study abroad, even if it delays your graduation briefly.

Accident Could Lead To Better Digital Cameras 120

Posted by ScuttleMonkey from the digital-chamagne dept.
Dave Bullock (eecue) writes "Scientists at UCLA have accidentally created a material that will some day give us better, faster, cheaper, more flexible digital cameras. I toured their lab and shot a photo essay for Wired. Personally I'm looking forward to a quantum-dot embedded camera sensor someday soon. 'Graduate student Hsiang-Yu Chen was working on a new formula for solar cells when something went wrong. Instead of creating electricity when hit with light, the conductivity of the material she was working with changed. "The original purpose [was] to make a solar cell more efficient," says Chen. "However, during the research we found the solar cell phenomenon [had] disappeared." Instead, the test material showed high gain photoconductivity, indicating potential use as a photo sensor.'"

Excluding Intelligent Design Principles From the Search For Alien Life 308

Posted by Soulskill from the irreducible-simplicity dept.
KIdPanda writes "Prompted by pictures of man-made structures in the Utah desert, a SETI astronomer explains the sometimes-ambiguous difference between seeing the hand of God, alien intelligence, or nature. 'In my photographs, Shostak's SETI-trained eye — standing in for a pattern-crunching computer program — searched for an unexpected increase in visual order (or, in thermodynamic terms, a decrease in entropy caused by the rebellion of life against universal decay). A road or a tended field is mathematically simpler than a mountainous jumble or naturally varied vegetation. ... But there's an obvious problem: nothing is simpler than a sweep of blue sky, or the inky blackness of space. If simplicity is the benchmark, space itself is evidence of design."

New Nanotech Fabric Never Gets Wet 231

Posted by timothy from the good-for-lining-lunchboxes dept.
holy_calamity writes "New Scientist reports on a simple coating for polyester that renders it unwettable — even after two months underwater it emerges dry to the touch. Water cannot attach to the new fabric thanks to nanostructured filaments and a structure that traps a constant air layer. One potential use is for low-drag swim wear."

Torvalds's Former Company Transmeta Acquired and Gone 150

Posted by kdawson from the here's-to-you-mister-robinson dept.
desmondhaynes sends along a posting from the TechWatch blog detailing the sale of Transmeta (most recently discussed here). Linus moved ten time-zones west, from Finland to Santa Clara, CA, to join Transmeta in March 1997, before this community existed. Here is our discussion of the announcement of the Crusoe processor from 2000. Our earliest discussion of Transmeta was the 13th Slashdot story. "Transmeta, once a sparkling startup that set out to beat Intel and AMD in mobile computing, announced that it will be acquired by Novafora. The company's most famous employee, Linux inventor Linus Torvalds, kept the buzz and rumor mill about the company throughout its stealth phase alive and guaranteed a flashy technology announcement in early 2000. Almost nine years later Transmeta's journey is over." Update: 11/21 16:25 GMT by KD : It's not the 13th Slashdot story, only the 13th currently in the database. We lost the first 4 months at one point.

New Generator Boosts Wind Turbine Efficiency 50% 315

Posted by kdawson from the reap-the-whirlwind dept.
MagnetDroid writes "A startup company based in Vancouver has developed a new kind of generator that could harvest much more energy from the wind. The design could not only lower the cost of wind turbines but increase their power output by 50 percent to as much as 100 percent, in some locations. Normally, when wind speeds drop, a turbine's engine becomes less efficient. The new engine, from ExRo Technologies, runs efficiently over a wider range of conditions. The design replaces a mechanical transmission with what amounts to an electronic one. Magnets attached to a rotating shaft create a current, but individual coils can be turned on and off electronically at different wind speeds." The company will begin field-testing a small, 5KW wind turbine by early next year.

Ender in Exile 507

Posted by samzenpus from the read-all-about-it dept.
stoolpigeon writes "Orson Scott Card's work Ender's Game began as a novelette, which he says he wrote as a means of leading up to the full story he had developed, Speaker for the Dead. Ender's Game was published as a full novel in 1985, and won the Hugo and Nebula awards (as did Speaker for the Dead in '86 and '87). I think it is safe to say that Ender's Game is ensconced in its position as a science fiction classic. Now, 23 years later, Card has finished the first direct sequel to Ender's Game in his new novel Ender in Exile." Keep reading for the rest of JR's review.

Pinpointing Creativity In the Brain 85

Posted by Soulskill from the brain-and-brain-what-is-brain dept.
The Times Online has a lengthy story about the work being done to solve mysteries regarding the brain and various aspects of neuroscience. They discuss some of the "brain-training" myths and look at the quest to determine when and where creative thought originates. Quoting: "In fact, the whole process seems to be centred on one small part of the brain: the anterior superior temporal gyrus. This seems to be the point at which bits of information stored far apart in the brain are brought together. This may be an important clue as to how the brain organises itself. But it's only the beginning. At Goldsmiths College in London, Dr Joydeep Bhattacharya says the real issue is not the 'Aha!' moment itself, but the way it is produced in the brain and how we recognise it. 'We need to know the brain processes involved, to find how this moment is strong enough to reach consciousness. We know insight does not come from the sky.' This is the problem with all neuroscience. We don't really know what we are seeing."
