Inventor Demonstrates Infinitely Variable Transmission 609

Posted by Soulskill on Saturday May 15, 2010 @11:26AM from the clutch-discovery dept.

ElectricSteve writes with this excerpt from Gizmag: "Ready for a bit of a mental mechanical challenge? Try your hand at understanding how the D-Drive works. Steve Durnin's ingenious new gearbox design is infinitely variable — that is, with your motor running at a constant speed, the D-Drive transmission can smoothly transition from top gear all the way through neutral and into reverse. It doesn't need a clutch, it doesn't use any friction drive components, and the power is always transmitted through strong, reliable gear teeth. In fact, it's a potential revolution in transmission technology."

1 Molecule Computes Thousands of Times Faster Than a PC 246

alexhiggins732 writes with this tantalizing PopSci snippet: "A demo of a quantum calculation carried out by Japanese researchers has yielded some pretty mind-blowing results: a single molecule can perform a complex calculation thousands of times faster than a conventional computer. A proof-of-principle test run of a discrete Fourier transform — a common calculation using spectral analysis and data compression, among other things — performed with a single iodine molecule transpired very well, putting all the molecules in your PC to shame."

Open Source Developer Knighted 101

Posted by samzenpus on Sunday May 02, 2010 @06:02PM from the knights-who-say-free dept.

unixfan writes "Georg Greve, developer of Open Document Format and active FOSS developer, has received a knighthood in Germany for his work. From the article: 'Some weeks ago I received news that the embassy in Berne had unsuccessfully been trying to contact me under FSFE's old office address in Zurich. This was a bit odd and unexpected. So you can probably understand my surprise to be told by the embassy upon contacting them that on 18 December 2009 I had been awarded the Cross of Merit on ribbon (Verdienstkreuz am Bande) by the Federal Republic of Germany. As you might expect, my first reaction was one of disbelief. I was, in fact, rather shaken. You could also say shocked. Quick Wikipedia research revealed this to be part of the orders of knighthood, making this a Knight's Cross.'"

Confessions of a SysAdmin 385

Posted by Soulskill on Friday April 23, 2010 @05:30PM from the type-with-your-fists dept.

Mr.Fork writes "Scott Merrill from CrunchGear has a confession. He really, really hates computers. He writes: 'No, really, I hate them. I love the communications they facilitate, I love the conveniences they provide to my life, and I love the escapism they sometimes afford; but I actually hate the computers themselves. Computers are fragile, unintuitive things — a hodge-podge of brittle hardware and opaque, restrictive software.' Does his editorial speak to all of us in similar IT-related fields? Do we all silently hate the complexities and idiosyncrasies computers have, like error messages and UI designs that make no sense to the common user, which make our tech professions miserable?"

Adding Some Spice To *nix Shell Scripts 411

Posted by kdawson on Monday April 19, 2010 @07:14PM from the ten-little-endians dept.

An anonymous reader writes "Developing GUI script-based applications is time-consuming and expensive. Most Unix-based scripts run in a CLI mode or over a secure ssh session. The Unix shells are quite sophisticated programming languages in their own right: they are easy to design and quick to build, but they are not user-friendly in the same way the Unix commands aren't (see the Unix haters books). Both Unix and bash provide features for writing user friendly scripts using various tools to build powerful, interactive, user-friendly scripts that run under the bash shell on Linux or Unix. What tools do you use that spice up your scripts on the Linux or Unix platforms?"

Demo of Laptop/Tabletop Hybrid UI 66

Posted by CmdrTaco on Wednesday April 14, 2010 @10:11AM from the computer-is-watching dept.

TheGrapeApe writes "The ACM Symposium on User Interface Software and Technology (ACMUIST) has an interesting proof-of-concept video up demonstrating the use of cameras and laser pico-projectors to 'extend' a laptop's user interface to adjacent surfaces. The video demonstrates some simple gestures like tapping and dragging being captured on the 'extended' surface. While the prototype appears to be somewhat cumbersome, it's easy to see how it might be more elegantly integrated into the hardware with more R&D."

C Programming Language Back At Number 1 535

Posted by kdawson on Tuesday April 06, 2010 @11:13PM from the doin'-what-we-always-did dept.

derrida writes "After more than 4 years C is back at position number 1 in the TIOBE index. The scores for C have been pretty constant through the years, varying between the 15% and 20% market share for almost 10 years. So the main reason for C's number 1 position is not C's uprise, but the decline of its competitor Java. Java has a long-term downward trend. It is losing ground to other languages running on the JVM. An example of such a language is JavaFX, which is now approaching the top 20."

Court Says Parents Can Block PA "Sexting" Prosecutions 383

Posted by timothy on Thursday March 18, 2010 @02:02PM from the and-maybe-they-can dept.

mikesd81 writes "In the first federal appeals court opinion dealing with 'sexting,' a three-judge panel of the United States Court of Appeals for the Third Circuit ruled Wednesday that parents could block the prosecution of their children on child pornography charges for appearing in photographs found on some classmates' cellphones. Miller vs. Mitchell (PDF) began in 2008 when school officials in Tunkhannock, Pa., discovered seminude and nude photographs of some female students on other student's phones. George Skumanick Jr., the DA at the time, said the students and their parents could be prosecuted if they did not participate in an after-school 'education program.' The unanimous ruling of the judges, Thomas L. Ambro, Michael A. Chagares and Walter K. Stapleton, criticized the district attorney's reliance on the girls' presence in the photographs as a basis for the potential charges. 'Appearing in a photograph provides no evidence as to whether that person possessed or transmitted the photo,' said the opinion, by Judge Ambro."

Quantum State Created In Largest Object Yet 265

Posted by samzenpus on Thursday March 18, 2010 @01:18PM from the hoping-each-time-that-his-next-leap-will-be-the-leap-home. dept.

SpuriousLogic writes "A team of researchers have created a 'quantum state' in an object billions of times larger than ever before. From the article: 'Such states, in which an object is effectively in two places at once, have until now only been accomplished with single particles, atoms and molecules. In this experiment, published in the journal Nature, scientists produced a quantum state in an object billions of times larger than previous tests. The team says the result could have significant implications in quantum computing.'"

An anonymous reader writes "After seeing Opera's claim to 'Fastest Browser on Earth' after their most recent release, Tom's Hardware put Apple Safari 4.04, Google Chrome 4.0, Microsoft Internet Explorer 8, Mozilla Firefox 3.6, and Opera 10.50 through a gauntlet of speed tests and time trials to find out which Web browser is truly the fastest. How does your favorite land in the rankings?"

First Creation of Anti-Strange Hypernuclei 179

Posted by kdawson on Friday March 05, 2010 @12:44PM from the quark-gluon-plasma dept.

runagate writes "Brookhaven National Laboratory has created a heretofore unknown form of matter. The matter we normally encounter, and are composed of, has nuclei of protons and neutrons that contain no strange quarks. It was known that anti-strange matter could exist, and using the Solenoidal Tracker at Brookhaven's RHIC, scientists detected a couple of dozen instances of antihypernuclei. The 'Z' axis of the Periodic Table has already been extended in the positive direction by the discovery of hypernuclei, but this new discovery extends it in the negative direction for this new type of 'strange' antimatter — which may exist in the core of collapsed stars and may provide insight into why our universe appears to be made almost solely of matter and not antimatter." The Register's coverage reproduces a helpful diagram.

Have you ever heard of the Unix command dd? I think that may be what you want. It writes directly to a disk, regardless of filesystem and/or format.

Touchpad Meets Morphing Keyboard 85

Posted by ScuttleMonkey on Monday March 01, 2010 @12:11PM from the pure-awesome dept.

Several sources are reporting on the new offering from the British firm Pelikon which combines a touchpad and morphing keyboard into a unique little device. "This isn't just any old morphing keyboard, you see. Not only can the board be dynamically reconfigured by backlighting different portions of the keys — the entire surface of the thing doubles as a touchpad, which you can probably imagine has virtually limitless utility in a mobile device where the space for a true touchpad simply doesn't exist. Pelikon already works with Toshiba on its domestic-market Biblio, but we'd love to see it hit devices around the world — in fact, we wouldn't really mind if they just released this prototype they're showing as a Bluetooth accessory. diNovo Mini competitor, anyone?"

IBM Claims Breakthrough Energy-Efficient Algorithm 231

Posted by kdawson on Friday February 26, 2010 @09:52AM from the sensible-consistency dept.

jitendraharlalka sends news of a claimed algorithmic breakthrough by IBM, though from the scant technical detail provided it's hard to tell exactly how important the development might be. IBM apparently presented its results yesterday at the Society for Industrial and Applied Mathematics conference in Seattle. The breathless press release begins: "IBM Research today unveiled a breakthrough method based on a mathematical algorithm that reduces the computational complexity, costs, and energy usage for analyzing the quality of massive amounts of data by two orders of magnitude. This new method will greatly help enterprises extract and use the data more quickly and efficiently to develop more accurate and predictive models. In a record-breaking experiment, IBM researchers used the fourth most powerful supercomputer in the world... to validate nine terabytes of data... in less than 20 minutes, without compromising accuracy. Ordinarily, using the same system, this would take more than a day. Additionally, the process used just one percent of the energy that would typically be required."

New Method for Random Number Generation Developed 395

Posted by ScuttleMonkey on Monday February 22, 2010 @03:34PM from the lots-of-coin-flipping dept.

Science Daily is reporting that a German team has developed a new method of random number generation that they hope will improve security. "The German team has now developed a true random number generator that uses an extra layer of randomness by making a computer memory element, a flip-flop, twitch randomly between its two states 1 or 0. Immediately prior to the switch, the flip-flop is in a 'metastable state' where its behavior cannot be predicted. At the end of the metastable state, the contents of the memory are purely random. The researchers' experiments with an array of flip-flop units show that for small arrays the extra layer makes the random number almost twenty times more 'random' than conventional methods."
