An anonymous reader writes "Over on the PC World blog, Keir Thomas engages in some speculative thinking. Pretending to be writing from the year 2025, he describes a world of 'Good Enough computing,' wherein ultra-cheap PCs and notebooks (created to help end-users weather the 'Great Recession' of the early 21st century) are coupled to open source operating systems. This is possible because even the cheapest chips have all the power most people need nowadays. In what is effectively the present situation with netbooks writ large, he sees a future where Microsoft is priced out of the entire desktop operating system market and can't compete. It's a fun read that raises some interesting points."

Jon Larsson writes "Yesterday, the 33rd World Finals of the ACM International Collegiate Programming Contest were held at KTH — The Royal Institute of Technology in Stockholm, Sweden. World Champions, for the second consecutive year, are the Saint Petersburg State University of IT, Mechanics and Optics. They won in competition with 99 other teams from all six continents — the best of the over 7000 teams participating in the qualifying rounds during the past half year. The full results can be found here and the contest problem set is available here (PDF). For the first time ever, the whole event was broadcast live, both on the web and on national TV in Sweden. The broadcast was produced by media students of KTH and the Lillehammer University College in Norway. The webcast in its entirety (over 7 hours) can be viewed here."

Snowblindeye writes with this excerpt from the European Southern Observatory: "Well-known exoplanet researcher Michel Mayor today announced the discovery of the lightest exoplanet found so far. The planet, 'e,' in the famous system Gliese 581, is only about twice the mass of Earth. The team also refined the orbit of the planet Gliese 581 d, first discovered in 2007, placing it well within the habitable zone, where liquid water oceans could exist. Planet Gliese 581 e orbits its host star — located only 20.5 light-years away in the constellation Libra ('the Scales') — in just 3.15 days. 'With only 1.9 Earth-masses, it is the least massive exoplanet ever detected and is, very likely, a rocky planet,' says co-author Xavier Bonfils from Grenoble Observatory. Being so close to its host star, the planet is not in the habitable zone. But another planet in this system appears to be. ... The planet furthest out, Gliese 581 d, orbits its host star in 66.8 days. 'Gliese 581 d is probably too massive to be made only of rocky material, but we can speculate that it is an icy planet that has migrated closer to the star,' says team member Stephane Udry. The new observations have revealed that this planet is in the habitable zone, where liquid water could exist. '"d" could even be covered by a large and deep ocean — it is the first serious "water world" candidate,' continued Udry."

jd writes "The BBC is reporting that the United Nations' World Digital Library has gone online with an initial offering of 1,200 ancient manuscripts, parchments and documents. To no great surprise, Europe comes in first with 380 items. South America comes in second with 320, with a very distant third place being given to the Middle East at a paltry 157 texts. This is only the initial round, so the leader board can be expected to change. There are, for example, a lot of Sumerian and Babylonian tablets, many of which are already online elsewhere. Astonishingly, the collection is covered by numerous copyright laws, according to the legal page. Use of material from a given country is subject to whatever restrictions that country places, in addition to any local and international copyright laws. With some of the contributions being over 8,000 years old, this has to be the longest copyright extension ever offered. There is nothing on whether the original artists get royalties, however."

smolloy writes "The world's first X-ray laser (LCLS) has seen first light. A Free Electron Laser (FEL) is based on the light that is emitted by accelerated electrons when they are forced to move in a curved path. The beam then interacts with this emitted light in order to excite coherent emission (much like in a regular laser); thus producing a very short, extremely bright, bunch of coherent X-ray photons. The engineering expertise that went into this machine is phenomenal — 'This is the most difficult light source that has ever been turned on,' said LCLS Construction Project Director John Galayda. 'It's on the boundary between the impossible and possible, and within two hours of start-up these guys had it right on.' — and the benefits to the applied sciences from research using this light can be expected to be enormous: 'For some disciplines, this tool will be as important to the future as the microscope has been to the past,' said SLAC Director Persis Drell."

darkjohnson writes with this impressive excerpt from Rocketry Planet: "On April 25, 2009, history will be made. At Higgs Farm in Price, Maryland, Steve Eves will enter the history books as the person who flew the largest model rocket in history. The rocket will weigh over 1,600 pounds, it will stand over 36 feet tall and it will be powered by a massive array of nine motors: eight 13,000ns N-Class motors and a 77,000ns P-Class motor."

Kelson writes "The Wall Street Journal profiles Vincent Connare, designer of the web's most-hated font, Comic Sans. Not surprisingly, the font's origins go back to Microsoft Bob, where he saw a talking dog speaking in Times New Roman. Connare pulled out Watchmen and The Dark Knight Returns for reference, and created the comic book-style font over the next week. 'Mr. Connare has looked on, alternately amused and mortified, as Comic Sans has spread from a software project at Microsoft Corp. 15 years ago to grade-school fliers and holiday newsletters, Disney ads and Beanie Baby tags, business emails, street signs, Bibles, porn sites, gravestones and hospital posters about bowel cancer. ... The jolly typeface has spawned the Ban Comic Sans movement, nearly a decade old but stronger now than ever, thanks to the Web."

explosivejared writes "Forbes is running a story discussing the verdict in the Pirate Bay case and its implications on file sharing, specifically with regard to Google. The article points out what most people on Slashdot already realize: Google provides essentially the same service that the Pirate Bay does. The Pirate Bay case may be far from over, accounting for appeals, but the Pirate Bay's assumption of being unchallengeable was shattered. The article raises the question of whether or not Google is untouchable in the matter. The story is quick to point out how the situation resembles a futile game of cat-and-mouse, but given how the Pirate Bay's confidence was ultimately broken, is Google beyond reproach?"

GordonCopestake writes "An article from New Scientist proposes that all new spacecraft have sails attached to bring them back to earth — a measure that would reduce the amount of garbage in space. From the article: 'The risk to spacecraft from a collision with space debris could be reduced by equipping launchers with a gossamer-thin "sail." The idea is to deploy the sail after the rocket has released its payload to amplify the drag of the last vestiges of the atmosphere, and so force the rocket out of orbit.'" Wired has a related story about the risks faced by the space shuttles as they share orbits with tons of drifting space debris. "... in the 54 missions from STS-50 through STS-114, space junk and meteoroids hit shuttle windows 1,634 times necessitating 92 window replacements. In addition, the shuttle's radiator was hit 317 times, actually causing holes in the radiator's facesheet 53 times."

ApharmdB writes "Beneath a glacier in Antarctica, scientists have discovered a community of microbes growing in frigid pools of salty water. It's a particularly tough environment, with no light, no oxygen, and extremely cold temperatures. But the microbes appear to live — and thrive — off a combination of iron and sulfur, according to a new study. The result of that strange metabolism is a brilliant red streak of cascading ice called Blood Falls."

Ed Pegg writes "Theo Gray demonstrates the Bacon Lance, a flaming meatsword that can cut through steel. Yes, with some ordinary bacon, and some pure oxygen, it's possible to cut through security doors. Form the article, 'I recently committed myself to the goal, before the weekend was out, of creating a device entirely from bacon and using it to cut a steel pan in half. My initial attempts were failures, but I knew success was within reach when I was able to ignite and melt the pan using seven beef sticks and a cucumber.' This comes out right after his profusely illustrated book of science experiments, Mad Science."

TEDChris writes "The Allosphere, being created at UC Santa Barbara, is the most ambitious attempt yet at creating powerful 3d visualizations of raw scientific data, such as the structure of a crystal, or how quantum effects take place. Researchers watch from a bridge inside the 30-foot sphere, looking at data projected 360 degrees around them and listening to 3D sound. The first major public demo of the facility has just been posted at TED.com. Optimists would argue that many of the greatest scientific breakthroughs happened through a new visual way of imagining data. Penicillin and relativity come to mind. So this is either a killer new research vehicle, an incredible toy, or just an insanely expensive art project."

Alyssey writes "The Mexican government wants to have a database to track every cellphone number in the country (in Spanish, Google translation) and whom it belongs to. They want to tie in the CURP (Unique Registration Population Code in Spanish, like the Social Security Number in the US) with cellphone numbers. If Mexicans don't send in their number and CURP via SMS before April 10, 2010, their cellphone number will be blocked. The new law was published back in February and is going into effect now."

gabrlknght writes "Superstring theory claims the power to explain the universe, but critics say it can't be tested by experiment. Lately, though, string math has helped explain a couple of surprising experiments creating 'perfect liquids' at cosmic extremes of hot and cold. 'Both systems can be described as something like a shadow world sitting in a higher dimension. Strongly coupled particles are linked by ripples traveling through the extra dimension, says Steinberg, of Brookhaven. String math describing such ripples stems from an idea called the holographic principle, used by string theorists to describe certain kinds of black holes. A black hole's entropy depends on its surface area — as though all the information in its three-dimensional interior is stored on its two-dimensional surface. (The 'holographic' label is an allusion to ordinary holograms, where 3-D images are coated on a 2-D surface, like an emblem on a credit card.) The holographic principle has value because in some cases the math for a complex 3-D system (neglecting time) can be too hard to solve, but the equivalent 4-D math provides simpler equations to describe the same phenomena.'"
