gyrogeerloose writes "The San Diego Union-Tribune reports in a New York Times wire service story that a black bear known as 'Yellow-Yellow' (named for the two yellow ear tags she sports) has solved the problem of opening a food container that was previously thought to be bear-proof. The container, known as The Bear Vault, was constructed in a manner similar to a child-proof pill bottle, and had passed tests at zoos where bears were given a certain time to break in. The only bears able to open it were grizzlies large and strong enough to rip the lid off using brute force — up to several years ago, when campers in the High Peaks region of New York's Adirondack Mountains started reporting successful break-ins. A redesigned canister was introduced last year; Yellow-Yellow, a relatively petite 120-pound black bear, figured that one out too. The manufacturer is working on a new design expected to be released next year. New York state officials have agreed to test it by filling it with food and placing it in Yellow-Yellow's territory."

snydeq writes "Fatal Exception's Neil McAllister questions whether Scheme, a dialect of Lisp taught as part of many first-year CS curricula and considered by some to be the 'latin of programming,' is really the best first language for a young programmer. As he sees it, the essentially write-only Scheme requires you to bore down into the source code just to figure out what a Scheme program is trying to do — excellent for teaching programming but 'lousy for a 15-year-old trying to figure out how to make a computer do stuff on his own.' And though the 'hacker ethic' may in fact be harming today's developers, McAllister still suggests we encourage the young to 'develop the innate curiosity and love of programming that lies at the heart of any really brilliant programmer' by simply encouraging them to fool around with whatever produces the most gratifying results. After all, as Jeff Atwood puts it, 'what we do is craftmanship, not engineering,' and inventing effective software solutions takes insight, inspiration, deduction, and often a sprinkling of luck. 'If that means coding in Visual Basic, so be it. Scheme can come later.'"

High school teacher Frank McCourt had received dozens of excuse notes from students over the years, most of them forgeries. One day while looking at the pile of obvious fakes, and thinking about how much the kids complained about writing even short essays, he had an epiphany. Why not teach the art of the excuse note? "This is the first class to study the art of the excuse note — the first class, ever, to practice writing them. You're so lucky to have a teacher like me who has taken your best writing and turned it into a subject worthy of study," he said to the class. Frank's classes have written a wide range of notes including ones from Adam and Eve to god, and historical figures. Frank was even commended by the school superintendent for his innovative idea. "That kid writing an excuse note for Judas. Brilliant. I just want to shake your hand. There might be a letter in your file attesting to your energetic and imaginative teaching. Thank you," he said.

Reservoir Hill writes "The NY Times has an article investigating why, unlike the articles on Wikipedia which in theory are improved, fact checked, footnoted, and generally enhanced over time, the photos that go with Wikipedia articles are so bad and in many cases there is no photo at all for even well known public figures. Few high-quality photographs, particularly of celebrities, make it onto on Wikipedia because Wikipedia runs only pictures with the most permissive Creative Commons license, which allows anyone to use an image, for commercial purposes or not, as long as the photographer is credited. 'Representatives or publicists will contact us' horrified at the photographs on the site, says Jay Walsh, a spokesman for the Wikimedia Foundation. 'They will say: "I have this image. I want you to use this image." But it is not as simple as uploading a picture that is e-mailed to us.' Recent photographs on Wikipedia are almost exclusively the work of amateurs who don't mind giving away their work. 'Amateur may be too kind a word; their photos tend to be the work of fans who happen to have a camera,' opines the Times's author. Ultimately the issue for professional photographers who might want to donate their work is copyright. 'To me the problem is the Wikipedia rule of public use,' says Jerry Avenaim, a celebrity photographer. 'If they truly wanted to elevate the image on the site, they should allow photographers to maintain the copyright.'"

alphadogg writes "The recession appears to have finally caught up with the video game market. Sales of video game hardware and software were down by around one-third in June compared to the same month last year. After initially showing positive growth as the US slid into recession, the latest figures mark the fourth month of declines and the largest year-on-year decline in almost 9 years. 'The first half of the year has been tough largely due to comparisons against a stellar first half performance last year, but still, this level of decline is certainly going to cause some pain and reflection in the industry,' said Anita Frazier, a games analyst with NPD Group. She added, 'The size of the decline could also point to consumers deferring limited discretionary spending until a big event (must-have new title, hardware price cut) compels them to spend.' The entire video game market in the US was worth $1.2 billion in June, down 31 percent from the same period last year, according to NPD Group."

blackbearnh writes "The Human Genome Project took 13 years to sequence a single human's genetic information in full. At Washington University's Genome Center, they can now do one in a week. But when you're generating that much data, just keeping track of it can become a major challenge. David Dooling is in charge of managing the massive output of the Center's herd of gene sequencing machines, and making it available to researchers inside the Center and around the world. He'll be talking about his work at OSCON, and gave O'Reilly Radar a sense of where the state of the art in genome sequencing is heading. 'Now we can run these instruments. We can generate a lot of data. We can align it to the human reference. We can detect the variance. We can determine which variance exists in one genome versus another genome. Those variances that are cancerous, specific to the cancer genome, we can annotate those and say these are in genes. ... Now the difficulty is following up on all of those and figuring out what they mean for the cancer. ... We know that they exist in the cancer genome, but which ones are drivers and which ones are passengers? ... [F]inding which ones are actually causative is becoming more and more the challenge now.'"

Steve Henry and David Alberts have written a book, You Are Really Rich, You Just Don't Know It Yet, that tries to figure out the real world value of life's priceless moments. According to the authors, being told, "I love you" is worth £163,424, being in a stable relationship £154,849, and hanging out with your friends comes in at a measly £63,256. The values were determined by asking 1,000 people what made them happy and then comparing that event to the happiness they would feel after winning the lottery. "It was interesting when doing the research that very few people mentioned money and people focused on family occasion, hanging out with friends, having a quiet time on their own, seeing grandchildren and visiting places they had never seen before as things that made a real difference in their lives," said Alberts.

Linux and open source have long struggled to gain acceptance from the wider (read: non-technical) audience. This has improved in recent years, but still has a long way to go. Columnist Matt Asay suggests that perhaps open source projects should attempt to emulate Apple's design philosophy, with whoever succeeds becoming the "winner" of the hearts and minds of the vast majority of users. "Some projects already accomplish this to some extent. The strength of Mozilla, for example, is that it has figured out how to enable 40 percent of its development to be done by outside contributors, as BusinessWeek recently wrote. The downside is that these contributors are techies, but the upside is that they're techies who add language packs, accessibility features, and other "niche" areas that Mozilla might otherwise struggle to deliver. This suggests a start: enable your open-source project to accept meaningful outside contributions that make the project reflective of a wider development community. But the real goldmine is broadening the definition of "developer" to include lay users of your software. The day that I, as a nontechnical software user, can meaningfully participate in an open-source project is the day that open source will truly have won."

simoniker writes "As the latest in his Game Design Essentials series for Gamasutra, writer John Harris examines 10 games from the Western computer RPG (CRPG) tradition and 10 from the Japanese console RPG (JRPG) tradition, to figure out what exactly makes them tick. From the entry on Nethack: 'Gaining experience is supposed to carry the risk of harm and failure. Without that risk, gaining power becomes a foregone conclusion. It has reached the point where the mere act of spending time playing [most RPGs] appears to give players the right to have their characters become more powerful. The obstacles that provide experience become simply an arbitrary wall to scale before more power is granted; this, in a nutshell, is the type of play that has brought us grind, where the journey is simple and boring and the destination is something to be raced to. Nethack and many other roguelikes do feature experience gain, but it doesn't feel like grind. It doesn't because much of the time the player is gaining experience, he is in danger of sudden, catastrophic failure. When you're frequently a heartbeat away from death, it's difficult to become bored.' Harris' Game Design series has previously spanned subjects from mysterious games to open world games, unusual control schemes and difficult games."

BBC Magazine convinced 13-year-old Scott Campbell to trade in his iPod for a Walkman for a week and see what he thought. Scott thinks the iPod wins when it comes to sound quality, color, weight, and the shuffle feature. The Walkman, however, offers two headphone sockets, making it much easier to listen to music with a friend. My favorite part of the review is, "It took me three days to figure out that there was another side to the tape. That was not the only naive mistake that I made; I mistook the metal/normal switch on the Walkman for a genre-specific equalizer, but later I discovered that it was in fact used to switch between two different types of cassette."

Nancy Atkinson writes "Even though the Spirit rover is stuck in loose soil on Mars, she has an overabundance of electrical power due to a wind event that cleaned off her solar panels. While MER scientists and engineers are having the rover take pictures of her surroundings in an effort to figure a way to get her dislodged, there also is enough power (since the rover isn't moving anywhere) to do something extra: keep the rover 'awake' at night and run her heaters so she can take images of the night sky on Mars. 'Certainly, a month or more ago, no one was considering astronomy with the rovers,' said Mark Lemmon, planetary scientist at Texas A&M University and member of the rover team. 'We thought that was done. With the dust cleanings, though, everyone thinks it is better to use the new found energy on night time science than to just burn it with heaters.'"

Dusty writes "After several false alarms, the Ulysses Mission is finally ending. According to the Spacecraft Operations Manager's latest status report, the last track will be on 30th June 2009 from 15:25 until 20:20 UTC. 'We've tried to bolster our dwindling tracking allocation with some success by grabbing antenna time released on short notice (mostly by the Spitzer Project). However, weekly data return figures are now typically 10% or less. And soon, even 512 bps from 70m antennas will be a thing of the past.' Further details about Ulysses' 18-year mission are available from NASA and the ESA. We discussed the failing spacecraft last summer when it looked like its fuel was going to freeze, but through clever engineering, experts managed to squeeze out another year.

narramissic writes "In an interview on stage at GigaOm's Structure conference in San Francisco on Thursday, Jonathan Heiliger, Facebook's VP of technical operations, told Om Malik that the latest generations of server processors from Intel and AMD don't deliver the performance gains that 'they're touting in the press.' 'And we're, literally in real time right now, trying to figure out why that is,' Heiliger said. He also had some harsh words for server makers: 'You guys don't get it,' Heiliger said. 'To build servers for companies like Facebook, and Amazon, and other people who are operating fairly homogeneous applications, the servers have to be cheap, and they have to be super power-efficient.' Heiliger added that Google has done a great job designing and building its own servers for this kind of use."

Two six-year-old boys built a toy nuclear power plant complete with a radiation warning sign, and managed to freak out an entire German town. The boys left their creation on the street after they had to go home for dinner. A passer-by notified authorities, who cordoned off several streets, raised a public alert, and rushed a radiation detector to the scene to figure out how hot the empty computer case with a sign taped to it was. "It wasn't a prank, they were just playing," a local police spokeswoman said Tuesday. "The boys tried to go back later to carry on but the fire brigade wouldn't let them through."

The National Institutes of Health has given $423,500 to researchers at Indiana University's Kinsey Institute to figure out why men don't like to wear condoms. The institute will also study why men have trouble using condoms and investigate "penile erection and sensitivity during condom application." "The project aims to understand the relationship between condom application and loss of erections and decreased sensation, including the role of condom skills and performance anxiety, and to find new ways to improve condom use among those who experience such problems," reads the abstract from Drs. Erick Janssen and Stephanie Sanders, both of the Kinsey Institute.

skuzzlebutt writes "In a federal tax case reported in the Las Vegas Review Journal last week, a local businessman has been paying his employees in gold coins instead of cash or ACH, and has reportedly told them that they can only be taxed on the face value of the coinage — not the much higher market value of the metal. The United States disagreed, and brought him up on 57 counts of income tax evasion, tax fraud and criminal conspiracy. The non-authenticated comments section of the original article brought a lot of supporters out of the woodwork, including a few who thought the jury should be hung (literally, procedurally, or figuratively ... pick one). In response, the prosecution has subpoenaed the names of the anonymous commenters, citing fears of jury safety. Or something. The obvious questions of privacy and protected speech aside, for the folks that support the defendant (the newspaper is fighting the subpoena), this also brings back into the spotlight the troll-empowering nature of pseudo-anonymous, non-authenticated boards. If they want to find you, they will; is anonymous commenting still worth it, or is it just too risky for the board owners?"

RazvanM writes "This is an attempt to visualize the relationships among the Linux File Systems through the lens of the external symbols their kernel modules use. We took an initial look a few months back but this time the scope is much broader. This analysis was done on 1377 kernel modules from 2.6.0 to 2.6.29, but there is also a small dip into the BSD world. The most thorough analysis was done on Daniel Phillips's tree, which contains the latest two disk-based file systems for Linux: tux3 and btrfs. The main techniques used to establish relationships among file systems are hierarchical clustering and phylogenetic trees. Also presented are a set of rankings based on various properties related to the evolution of the external symbols from one release to another, and complete timelines of the kernel releases for Linux, FreeBSD, NetBSD, and OpenBSD. In all there are 78 figures and 10 animations."

pdragon04 writes "From the article, 'Through education Dr. Steven C. Schlozman is an assistant professor of psychiatry at Harvard Medical School and a lecturer at the Harvard School of Education. He is also an avid sci-fi and horror fan — and, apparently, the world's leading authority on the neurobiology of the living dead ... He conducted extensive research by talking with George Romero and immersing himself in genre literature and memorabilia — which is why the alternate title for his lecture is "A Way Cool Tax Deduction for a Bunch of Cool Books, Action Figures and a Movie."'"

18-year-old Jessica Terry suffered from stomach pain, diarrhea, vomiting and fever for eight years. She often missed school and her doctors were unable to figure out the cause of her sickness. Then one day in January someone was finally figured out what was wrong with Jessica. That person was her. While looking under a microscope at slides of her own intestinal tissue in her AP science class, Jessica noticed an area of inflamed tissue called a granuloma, which is an indication of Crohn's disease. "It's weird I had to solve my own medical problem," Terry told CNN affiliate KOMO in Seattle, Washington. "There were just no answers anywhere. ... I was always sick."
