An anonymous reader writes "On September 26th the Blender Foundation released their fourth open source short movie called Tears of Steel. This time around, Blender, the fantastic open source 3d modeling/animation/shading/rendering package, was used to mix 3D digital content with live action (PDF). The short was produced using only open source software and the team did an outstanding job."

sciencehabit writes "Like all invisible things that are only partly understood, black holes evoke a sense of mystery. Astronomers know that the tremendous gravitational pull of a black hole sucks matter in, and that the material falling in causes powerful jets of particles to shoot out of the hole at nearly the speed of light. But how exactly this phenomenon occurs remains a matter of conjecture, because astronomers have never quite managed to observe the details – until now. Astrophysicists have taken the closest look to date at the region where matter swirls around a black hole. By measuring the size of the base of a jet shooting out of the supermassive black hole at the center of the M87 galaxy (abstract), the researchers conclude that the black hole must be spinning and that the material orbiting must also be swirling in the same direction. Some of the material from this orbiting 'accretion disk' is also falling into the black hole, like water swirling down a drain."

mcpublic writes "For years the Computer History Museum has been quietly collecting and displaying the computational relics of yesteryear. Now, finally the New York Times Arts Section shines the spotlight on this most nerdy of museums. Speak Steampunk? You can find a working replica of Babbage's Difference Engine in the lobby of the museum's Mountain View, California home. Of course, the vast majority of the collection is electronic, and though 'big iron' is king, that hasn't stopped dedicated volunteers from bringing back to life pioneering 'mini' computers like the 1960 PDP-1 and the first video game software ever: Spacewar!"

Hugh Pickens writes "Will Oremus reports that Fox News showed a grisly spectacle Friday afternoon during a live car chase when the suspect got out of his car, stumbled down a hillside, pulled a gun, and shot himself in the head. As the scene unfolded, Fox News anchor Shepard Smith grew increasingly apprehensive, then yelled 'get off it, get off it!,' belatedly urging the show's producers to stop the live feed as it became obvious the man was going to do something rash. Fox News cut awkwardly to a commercial just after showing his death and after Fox aired the on-air suicide, Smith apologized to viewers, saying, 'We really messed up.' However BuzzFeed immediately posted the footage on YouTube, where it garnered more than 1,000 'likes' in under an hour, sparking immediate blowback. 'Who's worse? @FoxNews for airing the suicide, or @BuzzFeed for re-posting the video just in case you missed it the first time?' posted the Columbia Journalism Review. Gawker's Hamilton Nolan called his site's decision to post the video 'ethical,' because 'it is news' but research suggests that graphic depictions of suicide in the media can spur copycat suicides, especially among young people, and the World Health Organization's guidelines warn against sensationalizing it. Virtually everyone who has studied it agrees that, at a minimum, suicides should be covered with a modicum of sensitivity and context (PDF). 'Of course it's news that Fox News accidentally aired the video. And you can make a good case that Fox was inviting this type of debacle with its habit of airing live car-chase feeds. But Fox couldn't have known that it was about to air a suicide. BuzzFeed, by contrast, knew exactly what it was doing,' writes Oremus. 'That might be good business for BuzzFeed, but it's hard to see the benefit for anyone else.'"

b1tbkt writes "I live at the corner of one of the busiest intersections in my city (pop. 350k). Although I've replaced all windows, insulated, and caulked every square inch of the place, the fire trucks and cars with obnoxious stereos still regularly intrude on my home office. Most of the noise comes in through the windows. I'm considering mounting an oblong parabolic reflector in the ceiling above the windows with a steady feed of white or brownian noise directed into it (e.g., via a small speaker placed within the reflector) to create a 'wall' of sound that would act as a buffer to the outside world. Active noise cancellation would be nice, too, but that's probably more than I want to take on. I don't see any products on the market for this sort of thing. Does anyone have any experiences to share with similar homebrew noise remediation efforts?"

An anonymous reader writes "After just over a month of release candidates, the final version of Python 3.3 launched today. This version includes new syntax, including the yield from expression for generator delegation; new library modules, including fault handler (for debugging crashes), ipaddress, and lzma (for data compression using the XZ/LZMA algorithm); a reworked OS and I/O exception hierarchy; the venv module for programmatic access to Python virtual environments; and a host of API changes. The full list of features and the change log are both available."

An anonymous reader writes "Real-world military conventions have had obvious effects on many sci-fi books, movies, and TV shows. But how does their fictional representation stack up against the evolving rules of high-tech warfare? In an interview with Foreign Policy magazine, a naval analyst discusses some of the technological assumptions involved in transposing sea combat to space combat, and his amusement with the trope of 'aircraft carriers in space.' He says, 'Star Wars is probably the worst. There is no explanation for why X-Wings [fighters] do what they do, other than the source material is really Zeroes [Japanese fighter planes] from World War II. Lucas quite consciously copied World War II fighter combat. He basically has said they analyzed World War II movies and gun camera footage and recreated those shots. Battlestar Galactica has other issues. One thing I have never understood is why the humans didn't lose halfway through the first episode. If information moves at the speed of light, and one side has a tactically useful FTL [faster-than-light] drive to make very small jumps, then there is no reason why the Cylons couldn't jump close enough and go, "Oh, there the Colonials are three light minutes away, I can see where they are, but they won't see me for three minutes?"'"

An anonymous reader writes "Hewlett-Packard has announced the release Open webOS version 1.0: 'We now have an OpenEmbedded build that allows a full webOS experience running inside an OE emulator. We have added core applications — email & browser — while continuing to support the desktop build environment. The 1.0 release also brings support for Enyo2. You can now take apps built on one of the best cross-platform JavaScript frameworks and easily run these same apps on Open webOS or other platforms. In the past 9 months, we have delivered over 75 Open webOS components. This totals over 450,000 lines of code. ... The source code for Open webOS can be found in Open webOS repositories on GitHub. Combining today's components with those from the previous releases, Open webOS can now be ported to new devices.' HP also reaffirmed plans to continue work on Open webOS, and to bring support for Qt5, WebKit2, open source media components, and more."

MojoKid writes "The backlash against Windows 8 from various developers continues, but this time a game's creator isn't just expressing discontent. Notch, the developer behind smash hit Minecraft, has declared that he won't be working with Microsoft to certify Minecraft for Windows 8. Note that this doesn't mean Minecraft won't run on Windows 8. The certification process in question is Microsoft's mandatory rules for submitting content to the Windows game store. In order to be listed there, an application must be Metro-compatible and conform to a laundry list of other conditions. The real problem with Windows 8 is that it locks ARM users into a second class experience. If you buy an x86 tablet, you can download programs from SourceForge, GitHub, or any file mirror. If you're an ARM user, you can download programs from the Microsoft store and that's it. The bifurcated permission structure is the problem, and it makes WinRT tablets categorically impossible to recommend for anyone who values the ability to install whatever software they please."

First time accepted submitter Chris453 writes "A U.S. appeals court on Friday ruled that Google Inc's Motorola Mobility unit cannot enforce a patent injunction that it obtained against Microsoft Corp in Germany, diminishing Google's leverage in the ongoing smartphone patent wars. Motorola won an injunction against Microsoft in May using their H.264 patents. Apparently the U.S. federal justices in California have worldwide jurisdiction over all court cases — Who knew? Maybe that is why Apple keeps winning lawsuits..."

Thornburg writes "There is a free font available which has been designed to make it easier for people with dyslexia to read. DailyTech has a piece which pulls together a BBC interview and blog postings by the designer, Abelardo Gonzalez, who received a C&D letter from another font designer who charges $69 for his dyslexia related font."

J053 writes "FARS, the Iranian news agency, ran a story about a Gallup poll which showed that 'the overwhelming majority of rural white Americans said they would rather vote for Iranian president Mahmoud Ahmadinejad than U.S. president Barack Obama.' '"I like him better," said West Virginia resident Dale Swiderski, who, along with 77 percent of rural Caucasian voters, confirmed he would much rather go to a baseball game or have a beer with Ahmadinejad.' Only problem was, it was a story from The Onion. Not only that, they took credit for it! The Onion responded by stating that 'Fars is a subsidiary and has been our Middle Eastern bureau since the mid 1980s.'"

Reader intellitech points to an article at National Geographic, from which he excerpts: "If astronomers' early predictions hold true, the holidays next year may hold a glowing gift for stargazers—a superbright comet, just discovered streaking near Saturn. Even with powerful telescopes, comet 2012 S1 (ISON) is now just a faint glow in the constellation Cancer. But the ball of ice and rocks might become visible to the naked eye for a few months in late 2013 and early 2014—perhaps outshining the moon, astronomers say. The comet is already remarkably bright, given how far it is from the sun, astronomer Raminder Singh Samra said. What's more, 2012 S1 seems to be following the path of the Great Comet of 1680, considered one of the most spectacular ever seen from Earth."

An anonymous reader writes "A new paper from Professor Jason Mazzone at the University of Illinois calls for federal laws to regulate what happens to digital accounts after the account holder's death. Mazzone argues that Facebook and other online services have policies for deceased users' accounts that do not adequately protect the individual property and privacy interests at stake. The full text of the paper (called "Facebook's Afterlife") is also available: "
