Political and Technical Implications of GitTorrent 208

Posted by CmdrTaco from the distribute-this-sucka dept.
lkcl writes "The GitTorrent Protocol (GTP) is a protocol for collaborative git repository distribution across the Internet. Git promises to be a distributed software management tool, where a repository can be distributed. Yet, the mechanisms used to date to actually 'distribute,' such as ssh, are very much still centralized. GitTorrent makes Git truly distributed. The initial plans are for reducing mirror loading, however the full plans include totally distributed development: no central mirrors whatsoever. PGP signing (an existing feature of git) and other web-of-trust-based mechanisms will take over from protocols on ports (e.g. ssh) as the access control 'clearing house.' The implications of a truly distributed revision control system are truly staggering: unrestricted software freedom. The playing field is leveled in so many ways, as 'The Web Site' no longer becomes the central choke-point of control. Coming just in time for that all-encompassing Free Software revolution hinted at by The Rebellion Against Vista, this article will explain more fully some of the implications that make this quiet and technically brilliant project, GitTorrent, so important to Software Freedom, from both technical and political perspectives."

Prescription Handguns For the Elderly and Disabled Screenshot-sm 1093

Posted by samzenpus from the take-two-bullets-and-call-me-in-the-morning dept.
Repton writes "Thanks to the Second Amendment, even the elderly have the right to keep and bear arms. The problem is that many of the guns out there are a bit unwieldy for an older person to handle. However, the inventors of the Palm Pistol are planning to change all that with a weapon that is ideal for both the elderly and the physically disabled. In a statement submitted to Medgadget, the manufacturer, Constitution Arms, has revealed the following: 'We thought you might be interested to learn that the FDA has completed its "Device/Not a Device" determination and concluded the handgun will be listed as a Class I Medical Device.' Physicians will be able to prescribe the Palm Pistol for qualified patients who may seek reimbursement through Medicare or private health insurance companies."

Who Protects the Internet? 177

Posted by samzenpus from the guarding-the-tubes dept.
strikeleader writes "TechCrunch has an article from an interview with General Kevin Chilton, US STRATCOM commander and the head of all military cyber warfare. Who protects us? 'Basically no one. At most, a number of loose confederations of computer scientists and engineers who seek to devise better protocols and practices — unincorporated groups like the Internet Engineering Task Force and the North American Network Operators Group. But the fact remains that no one really owns security online, which leads to gated communities with firewalls — a highly unreliable and wasteful way to try to assure security.'"

Virtual Peace Sim Game Based On America's Army 186

Posted by ScuttleMonkey from the where-everyone-looks-like-a-victim dept.
fortapocalypse writes "Duke University in collaboration with Virtual Heroes (who created America's Army) has produced a game called Virtual Peace, the intention of which is to help the gamer develop disaster relief and conflict resolution skills. Virtual Peace also is the winner of the HASTAC/MacArthur Digital Media and Learning Competition, according to an article published by the university."

Censorship By Glut 391

Posted by ScuttleMonkey from the all-my-ideas-are-brilliant dept.
Frequent Slashdot contributor Bennett Haselton writes "A 2006 paper by Matthew Salganik, Peter Dodds and Duncan Watts, about the patterns that users follow in choosing and recommending songs to each other on a music download site, may be the key to understanding the most effective form of "censorship" that still exists in mostly-free countries like the US It also explains why your great ideas haven't made you famous, while lower-wattage bulbs always seem to find a platform to spout off their ideas (and you can keep your smart remarks to yourself)." Read on for the rest of Bennett's take on why the effects of peer ratings on a music download site go a long way towards explaining how good ideas can effectively be "censored" even in a country with no formal political censorship.

Should Taxpayers Back Cars Only the Rich Can Afford? 752

Posted by Soulskill from the five-million-dollars-per-car dept.
theodp writes "The NY Times questions the $400M in low-interest federal loans requested by Tesla Motors as part of the $25B loan package for the auto industry passed by Congress last year. 'The program is intended to encourage automakers to improve fuel efficiency, but should it be used for a purpose like this, as the 2008 Bailout of Very, Very High-Net-Worth Individuals Who Invested in Tesla Motors Act?' Tesla says it is assembling about 15 cars a week and has delivered about 80 of its $109,000 base-price Roadsters to date, many of which have gone to the Valley's billionaires and centimillionaires who are Tesla investors as well as early customers. We discussed the company's financial difficulties last month."

Houses With Tails 307

Posted by timothy from the how-about-with-roots? dept.
nnfiber writes "What if home owners could also own their Internet connection? Tim Wu, of New America Foundation and Derek Slater, Google's Policy Analyst, say this can be a new effective way to encourage broadband deployment — an important issue in 'America's economic growth.' In his post, Timothy B. Lee says: 'That might sound like a crazy idea at first blush, but Wu and Slater do a great job of explaining how it might work. The key idea is "condominium fiber," an arrangement in which a number of neighboring households pool their resources to install fiber to all the homes in their neighborhoods. Once constructed, each home would own its own fiber strand, while the shared costs of maintaining the "trunk" cable from the individual homes to a central switching location would be managed in the same way that condominium and homeowners' associations currently manage the shared areas of condos and gated communities.'"

Is Open Source Software a Race To Zero? 729

Posted by Soulskill from the at-least-i'll-beat-zeno dept.
gozunda writes "My company is an open source software vendor/developer. We maintain a popular open source project and keep ourselves afloat by producing commercial products derived from or extending the value of the core project. Over time we've seen our business model eroding as other open source projects produce free versions of the same extensions and utilities that are our bread and butter. Something that was worth $5K last year is suddenly worth $0 because the free version is just as good as the paid. This same cycle is obviously having an impact on pure-play commercial software vendors. Is open source ultimately a race to zero? In ten years will there be any cost associated with commodity (non-custom) software? If not, will there still be a 'software industry' as it exists today, or will software simply be a by-product of the operation of other industries? Is that a good thing or a bad thing? As a professional developer, do I need to fear this or feed it?"

How To Help Our Public Schools With Technology? 378

Posted by kdawson from the freedom-programmers dept.
armorer writes "I'm a programmer engaged to an inner-city public school teacher. I've been thinking for a long time now about what I can do to help close the technology gap, and I finally did something (very small) about it. I convinced my company to give me a few old computers they were replacing, refurbished them, installed Edubuntu on them, and donated them to her classroom. I also took some vacation time to go in, install everything, and give a lesson on computers to the kids. It was a great experience, but now I know first-hand how little technology these schools have. I only helped one classroom. The school needs more. (Really the whole district needs more!) And while I want to help them, I don't really know how. With Thanksgiving a week away and more holidays approaching, I suspect I'm not the only one thinking about this sort of thing. I know it's a hard problem, so I'm not looking for any silver bullets. What do Slashdot readers do? What should I be doing so that I'm more effective? How do you find resources and time to give back?"

Silverlight On the Way To Linux 475

Posted by timothy from the howl-at-the-moonlight dept.
Afforess writes "For the past two years Microsoft and Novell have been working on the 'Moonlight' project. It is a runtime library for websites that run Silverlight. It should allow PCs running Linux to view sites that use Siverlight. Betanews reports 'In the next stage of what has turned out to be a more successful project than even its creators envisioned, the public beta of Moonlight — a runtime library for Linux supporting sites that expect Silverlight — is expected within days.' Moonlight 2.0 is already in the works."

An effect tending to limit the total number of laws is a benefit, not a drawback. Better fewer, simpler, wiser laws that apply correctly to ever-broadening human experience than an ever-broadening mass of special-case rules for the each hot topic over the course of history.

Not that it's easy. All communication seems to be harder to get right tersely than verbosely. Surely legal code must be one of the hardest cases of this problem.

Apple's New MacBooks Have Built-In Copy Protection 821

Posted by timothy from the presumption-from-on-high dept.
raque writes "Appleinsider is reporting that the new MacBooks/MacBookPros have built-in copy protection. Quote: 'Apple's new MacBook lines include a form of digital copy protection that will prevent protected media, such as DRM-infused iTunes movies, from playing back on devices that aren't compliant with the new priority protection measures.' Ars Technica is also reporting on the issue. Is this the deal they had to make to get NBC back? Is this a deal breaker for Apple or will fans just ignore it to get their hands on the pretty new machines? Is this a new opportunity for Linux? And what happened to Jobs not liking DRM?"

Urine Passes NASA Taste Test 404

Posted by kdawson from the not-mine dept.
Ponca City, We love you writes "Astronauts flying aboard space shuttle Endeavour are delivering a device to the International Space Station that may leave you wondering if NASA is taking recycling too far. Among the ship's cargo is a water regeneration system that distills, filters, ionizes, and oxidizes wastewater — including urine — into fresh water for drinking or, as one astronaut puts it, 'will make yesterday's coffee into today's coffee.' The US space agency spent $250M for the water recycling equipment but with the space shuttles due to retire in two years, NASA needed to make sure the station crew would have a good supply of fresh water. The Environmental Control and Life Support Systems uses a purification process called vapor compression distillation: urine is boiled until the water in it turns to steam. In space, there's an additional challenge: steam doesn't rise, so the entire distillation system is spun to create artificial gravity to separate the steam from the brine. The water has been thoroughly tested on Earth, including blind taste tests that pitted recycled urine with similarly treated tap water. 'Some people may think it's downright disgusting, but if it's done correctly, you process water that's purer than what you drink here on Earth,' said Endeavour astronaut Heidemarie Stefanyshyn-Piper."

McColo Takedown, Vigilantes Or Neighborhood Watch? 194

Posted by CmdrTaco from the where's-batman-when-you-need-him dept.
CWmike writes "Few tears were shed when alleged spam and malware purveyor McColo was suddenly taken offline last Tuesday by its upstream service providers. But behind the scenes of the McColo case and another recent takedown of Intercage, a ferocious struggle is taking place between the purveyors of Web-based malware and loosely aligned but highly committed groups of security researchers who are out to neutralize them. Backers claim that the effort to shut down miscreant ISPs is needed because of the inability of law enforcement agencies to deal with a problem that is global in nature. But some question whether there is a hint of vigilantism behind the takedowns — even as they acknowledge that there may not be any other viable options for dealing with the problem at this point."

The Science of the Lightsaber Screenshot-sm 197

Posted by samzenpus from the the-force dept.
Smartcowboy writes "Chances are that you have seen a lightsaber at one time or another, whether on the evening news or down at the local cantina. Therefore you know that a lightsaber is an amazing and versatile device that is able to cut through nearly anything in a matter of milliseconds. Have you ever wondered how these remarkable weapons work? Where does the energy come from, and how are they able to contain that energy in a rod-like column of glowing power? In this article, you will have a chance to look inside a lightsaber and discover the source of its incredible characteristics." I was sure the blade was made from the focused hate and disappointment of the last three movies.
