Engineer Gets Tired Of Waiting For Telecom Companies To Wire His town -- So He Does It Himself (backchannel.com) 106

Gurb, 75 kilometers north of Barcelona, is a quiet farming community of 2,500. It has suddenly become a popular place, thanks to being the birthplace of Guifi.net, one of the world's "most important experiments in telecommunications." It was built by an engineer who got tired of waiting for Telefonica, the Spanish telecom giant, to provide internet access to the people of his community. At first he wanted an internet access for himself, but it soon became clear that he also wanted to help his neighbors. Guifi has grown from a single wifi node in 2004, to 30,000 working nodes today, including some fiber connections, with thousands more in the planning stages. An article on Backchannel today documents the tale of Guifi. From the article: The project is a testament to tireless efforts -- in governance, not just in adding hardware and software -- by Ramon Roca (the engineer who started it) and his colleagues. They've been unwavering in their commitment to open access, community control, network neutrality, and sustainability. In 2004, he bought some Linksys WiFI hackable routers with a mission to get himself and his neighbors connected to the Internet. This is how he did it: Roca turned on a router with a directional antenna he'd installed at the top of a tall building near the local government headquarters, the only place in town with Internet access -- a DSL line Telefonica had run to municipal governments throughout the region. The antenna was aimed, line of sight, toward Roca's home about six kilometers away. Soon, neighbors started asking for connections, and neighbors of neighbors, and so on. Beyond the cost of the router, access was free. Some nodes were turned into "supernodes" -- banks of routers in certain locations, or dedicated gear that accomplishes the same thing -- that could handle much more traffic in more robust ways. The network connected to high-capacity fiber optic lines, to handle the growing demand, and later connected to a major "peering" connection to the global Internet backbone that provides massive bandwidth. Guifi grew, and grew, and grew. But soon it became clear that connecting more and more nodes wasn't enough, so he created a not-for-profit entity, the Guifi.net Foundation. The foundation, thanks to its cause and a cheerful community, has received over a million Euros to date -- from various sources including several levels of government. But as the article notes, a million Euros is a drop in the bucket next to the lavish subsidies and favors that state-approved monopolies such as Telefonica have enjoyed for decades. The article adds: The Guifi Foundation isn't the paid provider of most Internet service to end-user (home and business) customers. That role falls to more than 20 for-profit internet service providers that operate on the overall platform. The ISPs share infrastructure costs according to how much demand they put on the overall system. They pay fees to the foundation for its services -- a key source of funding for the overall project. Then they offer various kinds of services to end users, such as installing connections -- lately they've been install fiber-optic access in some communities -- managing traffic flows, offering email, handling customer and technical support, and so on. The prices these ISPs charge are, to this American (Editor's note: the author is referring to himself) who's accustomed to broadband-cartel greed, staggeringly inexpensive: 18 to 35 Euros (currently about $26-$37) a month for gigabit fiber, and much less for slower WiFi. Community ownership and ISP competition does wonders for affordability. Contrast this with the U.S. broadband system, where competitive dial-up phone access -- phone companies were obliged to let all ISPs use the lines as the early commercial Internet flourished in the 1990s -- gave way to a cartel of DSL and cable providers. Except in a few places where there's actual competition, we pay way more for much less.Read the story in its entirety here.

Op-ed: Oracle Attorney Says Google's Court Victory Might Kill the GPL (arstechnica.com) 357

Annette Hurst, an attorney at Orrick, Herrington & Sutcliffe who represented Oracle in the recent Oracle v. Google trial, has written an opinion piece for Ars Technica in which she urges developers and creators to not celebrate Google's win in the hard-fought copyright case as the decision -- if remains intact -- is poised to make them "suffer" everywhere and also the free software movement itself "now faces substantial jeopardy." As you're aware, in a verdict earlier this week, a federal court announced that Google's Android operating system didn't infringe on Oracle-owned copyrights because its re-implementation of 37 Java APIs is protected by "fair use." Hurst writes: No business trying to commercialize software with any element of open software can afford to ignore this verdict. Dual licensing models are very common and have long depended upon a delicate balance between free use and commercial use. Royalties from licensed commercial exploitation fuel continued development and innovation of an open and free option. The balance depends upon adherence to the license restrictions in the open and free option. This jury's verdict suggests that such restrictions are now meaningless, since disregarding them is simply a matter of claiming "fair use." It is hard to see how GPL can survive such a result. In fact, it is hard to see how ownership of a copy of any software protected by copyright can survive this result. Software businesses now must accelerate their move to the cloud where everything can be controlled as a service rather than software. Consumers can expect to find decreasing options to own anything for themselves, decreasing options to control their data, decreasing options to protect their privacy.

China Unveils 'Straddling Bus' Design To Beat Traffic Jams (theguardian.com) 157

An anonymous reader writes: A Beijing company has unveiled spectacularly futuristic designs for a pollution-busting, elevated bus capable of gliding over the nightmarish mega-jams for which urban China has become notorious. The "straddling bus," which owes more to Blade Runner than China's car-clogged highways, is supported by two legs that run along rails laid along the roadside. Those legs allow the Transit Explore Bus, or TEB's giant frame to glide high above the gridlock at speeds of up to 60km per hour. Equally, vehicles that are less than two metres high will be able to drive freely underneath the bus, even when it is stationary. "The biggest advantage is that the bus will save lots of road space," Song Youzhou, the project's chief engineer, told Xinhua, China's official news agency. Song claimed his buses, capable of transporting up to 1,400 commuters, could be produced for 20% of the price of an underground train and rolled out far more quickly since the supporting infrastructure was relatively simple. One TEB could replace 40 conventional buses, he said.You can watch the concept video here. Interestingly a very similar -- if not the exact same -- concept has come out of China before. Not sure what kind of developments have been made in the six years since then.

Japanese Startup Wants To Rain Down Man-Made Meteor For Tokyo Olympics (sciencealert.com) 106

A startup called Star-ALE wants to create a man-made meteor shower over the city of Tokyo for the 2020 Olympics opening ceremonies. The pyrotechnics show, Star-ALE says, will be visible from an area 200km across Japan, and the pyrotechnics will actually shower from space. Starting next year, Star-ALE will begin sending a fleet of microsatellites carrying 500 to 1000 specially-developed pellets that ignite and intensely glow as they re-enter the earth's atmosphere. ScienceAlert reports: But wonderment comes at a cost, and in this case, that cost isn't cheap. Each combustible pellet comes in at about $8,100 to produce, and that's not including the costs involved in actually launching the Sky Canvas satellite. The company has tested its source particles in the lab, using a vacuum chamber and hot gases to simulate the conditions the pellets would encounter upon re-entering Earth's atmosphere. In its testing, the particles burn with an apparent magnitude of -1, which should ensure they're clearly visible in the night sky, even in the polluted skyline of a metropolis like Tokyo.

Free Lightsaber Event Now Battling Lucasfilm's Lawyers (siliconbeat.com) 198

For eight years the arts collective Newmindspace had been staging free lightsaber battles, and in December they set a world record with 9,951 "combatants" simultaneously participating in San Francisco, Los Angeles, San Diego and Seattle. But then in January they received a letter from the copyright attorneys for the Star Wars franchise. "We immediately stopped using the words 'lightsaber,' 'Jedi,' 'Sith' and 'The Force,' " the group's co-founder told the technology blog of the San Jose Mercury News, saying they've still been "aggressively pursued" for the last three months. '''In March we received further communication stating 'The Light Battle Tour' and 'light sword' were still too close to their trademarks, and we moved to settle the dispute to avoid legal action." Their new solution involves referring to the weapons as "catblades", and they've re-branded their upcoming series of events (which begins on April 30 in San Jose) as the "Cats in Space Tour".

Comment Lacking references... (Score 1) 282

This article could be interesting if it included references to who said what and in which context. Just saying "[[tech]] is a toy." without further developing or even including at least a reference is pointless - one could come up with just about any tech as an example whenever real or not.

This article is unfortunately nothing more than a waste of time :(

Comment Re:What about... (Score 1) 152

I don't really get your comment. Of course you need to trust the signer's key which is what I mean by a "known valid version of the signer's key", and the basis for that is not another user's trust unless you really trust that user as well.

However you can look at multiple sources for the key before giving it some trust (mail archives, wayback machine, which key signed previous versions, etc). Best is to actually verify the signature in person, but that's not always possible.

Note that in any case it can't be worse that relying *only* on the checksum - without a valid signature, the checksum serves only for integrity verification, and if all you need is to check transfer integrity you really don't need anything better than MD5 as although insecure the chances of collisions is way too small for one to occur accidentally.

Microsoft Launches Bot Framework To Let Developers Build Their Own Chatbots (venturebeat.com) 81

An anonymous reader shares a report on VentureBeat: Microsoft today is introducing the Bot Framework, a new tool in preview to help developers build their own chatbots for their applications. Using this, anyone can create a text program that they can chat with. A BotBuilder software-development kit (SDK) is available on GitHub under an open-source MIT license. These bots can be implemented into a variety of applications, including Slack or Telegram or even email. "Bots are like new applications," Microsoft chief executive Satya Nadella said. "And digital assistants are meta apps, or like the new browsers. And intelligence is infused into all of your interactions. That's the rich platform that we have." Microsoft will want to tread carefully.

Comment What not to do with an exchange (Score 1) 64

Well that sounds like the solution to http://xkcd.com/792/ 's problems...

On a serious note though, I won't shed a tear for CryptoRush.in. Using the same password on a small, no-reputation mining pool as the admin access to a currency exchange!?! That's a huge fail even by the lowest security standards, and these guys should know better.

Then what about getting coins stolen from the hot wallet and not even flagging the loss? What's even the point of an offline wallet when you don't reconcile the hot wallet before adding funds to it?? Another huge neglect on their part.

I actually it's probably a good thing they're now out of business because with that level of laxity, if not now there's no doubt it would have happened later, likely with more users and bigger balances... It's just sad for those who lost their coins in the process.

Author Says It's Time To Stop Glorifying Hackers 479

First time accepted submitter Geste writes "Diane McWhorter pleads in this NYT Op-Ed piece that it's time to stop glorifying hackers. Among other things she rails against providers' tendencies to 'blame the victim' with advice on improved password discipline. Interesting, but what lesson are we to learn from someone who emails lists of passwords to herself?"
