Submission + - How MIT and Caltech's coding breakthrough could accelerate mobile network speeds

Submitted by colinneagle
colinneagle writes: What if you could transmit data without link layer flow control bogging down throughput with retransmission requests, and also optimize the size of the transmission for network efficiency and application latency constraints? In a Network World post, blogger Steve Patterson breaks down a recent breakthrough in stateless transmission using Random Linear Network Coding, or RLNC, which led to a joint venture between researchers at MIT, Caltech, and the University of Aalborg in Denmark called Code On Technologies.

The RLNC-encoded transmission improved video quality because packet loss in the RLNC case did not require the retransmission of lost packets. The RLNC-encoded video was downloaded five times faster than the native video stream time, and the RLNC-encoded video streamed fast enough to be rendered without interruption.

In over-simplified terms, each RLNC encoded packet sent is encoded using the immediately earlier sequenced packet and randomly generated coefficients, using a linear algebra function. The combined packet length is no longer than either of the two packets from which it is composed. When a packet is lost, the missing packet can be mathematically derived from a later-sequenced packet that includes earlier-sequenced packets and the coefficients used to encode the packet.

Submission + - Robots Are Strong: The Sci-Fi Myth of Robotic Competence (popsci.com) 1

malachiorion writes: When it comes to robots, most of us are a bunch of John Snow know-nothings. With the exception of roboticists, everything we assume we know is based on science fiction, which has no reason to be accurate about its iconic heroes and villains, or journalists, who are addicted to SF references, jokes and tropes. That's my conclusion, at least, after a story I wrote Popular Science got some attention—it asked whether a robotic car should kill its owner, if it means saving two strangers. The most common dismissals of the piece claimed that robo-cars should simply follow Asimov's First Law, or that robo-cars would never crash into each other. These perspectives are more than wrong-headed—they ignore the inherent complexity and fallibility of real robots, for whom failure is inevitable. Here's my follow-up story, about why most of our discussion of robots is based on make-believe, starting with the myth of robotic hyper-competence. Bishop

Submission + - Driverless cars could cripple law enforcement budgets (networkworld.com)

Submitted by colinneagle
colinneagle writes: Google’s driverless cars have now combined to drive more than 700,000 miles on public roads without receiving one citation, The Atlantic reported this week. While this raises a lot of questions about who is responsible to pay for a ticket issued to a speeding autonomous car – current California law would have the person in the driver’s seat responsible, while Google has said the company that designed the car should pay the fine – it also hints at a future where local and state governments will have to operate without a substantial source of revenue.

Approximately 41 million people receive speeding tickets in the U.S. every year, paying out more than $6.2 billion per year, according to statistics from the U.S. Highway Patrol published at StatisticBrain.com. That translates to an estimate $300,000 in speeding ticket revenue per U.S. police officer every year.

State and local governments often lean on this source of income when they hit financial trouble. A study released in 2009 examined data over a 13-year period in North Carolina, finding a “statistically significant correlation between a drop in local government revenue one year, and more traffic tickets the next year,” Popular Science reported.

So, just as drug cops in Colorado and Washington are cutting budgets after losing revenue from asset and property seizures from marijuana arrests, state and local governments will need to account for a drastic reduction in fines from traffic violations as autonomous cars stick to the speed limit.

Submission + - Bell Labs offers $100,000 prize for game-changing information technology (networkworld.com) 1

Submitted by coondoggie
coondoggie writes: One of the iconic research facilities in the world — Bell Labs — today said it would offer $100,00 in prizes for researchers that have innovative ideas that can alter the information and communications technology field by a factor of 10. If that sounds pretty wide open, it is, as the lab is looking for all manner of advanced ideas in areas from web applications, cloud services, cryptography, network mathematics and security to software-defined networks, sustainability, wireless systems and coding theory.

Submission + - Gun Rights Groups Say They Don't Oppose Smart Guns, Just Mandates (computerworld.com) 1

Submitted by Lucas123
Lucas123 writes: When two gun stores attempted to sell the nation's first integrated smart gun, the iP1, gun advocacy groups were charged in media reports with organizing protests that lead to the stores pulling the guns from their shelves or reneging on their promise to sell them in the first place. But, the National Rifle Association and the National Shooting Sports Foundation say they do not oppose smart gun technology, which they call "authorized user recognition" firearms. "We do oppose any government mandate of this technology, however. The marketplace should decide," Mike Bazinet, a spokesman for the NSSA, wrote in an email reply to Computerworld. However, the argument for others goes that if stores begin selling smart guns, then legislators will draft laws requiring the technology.

Submission + - The 69 Words GM Employees Can Never Say (aol.com)

Submitted by bizwriter
bizwriter writes: General Motors put together its take on a George Carlin list of words you can't say. Engineering employees were shown 69 words and phrases that were not to be used in emails, presentations, or memos. They include: defect, defective, safety, safety related, dangerous, bad, and critical. You know, words that the average person, in the context of the millions of cars that GM has recalled, might understand as indicative of underlying problems at the company. Oh, terribly sorry, "problem" was on the list as well.

Submission + - Why should Red Hat support competitors' software? (networkworld.com)

Submitted by colinneagle
colinneagle writes: The Wall Street Journal recently reported that, based on documents it reviewed, Red Hat "has chosen not to provide support to its commercial Linux customers if they use rival versions of OpenStack." But the big question is: Why would customers have expected that in the first place? Gartner analyst Lydia Leong told Network World that Red Hat isn't really doing anything wrong here. Customers shouldn't have an expectation that Red Hat would support competitors' software. "The norm would be to expect that non-Red Hat software is treated like any other third-party software," Leong says.

If Red Hat has done anything wrong, it's that it has not clearly articulated its positioning and support for non-Red Hat OpenStack distros. Red Hat did not immediately respond to a question asking for a clarification on its support policy.

The complication in all this comes from the fact that OpenStack is an open source project and there are misconceived notions that all OpenStack clouds are interoperable with one another. But Leong says just because OpenStack is open source doesn't change the expectations around vendors supporting competitors' products.

Each vendor — HP, Red Hat, Rackspace, IBM — has its own commercial interests at play here. Of course Red Hat will integrate their OpenStack distro with RHEL — that's how it makes money. And HP will do the same with its hardware. There are no purely altruistic open source companies that offer free distributions that are interoperable across all vendors.

Submission + - Microsoft Research's gesture keyboard could kill the mouse (networkworld.com)

Submitted by colinneagle
colinneagle writes: The Type–Hover–Swipe keyboard is a slim keyboard with gesture control sensors embedded between its keys. When you want to do some basic mouse movements, like scrolling up and down, simply raise your hand from the keyboard and make a gentle motion. In a demo video showing it in action, switching between apps seemed as simple as hovering over the keyboard, More interesting is the racing game simulation, where you basically hold your hands over the keyboard in a driving position. That did look a little clumsy, but as Microsoft says, the sensors are only 64 pixels, so it's fairly low res. There are other methods to compensate for this and recognize proper input.

As always, this is a work in progress. The keyboard has no release date, and there's no promise it will be released, or even be released in the form demonstrated. But if it can spare users the waste of time of shifting to the keyboard, then that will be a benefit for all.

Submission + - Why Hollywood's Best Robot Stories Are About Slavery (popsci.com)

Submitted by malachiorion
malachiorion writes: On the occasion of Almost Human's cancellation (and the box office flopping of Transcendence), I tried to suss out what makes for a great, and timeless Hollywood robot story. The common thread seems to be slavery, or stories that use robots and AI as completely blatant allegories for the discrimination and dehumanization that's allowed slavery to happen, and might again. My analysis for Popular Science, including a defense (up to a point!) of HAL 9000's murder spree.

Submission + - Ask Slashdot: How Do You Tell A Compelling Story About IT Infrastructure?

Submitted by Anonymous Coward
An anonymous reader writes: Every month we submit status reports to upper management. On the infrastructure side, these reports tend to be "Hey, we met our service level agreements ... again." IT infrastructure is now a lot like the electric company. Nobody thanks the electric company the lights come on but they have plenty of colorful adjectives to describe them when the power is off.

What is the best way to construct a compelling story for upper management so they'll appreciate the hard work that an IT department does. They don't seem particularly impressed with functioning systems because they expect functioning systems. The extensive effort to design and implement reliable systems has also made IT boring and dull. What types of summaries can you provide upper management to help them appreciate IT infrastructure and the money they spend on the services it provides?

Submission + - Microsoft cheaper to use than open source software, UK CIO says (networkworld.com)

Submitted by colinneagle
colinneagle writes: Jos Creese, CIO of the Hampshire County Council, told Britain's "Computing" publication that part of the reason is that most staff are already familiar with Microsoft products and that Microsoft has been flexible and more helpful.

"Microsoft has been flexible and helpful in the way we apply their products to improve the operation of our frontline services, and this helps to de-risk ongoing cost," he told the publication. "The point is that the true cost is in the total cost of ownership and exploitation, not just the license cost."

Creese went on to say he didn't have a particular bias about open source over Microsoft, but proprietary solutions from Microsoft or any other commercial software vendor "need to justify themselves and to work doubly hard to have flexible business models to help us further our aims."

Submission + - MIT students to receive $100 in Bitcoin (networkworld.com)

Submitted by colinneagle
colinneagle writes: The MIT Bitcoin Club is handing out $100 in the cryptocurrenty to MIT undergrads next September. The club’s co-founder Jeremy Rubin gave a pretty convincing reason for the giveaway:

"Giving students access to cryptocurrencies is analogous to providing them with internet access at the dawn of the internet era."

That gets at the main point, which is to encourage the students to test the technology and come up with applications for it. Even with the Mt. Gox debacle and the other issues surrounding Bitcoin's stability and value, its potential as a technological platform remains massive.

netbuzz writes: A band called netcat is generating buzz in software circles by releasing its debut album as a Linux kernel module (among other more typical formats.) Why? “Are you ever listening to an album, and thinking ‘man, this sounds good, but I wish it crossed from user-space to kernel-space more often!’ We got you covered,” the band says on its Facebook page. “Our album is now fully playable as a loadable Linux kernel module.”

Submission + - ARIN runs out of IPv4 addresses (networkworld.com)

Submitted by colinneagle
colinneagle writes: After IANA allocated the final IPv4 addresses to the five Regional Internet Registries (RIRs) on February 3, 2011, the RIRs have been running out of IPv4 addresses over the past three years. APNIC ran out on April 15, 2011; RIPE NCC ran out on September 14, 2012; and now ARIN has run out on April 23, 2014.

After today’s announcement by ARIN, they have now entered Phase 4 of their IPv4 exhaustion plan. Their Number Resource Policy Manual (NRPM) defines the process that organizations can request IPv4 addresses. At this moment, IPv4 addresses will only be allocated on an emergency basis. This means that an ISP can make one final request for a /22, but after that they will not get any more address space.

This may be concerning for many organizations that intend to continue using IPv4 for decades to come. There are probably no organizations in the ARIN territories that are actively planning to stop using IPv4 at some point in the future. Organizations that are desperate for addresses can purchase them through the address transfer marketplace. ARIN permits address transfers to take place, but you must follow their rules as part of the address transfer process. Over time, the price of an IPv4 address will increase from $15 to $30 today to well over $100 in the not-so-distant future.

Submission + - Americans are scared about the future of drones, robots, and wearables (networkworld.com)

Submitted by colinneagle
colinneagle writes: Findings from a recent Pew study on Americans' opinions on future technology and science: 65% think it would be a change for the worse if lifelike robots become the primary caregivers for the elderly and people in poor health. 63% think it would be a change for the worse if personal and commercial drones are given permission to fly through most U.S. airspace. 53% of Americans think it would be a change for the worse if most people wear implants or other devices that constantly show them information about the world around them.

The drone concern is to be expected, from both a privacy and a safety perspective. Last year, a small Colorado town tried to issue permits for residents to shoot down airborne drones, and came pretty close to making it legal. And just last week, a drone fell out of the air at a triathlon in Australia; an ambulance crew had to pick pieces of the drone's propeller out of her head. Compare this problem with Amazon’s vision of constant drone deliveries and you have a recipe for a country full of concerned parents.

The wearable concern is just another sign of privacy concerns going mainstream. Google Glass has seen some serious backlash lately, with even physical violence and theft against those who wear them in public. The study just illustrates how widespread this contempt goes.

One issue I was surprised not to see was concern over the impact of robots and drones on jobs for humans. A 2013 Oxford study estimated that as many as 47% of human jobs in the U.S. can be automated, taken over by robots or drones that don’t require a wage (let alone a minimum wage) and can work round-the-clock.
