b1tbkt writes "So it seems that furniture manufacturers have not yet acknowledged the realities of modern life. Kitchen tables could benefit greatly from built-in concealable receptacles. Even more obvious is the need for electrical wiring in couches and coffee tables. I realize that there are safety (fire) concerns but as it stands most families that I know already have power cords for laptops, tables and phones draped over, under and through their couches at any given point. If someone wanted to wire their furniture with AC or some type of standardized LV DC system, what are some dangers to watch for and what, if any, specialized hardware exists for the purpose?"

New submitter TheJish writes "The RPiCluster is a 33-node Beowulf cluster built using Raspberry Pis (RPis). The RPiCluster is a little side project I worked on over the last couple months as part of my dissertation work at Boise State University. I had need of a cluster to run a distributed simulator I've been developing. The RPiCluster is the result. I've written an informal document on why I built the RPiCluster, how it was built, and how it performs as compared to other platforms. I also put together a YouTube video of it running an MPI parallel program I created to demo the RGB LEDs installed on each node as part of the build. While there have certainly been larger RPi clusters put together recently, I figured the Slashdot community might be interested in this build as I believe it is a novel approach to the rack mounting and power management of RPis."
An anonymous reader writes "Tom's Hardware reports on the Connectify Switchboard software that "divides the user's traffic between Wi-Fi, 3G/4G and Ethernet-based connections on a packet-by-packet basis. Even a single stream — such as a Netflix movie — can be split between two or three Internet connections for a higher resolution and faster buffering." As part of its Kickstarter campaign, Connectify is geolocating their backers to optimize deployment of their servers. This is a clever way for supporters to influence the project beyond pledge levels and stretch goals, and it's actually kind of fun to watch."

Article text is in Danish, but the pictures illustrate their results. The exact mechanism is still unknown (Danish original), but experts have shown interest in reproducing the experiment."
New submitter WillgasM writes "A bit of good news for American travelers, according to the New York Times: 'After years of criticism of the wireless service on its trains, Amtrak announced on Thursday that it had upgraded its cellular-based Wi-Fi using broadband technologies that will improve the speed and reliability of the Internet in its passenger cars.' So far the service has been rolled out on the high-speed Acela lines and a few routes in California, but they hope to have the rest of their trains upgraded by the end of Summer. We're still an order of magnitude away from high-speed rails in other countries, but it's nice to know someone's trying."
An anonymous reader writes "Despite the fact that I am fairly young at twenty-four years old, people see me as rather 'old school.' I regularly use Lynx, IRC, Pine, have many consoles open, and am currently typing this on an older plain black laptop that has a matte 4:3 display and no chiclet keys. As the days progress, I am coming to the realization that the 'old school' computing world that I grew up in is slowly fading away and a new world of Windows 8, Web 3.0, tablets, smart televisions, and social networking is starting to become fairly common. If there is anything I have learned, it is that most humans have a desire to throw out the old and accept the new without any sort of hesitation. Like many Slashdot users (I am sure you know who you are), I do not accept the new as easily as I probably should. How have you learned to adapt and accept things that are new and different in the world of technology and computers? If not, what are some effective strategies to utilize to keep these kids off my lawn?"
CowboyRobot writes "At the recent 2013 Open Networking Summit, Google Distinguished Engineer Amin Vahdat presented 'SDN@Google: Why and How', in which he described Google's 'B4' SDN network, one of the few actual implementations of software-defined networking. Google has deployed sets of Network Controller Servers (NCSs) alongside the switches, which run an OpenFlow agent with a 'thin level of control with all of the real smarts running on a set of controllers on an external server but still co-located.' By using SDN, Google hopes to increase efficiency and reduce cost. Unlike computation and storage, which benefit from an economy of scale, Google's network is getting much more expensive each year."
Nerval's Lobster writes "Roughly 85 percent of IT managers polled by Forrester said they would hold onto networking infrastructure longer, but vendors retire products prematurely in an effort to force customers to upgrade. In a response that may seem familiar to anyone who's ever been pressured into buying a maintenance contract—either by an enterprise vendor or a major electronics retailer—over 80 percent of the 304 respondents said they don't like the misrepresented cost savings, new fees, and inflexible pricing models—but buy the products anyway. One of the survey's interesting points is that IT decision makers aren't willing to contradict the vendor. The uncertainty seems to come from the fact that the vendor may in fact be right—and a customer who contradicts what they're saying may end up shouldering the blame if the equipment goes south. It's the 'you never got fired for buying IBM' argument, applied to the networking space. The problem, of course, is that the vendor often works for its own agenda. Do you upgrade when the vendor (or reseller) suggests you do so? Or do you stick to your own way of doing things?"
Sockatume writes "The Sunday Times has revealed that analytics firm Ipsos MORI and 4G network EE attempted to sell detailed information on 27m subscribers' activities to various parties including the UK's police forces. The data encompasses the gender, postcode and age of subscribers, the sites they visit and times they are visited, and the places and times of calls and text messages. Ipsos MORI were reportedly 'bragging that the data can be used to track people and their location in real time to within 100 meters' in negotiations. Ipsos MORI has rushed to contradict this in an effort to save face, stating that the users are anonymized and data is aggregated into groups of 50 or more, while location is only precise to 700m. Despite their prior enthusiasm, the police have indicated that they will no longer go ahead with the deal. It is not clear whether the other sales will go ahead."
Lucas123 writes "Researchers are developing machine-to-machine (M2M) communication technology that allows cars to exchange data with each other, enabling vehicles to know what the cars all around them are doing, and perhaps, where they're going. Intel is working with National Taiwan University on M2M connectivity, an idea came from caravanning — an available, but-not-yet-deployed technology that uses direct line of site infrared (IR) and a range finder in order to automatically adjust the speed of cars so they can travel at a measured distance from each other. In other words, they're electronically tethered to one another. Now, imagine a group of cars traveling down the road together as an ad hoc network, each one aware of the location, any sudden actions or even the travel route of other vehicles as uploaded to the cloud from a GPS device. 'We're even imagining in the future cars would be able to ask other cars, "Hey, can I cut into your lane?" Then the other car would let you in,' said Jennifer Healey, a research scientist with Intel."
New submitter briancox2 writes with news that all internet traffic from Syria has disappeared. Umbrella Security Labs explains: "Routing on the Internet relies on the Border Gateway Protocol (BGP). BGP distributes routing information and makes sure all routers on the Internet know how to get to a certain IP address. When an IP range becomes unreachable it will be withdrawn from BGP, this informs routers that the IP range is no longer reachable. For example, one of the name servers for the DNS zone .SY is ns1.tld.sy with IP address 184.108.40.206. Normally our routers would expect a BGP route for 220.127.116.11/18. Currently that route has disappeared and we no longer have a way to reach the nameservers for .SY that reside in Syria. ... Currently there are just three routes in the BGP routing tables for Syria, while normally it’s close to eighty. ... Effectively, the shutdown disconnects Syria from Internet communication with the rest of the world."
halfEvilTech writes "CenturyLink, the nation's third largest telco network, is experiencing an outage of its broadband service nationwide, leaving its support systems overwhelmed and even causing its website to hit a few snags this morning. The company, which at last count has 5.8 million broadband subscribers, has no estimates yet on how long it will take to restore service." CenturyLink is the company that will be providing the Defense Department with the equivalent of Internet2.
judgecorp writes "BT Retail has started testing Carrier Grade NAT (CGNAT) with its customer. CGNAT is a controversial practice, in which IP addresses are shared between customers, limiting what customers can do on the open Internet. Although CGNAT goes against the Internet's original end-to-end principles, ISPs say they are forced to use it because IPv4 addresses are running out, and IPv6 is not widely implemented. BT's subsidiary PlusNet has already carried out CGNAT trials, and now BT is trying it on "Option 1" customers who pay for low Internet usage."

Unlike current quantum networks that only allow point-to-point networking, the system at Los Alamos combines traditional and quantum links to route messages through a hub while retaining the security advantages of quantum networking.
New submitter gagol writes "I recently took a position at a small industrial equipment manufacturer. We are looking to buy a new ERM software package and my boss, who is looking forward to buy the thing, knows nothing about computers or software.

I am thinking: basic components and architecture -> networking -> software -> proprietary vs open source. What do you think?"
An anonymous reader writes with a bit from the Asbury Park Press: "'Devastated and wiped out by superstorm Sandy, Verizon has no plans to rebuild its copper-line telephone network in Mantoloking. Instead, Verizon says Mantoloking is the first town in New Jersey, and one of the few areas in the country, to have a new service called Verizon Voice Link. Essentially, it connects your home's wired and cordless telephones to the Verizon Wireless network.' So no copper or fiber to a fairly densely populated area. Comcast will now be the only voice/data option with copper to the area."
An anonymous reader writes "Modern warfare these days is all about a 'networked environment.' But what happens when such things that make a modern military work breakdown? How would America's armed forces fight if their computers crashed, could not communicate, or were hit with massive viruses? What then? 'There's wisdom in science fiction. The conceit behind the reboot of the sci-fi epic Battlestar Galactica was that networking military forces exposes them to disaster unless commanders and weapons designers think ahead to the repercussions should an enemy exploit or break the network. The mechanical Cylons, arch foes of humanity, are able to crush the humans' battle fleet and bombard their home worlds with nukes by insinuating viruses into networked computers. They sever contact between capital ships and their fighter forces, and they shut down the fleet's and planets' defenses. Having lost the habit of fighting without networked systems, human crews make easy pickings for Cylon predators.'"
SternisheFan sends this excerpt from MIT's Technology Review: "The first comprehensive and large scale smart grid is now operating. The $800 million project, built in Florida, has made power outages shorter and less frequent, and helped some customers save money, according to the utility that operates it. ... Dozens of utilities are building smart grids — or at least installing some smart grid components, but no one had put together all of the pieces at a large scale. Florida Power & Light's project incorporates a wide variety of devices for monitoring and controlling every aspect of the grid, not just, say, smart meters in people's homes. ... Many utilities are installing smart meters — Pacific Gas & Electric in California has installed twice as many as FPL, for example. But while these are important, the flexibility and resilience that the smart grid promises depends on networking those together with thousands of sensors at key points in the grid — substations, transformers, local distribution lines, and high voltage transmission lines. (A project in Houston is similar in scope, but involves half as many customers, and covers somewhat less of the grid.) In FPL's system, devices at all of these places are networked — data jumps from device to device until it reaches a router that sends it back to the utility — and that makes it possible to sense problems before they cause an outage, and to limit the extent and duration of outages that still occur. The project involved 4.5 million smart meters and over 10,000 other devices on the grid."
coondoggie writes "Even the often far-reaching researchers at Defense Advanced Research Projects Agency (DARPA) seems to think this one is a stretch: Develop what's known as mobile ad-hoc wireless technology that lets 1000-5000 nodes connect simultaneously and securely in the field. For the past 20 years, researchers have unsuccessfully used Internet-based concepts in attempts to significantly scale mobile ad hoc networks, DARPA said. A constraint with current examples is they can only scale to around 50 nodes before network services become ineffective."
darthcamaro writes "Every networking vendor today is talking about Software Defined Networking (SDN). The basic idea is that the control of the underlying networking hardware is abstracted by software. Martin Casado helped to come up with the whole topic with his 2005 Stanford thesis (PDF). Eight years later after selling his startup Nicira to VMware for $1.2 Billion, Casado sees the term SDN meaning everything and nothing to all people. From the article: '"I actually don't know what SDN means anymore, to be honest," Casado said. Casado noted that the term SDN was coined in 2009 and at the time it did mean something fairly specific. "Now it is just being used as a general term for networking, like all networking is SDN," Casado said. "SDN is now just an umbrella term for, cool stuff in networking."'"
