Deb Nicholson Talks About the Open Invention Network (Video) 13 Screenshot-sm

Posted by Roblimo
from the fighting-patent-trolls-and-other-dark-forces-for-the-good-of-all-humanity dept.
The OIN (Open Invention Network) site's front page starts out by saying, "Open source software development has been one of the greatest sources of innovation. It has reduced costs, improved functionality and spurred new industries." After another few sentences it says, "Open Invention Network® is an intellectual property company that was formed to promote the Linux system by using patents to create a collaborative ecosystem." Go a little deeper, on the About page, and you learn that: "Patents owned by Open Invention Network® are available royalty-free to any company, institution or individual that agrees not to assert its patents against the Linux System. This enables companies to make significant corporate and capital expenditure investments in Linux — helping to fuel economic growth." Today's interviewee, Deb Nicholson, is the OIN's Community Outreach Director. We did a video interview with OIN CEO Keith Bergelt back in February. This one adds to what he had to say. And once again, we remind you: "...if you or your company is being victimized by any entity seeking to assert its patent portfolio against Linux, please contact [OIN] so that we can aid you in your battle with these dark forces." Make your first contact through Linux Defenders 911 -- and may the OIN be with you!

Five predictions for (Bit)coin 134

Posted by timothy
from the invest-in-apc dept.
Contributor Tom Geller writes: "I recently wrote an article about Bitcoin and the law for Communications of the Association for Computing Machinery. In researching it I ran into plenty of wishful thinkers, ridiculous greedheads, and out-and-out nutbags promising a rosy future. I also found the expected blowback from vehement naysayers who think the best way to combat crazy is with more crazy. But despite that, I walked away believing that Bitcoin — or a decentralized cryptocurrency like it (let's call it "Coin") — is here to stay. As an interested outsider to the Coin economy, and a long-time technology commentator, here's what I think its future holds." Read on for Tom's predictions.

Cumulus Releases GNU/Linux For Datacenter Routers 62

Posted by Unknown Lamer
from the scale-up dept.
alphadogg writes "Start-up Cumulus Networks this week has emerged with a Linux network operating system designed for programmable data centers like the ones Google and Facebook are building. The company's Cumulus Linux OS operating system includes IPv4 and IPv6 routing, plus data center and network orchestration hooks. Much like OpenFlow for independent, software-defined control of network forwarding, Cumulus Linux is intended to run on commodity network hardware and bring Open Source extensibility to high capacity data centers. The head of the company used to work for Cisco and Google." The distribution is based on Debian and ported to several router platforms. They claim to release most of their code Open Source, but there are at least a few proprietary bits for interfacing to the routing hardware itself.

Revisiting Amdahl's Law 51

Posted by Soulskill
from the looking-for-new-loopholes dept.
An anonymous reader writes "A German computer scientist is taking a fresh look at the 46-year old Amdahl's law, which took a first look at limitations in parallel computing with respect to serial computing. The fresh look considers software development models as a way to overcome parallel computing limitations. 'DEEP keeps the code parts of a simulation that can only be parallelized up to a concurrency of p = L on a Cluster Computer equipped with fast general purpose processors. The highly parallelizable parts of the simulation are run on a massively parallel Booster-system with a concurrency of p = H, H >> L. The booster is equipped with many-core Xeon Phi processors and connected by a 3D-torus network of sub-microsecond latency based on EXTOLL technology. The DEEP system software allows to dynamically distribute the tasks to the most appropriate parts of the hardware in order to achieve highest computational efficiency.' Amdahl's law has been revisited many times, most notably by John Gustafson."

2013 U.S. Wireless Network Tests: AT&T Fastest, Verizon Most Reliable 129

adeelarshad82 writes "For the fourth year running, PCMag sent drivers out on U.S. roads to test the nation's Fastest Mobile Networks. Using eight identical Samsung phones, the drivers tested out eight separate networks for four major carriers across 30 cities evenly spread across six regions. Using Sensorly's 2013 software, a broad suite of tests were conducted every three minutes: a 'ping' to test network latency, multi-threaded HTTP upload and download tests including separate 'time to first byte' measures, a 4MB single-threaded file download, a 2MB single-threaded file upload, the download of a 1MB Web page with 70 elements, and 100kbps and 500kbps UDP streams designed to simulate streaming media. Nearly 90,000 data cycles later, the data not only revealed the fastest networks (AT&T) and the most consistent (Verizon), but also other interesting points. The tests recorded the fastest download speed (66.11 Mbits/sec) in New Orleans and the best average in Austin (27.25 Mbits/sec), both for AT&T's LTE network. The tests also found T-Mobile's HSPA network to have the worst Average-Time-To-First-Byte, even when compared with AT&T HSPA network. Also according to the tests, Sprint's LTE network didn't even come close to competing with other LTE networks, to the point that in some cities its LTE network speed averaged less than T-Mobile's HSPA network speed."

How To Block the NSA From Your Friends List 213

Posted by Unknown Lamer
from the echo-chamber dept.
Atticus Rex writes "The fact that our social networking services are so centralized is a big part of why they fall so easily to government surveillance. It only takes a handful of amoral Zuckerbergs to hand over hundreds of millions of people's data to PRISM. That's why this Slate article makes the case for a mass migration to decentralized, free software social networks, which are much more robust to spying and interference. On top of that, these systems respect your freedom as a software user (or developer), and they're less likely to pepper you with obnoxious advertisements." On a related note, identi.ca is ditching their Twitter clone platform for pump.io which promises an experience closer to the Facebook news feed. Unfortunately, adoption seems slow since Facebook, Google, et al have an interest in preventing interoperability and it can be lonely on the distributed social network.

Bob the Super Hamste writes "The St. Paul Pioneer press is reporting that Comcast is planning on expanding its network of public WiFi hot spots in the Twin Cities area by using home internet connections and user's WiFi routers. Customers will be upgraded to new wireless routers that will have 2 wireless networks, one for the home users and one for the general public. Subscribers to Comcast's Xfinity service and customers that participate in the public WiFi program will be allowed free access to the public WiFi offered by this service. Non Comcast customers get 2 free sessions a month each lasting 1 hour with additional sessions costing money. The article mentions that a similar service already exists and is provided by the Spain-based company Fon."

An anonymous reader writes "Computerworld has an interview with an Australian startup called LIFX, producing WiFi-connected LED light bulbs. Each light bulb is a small computer running the Thingsquare distribution of the open source Contiki operating system that creates a low-power wireless mesh network between the light bulbs and connects them to the WiFi network. The wireless mesh network lets the light bulbs be controlled with a smartphone app. Through a Kickstarter project, the company has already raised a significant amount of money: over one million USD.

802.11ac: Better Coverage, But Won't Hit Advertised Speeds 107

Posted by Soulskill
from the are-you-implying-marketers-would-lie-to-us?!? dept.
New submitter jcenters writes "Apple's new AirPort routers feature the new 802.11ac protocol, promising Wi-Fi speeds in excess of 1 Gbps, but Glenn Fleishman of TidBITS explains why we are unlikely to see such speeds any time soon. Quoting: 'When Apple says that its implementation of 802.11ac can achieve up to 1.3 Gbps — and other manufacturers with beefier radio systems already say up to 1.7 Gbps — the reality is that a lot of conditions have to be met to achieve that raw data rate. And, as you well know from decades of network-technology advertising, dear reader, a “raw” data rate (often incorrectly called “theoretical”) is the maximum number of bits that can pass over a network. That includes all the network overhead as well as actual data carried in packets and frames. The net throughput is often 30 to 60 percent lower.'"

Ask Slashdot: How To Bypass Gov't Spying On Cellphones? 362

Posted by timothy
from the excuse-me-while-I-snap-this-glove dept.
First time accepted submitter jarle.aase writes "It's doable today to use a mix of virtual machines, VPN, TOR, encryption (and staying away from certain places; like Google Plus, Facebook, and friends), in order to retain a reasonable degree of privacy. In recent days, even major mainstream on-line magazines have published such information. (Aftenposten, one of the largest newspapers in Norway, had an article yesterday about VPN, Tor and Freenet!) But what about the cell-phone? Technically it's not hard to design a phone that can switch off the GSM transmitter, and use VoIP for calls. VoIP could then go from the device through Wi-Fi and VPN. Some calls may be routed trough PSTN gateways — allowing the agencies to track the other party. But they will not track your location. And they will not track pure, encrypted VoIP calls that traverse trough VPN and use anonymous SIP or XMPP accounts. Android may not be the best software for such a device, as it very eagerly phones home. The same is true for iOS and Windows 8. Actually, I would prefer a non cloud-based mobile OS from a vendor that is not in the PRISM gallery. Does such a device exist yet? Something that runs a relatively safe OS, where GSM can be switched totally off? Something that will only make an outgoing network connection when I ask it to do so?" And in the absence of a perfect solution, what do you do instead? (It's still Android and using the cell network, but Red Phone — open sourced last year — seems like a good start.)

judgecorp writes "The Demo VC funding event has hit Europe (Moscow, specifically), and it is very clear that start-ups in Europe have to compete hard for any venture capital. In its 20 year history in Silicon Valley, Demo is famous for highlighting subsequent success stories such as Netscape, Skype and Salesforce.com. Demo Europe began with a venture capitalist waxing lyrical on how the shortage of funds means he gets plenty of choice where to put his money. Promising tech start-ups have a series of hoops to jump through including brief pitches. The most promising candidates so far include a Russian social VoIP network and a shared whiteboard."

New Company Set To Resurrect the Aptera 98

Posted by timothy
from the hope-this-happens dept.
Zothecula writes "Ever since it was first unveiled in 2007, many people were captivated with the sleek, futuristic looks of the Aptera. When Aptera Motors went out of business in 2011, not having commercially produced a single vehicle, those same people were understandably disappointed. Now, word comes that a new company may be manufacturing and selling Apteras as soon as next year." Says the article: "Aptera USA has most of the original company’s prototypes, equipment, patents and designs, so it wouldn’t be starting from scratch. Given that fact, Deringer hopes that Aptera USA could be making cars as early as the first quarter of 2014. He’s currently in the process of hiring engineers, and the company has already put in an order for 1,000 bodies from its Detroit-based supplier." Until there really is a super-charger network from central Texas to California, I wish I could get one of the gas-powered (or gas-electric hybrid) Apteras. Why should Tesla have all the fun?

What Can You Find Out From Metadata? 341

from the reading-between-the-lines dept.
cervesaebraciator writes "In the wake of recent revelations from Edward Snowden, apologists for the state security apparatus are predictably hitting the airwaves. Some are even 'glad' the NSA has been doing this. A major point they emphasize is that the content of calls have remained private and it is only the metadata that they're interested in. But given how much one can tell from interpersonal connections, does the surveillance only represent a 'modest encroachments on privacy?' It is easy enough to imagine how metadata on phone calls made to and from a medical specialist could be more revealing than we'd like. But social network analysis can reveal far more. Duke sociologist Kieran Healy, in a light-hearted but telling article, shows how one father of the American Revolution could have been identified using the simplest tools of social network analysis and only a limited dataset."

Though Facebook has previously hinted at this via references to a 'humidity event' within its first data center in Prineville, Oregon, the social network's infrastructure king Jay Parikh told The Reg on Thursday that, for a few minutes in Summer, 2011, Facebook's data center contained two clouds: one powered the social network, the other poured water on it.'"

The network is reasonably complex, with splices, patches, and the general type of ad-hoc build that makes knowing where things go difficult. I'd like to implement some type of software to record where the fiber cables run, what pit number they are jointed in, which fiber is spliced to which, and what internal customer is using which fiber path through the system. Knowing what fibers are free for use is also a requirement, and I'd love to record details of what equipment was put in where, for asset and warranty tracking. Extra points if I can give Engineering access to help them design things better!"

Ask Slashdot: How Best To Disconnect Remote Network Access? 284

Posted by timothy
from the no-soup-for-you dept.
An anonymous reader writes "Is there a device to automatically disconnect network or otherwise time limit a physical connection to a network? The why? We are dealing with a production outage of large industrial equipment. The cause? The supplier, with no notice, remotely connected to the process control system and completely botched an update to their system. We are down and the vendor is inept and not likely to have us back to 100% for a few days. Obviously the main issue is that they were able to do this at all, but reality is that IT gets overridden by the Process Control department in a manufacturing business. They were warned about this and told it was a horrible idea to allow remote access all the time. They were warned many times to leave the equipment disconnected from remote access except when they were actively working with the supplier. Either they forgot to disconnect it or they ignored our warnings. The question is, is there a device that will physically disconnect a network connection after a set time? Yes, we could use a Christmas tree light timer hooked up to a switch or something like that but I want something more elegant. Something with two network jacks on it that disconnects the port after a set time, or even something IT would have to login to and enable the connection and set a disconnect timer would be better than nothing. As we know, process control workers and vendors are woefully inept/uneducated about IT systems and risks and repeatedly make blunders like connecting process control systems directly to the internet, use stock passwords for everything, don't install antivirus on windows based control computers, etc. How do others deal with controlling remote access to industrial systems?"

Private Networks For Public Safety 45

Posted by Soulskill
from the sounds-timely dept.
JonZittrain writes "Projects like the New American Foundation's Commotion are designing ad hoc mesh networking to keep communications open when governments want to censor. Former FCC Chairman Julius Genachowski and I argue that mutual-aid-based networks can be helpful for public safety, too, after attacks or natural disasters. There should be easy practices for anyone to open up an otherwise-closed Wi-Fi access point if it's still connected to broadband and is near people in trouble, and separately, to develop delay- and fault-tolerant fallback ad hoc networks so users' devices can communicate directly with one another and in a mesh. This can happen even while full packet-based ad hoc mesh is being figured out. The ideas have been developed a little in workshops at Harvard's Berkman Center and the FCC. Why not bring the human rights and public safety communities together towards a common goal?"
