Ethernet Turns 40 21

Posted by timothy
from the it's-thinking-about-that-optical-sportscar dept.
alancronin writes "Four decades ago the Ethernet protocol made its debut as a way to connect machines in close proximity, today it is the networking layer two protocol of choice for local area networks (LANs), wide area networks (WANs) and everything in between. For many people Ethernet is merely the RJ45 jack on the back of a laptop, but its relative ubiquity and simplicity belie what Ethernet has done for the networking industry and in turn for consumers and enterprises. Ethernet has in the space of 40 years gone from a technology that many in the industry viewed as something not fit for high bandwidth, dependable communications to the default data link protocol."

Main US Weather Satellite Fails As Hurricane Season Looms 86

from the ok-fellas-let's-just-stick-to-the-tornadoes dept.
First time accepted submitter Rebecka writes with bad news, quoting an IB Times report: "Just as the 2013 hurricane season is about to begin, one of the U.S.' main weather satellites failed this week. The Geostationary Operational Environmental Satellite, also known as GOES-13, reportedly ceased to operate as of Tuesday, making it impossible to predict weather patterns on the East Coast." A note at NOAA's page for the GOES family of satellites says "GOES-13 imaging and sounding operations suspended. Recovery efforts for GOES-13 continue and the spacecraft health and safety are nominal. GOES-14 is being activated." You can follow the progress on the agency's page of General Satellite Messages.

Ask Slashdot: How To Determine If a Video Has Been Faked? 114

Posted by timothy
from the justice-for-marion-barry dept.
BStorm writes "The Toronto Mayor Rob Ford has been making headlines around the world, for allegedly smoking crack. This story was first broken by gawker.com, which is now crowd-funding $200,000 to buy the video in question. What do you look for to determine if a video has been faked? Of course I am only interested in the technical details and not the tawdry details related to this case ;) I live in Toronto, so the video still frame posted on Gawker certainly does look like Rob Ford."

Curiosity Rewarded: Florida Teen Heading to Space Camp, Not Jail 126

from the this-time-my-pretty dept.
Kiera Wilmot, the Florida high school student who was expelled from her school after an unauthorized science experiment was misperceived as a weapon (at least for purposes of arrest and charging), won't be going to jail. She will, though, be going to Space Camp, thanks to a crowdfunding campaign started by author and former NASA engineer Homer Hickham. All charges against her have been dropped.

A Cold Look at Cold Fusion Claims: Why E-Cat Looks Like a Hoax 202

Posted by timothy
from the judas-gets-too-little-credit dept.
In the past few days, several readers have submitted word of a paper published on Arxiv allegedly confirming the efficacy of Andrea Rossi's "E-Cat," a device Rossi says transmutes nickel into copper, producing cheap energy in the process. (Mentioned before on Slashdot.) Ethan Siegel of ScienceBlogs takes a skeptical look at the buzz surrounding this paper, and asks some seemingly obvious questions, pointing out various ways in which the cold-fusion / cheap-energy claims could be either confirmed or debunked. First time accepted submitter CdXiminez writes with a capsule of Siegel's points: "What would it take to convince a reasonable observer that you've got a controlled nuclear reaction going on here? Things not shown in the earlier report: Show that nuclear transmutation has in fact taken place; Start the device operating by whatever means you want, then disconnect all external power to it, and allow it to run; Place a gamma-ray detector around the device; Accurately monitor the power drawn from all sources to the device at all times, while also monitoring the energy output from the device at all times."

NVIDIA GeForce GTX 780 Offers 2,304 Cores For $650 110

Posted by timothy
from the that's-a-lot-of-grande-lattes dept.
Vigile writes "When NVIDIA released the GTX Titan in February, it was the first consumer graphics card to use the GK110 GPU from NVIDIA that included 2,688 CUDA cores / shaders and an impressive 6GB of GDDR5 frame buffer. However, it also had a $1000 price tag that was the limiting specification for most gamers. With today's release of the GeForce GTX 780 they are hoping to utilize more of the GK110 silicon they are getting from TSMC while offering a lower cost version with performance within spitting range. The GTX 780 uses the same chip but disables a handful more compute units to bring the shader count down to 2,304 — still an impressive bump over the 1,536 of the GTX 680. The 384-bit memory bus remains though the frame buffer is cut in half to 3GB. Overall, the performance of the new card sits squarely between the GTX Titan ($1000) and AMD's Radeon HD 7970 GHz Edition ($439), just like its price. The question is, are PC gamers willing to shell out $220+ dollars MORE than the HD 7970 for somewhere in the range of 15-25% more performance?" As you might guess, there's similarly spec-laden coverage at lots of other sites, including Tom's, ExtremeTech, and TechReport. HotHardware, too.

French Police End Missing Persons Searches, Suggest Using Facebook 68

itwbennett writes "According to an announcement on a French government website, police have stopped current searches for missing adults and will not accept new search requests. 'Such 'searches in the interests of the family' were conducted under an administrative procedure almost a century old, introduced to help families separated during the upheavals of World War I to find missing relatives,' according to the French Ministry of the Interior. In a letter to police chiefs announcing the changes, the Ministry advised them to instead 'direct people towards social networks on the Internet, which offer interesting possibilities.'"

Kim Dotcom Wants Money From Google, Twitter For 2-Factor Authentication 93

Posted by timothy
from the are-celebrities-necessary? dept.
Nyder writes "Kim Dotcom posted via Twitter, with a link to Torrentfreak, that he owns a security patent US6078908, titled 'Method for authorizing in data transmission systems.'" Techdirt points out that Dotcom isn't just asking for financial help: Instead, he's asking companies which use two-factor authentication "to help fund his defense, in exchange for not getting sued for the patent. He points out that his actual funds are still frozen by the DOJ and (more importantly) that his case actually matters a great deal to Google, Facebook and Twitter, because the eventual ruling will likely set a precedent that may impact them -- especially around the DMCA." Update: 05/23 14:23 GMT by T : Why is this relevant to Twitter? If you're not an active Twitter user, you might not realize that (after some well publicized twitter-account hijackings), the company is trying to regain some ground on security. Nerval's Lobster writes "Twitter is now offering two-factor authentication, a feature that could help prevent embarrassing security breaches. Twitter users interested in activating two-factor authentication will need to head over to their account settings page and click the checkbox beside 'Require a verification code when I sign in.'"

Terrorist Murder In London Could Revive Snooper's Charter 222

Posted by timothy
from the transparent-power-grab dept.
judgecorp writes "Supporters of the Communications Data Bill (also known as the Snooper's Charter) have lost no time in calling for the Bill to be revived, in response to yesterday's brutal murder of a soldier on the streets of Woolwich, South London. The Bill would have allowed monitoring of all online communications — including who people contact and what websites they visit — but was shelved after Deputy Prime Minister Nick Clegg opposed it, effectively splitting Britain's coalition government on the issue. Now the fear of new terrorism could rekindle support, based on the argument that even 'lone wolf' attackers use the Internet."

One-Time Pad From Caltech Offers Uncrackable Cryptography 151

from the unless-you-crack-the-glass dept.
zrbyte writes "One-time pads are the holy grail of cryptography — they are impossible to crack, even in principle. However, the ability to copy electronic code makes one-time pads vulnerable to hackers. Now engineers at the California Institute of Technology in Pasadena, have found a way around this to create a system of cryptography that is invulnerable to electronic attack. Their solution is based on a special kind of one-time pad that generates a random key through the complexity of its physical structure, namely shining a light through a diffusive glass plate."

First Government Lawsuit Against a Patent Troll 81

Posted by samzenpus
from the when-the-man-comes-around dept.
walterbyrd writes "Late last year, a vigorous and secretive patent troll began sending out thousands of letters to small businesses all around the country, insisting that they owed between $900 and $1,200 per worker just for using scanners. The brazen patent-trolling scheme, carried out by a company called MPHJ technologies and dozens of shell companies with six-letter names, has caught the attention of politicians. MPHJ and its principals may have gone too far. They're now the subject of a government lawsuit targeting patent trolling—the first ever such case. Vermont Attorney General William Sorrell has filed suit in his home state, saying that MPHJ is violating Vermont consumer-protection laws."

Why We Should Celebrate Snapchat and Encourage Ephemeral Communication 131

from the get-off-my-lawn dept.
An anonymous reader writes "Within a few months of launching, Snapchat has made an enormous and lasting impact on the culture of communication on the Internet – and we should all be grateful. They have simplified a security process enough to the point that anybody can use it, while validating the market of the next generation of privacy-preserving ephemeral communication. Most importantly, we may finally get a break from the forced permanence of the Facebook and Google world, where everything you do and share is a data point to be monetized and re-sold to the highest bidder."

Physicists Create Quantum Link Between Photons That Don't Exist At the Same Time 285

Posted by samzenpus
from the time-after-time dept.
sciencehabit writes "Physicists have long known that quantum mechanics allows for a subtle connection between quantum particles called entanglement, in which measuring one particle can instantly set the otherwise uncertain condition, or 'state,' of another particle—even if it's light years away. Now, experimenters in Israel have shown that they can entangle two photons that don't even exist at the same time. Anton Zeilinger, a physicist at the University of Vienna, says that the experiment demonstrates just how slippery the concepts of quantum mechanics are. 'It's really neat because it shows more or less that quantum events are outside our everyday notions of space and time.'"
