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."
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.
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."
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.
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."
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.
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.'"
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.'"
An anonymous reader writes "Today Fedora and the Seneca Centre for Development of Open Technology (CDOT) announced the release of Pidora 18, an optimized Fedora remix for the Raspberry Pi. It's based on a brand new build of Fedora for the ARMv6 architecture with greater speed and includes packages from the Fedora 18 package set. It's also the launch of the Pidora name. (The older version of Fedora for the Pi was called the Fedora Raspberry Pi Remix.)"
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."
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."
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."
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."
antdude writes "Pew Internet reports that: 'Teens are sharing more info about themselves on social media sites than they have in the past, but they are also taking a variety of technical and non-technical steps to manage the privacy of that information. Despite taking these privacy-protective actions, teen social media users do not express a high level of concern about third-parties (such as businesses or advertisers) accessing their data.'"
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.'"
The Bad Astronomer writes "A Minuteman III missile launch from California early Wednesday morning created a weird, expanding halo of light seen from the CFHT observatory on Hawaii's Mauna Kea. The third stage of the missile has ports that open and dump fuel into the near-vacuum. This cloud expands rapidly as a spherical shell, shock-exciting the air molecules and causing them to glow, creating the bizarre effect."
First time accepted submitter Bas_Wijnen writes "3D printing is being condemned in the media because of the potential for printing guns. Engineers at Michigan Tech believe there is far more potential for 3D printers to make our lives better rather than killing one another. To encourage thinking about constructive uses of 3D printing technology Michigan Tech Open Sustainability Technology (MOST) Lab and Type A Machines sponsor the first 3-D Printers for Peace Contest. Designers are encouraged to consider: If Mother Theresa of Ghandi had access to 3D printing what would they print? What kind of designs could help reduce military spending and conflict while making us all safer and more secure? Anyone in the United States may enter and there is no cost."
An anonymous reader writes "The open-source Intel Linux graphics driver has hit a milestone of now being faster than Apple's own OpenGL stack on OS X. The Intel Linux driver on Ubuntu 13.04 is now clearly faster than Apple's internally-developed Intel OpenGL driver on OS X 10.8.3. when benchmarked from a 'Sandy Bridge' class Mac Mini. Only some months ago, Apple's GL driver was still trouncing the Intel Linux Mesa driver."
astroengine writes "In a recent batch of images beamed back to Earth from Mars rover Curiosity's MAHLI camera, obvious signs of wear and tear could be seen in the 'skin' of the robot's wheels. Considering Curiosity is only 281 sols (Mars days) into its mission and roved less than a kilometer after landing, surely this doesn't bode well? Fortunately, there's good news. 'The wear in the wheels is expected,' Matt Heverly, lead rover driver for the MSL mission at NASA's Jet Propulsion Laboratory in Pasadena, Calif., told Discovery News. 'We will continue to characterize the wheels both on Mars and in the Marsyard, but we don't expect the wear to impact our ability to get to Mt. Sharp.'"
Tesla Motors announced today it has completely repaid the $465 million loan from the U.S. Department of Energy the company received in 2010. The funds were generated by Tesla through a recent sale of their stock, worth close to a billion dollars. The stock price had risen sharply after the company reported its first profitable quarter (and the stock still sits roughly 50% higher than before their earnings release). Today's payment of $451.8 million finished off both the loan's principal and its interest, nine years before the final payment was due. Tesla CEO Elon Musk said, 'I would like to thank the Department of Energy and the members of Congress and their staffs that worked hard to create the ATVM program, and particularly the American taxpayer from whom these funds originate. I hope we did you proud.'
psykocrime writes "The crazy kids at Fogbeam Labs have a new blog post positing that there is a trend towards advanced projects in NLP, Information Retrieval, Big Data and the Semantic Web moving to the Apache Software Foundation. Considering that Apache UIMA is a key component of IBM Watson, is it wrong to believe that the organization behind Hadoop, OpenNLP, Jena, Stanbol, Mahout and Lucene will ultimately be the home of a real 'Star Trek Computer'? Quoting: 'When we talk about how the Star Trek computer had “access to all the data in the known Universe”, what we really mean is that it had access to something like the Semantic Web and the Linked Data cloud. Jena provides a programmatic environment for RDF, RDFS and OWL, SPARQL and includes a rule-based inference engine. ... In addition to supporting the natural language interface with the system, OpenNLP is a powerful library for extracting meaning (semantics) from unstructured data - specifically textual data in an unstructured (or semi structured) format. An example of unstructured data would be the blog post, an article in the New York Times, or a Wikipedia article. OpenNLP combined with Jena and other technologies, allows “The computer” to “read” the Web, extracting meaningful data and saving valid assertions for later use.'" Speaking of the Star Trek computer, I'm continually disappointed that neither Siri nor Google Now can talk to me in Majel Barrett's voice.
An anonymous reader writes "Edwin Vargas, a detective with the New York City Police Department, was arrested on Tuesday for computer hacking crimes. According to the complaint unsealed in Manhattan federal court, between March 2011 and October 2012, Vargas, an NYPD detective assigned to a precinct in the Bronx, hired an e-mail hacking service to obtain log-in credentials, such as the password and username, for certain e-mail accounts. In total, he purchased access to at least 43 personal e-mail accounts belonging to 30 different individuals, including at least 19 who are affiliated with the NYPD."
AndyKrish writes "A BBC story reports that scientists at Albert Einstein College of Medicine at Yeshiva University found Vitamin C kills drug resistant tuberculosis (abstract). Though results are preliminary — the lead investigator of the study said, 'We have only been able to demonstrate this in a test tube, and we don't know if it will work in humans and in animals' — this is an exciting development in the fight against drug-resistant TB."
Aguazul2 writes "The German software giant SAP has announced it plans to recruit hundreds of people with autism within the next few years. The project has already started in India and Ireland where a total of 11 people with autism are employed by the company. The program to take on software testers, programmers and data management workers will spread across Germany, Canada and the U.S. this year. People with autism have a neural development disorder that often undermines their ability to communicate and interact socially [...] but in the world of computers the tendencies they often display such as an obsession for detail and an ability to analyze long sets of data very accurately can translate into highly useful and marketable skills."
astroengine writes "The mother of all cosmic collisions has been spotted between two galaxies containing a total of 400 billion stars, igniting the birth of 2,000 new stars per year! This incredible event was first spotted by the recently-retired Herschel infrared space observatory (abstract), a mission managed by the European Space Agency. This violent discovery isn't just awesome to look at, it could also help explain how massive, red elliptical galaxies evolved in the early universe."

인생에서, 100% 순이익을 보장하는건 없다. 1%의 지식을 나눔으로써, 가끔씩 손해볼 필요도 있다.
그대가 가진 1%의 지식만이라도 공공을 위해 포스팅하라. 손해본다는 생각이 앞선다면 그대의 인생은 힘들어질것이다.
자신이 가진 지식의 1%도 투자하지 않고, 오로지 자신의 이익만 탐하는자와는 동지가 되지마라.
만나서 대화하면 모두 좋은 사람들이지만, 유독 인터넷에서만 자신을 밝히지 않고, 좀비로 서식하는 사람들이 많다.
부지불식간[不知不識間], 좀비(하류) 인생이 될지도 모르니, 항상 자신을 경계하도록 하라.
