Does Ethernet need new features like "stream reservation" and time synchronization to make sure time-sensitive data isn't delayed on the network? coondoggie quotes Network World: The demand from Internet of Things, automotive networking and video applications are driving changes to Ethernet technology that will make it more time-sensitive. Key to those changes are a number of developing standards but also a push this week from the University of New Hampshire InterOperability Laboratory to set up three new industry specific Ethernet Time-Sensitive Networking consortiums -- Automotive Networking, Industrial Networking, and ProAV Networking aimed at developing deterministic performance within standard Ethernet for real-time, mission critical applications. "Standards-based precise time, guaranteed bandwidth, and guaranteed worst-case latency in a converged Ethernet network is a game-changer to many industries," said Bob Noseworthy, Chief Engineer, UNH-IOL.
The article also acknowledges the work of the Avnu Alliance, which is also trying to build an ecosystem of "low-latency, time-synchronized, highly reliable synchronized networked devices using open standards through certification."Read Replies (0)

InfoWorld has identified "seven of the gnarliest corners of the programming world," which Slashdot reader snydeq describes as "worthy of large markers reading, 'Here be dragons.'" Some examples:
Multithreading. "It sounded like a good idea," according to the article, but it just leads to a myriad of thread-managing tools, and "When they don't work, it's pure chaos. The data doesn't make sense. The columns don't add up. Money disappears from accounts with a poof. It's all bits in memory. And good luck trying to pin down any of it..."NP-complete problems. "Everyone runs with fear from these problems because they're the perfect example of one of the biggest bogeymen in Silicon Valley: algorithms that won't scale."
The other dangerous corners include closures, security, encryption, and identity management, as well as that moment "when the machine runs out of RAM." What else needs to be on a definitive list of the most dangerous "gotchas" in professional programming?Read Replies (0)

Slashdot reader whoever57 writes;
Navinder Sarao, the British trader who was accused of causing the "flash crash" in 2010 and was extradited to the U.S. this week has pleaded guilty to one count of wire fraud and one count of spoofing. No details of the plea deal have been released, but it's believed that he's agreed to forfeit $13 million. Several years of jail time are also expected for Mr. Sarao.
From the Telegraph:
Sarao, a 37-year-old working out of a modest suburban home in Hounslow in west London, allegedly made tens of millions of dollars with a computer program that could automatically manipulate prices... "Navinder Sarao abused sophisticated technology to make a quick profit, and jeopardised the integrity of US financial markets," said Assistant Attorney General Leslie Caldwell.
Sentencing guidelines suggest he'll spend at least six and a half years in prison, though he faced a maximum possible sentence of 30 years and still faces the possibility of $38 million in sanctions.Read Replies (0)

Although the U.S. government "does not believe the bomb contains active nuclear material," schwit1 shares this report from the BBC:
A commercial diver may have discovered a lost decommissioned U.S. nuclear bomb off the coast of Canada. Sean Smyrichinsky was diving for sea cucumbers near British Columbia when he discovered a large metal device that looked a bit like a flying saucer. The Canadian Department of National Defence believes it could be a "lost nuke" from a US B-36 bomber that crashed in the area in 1950.... The plane was on a secret mission to simulate a nuclear strike and had a real Mark IV nuclear bomb on board to see if it could carry the payload required...
The American military says the bomb was filled with lead, uranium and TNT but no plutonium, so it wasn't capable of a nuclear explosion... Several hours into its flight, its engines caught fire and the crew had to parachute to safety... The crew put the plane on autopilot and set it to crash in the middle of the ocean, but three years later, its wreckage was found hundreds of kilometers inland.
The crew says they dumped their bomb-like cargo into the ocean first to avoid a detonation on land.Read Replies (0)

"President Obama has a political moment to pardon Manning & Snowden," WikiLeaks tweeted on Friday, adding "If not, he hands a Trump presidency the freedom to take his prize." And a new online petition is also calling for a pardon of WikiLeaks founder Julian Assange, saying Assange is "a hero and must be honoured as such," attracting over 10,000 supporters in just a few days. An anonymous reader writes:
Monday WikiLeaks also announced, "irrespective of the outcome of the 2016 U.S. Presidential election, the real victor is the U.S. public which is better informed as a result of our work." Addressing complaints that they specifically targeted Hillary Clinton's campaign, the group said "To date, we have not received information on Donald Trump's campaign, or Jill Stein's campaign, or Gary Johnson's campaign or any of the other candidates that fulfills our stated editorial criteria." But they also objected to the way their supporters were portrayed during the U.S. election, arguing that Trump and others "were painted with a broad, red brush. The Clinton campaign, when they were not spreading obvious untruths, pointed to unnamed sources or to speculative and vague statements from the intelligence community to suggest a nefarious allegiance with Russia. The campaign was unable to invoke evidence about our publications -- because none exists."
Thursday a WikiLeaks representative expressed surprise that, despite the end of the U.S. election, Julian Assange's internet connection in the Ecuadorean Embassy in London has not yet been restored.Read Replies (0)

One of the biggest cons with premium virtual-reality headsets is the fact that they need to be tethered to a powerful gaming PC or game console via annoying wires. In early September, HTC announced it was working on a method to remove the wires, and now their solution is officially available via a $220 add-on kit. UploadVR reports: HTC today announced a tether-less VR upgrade kit for its SteamVR device, made by TPCAST, one of the first of 33 companies to join the Vive X Accelerator. Speaking to UploadVR in a phone interview, [China Regional President of Vive at HTC Alvin W. Graylin] said that the experience would "greatly improve" the overall Vive experience, with no "noticeable difference" for factors like latency. The product will be available to pre-order with a standard battery, though Graylin said that a bigger battery will be sold eventually. We're told the standard battery can deliver around one and a half hours of power. The bigger battery would rest in a user's pocket. HTC expects the device to be adopted by "avid" Vive users, though it could also be useful for businesses. The upgrade kit will be available to pre-order on Vive's Chinese website "in limited quantity" for 1,499 RMB ($220.33). The kit is said to ship starting in Q1 2017. According to HTC, pre-orders go live at 7 a.m. Pacific on Friday. Graylin said anyone could order the unit from there and pay for shipping. According to HTC, in a press release, "Order fulfillment will be prioritized to existing customers who can provide a valid Vive serial number."

An anonymous reader quotes a report from Space.com: A super-powerful Earth-observing spacecraft has finally taken to the skies, nearly two months after a wildfire nixed its first launch attempt. The WorldView-4 satellite lifted off today (Nov. 11) at 1:30 p.m. EST (10:30 a.m. local time; 1830 GMT), riding a United Launch Alliance Atlas V 401 rocket from Space Launch Complex-3 at California's Vandenberg Air Force Base to a near sun-synchronous, pole-to-pole orbit. In addition, seven tiny cubesats were onboard in a "ridesharing" initiative. All of the cubesats manifested for the WorldView-4 mission are sponsored by the National Reconnaissance Office, the agency in charge of the United States' spy satellites, and are unclassified technology-demonstration programs. The Atlas-V that lofted WorldView-4 today had been scheduled to launch NASA's InSight Mars lander earlier this year, before issues with one of InSight's instruments delayed the Red Planet probe's liftoff until 2018. WorldView-4 is a multispectral, high-resolution commercial imaging satellite owned and operated by DigitalGlobe of Westminster, Colorado, and built by the aerospace company Lockheed Martin. Its mission is to provide high-resolution color imagery to commercial, government and international customers. Once in operation, WorldView-4 has a global capacity to image 260,000 square miles (680,000 square kilometers) per day. You can watch the launch video here via United Launch Alliance.Read Replies (0)

A new study published in Nature Communications has found that Earth's plant life between 2002 and 2014 has absorbed so much carbon dioxide that the buildup of CO2 in the atmosphere has slowed down, despite humans pumping out more CO2 than ever before. The study also found that between 1982 and 2009, "about 18m square kilometers of new vegetation had sprouted on Earth's surface, an area roughly twice the size of the United States." The Economist reports: In 2014 humans pumped about 35.7 billion tons of carbon dioxide into the air. That figure has been climbing sharply since the middle of the 20th century, when only about 6 billion tons a year were emitted. As a consequence, the concentration of CO2 in the atmosphere has been rising too, from about 311 parts per million (ppm) in 1950 to just over 400 in 2015. Yet the rate at which it is rising seems to have slowed since the turn of the century. According to Dr Keenan, between 1959 and 1989 the rate at which CO2 levels were growing rose from 0.75ppm per year to 1.86. Since 2002, though, it has barely budged. In other words, although humans are pumping out more CO2 than ever, less of it than you might expect is lingering in the air. Filling the atmosphere with CO2 is a bit like filling a bath without a plug: the level will rise only if more water is coming out of the taps than is escaping down the drain. Climate scientists call the processes which remove CO2 from the air "sinks." The oceans are one such sink. Photosynthesis by plants is another: carbon dioxide is converted, with the help of water and light energy from the sun, into sugars, which are used to make more plant matter, locking the carbon away in wood and leaves. Towards the end of the 20th century around 50% of the CO2 emitted by humans each year was removed from the atmosphere this way. Now that number seems closer to 60%. Earth's carbon sinks seem to have become more effective, but the precise details are still unclear. Using a mix of ground and atmospheric observations, satellite measurements and computer modeling, Dr Keenan and his colleagues have concluded that faster-growing land plants are the chief reason. That makes sense: as CO2 concentrations rise, photosynthesis speeds up. Studies conducted in greenhouses have found that plants can photosynthesis up to 40% faster when concentrations of CO2 are between 475 and 600ppm.Read Replies (0)

Researchers at Imperial College London have developed a USB stick that can measure the presence and amount of HIV in a person's blood in under 30 minutes and with 95% accuracy. The USB stick should help make testing easier in places like sub-Saharan Africa, where HIV is a serious problem and where many people live in rural regions hours or days travel away from hospitals or clinics. Also, traditional HIV testing can take days to show results, whereas the USB stick can show results in minutes. Quartz reports: The new diagnostic tool, co-created by the university and biotech company DNA Electronics, requires simply putting a single drop of blood onto a designated spot on the USB stick. The device contains a mechanism that can detect if there's any HIV genetic material -- RNA -- in the drop of blood, and if so, how much. Then, when the stick is connected to a laptop or handheld device, the data are automatically delivered to an app where the patient can quickly read his or her results. One of the most effective HIV treatments currently, called anti-retroviral treatment, reduces virus levels to near zero. However, in some cases, the virus may develop a resistance to medication or therapy, causing the virus to resurface. To catch such developments early, patients can use the devices for monitoring purposes. "The disposable test could be used by HIV patients to monitor their own treatment and help patients in remote regions of the world, where more standard HIV tests are inaccessible," the authors of the study write. For now, it's still in the proof-of-concept stage, and years away from hitting the market.Read Replies (0)

An anonymous reader quotes a report from LiveScience: In just over half of a second (0.637 seconds), the Sub1 Reloaded robot made each side of the Rubik's Cube show a single color. This breaks the previous record of 0.887 seconds achieved by an earlier version of the same machine using a different processor. German technology company Infineon staged the record attempt at the Electronica trade fair in Munich this week, as a way to highlight its self-driving-car technology. The company provided one of the Sub1 Reloaded robot's microchips. Infineon said more than 43 quintillion combinations of the Rubik's Cube's colored squares are possible. That same number of cubes would cover Earth in 275 layers, resulting in an approximately 65.6-foot-high (20 meters) layer of Rubik's Cubes, the company added. The record-breaking attempt began with the press of a button. Sensor cameras on the machine had their shutters removed, and the computer was then able to detect how the cube was scrambled. The computing chip, or the "brain" of the machine as Infineon called it, then determined the fastest solution. Commands to execute the solution were sent to six motor-controlled arms. "It takes tremendous computing power to solve such a highly complex puzzle with a machine," Infineon said in a statement. "In the case of 'Sub1 Reloaded,' the power for motor control was supplied by a microcontroller from Infineon's AURIX family, similar to the one used in driver assistance systems."Read Replies (0)

An anonymous reader quotes a report from Ars Technica: Federal investigators temporarily seized a Tor-hidden site known as Playpen in 2015 and operated it for 13 days before shutting it down. The agency then used a "network investigative technique" (NIT) as a way to ensnare site users. However, according to newly unsealed documents recently obtained by the American Civil Liberties Union, the FBI not only temporarily took over one Tor-hidden child pornography website in order to investigate it, the organization was in fact authorized to run a total of 23 other such websites. According to an FBI affidavit among the unsealed documents: "In the normal course of the operation of a web site, a user sends "request data" to the web site in order to access that site. While Websites 1-23 operate at a government facility, such request data associated with a user's actions on Websites 1-23 will be collected. That data collection is not a function of the NIT. Such request data can be paired with data collected by the NIT, however, in order to attempt to identify a particular user and to determine that particular user's actions on Websites 1-23." Security researcher Sarah Jamie Lewis told Ars that "it's a pretty reasonable assumption" that at one point the FBI was running roughly half of the known child porn sites hosted on Tor-hidden servers. Lewis runs OnionScan, an ongoing bot-driven analysis of the Tor-hidden darknet. Her research began in April 2016, and it shows that as of August 2016, there were 29 unique child porn related sites on Tor-hidden servers. That NIT, which many security experts have dubbed as malware, used a Tor exploit of some kind to force the browser to return the user's actual IP address, operating system, MAC address, and other data. As part of the operation that took down Playpen, the FBI was then able to identify and arrest the nearly 200 child porn suspects. (However, nearly 1,000 IP addresses were revealed as a result of the NIT's deployment, which could suggest that even more charges may be filed.)Read Replies (0)
