SpaceX's New Combustion Technologies 5

Posted by samzenpus
from the try-this-one dept.
An anonymous reader shares this story that takes a look at some of the advances SpaceX is working on. "Getting a small group of human beings to Mars and back is no easy task, we learned at the recent GPU Technology Conference in San Jose hosted graphics chip and accelerator maker Nvidia. One of the problems with such a mission is that you need a very large and efficient rocket engine to get the amount of material into orbit for the mission, explained Adam Lichtl, who is director of research at SpaceX and who with a team of a few dozen programmers is try to crack the particularly difficult task of better simulating the combustion inside of a rocket engine. You need a large engine to shorten the trip to Mars, too....Not only do you need a lot of stuff to get to Mars and sustain a colony there, but you also need a way to generate fuel on Mars to come back to Earth. All of these factors affect the design of the rocket engine....As if these were not problems enough, there is another really big issue. The computational fluid dynamics, or CFD, software that is used to simulate the movement of fluids and gases and their ignition inside of all kinds of engines is particularly bad at assisting in rocket engine design. 'Methane is a fairly simple hydrocarbon that is perfectly good as a fuel,' Lichtl said. 'The challenge here is to design an engine that works efficiently with such a compound. But rocket engine CFD is hard. Really hard.'"

Why the Final Moments Inside a Cockpit Are Heard But Not Seen 70

Posted by Soulskill
from the keeps-crash-investigators-employed dept.
jones_supa writes: There's no video footage from inside the cockpit of the Germanwings flight that left 150 people dead — nor is such footage recorded from any other commercial airline crash in recent years. Unlike many other vehicles operating with heightened safety concerns, airline cockpits don't come with video surveillance. The reason, in part, is that airline pilots and their unions have argued vigorously against what they see as an invasion of privacy that would not improve aviation safety. The long debate on whether airplane cockpits in the U.S. should be equipped with cameras dates back at least 15 years, when the National Transportation Safety Board (NTSB) first pushed regulators to require video monitoring following what the agency called "several accidents involving a lack of information regarding crewmember actions and the flight deck environment." The latest NTSB recommendation for a cockpit image system (PDF) came in January 2015. Should video streams captured inside the plane become a standard part of aviation safety measures?

angry tapir writes: The Australian government has revealed its (previously mooted) proposed legislation that will allow copyright holders to apply for court orders that will force ISPs to block access to pirate websites. It forms part of a broader Australian crackdown on online copyright infringement, which also includes a warning notice scheme for alleged infringers. They're not the only ones getting on board with website blocking — a judge in Spain ruled that local ISPs must block access to The Pirate Bay.

from the double-as-a-minature-space-elevator dept.
An anonymous reader writes: A light bulb made from graphene — said by its UK developers to be the first commercially viable consumer product using the super-strong carbon — is to go on sale later this year. The dimmable LED bulb with a graphene-coated filament was designed at Manchester University, where the material was discovered in 2004. It is said to cut energy use by 10% and last longer owing to its conductivity. It is expected to be priced lower than current LED bulbs, which cost about £15 (~$22) each.

You can get freeze dried food, AR15's, enough ammo to start a small police action (at least here in the U.S. -- YMMV), but it has been difficult to get a modern, portable flamethrower until now. CNET has a brief explanation on the XM42, which doubled its Indiegogo funding target in just a few days.

Another Patent Pool Forms For HEVC 62

Posted by Soulskill
from the money-to-be-squeezed dept.
An anonymous reader writes: A new patent pool, dubbed HEVC Advance, has formed for the HEVC video codec. This pool offers separate licensing from the existing MPEG LA HEVC patent pool. In an article for CNET, Stephen Shankland writes, "HEVC Advance promises a 'transparent' licensing process, but so far it isn't sharing details except to say it's got 500 patents it describes as essential for using HEVC, that it plans to unveil its license in the third quarter, and that expected licensors include General Electric, Technicolor, Dolby, Philips and Mitsubishi Electric. The group's statement suggested that some patent holders weren't satisfied with the money they'd make through MPEG LA's license. One of HEVC Advance's goals is 'delivering a balanced business model that supports HEVC commercialization.' ... HEVC Advance and MPEG LA aren't detailing what led to two patent pools, an outcome that undermines MPEG LA's attempt to offer a convenient 'one-stop shop' for companies needing a license." Perhaps this will lead to increased adoption of royalty-free video codecs such as VP9. Monty Montgomery of Xiph has some further commentary.

Ikea Refugee Shelter Entering Production 60

from the ships-with-9-randomly-chosen-and-superfluous-bolts,-screws,-and-dowels dept.
jones_supa writes: Ikea's line of flatpack refugee shelters are going into production, the Swedish furniture maker announced this week. The lightweight Better Shelter was developed under a partnership between the Ikea Foundation and the United Nations High Commissioner for Refugees (UNHCR), and beta tested among refugee families in Ethiopia, Iraq, and Lebanon. Each unit takes about four hours to assemble and is designed to last for three years — far longer than conventional refugee shelters, which typically last about six months. The product is an important tool in the prolonged refugee crisis that has unfolded across the Middle East. The war in Syria has spurred nearly 4 million people to leave their homes. The UNHCR has agreed to buy 10,000 of the shelters, and will begin providing them to refugee families this summer.

ubrgeek writes: Slack, makers of the popular communications software, announced yesterday that they'd suffered a server breach. This follows shortly after a similar compromise of Twitch.tv, and is indicative of a growing problem facing start-up tech companies. As the NY Times reports, "Breaches are becoming a kind of rite of passage for fledgling tech companies. If they gain enough momentum with users, chances are they will also become a target for hackers looking to steal, and monetize, the vast personal information they store on users, like email addresses and passwords."

UK Licensing Site Requires MSIE Emulation, But Won't Work With MSIE 143

Posted by timothy
from the strange-circlings-back dept.
Anne Thwacks writes The British Government web site for applying for for a licence to be a security guard requires a plugin providing Internet Explorer emulation on Firefox to login and apply for a licence. It won't work with Firefox without the add-on, but it also wont work with Internet Explorer! (I tried Win XP and Win7 Professional). The error message says "You have more than one browser window open on the same internet connection," (I didn't) and "to avoid this problem, close your browser and reopen it." I did. No change.

I tried three different computers, with three different OSes. Still no change. I contacted their tech support and they said "Yes ... a lot of users complain about this. We have known about it since September, and are working on a fix! Meanwhile, we have instructions on how to use the "Fire IE" plugin to get round the problem." Eventually, I got this to work on Win7pro. (The plugin will not work on Linux). The instructions require a very old version of the plugin, and a bit of trial and error is needed to get it to work with the current one. How can a government department concerned with security not get this sort of thing right?"

New Screenshots Detail Spartan Web Browser For Windows 10 Smartphones 62

Posted by timothy
from the evolution-continues dept.
MojoKid writes One of the most anticipated new features in Windows 10 is the Spartan web browser, which will replace the long-serving Internet Explorer. We've seen Spartan in action on the desktop/notebook front, but we're now getting a closer look at Spartan in action on the mobile side thanks to some newly leaked screenshots. Perhaps the biggest change with Spartan is the repositioning of the address bar from the bottom of the screen to the top (which is also in line with other mobile browsers like Safari and Chrome). The refresh button has also been moved from its right-hand position within the address bar to a new location to the left of the address bar. Reading Lists also make an appearance in this latest build of Spartan along with Microsoft's implementation of "Hubs" on Windows 10 for mobile devices.

Iowa's Governor Terry Branstad Thinks He Doesn't Use E-mail 238

Posted by timothy
from the bizarro-er-and-bizarro-er dept.
Earthquake Retrofit writes The Washington Post reports the governor of Iowa denying he uses e-mail, but court documents expose his confusion. From the article: "Branstad's apparent confusion over smartphones, apps and e-mail is ironic because he has tried to portray himself as technologically savvy. His Instagram account has pictures of him taking selfies and using Skype... 2010 campaign ads show him tapping away on an iPad. 'Want a brighter future? We've got an app for that.' Earlier this month, the governor's office announced that it had even opened an account on Meerkat, the live video streaming app." Perhaps he's distancing himself from e-mail because it's a Hillary thing.

from the one-day-will-be-on-ebay.nk dept.
An anonymous reader writes A small portable media device, costing roughly $50, is allowing North Koreans to access and view foreign media despite tight government censorship, according to a Reuters report. The 'Notel', a mashup of notebook and television, is being described as a symbol of change in the repressed society. Used to watch DVDs and shared content from USB sticks and SD cards, the media player can be easily concealed and transported among families and friends. According to correspondents in the region, as many as half of all urban North Korean households have a notel and are swapping a broad range of banned media such as soaps and TV dramas from South Korea and China, Hollywood blockbusters, and news clips — all of which is strictly forbidden by Pyongyang law.

Toshiba Announces 3D Flash With 48 Layers 42

Posted by Soulskill
from the going-to-need-an-elevator dept.
Lucas123 writes: Admitting it has bumped up against a 15 nanometer process wall, Toshiba announced it's focusing its efforts on three dimensional NAND using its Bit Cost Scalable technology (PDF) in order to increase capacity. It has dedicated a Japanese fab plant to it and developed 48-level 3D NAND, which bumps density up 33% over previous 3D NAND flash. The new 3D NAND will be able to store 128Gb of data per chip (16GB). Samsung has been mass producing 32-layer, triple-level cell (TLC) 3D NAND since last October and has incorporated it into some of its least expensive SSDs. Yesterday, Micron and Intel announced their own 32-layer 3D TLC NAND, which they claimed will lead to 10TB SSDs. While Toshiba's 3D NAND is multi-level cell (meaning it stores two bits per transistor versus three), the company does plan on developing a TLC version. Toshiba said it's not abandoning 15nm floating gate flash, but it will focus those efforts on lower capacity applications.

Behind the Scenes At a Quantum Dot Factory 35

Posted by Soulskill
from the harvesting-the-dot-crop dept.
Tekla Perry writes: In a nondescript office complex in Milpitas, Calif., Nanosys is making enough quantum dots to populate 6 million 60-inch television screens annually. "The process goes on in what looks like a microbrewery. In about half a dozen large metal tanks ... Nanosys combines cadmium and selenium and adjusts the temperature, concentration, and catalysts added to force these precursors to combine into stable crystals of cadmium selenide. Then, by readjusting the conditions, the system stops the formation of crystals and triggers the beginning of crystal growth. A computer controls the process according to a programmed “recipe;” staff members monitor the growth of the crystals by shining light on them and measuring the wavelength of the fluorescence; the smallest crystals don’t fluoresce at all, then, as the crystals get larger, the wavelength changes. Nanosys stops the process when the fluoresced light hits the target wavelength, which varies depending on what particular display industry standard that the batch of film is designed to meet."

Modern Cockpits: Harder To Invade But Easier To Lock Up 364

Posted by Soulskill
from the difficulty-with-edge-cases dept.
HughPickens.com writes: Jad Mouawad And Christopher Drew write in the NY Times that although airplane cockpits are supposed to be the last line of defense from outside aggressors, airlines have fewer options if the threat comes from within. One of the major safety protocols that actually made planes safer in the past 15 years was that the cockpits were turned into fortresses. Unfortunately, that exact advantage was exploited by the co-pilot of the Germanwings plane on Tuesday to crash it intentionally. "It is shocking to me that there was not a second person present in the cockpit," says Mark Rosenker, a former chairman of the National Transportation Safety Board. Access to the cockpit is strictly regulated in the United States. Passengers are not allowed to congregate near the cockpit door, and whenever the door is open, no one is allowed in the forward bathroom and flight attendants usually block aisle access, sometimes using a food cart. The Federal Aviation Administration mandates that a flight attendant must sit in the cockpit when either pilot steps into the passenger area; European regulations do not have a similar two-person rule, but they're now talking about creating one.

The Germanwings accident also points to potential shortcomings in how pilots are screened for mental problems, a recurring concern for an industry that demands focus and discipline in an increasingly technical job, often in stressful situations. In 2012, a well-regarded pilot with JetBlue, one of the airline's earliest employees, was physically restrained by passengers on a flight from New York to Las Vegas after displaying erratic behavior. In that case, the co-pilot locked the pilot out of the cabin and made an emergency landing in Amarillo, Tex. "Aircraft-assisted pilot suicides," as the Federal Aviation Administration calls them, are rare. They include the November 2013 crash of a Mozambique Airlines plane bound for Luanda, Angola, which bears an eerie resemblance to the Germanwings plane's demise. When the flight's co-pilot left to use the lavatory, the captain locked him out of the cockpit and manually steered the aircraft earthward. The crash of Egypt Airlines Flight 990 off Nantucket, Mass., in 1999, which killed all 217 people on board, was also caused by deliberate action, a National Transportation Safety Board investigation concluded. Experts on suicide say that the psychology of those who combine suicide with mass murder may differ in significant ways from those who limit themselves to taking their own lives.

US Air Force Overstepped In SpaceX Certification 67

Rambo Tribble writes: An internal review commissioned by Air Force Secretary Deborah James has concluded that Air Force personnel tasked with evaluating SpaceX's certification treated it as a design review, going so far as to dictate organizational changes in the company. This was judged contrary to the intention of promoting a competitive environment. The report, prepared by former Air Force Chief of Staff General Larry Welch, concluded, "The result to date has been ... the worst of all worlds, pressing the Falcon 9 commercially oriented approach into a comfortable government mold that eliminates or significantly reduces the expected benefits to the government of the commercial approach. Both teams need to adjust."

Quebec Plans To Require Website Blocking, Studies New Internet Access Tax 234

Posted by Soulskill
from the welcome-to-the-information-supertollroad,-eh dept.
An anonymous reader writes: Michael Geist reports that the Government of Quebec released its budget (PDF) yesterday featuring two Internet-related measures that are sure to attract attention and possible litigation. First, it is moving forward with plans to study a new tax on residential Internet services in order to provide support for the cultural sector. Second, the government says it will be introducing a new law requiring ISPs to block access to online gambling sites. The list of blocked sites will be developed by Loto-Quebec, a government agency. The government views this as a revenue enhancing measure because it wants to channel gamblers to its own Espacejeux, the government's own online gaming site.
