SpaceX Tests Its Raptor Engine For Future Mars Flights (techcrunch.com) 89

Thelasko writes: Elon Musk is preparing to unveil his plans to colonize Mars at the 67th annual International Astronautical Congress tomorrow. As a tease to his lecture, he has released some details about the Raptor engine on Twitter, including pictures. Mr. Musk states that, "Production Raptor coal is specific impulse of 382 seconds and thrust of 3 MN (~310 metric tons) at 300 bar." He goes on to note that the specific impulse spec is at Mars ambient pressure. The Raptor interplanetary engine is designed for use with Space X's Mars Colonial Transporter craft. Musk notes that the "chamber pressure runs three times what's present in the Merlin engine currently used to power Falcon 9," according to TechCrunch. "Merlin has specific impulse of 282 seconds (311 seconds in the vacuum of space), and a relatively paltry 654 kilonewton (0.6 MN) at sea level, or 716 kN (0.7 MN) in a vacuum. You can view a picture of the "Mach diamonds" here, which are visible in the engine's exhaust.

UK's Top Police Warn That Modding Games May Turn Kids into Hackers (vice.com) 147

Joseph Cox, writing for Motherboard: Last week at EGX, the UK's biggest games event, attendees got a chance to play upcoming blockbusters like Battlefield 1, FIFA 17, and Gears of War 4. But budding gamers may also have spotted a slightly more unusual sight: a booth run by the National Crime Agency (NCA), the UK's leading law enforcement agency. Over the last few years, the NCA has attempted to reach out to technologically savvy young people in different ways. EGX was the first time it's pitched up to a gaming convention; the NCA said it wanted to educate young people with an interest in computers and suggested that those who mod online games in order to cheat may eventually progress to using low level cybercrime services like DDoS-for-hire and could use steering in the right direction. "The games industry can help us reach young people and educate them on lawful use of cyber skills," Richard Jones, head of the NCA's National Cyber Crime Unit's 'Prevent' team, told Motherboard in an email. "Through attendance at EGX and various other activities, we are seeking to promote ethical hacking or penetration testing, as well as other lawful uses of an interest in computers to young people," Jones said.

Note that holding contradictory beliefs is fairly common of conspiracy theorists (link):

Another study titled Dead and Alive: Beliefs in Contradictory Conspiracy Theories managed to show that, not only will cranks be attracted to and believe in numerous conspiracy theories all at once, but will continue to do so even if the theories in question are completely and utterly incompatible with one another. For instance, the study showed that: "... the more participants believed that Princess Diana faked her own death, the more they believed that she was murdered [and that] ... the more participants believed that Osama Bin Laden was already dead when U.S. special forces raided his compound in Pakistan, the more they believed he is still alive," and that "Hierarchical regression models showed that mutually incompatible conspiracy theories are positively associated because both are associated with the view that the authorities are engaged in a cover-up".

US Panel Extends Nuclear Power Tax Credit (thehill.com) 229

Slashdot reader mdsolar quotes The Hill: The House Ways and Means Committee voted Wednesday to remove a key deadline for a nuclear power plant tax credit... The credit was first enacted in 2005 to spur construction of new nuclear plants, but it has gone completely unused because no new plants have come online since then...

It would likely benefit two reactors under construction at Southern Co.'s Vogtle Electric Generating Plant in Georgia and another two at Virgil C. Summer Nuclear Generating Station in South Carolina. Both projects are at risk of missing the 2020 deadline... "When Congress passed the 2005 act, it could not have contemplated the effort it would take to get a nuclear plant designed and licensed," said representative Tom Rice (R-S.C.).

Although one Democrat criticized the extension by arguing that nuclear power "does better in a socialist economy than in a capitalist one, because nuclear energy prefers to have the public do the cleanup, do the insurance, cover all of the losses and it only wants the profits."

The Verge's Deputy Editor Chris Ziegler Was Secretly Working For Apple For Two Months (gizmodo.com) 78

An anonymous reader quotes a report from Gizmodo: Late this afternoon, Nilay Patel, the editor-in-chief of The Verge, published a post detailing the circumstances around the departure of Chris Ziegler, a founding member of the site. As it turns out, according to Patel, Ziegler had been pulling double duty as an employee of both The Verge and Apple. "The circumstances of Chris' departure from The Verge raised ethical issues which are worth disclosing in the interests of transparency and respect for our audience," Patel wrote. "We're confident that there wasn't any material impact on our journalism from these issues, but they are still serious enough to merit disclosure." According to Patel, Ziegler, whose most recent post was published in July, began working for Apple in July but didn't disclose his new job; The Verge apparently didn't discover he'd been working there until early September. Patel noted that Ziegler continued to work for The Verge in July, but "was not in contact with us through most of August and into September." What's not clear is how The Verge leadership went six weeks without hearing from their deputy editor or taking serious action (like filing a missing person's report) to try to find him. Patel says they "made every effort to contact him and to offer him help if needed." Patel noted the obvious conflict of interest, and added that Ziegler was fired the same day they verified his employment at Apple. "Chris did not attempt to steer any coverage towards or away from Apple, and any particular decisions he helped make had the same outcomes they would have had absent his involvement," Patel wrote. However, it's still unclear how exactly the team at Vox Media, The Verge's parent company, ascertained there was no editorial consequences from the dual-employment. You can read Patel's full statement here. Vox Media's Fay Sliger followed up with a statement to Gizmodo: "Chris is no longer an employee of The Verge or Vox Media. Chris accepted a position with Apple, stopped communicating with The Verge's leadership, and his employment at The Verge was terminated. Vox Media's editorial director Lockhart Steele conducted an internal review of this conflict of interest, and after a thorough investigation, it was determined that there was no impact on editorial decisions or journalism produced at The Verge or elsewhere in Vox Media. We've shared details about this situation with The Verge's audience and will continue to be transparent should any new information come to light."

Cops Are Raiding Homes of Innocent People Based Only On IP Addresses (fusion.net) 240

Kashmir Hill has a fascinating story today on what can go wrong when you solely rely on IP address in a crime investigation -- also highlighting how often police resort to IP addresses. In the story she follows a crime investigation that led police to raid a couple's house at 6am in the morning, because their IP address had been associated with the publication of child porn on notorious 4chan porn. The problem was, Hill writes: the couple -- David Robinson and Jan Bultmann -- weren't the ones who had uploaded the child porn. All they did was voluntarily use one of their old laptops as a Tor exit relay, a software used by activists, dissidents, privacy enthusiasts as well as criminals, so that people who want to stay anonymous when surfing the web could do so. Hill writes: Robinson and Bultmann had [...] specifically operated the riskiest node in the chain: the exit relay which provides the IP address ultimately associated with a user's activity. In this case, someone used Tor to make the porn post, and his or her traffic had been routed through the computer in Robinson and Bultmann's house. The couple wasn't pleased to have helped someone post child porn to the internet, but that's the thing about privacy-protective tools: They're going to be used for good and bad purposes, and to support one, you might have to support the other.Robinson added that he was a little let down because police didn't bother to look at the public list which details the IP addresses associated with Tor exit relays. Hill adds: The police asked Robinson to unlock one MacBook Air, and then seemed satisfied these weren't the criminals they were looking for and left. But months later, the case remains open with Robinson and Bultmann's names on police documents linking them to child pornography. "I haven't run an exit relay since. The police told me they'd be back if it happened again," Robinson said; he's still running a Tor node, just not the end point anymore. "I have to take the threat seriously because I don't want my wife or I to wake up with guns in our faces."Technologist Seth Schoen, and EFF Executive Director Cindy Cohn in a white paper aimed at courts and cops. "For many reasons, connecting an individual to a crime linked to an IP address, without any additional investigation, is irresponsible and threatens the civil liberties of innocent people."

At Least 26 Claimed Galaxy Note 7 Fire Reports Were Untrue, Samsung Says (zdnet.com) 106

Lately, a lot of behind the scene conversations have been suggesting that perhaps the Note 7 battery explosion fiasco has been blown out of the proportion. There's no evidence of any of that, so we won't discuss it any further, but amid all of this, Samsung has confirmed that at least 26 explosion reports that circulated everywhere were hoaxes. From a ZDNet report:Out of the 26 reports, the South Korean tech giant said that in 12 cases they found no fault with the devices. In seven cases, the reported victim could not be reached and in another seven incidents, the consumer cancelled the report or alleged that they threw away the device. In the US, where 1 million devices were recalled, nine such cases were reported. There were three in South Korea, two in France, and one each from the UK, Canada, Singapore, Philippines, Turkey, Vietnam, Croatia, Romania, Iraq, Lebanon, the UAE, and Czech Republic. In Korea, a worker at a convenience store alleged online that their phone exploded but Samsung said the person was currently unreachable. The user in Canada used a picture they found of the Note 7 catching fire and posed it as their own, the company said, and in Singapore, a user claimed they threw the handset out of their car when it caught fire but could not show proof.Makes you think doesn't it?

iPhone 7 Plus Makes Hissing Sound Under Load, Some Users Complain (businessinsider.com) 196

Several commendable users are complaining that their iPhone 7 Plus handsets are making a "hissing" noise especially when they do some heavy weight work. Some users note that this issue extends to the iPhone 7 as well. BusinessInsider reports:Stephen Hackett, cofounder of podcast network Relay FM, tweeted that his iPhone 7 Plus "makes terrible noises when under load," and shared an audio clip of the noise. TechCrunch writer (and former Apple employee) Darrell Etherington responded that his "brand new, just-unboxed [device is] doing the same thing right now." It sounds like the problem isn't affecting all devices, and it's not immediately clear what's behind it. Hackett said on Twitter that Apple will be replacing his device with a new one, which suggests it's a defect rather than just an unexpected quirk of the new smartphone's design. There's some speculation out there as to what's causing it - but nothing concrete yet. Engadget's Jon Fingas suggests it could be "coil whine," a process where electronics make an unintended noise while working, for example.

Robot Snatches Rifle From Barricaded Suspect, Ends Standoff (latimes.com) 129

Slashdot reader schwit1 quotes the L.A. Times: An hours-long standoff in the darkness of the high desert came to a novel end when Los Angeles County sheriff's deputies used a robot to stealthily snatch a rifle from an attempted murder suspect, authorities said Thursday. Officials said the use of the robot to disarm a violent suspect was unprecedented for the Sheriff's Department, and comes as law enforcement agencies increasingly rely on military-grade technology to reduce the risk of injury during confrontations with civilians.

"The robot was a game changer here," said Capt. Jack Ewell, a tactical expert with the Sheriff's Department -- the largest sheriff's department in the nation. "We didn't have to risk a deputy's life to disarm a very violent man."

It was only later when the robot came back to also pull down a wire barricade that the 51-year-old suspect realized his gun was gone.

Right To Be Forgotten? Web Privacy Debate in Italy After Women's Suicide (ndtv.com) 424

The suicide of a woman who battled for months to have a video of her having sex removed from the internet is fuelling debate in Italy on the "right to be forgotten" online. The 31-year-old, identified as Tiziana, was found hanged at her aunt's home in Mugnano, close to Naples in the country's south on Tuesday, reports Agence France-Presse. From the report: Her death came a year after she sent a video of herself having sex to some friends, including her ex-boyfriend, to make him jealous. The video and her name soon found their way to the web and went viral, fuelling mockery of the woman online. The footage has been viewed by almost a million internet users. In a bid to escape the humiliation, Tiziana quit her job, moved to Tuscany and tried to change her name, but her nightmare went on. The words "You're filming? Bravo," spoken by the woman to her lover in the video, have become a derisive joke online, and the phrase has been printed on T-shirts, smartphone cases and other items. After a long court battle, Tiziana recently won a "right to be forgotten" ruling ordering the video to be removed from various sites and search engines, including Facebook.

Jeff Bezos Unveils the Design of Blue Origin's Future Orbital Rocket -- New Glenn (theverge.com) 79

Earlier this year, Jeff Bezos, the founder of Blue Origin said he would unveil details about his company's orbital rocket sometime "later this year." He is now delivering on the promise. Bezos has released some preliminary details about the "New Glenn" rocket which employs seven of the company's new generation BE-4 rocket engines. The rocket, named after the first American to reach orbit, is bigger than Elon Musk's Falcon Heavy rocket. Bezos said he intends to launch the New Glenn in less than a decade from now. The Verge reports: The New Glenn will incorporate reusability, according to an email update from Bezos. The first stage of the rocket will be able to land post-launch, similar to how Blue Origin's New Shepard vehicle lands after a flight. However, the New Shepard is only capable of going to sub-orbital space, so it's not traveling as fast or as high as a rocket going to orbit. Landing an orbital rocket post-launch will put Blue Origin in a whole new ball game. And it looks like there will be a lot of rocket to land. The New Glenn will be 23 feet in diameter and range between 270 and 313 feet high. That height depends on if there is one upper stage or two on top of the rocket. With just one upper stage, the rocket will be able to send satellites and people into lower Earth orbit (LEO). But with two upper stages, the New Glenn is capable of taking payloads beyond LEO. The main portion of the rocket will be powered by seven BE-4s, an engine that Blue Origin is currently developing. It's the same engine that the company hopes to sell to the United Launch Alliance to power the future Vulcan rocket. Combined, the BE-4s should provide 3.85 million pounds of thrust, according to Bezos. That's more thrust than the 2 million pounds the Delta IV Heavy is capable of, and slightly less than the 5 million pounds SpaceX's Falcon Heavy can pull off.Bezos said: Our vision is millions of people living and working in space, and New Glenn is a very important step. It won't be the last of course. Up next on our drawing board: New Armstrong. But that's a story for the future.

I've been at a poorly-run community college where assignments for teachers were made, maybe, 3 days before class started. I fear that's semi-common. Current school is much better, and of course, I've never seen any FBI raids.

To my understanding, one of the points of debate was that this was an administrative finance-tracking scandal, and at no point were any aspersions being placed on the teachers or quality of education coming out of CCSF. At least that's what I got from the local public protests over the threat of loss of accreditation; the local populace was very happy with CCSF and its effects as students.

“The actions of the ACCJC –- an organization accountable to no one — have unnecessarily put at risk the livelihoods of the nearly 2,500 hard-working men and women at the college,” Tim Paulson of the San Francisco Central Labor Council said in a statement. “What’s more, their move to deny CCSF accreditation has imperiled the future of San Francisco’s working people, who rely heavily on a CCSF education for workforce training, language learning, and a pathway to better futures for themselves and their communities.”
