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.

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.

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."

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."

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."
