Massive Exoplanet Evolved In Extreme 4-Star System 48

Posted by samzenpus from the four-is-better-than-one dept.
astroengine writes "For only the second time, an exoplanet living with an expansive family of four stars has been revealed. The exoplanet, which is a huge gaseous world 10 times the mass of Jupiter, was previously known to occupy a 3-star system, but a fourth star (a red dwarf) has now been found, revealing quadruple star systems possessing planets are more common than we thought. "About four percent of solar-type stars are in quadruple systems, which is up from previous estimates because observational techniques are steadily improving," said co-author Andrei Tokovinin of the Cerro Tololo Inter-American Observatory in Chile. The whole 4-star family is collectively known as 30 Ari, located some 136 light-years from Earth — in our interstellar backyard. The exoplanet orbits the primary star of the system once every 335 days. The primary star has a new-found binary partner (which the exoplanet does not orbit) and this pair are locked in an orbital dance with a secondary binary, separated by a distance of 1,670 astronomical unit (AU), where 1 AU is the average distance between the Earth and sun.

One Year Later, We're No Closer To Finding MtGox's Missing Millions 178

Posted by Soulskill from the crime-pays dept.
itwbennett writes: When Mt. Gox collapsed on Feb. 28, 2014, with liabilities of some ¥6.5 billion ($63.6 million), it said it was unable to account for some 850,000 bitcoins. Some 200,000 of them turned up in an old-format bitcoin wallet last March, bringing the tally of missing bitcoins to 650,000 (now worth about $180 million). In January, Japan's Yomiuri Shimbun newspaper, citing sources close to a Tokyo police probe of the MtGox collapse, reported that only 7,000 of the coins appear to have been taken by hackers, with the remainder stolen through a series of fraudulent transactions. But there's still no explanation of what happened to them, and no clear record of what happened on the exchange.

Linux 4.0 Getting No-Reboot Patching 125

Posted by Soulskill from the post-your-uptimes dept.
An anonymous reader writes: ZDNet reports that the latest changes to the Linux kernel include the ability to apply patches without requiring a reboot. From the article: "Red Hat and SUSE both started working on their own purely open-source means of giving Linux the ability to keep running even while critical patches were being installed. Red Hat's program was named kpatch, while SUSE' is named kGraft. ... At the Linux Plumbers Conference in October 2014, the two groups got together and started work on a way to patch Linux without rebooting that combines the best of both programs. Essentially, what they ended up doing was putting both kpatch and kGraft in the 4.0 Linux kernel." Note: "Simply having the code in there is just the start. Your Linux distribution will have to support it with patches that can make use of it."

Schneier: Either Everyone Is Cyber-secure Or No One Is 130

Posted by Soulskill from the nobody's-safe-except-the-amish dept.
Presto Vivace sends a new essay from Bruce Schneier called "The Democratization of Cyberattack." Quoting: When I was working with the Guardian on the Snowden documents, the one top-secret program the NSA desperately did not want us to expose was QUANTUM. This is the NSA's program for what is called packet injection--basically, a technology that allows the agency to hack into computers.Turns out, though, that the NSA was not alone in its use of this technology. The Chinese government uses packet injection to attack computers. The cyberweapons manufacturer Hacking Team sells packet injection technology to any government willing to pay for it. Criminals use it. And there are hacker tools that give the capability to individuals as well. ... We can't choose a world where the U.S. gets to spy but China doesn't, or even a world where governments get to spy and criminals don't. We need to choose, as a matter of policy, communications systems that are secure for all users, or ones that are vulnerable to all attackers. It's security or surveillance.

Rosetta Photographs Its Own Shadow On Comet 67P/C-G 21

Posted by Soulskill from the pretty-pictures dept.
mpicpp notes an image release from the European Space Agency showing the shadow of its Rosetta probe on the comet it's currently orbiting. The probe snapped the picture from a very low flyby — only six kilometers off the surface. The image has a resolution of 11cm/pixel. The shadow is fuzzy and somewhat larger than Rosetta itself, measuring approximately 20 x 50 metres. If the Sun were a point source, the shadow would be sharp and almost exactly the same size as Rosetta (approximately 2 x 32 m). However, even at 347 million km from 67P/C-G on 14 February, the Sun appeared as a disc about 0.2 degrees across (about 2.3 times smaller than on Earth), resulting in a fuzzy “penumbra” around the spacecraft’s shadow on the surface. In this scenario and with Rosetta 6 km above the surface, the penumbra effect adds roughly 20 metres to the spacecraft’s dimensions, and which is cast onto the tilted surface of the comet.

Study: Refactoring Doesn't Improve Code Quality 247

Posted by Soulskill from the just-makes-you-hate-it-a-bit-less dept.
itwbennett writes: A team of researchers in Sri Lanka set out to test whether common refactoring techniques resulted in measurable improvements in software quality, both externally (e.g., Is the code more maintainable?) and internally (e.g., Number of lines of code). Here's the short version of their findings: Refactoring doesn't make code easier to analyze or change (PDF); it doesn't make code run faster; and it doesn't result in lower resource utilization. But it may make code more maintainable.

Deutsche Telecom Calls For Google and Facebook To Be Regulated Like Telcos 106

Posted by timothy from the oh-definitely-trust-the-government dept.
An anonymous reader writes Tim Hoettges, the CEO of the world's third-largest telecoms company, has called for Google and Facebook to be regulated in the same way that telcos are, declaring that "There is a convergence between over-the-top web companies and classic telcos" and "We need one level regulatory environment for us all." The Deutsche Telekom chief was speaking at Monday's Mobile World Congress, and further argued for a loosening of the current regulations which telcos operate under, in order to provide the infrastructure development that governments and policy bodies are asking of them. Hoettges' imprecation comes in the light of news about the latest Google Dance — an annual change in ranking criteria which boosts some businesses and ruins others. The case for and against regulating Google-level internet entities comes down to one question: who do you trust to 'not be evil'?

If you don't know the full extent of the law you are neither free nor safe.

There's plenty of laws to do with operating vehicles; when you do the theory part of the driving test you learn those. There's plenty of laws to do with dealing in real estate; you'll learn them when training for the job or to pass the necessary certificate.

If you're not in the business of selling houses and just walking down the street then it's simple. Don't punch anyone in the nads, don't take anything that belongs to someone else and don't block other people - stuff you should have learned when you were in kindergarten.

World's First Lagoon Power Plants Unveiled In UK 197

Posted by samzenpus from the power-up dept.
AmiMoJo writes Plans to generate electricity from the world's first series of tidal lagoons have been unveiled in the UK. The six lagoons — four in Wales and one each in Somerset and Cumbria — will capture incoming and outgoing tides behind giant sea walls, and use the weight of the water to power turbines. The series of six lagoons could generate 8% of the UK's electricity for an investment of £12bn. Tidal Lagoon Power wants £168 per MWh hour for electricity in Swansea, reducing to £90-£95 per MWh for power from a second, more efficient lagoon in Cardiff. The £90 figure compares favorably with the £92.50 price for power from the planned Hinkley nuclear station, especially as the lagoon is designed to last 120 years — at a much lower risk than nuclear. Unlike power from the sun and wind, tidal power is predictable. Turbines capture energy from two incoming and two outgoing tides a day, and are expected to be active for an average of 14 hours a day. Friends of the Earth Cymru, said the group is broadly in favor of the Swansea lagoon.

Boko Haram are active in Chad. Chad borders Libya, where ISIS operate. Iran is currently in the way between ISIS and the Taliban, but it's debatable whether that makes things better or worse. It's not like two apparent enemies haven't attacked a third party before.

The world's smaller than you think.
