Quantum particles have a unique ability to travel in the opposite direction from their momentum. Or, as slew (Slashdot reader #2,918) puts it, "When pushed, quantum particles can fight back." slew writes:
Who knew quantum particles were passive aggressive? It's subtle, but researchers "have shown that 'backflow' can always occur, even if a force is acting on the quantum particle while it travels. The backflow effect is the result of wave-particle duality and the probabilistic nature of quantum mechanics..."
Dr Daniela Cadamuro, Researcher at the Technical University of Munich, said "The backflow effect in quantum mechanics has been known for quite a while, but it has always been discussed in regards to 'free' quantum particles, i.e., no external forces are acting on the particle."Read Replies (0)

Kevin Poulsen writes on the Daily Beast:
It turns out Microsoft has something even more formidable than Moscow's malware: Lawyers. Last year attorneys for the software maker quietly sued the hacker group known as Fancy Bear in a federal court outside Washington DC, accusing it of computer intrusion, cybersquatting, and infringing on Microsoft's trademarks... Since August, Microsoft has used the lawsuit to wrest control of 70 different command-and-control points from Fancy Bear... Rather than getting physical custody of the servers, which Fancy Bear rents from data centers around the world, Microsoft has been taking over the Internet domain names that route to them. These are addresses like "livemicrosoft[.]net" or "rsshotmail[.]com" that Fancy Bear registers under aliases for about $10 each. Once under Microsoft's control, the domains get redirected from Russia's servers to the company's, cutting off the hackers from their victims, and giving Microsoft a omniscient view of that servers' network of automated spies.
"In other words," Microsoft outside counsel Sten Jenson explained in a court filing last year, "any time an infected computer attempts to contact a command-and-control server through one of the domains, it will instead be connected to a Microsoft-controlled, secure server."Read Replies (0)

An anonymous reader quotes IEEE Spectrum's annual report on the top programming languages:
As with all attempts to rank the usage of different languages, we have to rely on various proxies for popularity. In our case, this means having data journalist Nick Diakopoulos mine and combine 12 metrics from 10 carefully chosen online sources to rank 48 languages. But where we really differ from other rankings is that our interactive allows you choose how those metrics are weighted when they are combined, letting you personalize the rankings to your needs. We have a few preset weightings -- a default setting that's designed with the typical Spectrum reader in mind, as well as settings that emphasize emerging languages, what employers are looking for, and what's hot in open source...
Python has continued its upward trajectory from last year and jumped two places to the No. 1 slot, though the top four -- Python, C, Java, and C++ -- all remain very close in popularity. Indeed, in Diakopoulos's analysis of what the underlying metrics have to say about the languages currently in demand by recruiting companies, C comes out ahead of Python by a good margin... Ruby has fallen all the way down to 12th position, but in doing so it has given Apple's Swift the chance to join Google's Go in the Top Ten... Outside the Top Ten, Apple's Objective-C mirrors the ascent of Swift, dropping down to 26th place. However, for the second year in a row, no new languages have entered the rankings. We seem to have entered a period of consolidation in coding as programmers digest the tools created to cater to the explosion of cloud, mobile, and big data applications.
"Speaking of stabilized programming tools and languages," the article concludes, "it's worth noting Fortran's continued presence right in the middle of the rankings (sitting still in 28th place), along with Lisp in 35th place and Cobol hanging in at 40th."Read Replies (0)

Ina Fried, reporting for Axios: Shares of Microsoft hit record territory in after-hours trading on Thursday, topping $75 a share, after the software giant's better-than-expected financial results. As has been the case for the last several quarters, strength in Microsoft's cloud business, including Office 365 and Windows Azure, was the key to the company's growth. Of note, Microsoft CFO Amy Hood told analysts that, for the first time, Microsoft got more revenue from Office 365 subscriptions than from traditional Office software licensing. Why it matters: Microsoft has shown an ability to grow its business even as the PC market has stalled, reflecting moves the company made in the cloud both since Satya Nadella took over as CEO as well as some that were in place before he took over the top spot.Read Replies (0)

From a report: 'Guardians of the Galaxy,' 'Avengers: Age of Ultron' and 'Beauty and the Beast' are now under the microscope for use of facial capture technology. Upping the stakes over a technology called "performance motion capture," Rearden LLC is going after The Walt Disney Company in a lawsuit filed this week. The plaintiff, a firm incubated by Silicon Valley entrepreneur Steve Perlman, is demanding an injunction prohibiting Disney from distributing Guardians of the Galaxy, Avengers: Age of Ultron and Beauty and the Beast. The new lawsuit comes a year after Rearden scored a startling injunction against two Chinese firms that purchased allegedly stolen technology known as MOVA, which was being licensed by Digital Domain 3.0. At the time, some legal observers were reading the ruling as notice to Hollywood studios that the facial motion capture technology was out of play. According to Rearden's latest lawsuit in California federal court, Disney didn't listen. "Disney used the stolen MOVA Contour systems and methods, made derivative works, and reproduced, distributed, performed, and displayed at least Guardians of the Galaxy, Avengers: Age of Ultron, and Beauty and the Beast, in knowing or willfully blind violation of Rearden Mova LLC's intellectual property rights."Read Replies (0)

An anonymous reader quotes a report from Reuters: As part of its review of Amazon's agreement to buy Whole Foods, the Federal Trade Commission is looking into allegations that Amazon misleads customers about its pricing discounts, according to a source close to the probe. The FTC is probing a complaint brought by the advocacy group Consumer Watchdog, which looked at some 1,000 products on Amazon's website in June and found that Amazon put reference prices, or list prices, on about 46 percent of them. An analysis found that in 61 percent of products with reference prices, Amazon's reference prices were higher than it had sold the same product in the previous 90 days, Consumer Watchdog said in a letter to the FTC dated July 6. Amazon said in a statement that Consumer Watchdog's study was "deeply flawed." "The conclusions the Consumer Watchdog group reached are flat out wrong," Amazon said. "We validate the reference prices provided by manufacturers, vendors and sellers against actual prices recently found across Amazon and other retailers."Read Replies (0)

An anonymous reader quotes a report from Ars Technica: Sony appears to be using copyright law in an attempt to remove all traces of a leaked PlayStation 4 Software Development Kit (PS4 SDK) from the Web. That effort also seems to have extended in recent days to the forced removal of the mere discussion of the leak and the posting of a separate open source, homebrew SDK designed to be used on jailbroken systems. The story began a few weeks ago, when word first hit that version 4.5 of the PS4 SDK had been leaked online by a hacker going by the handle Kromemods. These SDKs are usually provided only to authorized PS4 developers inside development kits. The SDKs contain significant documentation that, once made public, can aid hackers in figuring out how to jailbreak consoles, create and install homebrew software, and enable other activities usually prohibited by the hardware maker (as we've seen in the wake of previous leaks of PlayStation 3 SDKs). While you can still find reference to the version 4.5 SDK leak on places like Reddit and MaxConsole, threads discussing and linking to those leaked files on sites like GBATemp and PSXhax, for example, appear to have been removed after the fact. Cached versions of those pages show links (now defunct) to download those leaked files, along with a message from KromeMods to "Please spread this as much as possible since links will be taken down... We will get nowhere if everything keeps private; money isn't everything." KromeMods notes on Twitter that his original tweet posting a link to the leaked files was also hit with a copyright notice from Sony.Read Replies (0)
