Are processors pushing up against the limits of physics?

When I first started reading Ars Technica, performance of a processor was measured in megahertz, and the major manufacturers were rushing to squeeze as many of them as possible into their latest silicon. Shortly thereafter, however, the energy needs and heat output of these beasts brought that race crashing to a halt . More recently, the number of processing cores rapidly scaled up, but they quickly reached the point of diminishing returns. Now, getting the most processing power for each Watt seems to be the key measure of performance. None of these things happened because the companies making processors ran up against hard physical limits. Rather, computing power ended up being constrained because progress in certain areas—primarily energy efficiency—was slow compared to progress in others, such as feature size. But could we be approaching physical limits in processing power? In this week’s edition of Nature , The University of Michigan’s Igor Markov takes a look at the sorts of limits we might face. Clearing hurdles Markov notes that, based on purely physical limitations, some academics have estimated that Moore’s law had hundreds of years left in it. In contrast, the International Technology Roadmap for Semiconductors (ITRS), a group sponsored by the major semiconductor manufacturing nations, gives it a couple of decades. And the ITRS can be optimistic; it once expected that we would have 10GHz CPUs back in the Core2 days. The reason for this discrepancy is that a lot of hard physical limits never come into play.

Internet routers hitting 512K limit, some become unreliable

Chart courtesy of Renesys, a subsidiary of Dyn From performance issues at hosting provider Liquid Web to outages at eBay and LastPass, large networks and websites suffered a series of disruptions and outages on Tuesday. Some Internet engineers are blaming the disruptions on a novel technical issue that impacts older Internet routers. At the heart of the issue, the growth of routable networks on the Internet overwhelmed the amount of memory set aside in infrastructure hardware, typically routers and switches, that determines the appropriate way to route data through the Internet. For the first time, the lists of routable networks—also called border gateway protocol (BGP) tables—surpassed a significant power of two (two to the 19th power or 512K). Many older routers limit their use of a specialized, and expensive, type of memory known as ternary content-addressable memory (TCAM) to 512K by default. When the tables outgrew the space allotted for them, the routers shut down or slowed. Read 10 remaining paragraphs | Comments

Xbox One to get far better at playing pirated TV shows

The Xbox One Digital TV Tuner. Microsoft The Xbox 360 and PlayStation 3 aren’t just games consoles; a succession of software updates has made them into rich media boxes, capable of playing all manner of video and audio on your TV. The Xbox One and PlayStation 4, by contrast, have thus far offered a rather sad and limited media experience. On the Xbox One, at least, that experience is about to get a whole lot better, as Microsoft revealed today at Gamescom in Germany. A new media player app for the console is being released with support for playback from USB devices and, later in the year, DLNA streaming from other devices on the home network, including Windows PCs. This is in addition to its existing ability to have content pushed by network devices. On its own, this would merely bring the Xbox One’s media capabilities up to the same level as those found in the older Xbox 360, but Microsoft is going a step further with substantially wider format support. The company has published a full list  of supported codecs, but one stands out: support for MKV containers. While MKV is a rarity in the world of explicitly authorized video, it’s quite abundant in the murky world of pirated TV shows. Native MKV support will make watching this content substantially easier on the Xbox One. Read 6 remaining paragraphs | Comments

Lyft: Uber scheduled, canceled 5,000 rides to hassle us

The Uber smartphone app. Uber CNN reports that people associated with car-on-demand service Uber have been attempting to sabotage an Uber competitor, Lyft, by ordering and canceling as many as 5,000 rides since October 2013. Lyft drivers have also complained that Uber employees will call them to take “short, low-profit rides largely devoted to luring them to work for Uber.” Uber reportedly used the ride request-and-cancellation tactic earlier this year on another competitor, Gett, to the tune of around 100 rides. Those ride calls were placed by employees as high in the company as Uber’s New York general manager, Josh Mohrer. The calls serve a number of purposes: frustrating drivers, wasting their time and gas approaching a fare that won’t come through, and occupying them to artificially limit driver availability, if only temporarily. Lyft claims to have sussed out the fake requests using phone numbers used by “known Uber recruiters.” Lyft claims that one Uber recruiter requested and canceled 300 rides from May 26 to June 10, and it said that recruiter’s phone number was associated with 21 more accounts with 1,524 canceled rides between them. However, in this instance, there’s no evidence that the cancellations were suggested by Uber corporate, according to CNN. Read 2 remaining paragraphs | Comments

Researchers design flat sheet that can fold itself into a robot, walk away

Seth Kroll, Wyss Institute As if a brain-like processing chip weren’t bad enough news for us humans, this week’s edition of Science also describes a robot that, after being laid out as a flat sheet, can fold itself into the appropriate shape to take its on-board electronics for a walk. Why would we possibly want self-assembling, flat-packed electronics of this kind? The authors of the Science paper, who are part of a Harvard/MIT collaboration, offer two reasons. First, it’s much easier to assemble something as a planar surface. With the right layers in place, it’s simple to cut them into the appropriate shapes and then embed the electronics where they’re needed, since there’s no awkward internal spaces to deal with. The second reason is that it’s easy to transport things when they’re shaped like a sheet. Since the devices can assemble themselves, they can be shipped to any destination and used without any hassle or high-level technical knowledge. Of course, having a good idea and actually knowing how to create a self-assembling device are two different things. Fortunately, the ability to construct elaborate three-dimensional items from a flat sheet is a solved problem, thanks to origami. Software like  Origamizer  can even determine how to cut and fold a sheet in order to produce a specified three-dimensional structure. Read 8 remaining paragraphs | Comments

Netflix surpasses HBO in subscriber revenue

Reed Hastings’ Facebook update boasting about Netflix’s (possibly temporary) victory over its unwilling adversary. Netflix has surpassed HBO in subscriber revenue, according to a status update from Netflix CEO Reed Hastings on Wednesday. The company is now pulling in $1.146 billion compared to HBO’s $1.141 billion, and it boasts  50.05 million subscribers , according to its second-quarter earnings reported in July. Netflix has long seen HBO as a competitor in terms of audience and, more recently, in produced content. While HBO has slowly started to come down from the ivory cable tower and be more flexible about how it offers its subscriptions, Netflix has been making gains. Hastings acknowledged that HBO still surpasses Netflix “in profits and Emmy’s [sic], but we are making progress.” Hastings has said many times before that he considers HBO to be a media company that is well-positioned in the changing distribution landscape, where power is shifting away from cable providers and toward Internet streaming.

Internet Explorer to start blocking old Java plugins

This month’s Patch Tuesday update for Internet Explorer will include a new feature: it will block out-of-date ActiveX controls. More specifically, it will block out-of-date versions of the Java plugin. Although Microsoft is describing the feature as an ActiveX block, the list of prohibited plugins is currently Java-centric. Stale versions of Flash and Silverlight will be able to stick around, at least for now, though Microsoft says that other out-of-date ActiveX controls will be added to the block list later. Old, buggy versions of the Java plugin have long been used as an exploit vector, with Microsoft’s own security report fingering Java in 84.6 to 98.5 percent of detected exploit kits (bundles of malware sold commercially). Blocking obsolete Java plugins should therefore go a long way toward securing end-user systems. Read 1 remaining paragraphs | Comments

Re/code: Apple’s next iPhone event happens on September 9

This iPhone 5S is likely to be superseded in September. Andrew Cunningham After a summer full of rumors and part leaks, Re/code reports that Apple is planning to hold its next iPhone event on Tuesday, September 9. Re/code co-founder Walt Mossberg has a long history with Apple and his prior publication AllThingsD correctly predicted the dates Apple’s iPhone and iPad events last year, so there’s a good chance this is the real thing. This year Apple is widely expected to release a redesigned “iPhone 6” with a larger screen. Reports have varied, but anonymous sources have told multiple publications that the company is planning a 4.7-inch phone to rival “normal” handsets from competitors, as well as a 5.5-inch version intended to compete with so-called “phablet” phones like Samsung’s Galaxy Note series. Last year’s top-end iPhone 5S and midrange iPhone 5C were both refinements of the iPhone 5 design introduced in 2012 . Apple also uses its iPhone events to announce final release dates for new iOS versions, which have for the past two years have come out on the second Wednesday after the iPhone unveiling. This means a final release of iOS 8 is likely on or near September 17, assuming Apple doesn’t change its plans. iOS 8 will refine the new design introduced in iOS 7 , allow iOS devices to work more closely with Macs running OS X Yosemite, and introduce a number of under-the-hood improvements including Extensions. Third-generation Apple TVs will receive an updated UI, as well. Read 1 remaining paragraphs | Comments

Mount your hard drive… on your RAM?

A weird place for an SSD. Apacer PC makers do all kinds of things to save space inside their cases, but this is a new one to us: Apacer  is apparently sampling sticks of DDR3 desktop RAM that include slots for M.2 SSD add-in boards and CFast  CompactFlash cards, allowing you to mount storage devices directly to your RAM rather than using slots on the motherboard. The slots will still use the SATA III interface to transfer data—they’re just mounted to the RAM and they draw power through the RAM slot. These sticks will support all three lengths of M.2 SSD boards (2242, 2260, and 2280). That’s especially useful because, as AnandTech points out , only one mini-ITX desktop motherboard can directly support full-length M.2 boards. Full-length M.2 boards are necessary to accommodate higher storage capacities—currently available drives top out at 512GB, but 1TB drives are on the horizon . Connectors visible on top of the DIMMs would likely need to be connected to the SATA connectors on your motherboard; unfortunately it doesn’t look like these can take advantage of the faster PCI-Express flavor of M.2.

What we judge when we judge freemium, and the money we’ve spent on Hearthstone

BagoGames Few people know what to make of the Kim Kardashian: Hollywood mobile game. By reputation it’s boring, vapid, materialistic, and shallow—according to many serious gamers—and is deplorable not least because players can spend money to get ahead. The wails only grew louder when reports indicated that the game earned $1.6 million in its first five days and is on track to make $200 million in annual revenue , according to one analyst. While many gamers and gaming journalists struggled to figure out why anyone would spend money on a game made by and featuring a reality TV star, we aren’t totally in the dark. For one, casting shade on the subject matter is a value judgment of a certain set of interests and lifestyle. And on a meta level,  how people use their leisure time . Let he who has lived every moment deliberately immersed in deep consideration of the universe cast the first Angry Bird. Materialism in games probably does not cause materialism in the streets . For another, Kim K is actually pretty self-aware of its own materialism and glorification of social climbing and has a sense of irony about the world it gives players to try and thrive in. To wit, one of the things you can spend in-game money on is new body parts. Read 25 remaining paragraphs | Comments
