How Facebook Is Saving Power By 10-15% Through Better Load Balancing

An anonymous reader writes Facebook today revealed details about Autoscale, a system for power-efficient load balancing that has been rolled out to production clusters in its data centers. The company says it has “demonstrated significant energy savings.” or those who don’t know, load balancing refers to distributing workloads across multiple computing resources, in this case servers. The goal is to optimize resource use, which can mean different things depending on the task at hand. Read more of this story at Slashdot.

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

Stacking solar cells leads to more efficient energy collection, lower bills

Thanks to the efforts of a North Carolina-based company, solar panels are about to get a lot more efficient. Semprius produces the collection devices by stacking materials on top of each other in order to catch more frequencies of light. In the process, cell stacking boosted efficiency to around 45 percent during tests. The new tech can be produced quickly using cells that are one millimeter across to reduce cooling needs while combining semiconductor materials and reusing the components cells are grown on. All of that will help Semprius achieve 50 percent efficiency in the next three to five years — up from the current 25 percent range. Unfortunately, the new method will be quite expensive until demand warrants mass production. However, more efficient collection will lead to lower overall cost in the long run, and make solar power as cheap as that produced by natural gas facilities.

Network Hijacker Steals $83,000 In Bitcoin

An anonymous reader writes with news that bogus BGP announcements can be used to hijack work done by cryptocurrency mining pools. Quoting El Reg: Researchers at Dell’s SecureWorks Counter Threat Unit (CTU) have identified an exploit that can be used to steal cryptocurrency from mining pools — and they claim that at least one unknown miscreant has already used the technique to pilfer tens of thousands of dollars in digital cash. The heist was achieved by using bogus Border Gateway Protocol (BGP) broadcasts to hijack networks belonging to multiple large hosting companies, including Amazon, Digital Ocean, and OVH, among others. After sending the fake BGP updates miners unknowingly contributed work to the attackers’ pools. Read more of this story at Slashdot.

Cornering the Market On Zero-Day Exploits

Nicola Hahn (1482985) writes Kim Zetter of Wired Magazine has recently covered Dan Greer’s keynote speech at Black Hat USA. In his lengthy address Greer, representing the CIA’s venture funding arm, suggested that one way that the United States government could improve cyber security would be to use its unparalleled budget to buy up all the underground’s zero-day vulnerabilities. While this would no doubt make zero-day vendors like VUPEN and middlemen like the Grugq very wealthy, is this strategy really a good idea? Can the public really trust the NSA to do the right thing with all those zero-day exploits? Furthermore, recall the financial meltdown of 2008 where the public paid the bill for Wall Street’s greed. If the government pays for information on all these unpatched bugs would society simply be socializing the cost of hi-tech’s sloppy engineering? Whose interests does this “corner-the-market” approach actually serve? Read more of this story at Slashdot.

J. Michael Straczynski wants to reboot Babylon 5 as a big-budget movie

Warner Bros. According to a report from TV Wise , Babylon 5 showrunner J. Michael Straczynski will shortly begin work on a rebooted big-screen version of his 1990s sci-fi TV series. Straczynski made the announcement at San Diego Comic-Con last week. Babylon 5’s pilot episode originally aired in 1993, with the series beginning its regular run almost a year later as a foundational component of the now-defunct Prime Time Entertainment Network . The show lacked the production budget of its contemporary rival Star Trek: Deep Space 9 (which allegedly lifted some or all of its core concepts directly from Straczynski’s original—and rejected— Babylon 5 pitch meeting with Paramount). Still, it attracted enough of an audience to accomplish a noteworthy feat: Babylon 5 became the only non- Star Trek science fiction show on American television to reach its series completion without being cancelled. Not until 2004’s Battlestar Galactica reboot would another non- Star Trek show earn the same distinction. After Babylon 5 ended in 1998, Straczynski (usually referred to simply by his initials, “JMS”) tried multiple times to bring a B5 movie to theaters. The most recent attempt in 2004 came the closest, with a completed script and some preproduction work underway, but without financial backing from Warner Bros. the project had to be abandoned .

American sitcoms with all jokes removed

You would think that, if you take out all the jokes and leave just the plot in American sitcoms, you would end up with something that is not funny at all. And you would be completely right—although the edits of Seinfeld and Curb Your Enthusiasm still had some solid funny moments. Read more…

Microsoft’s First Website From 1994 Looks Delightfully Ancient Today

In 1994, there were just a few thousand websites on the internet. HTML was still new, and the concept of web publishing was still embryonic. It was the year that Microsoft launched its own website—and today, to celebrate its 20th anniversary on the web, it dug it up and put it back online . Read more…

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.
