Study Finds That Astronauts Are Severely Sleep Deprived

sciencehabit (1205606) writes “Researchers tracked the sleep patterns of 85 crew members aboard the International Space Station and space shuttle and found that despite an official flight schedule mandating 8.5 hours of sleep per night, they rarely got more than five. In fact, getting a full night’s rest was so difficult that three-quarters of shuttle mission crew members used sleep medication, and sometimes entire teams were sedated on the same night. Given that sleep deprivation contributes to up to 80% of aviation accidents, it’s important to better understand why sleep is so difficult in space, the authors say.” Read more of this story at Slashdot.

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.

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.

Parallax Completes Open Hardware Vision With Open Source CPU

First time accepted submitter PotatoHead (12771) writes “This is a big win for Open Hardware Proponents! The Parallax Propeller Microcontroller VERILOG code was released today, and it’s complete! Everything you need to run Open Code on an Open CPU design. This matters because you can now build a device that is open hardware, open code all the way down to the CPU level! Either use a product CPU, and have access to it’s source code to understand what and how it does things, or load that CPU onto a suitable FPGA and modify it or combine it with your design.” Read more of this story at Slashdot.

Skype Blocks Customers Using OS-X 10.5.x and Earlier

lurker412 writes Yesterday, and without previous warning, all Mac users running Leopard or earlier versions of OS-X have been locked out of Skype. Those customers are given instructions to update, but following them does not solve the problem. The Skype Community Forum is currently swamped with complaints. A company representative active on the forum said “Unfortunately we don’t currently have a build that OS X Leopard (10.5) users could use” but did not answer the question whether they intend to provide one or not.

Facebook Seeks Devs To Make Linux Network Stack As Good As FreeBSD’s

An anonymous reader writes Facebook posted a career application which, in their own words is ‘seeking a Linux Kernel Software Engineer to join our Kernel team, with a primary focus on the networking subsystem. Our goal over the next few years is for the Linux kernel network stack to rival or exceed that of FreeBSD.’ Two interesting bullet points listing “responsibilities”: Improve IPv6 support in the kernel, and eliminate perf and stability issues. FB is one of the worlds largest IPv6 deployments; Investigate and participate in emerging protocols (MPTCP, QUIC, etc) discussions, implementation, experimentation, tooling, etc. Read more of this story at Slashdot.

Justin.tv Shuts Down Amid Reports Google Is Acquiring Twitch

An anonymous reader writes Twitch today announced that the Justin.tv website, mobile apps, and APIs are no longer in service. A very simple explanation is given for the shutdown: since rebranding the company to Twitch Interactive in February 2014, all resources are now focused on Twitch.tv. The news today will almost certainly further fuel the rumors that Google is acquiring, or has already acquired, Twitch. Purchases are often followed by consolidation, as well as cutting off any excess limbs. Read more of this story at Slashdot.

European Rosetta Space Craft About To Rendezvous With Comet

Taco Cowboy (5327) writes After a long 10-year journey spanning some four (4) billion kilometers, Rosetta, an interplanetary space craft from the ESA (European Space Agency), is on its final approach to comet Comet 67P (or comet Churyumov-Gerasimenko). The last in a series of 10 thruster firings over the past few months has slowed Rosetta to the pace of a person walking, about two miles per hour relative to the speed of its target at a distance of about 60 miles. Photographs have already revealed a surprisingly irregular shape for the 2.5-mile-wide comet, possibly an amalgamation of two icy bodies or a result of uneven weathering during previous flybys. From a distance, the blurry blob initially looked somewhat like a rubber duck. As the details came into the focus, it now more resembles a knob of ginger flying through space. Wednesday marks a big moment for space exploration: After a few thruster rockets fire for a little over six minutes, Rosetta will be in position to make the first-ever rendezvous with that comet nickname ‘Rubber Duck.’ ‘This burn, expected to start at 11 a.m. central European time, will tip Rosetta into the first leg of a series of triangular paths around the comet, according to the Paris-based European Space Agency, or ESA, which oversees the mission. Each leg will be about 100 kilometers (62 miles) long, and it will take Rosetta between three to four days to complete each leg. There will be a live streaming webcast of Rosetta’s Aug. 6 orbital arrival starting at 8 a.m. GMT via a transmission from ESA’s spacecraft operations centre in Darmstadt, Germany. Also at the BBC.
