How Bird Flocks Resemble Liquid Helium

Slashdot - 2 hours 46 min ago
sciencehabit (1205606) writes "A flock of starlings flies as one, a spectacular display in which each bird flits about as if in a well-choreographed dance. Everyone seems to know exactly when and where to turn. Now, for the first time, researchers have measured how that knowledge moves through the flock—a behavior that mirrors certain quantum phenomena of liquid helium. Some of the more interesting findings: Tracking data showed that the message for a flock to turn started from a handful of birds and swept through the flock at a constant speed between 20 and 40 meters per second. That means that for a group of 400 birds, it takes just a little more than a half-second for the whole flock to turn."

Popular Android Apps Full of Bugs: Researchers Blame Recycling of Code

Slashdot - July 27, 2014 - 11:55pm
New submitter Brett W (3715683) writes The security researchers that first published the 'Heartbleed' vulnerabilities in OpenSSL have spent the last few months auditing the Top 50 downloaded Android apps for vulnerabilities and have found issues with at least half of them. Many send user data to ad networks without consent, potentially without the publisher or even the app developer being aware of it. Quite a few also send private data across the network in plain text. The full study is due out later this week.

Newly Discovered Virus Widespread in Human Gut

Slashdot - July 27, 2014 - 8:35pm
A newly discovered virus has been found by a San Diego State University team to live inside more than half of all human gut cells sampled. Exploring genetic material found in intestinal samples, the international team uncovered the CrAssphage virus. They say the virus could influence the behaviour of some of the most common bacteria in our gut. Researchers say the virus has the genetic fingerprint of a bacteriophage - a type of virus known to infect bacteria. Phages may work to control the behaviour of bacteria they infect - some make it easier for bacteria to inhabit in their environments while others allow bacteria to become more potent. [Study lead Dr. Robert] Edwards said: "In some way phages are like wolves in the wild, surrounded by hares and deer. "They are critical components of our gut ecosystems, helping control the growth of bacterial populations and allowing a diversity of species." According to the team, CrAssphage infects one of the most common types of bacteria in our guts. National Geographic gives some idea why a virus so common in our gut should have evaded discovery for so long, but at least CrAssphage finally has a Wikipedia page of its own.

Off the Florida Coast, Astronauts Train For Asteroid Mission

Slashdot - July 27, 2014 - 7:06pm
Space.com gives an overview of the training that four astronauts are undergoing over 9 days submerged off the coast of Florida near Key Largo. The training mission, dubbed NEEMO 18, is one step toward a proposed (mid-2020s) mission to actually visit a captured asteroid in lunar orbit. In addition to the complications of working outside their school-bus sized habitat while awkwardly suited up in a low-gravity (or at least high buoyancy) environment, their mission also includes a 10-minute communications delay, to simulate the high-latency communications with mission control that would be inevitable for an actual asteroid mission. The experiments astronauts are doing during the mission, which began Monday (July 21), range from the physical to the behavioral. For example, each of the crew members sports a sensor that records how close the crew members work with each other inside the school-bus-size habitat. ... Communications with NEEMO Mission Control is usually constant, and there is the ability to send items to and from the habitat as needed. Also living inside the habitat are two support staff who are assisting with Aquarius maintenance and systems, as required. The crew members also have Internet and phone service to talk with family and friends.

Valencia Linux School Distro Saves 36 Million Euro

Slashdot - July 27, 2014 - 6:04pm
jrepin (667425) writes "The government of the autonomous region of Valencia (Spain) earlier this month made available the next version of Lliurex, a customisation of the Edubuntu Linux distribution. The distro is used on over 110,000 PCs in schools in the Valencia region, saving some 36 million euro over the past nine years, the government says." I'd lke to see more efforts like this in the U.S.; if mega school districts are paying for computers, I'd rather they at least support open source development as a consequence.

A Router-Based Dev Board That Isn't a Router

Slashdot - July 27, 2014 - 5:10pm
An anonymous reader writes with a link to an intriguing device highlighted at Hackaday (it's an Indiegogo project, too, if it excites you $90 worth, and seems well on its way to meeting its modest goal): The DPT Board is something that may be of interest to anyone looking to hack up a router for their own connected project or IoT implementation: hardware based on a fairly standard router, loaded up with OpenWRT, with a ton of I/O to connect to anything. It's called the DPT Board, and it's basically an hugely improved version of the off-the-shelf routers you can pick up through the usual channels. On board are 20 GPIOs, USB host, 16MB Flash, 64MB RAM, two Ethernet ports, on-board 802.11n and a USB host port. This small system on board is pre-installed with OpenWRT, making it relatively easy to connect this small router-like device to LED strips, sensors, or whatever other project you have in mind.

Satellite Images Show Russians Shelling Ukraine

Slashdot - July 27, 2014 - 4:05pm
U.S. officials today made public satellite imagery which they say proves that Russian forces have been shelling eastern Ukraine in a campaign to assist rebel groups fighting Ukraine’s government. The U.S. Office of the Director of National Intelligence, which released the civilian-taken satellite images Sunday, said they show visual evidence that Russia has been firing shells across the border at Ukrainian military forces. Officials also said the images show that Russia-backed separatists have used heavy artillery, provided by Russia, in attacks on Ukrainian forces from inside Ukraine. One image dated July 25/26 shows what DNI claims is “ground scarring” on the Russian side of the border from artillery aimed at Ukrainian military units in Ukraine, as well as the resultant ground craters on the Ukrainian side of the border:

Linus Torvalds: "GCC 4.9.0 Seems To Be Terminally Broken"

Slashdot - July 27, 2014 - 2:40pm
hypnosec (2231454) writes to point out a pointed critique from Linus Torvalds of GCC 4.9.0. after a random panic was discovered in a load balance function in Linux 3.16-rc6. in an email to the Linux kernel mailing list outlining two separate but possibly related bugs, Linus describes the compiler as "terminally broken," and worse ("pure and utter sh*t," only with no asterisk). A slice: "Lookie here, your compiler does some absolutely insane things with the spilling, including spilling a *constant*. For chrissake, that compiler shouldn't have been allowed to graduate from kindergarten. We're talking "sloth that was dropped on the head as a baby" level retardation levels here .... Anyway, this is not a kernel bug. This is your compiler creating completely broken code. We may need to add a warning to make sure nobody compiles with gcc-4.9.0, and the Debian people should probably downgrate their shiny new compiler."

SpaceX Executive Calls For $22-25 Billion NASA Budget

Slashdot - July 27, 2014 - 1:37pm
MarkWhittington (1084047) writes "While participating in a panel called "The US Space Enterprise Partnership" at the NewSpace Conference that was held by the Space Frontier Foundation on Saturday, SpaceX Chief Operating Officer Gwynne Shotwell opined that NASA's budget should be raised to $22-25 billion, according to a tweet by Space Policy Online's Marcia Smith. The theory is that a lot of political rancor has taken place in the aerospace community because of the space agency's limited budget. If the budget were to be increased to pay for everything on the space wish list, the rancor will cease. The statement represents something of a departure of the usual mutual antagonism that exists between some in the commercial space community and some at NASA. Indeed Space Politics' Jeff Foust added a tweet, "Thought: a panel at a Space Frontier Foundation conf is talking about how to increase NASA budget. Imagine that in late 90s." The Space Frontier Foundation has been a leading voice for commercializing space, sometimes at the expense of NASA programs."

Ask Slashdot: What Would You Do With Half a Rack of Server Space?

Slashdot - July 27, 2014 - 12:40pm
New submitter Christian Gainsbrugh (3766717) writes I work at a company that is currently transitioning all our servers into the cloud. In the interim we have half a rack of server space in a great datacenter that will soon be sitting completely idle for the next few months until our lease runs out. Right now the space is occupied by around 8 HP g series servers, a watchguard xtm firewall, Cisco switch and some various other equipment. All in all there are probably around 20 or so physical XEON processors, and probably close to 10 tb of storage among all the machines. We have a dedicated 10 mbs connection that is burstable to 100mbs. I'm curious what Slashdot readers would do if they were in a similar situation. Is there anything productive that could be done with these resources? Obviously something revenue generating is great, but even if there is something novel that could be done with these servers we would be interested in putting them to good use.
