802.11ad Will Knock Your Socks Off, Says Interop Panel 174

Posted by timothy
from the but-magnum-will-blow-them-all-away dept.
alphadogg writes "While the Wi-Fi world is rightly abuzz over the rapidly approaching large-scale deployment of the new 802.11ac standard, experts at an Interop NY panel said this week that the 802.11ad standard is likely to be even more transformative. '802.11ac is an extension for pure mainstream Wi-Fi,' said Sean Coffey, Realtek's director of standards and business development. 'It's evolutionary. ... You're not going to see dramatically new use cases." By contrast, 802.11ad adds 60GHz connectivity to the previously used 2.4GHz and 5GHz frequencies, potentially providing multi-gigabit connection speeds and dramatically broadening the number of applications for which wireless can be used."

The Computer Science Behind Facebook's 1 Billion Users 113

Posted by timothy
from the yet-they-keep-most-recent-instead-of-top-stories dept.
pacopico writes "Much has been made about Facebook hitting 1 billion users. But Businessweek has the inside story detailing how the site actually copes with this many people and the software Facebook has invented that pushes the limits of computer science. The story quotes database guru Mike Stonebraker saying, 'I think Facebook has the hardest information technology problem on the planet.' To keep Facebooking moving fast, Mark Zuckerberg apparently instituted a program called Boot Camp in which engineers spend six-weeks learning every bit of Facebook's code."

Why Worms In the Toilet Might Be a Good Idea 124

Posted by timothy
from the as-if-it-wasn't-obvious dept.
derekmead writes "Billions worldwide still don't have access to proper sanitation, and those that do still require a ton of water and electricity to keep waste flowing. A French company is offering one solution: Use turd-eating worms to compost waste right at the source. Ecosphere Technologies has developed an outhouse that, rather than relying on chemicals like a port-a-john, relies on about a pound of red wiggler worms. A new installation in Quebec uses imported worms, placed inside of a mixture of dung and straw underneath to toilet, to devour feces delivered to them by a conveyor belt system. (When someone uses the toilet, pee filters through sand to wash away, while a pedal allows the user to transport their poo to the worm space.) The whole system uses no water or electricity, and a series of passive vents allegedly keeps the toilet smelling great. The company claims it can be used 10,000 times without servicing, which is far better than what a port-a-potty can boast, although with a current price tag of $40k for the worm system, port-a-potties are still a lot cheaper."

Foxconn Workers On Strike Over iPhone 5 Production 184

itwbennett writes "That army of robotic assembly line workers we mentioned yesterday apparently can't get started soon enough. As many as 3,000-4,000 workers are on strike at Foxconn's Zhengzhou factory, upset at stricter quality control requirements with the iPhone 5 and having to work through a national holiday this week. 'According to workers, multiple iPhone 5 production lines from various factory buildings were in a state of paralysis for the entire day,' China Labor Watch said. Sina Weibo and Tencent Weibo are both blocking searches in Chinese for 'Foxconn strikes.'"

Most SSDs Now Under a Dollar Per Gigabyte 187

Posted by Soulskill
from the more-bits-per-buck dept.
crookedvulture writes "SSD prices continue plummeting. In just the past quarter, street prices have fallen by double-digit percentages for most models, with some slashed by 30% or more. We've reached the point where the majority of drives cost less than a dollar per gigabyte, and that's without the special coupon codes and mail-in rebates usually attached to weekly deals. Lower-capacity drives seem more resistant to deep price cuts, making 120-256GB offerings the best values right now. It's nice to see a new class of devices go from prohibitively expensive to eminently affordable in such a relatively short amount of time."

The Coming Internet Video Crash 419

Posted by Soulskill
from the wear-your-seat-belts-kids dept.
snydeq writes "First, it was data caps on cellular, and now caps on wired broadband — welcome to the end of the rich Internet, writes Galen Gruman. 'People are still getting used to the notion that unlimited data plans are dead and gone for their smartphones. The option wasn't even offered for tablets. Now, we're beginning to see the eradication of the unlimited data plan in our broadband lines, such as cable and DSL connections. It's a dangerous trend that will threaten the budding Internet-based video business — whether from Netflix, Hulu, iTunes, Windows Store, or Google Play — then jeopardize Internet services of all sorts. It's a complex issue, and though the villains are obvious — the telecom carriers and cable providers — the solutions are not. The result will be a metered Internet that discourages use of the services so valuable for work and play.'"

from the because-why-not dept.
ptorrone writes "Adafruit, the NYC based open-source hardware company led by Ladyada released their open-source Raspberry Pi WebIDE alpha today. Its goal is to be 'The easiest way to develop code on your Raspberry Pi.' To get up and running head on over to learn.adafruit.com/webide and follow the installation and setup instructions. It uses Bitbucket, and any code changes you make will be synced to your Bitbucket account. Adafruit chose Bitbucket over GitHub because they offer free secure accounts, which is very important for a Web-based IDE."

Over 60% of Android Malware Hides In Fake Versions of Popular Apps 111

Posted by Soulskill
from the 60-percent?-that's-almost-80-percent! dept.
An anonymous reader writes "Like any popular platform, Android has malware. Google's mobile operating system is relatively new, however, so the problem is still taking form. In fact, it turns out that the larger majority of threats on Android come from a single malware family: Android.FakeInstaller, also known as OpFake, which generates revenue by silently sending expensive text messages in the background. McAfee says that the malware family makes up more than 60 percent of Android samples the company processes."

Ask Slashdot: Am I Too Old To Retrain? 418

Posted by Soulskill
from the not-unless-you're-an-mma-fighter dept.
Talcyon writes "I'm a 40-year-old developer, and it's become apparent that my .NET skillset is woefully out of date after five years of doing various bits of support. I tried the 'Management' thing last year, but that was a failure as I'm just not a people person, and a full-on development project this year has turned into a disaster area. I'm mainly a VB.NET person with skills from the .NET 2.0 era. Is that it? Do I give up a career in technology now? Or turn around and bury myself in a support role, sorting out issues with other people's/companies' software? I've been lurking around Slashdot for many years now, and this question occasionally comes up, but it pays to get the opinions of others. Do I retrain and get back up to speed, or am I too old?"

sfcrazy writes "Samsung has created a new Linux file system called F2FS. Jaegeuk Kim of Samsung writes on the Linux Kernel Mailing List: F2FS is a new file system carefully designed for the NAND flash memory-based storage devices. We chose a log structure file system approach, but we tried to adapt it to the new form of storage. Also we remedy some known issues of the very old log structured file system, such as snowball effect of wandering tree and high cleaning overhead."

How To Steal a Space Shuttle 130

Posted by Soulskill
from the discovering-an-enterprising-endeavor dept.
An anonymous reader tips a piece by Jason Torchinsky at Jalopnik, who attended the California Science Center's press conference about moving Space Shuttle Endeavour through Los Angeles to its final resting place. While he was there, he noticed that security for the event was focused less on the shuttle than on keeping the city itself safe. So, after a helpful LAPD officer suggested it would be impossible for a supervillain to make off with OV-105, Torchinsky went ahead and made a plan to do just that. All he needs is a submarine, a score of Sikorsky CH-53E heavy-lift helicopters, a salvaged and disguised Buran spaceplane, and the assistance of Switzerland.

Boeing Proposes Using Gas Clouds To Bring Down Orbital Debris 147

Posted by Soulskill
from the anti-space-station-weaponry dept.
cylonlover writes "Boeing has filed a patent application for a method of disposing of dead satellites and other debris orbiting the earth by hitting them with a puff of gas. The method, which is still at the conceptual stage, is designed to slow down satellites, forcing them to re-enter the atmosphere without sending up more space junk that itself will need disposing of. The idea is to send a small satellite into orbit containing a gas generator. This generator can be a tank of cryogenic gas, such as xenon or krypton, or a device designed to vaporize a heavy metal or some relatively heavy elements like fluorine, chlorine, bromine, or iodine. This gas would be released as a cloud in the same orbit as the debris, but traveling in the opposite direction." Clever of them to patent this, since knock-off space-junk removal systems are in such high demand.

Boston Airport Replacing X-ray Body Scanners 119

Posted by Soulskill
from the we-have-all-kinds-of-light-waves-to-blast-you-with dept.
OverTheGeicoE writes "Boston's Logan International Airport is in the process of replacing its X-ray body scanners with millimeter-wave ones. According to the article, nine of the new scanners have been installed already, and ultimately 27 of these scanners will replace the 17 X-ray backscatter scanners that were installed in March of 2010. The new devices are 'being installed come with software that replaces "passenger-specific images" — or nearly naked views of travelers — with generic outlines that highlight only anomalies such as belts, jewelry, wallets — or guns or bombs.' Perhaps this will help TSA workers avoid being part of a cancer cluster. Some speculate that TSA will ultimately eliminate all of its X-ray body scanners."

itwbennett writes "On Thursday, FCC Chairman Julius Genachowski laid out plans to make 300MHz more spectrum available by 2015. Among the blocks that will be auctioned in the AWS (Advanced Wireless Services) band is a band between 1755MHz and 1780MHz, where a commercial user would share the spectrum with current government users." Genachowski's full speech (PDF) is available online.
