Ask Slashdot: Why Buy a Raspberry Pi When I Have a Perfectly Good Cellphone? 273

Posted by samzenpus from the expensive-knock-off dept.
scorp1us writes "I've been looking into getting a Raspberry Pi, but I end up needing a case, a display, and some way to power it, and wanting some degree of portability. It seems to me that even the most outdated cellphone has far superior features (screen, touch screen, Wifi, 3g/4g camera(s), battery etc) in a much better form factor. The only thing that is missing are the digital/analog in/out pins. So why not flip it around and make a USB or bluetooth peripheral board with just the pins? I've been looking for this and can't find any, but does anyone know of any in the corners of the internet? I don't care what phone platform."

Landsat's First Images Show Rocky Mountains In Stunning Detail 63

Posted by samzenpus from the more-real-than-real dept.
Zothecula writes "We haven't heard anything from NASA's Landsat Data Continuity Mission (LDCM) spacecraft since its launch in February, but the satellite is now ready to start sending its first images back home. The first batch of photos are part of a three-month testing period, and show the meeting of the Great Plains with the Front Ranges of the Rocky Mountains in Wyoming and Colorado. Viewed from space, it's already a pretty spectacular scene, but the images from the LDCM managed to enhance it even further."

Matthew Garrett Has a Fix To Prevent Bricked UEFI Linux Laptops 74

Posted by timothy from the and-it-can-be-yours-for-free dept.
hypnosec writes "UEFI guru Matthew Garrett, who cleared the Linux kernel in Samsung laptop bricking issues, has come to rescue beleaguered users by offering a survival guide enabling them to avoid similar issues. According to Garrett, storage space constraints in UEFI storage variables is the reason Samsung laptops end up bricking themselves. Garrett said that if the storage space utilized by the UEFI firmware is more than 50 percent full, the laptop will refuse to start and ends up being bricked. To prevent this from happening, he has provided a Kernel patch."

ICANN Reveals Regional Winners of New gTLDs 69

Posted by timothy from the the-envelope-please dept.
hypnosec writes "The Internet Corporation for Assigned Names and Numbers has approved and released a list of domain names as per its new global Top Level Domain plans. A total of 27 domain names have been cleared for use by ICANN, and all of them are non-English domain names. Consisting of Chinese and Arabic names, the list of domain names seems to be mostly for regional companies, prominent among which are the .Qatartelecom and .Mozaic domains."

Earthquakes Deposit Gold In Fault Zones 55

Posted by samzenpus from the shake-rattle-and-gold dept.
sciencehabit writes "Gold deposits may be created in a flash—literally. Along fault zones deep within Earth's crust, small cavities filled with fluids rich in dissolved substances such as gold and silicate minerals can expand suddenly to as much as 130,000 times their former size during a major earthquake, a new analysis suggests. In such circumstances, pressure drops accordingly, driving a process the scientists call flash evaporation. And when the pressure in the cavity suddenly drops, so does the solubility of minerals in the water there. Along with substantial quantities of quartz, large earthquakes could deposit as much as 0.1 milligrams of gold along each square meter of a fault zone's surface in just a fraction of a second Typical rates of seismicity along a fault, such as the San Andreas fault zone shown in the main image, could generate a 100-metric-ton deposit of gold in less than 100,000 years."

The Pirate Bay's Oldest Torrent Is Revolution OS 130

Posted by samzenpus from the back-in-the-day dept.
jrepin writes "After nearly 9 years of seeding The Pirate Bay's oldest working torrent is still very much alive. Interestingly, the torrent is not a Hollywood classic nor is it an evergreen music album. The honor goes to a pirated copy of Revolution OS, a documentary covering the history of Linux, GNU and the free software movement."

How Beer Gave Us Civilization 325

Posted by samzenpus from the the-cause-and-solution-to-all-of-life's-problems dept.
Hugh Pickens writes "Jeffrey P. Khan writes in the NY Times about how recent anthropological research suggests that human's angst of anxiety and depression ultimately results from our transformation, over tens of thousands of years, from biologically shaped, almost herd-like prehistoric tribes, to rational and independent individuals in modern civilization. The catalyst for suppressing the rigid social codes that kept our clans safe and alive was fermented fruit or grain. 'Once the effects of these early brews were discovered, the value of beer must have become immediately apparent,' writes Khan. 'With the help of the new psychopharmacological brew, humans could quell the angst of defying those herd instincts. Conversations around the campfire, no doubt, took on a new dimension: the painfully shy, their angst suddenly quelled, could now speak their minds.' Examining potential beer-brewing tools in archaeological remains from the Natufian culture in the Eastern Mediterranean, the team concludes that 'brewing of beer was an important aspect of feasting and society in the Late Epipaleolithic' era. In time, humans became more expansive in their thinking, as well as more collaborative and creative. A night of modest tippling may have ushered in these feelings of freedom — though, the morning after, instincts to conform and submit would have kicked back in to restore the social order. Today, many people drink too much because they have more than average social anxiety or panic anxiety to quell — disorders that may result, in fact, from those primeval herd instincts kicking into overdrive. But beer's place in the development of civilization deserves at least a raising of the glass. As the ever rational Ben Franklin supposedly said, 'Beer is living proof that God loves us and wants us to be happy.'"

NASA Restarts Plutonium Production 139

Posted by timothy from the yeah-but-now-it's-non-planetary dept.
Celarent Darii writes "In what looks like good news for the American Space program, NASA has restarted production of plutonium. According to the article, after the closure of Savannah Rivers reactor NASA purchased plutonium from Russia, but since 2010 this was no longer possible. The native production of plutonium is a step forward for the space program to achieve the energy density for long term space exploration."

Manga Girls Beware: Extra Large Eyes Caused Neanderthal's Demise 290

Posted by Unknown Lamer from the four-eyes-stays-alive dept.
An anonymous reader writes "The BBC reports on a new study of prehistoric skulls which suggests that Neanderthals became extinct because they had larger eyes than our species. As a consequence of having extra sized eyes, an average 6 millimeters larger in radius, more of their backside brain volume was devoted to seeing, at the expense of frontal lobe high-level processing of information and emotions. This difference affected their ability to innovate and socialize the way we, modern people (Homo Sapiens Sapiens) do. When the last Ice Age set on 28,000 years ago, Neanderthals had no sewn clothes and no large organized groups to rely on each other, hastening their fall. Yet, they were not stupid, brutish creatures as portrayed in Hollywood films, they were very, very smart, but not quite in the same league as the Homo Sapiens of Cromagnon."

High Tech Vending Machines Transform IT Support At Facebook 210

Posted by Soulskill from the my-mouse-got-stuck-against-the-glass dept.
Hugh Pickens writes "While getting power cords, replacement keyboards, and other sundry computer accessories to employees who need them sounds easy enough, at many companies the process requires filling out order forms that can take IT departments days to fulfill. That's why Facebook CIO Tim Campos decided to take a more user-friendly approach to this common problem, installing custom-made vending machines around the Facebook campus that dispense computer accessories instead of snacks and sodas. When Facebook engineers spill coffee on their keyboard (a common mishap), they head to a nearby vending machine instead of hitting up their IT guy or just grabbing a replacement from a nearby cabinet. They swipe their badge, key in their selection and voila — a brand new keyboard drops down for them to take. According to Campos, they've reduced the cost of managing replacement accessories by about 35%. While products found in the vending machines are free, items are clearly marked with price tags so employees can see the retail value of each accessory they take. The new vending machines also require all employees to swipe their badge before making a selection. That means each and every power cord, keyboard and screen wipe they take can be traced back to their name, ensuring that the system won't be abused. 'I like the assumption that employees will do the right thing,' writes Alexis Madrigal. 'The swipe means that everyone's requests are tracked and I'm sure some algorithm somewhere is constantly sorting the data to see if anyone has pulled 10 sets of headphones out of the system.'"

Testing an Ad-Free Microtransaction Utopia 248

Posted by Soulskill from the nobody-likes-to-see-how-the-internet-sausage-is-made dept.
MrAndrews writes "After reading a Slashdot story about adblocking and the lively discussion that followed, I got to wondering how else sites can support themselves, if paywalls and ads are both non-starters. Microtransactions have been floated for years, but never seem to take off, possibly because they come off as arbitrary taxation or cumbersome walled-garden novelties. Still, it seems like the idea of microtransactions is still appealing, it's just the wrapping that's always been flawed. I wanted to know how viable the concept really was, so I've created a little experiment to gather some data, to put some real numbers to it. It's a purely voluntary system, where you click 1, 2 or 3-cent links in your bookmark bar, depending on how much you value the page you're visiting. No actual money is involved, it's just theoretical. There's a summary page that tells you how much you would have spent, and I'll be releasing anonymized analyses of the data in the coming weeks. If you're game, please check out the experiment page for more information, and give it a go. Even if you only use it once and forget about it, that says something about the concept right there."

Ask Slashdot: Building a Cheap Computing Cluster? 160

Posted by timothy from the when-freecycle-just-doesn't-make-sense dept.
New submitter jackdotwa writes "Machines in our computer lab are periodically retired, and we have decided to recycle them and put them to work on combinatorial problems. I've spent some time trawling the web (this Beowulf cluster link proved very instructive) but have a few reservations regarding the basic design and air-flow. Our goal is to do this cheaply but also to do it in a space-conserving fashion. We have 14 E8000 Core2 Duo machines that we wish to remove from their cases and place side-by-side, along with their power supply units, on rackmount trays within a 42U (19", 1000mm deep) cabinet." Read on for more details on the project, including some helpful pictures and specific questions.

North Korea Kills Phone Line, 1953 Armistice; Kim Jong Un's Funds Found In China 330

Posted by samzenpus from the international-tantrum dept.
eldavojohn writes "Last week, North Korea promised a "preemptive nuclear strike" prior to a UN vote on new sanctions. Despite the threat, the sanctions were unanimously approved. North Korea has responded by killing a Red Cross hotline with Seoul and claims that it has canceled the 1953 Armistice although the UN notes this cannot be done unilaterally (North Korea attempted the same thing in 2003 and 2009). While everyone thought that Kim Jong Un would ride out the sanctions on slush funds, the United States claims to have found his funds in Shanghai and other parts of China totaling hundreds of millions of dollars. Beijing has reportedly refused to confiscate these funds despite voting for the very UN resolutions sanctioning North Korea that read: 'More specifically, States are directed to prevent the provision of financial services or the transfer of any financial or other assets or resources, including 'bulk cash,' which might be used to evade the sanctions.'"
