New Raspberry Pi Model B+ 202

Posted by samzenpus from the latest-and-greatest dept.
mikejuk writes The Raspberry Pi foundation has just announced the Raspberry Pi B+. The basic specs haven't changed much — same BC2835 and 512MB of RAM and the $35 price tag. There are now four USB ports, which means you don't need a hub to work with a mouse, keyboard and WiFi dongle. The GPIO has been expanded to 40 pins, but don't worry: you can plug your old boards and cables into the lefthand part of the connector, and it's backward compatible. As well as some additional general purpose lines, there are two designated for use with I2C EEPROM. When the Pi boots it will look for custom EEPROMs on these lines and optionally use them to load Linux drivers or setup expansion boards. Expansion boards can now include identity chips that when the board is connected configures the Pi to make use of them — no more manual customization. The change to a micro SD socket is nice, unless you happen to have lots of spare full size SD cards around. It is also claimed that the power requirements have dropped by half, to one watt, which brings the model B into the same power consumption area as the model A. Comp video is now available on the audio jack, and the audio quality has been improved. One big step for Raspberry Pi is that it now has four holes for mounting in standard enclosures.

Submission + - Microsoft announces Surface tablet, with kickstand and fold-out keyboard (extremetech.com) 7

MrSeb writes: "At its much-discussed “big unveil” this evening, Microsoft did indeed launch a tablet — but rumors that the device would showcase a Barnes & Noble partnership were misplaced. Instead, Microsoft showed a vision for a next-gen PC that combines the portability of a tablet with a minimalistic fold-out keyboard and integrated kickstand. Microsoft’s idea for the tablet (confusingly called Surface) is a device that integrates a better keyboard option than typing on the screen without adding size or weight. That’s where the new keyboard — which doubles as a screen cover — kicks in. At 3mm thick, it adds virtually nothing to the device’s size, but it opens up a world of inputs. There are two covers available — the Touch Cover (very thin) and the Type Cover (with proper, tactile keys). Microsoft is touting the device’s magnesium body, vapor-deposited construction, full PC functionality, and additional features like being the first tablet to showcase a 2×2 MIMO wireless antenna. Windows RT (ARM) and x86 versions are both in the works, with the x86 version apparently having a higher quality screen. No word on hardware specs yet; Microsoft is claiming it “rivals the best ultrabooks” and uses less power than the Core i5. I'm a little bit dubious on that front — and also dubious about how Microsoft's hardware partners will receive this new, rather competitive offering..."

Submission + - Schneier: Stuxnet cyberattack by US a 'destabilizing and dangerous' action (networkworld.com)

Submitted by alphadogg
alphadogg writes: Revelations by The New York Times that President Barack Obama in his role as commander in chief ordered the Stuxnet cyberattack against Iran's uranium-enrichment facility two years ago in cahoots with Israel is generating controversy, with Washington in an uproar over national-security leaks. But the important question is whether this covert action of sabotage against Iran, the first known major cyberattack authorized by a U.S. president, is the right course for the country to take. Are secret cyberattacks helping the U.S. solve geopolitical problems or actually making things worse? Bruce Schneier, whose most recent book is "Liars and Outliers," argues the U.S. made a mistake with Stuxnet, and he discusses why it's important for the world to tackle cyber-arms control now.

Comment Datacenter location is more complex than cooling.. (Score 2) 195

by akirchhoff (#38456412) Attached to: The Fjord-Cooled Data Center

You have to figuring in more than just cooling:

1. How much does power cost in the location
2. How much power is available. Data centers suck huge amounts no matter how efficient.
3. Do people want that heat island near them.
4. Is the data center near the consumer of its resources? Latency still matters to me.

Ask Slashdot: Science Sights To See? 363

First time accepted submitter steevven1 writes "My girlfriend and I are planning a long trip across the United States for this summer, and we'd like to see the usual sights, but we both have a bit of a geeky side, and we were trying to think of science-related marvels to see along the way. So far, we have thought of places like the Very Large Array in New Mexico and Fermilab in Illinois. Any suggestions?"

Swiss Geologist On Trial For Causing Earthquakes 258

Posted by kdawson from the should-have-called-dig-safe dept.
Hugh Pickens writes "BBC reports that Markus Haering's company had been working with the authorities in Basel, Switzerland to try to convert the heat in deep-seated rocks into electricity, but the project was suspended in 2006 when drilling triggered earthquakes, one of them with a magnitude of 3.4, leading Haering's company to pay out $9M in damages. Haering's team planned to drill a series of holes penetrating up to 3 miles (4.8 km) underground with water being pumped onto rocks with a temperature of more than 195C. Basel's location on top of a fault line – the upper Rhine trench – had been deliberately chosen because the heat was closer to the Earth's surface. A risk assessment has since shown that the prospect of further quakes is too high to continue drilling in the city. Haering faces up to five years in prison if the judge finds he intentionally damaged property. Haering has admitted the 3.4 magnitude earthquake was stronger than he had expected and that his team 'had very little knowledge of seismicity' before starting to drill, but called the quakes 'a learning process for everyone involved.' Despite Haering's trial, the Swiss appetite for geothermal projects has not diminished. Engineers are beginning preliminary drilling in Zurich to see whether that area was suitable for a similar scheme, and St. Gallen, in eastern Switzerland, plans to start work on its own geothermal project next year. Drilling efforts are being closely watched in the US, where the energy department is sponsoring more than 120 geothermal energy projects in several states."

Microsoft Secret Prototype Phone Stolen 249

Posted by ScuttleMonkey from the microsoft-to-develop-more-secure-pockets dept.
bossanovalithium writes to tell us that details are emerging about the theft of a top secret prototype mobile device stolen from an executive's pocket. Time to start watching eBay. "There are fears that leaks regarding the features and early bugs in the software could mar the launch of Windows Mobile 6.5 which the company hopes will give it the edge over the iPhone and the new Google Android operating system. The new product includes support for touch-screen technology similar to that found on the Apple iPhone. Among the features offered in the new service unveiled by Microsoft's chief executive, Steve Ballmer, on Tuesday, is a version of Windows Marketplace for Mobiles, which is set to compete with the popular Apple's App Store and provide easy ways to download music and products to mobiles.
