Cell Phone Powered By Urine 88

sciencehabit writes "The newest source of battery power for your cell phone is both cheap and abundant. Scientists report that microbial fuel cells using human urine can directly power a cell phone battery. However, the devices are not quite portable enough to come in handy during a marathon pub crawl. One consists of six, 4-inch-long ceramic cylinders; the other is a network of 25 smaller fuel cells borrowed from the team's waste-fueled EcoBot. And urine-powered conversations would have to be short and sweet. After 24 hours of charging, a Samsung phone stayed alive for 25 minutes—enough to send several texts and make a 6-minute, 20-second call."

BitTorrent Sync Beta Released 69

Nerval's Lobster writes "BitTorrent Sync has reached its Beta milestone. The tool, which allows for secure file-syncing between devices, has been under development for quite some time: BitTorrent released a limited pre-Alpha program in January, planning to use any feedback to refine the software before release. Key features include the use of peer-to-peer technology for direct synchronization, rather than storing files in the cloud—a key differentiator from similar storage services on the market. 'It fits into our overall goal of making a better Internet using P2P,' BitTorrent Inc. told TorrentFreak when that pre-Alpha rolled out. In the intervening months, of course, former federal contractor Edward Snowden leaked a variety of top-secret documents about NSA surveillance to The Guardian, kicking off several weeks' worth of discussions and handwringing over government snooping. Several of those documents suggested that an NSA program codenamed PRISM siphoned user data from nine major technology companies, including Google and Microsoft; the named companies have stridently denied any involvement. Those revelations about the NSA—even if totally unsurprising to the paranoid—could kick off renewed interest in software tools capable of securing data against prying eyes. In other words, this could be just the moment for something like BitTorrent Sync to hit the market. 'Sync is a response to what we see as real, fundamental challenges to personal data movement: the limitations on speed, size, space, privacy, and security that come with cloud dependency,' read a July 17 note on the BitTorrent Blog."

Eben Upton Muses on the Raspberry Pi, Scratch and, His Love For Parallela 71

super_rancid writes "In a 7,000 word interview with Raspberry Pi's founder posted on TuxRadar.com, Eben Upton talks about the challenges of managing such a successful project, what may be in the Raspberry Pi mark 2, and why he wishes he'd backed the Parallela Kickstarter." On interesting answer: "We were thinking of booting into Python or booting into Scratch. For younger kids, boot into Scratch. Have an environment where it’s Linux underneath, boots into Scratch and hold down a key at a particular point during boot and it doesn’t boot into Scratch it just drops into the prompt. So you can play with Scratch for six months, once you’re happy with Scratch you turn over the page and 'Hold down F1 during boot,' and it’s like 'Oh look - it’s a PC!' So I think that’s something we’d really like to do."

America's First Eco-City: Doomed From the Start 258

An anonymous reader writes "Despite backing from the Clinton Climate Initiative, and a $111 million investment from Subway Restaurant mogul Fred DeLuca, a planned city for Central Florida called 'Destiny' was doomed from the start, according to memos retrieved from Florida's Department of Community Affairs. According to state officials, despite a great deal of hype about Destiny, Florida, becoming the first fully sustainable city in the U.S., plans to build the city were rejected almost immediately due to concerns over 'possible urban sprawl, energy inefficient land use patterns, the endangerment of natural resources, and the undermining of agriculture.'"

New Thermocell Could Turn 'Waste Heat' Into Electricity 181

dryriver sends this quote from Phys.org: "Harvesting waste heat from power stations and even vehicle exhaust pipes could soon provide a valuable supply of electricity. A small team of Monash University researchers ... has developed an ionic liquid-based thermocell (abstract). Thermocell technology is based on harnessing the thermal energy from the difference in temperature between two surfaces and converting that energy into electricity. The new thermocell could be used to generate electricity from low grade steam in coal fired power stations at temperatures around 130C. This would be implemented by having the steam pass over the outer surface of the hot electrode to keep it hot while the other electrode is air or water cooled."

How To Compete With NSA By Hacking a Verizon Network Extender 56

New submitter Anita Hunt (lissnup) writes "This snooping hack-in-a-backpack could become a hot Summer accessory, since Reuters reported that 'researchers at iSec hacked into a Verizon network extender, which anyone can buy online, and turned it into a cell phone tower (video interview) small enough to fit inside a backpack capable of capturing and intercepting all calls, text messages and data sent by mobile devices within range.'"

San Onofre's Closure: What Was Missed 88

Lasrick writes "John Mecklin explores the context that was missed when the LA Times and the San Diego Union Tribune reported on the closing of the remaining two San Onofre nuclear reactors: 'U-T San Diego published a similar flurry of well-reported stories that covered the basics of the reasons for the closure, as well as the impact on consumers, workers, and the electricity supply. At both papers, coverage included infographics that effectively explained the problem that forced the plant to close—vibration that caused wear in tubes for the plant's steam generators. (The Times's tick-tock takeout on the history of the steam generator snafu, published in July, is especially comprehensive.) The specifics of the San Onofre closing were covered well and thoroughly. The context within which those basics reside, however, was far less well-examined, and the two major newspapers closest to the San Onofre plant both therefore missed a real opportunity to inform readers about the major energy choices California and the country will need to make in the coming decade.' Excellent work at the Columbia Journalism Review."

Samsung Ups Ante In Smartphone Size Wars: 6.3 Inches 221

New submitter jarold writes to note that Samsung has launched two extra-large cellphones: a 6.3 inch LTE ready version, and a 5.8 inch version. "Branded as Galaxy Mega, one would struggle to fit [either in a] pocket or use it with just one hand. The good thing, it is only 8mm thin and weighs under 200 grams. More portable than a tablet, it comes with a durable polycarbonate body. Unlike most of Samsung's latest smartphones, it does not have a super AMOLED panel. Instead, it has an HD super clear LCD display, which is bright enough to please most users. It features split screen and multitasking between video and other apps." For a phone that big, users might need to brush up on their side-talking skills.

Moto X Demo Video Reveals Google's Android Superphone 151

MojoKid writes with word that "A tech demo posted to YouTube shows off Motorola's upcoming Moto X smartphone, a seemingly high-end device that is sure to win over a few fans with its wealth of new tricks and features. The Moto X handset, which is launching exclusive to Rogers in Canada (no mention of U.S. market carriers) this August, will be available in black and white, but a key selling point of the device comes from its voice activated features. The tech demo heavily emphasizes Google Now, which Moto X users can engage without touching the device. In the demo, a woman is shown asking Google Now what the weather will be like in Toronto while she types away on a computer, never having to reach down to tap the handset. It was also previously leaked that the Moto X will ship with a 4.4-inch display (1280x720), 1.7GHz dual-core Qualcomm Snapdragon 8960 processor, 2GB of RAM, 16GB of internal storage, 10MP rear-facing camera, 2MP front-facing camera, and of course Android 4.2 Jelly Bean." With a marketing budget said to include up to half a billion (!) dollars from Google, it's hard to imagine that any leaks are actually unintentional.

Plug Touts Expandable Storage Via USB Drives Plugged In At Home 87

DeviceGuru writes with an excerpt that may be of interest especially for mobile users with cheap, always available wireless data: "An OpenWRT Linux-based hardware adapter called Plug designed for unifying USB-connected storage met its $69,000 Kickstarter pledge goal in 12 hours. The tiny Plug device eschews cloud storage for a localized approach whereby an app or driver installed on each participating computer or mobile device intercepts filesystem accesses, and redirects data reads and writes to storage drives attached to the user's Plug device. The Plug enjoyed one of the fastest fulfillments in Kickstarter history, meeting its goal in 12 hours, and has already soared to over $223,000 in funding."

Ask Slashdot: Enterprise Level Network Devices For Home Use? 241

First time accepted submitter osho741 writes "I was wondering if anyone has enterprise level networking devices set up at home? I seem to go through at least 1 wireless consumer grade router a year or so. I can never seem to find one that last very long under just normal use. I thought maybe I would have better luck throwing together a network using used enterprise equipment. Has anyone done this? What would you recommend for a network that maxes out at 30mbps downstream from the ISP and an internal network that should be able to stream 1080p movies to 3 or 4 devices from a media server? Any thoughts and or suggestions are welcome."

Casting a Jaundiced Eye On AnTuTu Benchmark Claims Favoring Intel 82

MojoKid writes "Recently, industry analysts came forward with the dubious claim that Intel's Clover Trail+ low power processor for mobile devices had somehow seized a massive lead over ARM's products, though there were suspicious discrepancies in the popular AnTuTu benchmark that was utilized to showcase performance. It turns out that the situation is far shadier than initially thought. The version used in testing with the benchmark isn't just tilted to favor Intel — it seems to flat-out cheat to accomplish it. The new 3.3 version of AnTuTu was compiled using Intel's C++ Compiler, while GCC was used for the ARM variants. The Intel code was auto-vectorized, the ARM code wasn't — there are no NEON instructions in the ARM version of the application. Granted, GCC isn't currently very good at auto-vectorization, but NEON is now standard on every Cortex-A9 and Cortex-A15 SoC — and these are the parts people will be benchmarking. But compiler optimizations are just the beginning. Apparently the Intel code deliberately breaks the benchmark's function. At a certain point, it runs a loop that's meant to be performed 32x just once, then reports to the benchmark that the task completed successfully. Now, the optimization in question is part of ICC (the Intel C++ compiler), but was only added recently. It's not the kind of procedure you'd call by accident. AnTuTu has released an updated "new" version of the benchmark in which Intel performance drops back down 20-50%. Systems based on high-end ARM devices again win the benchmark overall, as they did previously."

Ask Slashdot: Low-Latency PS2/USB Gaming Keyboards? 177

An anonymous reader writes "I've a cheap but low latency mouse (A4Tech) and I noticed my trusty old wired Logitech PS/2 keyboard seems at least 50ms slower (if not more) than the mouse when I test with those reaction time sites. I even increased finger travel distance over my mouse button to make it fairer and the difference still remains. So either the tests are slower with keyboards or my keyboard is high latency. Assuming the latter any suggestions for a good reasonably priced gaming keyboard? Extra function keys might be nice but since my hands aren't big what would be better is being able to output a custom key/combo if you hold down (special?) keys while pressing another key. For example I could configure it so if I hold down "Special Key 1" with pinkie or thumb and press 4 it actually outputs 9, and if I hold down shift as well it outputs shift+9 (and not just 9). Being able to replace the capslock key function and have it behave as another key (or a special modifier) would be a bonus — I've never needed capslock and have probably used it more by mistake than for its normal function, or to test how badly a PC has hung."

Limitations and All, Chromebooks Appear To Be Selling 126

puddingebola writes "A number of different websites are commenting on NPD's consumer research numbers that claim Chromebooks are getting 20-25% of the sub-$300 PC market. From the article: 'The NPD says that Google's Chromebook has now gained 20 to 25 percent of the sub-$300 laptop market in the U.S. That's a huge gain for a computer that's only been on the market for two years. It's even more impressive when you consider that Chromebooks were seen as nothing but a self-serving experiment on the part of Google for the first year of their existence.' Stephen Vaughan-Nichols is also blogging about this over at ZDnet. While the PC market shrank again in the second quarter of 2013, Chromebooks seem to have grown."

Energy Production Causes Big US Earthquakes 211

ananyo writes "Natural-gas extraction, geothermal-energy production and other activities that inject fluid underground have caused numerous earthquakes in the United States, scientists have reported in a trio of papers in Science (abstracts here, here and here). Most of these quakes have been small, but some have exceeded magnitude 5.0. They include a magnitude-5.6 event that hit Oklahoma on 6 November 2011, damaging 14 homes and injuring two people."

New Analysis Casts Doubt On Intel's Smartphone Performance vs. ARM Devices 94

MojoKid writes "A few weeks ago, the analyst company ABI Research published a report claiming that Intel's new CloverTrail+ platform (dual-core Medfield) for smartphones was significantly faster and more power efficient than anything ARM's various partners were shipping. If you follow the smartphone market, that was a very surprising claim. Medfield was a decent midrange platform when it launched in 2012, but Intel made it clear that its goal for Medfield was to compete with other platforms in its division — not seize the performance crown outright. Further investigation by other analysts has blown serious holes in the ABI Research report. Not only does it focus on a single, highly questionable benchmark (AnTuTu), the x86 version of that benchmark is running different code than the ARM flavors. Furthermore, the recently released Version 3.3 of the test is much faster on Intel hardware than on any of the other platforms. But even with those caveats in place, the ABI Research report is bad science. Single-source performance comparisons almost inevitably are."
