kkleiner writes "A recent report (PDF) from International Energy Agency delivers some dire news: despite 20 years of efforts toward clean energy and a decade of growth in renewable energy, energy production remains as 'dirty' as ever due to worldwide reliance on fossil fuels. With the global demand for energy expected to rise by 25 percent in the next 10 years, a renewed effort toward cleaner energy is desperately needed to avoid detrimental effects to the environment and public health. The report says, 'Coal technologies continue to dominate growth in power generation. This is a major reason why the amount of CO2 emitted for each unit of energy supplied has fallen by less than 1% since 1990. Thus the net impact on CO2 intensity of all changes in supply has been minimal. Coal-fired generation, which rose by an estimated 6% from 2010 to 2012, continues to grow faster than non-fossil energy sources on an absolute basis.'"
zacharye writes "The concept of wearable tech is really buzzing right now as pundits tout smart eyewear, watches and other connected devices as the future of tech. It makes sense, of course — smartphone growth is slowing and people need something to hold on to — but the early 'Explorer' version of Google's highly anticipated Google Glass headset has major problem that could be a big barrier for widespread adoption: Awful battery life." Also, a review of the hardware. The current Glass hardware heads south in less than five hours, which doesn't seem too short relative to similarly powerful devices, but since it is meant to be worn all the time you'd think it would have a large enough battery to make it at least 8 or 10 hours.
coondoggie writes "If smartwatches and other ultra-small devices are to become the text generators of the future, their diminutive keyboards are going to have to be way more useful for, um, big fingered typists. Carnegie Mellon researchers may have the answer to that problem. Called ZoomBoard, the text entry technique is based on the iconic QWERTY keyboard layout." The zoom board paper (PDF) has details. Entering a letter becomes a multi-step process; first you mash the general area of the keyboard containing the letter you want, and eventually it becomes large enough to hit. Test subjects managed to hit 9.3wpm after practice, versus 4.5 wpm for people trying to peck on a teeny-tiny virtual keyboard. They were inspired at least in part by the venerable Dasher input method.
symbolset writes "The Atlantic recently ran an in-depth article about energy resources. The premise is that there remain incalculable and little-understood carbon fuel assets which far outweigh all the fossil fuels ever discovered. The article lists them and discusses their potentials and consequences, both fiscal and environmental. 'The clash occurs when renewables are ready for prime time—and natural gas is still hanging around like an old and dirty but reliable car, still cheap to produce and use, after shale fracking is replaced globally by undersea mining of methane hydrate. Revamping the electrical grid from conventionals like coal and oil to accommodate unconventionals like natural gas and solar power will be enormously difficult, economically and technically.' Along these lines, yesterday the U.S. Geological Survey more than doubled their estimate of Bakken shale oil reserve in North Dakota and Montana to 7.4-11 billion barrels. Part of the push for renewables over the past few decades was the idea that old methods just weren't going to last. What happens to that push if fossil fuels remain plentiful?"
gnujoshua writes "You may recall that last Fall, the LulzBot AO-100 3D printer was awarded the use of the Free Software Foundation's Respects Your Freedom certification mark. Today, the FSF announced certification of the ThinkPenguin TPE-N150USB, Wireless N USB Adapter, which uses the Atheros ARAR9271 chip. The FSF's RYF certification requirements are focused on the software (not the hardware designs) of a product, which in this case was primarily the device firmware and ath9k-htc module in the Linux-libre kernel. (Disclosure: I work for the FSF.) There's also a cool story that is within this story... which is that the firmware for the Atheros AR9271 chipset was released as a result of a small device seller (ThinkPenguin) striking a deal with a large electronic device manufacturer (Qualcomm Atheros) to build a WLAN USB adapter that shipped with 100% free software firmware. This deal was possible largely because two motivated Qualcomm Atheros employees, Adrian Chadd and Luis Rodriguez, made the internal-push to get the firmware released as free software."
Vigile writes "One of the drawbacks to high end graphics has been the lack of low cost and massively-available displays with a resolution higher than 1920x1080. Yes, 25x16/25x14 panels are coming down in price, but it might be the influx of 4K monitors that makes a splash. PC Perspective purchased a 4K TV for under $1500 recently and set to benchmarking high end graphics cards from AMD and NVIDIA at 3840x2160. For under $500, the Radeon HD 7970 provided the best experience, though the GTX Titan was the most powerful single GPU option. At the $1000 price point the GeForce GTX 690 appears to be the card to beat with AMD's continuing problems on CrossFire scaling. PC Perspective has also included YouTube and downloadable 4K video files (~100 mbps) as well as screenshots, in addition to a full suite of benchmarks."
crookedvulture writes "AMD has revealed more details about the unified memory architecture of its next-generation Kaveri APU. The chip's CPU and GPU components will have a shared address space and will also share both physical and virtual memory. GPU compute applications should be able to share data between the processor's CPU cores and graphics ALUs, and the caches on those components will be fully coherent. This so-called heterogeneous uniform memory access, or hUMA, supports configurations with either DDR3 or GDDR5 memory. It's also based entirely in hardware and should work with any operating system. Kaveri is due later this year and will also have updated Steamroller CPU cores and a GPU based on the current Graphics Core Next architecture." bigwophh writes links to the Hot Hardware take on the story, and writes "AMD claims that programming for hUMA-enabled platforms should ease software development and potentially lower development costs as well. The technology is supported by mainstream programming languages like Python, C++, and Java, and should allow developers to more simply code for a particular compute resource with no need for special APIs."
hypnosec writes with word that the OpenWRT team a few days ago released the final version of the project's newest iteration, version 12.09 (codenamed "Attitude Adjustment"). "The final version doesn't support Linux 2.4, because of which the distribution wouldn't run on old router models, for example the Linksys WRT54G models, which have 16MB of RAM and CPUs clocked at 200MHz. The distribution is now based on Linux 3.3 and there is good news for the Raspberry Pi fans as the distribution now supports the credit card-sized computer, along with Ramips routers."
kkleiner writes "For the last 30 years, automation has enabled U.S. manufacturing output to increase and lift profits without having to add any traditional jobs. Now, in the last decade, nearly a third of manufacturing jobs are gone. As manufacturing goes the way of agriculture, the job market must shift into new types of work lest mass technological unemployment and civil unrest overtake these beneficial gains."
Indiana University has replaced their supercomputer, Big Red, with a new system predictably named Big Red II. At the dedication HPC scientist Paul Messina said: "It's important that this is a university-owned resource. ... Here you have the opportunity to have your own faculty, staff and students get access with very little difficulty to this wonderful resource." From the article: "Big Red II is a Cray-built machine, which uses both GPU-enabled and standard CPU compute nodes to deliver a petaflop -- or 1 quadrillion floating-point operations per second -- of max performance. Each of the 344 CPU nodes uses two 16-core AMD Abu Dhabi processors, while the 676 GPU nodes use one 16-core AMD Interlagos and one NVIDIA Kepler K20."
AchilleTalon writes "As many of you may know, there are two main competitors on the Windows platform for embedded software development, namely IAR and Keil. By embedded development, I mean development for microprocessors like the well known 8051 and the likes, not mobile platforms which include a complete OS in first place. I am seeking for alternatives to IAR and Keil in the OSS world. Even if I can find pieces of code here and there, I haven't found yet a fully integrated development platform. Does it exist? What do you use?"
mikejuk writes "The Carnegie Mellon University Biorobotics Lab demonstrates how the snakelike robots can aid search and rescue operations in collapsed buildings. The video appeared more or less at the same time as the current real disaster in Dhaka, Bangladesh where an 8-storey building collapsed, trapping some three thousand people. Bangladesh rescue teams, helped by members of the community, have so far worked with small tools and their bare hands to bring out survivors. Having a snake robot that could provide pictures from within the building would lead to speedier and more effective rescue operations."
symbolset writes "Outbound Intel CEO Paul Otellini created quite a stir when mentioning that touchscreen laptops would reach a $200 price point. CNET is now reporting in an interview with Intel chief product officer Dadi Perlmutter that these touchscreen laptops will run Android on Intel Atom processors at first. 'Whether Windows 8 PCs hit that price largely depends on Microsoft, he said. "We have a good technology that enables a very cost-effective price point," Perlmutter said. The price of Windows 8 laptops "depends on how Microsoft prices Windows 8. It may be a slightly higher price point." ... Perlmutter didn't specify what the Android notebooks will look like, but it's probable they'll be convertible-type devices. He also noted that he expects the PC market to pick up in the back half of the year and heading into 2014 as new devices become available."
An anonymous reader writes with this snippet from ExtremeTech: "Researchers at the University of Washington's aptly named Ubiquitous Computing Lab can turn any LCD monitor in your house into a touchscreen, with nothing more than a $5 sensor that plugs into the wall and some clever software." The system works by measuring changes that your hand creates in the electromagnetic signature of the monitor. Surprisingly, it offers some pretty fine-grained detection, too: "full-hand touch, five-finger touch, hovering above the screen, pushing, and pulling." The "$5 sensor" part is mostly theoretical for now to those of us who don't live in a lab, though; on the other hand, "co-author Sidhant Gupta tells Technology Review that the $5 sensor uses off-the-shelf parts, and the algorithms are included in the paper, so it would be fairly easy for you — or a commercial entity — to recreate the uTouch system."
daltec writes "The $250,000 American Helicopter Society Igor I. Sikorsky Human Powered Helicopter Competition prize, unclaimed since 1980, is now closer than ever to being won. With flights up to ten feet in altitude and lasting over 65 seconds, the prize's strict requirements (thought by many to be impossible to satisfy) have all been met — but not on the same flight. Two teams — AeroVelo in Canada and Gamera II at the University of Maryland — are tantalizingly close to claiming the prize. The Gamera team will be making its latest attempt this weekend."
An anonymous reader writes "Btrfs is the next-gen filesystem for Linux, likely to replace ext3 and ext4 in coming years. Btrfs offers many compelling new features and development proceeds apace, but many users still aren't sure whether it's 'ready enough' to entrust their data to. Anchor, a webhosting company, reports on trying it out, with mixed feelings. Their opinion: worth a look-in for most systems, but too risky for frontline production servers. The writeup includes a few nasty caveats that will bite you on serious deployments."
o2binbuzios writes "Due to an office move, I have a chance to do a clean-sheet design for an integration room at a fairly large VAR ($100M+ ). I'm looking for some ideas or best practice to support 100-120 square meters (~50 x 30 ft). I'm particularly interested in ideas around efficient workflow, ways to manage cabling and electrical, and 'environmental' solutions that make it a pleasant place to work. There will be a central bench with 6-8 stations (3-4 per side) with engineers and techs who may be configuring stacks of up to 10 devices at a time that could range from servers, to network elements, to SAN & NAS devices and more. I've been looking for a paper that seems like it must exist — but I'm happy to gather good ideas one at a time or in bunches here on Slashdot."
concealment writes "Sparkler Filters up north in Conroe [Texas] still uses an IBM 402 in conjunction with a Model 129 key punch – with the punch cards and all – to do company accounting work and inventory. The company makes industrial filters for chemical plants and grease traps. Lutricia Wood is the head accountant at Sparkler and the data processing manager. She went to business school over 40 years ago in Houston, and started at Sparkler in 1973. Back then punch cards were still somewhat state of the art." See kottke.org for an eye-popping view of one of the "programs" — imagine debugging that.
coondoggie writes "When it comes to fixing broken systems, especially in remote locations, engineers could soon turn to a new mobile robotic system IBM is developing that could help them more easily find the broken equipment, offer up information about the system and provide real-time visual support from supervising experts. The mobile maintenance, repair and operations prototype includes an application that lets a supervisor monitor an engineer's progress towards the maintenance site, and a robotic arm coupled with a camera system, a microphone and laser pointer."
