jjslash writes: An article at TechSpot tests how much RAM you need for regular desktop computing and how it affects performance in apps and games. As it turns out, there's not much benefit going beyond 8 GB for regular programs, and surprisingly, 4GB still seems to be enough for gaming in most cases. Although RAM is cheap these days, and they had to go to absurdly unrealistic settings to simulate high demand for memory outside of virtualization, it's a good read to confirm our judgment calls on what is enough for most in 2015.

In recent testing it was confirmed that Intel's Skylake-based Core i7-6700K is the company's fastest quad-core desktop processor to date. However, one thing Intel kept a tight lid on was the underlying technology of the Gen9 Intel HD Graphics engine on board Skylake, that is until now. An overview of the changes Intel made specific to Intel Gen9 graphics, notes the following among other tweaks: Available L3 cache capacity has been increased to 768 Kbytes per slice (512 Kbytes for application data). Sizes of both L3 and LLC request queues have been increased. This improves latency hiding to achieve better effective bandwidth against the architecture peak theoretical. Gen9 EDRAM now acts as a memory-side cache between LLC and DRAM. Also, the EDRAM memory controller has moved into the system agent, adjacent to the display controller, to support power efficient and low latency display refresh. Gen9 has also been designed to enable products with 1, 2, or 3 slices, each with 24 EUs per slice and 8 EUs per subslice. Finally, Gen9 adds new power gating and clock domains for more efficient dynamic power management. This can particularly improve low power media playback modes.

This debate started out with a post from Tom Jennings who is known as the creator of Fidonet but works a lot with electronic hardware. Adam Fabio — himself an Electronics Engineer — picked up on the argument for the other side. He attests that if used in the proper application these parts are second to none.

Vigile writes: The future of graphics APIs lies in DirectX 12 and Vulkan, both built to target GPU hardware at a lower level than previously available. The advantages are better performance, better efficiency on all hardware and more control for the developer that is willing to put in the time and effort to understand the hardware in question. Until today we have only heard or seen theoretical "peak" performance claims of DX12 compared to DX11. PC Perspective just posted an article that uses a pre-beta version of Ashes of the Singularity, an upcoming RTS utilizing the Oxide Games Nitrous engine, to evaluate and compare DX12's performance claims and gains against DX11. In the story we find five different processor platforms tested with two different GPUs and two different resolutions. Results are interesting and show that DX12 levels the playing field for AMD, with its R9 390X gaining enough ground in DX12 to overcome a significant performance deficit that exists using DX11 to the GTX 980.

The project is only available in San Francisco, Boston, and Fresno for now. Techcrunch reports: "To get started, you simply plug in your address and some data about your monthly electricity bill, and the tool will tell you what the recommended solar installation size is and how much it would cost to buy or lease the hardware. In case you want to go ahead with a solar install, the tool also lets you reach out to local solar providers. Google says these listings are sponsored, so chances are it'll get a bit of a kickback when it generates a sales lead for these companies."

"The idea is that those companies participating in this project can work together, and begin building a set of open source tools and technologies for Linux mainframes, while helping one another overcome common development issues in the same manner as all open source projects." IBM's hardware release is accompanied by 250,000 lines of code that they're open sourcing as well. "Ultimately the mainframe mainstays are hoping to attract a new generation of developers to their platform. To help coax new users, IBM will be offering free access to the LinuxOne cloud, a mainframe simulation tool it developed for creating, testing and piloting Linux mainframe applications." Canonical is working with IBM to bring Ubuntu to mainframes.

An anonymous reader writes: Google recently reiterated their commitment to the goal of a $50 smartphone in India, and a new article breaks down exactly what that means for the phone's hardware. A budget display will eat up about about $8 of that budget — it's actually somewhat amazing that so little money can still buy a 4-4.5" panel running at 854x480. For another $10, you can get a cheap SoC — something in the range of 1.3Ghz and quad-core, complete with Wi-Fi, Bluetooth, and GPS radios. A gigabyte of RAM and 4 gigabytes of storage can be had for another $10 or so. Throw in a $2.10, 1,600 mAh battery and a $5 camera unit, and you've got most of a phone. That leaves about $9 to play with for basic stuff like a casing, and then packaging/marketing costs (some of which could be given freely, like the design work.) Profit margins will be nonexistent, but that's less of an issue for Google, who simply wants to spread the reach of Android.

schwit1 sends news that researchers from the University of Cambridge have developed robots that emulate natural selection. The "mother" robot designs and builds its "child" bots, and then tests them against particular criteria. The child bots that are the most successful have their traits carried on to the next generation. "For each robot child, there is a unique ‘genome’ made up of a combination of between one and five different genes, which contains all of the information about the child’s shape, construction and motor commands. As in nature, evolution in robots takes place through ‘mutation’, where components of one gene are modified or single genes are added or deleted, and ‘crossover’, where a new genome is formed by merging genes from two individuals." By the final generation, the fastest robots were able to perform their task twice as fast as the average robot in the first generation.

MojoKid writes: Will they or won't they continue on with the 'flat tire' display? That's been the big question surrounding Motorola's next generation Moto 360 smartwatch. Today, we finally learn the answer to the question, and unfortunately, it looks as though Motorola still hasn't seen clear to incorporate a completely circular display like LG, Huawei and now Samsung into a smartwatch. In an incredibly short video posted to Motorola's official Twitter account (the tweet has since been taken down), we see a fleeting glimpse of the next generation Moto 360. There is still a cutout at the bottom of the display, which houses an ambient light sensor in the current generation Moto 360. Keen eyes will also spot that the side button has been moved from the 3 o'clock position to the 2 o'clock position and that the integrated lug system for the watch bands has been abandoned in favor of an external lug system typical of most modern wristwatches.

The company that actually owns the mark, Commodore Holdings, is not amused. It's not like it would have been hard to determine who owns it and try to license. The C= Holdings trademark is registered with the same EU agency 'CBM Limited' applied for a new mark. I can't see much of an excuse here. The company holding Commodore's trademarks is literally Commodore Holdings. They can't even say "We had NO IDEA who to contact!"

Think of C.H.I.P as a tablet computer that runs Linux instead of Android, "without the tablet bits," says interviewee Dave, who gave a talk -- which was mostly live demos -- at OSCON 2015. 50,000 C.H.I.P.s have already sold for $9 through their successful Kickstarter campaign, and Next Thing Co. plans to stick with the $9 price for the foreseeable future -- plus add-on boards (that they call "shields") they hope to sell you, but that won't flatten any but the skinniest wallets; given the projected price scale, you'll have trouble spending as much as $50 for a fully-accessorized C.H.I.P. unit.

"But," you may ask, "is C.H.I.P. Open Source?" You bet! No hedging here, just flat-out Open Source, from the bottom to the top, with all software (and hardware specs) freely available via GitHub. And lastly, the "I'll Be Your $9 Computer Today' statement in the headline above is allegorical, not factual. We've seen projected shipping dates for C.H.I.P ranging from "by the end of 2015" to a simple "2016." Either way, we're waiting with bated breath.

Charge-as-you-drive technologies have already been used in the South Korean town of Gumi. The town has a 12km (7.5 miles) route that allows buses to be charged as they drive over it. In a press release the agency says: "The trials are expected to begin later this year following the completion of an ongoing procurement process. The trials will involve fitting vehicles with wireless technology and testing the equipment, installed underneath the road, to replicate motorway conditions. Full details of the trials will be publicised when a successful contractor has been appointed."

Dave Knott writes with news that US regulators have given iRobot clearance to make and sell an unmanned lawn mower. The company, known for its robot vacuum cleaner Roomba, has designed a robot lawn mower that would wirelessly connect with stakes in the ground operating as signal beacons, rising above the ground by as much as 61 centimetres. The Federal Communications Commission usually prohibits the operation of "fixed outdoor infrastructure" transmitting low-power radio signal without a licence. iRobot's lawn mower beacons fall in that category, and the stake design required a waiver from the FCC, which was opposed by the National Radio Astronomy Observatory, stating that the lawn mowers would interfere with its telescopes.

An anonymous reader writes: Samsung's announcement today of the Galaxy Note 5 and Galaxy S6+ was a disappointment to a lot of power users. The phones both use a 3,000 mAh, non-removable battery. This is presumably part of Samsung's quest for thinner and thinner phones, but it's bad news for those who prize function over form — particularly from a phone line that is ostensibly made for power users. So, those of you who have the pulse of the mobile industry: what's my best bet for a high end phone that doesn't compromise on battery life? Are there any devices on the horizon that are likely to have big batteries? I'm also wondering if I should just get a cheap phone to tide me over to the next generation of flagships. My current device is old and doesn't have the fast/quick-charge tech that modern ones do — does that work as advertised?

ckwu writes: The designs of pacemakers, watches, and other wearable gadgets have to be tailored around existing battery shapes, such as cylinders, coin cells, and rectangles. But a team of researchers hopes their fully printable, flexible lithium-ion batteries will one day free designers from these constraints. Battery shapes are now limited because of the need to contain liquid electrolytes. Two years ago, the researchers designed a printable, solid-state electrolyte composed of alumina nanoparticles and lithium combined with polymer that can be cured by ultraviolet light. In this latest work, they used a stencil printing technique to print full battery cells with the electrolyte and other printable materials for the electrodes. They printed batteries on paper and the curved surface of a glass mug. These printed Li-ion batteries can power small LEDs but still need a lot of improvements because they don't last long before needing recharging.

MojoKid writes: Sometimes it's the enterprise sector that gets dibs on the coolest technology, and so it goes with a trio of TCO-optimized, high-performance solid state drives from Samsung that were just announced, all three of which are based on three-dimensional (3D) Vertical NAND (V-NAND) flash memory technology. The fastest of bunch can read data at up to 5,500 megabytes per second. That's the rated sequential read speed of Samsung's PM1725, a half-height, half-length (HHHL) PCIe card-type NVMe SSD. Other rated specs include a random read speed of up to 1,000,000 IOPS, random write performance of up to 120,000 IOPS, and sequential writes topping out at 1,800MB/s. The PM1725 comes in just two beastly storage capacities, 3.2TB and 6.4TB, the latter of which is rated to handle five drive writes per day (32TB) for five years. Samsung also introduced two other 3D V-NAND products, the PM1633 and PM953. The PM1633 is a 2.5-inch 12Gb/s SAS SSD that will be offered in 480GB, 960GB, 1.92TB, and 3.84TB capacities. As for the PM953, it's an update to the SM951 and is available in M.2 and 2.5-inch form factors at capacities up to 1.92TB.

An anonymous reader writes: One of the biggest problems virtual reality headsets have yet to overcome is the headaches they cause in a subset of users. For a lot of users, this is caused by needing to rapidly switch your focus between objects that are (virtually) near and far away. "Trying to focus on 'far away' objects on that stereoscopic screen means keeping a fixed focal distance but changing the 'vergence' angle of your eyes—in essence, going a little cross-eyed for a moment." Fortunately, researchers at Stanford have figured out a partial solution.

They "created a prototype headset (PDF) that includes a translucent LCD panel sitting about 1cm in front of a standard, opaque LCD. With some GPU pre-processing, this 'light field stereoscope' headset can display nearby objects on the front LCD and farther-away objects on the rear, creating what the researchers call a '4D' image that layers a basic virtual light field on top of the usual stereoscopic left/right eye 3D separation." This provides an easy, low-tech way to let the eyes focus more easily, and alleviate the strain that causes headaches.
