On-Chip Liquid Cooling Permits Smaller Devices With No Heatsinks Or Fans

An anonymous reader writes: DARPA-funded research into on-chip liquid cooling has resulted in a field-programmable gate array (FPGA) liquid-cooled device that can operate at 24 degrees Celsius, versus 60 degrees Celsius for an equivalent air-cooled device. The cooling fluid resides only nanometers from the heat it must address, and operates so efficiently as to offer potential to stack CPUs and GPUs using copper columns, as well as dispensing with heat-sinks and fan systems. With those components removed, the system can facilitate far more compact designs than are currently feasible. Read more of this story at Slashdot.

Android 6.0 Marshmallow, thoroughly reviewed

(credit: Ron Amadeo) After a lengthy developer preview , the newest version of Google’s flagship operating system is finally ready for the masses. Android 6.0 Marshmallow is the 23rd version of Google’s “mobile” operating system, though it can accurately be described as “mobile” only if you’re referring to how much it gets around. With all the areas in which Google now tinkers, Marshmallow is destined for smartphones, tablets, watches, televisions, and cars, among others. Google says that the new release has a “back to basics” motif with a focus on “polish and quality.” Marshmallow makes many long-requested features a reality with selectable app permissions, a data backup system that actually works, and the ability to format SD cards as Ext4, allowing the system to treat cards just like internal storage. Marshmallow is also prepared for the future with support for USB Type-C’s power delivery spec, a Fingerprint authentication API, and 4K display support. And, as with any Android release, there’s also lots of new Googley stuff—a slick new search interface and a contextual search mode called “Google Now on Tap,” for example. While this is a review of the final build of “Android 6.0,” we’re going to cover many of Google’s apps along with some other bits that aren’t technically exclusive to Marshmallow. Indeed, big chunks of “Android” don’t actually live in the operating system anymore. Google offloads as much of Android as possible to Google Play Services and to the Play Store for easier updating and backporting to older versions, and this structure allows the company to retain control over its open source platform. As such, consider this a look at the shipping Google Android software package rather than just the base operating system. “Review: New Android stuff Google has released recently” would be a more accurate title, though not as catchy.

Newly Found TrueCrypt Flaw Allows Full System Compromise

itwbennett writes: James Forshaw, a member of Google’s Project Zero team has found a pair of flaws in the discontinued encryption utility TrueCrypt that could allow attackers to obtain elevated privileges on a system if they have access to a limited user account. ‘It’s impossible to tell if the new flaws discovered by Forshaw were introduced intentionally or not, but they do show that despite professional code audits, serious bugs can remain undiscovered, ‘ writes Lucian Constantin.

GCHQ Tried To Track Web Visits of "Every Visible User On Internet"

An anonymous reader writes with Ars Technica’s story on the relevations reported today by The Intercept that the UK’s GCHQ has been tracking World Wide Web users since 2007, with an operation called “Karma Police” — “a program that tracked Web browsing habits of people around the globe in what the agency itself billed as the ‘world’s biggest’ Internet data-mining operation, intended to eventually track ‘every visible user on the Internet.'” Read more of this story at Slashdot.

Dr Who Detective Philip Morris Hints At More Rediscovered Episodes

BigBadBus writes: In late 2013, Philip Morris announced that he had found 9 missing episodes of 1960s Dr.Who, which completed the 1968 story “Enemy of the World” and most of “The Web of Fear.” He has now gone on record to talk about the only episode of these stories that he didn’t find — namely part 3 of “Web of Fear” and teases of more episode finds to come. Episodes keep trickling out of the past, it seems; we’ve mentioned a few small finds in 2004 and 2011, too. Read more of this story at Slashdot.

Light-Based Memory Chip Is First To Permanently Store Data

sciencehabit writes: Scientists have developed the first ever memory chip that’s entirely light-based and can store data permanently. Sciencemag reports: “Today’s electronic computer chips work at blazing speeds. But an alternate version that stores, manipulates, and moves data with photons of light instead of electrons would make today’s chips look like proverbial horses and buggies. Now, one team of researchers reports that it has created the first permanent optical memory on a chip, a critical step in that direction. If a more advanced photonic memory can be integrated with photonic logic and interconnections, the resulting chips have the potential to run at 50 to 100 times the speed of today’s computer processors.” Read more of this story at Slashdot.

iPhone 6s’s A9 Processor Racks Up Impressive Benchmarks

MojoKid writes: Underneath the hood of Apple’s new iPhone 6s and iPhone 6s Plus models is a new custom designed System-on-Chip (SoC) that Apple has dubbed its A9 processor. It’s a 64-bit chip that, according to Apple, is the most advanced ever built for any smartphone, and that’s just one of many claims coming out of Cupertino. Apple is also claiming a level of gaming performance on par with dedicated game consoles and with a graphics engine that’s 90 percent faster than the previous generation. For compute chores, Apple says the A9 chip improves overall CPU performance by up to 70 percent. These performance promises come without divulging too much about the physical makeup of the A9, though in testing its dual-core SoC does seem to compete well with the likes of Samsung’s octal-core Exynos chips found in the Galaxy S6 line. Further, in intial graphics benchmark testing, the A9 also leads the pack in mosts tests, sometimes by a healthy margin, even besting Qualcomm’s Snapdragon 810 in tests like 3DMark Ice Storm Unlimited.

Mozilla Fixed a 14-Year-Old Bug In Firefox, Now Adblock Plus Uses Less Memory

An anonymous reader writes: Mozilla launched Firefox 41 yesterday. Today, Adblock Plus confirmed the update “massively improves” the memory usage of its Firefox add-on. This particular memory issue was brought up in May 2014 by Mozilla and by Adblock Plus. But one of the bugs that contributed to the problem was actually first reported on Bugzilla in April 2001 (bug 77999). Read more of this story at Slashdot.

Study: People Emit a "Germ Cloud" of Bacteria As Unique As a Fingerprint

An anonymous reader writes: According to a new study, we are all surrounded by a personal “germ cloud” as unique as a fingerprint. Lead author of the study Dr James Meadow says: “We expected that we would be able to detect the human microbiome in the air around a person, but we were surprised to find that we could identify most of the occupants just by sampling their microbial cloud. Our results confirm that an occupied space is microbially distinct from an unoccupied one, and demonstrate for the first time that individuals release their own personalized microbial cloud.” The findings were published today in the journal PeerJ.

NVIDIA Announces GeForce GTX 980 GPU For High-End Gaming Notebooks

MojoKid writes: NVIDIA is taking things is a slightly different direction today, at the ultra-high-end of their mobile graphics offering, introducing a “new” mobile GPU implementation, that’s not really a mobile part at all, the GeForce GTX 980. Notice, there’s no “M” on the end of that model number. NVIDIA is betting that the enthusiasts that are most likely to buy a notebook with a GeForce GTX 980 in it are savvy enough to understand the difference. Through some careful binning and optimization of the components that accompany the GPU, including the memory, voltage regulation module, and PCB, NVIDIA was able to take the full desktop GeForce GTX 980 GPU and cram it into mobile form factors. The mobile flavor of the GeForce GTX 980 features selectively binned GPUs that are able to achieve high frequencies at lower-than-typical voltages. And those GPUs are paired to 7Gbps GDDR5 memory and a heat sink with up to 2X the capacity of typical solutions. Notebooks powered by this GPU will be unlocked, and fully overclockable.The performance of the GeForce GTX 980 will also allow notebooks powered by the GPU to push multiple screens or power VR gear. NVIDIA was demoing a GTX 980-powerd Clevo notebook at an event in New York, connected to a trio of 1080P monitors, running GTA V at smooth framerates. Read more of this story at Slashdot.
