MrSeb writes "Two doctors at Penn State University have developed Caffeine Zone, a free iOS app that tells you the perfect time to take a coffee break to maintain an optimal amount of caffeine in your blood — and, perhaps more importantly, it also tells you when to stop drinking tea and coffee, so that caffeine doesn't interrupt your sleep. By reading through lots of peer-reviewed studies, doctors Frank E. Ritter and Kuo-Chuan Yeh found that a caffeine level of between 200 and 400mg in your bloodstream provides optimal mental alertness, and that you should be below 100mg when you try to sleep. Caffeine Zone plots your caffeination level after you consume caffeine, and warns you if that big afternoon coffee will keep you up at night. It also lets you change the 'optimal' and 'sleep' values if you're particularly resistant or weak to caffeine."

MrSeb writes "In an 8,000-word treatise, Steven Sinofksy himself has taken up pen and paper to describe Windows 8 on ARM (WOA) in great detail. There's a lot of good stuff in there, but one point is particularly troubling. Quoting Sinofsky: 'WOA does not support running, emulating, or porting existing x86/64 desktop apps. Code that uses only system or OS services from WinRT can be used within an app and distributed through the Windows Store for both WOA and x86/64. Consumers obtain all [WOA] software, including device drivers, through the Windows Store and Microsoft Update or Windows Update.' It's hard to under-emphasize just how huge a change that is. It's one thing to say that ARM CPUs won't support x86 emulation; something else entirely to split software delivery and installation. Up until now, one of the biggest differences between desktop and mobile operating systems has been the ability to install software. It's true that Microsoft's decision to wall off unapproved software installation is similar to the approach of Android and iOS — but iOS isn't the same thing as OS X. Combining both of these decisions under the 'Windows' brand could be disastrous, not because Microsoft is evil, but because it creates two entirely different user experiences on the basis of which ISA your CPU supports."

MrSeb writes with this selection from ExtremeTech: "Why doesn't Google offer a cloud storage service to rival Dropbox, Box.net, or Microsoft's SkyDrive? Google has the most internet-connected servers in the world, the largest combined storage of any web company, and already offers photo storage (Picasa), document storage (Docs), music storage (Music), but for some reason it has never offered a unified Google Drive. According to people familiar with the matter, however, our wait is almost over: Google's Hard Drive In The Sky is coming soon, possibly 'within weeks.' Feature-wise, it sounds like Google Drive will be comparable to Dropbox, with free basic storage (5GB?) and additional space for a yearly fee."

MrSeb writes "Hold onto your hats: Scientists at the University of York, England have completely rewritten the rules of magnetic storage (abstract; full paper paywalled). Instead of switching a magnetic region using a magnetic field (like a hard drive head), the researchers have managed to switch a ferrimagnetic nanoisland using a 60-femtosecond laser. Storing magnetic data using lasers is up to 1,000 times faster than writing to a conventional hard drive (we're talking about gigabytes or terabytes per second) — and the ferrimagnetic nanoislands that store the data are capable of storage densities that are some 15 times greater than existing hard drive platters. Unfortunately the York scientists only detailed writing data with lasers; there's no word on how to read it."

MrSeb writes "There are around 100 billion neurons in a human brain, forming up to 100 trillion synaptic interconnections. Neuroscientists believe that these synapses are the key to almost every one of your unique, identifiable features: Memories, mental disorders, and even your personality are encoded in the wiring of your brain. Understandably, neuroscientists really want to investigate these neurons and synapses to work out how they play such a vital role in our human makeup. Unfortunately, these 100 trillion connections are crammed into a two-pound bag of soggy flesh, making analysis rather hard. Starting small and working its way up, MIT today launched Eyewire, a crowdsourced 'game' that tasks users with wiring up the neurons in a mouse's retina. A future stage of the game will get users to find the synapses, too."

MrSeb writes "Thanks to a leaked video — a video that Microsoft made for Nokia — we now have lots of details about Windows Phone 8 (WP8). From deep Windows 8, Skype, and SkyDrive integration, through to the addition of NFC 'wallet' payments and BitLocker encryption, it sounds like Windows Phone 8 will be close to iOS and Android in terms of features. The interesting stuff is under the hood, though: WP8 will have the Windows 8 kernel instead of the Windows CE kernel of its predecessors. Through the Win 8 kernel, WP8 will support native code and multi-core processors. It will also have the same network stack, security, and multimedia support as Windows 8. While Win 8 apps won't be directly compatible with Windows Phone 8, Windows Phone manager Joe Belfiore says developers will be able to 'reuse — by far — most of their code.'"

MrSeb writes "You've heard of smart cars, and now, rolling out in San Francisco, is a smart parking system that promises to eliminate the arduous process of finding a parking spot. SFpark is a network of magnetic sensors that have been installed under 8,200 street parking spaces, along with additional information from parking garages and parking meters. These sensors are all linked together in a mesh network, and ultimately link back to a central command center. Drivers can access this parking data via the SFpark website or smartphone app, and see in real-time where parking spaces are available. At any one time, a third of cars on the road in urban areas are looking for parking spots, consuming more fuel, creating more pollution, and causing more accidents. With SFpark, you can see at a glance where there's a parking spot — but in the future, you'll be able to hit a button and have your smartphone direct you to the nearest parking spot."

MrSeb writes "Since Slashdot first covered lovotics back in July 2011, its creator — Hooman Samani — has been busy working on a couple of new applications for his fledgling scientific sphere of human-robot love: Kissenger and Mini-Surrogate. Kissenger is a robot with highly-sensitive and motor-actuated lips, which you can use to transmit a kiss to another Kissenger robot (held by a friend or loved one) over the internet. Mini-Surrogate is basically a real-world avatar that adds a physical element to video conferencing. Both are primarily for human-human use, but it's easy to imagine a Kissenger hooked up to an AI or video game. Likewise, the next Elder Scrolls game could come with a Mini-Surrogate, so that you can communicate with your in-game wife while you're knee-deep in fireballed orc."

MrSeb writes "In a world where warfare is fast becoming fielded by remote controlled and autonomous robots, innovation is the key to victory. The most technologically advanced superpower can see more, plan better, and attack from further away than its inferior adversaries. What better way to revolutionize the drone and robotics industry than use the brilliant minds of our children? That's what DARPA and the Defense Department's research and development arm thinks, anyway. The Manufacturing Experimentation and Outreach Initiative, part of the Adaptive Vehicle Make project, is slated to reach a thousand schools in and out of the country, roping in the brightest minds to develop robotics and advance technology in new and interesting ways. Funded by the Department of Defense, the program comes with a steep cost: The DoD wants unlimited rights to everything the students build. It sounds almost like something Orson Scott Card would dream up."

MrSeb writes "An Italian researcher with a penchant for retro games — or perhaps just looking for an excuse to play games in the name of science! — has used computational complexity theory to decide, once and for all, just how hard video games are. In a truly epic undertaking, Giovanni Viglietta of the University of Pisa has worked out the theoretical difficulty of 13 old games, including Pac-Man, Doom, Lemmings, Prince of Persia, and Boulder Dash. Pac-Man, with its traversal of space, is NP-hard. Doom, on the other hand, is PSPACE-hard."

MrSeb writes "After more than five years in the pipeline, Mozilla Labs and the Rust community have released the first alpha of the Rust programming language compiler. The Rust language emphasizes concurrency and memory safety, and — if everything goes to plan — is ultimately being groomed to replace C++ as Mozilla's compiled language of choice, with Firefox (or parts of it) eventually being re-written in Rust."

MrSeb writes "Researchers from Imperial College London and A*STAR in Singapore have shown off a terahertz antenna that's just 100 nanometers across — about 30,000 times smaller than existing terahertz antennae — and two orders of magnitude stronger than other T-ray beam-forming techniques. T-rays are a lot like EHF (extremely high frequency), which is used by millimeter wave scanners in airports, medical imaging, and emerging wireless networking standards like WiGig — but stronger, faster, and more detailed. Where EHF radiation can see through your clothes, T-rays can penetrate a few millimeters of skin. Furthermore, because atoms and molecules have a unique terahertz-range signature, T-ray scanners can detect toxic substances, bombs, drugs — or even cancerous tumors under your skin. Most importantly, though, due to the nano scale of these antennae, it's possible to create huge antennae arrays on a single silicon chip, meaning hand-held T-ray scanners are now a possibility. In the not so distant future, every household might have a Star Trek-like tricorder capable of detecting cancer or other diseases."

MrSeb writes "Megaupload's shutdown poses an interesting question: What happens to all the files that were stored on the servers? XDA-Developers, for example, has more than 200,000 links to Megaupload — and this morning, they're all broken, with very little hope of them returning. What happens if a similar service, like Dropbox, gets shut down — either through bankruptcy, or federal take-down? Will you be given a chance to download your files, or helped to migrate them to another similar service? What about data stored on enterprise services like Azure or AWS — are they more safe?" And if you're interested, the full indictment against Megaupload is now available.

adeelarshad82 writes "After years of promises to enter the smartphone market, Intel has finally done so. During his keynote at CES, Intel's Chief executive Paul Otellini said that Intel has signed Lenovo and Motorola to contracts to use its Atom processors in smartphones. Unlike past launches, Intel has held Medfield back until its partners were ready to go to press as well. According to an early preview, Medfield pairs a 1.6GHz Atom CPU with an SGX540 GPU designed by PowerVR. This is the same GPU we've seen tip up in the Samsung Galaxy Nexus and Droid Razr, though Intel is clocking it higher, at 400MHz. Intel's new SoC encodes video at 720p at 30 fps, can playback 1080p at 30 fps, and supports 1920×1080 output via HDMI. The first smartphone to carry an Intel chip will debut on China Unicom during the second quarter."

MrSeb writes with a piece on Google's renewed push for Google TV adoption. From the article: "In spite of a mediocre launch caused by an overpriced device and low consumer adoption, Mountain View is attempting to breathe life into Google TV in the way of a major marketing push at CES 2012. By announcing partnerships with companies like Marvell and LG, and an effort to cut costs by switching to ARM architecture, Google is hoping to finally achieve the mass adoption it has been hoping for with the service. Is this a case of too little, too late?"

MrSeb writes "Microsoft, in its infinite wisdom, will provide push-button Reset and Refresh in Windows 8. Reset will restore a Windows 8 PC to its stock, fresh-from-the-factory state; Refresh will reinstall Windows 8, but keep your documents and installed Metro apps in tact. For the power users, Windows 8 will include a new tool called recimg.exe, which allows you to create a hard drive image that Refresh will use (you can install all of your Desktop apps, tweak all your settings, run recimg.exe... and then, when you Refresh, you'll be handed a clean, ready-to-go computer). Reset and Refresh are obviously tablety features that Windows 8 will need to compete against iOS and Android — but considering Windows' malware magnetism and the number of times I've had to schlep over to my mother's house with a Windows CD... these features should be very welcome on the desktop, too."

MrSeb writes with this excerpt from an Extreme Tech article about the latest FreeDOS release and a bit of project history: "Some 17 years after its first release in 1994, and more than five years since 1.0, FreeDOS 1.1 is now available to download. The history of FreeDOS stems back to the summer of 1994 when Microsoft announced that MS-DOS as a separate product would no longer be supported. It would live on as part of Windows 95, 98, and (ugh!) Me, but for Jim Hall that wasn't enough, and so public domain (PD) DOS was born. ... Despite what you might think, FreeDOS isn't an 'old' OS; it's actually quite usable. FreeDOS supports FAT32, UDMA for hard drives and DVD drives, and it even has antivirus and BitTorrent clients." The official release announcement has more details on the improvements, and the FreeDOS website has the release for download.

MrSeb writes "Taylor Valtrop, an enterprising roboticist with a penchant for kitties, has crafted the mother of all Kinect (and Wiimote!) hacks: The teleoperation of a robot to groom a cat. Using a Nao, a $15,000 robot; a treadmill (for moving the robot forward); a head-mounted display (to see what the robot sees); Kinect (for tracking his movements); and two Wiimotes (to move the robot's hands), Valtrop is able to pat a cat with surprising accuracy and gentleness (except for where he accidentally hits the cat in the face)."

MrSeb writes "For the last six months, orangutans — those great, hairy, orange apes that go 'ook' a lot — at Milwaukee Zoo have been playing games and watching videos on Apple's iPad, but now their keepers and the charity Orangutan Outreach want to go one step further and enable ape-to-ape video chat via Skype or FaceTime. 'The orangutans loved seeing videos of themselves — so there is a little vanity going on — and they like seeing videos of the orangutans who are in the other end of the enclosure,' Richard Zimmerman of Orangutan Outreach said. 'So if we incorporate cameras, they can watch each other.' And thus the idea of WiFi video chat between orangutans — and eventually between zoos — was born. It might seem like folly, but putting (ruggedized!) iPads into the hands of apes could really revolutionize our understanding of great ape behavior."

MrSeb writes "Altering the very fabric of technophilic society, a multinational team of material scientists have created electric circuits and transistors out of cotton fibers (abstract). Two kinds of transistor were created: a field-effect transistor (FET), much like the transistors found in your computer's CPU; and an electrochemical transistor, which is similar but capable of switching at lower voltages, and thus better suited for wearable computers. Cotton itself is an insulator, but by using various coatings, the team from Italy, France, and the United States was able to make conductor and semiconductor cotton 'wires' that retained most of their flexibility. The immediate use-cases are clothes with built-in sensors (think radiation or heartbeat monitors), but ultimately, think of how many thousands of interconnections are in every piece of cotton clothing — you could make a fairly powerful computer!"

MrSeb writes "Specifications and benchmarks of Intel's 32nm Medfield platform — Chipzilla's latest iteration of Atom and first real system-on-a-chip oriented for smartphones and tablets — have leaked. The tablet reference platform is reported to be a 1.6GHz x86 CPU coupled with 1GB of DDR2 RAM, Wi-Fi, Bluetooth, and FM radios, and an as-yet-unknown GPU. The smartphone version will probably be clocked a bit slower, but otherwise the same. Benchmark-wise, Medfield seems to beat the ARM competition from Samsung, Qualcomm, and Nvidia — and, perhaps most importantly, it's also in line with ARM power consumption, with an idle TDP of around 2 watts and load around 3W."

MrSeb writes "At this point we have a fairly good idea of what Carrier IQ is, and which manufacturers and carriers see fit to install it on their phones, but the Electronic Frontier Foundation — the preeminent protector of your digital rights — has taken it one step further and reverse engineered some of the program's code to work out what's actually going on. There are three parts to a Carrier IQ installation on your phone: The program itself, which captures your keystrokes and other 'metrics'; a configuration file, which varies from handset to handset and carrier to carrier; and a database that stores your actions until it can be transmitted to the carrier. It turns out that that the config profiles are completely unencrypted, and thus very easy to crack."

MrSeb writes "According to new research from HTTP Archive, which regularly scans the internet's most popular destinations, the average size of a single web page is now 965 kilobytes, up more than 30% from last year's average of 702KB. This rapid growth is fairly normal for the internet — the average web page was 14KB in 1995, 93KB by 2003, and 300KB in 2008 — but by burrowing a little deeper into HTTP Archive's recent data, we can discern some interesting trends. Between 2010 and 2011, the average amount of Flash content downloaded stayed exactly the same — 90KB — but JavaScript experienced massive growth from 113KB to 172KB. The amount of HTML, CSS, and images on websites also showed a significant increase year over year. There is absolutely no doubt that these trends are attributable to the death throes of Flash and emergence of HTML5 and its open web cohorts." If you have a personal home page, how big is it?

MrSeb writes "Earlier this week, an ExtremeTech writer received a press release from a Romanian overclocking team that smashed a few overclocking records, including pushing Kingston's HyperX DDR3 memory to an incredible 3600MHz (at CL10). The Lab501 team did this, and their other record breakers, with the aid of liquid nitrogen which cooled the RAM down to a frosty -196C. That certainly qualifies as extreme, but is it news? Ten years ago, overclocking memory involved a certain amount of investigation, research, and risk, but in these days of super-fast RAM and manufacturer's warranties it seems a less intoxicating prospect. As it becomes increasingly difficult to justify what a person should overclock for, has the enthusiast passion for overclocking cooled off?"

MrSeb writes "A crack team of engineers at the University of Illinois has developed an electronic circuit that autonomously self-heals when its metal wires are broken. This self-healing system restores conductivity within 'mere microseconds,' which is apparently fast enough that operation can continue without interruption. The self-healing mechanism is delightfully simple: The engineers place a bunch of 10-micron (0.01mm) microcapsules along the length of a circuit. The microcapsules are full of liquid metal, a gallium-indium alloy, and if the circuit underneath cracks, so do the microcapsules (90% of the time, anyway — the tech isn't perfect yet!). The liquid metal oozes into the circuit board, restoring up to 99% conductivity, and everything continues as normal. This even works with multi-layer printed circuit boards (PCBs), such the motherboard in your computer, too. There's no word on whether this same technology could one day be used by Terminators to self-heal shotgun blasts to the face, but it certainly sounds quite similar. The immediate use-cases are in extreme environments (aerospace), and batteries (which can't be taken apart to fix), but long term we might one day buy motherboards with these self-healing microcapsules built in."

MrSeb writes "Firefox 9 is now available — but unlike its previous rapid release forebears where not a lot changed, a huge feature has landed with the new version: the JavaScript engine now has type inference enabled. This simple switch has resulted in a 20-30% JS execution speed increase (PDF), putting JaegerMonkey back in line with Chrome's V8 engine, and even pulling ahead in some cases. If you switched away from Firefox to IE or Chrome for improved JS performance, now is probably the time to give Firefox another shot."

MrSeb writes "In an interesting move that should finally bring the United States' fast-and-loose advertising rules and regulations into line with the UK and EU, the National Advertising Division (NAD) — the advertising industry's self-regulating watchdog — has moved to ban the misleading use of photoshopping and enhanced post-production in cosmetics adverts. The ban stems from a Procter & Gamble (P&G) CoverGirl ad that photoshopped a model's eyelashes to exaggerate the effects of a mascara. There was a footnote in the ad's spiel about the photo being manipulated, but according to the director of the NAD, that simply isn't enough: 'You can't use a photograph to demonstrate how a cosmetic will look after it is applied to a woman's face and then — in the mice type — have a disclosure that says "okay, not really."' The NAD ruled that the ad was unacceptable, and P&G has since discontinued it. The ruling goes one step further, though, and points out that 'professional styling, make-up, photography and the product's inherent covering and smoothing nature' should be enough, without adding Photoshop to the mix. The cosmetics industry is obviously a good starting point — but what if the ban leaks over to product photography (I'm looking at you, Burger King), video gameplay demos, or a photographer's own works?"

First time accepted submitter probain writes "MIT has made a camera that can take trillion frames per second! With this high speed capability, they can actually see the movement of photons of light across a scene or object. This is just mind-boggling." ExtremeTech has a nice video of the system, too. What would you like to see slowed down to such a degree?

MrSeb writes "Some interesting legalese found in the recent publication of the Windows Store Application Developer Agreement could signify a very big win for the open source community. The section in question states that apps released under a license from the Open Source Initiative (GPL, Apache, etc.) can be distributed in the Windows Store. Further, it says that the OSI license will trump the Microsoft Standard Application License Terms, namely the the restriction on sharing applications. As for the reasoning behind this big about-turn, it could be down to Microsoft trying to soften the blow of its Android patent litigation — or maybe Redmond is just trying to differentiate itself from Apple, which famously restricts open source-licensed apps from being sold in its iOS and Mac App Stores."

MrSeb writes "A team of engineering geniuses from the University of Bristol, England has developed the world's first re-programmable, multi-purpose quantum photonic computer chip that relies on quantum entanglement to perform calculations. With multiple waveguide channels (made from standard silicon dioxide), and eight electrodes, the silicon chip is capable of repeatedly entangling photons. Depending on how the electrodes are programmed, different quantum states can be produced. The end result is two qubits that can be used to perform quantum computing. Most importantly, though, unlike existing quantum photonic setups which require apparatus the size of a 'large dining table,' this new chip is tiny: just 70mm (2.7 inches) by 3mm."

MrSeb writes "IBM's Watson is made of many parts: speech recognition, natural language processing, machine learning, and data mining. All of these factors were perfectly combined to beat Ken Jennings in Jeopardy, and now each of these components are slowly finding their way into other applications. Health plan company WellPoint, for example, is using Watson to investigate patient records to improve diagnosis, and in a self-referential, possibly universe-destroying twist, IBM itself is using Watson to help sell Watson (and other IBM products) to other companies. Now, using Watson's data mining and natural language talents, IBM has created the Strategic IP Insight Platform, or SIIP, a tool that has already scanned millions of medical patents and journals for the sake of improving drug discovery — and in the future, it's easy to see how the same tool could be used to battle patent trolling, too."

MrSeb writes "DARPA has a problem on its hands: Satellites, unmanned drones (UAVs), and myriad other worldwide sensors are now so ubiquitous and omnipotent that the Department of Defense (DOD) doesn't actually know how to make the best use of them. In other words, the hardware is there, but the software isn't. To tackle this particularly tricky issue, DARPA is looking for smartphone app developers to help build 'sophisticated, adaptive applications.' Yes, DARPA wants to give smartphone developers access to the DOD's fleet of Hellfire missile-equipped UAVs. Instead of using a single, remote pilot to fly just one UAV, DARPA imagines 'an app [...] that allows a swarm of small deployed UAVs to be controlled as a single unit (a hive [mind] so to speak).' DARPA also wants app developers to help out with easy-to-use app interfaces, novel uses of smartphone-like sensors (accelerometers, cameras, gyros) — and ultimately, it wants to make a War Market where a soldier can simply log in with his DOD-issued smartphone or tablet and download Angry UAVs, Nuke Ninja, and other battlefield apps."

MrSeb writes with an excerpt from an Extreme Tech article on the Windows 8 release timeline: "...A Microsoft vice president announced that the Windows 8 beta would begin in late February 2012. The beta will be feature-complete and will allow developers to begin listing their apps in the Store. The timing of the beta is curious, and ultimately quite telling. ... The first public build of Windows 8 ... emerged in mid-September 2011; by the time the beta rolls around, it will have been ruminating for more than five months. If we follow the timeline forward — it took 10 months for Windows 7 to go from beta to public release — then it's possible that Windows 8 might arrive just in time for Black Friday 2012, or perhaps not in 2012 at all. Will its late arrival affect its chances of cutting out a swath of the tablet market from Apple and Android? Or will Windows 8 be different enough that it will do well, no matter when it arrives?" In related news, an anonymous reader notes that IDC predicts Windows 8 will be irrelevant to the traditional PC market.

Zocalo writes "In a post to the Nmap Hackers list Nmap author Fyodor accuses Download.com of wrapping a trojan installer (as detected by various AV applications when submitted to VirusTotal) around software including Nmap and VLC Media Player. The C|Net installer bundles a toolbar, changes browser settings, and, potentially, performs other shenanigans — all under the logo of the application the user thought they might have been downloading. Apparently, this isn't the first time they have done this, either."

MrSeb writes "Last weekend, over 12,000 LAN party goers turned up at DreamHack Winter 2011 in Jonkoping, Sweden with a PC under the arm, on their back, or packed carefully in the trunk of their car. Every single attendee is squeezed into just three massive halls — the largest holding 5,000 computers — or four days, only taking brief breaks to sleep or check out one of the many stages (including some of the largest e-sport tournaments of the year). Being the largest LAN party in the world, DreamHack's infrastructure is suitably monumental: it takes days to lay the thousands of cables, and at the heart of the network is tower of Cisco routers that interface with a 120Gbps internet connection provided by Telia."

MrSeb writes with an excerpt from an Extreme Tech story on the recent wild speculation about AMD abandoning x86: "Recent subpar CPU launches and product cancellations have left AMD in an ugly position, but reports that the company is preparing to jettison its x86 business are greatly exaggerated and wildly off base. Yesterday, Mercury News ran a report on AMD's struggles to reinvent itself and included this quote from company spokesperson Mike Silverman: 'We're at an inflection point. We will all need to let go of the old 'AMD versus Intel' mind-set, because it won't be about that anymore.' When we contacted Silverman, he confirmed that the original statement has been taken somewhat out of context and provided additional clarification. 'AMD is a leader in x86 microprocessor design, and we remain committed to the x86 market. Our strategy is to accelerate our growth by taking advantage of our design capabilities to deliver a breadth of products that best align with broader industry shifts toward low power, emerging markets and the cloud.' The larger truth behind Silverman's statement is that no matter what AMD does, it's not going to be 'AMD versus Intel' anymore — it's going to be AMD vs. Qualcomm, TI, Nvidia, and Intel."

MrSeb writes with an article in Extreme Tech about progress toward getting an AOSP build working on the Nexus S. From the article: "Over the past week, ROM Manager extraordinaire Koush has been frantically working on making a working build of CyanogenMod 9 (Ice Cream Sandwich) for the Samsung Nexus S. The custom ROM, which is built purely from the Android Open Source Project, has now reached 'alpha 11.' All major features are present and no significant bugs remain. It's too early to say that the build is ready for prime time or mission-critical work — the final release of CM9 is due in the new year — but it's certainly stable enough for daily use. The most significant feature, if you can call it that, is that Koush's build of ICS is really very smooth — it's as nimble as Gingerbread, if not more so. Unlike the previous, non-CM build that was released last week, this alpha build of CM9 has every feature enabled, including Google Wallet, and setting a mobile data limit. As usual, the custom ROM is pre-rooted, has ROM Manager installed, and absolutely no bloatware. "

MrSeb writes "Rohm, a Japanese semiconductor company, has created a silicon chip and antenna that's currently capable of transmitting 1.5Gbps, with the potential to scale up to 30Gbps in the future. While this is a lot faster than anything currently on the market, the significant advance here is the reception and transmission of terahertz waves (300GHz to 3THz) using a chip and antenna that's just two centimeters long. Rohm says it will only cost $5 when it comes to market in a few years — a stark comparison to current terahertz gear that's both large and expensive. The problem with terahertz transmissions, though, is that it's highly directional — with a submillimeter wavelength, it's more like a laser than a signal. Terahertz waves might enable awesome device-to-device networks, but it isn't going to bring 30Gbps internet to a whole city block. More interestingly, submillimeter terahertz radiation is the next step up from the gigahertz radiation used in full-body millimeter wave scanners. Terahertz waves can not only see through clothing, but can also penetrate a few millimeters of skin."

MrSeb writes with this ExtremeTech excerpt aimed at the graphene enthusiasts out there: "You can add another crazy characteristic to graphene's ever-expanding list of 'wonder material' properties: It can now be used to create flexible, transparent thin-film transistors. ... using an inkjet printer. The discovery comes from researchers at the University of Cambridge, UK, who were trying to ameliorate the lackluster performance of existing inkjet-printed electronics. It's already possible to print standard CMOS transistors using different ferroelectric polymer inks, but the resultant circuit is so slow that it can't actually function as a computer. If graphene could replace or augment the interconnects or transistors, these circuits would be a lot faster — and that's what these Cambridge engineers have done. Furthermore, if you didn't think that was cool enough, the graphene-based ink that they've developed is transparent, too."

judgecorp writes "Researchers at Stanford University have invented a battery material that could allow batteries to go through 400,000 charging cycles instead of the 400 or so which today's Li-ion batteries can manage. Among the uses could be storing energy to even out the availability of renewable sources such as sun and wind." Adds a story at ExtremeTech, "The only problem is, a high-voltage cathode (-) requires a very low-voltage anode (+) — and the Stanford researchers haven’t found the right one yet; and so they haven’t actually made a battery with this new discovery."

MrSeb writes with this excerpt from an article in Extreme Tech: "Light-emitting diodes are a cornerstone of consumer tech. They make thin-and-light TVs and smartphones possible, provide efficient household, handheld, and automobile illumination, and, of course, without LEDs your router would not have blinkenlights. Thanks to some engineers from MIT, though, a new diode looks set to steal the humble LED's thunder. Dubbed a diode for light, and crafted using standard silicon chip fabrication techniques, this is a key discovery that will pave the path to photonic (as opposed to electronic) pathways on computer chips and circuit boards. The diode for light — which is made from a thin layer of garnet — is transparent in one direction, but opaque in the other. Garnet is usually hard to deposit on a silicon wafer, but the MIT researchers found a way to do it."

MrSeb writes "According to multiple independent sources, AMD has canned its 28nm Brazos-based Krishna and Wichita designs that were meant to replace Ontario and Zacate in the second half of 2012. The company will likely announce a new set of 28nm APUs at its Financial Analyst Day in February — and the new chips will be manufactured by TSMC, rather than its long-time partner GlobalFoundries. The implications and financial repercussions could be enormous. Moving 28nm APUs from GloFo to TSMC means scrapping the existing designs and laying out new parts using gate-last rather than gate-first manufacturing. AMD may try to mitigate the damage by doing a straightforward 28nm die shrink of existing Ontario/Zacate products, but that's unlikely to fend off increasing competition from Intel and ARM in the mobile space."

If you'd rather keep your data private, take heart: disk encryption is a lot harder to break than techno-thriller movies and TV shows make it out to be, to the chagrin of some branches of law enforcement. MrSeb writes with word of a paper titled "The growing impact of full disk encryption on digital forensics" [abstract here to paywalled article] that illustrates just how difficult it is. According to the paper, co-authored by a member of US-CERT, "[T]here are three main problems with full disk encryption (FDE): First, evidence-gathering goons can turn off the computer (for transportation) without realizing it's encrypted, and thus can't get back at the data (unless the arrestee gives up his password, which he doesn't have to do); second, if the analysis team doesn't know that the disk is encrypted, it can waste hours trying to read something that's ultimately unreadable; and finally, in the case of hardware-level disk encryption, tampering with the device can trigger self-destruction of the data. The paper does go on to suggest some ways to ameliorate these issues, but ultimately the researchers aren't hopeful: 'Research is needed to develop new techniques and technology for breaking or bypassing full disk encryption.'"

MrSeb writes "Did you know that Newegg is the second largest e-tailer in the U.S., after Amazon? Perhaps building your own computer isn't dead yet! Matthew Murray was recently invited to take a tour of the Newegg east coast distribution center and see what goes on behind the scenes. 'The 350,000-square-foot Edison warehouse not only houses some 15,000 SKUs of products, it also ships as many as 15,000 packages a day ... All of the different products the company carries are sorted both by category and how easy they are to move: Obviously, HDTVs are more cumbersome and difficult to remove safely than processors. Some mobile equipment, such as laptops, netbooks, and tablets, are stored in a special “high-value” area behind a chain-link fence that’s been erected within the warehouse itself.'"

MrSeb writes "'Last week, Intel announced that it had added x86 optimizations to Android 4.0, Ice Cream Sandwich, but the text of the announcement and included quotes were vague and a bit contradictory given the open nature of Android development. After discussing the topic with Intel we've compiled a laundry list of the company's work in Gingerbread and ICS thus far, and offered a few of our own thoughts on what to expect in 2012 as far as x86-powered smartphones and tablets are concerned.' The main points: Intel isn't just a chip maker (it has oodles of software experience); Android's Native Development Kit now includes support for x86 and MMX/SSE instruction sets and can be used to compile dual x86/ARM, 'fat' binaries; and development tools like Vtune and Intel Graphics Performance Analyzer are on their way to Android."

MrSeb writes with this excerpt from an Extreme Tech article: "With 400 transistors and standard CMOS manufacturing techniques, a group of MIT researchers have created the first computer chip that mimics the analog, ion-based communication in a synapse between two neurons. Scientists and engineers have tried to fashion brain-like neural networks before, but transistor-transistor logic is fundamentally digital — and the brain is completely analog. Neurons do not suddenly flip from '0' to '1' — they can occupy an almost-infinite scale of analog, in-between values. You can approximate the analog function of synapses by using fuzzy logic (and by ladling on more processors), but that approach only goes so far. MIT's chip is dedicated to modeling every biological caveat in a single synapse. 'We now have a way to capture each and every ionic process that's going on in a neuron,' says Chi-Sang Poon, an MIT researcher who worked on the project. The next step? Scaling up the number of synapses and building specific parts of the brain, such as our visual processing or motor control systems. The long-term goal would be to provide bionic components that augment or replace parts of the human physiology, perhaps in blind or crippled people — and, of course, artificial intelligence. With current state-of-the-art technology it takes hours or days to simulate a simple brain circuit. With MIT's brain chip, the simulation is faster than the biological system itself."

harrymcc writes "On November 15th 1971, Intel introduced the 4004 — the first single-chip microprocessor. Its offspring, needless to say, went on to change the world. But first, Intel tried using the 4004 in a bunch of products that were interesting but often unsuccessful — like a pinball machine, an electronic vote-counting machine, and Wang's first word processor. Technologizer's Benj Edwards is celebrating the anniversary with an illustrated look back at this landmark chip." Here's another nostalgic look back at V3.co.uk, and one at The Inquirer. And an anonymous reader points out another at ExtremeTech, from which comes this snippet: "Designed by the fantastically-forenamed Federico Faggin, Ted Hoff, and Stanley Mazor, the 4004 was a 4-bit, 16-pin microprocessor that operated at a mighty 740KHz — and at roughly eight clock cycles per instruction cycle (fetch, decode, execute), that means the chip was capable of executing up to 92,600 instructions per second. We can’t find the original list price, but one source indicates that it cost around $5 to manufacture, or $26 in today’s money."

MrSeb writes "Ahead of tomorrow's full-scale launch of Amazon's new wunderkind, panacea, and lynch-pin of its continuing distribution domination, initial reviews of the Kindle Fire are starting to trickle in... and they're not as fantastic as we had hoped. Unsurprisingly, not a single review is denying that the bright screen, solid construction, and $200 price point make for a perfect holiday season outing — but to actually win the hearts of consumers, to steal those throbbing, Cupertino-captivated organs away from the iPad, the Kindle Fire has to be amazing... and it isn't. Throughout almost every review, one particularly telling observation rears its ugly head: the Kindle Fire can be sluggish. Page turns can lag. Menus can be slow to load. Screen touches can be unresponsive. For a device that is entirely about media consumption, the Fire will live or die depending on its perceived alacrity. If an E Ink Kindle or Nook is better for reading books, and a smartphone or iPad is better for watching movies or listening to music, what space is there for the Fire?"

MrSeb writes "In the Linux world, a war has been raging for a couple years. At stake are the hearts and minds of its user base. The combatants: the various distributions of Linux itself. For some time, Ubuntu Linux has been the clear leader in the fight, amassing more users than any other. Canonical and its baby seemed poised to take over the Linux desktop/laptop market completely — until it released Unity. Unity has caused an uproar in the Linux community — especially amongst the power users who decry its lack of customizability and inability to scale on big- and multi-monitor setups — and users are defecting in droves to Linux Mint, now the second most popular Debian-based distro and gaining fast on Ubuntu. Mint has very similar commands and shortcuts to Ubuntu, runs most apps the same as Ubuntu, and you can customize it to look and feel exactly how you want — which, for most users of Linux, is exactly what they want."
