TP-Link blocks open source router firmware to comply with new FCC rule

A TP-Link router. (credit: TP-Link. ) Networking hardware vendor TP-Link says it will prevent the loading of open source firmware on routers it sells in the United States in order to comply with new Federal Communications Commission requirements. The FCC wants  to limit interference with other devices by preventing user modifications that cause radios to operate outside their licensed RF (radio frequency) parameters. The FCC says it doesn’t intend to ban the use of third-party firmware such as DD-WRT and OpenWRT; in theory, router makers can still allow loading of open source firmware as long as they also deploy controls that prevent devices from operating outside their allowed frequencies, types of modulation, power levels, and so on. But open source users feared that hardware makers would lock third-party firmware out entirely, since that would be the easiest way to comply with the FCC requirements. The decision by TP-Link—described by the company in this FAQ —shows that those fears were justified.

Man hacks Tesla firmware, finds new model, has car remotely downgraded

The image that hacker Jason Hughes found hidden in Tesla’s latest Model S firmware. (credit: Jason Hughes) It seems Tesla is set to bump the battery capacity of its Model S sedan up to a hefty 100kWh some time in the near future. We know this thanks to the work of a white-hat hacker and Tesla P85D owner named Jason Hughes. Hughes—who previously turned the battery pack from a wrecked Tesla into a storage array for his solar panels—was poking around in the latest firmware of his Model S (version 2.13.77) and discovered an image of the new car’s badge, the P100D. Hughes let the world know via a cryptic tweet: @elonmusk @teslamotors #tesla I know your secret. SHA256 of best part: 5fc38436ec295b0049f186651ebba5fd55e8d7b81eb61cbd00d3f1bf18dd9c81 — Jason Hughes (@wk057) March 4, 2016 That message was soon decrypted by enthusiasts on the Tesla Motors Club forum, at which time Hughes posted a copy of the picture: Read 3 remaining paragraphs | Comments

Stretchable, glowing capacitors used to make a touch-sensitive robot

(credit: Larson, et. al., Science) For many of us, the term “robot” still evokes an image of R2D2 or a terminator-style collection of metal parts. But there’s no reason to limit our construction materials to hard parts. A number of labs are working on soft-bodied robots, and have shown they can do some rather interesting things, like squeezing through narrow spaces . A team of researchers from Cornell and the Istituto Italiano di Tecnologia have taken a soft-bodied robot and made it glow. Their method of producing the light, however, has some interesting side effects: it allows the robot to determine how much it has flexed, and it makes the robot responsive to touch. These days, “glow” is usually synonymous with “LED.” But the authors used a very different technique, relying on what’s called an electroluminescent phosphor—basically, something that glows when it’s place in an alternating electric field. The phosphors (zinc sulfide, in this case) can be embedded in a silicone gel, making them stretchable and bendable. Different dopants in the phosphor will cause it to glow in different colors.

Largely undetected Mac malware suggests disgraced HackingTeam has returned

Enlarge (credit: Patrick Wardle ) Researchers have uncovered what appears to be newly developed Mac malware from HackingTeam, a discovery that’s prompting speculation that the disgraced malware-as-a-service provider has reemerged since last July’s hack that spilled gigabytes worth of the group’s private e-mail and source code . The sample was uploaded on February 4 to the Google-owned VirusTotal scanning service , which at the time showed it wasn’t detected by any of the major antivirus programs. (Ahead of this report on Monday, it was detected by 10 of 56 AV services.) A technical analysis published Monday morning by SentinelOne security researcher Pedro Vilaça showed that the installer was last updated in October or November, and an embedded encryption key is dated October 16, three months after the HackingTeam compromise. The sample installs a copy of HackingTeam’s signature Remote Code Systems compromise platform, leading Vilaça to conclude that the outfit’s comeback mostly relies on old, largely unexceptional source code, despite the group vowing in July that it would return with new code.

OS X blacklist accidentally disables Ethernet in OS X 10.11

Enlarge / An errant update may have disabled your Mac’s Ethernet port recently. (credit: Andrew Cunningham) If you’re having problems with your Mac’s Ethernet port this morning, the culprit may be an errant automatic update that Apple published over the weekend. Luckily, the damage isn’t permanent: an Apple support article posted yesterday will walk you through diagnosing and fixing the problem, which involves connecting to your network via Wi-Fi and running a software update command in the Terminal. If you’re reading this and your Ethernet port is working fine, odds are good that you’ve already installed the follow-up update released to fix the problem. The culprit is an update for the System Integrity Protection feature for OS X, the El Capitan feature that protects some system folders and keeps unsigned or incorrectly signed kernel extensions (or “kexts,” roughly analogous to drivers in a Windows or Linux machine) from loading. In this case, the kext used to enable the Ethernet port on Macs was blacklisted—if you restarted your Mac after applying this update but before your computer had a chance to download the quickly issued fix, you’ll find yourself without an Ethernet connection. This blacklist isn’t updated through the Mac App Store like purchased apps or OS X itself. Rather, it uses a seamless auto-update mechanism that executes in the background even if you haven’t enabled normal automatic updates. Apple uses a similar mechanism to update OS X’s anti-malware blacklist, a rudimentary security feature introduced in 2011 following the high-profile Mac Defender malware infection and occasionally used to push other critical software updates .

Pentium? Core i5? Core i7? Making sense of Intel’s convoluted CPU lineup

Intel’s Skylake-based Pentium G4500. (credit: Andrew Cunningham) Our creative director Aurich Lawson is building a PC to power a custom arcade cabinet, and he was having trouble picking a processor. Not because he didn’t know what he needed, but because he was having trouble matching what he needed (the cheapest quad-core CPU that meets the recommended requirements for Street Fighter V ) with what Intel was offering (five different obfuscated brands spread out over multiple sockets and architectures). And if you’re building a PC now after having been out of the game for a few years, it can be exceptionally confusing. Around the turn of the millennium you just had Celeron and Pentium. One name meant “cut-down low-end” and one meant “high-end, more features,” and you just bought the fastest one you could reasonably afford. Things got a little more confusing in the Core and Core 2 days (the Core branding continues to survive alongside the Celeron and Pentium brands), but you could at least use names like “Core Solo” and “Core 2 Quad” to guess which architecture and how many cores you were getting. Now there are three separate Core brands, Pentium and Celeron brands, and a long series of letters that you need to know to figure out what CPU you’re getting. It’s been a few years since the last time we demystified Intel’s CPU lineup, and in truth things haven’t changed too much. In broad strokes, the rules are the same. But Intel has introduced and retired a few CPU architectures and brands since then. We’ll run down the basics for both desktops and laptops to help you make some sense of things whether you’re building a computer or buying one from someone else.

Next-gen Ultra HD Blu-ray discs probably won’t be cracked for a while

DVDFab, a software tool for ripping and decrypting DVDs and Blu-ray discs, will not be upgraded to support newer Ultra HD (4K) Blu-ray discs. Fengtao Software, which makes DVDFab, said in a statement that it “will not decrypt or circumvent AACS 2.0 in the days to come. This is in accordance with AACS-LA, (which has not made public the specifications for AACS 2.0), the BDA [Blu-ray Disc Association] and the movie studios.” AACS-LA is the body that develops and licenses the Blu-ray DRM system. Curiously, Fengtao’s announcement comes just a day after SlySoft—the company that makes the ripping tool AnyDVD—ceased operations and vanished from the Web . All that’s left is a cryptic message on SlySoft’s website: “Due to recent regulatory requirements we have had to cease all activities relating to SlySoft Inc.” Read 5 remaining paragraphs | Comments

Report: Siri for Mac will be one of OS X 10.12’s major new features

(credit: Apple) Apple’s Siri personal assistant will finally be coming to OS X 10.12 when the OS is released later this year, according to a report from 9to5Mac . According to the report, a Siri icon will live in the menu bar in the upper-right corner of the screen along with icons for Spotlight, the Notification Center, and other features. Users will also be able to use a keyboard shortcut to bring up Siri, which will be an optional feature that can be enabled during first-time setup or in System Preferences (much as it works in iOS today). Microsoft’s Cortana feature made a similar jump from Windows Phone 8.1 to Windows 10 last year, and Google supports its “OK Google” voice commands in Chrome OS as well. Since launching on the iPhone 4S in 2011, Siri has become a mainstay in most of Apple’s products; it spread to the iPad relatively quickly, it came to the Apple TV when it was refreshed last year, and it’s a primary input method for the Apple Watch. OS X already supports an optional Dictation feature for turning speech into text—in other words, the feature is a natural and long-awaited addition to the Mac platform.

Valve releases tool to test whether your PC is VR ready

(credit: Valve ) With HTC beginning to take pre-orders for the SteamVR-powered Vive headset in just one week, you may well be wondering if your PC tower is up for running high-end VR without any distracting lag. Worry not: Valve has just released a SteamVR Performance Test Tool to determine whether you are technologically ready to shell out $799 for an HTC Vive . Unlike Oculus’ own Rift Compatibility Tool , which just seems to check your PC parts against a list without actually running a diagnostic, Valve’s tool takes a few minutes to run through a small, non-interactive animation of a GLaDOS robot repair facility. The goal is to “determine whether your system is capable of running VR content at 90fps and whether VR content can tune the visual fidelity up to the recommended level,” according to a Valve blog post . Afterwards, the tool gives an average fidelity rating (on a numerical and Low/Medium/High/Very High scale). It also tells you what percentage of tested frames dipped below the recommended 90 fps for a smooth VR experience and whether any of those frames were bound by the CPU, rather than the GPU. The tool does warn that “the varying CPU cost of positional tracking and processing-intensive applications” could mean actual software runs worse than the test would suggest and warns that it doesn’t test for available USB slots either.

Tiny micro-supercapacitors built directly on a chip

(credit: Drexel University ) Since the tech boom began decades ago, we’ve seen a dramatic transformation of electronics. Today, some technological dreamers are talking about “smart environments” where electronics are seamlessly integrated into our environment, providing comfort and convenience. For these dreams to be achieved, we need to get electronics—not just the chips—miniaturized to the point where sensors can be pervasive. This involves developing high-performance electrochemical storage devices to enable long-lived sensors and radio frequency identification (RFID) tags. But efficient miniaturized energy storage devices have proven to be challenging to create; it can be done, but it’s hard to integrate the results with other electronics. Supercapacitors According to an article in Science , an international team of scientists has now reported some progress in this area—specifically with the design of micro-supercapacitors. Supercapacitors are a class of materials that can store energy through accumulation of charge at the surface of a high-surface-area carbon sheet. They typically have a good cycle life, moderate energy density (6 Wh/kg), and high power densities (> 10 kW/kg). Supercapacitors are a great replacement for batteries in applications that require high power delivery and uptake with a very long charge-discharge cycle life; micro-supercapacitors are the same kind of material but much, much smaller.
