HDMI 2.1 is here with 10K and Dynamic HDR support

Back in January, the HDMI Forum unveiled its new specifications for the HDMI connector , called HDMI 2.1. Now, that HDMI specification is available to all HDMI 2.0 adopters. It’s backwards compatible with all previous HDMI specifications. The focus of HDMI 2.1 is on higher video bandwidth; it supports 48 GB per second with a new backwards-compatible ultra high speed HDMI cable. It also supports faster refresh rates for high video resolution — 60 Hz for 8K and 120 Hz for 4K. The standard also supports Dynamic HDR and resolutions up to 10K for commercial and specialty use. This new version of the HDMI specification also introduces an enhanced refresh rate that gamers will appreciate. VRR, or Variable Refresh Rate, reduces, or in some cases eliminates, lag for smoother gameplay, while Quick Frame Transport (QFT) reduces latency. Quick Media Switching, or QMS, reduces the amount of blank-screen wait time while switching media. HDMI 2.1 also includes Auto Low Latency Mode (ALLM), which automatically sets the ideal latency for the smoothest viewing experience. If you’re not sure what this HDMI upgrade means, this handy chart provided by the HDMI forum makes it clearer. You can clearly see how upgraded specifications have increased support for different features as specifications improved. Source: HDMI Forum

macOS High Sierra bug allows full admin access without a password

If you’re using Apple’s latest macOS High Sierra, you’ll want to be wary of giving people access to your computer. Initially tweeted by developer Lemi Orhan Ergin, there’s a super-easy exploit that can give anyone gain admin (or root) rights to your Mac. Engadget has confirmed that you can gain root access in the login screen, the System Preferences Users & Groups tab and File Vault with this method. All you need to do is enter “root” into the username field, leave the password blank, and hit Enter a few times. Needless to say, this is some scary stuff. Root access allows someone to access your machine as a “superuser” with read and write privileges to many ore system files, including those in other macOS accounts. Luckily, the fix is fairly easy. As developer Colourmeamused tweeted, you need to set a root password: Everyone with a Mac needs to set a root password NOW. As a user with admin access, type the following command from the Terminal. sudo passwd -u root Enter your password then a new password for the root user. Anyone got a better fix? @SwiftOnSecurity @rotophonic @pwnallthethings — colourmeamused (@colourmeamused_) November 28, 2017 Engadget has confirmed that this will secure your macOS High Sierra machine, and keep people from gaining root access as above. We’ve reached out to Apple and will update this post when we hear back. Via: The Register Source: Lemi Orhan Ergin (Twitter) , Colourmeamused (Twitter)

Infiniti unveils a semi-autonomous QX50 for 2019

After nearly a year of teasing, Infiniti finally debuted its newest QX50 crossover at the 2017 Los Angeles Auto Show on Tuesday. The vehicle features not only an inline-4 engine capable of adjusting the length of each cylinder’s piston stroke on the fly, it’s also the first Infiniti to incorporate Nissan’s ProPilot semi-autonomous driver assist system. THe QX50 will sport a 2.0-liter inline-4 VC-Turbo engine that generates 268 HP and 280 pound-feet of torque yet will still provide an estimated 27 miles to the gallon (26 MPG if you turn on the AWD). It manages this impressive feat thanks to variable compression design. Specifically, the Q50 will adjust the cylinder compression ratio from 8:1 to 14:1 on demand, enabling it quickly switch between a fuel efficient low-boost, high-compression operation to a more powerful high-boost, low-compression setup — all within the span of 1.5 seconds. Additionally, the QX50 will be the first Infiniti to offer Nissan’s ProPilot semi-autonomous driver assist system, which can already be found in the 2018 Nissan Rogue and Leaf models. Think of the ProPilot system as an enhanced cruise control. It takes partial command of the vehicle’s acceleration, braking and steering operations to maintain your bearing and speed while travelling along the open road. Should traffic slow, the system will automatically reduce the QX50’s speed to keep you from crowding cars in front of you. When the flow of traffic speeds back up, the system will accelerate accordingly. The QX50 is expected to hit dealer show floors in the first quarter of next year.

Microsoft’s latest Windows 10 experiment: Running apps in tabs

When it comes to multitasking, few UI upgrades were as helpful as browser tabs. Instead of juggling dozens of windows on your computer, they let you place multiple websites in a single pane. It’s the sort of thing we take for granted today — especially if you don’t remember the pre-tab dark ages. With its latest feature in Windows 10, currently dubbed “Sets, ” Microsoft has taken some major cues from what browser makers learned years ago. Basically, it lets you group together Windows apps in tabs. That might sound simplistic, but Sets (which isn’t the final name yet) could fundamentally change the way we work in Microsoft’s OS. If you’ve seen the way the Edge browser handles tabs, you’ve already got a handle on Sets. You open a new tab within a window by clicking the plus button in the title bar. Once you’ve done that, you’ll see a landing page listing your most frequently used apps, recent documents and a search bar for local files and the web. As you’d expect, whatever you end up opening appears right alongside the original app you were using. So, if you started with a Word document, you could easily have a Powerpoint file, web pages and your Mail app sitting alongside it. It feels similar to how Chromebooks handle multitasking, an OS that has an interface almost entirely made up of browser tabs. Conceptually, Sets goes hand-in-hand with the upcoming Windows Timeline , which lets you jump backwards to continue working on past projects. While the two features were conceived separately, according to Microsoft, they could make for a powerful combination. It’s easier for the OS to tell that a collection of tabs within a single window are related to one project, which in turn makes it simpler for Timeline to get you back up and running. Additionally, Windows will also be able to open up the Set you typically use with a particular document. While Sets might seem like an obvious UI evolution for Windows, it’s still a significant move for Microsoft. For one, it marks the biggest change we’ve seen to the title bar since Windows 95. Even the drastic UI overhaul in Windows 8 didn’t affect that much. Perhaps that’s why Microsoft is clearly positioning it as an experiment. Initially, only a handful of Windows Insider participants will get access to it. The company will also perform a controlled study on how people use the feature. While Microsoft says everyone in the Insider Program will eventually have access, it’ll likely be a while before that happens. Initially, Sets will work with Universal Windows apps like Mail, Calendar and Edge. After that, the company will work on bringing simpler apps like Notepad onboard, and it’s also developing a Sets-compatible version of office. Supporting more complex apps, like Photoshop and Premiere, will take even longer. And if none of this sounds compelling, you’ll also be able to turn off Sets (or whatever it ends up being called) in your Control Panel. Microsoft also plans to offer granular control for the feature, allowing you to turn it off for specific apps. What’s most interesting about Sets is how Microsoft is carefully rolling it out. Unlike Windows 8, which dramatically killed off the Start Menu and replaced it with something slower and clunkier, the company is taking care not to disrupt how we normally work in its OS. It’s a humbling admission by Microsoft that it might not always know what’s best for its users. But this time, at least, it’s prepared to learn.

Tom Baker Returns To Finish Shelved Doctor Who Episodes Penned By Douglas Adams

Zorro shares a report from The Register: The fourth and finest Doctor, Tom Baker, has reprised the role to finish a Who serial scuppered in 1979 by strike action at the BBC. Shada, penned by Hitchhiker’s Guide author Douglas Adams, was supposed to close Doctor Who’s 17th season. Location filming in Cambridge and a studio session were completed but the strike nixed further work and the project was later shelved entirely for fear it might affect the Beeb’s Christmas-time productions. The remaining parts have been filled in with animation and the voice of 83-year-old Baker, although he also filmed a scene. BBC Worldwide has now released the episodes, which interweave the 1979 footage with the new material to complete the story. “I loved doing Doctor Who, it was life to me, ” Baker told the BBC of his tenure as the much-loved Time Lord. “I used to dread the end of rehearsal because then real life would impinge on me. Doctor Who… when I was in full flight, then I was happy.” Read more of this story at Slashdot.

Origami-like soft robot can lift 1000 times its weight

Soft robotics allow machines to move in ways which mimic living organisms, but increased flexibility usually means reduced strength , which limits its use. Now, scientists at MIT CSAIL & Harvard have developed origami-like artificial muscles that add much-needed strength to soft robots, allowing them to lift objects as much as 1, 000 times their own weight using only water or air pressure. One 2.6 gram muscle is able to lift a 3 kilogram object, which is the same as a duck lifting a car. The artificial muscles are made up of a plastic inner skeleton surrounded by air or water inside a sealed bag — the “skin”. Applying a vacuum to the inside of the bag initiates the muscle’s movement, creating tension that drives the motion. No power source or human input is needed to direct the muscle, as it’s guided purely by the composition of the skeleton . In experiments, the researchers created muscles that can lift a flower off the ground, twist into a coil and contract down to 10 percent of their original size. They even made a muscle out of a water-soluble polymer, which means the technology could be used in natural setting with minimal environmental impact . Other potential applications include deep sea research, minimally invasive surgery and transformable architecture. The muscles are scalable — the team built them at sizes ranging from a few millimeters up to a meter — and cheap to produce. A single muscle can be made in under ten minutes for less than a dollar. Even the research team itself was surprised by how effective the technology is. “We were very surprised by how strong the muscles were. We expected they’d have a higher maximum functional weight than ordinary soft robots, but we didn’t expect a thousand-fold increase, ” said CSAIL director Daniela Rus. “It’s like giving these robots superpowers .”

Microsoft built an AI-powered iOS app to help you learn Chinese

Language-learning apps are nothing new, with offerings from MIT and Duolingo ready to teach you a new way to communicate right on your phone. Now Microsoft is looking to teach you Chinese with a free new AI-powered iOS app. The idea here is to provide users with a way to practice the Chinese language in the absence of real-life communicative partners. “You think you know Chinese, but if you meet a Chinese person and you want to speak Chinese, there is no way you can do it if you have not practiced, ” said Microsoft’s Yan Xia in a blog post . “Our application addresses this issue by leveraging our speech and natural language processing technology.” There’s no word on plans to expand to other languages, but it’s not hard to see such an app helping you learn to converse in different tongues, too. The app uses various AI tools like deep neural networks that are able to figure out what you’re trying to say and then evaluate your pronunciation. The AI has been trained on data from native Chinese speakers as well as Microsoft’s text-to-speech technology. As you use the app, you’ll get scored on your speaking ability and highlighted words that you need to work on, plus sample audio to hear how the words are actually pronounced. So far, the app has separate systems for beginners and intermediate learners to better help you move forward from your level of expertise. “The app will work with you as a language learning partner, ” Xia said in the post. “It will chat with you and give you feedback based on what you are saying.” Source: Microsoft

iOS jailbreak repositories close as user interest wanes

 A few years ago jailbreaking your iPhone was all the rage. The cat-and-mouse game of hackers versus Apple was great fun and some of the open source products available to jailbreakers – namely the Cydia alternative app store – added amazing features and customizability to the iPhone. Some devs even launched only on jailbroken phones, thumbing their noses at Apple’s walled… Read More

Ubuntu 17.10: Return of the GNOME

Canonical’s video introduction to Ubuntu 17.10 If you’ve been following the Linux world at all, you know this has been an entire year for spring cleaning. Early in 2017, Canonical stopped work on its homegrown Unity desktop, Mir display server, and its larger vision of “convergence”—a unified interface for Ubuntu for phones, tablets, and desktops. And now almost exactly six years after Ubuntu first switched from GNOME 2 to the Unity desktop, that has been dropped, too . The distro is back to GNOME, and Canonical recently released Ubuntu 17.10, a major update with some significant changes coming to the popular Ubuntu Linux operating system. In light of the GNOME switch, this release seems like more of a homecoming than an entirely new voyage. But that said, Ubuntu 17.10 simultaneously feels very much like the start of a new voyage for Ubuntu. The last few Ubuntu desktop releases have been about as exciting as OpenSSH releases—you know you need to update, but beyond that, no one really cares. Sure, there’s been a few feature updates with each new numeric increment, perhaps some slightly more up-to-date GNOME and GTK components under the hood. But by and large, the Ubuntu’s Unity 7 desktop has been in maintenance mode for several years. Read 34 remaining paragraphs | Comments

IceCube detector uses entire Earth to measure interactions of neutrinos

Enlarge / The IceCube facility sits at the South Pole above an array of photodetectors, drawn into the image above. (credit: IceCube Collaboration, U. Wisconsin, NSF ) Neutrinos are one of the most plentiful particles out there, as trillions pass through you every second. But they’re incredibly hard to work with. They’re uncharged, so we can’t control their path or accelerate them. They’re also nearly massless and barely interact with other matter, so they’re hard to detect. All of this means that a lot of the predictions our physics theories make about neutrinos are hard to test. The IceCube detector , located at the South Pole, has now confirmed a part of the Standard Model of physics, which describes the properties of fundamental particles and their interactions. According to the Standard Model, neutrinos should become more likely to interact with other particles as their energy goes up. To test this, the IceCube team used neutrinos thousands of times more energetic than our best particle accelerators can make and used the entire planet as a target. Polar cube IceCube consists of hundreds of detectors buried in the ice under the South Pole. These detectors pick up particles that move through the ice. In some cases, IceCube sees a spray of particles and photons when something slams into one of the atoms in the ice. In other cases, particles simply nudge the atoms, liberating a few photons. There’s no neutrino source pointed at IceCube, though. Instead, it relies on natural sources of neutrinos. Some of these are produced far away in space, and travel great distances to Earth. Others are produced as cosmic rays slam into the atmosphere. Read 9 remaining paragraphs | Comments
