VESA publishes Embedded DisplayPort 1.4a standard that supports 8K displays

VESA, the standards body responsible for such luminary technologies as DisplayPort and the omnipresent VESA monitor mount, has published the specification for version 1.4a of Embedded DisplayPort (eDP). The new standard builds upon DisplayPort 1.3, which was published at the end of 2014. In short, eDP 1.4a allows for laptops, smartphones, tablets, and all-in-ones with 8K displays (7680×4320) or high-frequency (120Hz) 4K displays—but it includes a few other neat features, too. eDP 1.4a appears to be almost entirely based on DisplayPort 1.3—which was published in September 2014—with a couple of new features thrown in for good measure. eDP 1.4a specifies four high-speed (HBR3) lanes between the graphics adapter and display, with each lane capable of 8.1Gbps; the lanes can either be used individually, in pairs (more on that later), or all together for a total theoretical bandwidth of 32.4Gbps. That’s enough bandwidth to drive a 4K display (3840×2160) at 120Hz with 10-bit color or an 8K display at 60Hz. Beyond higher bandwidth, one of the more interesting features of eDP 1.4a is Direct Stream Compression (DSC), a standard developed by VESA and MIPI that—as the name implies—compresses the output video signal. According to VESA, the compression is “visually lossless” (i.e., it is lossy, but your games won’t suddenly look like a hand-me-down JPEG). VESA and MIPI say that DSC can reduce the component cost and power consumption of high-resolution displays—a claim that obviously needs to be confirmed once eDP 1.4a devices start shipping.

Palm-sized pwnage: Ars tests the Pwn Plug R3

Imagine for a moment the following scenario: you’re the manager for a busy bank branch in a major city. You come back from lunch and are told by one of your employees that someone from corporate IT dropped by to check on a reported problem with a branch PC. You don’t remember putting in a trouble ticket with IT, but apparently the guy left after looking under a desk and re-plugging a network cable or something. It took less than five minutes. You think nothing of it and go back to approving loans. Three days later, you get a call from the head of corporate security, wanting to know why someone at your branch has been performing wire transfers from the accounts of customers who’ve never used your branch to accounts at offshore banks. A few hours later, you’re unplugging the bank’s network equipment while he’s shouting at you over the phone about gigabytes of corporate data being pulled down from something in your bank. And when the security team and police arrive to investigate, they find a little nondescript box plugged into a network port, connected to a broadband cellular modem. Something like this happened to banks in London last year . A man posing as an IT contractor wired networked keyboard-video-monitor (KVM) switches connected to cellular routers into PCs at two bank branches. The ring involved with the thefts was only caught because they decided to go for a third score, and their “technician” was caught in the act. The digital heists were a variation on the hacker “drop box” strategy: boldly walking into a place of business and planting a device, often hidden in plain sight, to use as a Trojan horse to gain remote access to the business’ network.

Yoga Pro 3 review: Broadwell is a mixed blessing

It arrived on a wave of new Windows 8-oriented devices that tried all manner of new things to offer the best of the traditional laptop and the tablet experience. The Yoga’s premise was simple: make a hinge that bends all the way around, so you can fold the laptop back on itself to make it into a sort of chunky laptop. It skewed more heavily towards laptop usage than tablet usage—there are no compromises when using it as a laptop, unlike, for example, Microsoft’s Surface Pro range—but still offered that flexibility for those who wanted it. Although designed to let the device transform into a tablet, it is perhaps the other positions that have been the real winners with the Yoga’s hinge: what Lenovo calls “tent mode,” where the keyboard is folded most of the way back to prop the screen up, is excellent when watching movies in planes and similar cramped situations, as it drastically shrinks the footprint of the device. This flexibility made the Yoga design one of the big winners. Read 22 remaining paragraphs | Comments

A power user’s guide to OS X Server, Yosemite edition

Welcome to Yosemite Server. Andrew Cunningham OS X Server is in maintenance mode. That much was clear when Mavericks Server came out a year ago with just a handful of welcome-but-minor tweaks and improvements. The software hasn’t grown stagnant, really—certainly not to the extent of something like Apple Remote Desktop, which only gets updated when it’s time to support a new OS X version. But now OS X Server is changing very little from version to version, and since the untimely death of the Mac Mini Server , Apple isn’t even selling any kind of server-oriented hardware. Still, the Yosemite version of OS X Server changes enough to be worth revisiting. As with our pieces on Mavericks and Mountain Lion , this article should be thought of as less of a review and more of a guided tour through everything you can do with OS X Server. We’ll pay the most attention to the new stuff, but we’ll also detail each and every one of OS X Server’s services, explaining what it does, how to use it, and where to find more information about it. In cases where nothing has changed, we have re-used portions of last year’s review with updated screenshots and links.

Geothermal energy has success in Nevada, wants to spread to the rest of the west

Megan Geuss RENO, NV—On an uncharacteristically rainy day in Western Nevada, a small tour bus of journalists rumbled past security gates at the Ormat Steamboat Complex in Washoe County. We were there to learn about geothermal power, a renewable energy resource produced by transferring heat from underground rocks up to power plants. Most people think of Iceland when they think of geothermal power. On that island, approximately 90 percent of homes are heated by geothermal energy. But some 12 gigawatts of geothermal power are generated worldwide, and the US is one of the largest producers of it, generating nearly 3.4 gigawatts in 2013 . Ormat’s Steamboat Complex is within the Reno city limits, and it’s made up of seven smaller plants that collectively generate 78 megawatts of power. A typical coal-fired power plant can generate around 660 megawatts of power , so Ormat’s 78 megawatts are not a lot by comparison. But when compared to other renewables, geothermal has some advantages. Read 23 remaining paragraphs | Comments

After 10 years, Rosetta probe catches up with its comet destination

Today, the European Space Agency announced that its Rosetta mission successfully arrived at comet 67P/Churyumov-Gerasimenko after a 10-year journey. As the probe approached over the past several weeks, it provided greater detail on the oddly shaped comet, which was venting water as its orbit drew it closer to the Sun. Now, at just 100km from the comet’s surface, Rosetta is providing detailed images of a truly otherworldly landscape. 67P/Churyumov-Gerasimenko occupies an elliptical orbit that takes it from areas beyond Jupiter to somewhere in between Earth and Mars (currently, it’s midway between Jupiter and Mars). That presents a significant challenge, since any probe intended to track the comet must roughly match its orbit before approaching—or it would need a prohibitive volume of propellant to slow down. This explains Rosetta’s 10-year journey, which included four orbital flybys of Earth and Mars to put it in place for a gradual approach. Earlier this year, Rosetta successfully woke from hibernation , and it’s been imaging the comet during its approach. Early images indicated that 67P/Churyumov-Gerasimenko has a two-lobed structure that some have compared to a rubber duck, albeit one with an unusually large head. The second lobe, corresponding to the duck’s body, is broader and more oblong. Read 3 remaining paragraphs | Comments

NASA decides on crowdsourced Tron look for Mars Z-2 spacesuit

NASA The winning Z-2 suit design, “Technology,” standing triumphantly on a 3D-rendered martian rocky outcropping. 14 more images in gallery NASA announced today that it has finalized the look for its new Mars-bound Z-2 space suit. The design was selected by the public in a vote, and the winning design was one of three showcased by the agency . The new suit is the latest in NASA’s Z-series of suits. These are a far cry from the simple pressure suits worn by the Mercury astronauts in the 1950s—today’s suits aren’t so much suits as person-shaped spaceships. The Z-series suits are being designed to function both in space and also on the ground on other worlds, most notably the moon and Mars. The major design focuses of the Z-series, and the Z-2 in particular, are mobility and ease of use. Since the earliest days of space travel, suited astronauts needed to cope with the tremendous physical burden of working inside what is essentially a rigid pressurized balloon; an air-filled space suit resists bending, and multi-hour spacewalks can be exhausting. Future suits like the Z-series try to help out their occupants with new materials and clever joint designs, not to mention by allowing astronauts to vary their pressurization level.
