Review: Much-improved Iris GPU makes the Skylake NUC a major upgrade

Andrew Cunningham The new Skylake NUC. 10 more images in gallery Intel’s “Next Unit of Computing” (NUC) mini desktops started off as interesting curiosities, experiments to see just how much computer could fit in a desktop PC that you could hold in your hand. Each subsequent generation has refined the overall concept and added other niceties, making it more and more like a solid consumer-ready computer (albeit one that makes you provide your own RAM and SSD and OS). We looked at Intel’s fourth-generation NUC based on its still-relatively-new Skylake processors. On the outside, less has changed than ever before—Intel has settled on a “look” for the NUC and it’s not messing with the design much. On the inside, you get enough cool upgrades that you can almost forgive Intel’s CPU performance for improving so little in the last three or four years. Model breakdown Specs at a glance: Intel NUC NUC6i7SYK (as reviewed) OS Windows 10 x64 CPU 1.8GHz Core i5-6260U (Turbo Boost up to 1.9GHz) RAM 16GB 2133MHz DDR4 (supports up to 32GB) GPU Intel Iris 540 (integrated with 64MB eDRAM) HDD 256GB Samsung SM951 PCIe SSD Networking 867Mbps 802.11ac Wi-Fi, Bluetooth 4.2, Gigabit Ethernet Ports 4x USB 3.0, 1x mini DisplayPort 1.2, 1x HDMI 1.4b, headphones, SD card slot Size 4.53” x 4.37” x 1.26” (115 x 111 x 32mm) Other perks Kensington lock, swappable lids, IR receiver Warranty 3 years Price ~$400 (barebones), about $755 as configured There are four Skylake NUCs as of this writing. Two include a Core i5-6260U with an Iris 540 integrated GPU, and two use a slower Core i3-6100U processor and a slower HD 520 GPU. Each processor comes in two cases: a taller one that makes room for a 2.5-inch hard drive or SSD, and a shorter one that doesn’t. Otherwise, all models share the same basic design, port layout, and other features. Read 27 remaining paragraphs | Comments

Encrypted WhatsApp messages frustrate new court-ordered wiretap

(credit: Hernán Piñera ) The US Department of Justice has opened another legal front in the ongoing war over easy-to-use strong encryption. According to a Saturday report in The New York Times , prosecutors have gone head-to-head with WhatsApp, the messaging app owned by Facebook. Citing anonymous sources, the Times reported that “as recently as this past week,” federal officials have been “discussing how to proceed in a continuing criminal investigation in which a federal judge had approved a wiretap, but investigators were stymied by WhatsApp’s encryption.” The case, which apparently does not involve terrorism, remains under seal.

16 years later, Blizzard is still patching Diablo II

No rest for the weary. These days, you’re lucky if some titles from certain big publishers get a year or two of post-launch online support for their games before they’re unceremoniously dropped . And then there’s Diablo II . Blizzard issued a new version 1.14 patch for the nearly 16-year-old game Thursday, five years after the game was last officially updated (not to mention, four years since the game’s sequel launched with its own attendant post-release problems and patches ) The new Diablo II patch doesn’t add any new gameplay features, balance tweaks, or anything like that. Instead, Blizzard has added compatibility with modern operating systems like Windows 10 and OS X. But Blizzard says it’s working on improvements to the game’s “cheat-detection and hack-prevention capabilities” and hints at more improvements to come. “There is still a large Diablo II community around the world, and we thank you for continuing to play and slay with us,” Blizzard writes . “This journey starts by making Diablo II run on modern platforms, but it does not end there. See you in Sanctuary, adventurers.” Read 2 remaining paragraphs | Comments

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

No longer virtual: First impressions—and many hours—with HTC’s Vive Pre

The HTC Vive Pre comes with everything seen here. Some assembly required. Your parents help you put it together. From HTC! (credit: Kyle Orland) For about a year now , we’ve been absolutely wowed by short, controlled demos of the virtual reality tech in the SteamVR-powered HTC Vive. But enjoying a slick demo in a curated show floor booth is one thing. Having a Vive in your house to play with at your leisure is another. Ahead of its upcoming consumer launch, Valve has sent us loaner units of its near-final HTC Vive Pre to test in the Ars Orbiting HQ . I’ve spent a large portion of the past few days immersed in Valve’s room-scale vision of virtual reality, whiling away hours blind to the real world around me and trying not to kill myself walking around my office (which has never been cleaner, to make sure there are no tripping hazards about). We’ll have fuller reviews of the hardware and the most interesting VR experiences as we get closer to the Vive’s early April 9 release. For now, here are some scattered impressions of what it’s like having room-scale virtual reality in your very own room. Read 17 remaining paragraphs | Comments

Whole lotta onions: Number of Tor hidden sites spikes—along with paranoia

Two sudden leaps in the number of advertised “hidden services” on Tor have led to rampant speculation about the cause of them. (credit: The Tor Project ) In recent weeks, the number of “hidden services”—usually Web servers and other Internet services accessible by a “.onion” address on the Tor anonymizing network—has risen dramatically. After experiencing an earlier spike in February, the number of hidden services tracked by Tor spiked to 114,000 onion addresses on March 1. They then dropped just as quickly, falling to just below 70,000 hidden services seen by Tor on Thursday—still twice the number that Tor had held steady at for most of 2015. “We don’t know what’s causing this,” said Kate Krauss, the director of communications and public policy for the Tor Project. “But it’s not difficult for even one person—a researcher, for instance—to create a lot of new onion addresses—which is not the same as actual websites or services. In fact, we want the process of creating onion addresses to be as easy as possible to encourage the creation of more onion services. These spikes are typically temporary—and as you see from the chart, this one is already going away.” Still, there has never been this sort of wild gyration in their number in recent times—or at least as far back as the Tor Project has kept metric data. So what caused the sudden near-tripling of the size of Tor’s hidden Web and its rapid contraction? Based on a deeper look at Tor’s metrics and discussions with both Tor developers and security experts, the huge spike in the “size” of the hidden Web within Tor was likely caused by a perfect storm of coincidences: major Internet censorship events in at least two countries, the relatively rapid adoption of a new messaging tool, a malware explosion, and ongoing attempts to undermine the privacy of the network.

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.

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.

Microsoft kills off Qik, the video messaging service you didn’t know it had

Playing back a conversation, on the Windows Phone version. You’ll be forgiven for having forgotten about Skype Qik, the short video messaging service from Skype that Microsoft launched in October 2014. It offered low friction messaging—no need to create an account, merely having a phone number would do—similar to WhatsApp, SMS, or all sorts of other popular messaging services. Well, now it’s going away. The company says that the major features of Qik have been rolled into the regular Skype apps; video messaging already existed in Skype when Qik was released, and filters were added in October last year. As such, the app isn’t really needed any more, and Qik will stop working on March 24. Skype Qik was a successor to a short video messaging service called Qik that Skype bought in January 2011 for $150 million, just months before Microsoft bought Skype for $8.5 billion. The original Qik service was built around capturing video messages and sharing them with others. It was closed down in April 2014, as Skype introduced its own integrated video messaging capability. In that context, the new Skype Qik was a little strange, as it overlapped strongly with both the previously shuttered service, and the newly-added Skype capabilities.

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.
