Linux Might Need To Claim Only ACPI 2.0 Support For BIOS 129

Posted by timothy
from the and-you-can-taqiya-that-to-the-bank dept.
jones_supa writes Some of us remember the story of why Linux kernel responds "False" when ACPI BIOS asks if the operating system is Linux. We have found yet another case where mimicking the Windows behavior instead of writing to the spec is the right choice if you just want your machine to work properly. The ACPI spec defines the _REV object as evaluating to the revision of the ACPI specification that the OS implements. Linux returns 5 for this, because Linux actually tries to implement ACPI 5.0, but Windows returns 2 (ACPI 2.0), possibly due to legacy reasons. Linux kernel expert Matthew Garrett discovered that still a fair amount of brokenness appears when 5 is returned as the revision, including a Dell machine which left the sound hardware in a misconfigured state. He is proposing a kernel patch which simply reports _REV as 2 on all x86 hardware.

Dell Venue 8 7000, "World's Thinnest Tablet" With Intel Moorefield Atom Reviewed 120

Posted by timothy
from the straight-outta-round-rock dept.
MojoKid (1002251) writes "Dell recently launched their Android-based Venue 8 7000 slate, claiming it's the "world's thinnest" tablet. It measures a mere 6 millimeters thick, or 0.24 inches and change. That's 0.1mm slimmer than Apple's iPad Air 2 and 1.5mm flatter than the iPad mini 3, giving Dell full bragging rights, even if by a hair. Dell also opted for an Intel Atom Z3580 processor under the hood, clocked at up to 2.3GHz. This quad-core part is built on Intel's 22nm Moorefield microarchitecture. Compared to its Bay Trail predecessor, Moorefield comes in a smaller package with superior thermal attributes, as well as better graphics performance, courtesy of its PowerVR G6430 graphics core. The Venue 8 7000 also features one of the best 8-inch OLED displays on the market, with edge-to-edge glass and a 2560x1600 resolution. Finally, the Venue 8 7000 is also the first to integrate Intel's RealSense Snapshot Depth Camera, which offers interesting re-focusing and stereoscopic effects, with potentially other, more interesting use cases down the road. Performance-wise, the Venue 8 7000 is solid enough though not a speedster, putting out metrics in the benchmarks that place it in the middle of the pack of premium tablets on the market currently."

Dell Continues Shipping Fresh Linux Laptops 123

jones_supa writes: In its latest move, Dell will be bringing Ubuntu 14.04 LTS to its top-of-the-line Precision M3800 workstation laptop and the latest model of the Dell XPS 13. Both systems will be running Ubuntu 14.04.1. According to Barton George, Dell's Director of Developer Programs, programmers had been asking for a better, officially-supported Ubuntu developer laptop. This came about from a combination of the efforts of Dell software engineer Jared Dominguez and enthusiastic feedback. Specs of M3800: 15.6" LCD @ 3840x2160, Intel i7 quad core CPU, NVIDIA Quadro GPU, up to 16 GB RAM. The bad news is, as Dominguez explained on his blog, this version of the M3800 doesn't support its built-in Thunderbolt 2 port out of the box. However, thanks to the hardware-enablement stack in Ubuntu, starting with upcoming Ubuntu 14.04.2, you will be able to upgrade your kernel to add some Thunderbolt support.

How Blind Programmers Write Code 79

Posted by Soulskill
from the one-line-at-a-time dept.
theodp writes: Yes, folks, there are blind programmers. There's Ed Summers, for one, who lost his vision at age 30 and now ghostblogs for Willie the Seeing Eye Dog. And if you've ever wondered how the blind can code, Florian Beijers, who has been blind since birth, explains that all he needs is a normal Dell Inspiron 15r SE notebook and his trusty open source NVDA screen reader software, and he's good-to-go. "This is really all the adaptation a blind computer user needs," Beijers adds, but he does ask one small favor: "If you're writing the next big application, with a stunning UI and a great workflow, I humbly ask you to consider accessibility as part of the equation. In this day and age, there's really no reason not to use the UI toolkits available."

Dell 2015 XPS 13: Smallest 13" Notebook With Broadwell-U, QHD+ Display Reviewed 118

Posted by timothy
from the if-you-can-defy-them-they're-only-guidelines-of-physics dept.
MojoKid writes Dell's 2015 XPS 13 notebook made a splash out at CES this year with its near bezel-less 13-inch QHD+ (3200X1800) display and Intel's new 5th Gen Core series Broadwell-U processor. At 2.8 pounds, the 2015 XPS 13 isn't the absolute lightest 13-inch ultrabook book out there but it's lighter than a 13-inch MacBook Air and only a few ounces heavier than Lenovo's Core M-powered Yoga 3 Pro. The machine's Z dimensions are thin, at .33" up front to .6" at its back edge. However, its 11.98" width almost defies the laws of physics, squeezing a 13.3" (diagonal) display into an 11.98-inch frame making it what is essentially the smallest 13-inch ultrabook to hit the market yet. Performance-wise, this review shows its benchmarks numbers are strong and Intel's Broadwell-U seems to be an appreciable upgrade versus the previous generation architecture, along with lower power consumption.

First Look At Dell Venue 8 7000 and Intel's Moorefield Atom Performance 22

Posted by Soulskill
from the awful-product-names dept.
MojoKid writes: Dell has been strategically setting-up their new Venue 8 7000 tablet for cameo appearances over the past few months, starting back at Intel Developer's Forum in September of last year, then again at Dell World in November and at CES 2015. What's interesting about this new device, in addition to Intel's RealSense camera is its Atom Z3580 quad-core processor, which is based on Intel's latest Moorefield architecture. Moorefield builds upon Intel's Cherrytrail Atom feature set and offers two additional CPU cores with up to a 2.3GHz clock speed, an enhanced PowerVR 6430 GPU and support of faster LPDDR3-1600 memory. Moorefield is also built for Intel's XMM 7260 LTE modem platform, which supports carrier aggregation. Overall, Moorefield looks solid, with performance ahead of a Snapdragon 801 but not quite able to catch the 805, NVIDIA Tegra K1 or Apple's A8X in terms of graphics throughput. On the CPU side, Intel's beefed-up quad-core Atom variant shows well.

Big Names Dominate Open Source Funding 32

Posted by Soulskill
from the all-about-the-open-source-benjamins dept.
jones_supa writes: Network World's analysis of publicly listed sponsors of 36 prominent open-source non-profits and foundations reveals that the lion's share of financial support for open-source groups comes from a familiar set of names. Google was the biggest supporter, appearing on the sponsor lists of eight of the 36 groups analyzed. Four companies – Canonical, SUSE, HP and VMware – supported five groups each, and seven others (Nokia, Oracle, Cisco, IBM, Dell, Intel and NEC) supported four. For its part, Red Hat supports three groups (Linux Foundation, Creative Commons and the Open Virtualization Alliance).

It's tough to get more than a general sense of how much money gets contributed to which foundations by which companies – however, the numbers aren't large by the standards of the big contributors. The average annual revenue for the open-source organizations considered in the analysis was $4.36 million, and that number was skewed by the $27 million taken in by the Wikimedia Foundation (whose interests range far beyond OSS development) and the $17 million posted by Linux Foundation.

Intel 5th Gen Core Series Performance Preview With 2015 Dell XPS 13 97

Posted by Soulskill
from the separating-fact-from-marketing dept.
MojoKid writes: Intel's strategically timed CES 2015 launch of their new 5th Gen Core Series processors for notebooks was met with a reasonably warm reception, though it's always difficult to rise above the noise of CES chatter. Performance claims for Intel's new chip promise major gains in graphics and more modest increases in standard compute applications. However, the biggest bet Intel placed on the new Broadwell-U architecture is performance-per-watt throughput and battery life in premium notebook products that are now in production with major OEM partners. A few manufacturers were early out of the gate with new Core i5 5XXX series-based machines, however, none of the major players caught the same kind of buzz that Dell received, with the introduction of their new XPS 13 Ultrabook with its near bezel-less 13-inch WQHD (3200X1800) display. As expected, the Core i5-5200U in this machine offered performance gains of anywhere from 10 to 20 percent, in round numbers, depending on the benchmark. In gaming and graphics testing is where the new 5200U chip took the largest lead over the previous gen Core i5-4200U CPU, which is one of the most common processors found in typical ultrabook style 13-inch machines.

Ask Slashdot: High-Performance Laptop That Doesn't Overheat? 325

Posted by Soulskill
from the chestnut-roasters dept.
AqD writes: Last year we started to replace business/multimedia-grade laptops with gaming laptops at work, after several years of frustration with overheating and throttling issues that plagued our laptops from Acer, ASUS, Dell, Lenovo, and basically every brand you can find on market, making it impossible to write code and run db/test environment all on the same laptop.

The first new batch comes from Clevo because their gaming laptops don't look like gaming laptops, and they offer 3-6 disk slots which we badly need. The result is acceptable, however, not quite as good as I had expected. Mine has i7-4700mq CPU which is more or less equivalent to an older i7 on the desktop, but its temperature is raised to 70-80C while turbo boost is on, even with the best thermal paste. My friend's i7-4801mq is worse — it could never stay at the advertised 3.6GHz for more than a few seconds before it burns up over 90 and starts to throttle. Its benchmark result is nearly identical to the 4700mq because of heat problems. And it's only 3.6GHz! The best i7 CPU on a desktop could easily run closer to 5GHz with 6 cores / 12 threads running!

So what should we choose next time? We're not looking for something cool or slim or light. We need real laptops which can at least run prime calculation at advertised turbo boost speed, full cores/threads for an entire day. A nice bonus would be manual fan control plus easy access to the fan for cleaning.

LG To Show Off New 55-Inch 8K Display at CES 179

Posted by samzenpus
from the more-k dept.
MojoKid writes One of the most in-your-face buzzwords of the past year has been "4K," and there's little doubt that the forthcoming CES show in early January will bring it back in full force. As it stands today, 4K really isn't that rare, or expensive. You can even get 4K PC monitors for an attractive price. There does remain one issue, however; a lack of 4K content. We're beginning to see things improve, but it's still slow going. Given that, you might imagine that display vendors would hold off on trying to push that resolution envelope further – but you just can't stop hardware vendors from pushing the envelope. Earlier this year, both Apple and Dell unveiled "5K" displays that nearly doubled the number of pixels of 4K displays. 4K already brutalizes top-end graphics cards and lacks widely available video content, and yet here we are looking at the prospect of 5K. Many jaws dropped when 4K was first announced, and likewise with 5K. Now? Well, yes, 8K is on its way. We have LG to thank for that. At CES, the company will be showing-off a 55-inch display that boasts a staggering 33 million pixels — derived from a resolution of 7680x4320. It might not be immediately clear, but that's far more pixels than 4K, which suggests this whole "K" system of measuring resolutions is a little odd. On paper, you might imagine that 8K has twice the pixels of 4K, but instead, it's 4x.

Alienware's Triangular Area-51 Re-Design With Tri-SLI GeForce GTX 980, Tested 138

Posted by timothy
from the where-are-you-priorities dept.
MojoKid writes Dell's Alienware division recently released a radical redesign of their Area-51 gaming desktop. With 45-degree angled front and rear face plates that are designed to direct control and IO up toward the user, in addition to better directing cool airflow in, while warm airflow is directed up and away from the rear of the chassis, this triangular-shaped machine grabs your attention right away. In testing and benchmarks, the Area-51's new design enables top-end performance with thermal and acoustic profiles that are fairly impressive versus most high-end gaming PC systems. The chassis design is also pretty clean, modular and easily servicable. Base system pricing isn't too bad, starting at $1699 with the ability to dial things way up to an 8-core Haswell-E chip and triple GPU graphics from NVIDIA and AMD. The test system reviewed at HotHardware was powered by a six-core Core i7-5930K chip and three GeForce GTX 980 cards in SLI. As expected, it ripped through the benchmarks, though the price as configured and tested is significantly higher.

Android On Intel x86 Tablet Performance Explored: Things Are Improving 97

Posted by Soulskill
from the won't-run-crysis dept.
MojoKid writes: For the past few years, Intel has promised that its various low-power Atom-based processors would usher in a wave of low-cost Android and Windows mobile products that could compete with ARM-based solutions. And for years, we've seen no more than a trickle of hardware, often with limited availability. Now, that's finally beginning to change. Intel's Bay Trail and Merrifield SoCs are starting to show up more in full-featured, sub-$200 devices from major brands. One of the most interesting questions for would-be x86 buyers in the Android tablet space is whether to go with a Merrifield or Bay Trail Atom-based device. Merrifield is a dual-core chip without Hyper-Threading. Bay Trail is a quad-core variant and a graphics engine derived from Intel's Ivy Bridge Core series CPUs. That GPU is the other significant difference between the two SoCs. With Bay Trail, Intel is still employing their own graphics solution, while Merrifield pairs a dual-core CPU with a PowerVR G6400 graphics core. So, what's the experience of using a tablet running Android on x86 like these days? Pretty much like using an ARM-based Android tablet currently, and surprisingly good for any tablet in the $199 or less bracket. In fact, some of the low cost Intel/Android solutions out there currently from the likes of Acer, Dell, Asus, and Lenovo, all compete performance-wise pretty well versus the current generation of mainstream ARM-based Android tablets.

But after the great drama of founder Michael Dell taking the company private, the company is following a new path, adding higher-quality (and more expensive) products like the Venue 8 7000, the thinnest tablet on the market today, to its lineup. One analyst notes that "Because they are no longer reporting to Wall Street, they can be more competitive."

Dell Demos 5K Display 204

Posted by Soulskill
from the all-the-pixels dept.
An anonymous reader writes: Even though 4k displays are just making their way into consumer affordability, manufacturers are already pushing beyond. Dell has previewed a computer monitor it calls a "5k" display. The resolution is 5120x2880, stuffing 14,745,600 pixels on a 27" screen. For comparison, that's more than seven times the amount of pixels in a 1920x1080 display. Pixel density is 218 PPI, roughly the same as a 15" Retina MacBook Pro. ExtremeTech suggests, "As far as we're aware, no one is actually making 5120×2880 panels, especially not at 27 inches diagonal – so what we're probably looking at is two 2560x2880 panels squished together as a 'tiled display.'" Unfortunately, it's pricy, expected to cost around $2,500. But hopefully it will help drive 4k display prices even further toward mainstream availability.

Dell's New Alienware Case Goes to Extremes To Prevent Overheating 149

Posted by timothy
from the pvc-and-tape-would-cost-less dept.
MojoKid writes Dell's enthusiast Alienware brand has always stood out for its unique, other-worldly looks (sometimes good, sometimes, not so good) and there's such a thing as taking things to the next level, this might be it. However, there's more to this refresh than just shock value. It's actually a futuristic aesthetic with a rather purposeful design behind it. Today Alienware gave a sneak peek at their completely redesigned Alienware Area 51 desktop system. This refreshed system is unlike any previous Alienware rig you've seen. With a trapezoidal shape to its chassis, Dell-Alienware says you can place the Area-51 against a wall and not have to worry about thermals getting out of the control. That's because there's a controlled gap and a sharp angle to the chassis that ensures only a small part of the system actually rests near the wall, leaving extra room for hot air to escape up and away. This design also offers users easy access to rear IO ports. Despite the unique design, there's plenty of room for high end components inside. The retooled chassis can swallow up to three 300W double-wide full-length graphics cards. It also brings to the table Intel's latest and greatest Haswell-E in six-core or eight-core options, liquid cooled and nestled into Intel's X99 chipset. No word from Dell on the price but the new Area-51 is slated to start shipping in October.

Is "Scorpion" Really a Genius? 391

An anonymous reader writes CBS's upcoming hacker show Scorpion is pitched as based on the real life of Irish 'eccentric genius' Walter O'Brien a.k.a. "Scorpion". Some of the claims made for the real Scorpion are extraordinary. A child prodigy with an IQ of 197, hacking Nasa at age 13, [supplying] Ireland with more Personal Computers than DELL and Gateway together. Searching online I wasn't able to find anything which, for me, clearly backed up any of these (or other) claims. For example, rather than being the sixth fastest programmer in the world in 1993, his team ranked 90th out of 250 teams. Curiously, his degree grade was an ok, but hardly stellar B+ (II-I). Does anyone know anything to back up the genius claims being made about Scorpion?

An anonymous reader writes with news that bogus BGP announcements can be used to hijack work done by cryptocurrency mining pools. Quoting El Reg: Researchers at Dell's SecureWorks Counter Threat Unit (CTU) have identified an exploit that can be used to steal cryptocurrency from mining pools — and they claim that at least one unknown miscreant has already used the technique to pilfer tens of thousands of dollars in digital cash. The heist was achieved by using bogus Border Gateway Protocol (BGP) broadcasts to hijack networks belonging to multiple large hosting companies, including Amazon, Digital Ocean, and OVH, among others. After sending the fake BGP updates miners unknowingly contributed work to the attackers' pools.

Dell Starts Accepting Bitcoin 152

from the strength-in-numbers dept.
An anonymous reader writes: Mainstream retail companies have been slow to adopt Bitcoin, perhaps skeptical of its long-term value or unwilling to expend the effort required to put a payment system into place. Today, Bitcoin adoption got a momentum boost with Dell's announcement that it will accept Bitcoin as a payment method. Dell is by far the biggest company to start accepting Bitcoin. It's interesting to note that Dell, like many of the larger companies interacting with Bitcoin right now, is doing so through a third-party payment processor. On one hand, it's good — we don't necessarily want each company building their own implementation and possibly screwing it up. On the other hand, it scales back slightly the decentralized and fee-less nature of Bitcoin, which are important features to many of its supporters.

IPMI Protocol Vulnerabilities Have Long Shelf Life 62

Posted by samzenpus
from the protect-ya-neck dept.
msm1267 (2804139) writes "If enterprises are indeed moving services off premises and into the cloud, there are four letters those companies' IT organizations should be aware of: IPMI. Short for Intelligent Platform Management Interface, these tiny computers live as an embedded Linux system attached to the motherboards of big servers from vendors such as IBM, Dell and HP. IPMI is used by a Baseboard Management Controller (BMC) to manage Out-of-Band communication, essentially giving admins remote control over servers and devices, including memory, networking capabilities and storage. This is particularly useful for hosting providers and cloud services providers who must manage gear and data in varied locations.

Noted researchers Dan Farmer, creator of the SATAN vulnerability scanner, and HD Moore, creator of Metasploit, have been collaborating on research into the vulnerabilities present in IPMI and BMCs and the picture keeps getting uglier. Last July, Farmer and Moore published some research on the issue based upon work Farmer was doing under a DARPA Cyber Fast Track Grant that uncovered a host of vulnerabilities, and Internet-wide scans for the IPMI protocol conducted by Moore. Farmer released a paper called 'Sold Down the River,' in which he chastises big hardware vendors for ignoring security vulnerabilities and poor configurations that are trivial to find and exploit."
