A Republican congressman said the platform didn't crack down on "defamatory" tweets.
HP was one of the many companies that built a virtual reality headset for the Windows Mixed Reality platform which launched back in 2017. Microsoft provided a SteamVR-compatible software platform, controller design, and inside-out, six-axis, positional-tracking technology; hardware companies like HP provided the rest, greatly reducing the price of PC-attached virtual reality.
Today, HP is launching the Reverb Virtual Reality Headset Professional Edition. As the name might imply, the audience for this isn't the consumer space, it's the commercial space. The headset will have a near-identical consumer version, but HP's focus is very much on the pro unit because that's where the company has seen the most solid uptake of VR tech. The big VR win isn't gaming or any other consumer applications: it's visualization, for fields such as engineering, architecture, education, and entertainment, combining VR headsets with motion-actuated seating to build virtual rides. The company has also found that novelty items such as its VR backpack have also found a role in the corporate space, with companies using them to allow free movement around virtual worlds and objects.
Accordingly, HP's second-gen headset is built for these enterprise customers in mind. Their demands were pretty uniform and in many ways consistent with consumer demands, with the big ones being more resolution and more comfort. To that end, it now has a resolution of 2160×2160 per eye, using an LCD with a 90Hz refresh rate. The optics have also been improved through the use of aspherical lenses, for a 114-degree (diagonal) field of view. AMOLED screens are common in this space, but HP said that it preferred LCD because LCD panels use full red, green, and blue subpixels rather than the pentile arrangement that remains common for AMOLED.
The group could not prove that everybody who received its promotional message had consented.

Today, Apple will finally begin taking orders for newly refreshed 21- and 27-inch iMacs. The new versions don't change the basic design or add major new features, but they offer substantially faster configuration options for the CPU and GPU.
The 21.5-inch iMac now has a 6-core, eighth-generation Intel CPU option—up from a maximum of four cores before. The 27-inch now has six cores as the standard configuration, with an optional upgrade to a 3.6GHz, 9th-gen, 8-core Intel Core i9 CPU that Apple claims will double performance over the previous 27-inch iMac. The base 27-inch model has a 3GHz 6-core Intel Core i5 CPU, with intermediate configurations at 3.1GHz and 3.7GHz (both Core i5).
The big news is arguably that both sizes now offer high-end, workstation-class Vega-graphics options for the first time. Apple added a similar upgrade option to the 15-inch MacBook Pro late last year.
Consumer-grade virtual reality (and, to a lesser extent, augmented reality) is only a few years old, but it’s already an extremely fragmented market. Wikipedia lists almost 30 distinct VR headsets released by dozens of hardware makers since 2015. Creating a game that works seamlessly with all of these headsets (and their various runtime environments) can be a headache even for the biggest studios.
OpenXR is out to change all that. With Monday’s release of the OpenXR provisional specification, Khronos’ open source working group wants to create a world where developers can code their VR/AR experience for a single API, with the confidence that the resulting application will work on any OpenXR-compliant headset.
"By accessing a common set of objects and functions corresponding to application life cycle, rendering, tracking, frame timing, and input, which are frustratingly different across existing vendor-specific APIs, software developers can run their applications across multiple XR systems with minimal porting effort—significantly reducing industry fragmentation," Khronos said in a statement announcing the provisional release.
Facebook says 4,000 people viewed the original attack video and fewer than 200 watched it live.
Nothing says "I love diving headfirst into a ditch" like your hair suddenly elevating to the tingly feel of electricity. Thunderstorms are amazing from inside a building, but they're scary if you're trapped outside. And, despite a good deal of observation, an element of mystery surrounds them. For instance, we know that lightning can produce free neutrons, antimatter, and gamma rays, but we don't have much idea of how that happens.
That has partially changed thanks to an Indian muon telescope, called GRAPES-3—a classic example of a backronym. GRAPES-3 is designed to detect muons (a heavier cousin to the electron and positron) that are generated as gamma rays hit the Earth’s atmosphere. It is a relatively simple detector that has the benefit of covering a reasonable chunk of sky with good angular resolution. The detectors are also buried under a thick layer of concrete, so muons need to be quite energetic to get to them.Prediction: Lightning with a chance of telescopes
GRAPES-3 doesn’t actually care where the muons come from; it just happily counts away. Evidently, the scientists running the detector noticed that their data would always go a bit skewiff every time a thunderstorm passed over. Instead of ignoring this, the researchers (while keeping their heads low), installed a set of electric field monitors at various distances from the observatory and started logging electric field strength every time a storm passed over. That data could be easily compared to the muon detection rate. Unsurprisingly, storms are complex beasts, resulting in a lot of data that simply couldn’t be interpreted.
The firm had more orders per week, but their average size was slightly lower.
The Norwegian firm, which employs 35,000 people worldwide, has switched to manual controls at some plants.
SAN FRANCISCO—Unity, one of the leading 3D-rendering systems used to build modern video games, kicked off GDC 2019 with a keynote presentation that took aim at its primary rival, Unreal Engine 4.
"We have no interest in creating experiences that compete with your hobbies or your businesses," Unity CEO John Riccitiello told the keynote's crowd on Monday night. (This was a not-so-subtle dig at how Unreal's creators at Epic Games use their engine to power the mega-popular Fortnite.) "We're here to build the platform that serves you, the developer, and serves you alone."
While the keynote emphasized Unity's affinity for lower-end devices, particularly smartphones, it concluded with an emphasis on the highest-of-end machines: a partnership with Nvidia to bring its proprietary RTX ray tracing pipeline to any Unity video game.
SAN FRANCISCO—Activision has taken the wraps off its first major Call of Duty video game for smartphones. The title is simple enough: Call of Duty Mobile. The online, multiplayer-only game will arrive later this year, but neither Activision nor any of its Western CoD-focused studios will lead the game's development.
Instead, dev duties will be handled by Tencent, one of China's leading mobile-game publishing houses. Activision clarified that Timi Studio, makers of the popular mobile game Arena of Valor, will lead development within Tencent.
Call of Duty Mobile was unveiled at today's Unity keynote presentation as part of the 2019 Game Developer Conference, because it has been built in the Unity Engine. An Activision representative at the Unity event said that players can expect "beloved maps, competitive game modes, and signature combat mechanics from [Call of Duty entries like] Black Ops and Modern Warfare." Teased maps coming to the series' first-ever mobile version include Nuketown, Hijacked, and Crash, and fans can expect traditional CoD multiplayer systems like kill streaks.
As Venezuela staggers under political and economic crises, its citizens are embracing digital money.
On Sunday, Ethiopia's transport minister announced that information recovered from flight data recorders aboard the ill-fated Ethiopian Airlines Flight 302 revealed "clear similarities" to the data from the crash of Lion Air Flight 610 off Indonesia last October. And analysis of the wreckage indicated that the aircraft's control surfaces had put the Ethiopian Airlines Boeing 737 MAX 8 into a dive just before it crashed, killing all aboard.
While the investigation is still underway, the flight data increases the focus on Boeing's Maneuvering Characteristics Augmentation System (MCAS) flight software—software developed to help manage the shifted handling characteristics of the 737 MAX aircraft from other 737s. And that software, it turns out, was originally presented to the Federal Aviation Administration as much less risky than it actually was, which limited FAA oversight.
Now the Transportation Department and Justice Department have launched a new investigation into how Boeing got the initial safety certification for the 737 MAX from the FAA two years ago.
The 55- and 65-inch C-series will ship in April for $2,500 and $3,500, respectively. A 77-inch variant will come a month later in May for $7,000. The E-series will see a staggered launch: the $4,300, 65-inch model will ship in April, but the $3,300, 55-inch will curiously ship a month later in May. Finally, there's the high-end W-series. Those TVs will ship in June, for either $7,000 for a 65-inch model or a whopping $13,000 for 77 inches.
LG's announcement didn't specify a release date for the lower-end B9 model, which will be available in 55- and 65-inch configurations whenever it does arrive. Neither did it mention the rollable TV (dubbed the R series) that made such a splash at CES or the 88-inch, 8K option known as the Z9. All of those TVs are expected this year sometime, but it looks like we'll have to wait a little longer to get final confirmation of release dates and pricing.
On Monday, New Jersey Governor Phil Murphy signed a bill banning cashless retail stores and restaurants in the Garden State. Murphy's signature makes New Jersey the second state in the US to ban cashless stores, after Massachusetts banned them in 1978.
More recently, New Jersey's move follows that of Philadelphia, which banned cashless stores earlier this month. Philadelphia's legislation was a reaction to a growing number of stores that only accept credit cards or require customers to pay with an app, like Amazon's new Amazon Go stores.
Ars contacted Amazon for comment on the new law, but the company did not respond.
President Vladimir Putin has tightened his grip on the Russian Internet Monday, signing two censorship bills into law. One bans "fake news" while the other makes it illegal to insult public officials.
Russia has never really been a liberal democracy. It lacks an independent judiciary, and the government has found a variety of techniques to harass and intimidate independent media in the country.
But the new legislation gives the Russian government more direct tools to censor online speech. Analyst Maria Snegovaya told The Washington Post that the legislation "significantly expands the repressive power of Russia’s repressive apparatus."
In the movies, regeneration is the stuff of superheroes like Deadpool, who regrew the lower half of his body through some seriously awkward transitional scenes. Here in reality, regeneration is run of the mill, with lizards and amphibians regrowing limbs and tails while various worms are able to regrow half their entire body. How they manage this has been the subject of extensive study, and we have a fair idea of some of the genes and processes involved. But it's fair to say we don't have a strong idea of how the whole process is coordinated and directed to form all of the needed tissues.
A step in that direction comes from a recent study that takes a strange angle on regeneration. To understand the process, the authors sequenced the genome of a worm that can regenerate into two full organisms after being cut in half. But the worm also happens to be part of a group that contains the closest living relatives of bilateral animals—those with a left and right side. As such, it could provide a fascinating perspective on our own evolution, but it's something the researchers choose to ignore in this paper.Xena coelo what a?
Most of the animals we're familiar with are bilaterals, which have a left and right side. That includes some creatures (like sea urchins) where the two sides aren't all that obvious. These bilateral animals also start out early in their development as three layers of cells: an outer layer that forms the skin and neural tissue; a central one that forms internal structures like muscles and bone; and an inner layer that goes on to form the lining of the gut.
Mirai, the virulent Internet of Things malware that delivered record-setting denial-of-service attacks in 2016, has been updated to target a new crop of devices, including two found inside enterprise networks, where bandwidth is often plentiful, researchers said on Monday.
The malware infects webcams, routers, DVRs, and other Internet-connected devices, which typically ship with default credentials and run woefully outdated versions of Linux that are rarely, if ever, updated. The rapidly spreading Mirai first made a name for itself in 2016, when it helped achieve record-setting DDoS attacks against KrebsOnSecurity and French Web host OVH.
A newly discovered variant contains a total of 27 exploits, 11 of which are new to Mirai, researchers with security firm Palo Alto Networks reported in a blog post Monday. Besides demonstrating an attempt to reinvigorate Mirai’s place among powerful botnets, the new exploits signal an attempt to penetrate an arena that's largely new to Mirai. One of the 11 new exploits targets the WePresent WiPG-1000 Wireless Presentation systems, and another exploit targets LG Supersign TVs. Both of these devices are intended for use by businesses, which typically have networks that offer larger amounts of bandwidth than Mirai’s more traditional target of home consumers.
One of the more notable features of Google Project Zero's (GPZ) security research has been its 90-day disclosure policy. In general, vendors are given 90 days to address issues found by GPZ, after which the flaws will be publicly disclosed. But sometimes understanding a flaw and developing fixes for it takes longer than 90 days—sometimes, much longer, such as when a new class of vulnerability is found. That's what happened last year with the Spectre and Meltdown processor issues, and it has happened again with a new Windows issue.
Google researcher James Forshaw first grasped that there might be a problem a couple of years ago when he was investigating the exploitability of another Windows issue published three years ago. In so doing, he discovered the complicated way in which Windows performs permissions checks when opening files or other secured objects. A closer look at the involved parts showed that there were all the basic elements to create a significant elevation of privilege attack, enabling any user program to open any file on the system, regardless of whether the user should have permission to do so. The big question was, could these elements be assembled in just the right way to cause a problem, or would good fortune render the issue merely theoretical?
The basic rule is simple enough: when a request to open a file is being made from user mode, the system should check that the user running the application that's trying to open the file has permission to access the file. The system does this by examining the file's access control list (ACL) and comparing it to the user's user ID and group memberships. However, if the request is being made from kernel mode, the permissions checks should be skipped. That's because the kernel in general needs free and unfettered access to every file.
