Oculus Rift: 2015 Launch Unlikely, But Not Impossible 49

Posted by Soulskill
from the is-the-future-here-yet dept.
An anonymous reader writes: Earlier this week during Facebook's 2015 Q1 earnings call, the company seemed to suggest that a 2015 Oculus Rift release date was unlikely. At least, that's what a report about the call from Gamasutra indicated, saying, "It doesn't sound like Oculus will ship the consumer version of its Oculus Rift VR headset this year, or at least not in very large quantities." However, an equity analyst has chimed in to say that the language used during the call shouldn't be interpreted colloquially, concluding that "...there is no information here that rules out Oculus shipping in 2015."

Learn About FIRST's New Embedded Linux Controller (Video) 26

Posted by Roblimo
from the rocking-and-socking-more-powerfully-than-ever dept.
Our interviewee today is Mike Anderson, an adviser to FIRST (For Inspiration and Recognition of Science and Technology) Team 116 at Herndon High School in Virginia. He's here to tell us about the new embedded Linux controller FIRST is using this year. It is apparently a bit short of documentation at this stage, so team 116 and others have been posting what they learn at Chief Delphi, which is 'the' FIRST online discussion forum (and fun to read to keep up with all things FIRST). We've talked about FIRST before. We've taken you to FIRST competitions, and looked behind the scenes at the building of a FIRST robot, and will no doubt keep covering a selection of FIRST activities in the future.

AMD Publishes New 'AMDGPU' Linux Graphics Driver 88

Posted by Soulskill
from the doing-it-right dept.
An anonymous reader writes: AMD has made available its new AMDGPU Linux graphics driver comprised of a brand new DRM/KMS kernel driver, a new xf86-video-amdgpu X11 driver, and modifications to libdrm and Gallium3D. This new AMDGPU driver is designed for supporting AMD's next-generation hardware with no support differences for currently supported Radeon GPUs. While yet to be released, this new AMDGPU driver is the critical piece to the new unified driver strategy with Catalyst where their high performance proprietary driver will now become limited to being a user-space binary component that uses this open-source kernel driver.

Exploit For Crashing Minecraft Servers Made Public 118

from the hey-fellas-door's-unlocked dept.
An anonymous reader writes "After nearly two years of waiting for Mojang to fix a security vulnerability that can be used to crash Minecraft servers, programmer Ammar Askar has released a proof of concept exploit for the flaw in the hopes that this will force them to do something about it. "Mojang is no longer a small indie company making a little indie game, their software is used by thousands of servers, hundreds of thousands people play on servers running their software at any given time. They have a responsibility to fix and properly work out problems like this," he noted." Here is Askar's own post on the exploit, and his frustration with the response he's gotten to disclosing it to the developers.

jones_supa writes: The KDE project today announced the release of KDE Plasma 5.3 beta. It brings better power management, improved Bluetooth support, improved widgets, Wayland support, new media center, and nearly 350 bugfixes. The power management improvements include settings that can be independently configured per activity, there is a new energy usage monitor available in KInfoCenter, and a battery applet identifies applications that hog power. Bluetooth applet brings added support for blocking and unblocking devices. New touchpad module has been added as well. The combined window manager and compositor KWin is now able to start a nested XWayland server, which acts as a bridge between the old X11 and the new Wayland world.

NVIDIA's New GPUs Are Very Open-Source Unfriendly 309

Posted by Soulskill
from the returning-to-par dept.
An anonymous reader writes: The Nouveau driver developers working on open-source support for the GeForce 900 Maxwell graphics cards have found this new generation to be "very open-source unfriendly" and restricting. NVIDIA began requiring signed firmware images, which they have yet to provide to Nouveau developers, contrary to their earlier statements. The open-source developers have also found their firmware signing to go beyond just simple security precautions. For now the open-source NVIDIA driver can only enable displays with the GTX 900 series without any hardware acceleration.

New Horizons Captures First Color Image of Pluto and Charon 78

192_kbps writes: NASA published today the first color image of Pluto and Charon captured by the New Horizons probe, revealing a reddish world. "The fastest spacecraft ever launched, New Horizons has traveled a longer time and farther away - more than nine years and three billion miles - than any space mission in history to reach its primary target. Its flyby of Pluto and its system of at least five moons on July 14 will complete the initial reconnaissance of the classical solar system. This mission also opens the door to an entirely new "third" zone of mysterious small planets and planetary building blocks in the Kuiper Belt, a large area with numerous objects beyond Neptune's orbit." The picture is blurry, but far better than the few pixels Hubble can resolve, the image whets the appetite for New Horizon's closest approach on July 14th."

from the spreading-like-bamboo dept.
An anonymous reader writes Are the days of Microsoft's proprietary compiler over? Microsoft has announced they've started work on a new .NET compiler using LLVM and targets their CoreCLR — any C# program written for the .NET core class libraries can now run on any OS where CoreCLR and LLVM are supported. Right now the compiler only supports JIT compilation but AOT is being worked on along with other features. The new Microsoft LLVM compiler is called LLILC and is MIT-licensed.

Linux Getting Extensive x86 Assembly Code Refresh 209

Posted by Soulskill
from the code-run-through-de-spaghettifier dept.
jones_supa writes: A massive x86 assembly code spring cleaning has been done in a pull request that is to end up in Linux 4.1. The developers have tried testing the code on many different x86 boxes, but there's risk of regression when exposing the code to many more systems in the days and weeks ahead. That being said, the list of improvements is excellent. There are over 100 separate cleanups, restructuring changes, speedups and fixes in the x86 system call, IRQ, trap and other entry code, part of a heroic effort to deobfuscate a decade old spaghetti assembly code and its C code dependencies.

Linux 4.0 Kernel Released 172

Posted by samzenpus
from the brand-new dept.
An anonymous reader writes "The Linux 4.0 kernel has been released. Linux 4.0 brings many features including live patching, Radeon DisplayPort Audio, RadeonSI fan control improvements, new OverlayFS functionality, Intel Quark SoC support, and a heck of a lot more. Linus's release announcement reads in part: "So I decided to release 4.0 as per the normal schedule, because there really weren't any known issues, and while I'll be traveling during the end of the upcoming week due to a college visit, I'm hoping that won't affect the merge window very much. We'll see. Linux 4.0 was a pretty small release both in linux-next and in final size, although obviously 'small' is all relative. It's still over 10k non-merge commits. But we've definitely had bigger releases (and judging by linux-next v4.1 is going to be one of the bigger ones)."

Supernovae May Not Be Standard Candles; Is Dark Energy All Wrong? 199

Posted by Soulskill
from the either-that-or-it-isn't dept.
StartsWithABang writes: The accelerated expansion of the Universe — and hence, dark energy — was discovered by taking the well-understood phenomenon of type Ia supernovae and measuring them out to great distances. The results indicated that they were fainter than expected, and hence more distant, and hence the Universe's expansion must be accelerating. But new results have just come out, showing that supernovae may not be standard after all. Does this mean dark energy may not be real, or that it may just be slightly weaker than we previously thought?

Nokia Networks Demonstrates 5G Mobile Speeds Running At 10Gbps Via 73GHz 55

Posted by timothy
from the that-is-one-packed-headline dept.
Mark.JUK writes The Brooklyn 5G Summit appears to have provided a platform for Nokia Networks to demo a prototype of their future 5G (5th Generation) mobile network technology, which they claim can already deliver data speeds of 10 Gigabits per second using millimeter Wave (mmW) frequency bands of 73GHz. The demo also made use of 2×2 Multiple-Input and Multiple-Output (MIMO) links via single carrier Null Cyclic Prefix modulation and frame size of 100 micro seconds, although crucially no information about the distance of this demo transmission has been released and at 73GHz you'd need quite a dense network in order to overcome the problems of high frequency signal coverage and penetration.

US Blocks Intel From Selling Xeon Chips To Chinese Supercomputer Projects 229

Posted by Soulskill
from the demands-recall-of-intel-inside-stickers-too dept.
itwbennett writes: U.S. government agencies have stopped Intel from selling microprocessors for China's supercomputers, apparently reflecting concern about their use in nuclear tests. In February, four supercomputing institutions in China were placed on a U.S. government list that effectively bans them from receiving certain U.S. exports. The institutions were involved in building Tianhe-2 and Tianhe-1A, both of which have allegedly been used for 'nuclear explosive activities,' according to a notice (PDF) posted by the U.S. Department of Commerce. Intel has been selling its Xeon chips to Chinese supercomputers for years, so the ban represents a blow to its business.

Stack Overflow 2015 Developer Survey Reveals Coder Stats 428

Posted by Soulskill
from the nobody-loves-matlab dept.
SternisheFan points out the results from 26,086 developers who answered Stack Overflow's annual survey. It includes demographic data, technology preferences, occupational information, and more. Some examples: The U.S. had the most respondents, followed by India and the UK, while small countries and several Nordic ones had the most developers per capita. The average age of developers in the U.S. and UK was over 30, while it was 25 in India and 26.6 in Russia. 92.1% of developers identified as male. Almost half of respondents did not receive a degree in computer science.

The most-used technologies included JavaScript, SQL, Java, C#, and PHP. The most loved technologies were Swift, C++11, and Rust, while the most dreaded were Salesforce, Visual Basic, and Wordpress. 20.5% of respondents run Linux more than other OSes, and 21.5% rely on Mac OS X. Vim is almost 4 times more popular than Emacs, and both are used significantly less than NotePad++ and Sublime Text.

45% of respondents prefer tabs, while 33.6% prefer spaces, though the relationship flips at higher experience levels. On average, developers who work remotely earn more than developers who don't. Product managers reported the lowest levels of job satisfaction and the highest levels of caffeinated beverages consumed per day.

merbs writes: In just a few years, we could see the mass proliferation of DIY, smartphone-enabled replicators. At least, Caltech electrical engineering professor Ali Hajimiri and his team of researchers thinks so. They've developed a very tiny, very powerful 3D imager that can easily fit in a mobile device, successfully tested its prowess, and published the high-res results (PDF) in the journal Optics. Hajimiri claims the imager may soon allow consumers to snap a photo of just about anything, and then, with a good enough 3D printer, use it to create a real-life replica "accurate to within microns of the original object."

Visual Studio 2015 Can Target Linux; Android Apps Anywhere Chrome Can Run 96

Posted by timothy
from the then-you-win-maybe dept.
jones_supa writes Phoronix has noticed that the Visual Studio 2015 product page mentions that the new IDE can target Linux out of the box. Specifically the page says "Build for iOS, Android, Windows devices, Windows Server or Linux". What this actually means is not completely certain at this point, but it certainly laces nicely with the company opening up the .NET Framework. And speaking of cross-platform software: new submitter mccrew writes Google has released a tool that lets Android apps run on any machine that can run its Chrome browser. Called Arc Welder, the tool acts as a wrapper around Android apps so they can run on Windows, OS X and Linux machines. The software expands the places that Android apps can run and might make it easier for developers to get code working on different machines.

Book Review: Drush For Developers, 2nd Edition 29

Posted by samzenpus
from the read-all-about-it dept.
Michael Ross writes As with any content management system, building a website using Drupal typically requires extensive use of its administrative interface, as one navigates through its menus, fills out its forms, and reads the admin pages and notifications — or barely skims them, as they have likely been seen by the site builder countless times before. With the aim of avoiding this tedium, speeding up the process, and making it more programmatic, members of the Drupal community created a "shell" program, Drush, which allows one to perform most of these tasks on the command line. At this time, there is only one current print book that covers this tool, Drush for Developers, Second Edition, which is ostensibly an update of its predecessor, Drush User's Guide. Read below for the rest of Michael's review.
