Canonical Launches Ubuntu 18.04 LTS

Ubuntu 18.04 LTS - the newest version of the most widely used Linux for workstations, cloud and IoT, is now available. "Multi-cloud operations are the new normal" said Mark Shuttleworth, CEO of Canonical and founder of Ubuntu. "Boot-time and performance-optimized images of Ubuntu 18.04 LTS on every major public cloud make it the fastest and most efficient OS for cloud computing, especially for storage and compute-intensive tasks like machine learning."

Kubeflow, the Google approach to TensorFlow on Kubernetes, and a range of CI/CD tools are integrated in Canonical Kubernetes and aligned with Google GKE for on-premise and on-cloud AI development."Having an OS that is tuned for advanced workloads such as AI and ML is critical to a high velocity team" said David Aronchick, Product Manager, Cloud AI at Google. "With the release of Ubuntu 18.04 LTS and Canonical's collaborations to the Kubeflow project, Canonical has provided both a familiar and highly performant operating system that works everywhere. Whether on-premise or in the cloud, software engineers and data scientists can use tools they are already familiar with, such as Ubuntu, Kubernetes and Kubeflow, and greatly accelerate their ability to deliver value for their customers."

Feral Interactive Introduces GameMode Tool for Linux Gamers to Optimize Gaming Performance

Feral Interactive has released their free, open-source tool called GameMode to help Linux gamers squeeze every drop of gaming performance out of their systems. GameMode is basically a small daemon and library combo that instructs the processor to run in Performance Mode when a user is playing a game. GameMode along with the instructions for installation can be found at GitHub. Feral Interactive also took the opportunity to announce that Rise of the Tomb Raider, which lands on Linux later this month, will be the first Linux title to integrate GameMode. Future titles from the video game publisher will probably include GameMode as well.

Compulab Intros Mintbox Mini 2 PC based on Linux Mint

Compulab rolled out the Mintbox Mini 2, a smaller version of the Mintbox 2 the company rolled out way back in 2013. The Mintbox Mini 2 is based almost entirely on the Compulab Fitlet 2 mini-PC, but with Linux Mint with all device drivers pre-installed, and some exclusive branding. This box is based on the slightly older Intel Celeron J3455 SoC with embedded Intel HD Graphics 500 (and not the latest Celeron J4005). It's still claimed to be close to twice as fast as the AMD A4-6400T-based original. Besides the SoC, the storage specs appear to be identical - 4 GB RAM, 64 GB storage, but there are improvements on some fronts - dual-band 802.11ac + Bluetooth 4.2 WLAN (as opposed to 802.11 b/g/n on the original), and two wired GbE interfaces instead of just one. The Mintbox Mini 2 is priced at USD $299, just $4 more than the original Mintbox Mini, but a staggering $146 higher than the Fitlet 2. This is not because of the OS, but pre-installed RAM, storage, and WLAN module.

Rise of the Tomb Raider: 20 Year Celebration Comes to macOS & Linux This Spring

Intel's Patch for Meltdown, Spectre "Complete and Utter Garbage:" Linus Torvalds

Linus Torvalds, creator of Linux, the most popular datacenter operating system, proclaimed Intel's patches for the recent Meltdown and Spectre CPU vulnerabilities "complete and utter garbage." Torvalds continues to work on the innermost code of Linux, and has been closely associated with kernel patches that are supposed to work in conjunction with updated CPU microcode to mitigate the two vulnerabilities that threaten to severely compromise security of data-centers and cloud-computing service providers.

Torvalds, in a heated public chain-mail with David Woodhouse, an Amazon engineer based out of the UK, called Intel's fix "insane" and questioned its intent behind making the patch "toggle-able" (any admin can disable the patch to a seemingly cataclysmic vulnerability, which can bring down a Fortune 500 company). Torvalds also takes issue with redundant fixes to vulnerabilities already patched by Google Project Zero "retpoline" technique. Later down in the thread, Woodhouse admits that there's no good reason for Intel's patches to be an "opt-in." Intel commented on this exchange with a vanilla-flavored potato: "We take the feedback of industry partners seriously. We are actively engaging with the Linux community, including Linus, as we seek to work together on solutions."

Intel Secretly Firefighting a Major CPU Bug Affecting Datacenters?

There are ominous signs that Intel may be secretly fixing a major security vulnerability affecting its processors, which threatens to severely damage its brand equity among datacenter and cloud-computing customers. The vulnerability lets users of a virtual machine (VM) access data of another VM on the same physical machine (a memory leak). Amazon, Google, and Microsoft are among the big three cloud providers affected by this vulnerability, and Intel is reportedly in embargoed communications with engineers from the three, to release a software patch that fixes the bug. Trouble is, the patch inflicts an unavoidable performance penalty ranging between 30-35%, impacting the economics of using Intel processors versus AMD ones.

Signs of Intel secretly fixing the bug surfaced with rapid changes to the Linux kernel without proper public-visibility of the documentation. The bulk of the changes involve "kernel page table isolation," a feature that prevents VMs from reading each other's data, but at performance costs. Developers note that these changes are being introduced "very fast" by Linux kernel update standards, and even being backported to older kernel versions (something that's extremely rare). Since this is a hardware vulnerability, Linux isn't the only vulnerable software platform. Microsoft has been working on a Windows kernel patch for this issue since November 2017. AMD x86 processors (such as Opteron, Ryzen, EPYC, etc.,) are immune to this vulnerability.

Zorloo Announces Their Second-Generation Portable USB-DAC

Zorloo is pleased to introduce its second-generation portable USB-DAC product, ZuperDAC-S, today. It builds on its wildly praised ZuperDAC to enable computers or mobile phones an unprecedented HiFi music experience. Today, computers and mobile phones are powerful enough to handle different audio protocols. However, the last but most critical step in the entire digital-to-analog conversion process, i.e. turning musical data 0 and 1 into audible sound waves, always sucks. Constrained by the limitation of this internal conversion process, audio may also have to be re-sampled to fit the pipeline.

Bypassing the internal conversion with ZuperDAC-S drastically improves sound quality to a new level. It supports up to 192kHz sampling frequency and 24-bit depth, which eliminates unnecessary sample rate and bit depth conversion. The music output from ZuperDAC-S is exactly what was recorded. ZuperDAC-S uses the ESS Sabre 9018 audiodac and delivers a stunning 120dB SNR and 0.0005% THD+N performance. It delivers a balanced, clear and articulated sound in a wide soundstage. The integrated headphone amplifier output can connect directly to headphones, or go through the amplifier systems.

AMD Releases AMDVLK - Open-Source Vulkan Driver for Linux

AMD released the AMDVLK drivers for Linux. These are the first open-source AMD Radeon graphics drivers featuring 100% support for Vulkan 1.0 graphics API. The drivers include Vulkan 1.0 compliance with support for 30 Vulkan extensions, Radeon GPU Profiler support, in-built debug and profiling tools, mid-command buffer preemption, and SR-IOV virtualization support. AMDVLK implements AMD's Platform Abstraction Library (PAL), an abstraction layer that translates much of AMD's common driver code and features across platforms. The drivers support all AMD Radeon GPUs based on the Graphics CoreNext architecture, going all the way back to the Radeon HD 7000-series. The drivers are released through AMD's GPUOpen GitHub repository.

NVIDIA to End Support for 32-bit Operating Systems After R390 Drivers

NVIDIA announced that it is ending driver support for 32-bit operating systems after its R390-series drivers. Following its GeForce 390.xx release, NVIDIA will not support 32-bit versions of Windows 10, Windows 7, Windows 8/8.1, Linux, or FreeBSD for any of its GPU architectures. NVIDIA will, however, offer support for critical driver security fixes for 32-bit operating systems until January 2019. This means the company will release hotfixes addressing specific critical security vulnerabilities in the drivers, as and when they're found, but such hotfixes won't include new features or optimizations that are part of the main driver trunk for 64-bit operating systems.

AMD Navi Found Secretly Hiding in Linux Drivers

We know AMD has been doing a great job keeping the lid on their Navi architecture with information being scarce at the moment. Aside from knowing that Navi is being fabricated on the 7 nm process, it is possible that the microarchitecture will quite possibly support next-generation memory like GDDR6 or HBM3. In a Navi discussion on the Beyond3D forums, a user found an entry in a Linux driver dated back to July that apparently mentions AMD's upcoming architecture - not by its real name, of course. The code is to add support for importing new asic definitions from a text file as opposed to adding support in code. Tom St Denis, a software engineer at AMD, listed the output that would be generated by using this functionality. However, the entry that caught our attention reads: new_chip.gfx10.mmSUPER_SECRET.enable [0: 0]. If our memory serves us right, the codename for Vega was GFX9. So by logic, Navi should carry the GFX10 codename. Obviously, the SUPER_SECRET part further backs up our theory or maybe AMD's just trolling us. The red team has been hiring personnel for their GFX10 projects, so we can assume they're working diligently to release Navi some time next year.

Latest Steam Client Beta Introduces Shader Pre-Caching for Games

The latest update for the Steam software brought with it an important new addition for the quality of life of gamers under the Linux or Windows suns everywhere: persistent shader caches for games. In the latest change-log, users are treated to the following message: "New feature: Shader Pre-Caching. Whenever possible, depending on hardware and driver support, Steam can download pre-compiled shaders for your specific video card. This reduces load times and in-game stuttering during the first few launches of OpenGL- and Vulkan-based games on supported hardware. This feature may use a small amount of additional bandwidth as Steam uploads and analyzes a shader usage report after each run of the game. The feature can be disabled via a new entry in the Settings dialog.

Under Steam Settings, you'll find a new Shader Pre-Caching item. The description reads as follows: "Shader Pre-Caching allows Steam to download pre-compiled GPU shaders matching your system configuration. This allows Vulkan and OpenGL games to load faster and improve framerate stability during gameplay. If enabled, Steam will collect shaders from your system when needed. Enabling this feature may slightly increase disk and bandwidth usage."

MINIX Creator Andrew Tanenbaum Sends Open Letter to Intel Over MINIX Drama

We recently reported about MINIX, the hidden Unix-like OS that Intel was secretly shipping in all of their modern processors. This came as a shock to most of us and to MINIX creator Andrew Tanenbaum as well. Although Andrew wasn't completely surprised by the news, since Intel approached him couple years back asking him to make a few changes to the MINIX system. He stated in the open letter that he wasn't looking for economic remuneration, but it would have been nice if Intel had told him about their plans to distribute his operating system in their processors.

Taking Hold of Your Signal - Critical Flaw Discovered in WPA2 Wi-Fi Security

Researchers have recently discovered a critical flaw that affects all WPA2 protected Wi-Fi devices. This can't be remedied solely by user intervention, or password changes, or even by the usage of HTTPS website; this is a flaw with the core of WPA's protection scheme, and means that an attacker could intercept every single traffic data point that your device sends over Wi-Fi, including passwords, credit card details, images - the whole treasure trove. Adding insult to injury, it's even possible for attackers using this method to inject malware into your devices. The new attack method - dubbed KRACK for Key Reinstallation Attack - basically forces your device's encryption code to default to a known, plain-text all-zero decryption key, which is trivial for hackers to reuse.

Adding to the paranoia, this is basically a device and software-agnostic attack - it's effective against devices running Android, Linux, and OpenBSD, and to a lesser extent macOS and Windows, as well as MediaTek Linksys, and other types of devices. HTTPS isn't the best solution either, simply because some website's implementation of it isn't the best, and there are scripts (such as SSLScript) that can force a website to downgrade its connection to a simple HTTP link - which can then be infiltrated by the attacker.

AMD Resolves Linux Marginality Performance Issue on Newly Shipped Ryzen CPUs

We've brought to your attention how AMD's Ryzen architecture was encountering a bug that prevented it from successfully performing certain tasks under Linux. The issue, to which Phoronix was the first website to call attention to, was later confirmed by AMD, with a further remark from the chip designer that EPYC and ThreadRipper weren't affected by it.

AMD has now solved the Ryzen issue at a silicon level, and new revisions of the CPUs should be clear of the problems. Phoronix's Michael Larabel has confirmed that the new processor passes the previous insurmountable, crash-prone workloads with flying colors, so all in all, AMD delivered a swift response to the issue. The company is also doing good for itself in that it is open to replacing previous-batch CPUs that are affected by the issue, through a contact to its Customer Care department.

AMD Confirms Ryzen Marginality Performance Issue Under Linux, TR and EPYC Clear

An issue on AMD's Ryzen performance under certain Linux workloads, which caused segmentation faults in very heavy, continuous workloads on the Ryzen silicon (parallel compilation workloads in particular) has been confirmed by AMD. Tests like Phoronix's Test Suite's stress run quickly bring the Ryzen processors to their knees with multiple segmentation faults. While this problem is easy to cause under very heavy workloads, the issue is virtually absent under normal Linux desktop workloads and benchmarking,

AMD also confirmed this issue is not present in EPYC or Threadripper processors, but are isolated to early Ryzen samples under Linux (AMD's testing under Windows has found no such behavior.) AMD's analysis has also found that these Ryzen segmentation faults aren't isolated to a particular motherboard vendor, but are problems with the processors themselves. AMD encourages Ryzen customers who believe to be affected by the problem to contact AMD Customer Care. Some of those who have contacted customer care about the segmentation faults have in turn been affected by thermal, power, or other problems, but AMD says they are committed to working with those encountering this performance marginality issue under Linux. AMD will also be stepping up their Linux testing/QA for future consumer products.

Steam Survey Update: It's All About Quad-cores, NVIDIA and Windows 10

An update to the Steam survey results is always worth noting, especially with the added, tremendous growth Valve's online store service has seen recently. And it seems that in the Steam gaming world at least, quad-core CPUs, NVIDIA graphics cards, and Windows 10 reign supreme.

Windows 10 64-bit is the most used operating system, with 50.33% of the survey. That the second most used Windows OS is the steady, hallmark Windows 7 shouldn't come as a surprise, though it does have just 32.05% of the market now. OS X has a measly 2.95% of the grand total, while Linux comes in at an even lower 0.72%. While AMD processor submits may have increased in other software, it seems that at least in Steam, those numbers aren't reflected, since AMD's processor market share in the survey has decreased from 21.89% in February to just 19.01% as of June, even though the company's Ryzen line of CPUs has been selling like hotcakes. Quad-core CPUs are the most used at time of the survey, at 52.06%, while the next highest percentage is still the dual-core CPU, with 42.23%.
