      • AnandTechSPEC Adds Linux Edition of SPECviewperf 2020 v3.0 Benchmark

        The SPEC Graphics Performance Characterization (SPECgpc) group updated the Windows version of the workstation GPU benchmark suite - SPECviewperf 2020 - twice last year. The intent of the benchmark is to replay GPU workload traces from real-world professional applications (Maya for media and entertainment, Catia, Creo, NX, and Solidworks for CAD/CAM, OpendTect for the energy industry, and the Tuvok visualization library for rendering medical images). Version 3.0, released in December 2021, updated the Solidworks viewset to better reflect the OpenGL API calls in the latest version of the software. Version 2.0 had enabled selective downloading of the viewsets. While the Windows version of the benchmark had been through three versions, the Linux community was left out, having to rely on the SPECviewperf 13 released almost a decade ago. That is changing today with the availability of the Linux edition of SPECviewperf 2020 v3.0. The benchmark updates the viewsets with traces from the latest versions of the relevant applications and also updates the models to match the Windows version. Since the benchmarks wrapper framework (even for the Windows version) is based on Node-Webkit (now NW.js), the creation of a Linux edition had to mainly deal with the actual viewset processing. Automation and results processing are identical between the Windows and Linux versions.

        Not to be confused with VKD3D-Proton that the Valve team work on, the original vkd3d from the Wine team continues to be updated and a new release is out now. For anyone confused, both of them translate Direct3D 12 to Vulkan. For one thing, Valve is naturally focused only on gaming, which can often come with the drawback of needing the most up to date drivers and not supporting older systems, whereas the Wine team have to support pretty much any software that could run on Windows.

      • HackadayMortal Kombat ROM Hack Kontinues Arcade Legacy | Hackaday

        September 13th 1993, colloquially known as Mortal Monday, became as dividing line in the battle for 16-bit supremacy. The mega popular arcade game Mortal Kombat was ported to Super Nintendo and Sega Genesis consoles, and every fanboy and fangirl had an opinion on which version truly brought the hits. The Super Nintendo version opted to remove the blood and gore in an attempt to preserve the company’s family-friendly image. While the Sega Genesis merely locked the game’s more violent content behind a cheat code that so many fans learned by heart, ABACABB. Nintendo’s decision to censor Mortal Kombat on their console pushed public opinion in favor of the Sega Genesis version being superior, though it was clear that corners were cut in order to squeeze it onto a cartridge. Recently a group of developers led by [Paulo] sought to restore the Genesis version to its full potential with a ROM hack they’re calling Mortal Kombat Arcade Edition.

        • 9 resources to help you contribute to open source in 2022 | Opensource.com

          In 2022, open source is becoming more and more of a household name. But for many years, open source was known as the scrappy underdog of the enterprise IT landscape. Open source has been around for decades in some form or fashion, but it wasn't even until the late 1990s that it was formalized with its name. You may have been using open source technology this whole time but didn't know it. In fact, the website you are currently reading is run on the open source content management system, Drupal. Your car, laptop, smartwatch, and video games are likely supported by Linux, an open source operating system. Red Hat's annual State of Enterprise Open Source was recently released containing a whole lot of insights helpful for anyone growing a career in open source technology. For starters, 77% of IT leaders have a more positive perception of enterprise open source than they did a year ago and 82% of IT leaders are more likely to select a vendor who contributes to the open source community. This means that participating in open source is more important than ever before. Now is the time to advance your open source journey, no matter where you are. Here are a few resources to help you along the way.

        • Enterprisers ProjectEnterprise open source: 4 priorities for CIOs

          2022 marks the fourth year Red Hat has sponsored its annual The State of Enterprise Open Source report. With almost 1300 worldwide IT leaders surveyed, this annual survey provides a window into trends and selectively explores new topics of interest. Let’s take a look at some stats from each category. One key trend is the growth of enterprise open source software at the expense of proprietary software. This year, respondents said they expect proprietary software to drop from 45 percent of their organizations’ software to 37 percent in two years, while enterprise open source grows 5 percent to 34 percent – almost overtaking it. (Community-based open source software is expected to chip away at the proprietary share of the mix as well, albeit at a slower rate.)

        • Enterprisers ProjectIT leadership: 3 new rules for hybrid work

          The pandemic will be the zeitgeist for the 21st century. It has shaped how we live, how our children are educated, and of course, how we work. It has also exposed what employees crave most. These wants and needs happen to be one of the driving factors for why employees leave their organizations, especially in today’s new hybrid workplace. A December 2020 SHRM article found that nearly 70 percent of remote workers say they work on the weekends, with 45 percent noting they work more hours weekly than they did prior to going remote. In the hybrid work environment, we are spending extraordinary amounts of time on the job. It can lead to feeling even more burned out and isolated than ever. Couple those feelings with our intrinsic need for connection, belonging, and relationships, and it’s easy to understand why employees leave organizations where they feel disconnected and unappreciated. The hybrid workforce demands a different organization-employee dynamic. Given how siloed we are, these desires for connection, belonging, and relationships are more important than ever. Employees want to feel valued, appreciated, and cared for by their managers and organizations. Today’s employees also want to trust their organizations and managers as well as feel trusted by them.

          OpenStack is dead! A masked man in a black cloak with “public clouds”, “containers” and ”serverless” inscriptions shot OpenStack straight in the heart. OpenStack fell to the ground and with the last moment of strength exclaimed: “Long live open infrastructure”! That could be a headline of a tabloid, would you agree? OpenStack is dead. We’ve all heard about that. It’s gone. It’s abandoned. It’s been dominated by public clouds. The world does no longer need OpenStack. The word only needs containers, serverless or the next cutting-edge technology (whatever it’s going to be). The world doesn’t like OpenStack anymore. OpenStack is an obsolete technology. It is antiquated, passe and definitely no longer sexy. What is the problem then? Well, the problem is that none of these things is real.

        • New ElectronicsAdvantech and Canonical collaborate on Ubuntu pre-loaded embedded solutions

          By certifying Advantech products, Canonical, the publisher of Ubuntu, guarantees up to 10 years of Linux security and update capabilities for users in the AI robotics, industrial manufacturing, and mission-critical application sectors. The two companies have collaborated on the provision of Ubuntu certifications for deployment-ready IoT devices, so that users can save time when configuring/installing the OS on the hardware. Canonical performs tests that confirm industrial-grade standards for the Ubuntu running on the system. These tests also ensure that individual hardware I/O function normally. Once completed, Advantech will issue a comprehensive test report that reduces the hardware and OS validation procedure from ten days to one. Additionally, pre-installed services can save over 30 minutes in lead-time per device. In order to prevent security breaches and maintain system functionality, AIoT developers are required to keep their devices up to date with the latest software. To address this, Canonical and Advantech have certified Ubuntu Core, a transactional version of Ubuntu designed for IoT devices and embedded systems that provides secure boot, full disk encryption, secure device recovery, and over-the-air, transactional software updates through a cloud-based CI/CD (Continuous Integration, Continuous Deployment) service that helps to lower upgrade risks and reduces the need for on-site repair.

      • The Register UKConcern over growing reach of proprietary firmware BLOBs ● The Register

        Vendors of the FOSS hardware and software communities are voicing their concerns about closed-source firmware. Virtually impenetrable BLOBs (Binary Large Objects) in firmware mean it's difficult to be sure exactly what the computer is doing. Assuming the BLOBs are unencrypted, and they usually are, you'll have to break out a disassembler to figure out what the code does, which requires skills and knowledge, and is tedious – especially if the binary is obfuscated. Hardware vendors provide software, too. You can't boot a computer without multiple pieces of code in various flash ROMs – to initialize the processor, the disk drives, and the chips that connect them. As computers get more complex, so does their firmware. More layers of code not only means more potential vulnerabilities, it means they can be hidden from the running OS. This requires blind trust, which is a strong motivator for keeping the source code of such code open. For the very privacy-conscious, there are x86 laptops such as Purism's Librem machines which use the coreboot open-source firmware, which is also used in Chromebooks. It's not only for consumer kit. So does the LinuxBoot firmware for servers, which is backed by Google and Facebook via the Open Compute Project. Despite some controversy, it's working on version 2 of its spec. Both coreboot and LinuxBoot use Intel's FSP (Firmware Support Package) to initialize the hardware.

        Rocket.Chat is one of the best open-source slack alternatives and Nextcloud is an all-in-one collaboration platform. And, they are pretty impressive. This is why we use Rocket.Chat for our internal communication and Nextcloud to manage tasks/documents. Both of them are incredibly useful for what they are capable of. And, now, it looks like Rocket.Chat and Nextcloud are taking things up a notch by developing a native API integration.

      • Get started with Carbonio, an open source collaboration platform

        In recent years, interest in using open source collaboration platforms to enhance business productivity increased. Proprietary software has managed to overwhelm customers with a maze of licensing requirements and pay-to-play features that many companies don't want to manage. On the other hand, open source offers alternatives that give companies the liberty of choice and allow new businesses to enter existing markets easier with more control over upfront costs. There are many choices in open source when selecting collaborative suites. My favorite is the AGPL-licensed Community Edition of Carbonio by Zextras (you may know Zextras from their complementary components for Zimbra Open Source).

        Something that probably unites most Hackaday readers is a love of machines, particularly unique or interesting ones. In the world of aircraft for example, we’ve run several stories about those which push the edges of the size envelope, be they the Hughes Hercules troop carrier, the Scaled Composites Stratolifter space launcher, or the Antonov An-225 Mriya cargo plane. This last machine has been in the news for all the wrong reasons over the last few days, with reports emerging that it may have been destroyed in the fighting around its base at Hostomel near Kyiv. There has been some uncertainty around this news as it has alternately been claimed to have been destroyed or to have miraculously survived, but now a set of photographs have emerged showing what appears to be the An-225 burning in its damaged hangar.
