  • Linux 5.4.7 / 4.19.92 / 4.14.161 Bringing The AMD MCE Fix For New Threadripper CPUs

    With the recently launched Threadripper 3960X / 3970X processors there was a workaround needed to boot them on Linux until an AMD MCE driver issue was resolved. That patch was upstreamed last week into the Linux 5.5 development kernel while now is getting ready to make its debut into supported Linux stable release branches.

    Getting back onto his stable kernel maintenance duties now that Christmas week has passed, Greg Kroah-Hartman sent out his hundreds of patches back-ported for the Linux 5.4 / 4.19 LTS / 4.14 LTS stable series he oversees. Besides the kernel mailing list, the hundreds of patches queued for the next point releases in those branches can be seen via linux-stable-rc.git. Catching my eye from those patches is that the AMD MCE fix for the newer processors is indeed part of the queues for all three stable series.

  • X.Org Saw A Lot Of Work In The 2010s Even With Wayland Taking Off

    Here's a look back at the most popular news over the past decade on X.Org out of our one thousand plus articles on the topic during the 2010s. Even with Wayland taking off in recent years and effectively reaching parity to the X.Org Server for common use-cases, the X.Org Server has continued seeing new development especially in the areas of GLAMOR and XWayland. Sadly though we're ending the 2010s without a major stable release of the xorg-server since May 2018.

  • A peek at how many of the most popular games on Steam support Linux, December 2019 edition

    As the 2010s come to a close, let's look over a few different ways of looking at how many popular games are available on Linux as of December 2019.

    Inspired by an article I did in January this year, back then when looking at the Steam 250 website we had 132 out of 250 of the best reviewed games available on Linux. Right now though? How much has changed in the space of almost one year?

    Not a whole lot actually! 125 in the top 250 are available on Linux. That's still a really great amount of games, especially since these are all games that have a seriously great user rating. This includes some awesome titles like: Portal 2, Terraria, Factorio, Stardew Valley, Euro Truck Simulator 2, Left 4 Dead 2 and The Binding of Isaac: Rebirth.

  • Suse Marks Nine Years Of Continuous Growth With Successful FY2019

    Suse heralded its ninth consecutive year of revenue growth, announcing financial results and highlights from its fiscal year 2019 ended Oct. 31.
    Having become the world’s largest independent open source company earlier this year, Suse saw its application delivery subscription revenue jump 299 percent year over year. In addition, cloud revenue increased 64 percent, driven by cloud providers like Amazon Web Services, Google Cloud and Microsoft Azure, as Suse’s Cloud Service Provider ecosystem grew exponentially.

    Customer deals valued at $1 million or more increased 13 percent, contributing to a double-digit jump in revenue. As growth accelerated, Suse’s employee base grew 11 percent.

  • Ubuntu 13.04 vs. Ubuntu 20.04 Development Performance Comparison Without Mitigations

    Last week I posted benchmarks looking at seven years of Ubuntu Linux performance in re-testing the releases of Ubuntu 13.04 through Ubuntu 19.10 stable and even the latest Ubuntu 20.04 LTS daily development image. A question that came up was how much better that performance would have been without any CPU vulnerability mitigations in place for Ubuntu 20.04... Well, here's that answer.

    In this article are the Ubuntu 13.04, Ubuntu 19.10, and Ubuntu 20.04 daily benchmark results from that earlier article plus an additional run now after re-testing Ubuntu 20.04 when the kernel was booted with "mitigations=off" for getting an idea of the performance lost due to the various in-kernel mitigations over the past nearly three years.

  • Modernization of OSS/BSS with Open Source, Part 3: Integration

    To realize the agility and velocity that have become imperatives in the market environment today, communications service providers (CSPs) must transform their service delivery and management infrastructure. This means that the systems that underpin their network and service operations must evolve. These are the operations support systems (OSS) that enable the operator to manage the network and the business support systems (BSS) that facilitate the management of the customer and overall business operations.

    [...]

    CSPs’ need for agility and velocity to compete creates requirements for constant integration as the overall OSS/BSS environment evolves piece by piece, leading vendors, systems integrators, and CSPs themselves to adopt new open-source solutions for agile integration. Adopting API led design with new software development methodologies benefits developers with shorter development times and less testing, users with faster implementation of new features and functionality, and business owners with increased business agility. Adopting standard open-source platforms across the business provides a homogeneous technology base, allowing for faster, more reliable feature development at scale. Red Hat Integration and Red Hat OpenShift solutions are ideally suited to the iterative modernization journey for OSS and BSS.

  • Narrative to open source its codebase, seeks to sell business

    Narrative has announced that it will open-source its codebase and explore the sale of its platform following the early December announcement of its closure. Narrative cited market events, regulatory uncertainty, and limited resources as the leading factors in the project shutdown.

    Effective immediately upon the closure announcement, no new content, posts, comments, or quality ratings were accepted on the Narrative platform.

    [...]

    Narrative is opting open source its codebase using the GPL v3.0 license, which is a free, copyleft license for software and other kinds of works that aims to ensure the software is free for all its users.

  • SD Times Open-Source Project of the Week: Falcon

    This week’s highlighted project is Falcon, which is an open-source Python framework for building large-scale app backends and microservices.

    According to the Falcon maintainers, the framework encourages the REST architectural style. It also attempts to do as little as possible, while also remaining highly efficient.

    “When it comes to building HTTP APIs, other frameworks weigh you down with tons of dependencies and unnecessary abstractions. Falcon cuts to the chase with a clean design that embraces HTTP and the REST architectural style,” the Falcon documentation states.

  • 5 Pivotal Events in IoT and Embedded

    Key themes in the embedded systems and Internet of things (IoT) world this year range from edge intelligence to security and the progress of open source. Below, we share what we see as the top five pivotal events from 2019 that are likely to have significant ramifications on 2020.

    [...]

    While governments around the world are increasingly considering security guidelines for connected devices, January 2020 will see California’s Senate Bill, SB 327, come into enforcement. This requires manufacturers of connected devices for sale in California to equip the devices with ‘reasonable’ security features.

    Hence the announcement of OpenTitan, an open source silicon root of trust, is viewed as critical. The move will make it easier for developers to design trusted security into their systems at the metal level. We see this likely to be a pivotal moment for embedded security and IoT.

  • Scylla Summit 2019

  • Move over Edge: Safari looks to be jumping on the Chromium bandwagon, too [Ed: Any monoculture around proprietary software is a bad thing]

    UPDATE: According to some traffic over on Twitter, it looks like this whole thing is vaporware. It has been uncovered that the bug in question in the article below has nothing to do with Safari at all. The bug is still private and cannot be viewed by non-Google employees, but it appears that this bug is assigned to “Move sync tests to staging” from 2015. We’re sorry for the incorrect reporting and have left the original story below. Additionally, here is a tweet from someone more informed than me on the subject:

  • Rumor: Apple could transition Safari to Google’s open-source Chromium platform

    Update: The following rumor has since been debunked by the original reporter, Chrome Unboxed. That has also been backed up by an email exchange from Apple.

    It appears that Apple’s flagship web browser may join its competitors on the Chromium-based browser trend. At least, if recent screenshots are to be believed.

    According to a recently published (and Google translated) bug report from iPhones.ru, there may be reason to believe that Apple is moving towards developing a version of Safari that is based on the open-source Chromium platform. The report, which includes screenshots from reader Artyom Pozharov, details a discovery made by Pozharov while browsing Chromium Monorail, Google’s bug tracking site.

  • Future of Siri, Alexa and Google Home with open-source smart home standards [Ed: The grotesque openwashing of mass surveillance inside people's homes]

    Building a smart home isn't as difficult anymore. However, making devices from different brands talk to each other can get difficult at times. With the new Project CHIP - Amazon, Apple, Google, and Zigbee Alliance aim to build an open-source smart home standard that can finally help consumers set up their preferred control system without being ruled over by brands.

  • Apple and Google collaborate to develop open-source smart home standard [Ed: The openwashing of surveillance has become a big thing]

    Apple, Google, and Amazon are set to form a partnership to develop an open-source smart home standard that will make sure devices work together, simplify the development of new devices, and keep everything safe in the process.

  • Open Source Medicine And Cannabinoids: A Promising Future

    Entire industries are now being built around tetrahydrocannabinol (THC) and cannabidiol (CBD), the most well-known examples of cannabinoids—a group of compounds produced by the cannabis plant. But it is also interesting to note the amount of other cannabinoids that have not been detected in any other plant. By some estimates, there are more than 100 cannabinoids found exclusively in the cannabis plant.

  • Riccardo Padovani: My year on HackerOne

    Last year, totally by chance, I found a security issue over Facebook - I reported it, and it was fixed quite fast. In 2018, I also found a security issue over Gitlab, so I signed up to HackerOne, and reported it as well. That first experience with Gitlab was far from ideal, but after that first report I’ve started reporting more, and Gitlab has improved its program a lot.

Another Chinese computer operating system: Will the UOS succeed?

Filed under
GNU
Linux

The Chinese just won't stop trying to build their own Windows equivalents and UOS is their new product.

Short for "Unified Operating System," the UOS is a joint effort by state-owned companies like China Electronics Corporation (CEC), and a former Windows customization group Deepin.

The OS looks largely like the Deepin OS, a system created in 2004 after the group created a Linux distribution.

[...]

And the software is rich. In addition to the innumerable Linux open-source software, the Deepin team also made their own text editor, video/audio player, terminal, voice recorder and more. Though many features are almost identical to similar apps, Deepin believes their version is more user-friendly and they are willing to customize the software based on users' feedback.

  • Sensitive information detection using the NVIDIA Morpheus AI framework

    The growth of cloud-native applications has driven an explosion of east-west network traffic within a datacenter where applications can create hundreds of thousands of network connections among virtual machines and containers. As a consequence, the ability to track, monitor, and secure a datacenter in a timely manner has risen above that of any individual or team, thus requiring the help of AI and machine learning (AI/ML) to enable ITOps, infrastructure security, and DevSecOps teams to manage the complexity of modern cloud-native applications and the underlying platforms. Red Hat and NVIDIA have been working together to bring the security analytics capabilities of the NVIDIA Morpheus AI application framework to Red Hat infrastructure platforms for cybersecurity developers.

  • How Podman runs on Macs and other container FAQs | Enable Sysadmin

    As the Podman machine function becomes more used—particularly on Macs—there have been many questions about how this all works. Some of what is tossed around on the internet is pure speculation, so this article aims to eliminate any speculation. Many people do not realize that containers are really Linux. As such, Linux containers cannot run natively on macOS. Therefore, the containers must run in a Linux virtual machine (VM), and a Podman client interacts with that VM. This is in line with all solutions for running containers on macOS.
