  • Codeplay Launches Open-Source 'SYCL Academy' To Learn This Increasingly Popular Standard

    While SYCL has been around for five years as a Khronos standard providing a single-source C++ programming model for exploiting OpenCL, it has yet to reach its prime but demand for it is picking up with Intel working to upstream their SYCL back-end in LLVM, SYCL becoming part of their programming model with oneAPI and Xe Graphics, and other vendors also jumping on the SYCL bandwagon. Codeplay has now provided an open-source SYCL learning code for those interested in this higher-level alternative to straight OpenCL programming.

  • Open-Source Build and Test Tool Bazel Reaches 1.0

    Derived from Google's internal build tool Blaze, Bazel is a build and test tool that offers a human-readable definition language and is particularly aimed at large, multi-language, multi-repositories projects. Originally open-sourced in 2015, Bazel has now reached 1.0.

    One of the major implications of reaching version 1.0 for Bazel is the promise of greater stability and backward-compatibility guarantees. This has been a historical pain point for Bazel users, who often found themselves in the situation of having to rewrite part of their build rules due to frequent breaking changes in Bazel or its ecosystem. Accordingly, the Bazel team has committed to following semantic versioning for future Bazel releases, meaning only major versions will be allowed to include breaking changes. Furthermore, the team committed to maintaining a minimum stability window of three months between major versions.

  • DevOps Deeper Dive: DevOps Accelerates Open Source Innovation Pace

    That rate of innovation has increased dramatically in the last few years. However, much of that innovation would not have been possible if large swaths of the open source community hadn’t been able to employ best DevOps practices to collaborate, said CloudBees CEO Sacha Labourey.

    [...]

    None of this shift has been lost on IT vendors. As the demand for proprietary code slackened, many found it profitable to offer support services for open source software. The more there is to consume, the more the support services contracts grew. Now every vendor from IBM to small IT services providers such as Fairwinds has launched open source projects that help drive demand for IT services expertise.

    “There’s pain around integrating a lot of disparate open source projects,” said Robert Brennan, director of open source software for Fairwinds. “Organizations may be getting software for free, but there’s usually not a lot of help around.”

    Now almost every IT vendor in the world is making software engineers available to work on open source projects. All that talent focused on open source projects has led to the development of new platforms such as Jenkins, GitHub, Kubernetes and, more recently, a raft of smaller projects. With the rise of containers and cloud-native applications, open source software projects are entering another era that will see many of those same software engineers leveraging DevOps practices more broadly to drive even more innovative projects at increasingly faster rates.

  • Find your next developer from open source communities

    Meanwhile, demand for data scientists is rising as companies seek AI-based solutions to stay competitive. Demand is reflected in salary offers. Companies competing to hire and retain data experts are offering on average more than US$100,000, making it one of the most highly paid professions in the States.

    For companies lacking the budget to hire or train in-house staff to fill the role, they may find themselves struggling with maintaining technological infrastructure or moving forward with plans for digitization.

    Therefore, open source learning and further development of communities could be the solution to this gap.

    An IBM grant to support open source communities such as Girls Who Code, a non-profit organization offering coding lessons for women in the US, is a step forward to filling in a shortage of software developers.

  • Two More X.Org Server Security Advisories Issued - Possible Privilege Escalation - Phoronix

    Trend Micro's Zero Day Initiative has uncovered two more security issues with the aging X.Org Server that as we roll into 2021 is still powering most of the Linux desktops. The security researchers found multiple input validation failures with the X.Org Server's XKB keyboard extension. Insufficient checks on different checks could lead to out-of-bounds memory accesses or buffer overflows.

  • Intel Begins Preparing Linux Graphics Driver Support For Xe HP As "Gen12.5" - Phoronix

    Xe HP is Intel's discrete GPU aiming to compete against the latest-generation AMD and NVIDIA compute accelerators. Xe HP isn't scheduled to reach general availability until well into 2021 while now as they begin ramping up their sampling of Xe HP to potential customers, the Linux open-source driver support is preparing to roll-out. While Xe HP is about scaling up Intel Xe Graphics (Gen12), the Xe HP driver support is introducing it as a new "Gen12.5" target rather than just "Gen12" that is used by Tiger Lake / Rocket Lake / Xe LP.

  • NVIDIA Is Working On DMA-BUF Passing That Should Help Improve Their Wayland Support

    NVIDIA is working on allowing their proprietary driver to support passing buffers as DMA-BUF. In turn this should allow for better supporting their proprietary driver on Wayland compared to the EGLStreams mess. A Phoronix reader tipped us off to NVIDIA developer comments last month in response to a KDE EGLStreams bug. A bug report was opened regarding that restarting the compositing breaks the EGLStreams back-end for KDE's KWin.

  • Mesa Now 2~5x Faster For SPECViewPerf Following OpenGL Optimizations - Phoronix

    Well known open-source AMD Linux graphics driver developer Marek Olšák has just merged one of his largest set of optimizations in recent times: 2~5x faster performance for SPECViewPerf. SPECViewPerf is the common industry benchmark for measuring graphics performance for professional applications with benchmark viewsets from 3ds Max, CATIA, Maya, Solidworks, Siemens NX, and other programs. The performance when using Mesa drivers have been lagging but now thanks to common Mesa infrastructure improvements by Mesa, the performance is wildly improved.
