  • Latest patches show Rust for Linux project making great strides towards the kernel [Ed: Linux is besieged by monopolies]

    Ojeda also mentioned that Microsoft's Linux Systems Group is contributing and hopes to submit "select Hyper-V drivers written in Rust." Arm is promising assistance with Rust for Linux on ARM-based systems. IBM has contributed Rust kernel support for its PowerPC processor.

  • ASUS Laptop dGPU Toggling, eGPU Handling, Panel Overdrive Patches For Linux - Phoronix

    A set of Linux kernel patches to the asus-wmi driver are pending that improve the support for newer ASUS gaming laptops.

    The ASUS WMI driver patches sent out today by independent developer Luke jones wire up support for panel overdrive, dGPU disabling/toggling, and eGPU enabling for relevant newer ASUS laptops.

    The panel overdrive support is for select ASUS laptops that allow driving the LCD panel slightly faster in order to eliminate/reduce ghosting artifacts.

  • [Old] Torvalds hopes future Linux 5.13 release candidates will ‘start shrinking’

    Linux creator Linus Torvalds has expressed mild concern over the size of kernel 5.13 following its fifth release candidate.

    “Hmm,” Torvalds opened his latest State of the Kernel post. “Things haven’t really started to calm down very much yet, but rc5 seems to be fairly average in size. I’m hoping things will start shrinking now.”

    In April, Torvalds warned that 5.13 would likely be “making up” for the smaller release of 5.12 – a position he maintained following the release of the first release candidate.

Rust in the Linux kernel

  • Rust in the Linux kernel: good enough for driver development
  • Google's Linux challenger just got a hugely useful update

    The Rust for Linux initiative made significant progress after lead developer Miguel Ojeda sent in a revised set of patches to shore up support for adding Rust as a secondary programming language within the Linux kernel.

    Ojeda has been spearheading the initiative and his work is now sponsored by Google, who along with a large section of developers, are pushing for Rust to be used in the Linux kernel, especially in areas where security and memory safety are of utmost importance.

    The set of 17 patches lay the groundwork for the initiative with important components such as a beta Rust compiler, an example driver, and more.

  • Programming languages: Rust in the Linux kernel takes another step forwards

    The Google-backed project to make Rust a second programming language in Linux kernel development after C just took it's next big step.

    Key to the project is Spain-based developer Miguel Ojeda, who's been leading the charge to bring Mozilla-hatched systems programming language Rust to the Linux kernel.

  • SD Times news digest: TypeScript 4.4 beta, Rust support improvements in Linux kernel, Sauce Labs acquires Backtrace

    The Linux kernel received several major improvements to overall Rust support including removed panicking allocations, added support for the beta compiler as well as testing.

    The goal with the improvements is to have everything the kernel needs in the upstream ‘alloc’ and to drop it from the kernel tree. ‘Alloc’ is now compiled with panicking allocation methods disabled, so that they cannot be used within the kernel by mistake.

    As for compiler support, Linux is now using the 1.54-beta1 version as its reference compiler. At the end of this month, `rustc` 1.54 will be released, and the kernel will move to that version as the new reference.

    Additional details on all of the support improvements are available here.

Cycles X Merged Into Blender 3.0 With NVIDIA CUDA/OptiX Support, AMD HIP Pending

Cycles X as a modernizing of Blender's Cycles rendering engine has now landed in the latest development code for Blender 3.0. Cycles X brings big performance improvements but does eliminate OpenCL support in the process. Cycles X was one of the reasons for the delay in the Blender 3.0 release to allow time for this Cycles overhaul to land. As of yesterday, the Cycles-X branch was merged into the Blender 3.0 code-base as a major renderer update. Read more

Oracle's Next-Generation GNU Profiler "gprofng" Is Looking Great For Developers

Oracle engineers have been working on "gprofng" as a next-generation GNU Profiler that can analyze production binaries. Oracle talked up Gprofng today during the GNU Tools Track as part of Linux Plumbers Conference 2021. Gprofng stems from Oracle Developer Studio's Performance Analyzer and this new tool currently supports profiling C, C++, Java, and Scala code. Unlike the original gprof, gprofng is able to profile production binaries that do not need to be built with any special options or still have the source code available. Unmodified executable can be easily analyzed and a wealth of information provided. Read more

Software: Host Identity Based Authorization, Baby Buddy, and Foreman

  • Google publishes HIBA, an OpenSSH add-on for certificate-based authorization

    Google has published the source code for the project HIBA (Host Identity Based Authorization) , which proposes the implementation of an additional authorization mechanism for organizing user access via SSH in relation to hosts (checking whether or not access to a particular resource is allowed when authenticating using public keys). Integration with OpenSSH is provided by specifying the HIBA handler in the AuthorizedPrincipalsCommand directive in / etc / ssh / sshd_config. The project code is written in C and is distributed under the BSD license. HIBA uses standard authentication mechanisms based on OpenSSH certificates for flexible and centralized management of user authorization in relation to hosts, but does not require periodic changes to authorized_keys and authorized_users files on the side of the hosts to which it is connected. Instead of storing a list of valid public keys and access conditions in authorized_ files (keys | users), HIBA integrates the host binding information directly into the certificates themselves. In particular, extensions are proposed for host certificates and user certificates, which store host parameters and conditions for granting user access. Host-side verification is initiated by calling the hiba-chk handler specified in the AuthorizedPrincipalsCommand directive. This handler decodes the extensions integrated into the certificates and, based on them, makes a decision to grant or block access. Access rules are defined centrally at the certification authority (CA) level and integrated into certificates at the stage of their generation.

  • Baby Buddy: an Open-source Free newborn digital assistant

    Baby Buddy is a free open-source web-based solution for new parents to help them log, monitor and track their parenting activities. [...] Baby Buddy is a built by Christopher Charbonneau Wells who has released many interesting projects. The project built with Django (Python), and uses several development libraries for front-end development. Note that it is under continues development so expect more features in the near future.

  • Foreman 3.0 crams Puppet ENC into plugin, takes steps towards better UX • DEVCLASS

    Server lifecycle management project Foreman recently saw its third major release, which provides users with a couple of changes that should align the tool somewhat closer with their actual workflow. Amongst the main features of version 3.0 is a still experimental reimagining of the UI’s host detail page. Instead of admins having to click through tabs to get more information about a given host, those details are now readily available on the main host page, along with a central indicator of its status and the usual audit and job data. Users interested in this kind of display can activate the new host page by setting the “Show Experimental Labs” setting in the generic administration settings to yes and selecting “New Details Page” from the host’s dropdown action button. A couple of things — such as the edit button and the menu next to it — still don’t work as intended, and having the option to customise the page would make the new UI even more useful, but it surely is a good first step towards making the page more user-friendly. The Foreman team also promised to get rid of the malfunctions mentioned in version 3.0.1 and asked for additional feedback on the new details page, so users have a good chance of getting their submitted issues fixed quickly if they start testing soon.
