    ZFS On Linux 0.8.3 has the same kernel support of Linux 2.6.32 to Linux 5.4 as the previous ZoL release, but new are a ton of fixes. There are fixes from ZTS issues to various code issues that turned up from cppcheck, various encryption handling improvements, typo fixes, and over one hundred other changes in total for this point release in the ZFS On Linux 0.8 series.

  • Two Decades Late: Mainline Linux Kernel Getting Keyboard / Mouse Driver For SGI Octane

    The MIPS-based SGI Octane IRIX workstations were first introduced in the late 90's while recently there has been a resurgence in the work on getting these vintage PCs running off a mainline Linux kernel.

    For Linux 5.5 is initial mainline support for the SGI Octane systems two decades after they launched. We've also been seeing other driver work come about now that the Octane support is in place.

  • Linux 5.6 To Bring FQ-PIE Packet Scheduler To Help Fight Bufferbloat

    In addition to WireGuard being part of "net-next" as the networking subsystem material targeting the upcoming Linux 5.6 cycle, there is another big last minute addition to the networking space: the Flow Queue PIE packet scheduler has been merged.

    The Flow Queue PIE (FQ-PIE) network packet scheduler is another attempt at fighting bufferbloat. FQ-PIE is an improved packet scheduler over the existing PIE scheduling code. "It is an enhancement over the PIE algorithm. It integrates the PIE aqm with a deficit round robin scheme. FQ-PIE is implemented over the latest version of PIE which uses timestamps to calculate queue delay with an additional option of using average dequeue rate to calculate the queue delay."

  • Linux 5.5 Ready To Shine With Navi Overclocking, Raspberry Pi 4 Support, Wake-On-Voice

    Everything is aligning that the Linux 5.5 kernel is likely to be released this coming Sunday rather than being pushed off for another week of testing.

    As it's been two months since the Linux 5.5 merge window and already we've been quite busy talking about material on deck for Linux 5.6, here is a look back at some of the new features and changes of Linux 5.5...

Red Hat: Systemd, PulseAudio, Survey and OpenStack

  • Where I Stand on Systemd

    Once I turn to design considerations and technological benefits, however, I quickly bog down. The Unix philosophy of one utility to do one thing very well sounds admirable in theory, and perhaps on the administrative level it works well. Yet, I have heard few if any complaints that large apps like SE Linux or AppArmor violate the Unix philosophy, and on the desktop, apps like LibreOffice or Krita are clear violators. Could it be that some projects require a different approach to be effective? As a user, my initial tendency is to applaude Init Freedom’s rejection of “this one-size-fits-all vision” that led to the general acceptance of systemd in the major distributions. Yet as I think further, I wonder how practical supporting multiple init systems might be. In the recent Debian general resolution on systemd, both sides maintained that expecting maintainers to support multiple init systems would seriously add to the task of keeping packages current. The Devuan project itself appears to illustrate the difficulty, since it still uses Debian 9 as its basis and so far has been unable to add multiple init support itself. When finding maintainers is a constant problem for many distros, perhaps a limit on the number of supported init systems is sheer practicality.

  • PulseAudio 14 Is Releasing Soon With Better USB Gaming Headset Support

    In addition to PipeWire 0.3 having shipped last week, also making it out a few days prior was a development snapshot in the road to PulseAudio 14.0. PulseAudio 13.99.1 was released as a development snapshot in the road to the imminent PulseAudio 14.0. In the 6+ months since PulseAudio 13, developers have been working on various audio sink changes, automatic switching to HDMI audio is now disabled by default, flat volumes are also disabled by default, there is better support for USB gaming headsets, PulseAudio honoring Xauthority arguments for X11 modules, a workaround for GNOME Sound Settings behavior, and various other changes.

  • Enterprise open source software is growing within innovative companies

    Red Hat has been at the forefront of the global open source discussion, fighting for software freedom in the U.S Supreme Court, and offering free tech products for cloud infrastructure, automation, AI, and much more. After conducting research and interviewing IT leaders from around the world, Red Hat released a report examining the state of enterprise open source in 2020. 950 IT leaders, unaware that Red Hat was the research sponsor, were surveyed about their practices and opinions on enterprise open source software. [...] The benefits of using open source software seem obvious, namely that they are, of course, freely available. However, its lack of a price tag isn’t the main thing that IT leaders love. According to the survey, respondents believe that higher-quality software is the number one benefit of enterprise open source. FOSS software is often better than proprietary options, with better security, cloud-native technologies, and cutting edge solutions.

  • Red Hat OpenStack Platform 16 Delivers Long-Term Support

As of the Red Hat OpenStack Platform 16 release, there will now only be long-term support releases.
