  • Klara ☛ Optimizing ZFS for High-Throughput Storage Workloads - Klara Systems

    Most people know ZFS as a stable, resilient, and durable file system that excels at large-scale storage and backup workloads. What few understand is that ZFS is also a highly performant file system when configured and tuned correctly.

    ZFS has many aspects that provide performance benefits. From the ARC, to prefetching, metadata devices, DirectIO, and many other capabilities, ZFS is able to provide performance optimizations that other filesystems do not offer.

• Graphics Stack

  • Collabora ☛ PanVK now uses AFBC by default

    AFBC support has been merged to PanVK and will be available in the Mesa 25.3 release! This new enablement reduces memory bandwidth and boosts performance.

    • Distro Watch ☛ Distribution Release: Omarchy 3.0.1

      David Heinemeier Hansson has announced the release of Omarchy 3.0, a significant upgrade to the project's Arch-based Linux distribution featuring the Hyprland tiling window manager and designed primarily for software developers. Unlike the previous releases, this one provides a much larger ISO image, suitable for offline installations. [...]

    • Red Hat ☛ A deep dive into Apache Kafka's KRaft protocol

      This guide breaks down the key concepts of Apache Kafka's KRaft protocol and dives into its implementation, based on Apache Kafka 4.1.0 (KRaft v1). If you're a developer or engineer looking to solidify your understanding of how KRaft works under the hood, this post is for you. A basic understanding of Kafka is assumed. If you're already familiar with the Raft algorithm, you can skip ahead a few sections.

  • Debian Family

    • LWN ☛ Jackson: tag2upload in the first month of forky

      Ian Jackson has published a blog post summarizing the tag2upload service's first month of handling uploads for the upcoming Debian 14 ("forky") release:

      We announced tag2upload's open beta in mid-July. That was in the middle of the the freeze for trixie, so usage was fairly light until the forky floodgates opened.

    • John Goerzen ☛ John Goerzen: Installing and Using Debian With My Decades-Old Genuine DEC vt510 Serial Terminal

      Six years ago, I was inspired to buy a DEC serial terminal. Since then, my collection has grown to include several DEC models, an I.C.B.M. 3151, a Wyse WY-55, a Televideo 990, and a few others.

      When you are running a terminal program on GNU/Linux or MacOS, what you are really running is a terminal emulator. In almost all cases, the terminal emulator is emulating one of the DEC terminals in the vt100 through vt520 line, which themselves use a command set based on an ANSI standard.

      In short, you spend all day using a program designed to pretend to be the exact kind of physical machine I’m using for this experiment!

  • Canonical/Ubuntu Family

    • Unicorn Media ☛ Multipass Makes Spinning Up Ubuntu Images as Simple as It Gets

      Multipass offers a quick way to create Ubuntu virtual machines with no extra hardware or complex setup needed.
