  • Kubernetes Blog ☛ Kubernetes v1.37: Metrics API graduates to stable

    Kubernetes v1.37 promotes the metrics.k8s.io API to stable (v1). This API provides CPU and memory usage for nodes and Pods, and is the API behind commands such as kubectl top and resource-metrics-based autoscaling.

    For cluster operators and application developers, this graduation means that the API now has the stability guarantees associated with a Kubernetes stable API. The v1 API has the same resource types and fields as v1beta1; this is an API-version graduation, not a change to the metrics that are collected or returned.

• Graphics Stack

  • Timur Kristóf ☛ The GCN outcast - Radeon HD 7870 XT

    AMD is known to be Linux friendly and has had an open source driver stack for their GPUs for more than a decade. However, there was one GPU that has always been an outcast on Linux because it has never worked: the Radeon HD 7870 XT. This post is about how I fixed that so that Linux gamers can enjoy this GPU being fully functional now.

    The Radeon HD 7870 XT is built on the GCN 1 architecture (also known as Southern Islands or SI, or GFX6). It has a chip called “Tahiti LE” which is a variant of the Tahiti chip that was quite high-end by 2012 standards. Tahiti and other GCN 1 chips have been supported on Linux for more than a decade, first by the radeon kernel driver and more recently by the amdgpu kernel driver.

    We have every reason to assume that the 7870 XT should “just work”, so why doesn’t it?

    • Tickets in Transitous

      As you might already know, Transitous is a project that runs a public transport routing service that aims to work world-wide.

      To make Transitous results more useful, there needs to be a simple way to book the individual sections of a multi-modal route.

      It is important to mention that Transitous can not legally sell tickets itself, and there are no plans to change that, so booking in this case means directing users to a ticket shop that can sell tickets for the route.

• Distributions and Operating Systems

  • HaikuOS ☛ R1/beta6 – Release Notes

    The sixth beta for Haiku R1 comes just about a week after Haiku’s 25th anniversary. We’ve come a long way since the project began a quarter-century ago in 2001. Thank you to everyone who’s supported us thus far, and here’s to another 25 years of Haiku!

    This release contains almost two years of the development team’s hard work to improve Haiku’s features and overall stability, and to make more software available for use. Over 530 bugs and enhancement tickets have been resolved for this release.

  • BSD

    • MWL ☛ 126: Low Distress Tolerance

      I finished the OpenZFS Mastery chapter on volumes earlier this week. Zvols support sparse volumes, also known as thin provisioning or overcommitting storage. A sparse volume is a volume that reserves less space than the volume actually needs. Sparse volumes permit allocating more space than the pool has available.
