CEO Zach Lloyd on the Benefits of Open Sourcing Warp

How Warp built an agent-first open source contribution workflow that actually works. 56K GitHub stars, 500 contributors, and one clear signal: Agents and humans build better open source software together. The post CEO Zach Lloyd on the Benefits of Open Sourcing Warp appeared first on FOSS Force.

[$] Swap tables, flash-friendly swap, swap_ops, and more

The kernel's swap subsystem is charged with managing anonymous pages in secondary storage when those pages are (hopefully) not being used and the memory they occupy is needed elsewhere. This long-unloved subsystem has seen a resurgence of developer interest in recent times, so it is not surprising that it was the topic of three separate sessions in the memory-management track at the 2026 Linux Storage, Filesystem, Memory Management, and BPF Summit. Two of those sessions were concerned with improving the performance and maintainability of the swap code, while one (shared with the storage track) was about how swapping could be friendlier to solid-state storage devices.

Linux 6.6 LTS To Linux 7.1 Bechmarks: Performance Up 13% On AMD Threadripper Over Three Years

The Linux 7.1 kernel performance has been looking quite good on the various Intel/AMD systems I have tested over the past three weeks. Linux 7.1 does bring some solid improvements over Linux 7.0 prior in different workloads and haven't encountered any worrisome regressions compared to the current Linux 7.0 stable kernel. For those wondering the longer-term picture, here are benchmarks of Linux 7.1 Git compared to recent Linux LTS kernel series going back to 2023 for providing a picture at how the upstream Linux kernel has netted 13% faster performance (geo mean) on the same hardware in less than three years.

Canonical share Ubuntu 26.04 concept build for CIX P1 devices

Canonical has shared a new Ubuntu Concept image for the CIX P1, an Armv9 SoC powering single-board computers like the Radxa Orion O6 and Orange Pi 6 Plus. The image is based on Ubuntu 26.04 LTS and ships with a Linux 7.0 kernel from CIX’s open-source GitHub tree using only open-source drivers. A set of patches sits on top of the mainline kernel, but the goal for them to be upstreamed too. Canonical is also targeting ACPI rather than Device Tree in the CIX P1 concept image. This is the same approach taken with its Snapdragon X Elite builds and […]
