GitNexus by Akon Labs is an open-source kernel designed for coding agents, providing a foundational tool for AI-driven software development.
The article describes the optimization of AMD MI350X GPUs for running the Qwen3.6-35B-A3B LLM, achieving high output token throughput and open-sourcing the kernel to improve performance.
Linux 7.2 has been released with significant improvements including cache-aware scheduling, power management for Raspberry Pi GPUs, and various performance enhancements.
egos-2000 is a teaching operating system project that implements core operating system components in just 2000 lines of code. It features a clear three-layer architecture, supports the RISC-V platform, and comes with a textbook providing 9 course projects for convenient learning and practice.
The post argues that Linux is a good kernel, but no effective operating system has been built on it yet.
A minimal kernel designed to run a NES emulator without any operating system, with additional programs like Mandelbrot fractal visualization.
A tweet shares a free book called 539kernel that teaches building an entire operating system from the x86 boot sector at address 0x7C00, progressing from the first instruction to a working kernel.
Linus Torvalds describes Linux Kernel 7.2 as "huge" because AI tools are now reviewing kernel code faster than humans, despite his earlier criticism of low-quality AI-generated patches and bug reports. He accepts this as the new normal, noting Linux is not an anti-AI project.
ATFlash introduces a per-RoPE-wavelength distance window that prunes query-key inner-product terms proportional to each frequency pair's wavelength, cutting 37-48% of attention compute with minimal quality loss and up to 1.31x speedups on long-context LLM inference.
Cursor is open-sourcing Mixture-of-Kittens (MoK), a production MoE training megakernel for NVL72s that fuses communication and computation, delivering a 1.41x end-to-end training throughput improvement for their Composer model.
A new AMD Linux kernel patch improves low-end gaming performance on Steam Deck by monitoring core workloads and temporarily setting busy cores to performance mode, resulting in up to 31.8% improvement in 1% low FPS in Civilization VI.
The article discusses the integration of AI tools like LLMs in Linux kernel development, highlighting Linus Torvalds' support for AI-assisted code and the controversy around the new Sashiko code review tool, while critiquing Torvalds' dismissal of ethical concerns.
This article demonstrates how to profile eBPF code performance by creating a simple C test harness that measures file open latency, enabling developers to compare overhead before and after attaching eBPF hooks.
Apple's MIE exploitation challenge details two vulnerabilities in WebDAV and SMBClient that allow kernel exploitation, with a call for community solutions before Black Hat USA presentation.
An analysis of Linus Torvalds' unique role as a leader who stopped writing code early to focus on coordination and direction of the Linux kernel project, contrasting with other maintainers.
