Raymond Chen explains how Windows on AArch64 implements function hot-patching more simply than on x86, using a 12-byte patch space and a three-instruction trampoline via the xip0 scratch register, noting that pointer authentication (pacibsp) usually guards the function entry.

75 raylib examples implemented in Jolt, a native Clojure on Chez Scheme, demonstrating efficient FFI bindings for raylib's C API without a JVM.

GNU Hurd's 2026 Q2 quarterly report highlights progress on 9pfs write support, AArch64 kernel patches, POSIX msync validation, and various bug fixes.

Kakehashi is an experimental userspace that translates macOS ARM64 binaries to run on Linux aarch64 by loading Mach-O files, mapping a freestanding libSystem, and translating BSD syscalls. It currently supports running tools like 7-Zip and curl, including multithreaded operations, on Linux ARM via Docker or UTM.

Marcin Juszkiewicz concludes his 11-month experiment using an Ampere Altra AArch64 system as a desktop, citing ongoing PCIe issues that required custom kernel builds and limiting its viability as a daily driver.

An educational article that explains how ARM64 (AArch64) instructions are encoded in 32-bit fixed-length words, debunking common misconceptions and providing hands-on decoding examples using ADD immediate on Apple Silicon.

A developer shares his experience using an 80-core ARM desktop, noting that while multi-core builds are fast, single-thread performance and latency issues cause problems for everyday tasks like web browsing and audio playback.

PyTorch 2.11.0 now publishes CUDA-enabled aarch64 wheels to PyPI, fixing a long-standing installation issue for vLLM on NVIDIA Grace Hopper and Grace Blackwell systems, eliminating the need for custom index URLs and preventing silent CPU wheel replacements.

The article introduces 'ymawky', a minimal HTTP web server written entirely in aarch64 assembly for macOS, using raw syscalls without libc wrappers to explore low-level system mechanics.
