This article introduces the binfmt_misc feature introduced in the Linux kernel in 1997. It allows registering rules to hand off binary execution to a specified interpreter. Today, combined with Rosetta on Apple Silicon Macs, it enables efficient x86 container operation, achieving performance close to 70-90% of native.
WSL 2 is receiving a performance improvement where each virtio device gets its own dedicated DMA (SWIOTLB) pool, eliminating contention on the virtiofs path for cross-OS file access between Windows and Linux. This change, merged in May 2026, is the latest in a series of incremental improvements to Windows/Linux file I/O performance in WSL 2.
A blog post announcing CodeView, a virtualization-first React component for efficiently rendering large code diffs, part of the Diffs library released six months ago.
Neptune brings Direct3D virtualization to QEMU, enabling Windows GPU acceleration in virtual machines, developed with significant assistance from AI agents like Claude.
Fenng believes that if Microsoft provides every GitHub account with a VM option, allowing code to run in the cloud, developers can debug from any device, which would impact the Mac mini.
User @binsquares reports that GPU acceleration on smolvm achieves nearly 90% of host performance when running llama.cpp via the Vulkan backend.
Joanna Rutkowska announces the relaunch of her blog after a seven-year hiatus, reflecting on her past work with Qubes OS and her evolving perspective on rationality versus humanism.
Apple has released an open-source tool called 'container' that creates and runs Linux containers as lightweight VMs on Mac with Apple silicon, supporting OCI-compatible images.
