A developer has released an early preview of GEFS, a crash-safe copy-on-write file system originally written for 9front, now being ported to OpenBSD. The port is not production-ready and data loss is expected, but remaining issues are understood and the code is available for testing and development.
Matthew Macy was contracted to port WireGuard into FreeBSD's kernel for Netgate's routers, but his implementation contained numerous bugs and security issues that went largely unreviewed before being committed to FreeBSD 13.0. WireGuard founder Jason Donenfeld discovered the problems and, along with Kyle Evans and Matt Dunwoodie, replaced nearly all of Macy's code in an intensive week-long effort to fix critical issues before release.
wireguard-go is a Go implementation of WireGuard that creates VPN interfaces via command-line. It runs on Linux, macOS, Windows, FreeBSD, and OpenBSD with platform-specific limitations, and can be compiled from source using Go and Make.
A researcher demonstrates that zero-day vulnerability discovery is not exclusive to frontier AI models like Anthropic's Mythos, but can be achieved through orchestration frameworks like IronCurtain using commercial models (Opus, Sonnet) and open-weight models (GLM 5.1). The author replicated Anthropic's discovery of a 27-year-old OpenBSD TCP SACK vulnerability and autonomously found new zero-days, though at significant token costs ($30–$150 per investigation).
A user built a local LLM machine using a refurbished Miniforum UM790 Pro ($537) with AMD Ryzen 9 7940HS CPU, running OpenBSD and Linux with Ollama and Open Web UI. Performance achieves 5-20 tokens/second on CPU, comparable in quality to cloud services like Claude and duck.ai, demonstrating that expensive GPUs are unnecessary for practical offline LLM use.
MirageOS is a library operating system that constructs unikernels for secure, high-performance network applications. Developers write code on traditional OSes like Linux or macOS, then compile it into standalone unikernels that run on Xen, KVM, or lightweight hypervisors, deployable on public clouds or private infrastructure.
