In May 2026, the Bun team did something the software industry has been whispering about for years: they rewrote their entire runtime from Zig to Rust. Not over the course of a year with a dedicated team. In six days. Using AI agents. At nearly a million lines of code, Read more ›
Previously I installed immich on my home server on a VM, run by OpenBSD’s VMD. This was working great until one day the VM won’t boot ;-( The log file /var/log/daemon shows these two lines. The only vaguely relevant thread I can find suggests this is a new feature of linux attempting to use some feature which OpenBSD’s VMD doesn’t yet emulate. It also suggests a flag to pass to the linux kernel on boot to attempt to work around. After some frustration, I finally managed to get a system-rescue... Read more ›
About the project The FreeBSD Foundation has launched its AI-assisted Vulnerability Discovery Project with the key goal of reducing the number of exploitable vulnerabilities in the FreeBSD source code. The 6-month project is being funded by a grant from the Alpha Omega project. The funds will be used to engage FreeBSD Security Team members under Read more ›

OpenBSD's sppp(4) subsystem handles synchronous PPP links, the backbone of PPPoE connectivity. When a peer connects, the PPP handshake can require PAP (Password Authentication Protocol) credentials before the link reaches STATE_OPENED. The check that decides whether to accept or reject those credentials has been broken since it was first imported into the OpenBSD source tree in July 1999. Read more ›

FreeBSD Jails and Linux LXC both provide operating system-level virtualization, but their design philosophies differ significantly. This article explores how each approach handles isolation, security, observability, ZFS integration, and operational complexity to help infrastructure teams determine which model best fits their environment.

The opening post of a Low-Level Systems Design in Rust series, arguing that the biggest performance win is structural: replace a shared multi-producer cursor that serializes cores through cache-coherence traffic with one private single-writer SPSC ring per producer, converting quadratic writer contention into a cheap O(N) consumer sweep.

Earlier studies showed that Opus 4.6, GPT 5.4, Gemini 3.1-pro-preview, Deepseek R1-0528, and Qwen 3.6-plus were unable to find two of the vulnerabilities discussed in the Mythos blog post without extremely revealing hints. This study continues the previous experiments with 26 distinct Claude-4.6/4.7 and GPT-5.4/5.5 combinations and different context window sizes and reasoning efforts. It found that higher reasoning effort, and even later models, are not always better for triaging security res... Read more ›
Many people want to know, precisely, which pieces of text are valid Rust programs, and for those that are, what they do. This group includes compiler writers, language designers, researchers, unsafe code writers, safety-critical industry assessors, and of course any Rust developer trying to understand a piece of code.
