FreeBSD
Last week I was in Taipei, Taiwan, for the FreeBSD Developer Summit and AsiaBSDCon 2026. Here's how it went. Devsummit The Developer Summit ran for two days, 10 AM to 5 PM each day. Most sessions were short presentations covering topics like FreeBSD on WSL 2 and Ansible

Jujutsu is a version control system that pairs Git's proven storage backend with a rethought approach to code management workflows. I currently use it across all of my repositories—with the sole exception of freebsd-src, which relies on a prepare-commit-msg hook that Jujutsu does not yet support. There

FreeBSD offers several approaches to kernel debugging: DDB, live kernel debugging, and core dump analysis. DDB is an interactive debugger built directly into the FreeBSD kernel, with syntax inspired by GDB — making it immediately familiar to most developers. Live debugging leverages FreeBSD's GDB stub (defined under sys/gdb)

There are many CPU schedulers out there — ULE, 4BSD, CFS, and EEVDF, to name a few — but none of them are perfect. Every scheduler has areas where it excels and areas where it falls short. That's acceptable when the shortcomings stem from fundamental design trade-offs (e.g., the
Microarchitecture
The Rise and Fall of SPARC Once upon a time, there was a company called Sun Microsystems, founded by legendary computer engineers like Bill Joy. Sun shipped products across a remarkable range of domains: programming languages (Java), databases (MySQL, though it originated at a Swedish company), operating systems (SunOS and

I recently started a 14-day trial on Ghost and migrated my articles from Substack. In this post, I'll walk through why I originally chose Substack, what drove me to explore Ghost, and how the two platforms compare after migration. Why I Originally Chose Substack When I first decided
