Best practices for writing a design doc based on my experience working as a developer at Google and Microsoft.

Every language pitches async/await as synchronous-looking code, and the same two keywords appear everywhere. But behind the shared syntax hide nine independent design decisions, and no two of seven modern runtimes agree on what even the simplest async programs should do! In this paper we map the design space of async/await so you can find out where your language stands.

After my last post about GenStage, this one's a visual explainer of how Elixir's Broadway works and all the knobs you can use to tune pipelines.

Learn how to evolve message schemas in distributed systems, handle backward and forward compatibility, and safely roll out producer and consumer changes.

You can register a process name globally in Elixir and OTP will ensure it's unique, but there are some surprising edge cases. This shows a pattern for safely defining cluster singletons.

An educational side project: a local-first expense tracker built with Automerge CRDTs in Elixir, Phoenix, and Tauri, plus how I surface sync conflicts.

`foxing` (formerly xfs-mirror) aspires to be a production-grade, eBPF-powered replication engine for Linux filesystems (XFS, Btrfs, F2FS, Ext4). It captures filesystem events in the kernel and replays them asynchronously on a target directory, providing near real-time mirroring with robust consis...

TRON (The Real-time Operating system Nucleus) is an open architecture real-time operating system kernel design. The project was started by Ken Sakamura of the University of Tokyo in 1984. The project's goal is to create an ideal computer architecture and network, to provide for all of society's needs...

I have been probably obsessed with two things in the last few years: Nix as a tool to explore innovative ideas that require the capability to rebuild the world and replacing ELF with SQLite as an executable format. You might have noticed that these two ideas are well suited to each other.
