Saturday I cleaned a PS5. By Sunday evening a 4 GB Raspberry Pi was running my DNS, a password vault and offsite backups, and the lessons had spun off into Lares, a small public stack built around what happens when things fail. On Monday it bit back.
A falsification experiment with a written kill list and a negative result. Delta has a purpose-built idempotent commit; iceberg-rust rebases a transaction onto a base the caller never checked, so an external writer cannot make a commit conditional. The green concurrency test was a false pass — 0 of 40 rounds ever raced — and only a failpoint showed the duplicate.
I started with Milan in Championship Manager 03/04, went through an almost perfect auction and a season shaped by injuries, then built Fantabuddy on holiday: a system that turns player lists, history and APIs into an auditable auction report.
I opened a bug report against dbt and found a codebase nobody had told me about: 77 Rust crates where the Python used to be. This is what the rewrite is actually for, why the marketing undersells it, and what I broke loose while poking at it — two fixes, both for bugs that never printed an error.
I had never publicly written about Nephtys, and the first thing I have to report about it on real hardware is a null result: the memory advantage reproduced on a Raspberry Pi 5, the energy advantage never existed.
Brain is a Git-backed Markdown knowledge base. Brain UI is the Rust/Leptos control plane on top of it. This is the system, the connection between the two halves, a real config-driven taxonomy, and the honest reasons I’m putting the core in the open.
A deep dive into Mosaico, the robotics data platform written in Rust: client-server architecture, semantic ontologies, data-oriented debugging, my journey within it, and the integration with Data Contract Engine.
