Personal projects and writing by Billie.

Software, AI, self-hosting, experiments, and whatever else I’m interested in at the time.

The DJ tools I kept trying to build

How four years of DJ-library friction led from Python scripts to a Go desktop app and the AI-assisted Crate Lynx.

A compact experiment animates raw, PCA and grand-tour views of embeddings, then changes the basis without changing cosine neighbours.

What GPT-5.6 did across research, audits, a seven-repository migration and one animated pet during my first 48 hours with Codex.

The first GPT-5.6 LLM Choice batch was polished but shallow. A prompt built around ambition and depth produced much stronger artefacts.

A July 2026 field guide to free VPS, serverless, databases, product plumbing, developer tools, AI APIs, and GPU compute.

A local LLM Choice experiment showed how harnesses, repair loops, tools, and model strength changed coding-agent results.

A Discord argument about biological wheels became a deployed Cloudflare Pages simulation in about ten minutes.

A low-friction Linear idea ledger works for me because voice and agents made capture and retrieval cheap enough to happen.

Using autonomous coding-agent runs as a low-cost way to find ideas, learn unfamiliar topics, and seed later projects.

A small site graph made billiem.uk feel more like a growing personal object than a fast but flat static site.

A local LoRA experiment on Discord data became a lesson in data shape, routing, evaluation, and knowing when to stop.

A chair scraper turned a fragmented refurb search into a dashboard and alerts, saving more than £100 in a few days.
