Not so locked in any more

This Mitchell Hashimoto quote about Bun migrating from Zig to Rust reminded me of a similar conversation I had at a conference last week. I was talking to someone who worked for a medium sized technology company with a pair of legacy/legendary iPhone and Android apps. They told me they had just completed a coding-agent driven rewrite of both apps to React Native. I asked why they chose that, given that coding agents presumably drive down the cost of maintaining separate iPhone and Android apps.…

[...] On the interesting side is how fungible programming languages are nowadays. Programming languages used to be LOCK IN, and they're increasingly not so.

Here's the production configuration I'm using on that site for the new plugin: datasette-ip-rate-limit: header: Fly-Client-IP max_keys: 10000 exempt_paths: - "/static/*" - "/-/turnstile*" rules: - name: demo-databases paths: -…

Welcome to the Datasette blog

Welcome to the Datasette blog

Welcome to the Datasette blog We have a bunch of neat Datasette announcements in the pipeline so we decided it was time the project grew an official blog. I built this using OpenAI Codex desktop, which turns out to have the Markdown session transcript export feature I've always wanted. Here's the session that built the blog. See also issue 179.
