Simon Willison's Newsletter

Simon Willison's newsletter shares his notes and experiments across Python, SQLite, data journalism tooling, and increasingly the practical side of working with large language models. Willison is a well-known open source contributor (co-creator of Django) and writes with the specificity of someone building and testing things himself rather than summarizing others' work.

Posts often walk through a technique or tool in enough detail to be genuinely useful, from SQLite extensions to prompt-engineering tricks for new AI models. It's a good match for developers who want hands-on, technically credible commentary on fast-moving tools, written by someone testing them in public as they go.
