TIL that many API keys today are prefixed "sk" because Stripe used to have them unprefixed and many people leaked them in logs, so a prefix "pk_" for public key and "sk_" for private helped with filtering. Somehow I always took that for granted and not as a fact of software evolution

Made my first coding agent. Not sure if I have better understanding of them now or the opposite - https://zserge.com/posts/socreates/ #llm #deepseek #coding #golang

Finished a small educational project: https://zserge.com/posts/pennybase - a toy clone of Firebase/Supabase/Pocketbase. In 700 lines of Go with zero dependencies it has dynamic record schemas, reasonably fast "document store" using CSV files, orthogonal REST APIs + realtime watch over SSE, authNZ with simple RBAC, pluggable hooks.
Enough to build a real-time chat app or a management system. Works well with HTMX and Go templates.
Not for serious use, of course! #golang #backend #baas #firebase #rest #csv
