A practical walkthrough of TypeScript 6.0, the last release on the JavaScript codebase. The breaking default changes worth knowing before you upgrade, the smaller additions actually worth turning on, and what the Go-native 7.0 rewrite means for real build times.
A look at the vault structure, daily note template, and folder layout I use in Obsidian. The plain-file foundation that the /stream system writes everything into.
How I keep API keys, VPN credentials, and database passwords out of plaintext .env files using op environment. Two patterns, one for docker-compose, one for the small CLIs I run inside Claude.
A practical tour of how color reaches your terminal. SGR escape sequences, the 16-color palette, the bright vs bold confusion, 256 and truecolor extensions, the env var dance for detection, and why every CLI tool you use ends up speaking the same 16-slot alphabet.
How I wrote two bash CLIs to pull data from the Oura Ring and Fitbit Web APIs, wired them into my /stream planning system through 1Password and parallel data gathering, and why a readiness score of 58 changes what Claude puts on my task list.
