If you’re on one of the cheaper Anthropic plans like me, it’s a pretty common scenario when you’re deep into Claude coding an idea, to hit a daily or weekly quota limit. If you want to keep going, you can connect to a local open source model instead of Anthropic. To monitor your current quota, type: /usage

Contracts in Nix
The Nix language lacks a good type system . There are already several configuration languages that provide static and even gradual typing (see, e.g., Cue , Dhall , or Nickel ), but none offer the ability to easily annotate legacy Nix code with types.

I have come to appreciate coding agents to be valuable tools for working with computer program code in any capacity, such as learning about any program’s architecture, diagnosing bugs or developing proofs of concept. Depending on the use-case, reviewing each command the agent wants to run can get tedious and…
