  Hi HN, I've been building Chronoid, a native macOS time tracker. It runs in the menu bar and automatically logs apps, windows, and file activity using macOS accessibility APIs. Everything is stored locally, no sync or cloud service. At first I tried using DuckDB as the storage engine. It looked promising for analytics, but after ~2 weeks I realized it was overkill for my needs—extra dependencies, trickier integration, and not much real benefit at the scale of a single-user app. I switched to SQLite, and it turned out to be the simpler, more reliable choice. The codebase got smaller and the…

  LLMs can generate valid JSON 100% of the time▲854

  Outlines is a Python library that focuses on text generation with large language models. Brandon and I are not LLM experts and started the project a few months ago because we wanted to understand better how the generation process works. Our original background is probabilistic, relational and symbolic programming. Recently we came up with a fast way to generate text that matches a regex (https://blog.normalcomputing.ai/posts/2023-07-27-regex-guide...). The basic idea is simple: regular expressions have an equivalent Deterministic-Finite Automaton (DFA) representation. We…
