uv has 350k lines of Rust, and 73 "unsafe" calls. The Bun Rust port is already 681k lines of Rust, and has over 13,000 "unsafe" calls.



the future of software engineering seems uncontroversially prompting + code review. startups will skip the code review because they’re racing against time. larger/serious orgs will take code review very seriously. llms can do code review, but my guess is that because they have to search through large space, it will be as expensive to have say mythos review your code as it would be to have a senior dev. based on budget: $: prompting only $$: low grade llm review $$$: mid grade llm + dev review $$$$: high grade llm + sr dev review btw, software (past the bootstrapping phase) will get more expensive to make and take more time. quality will remain exactly the same as when humans were doing it: shit.








Introducing Tolaria! 💧 Today I am releasing a macOS desktop app for managing markdown knowledge bases, and helping both AI and humans operate them. It’s free and open source, and always will be. I have been working on it for three months, and I now use it to run my life and work. I personally have a massive workspace of 10,000 notes — the result of 6 years of Refactoring — which I now operate on Tolaria. Tolaria is the main collaboration surface with my AI agents: they create new notes there, connect them to what exists, and edit existing ones. Everything is easy to understand for them, because it’s just markdown files. In a way, it’s my implementation of @karpathy's LLM wiki. Tolaria is also the biggest experiment I have ever run about writing software with AI: • 2000 commits • 100K+ lines of code • 3000+ tests / 85% coverage • 9.9/10 code health • 70+ architecture decision records I am releasing it open source also to use it as a living artifact of how I do AI coding, so you can inspect at any time things like how I write docs, what's in my AGENTS file, what hooks do I run, and so on.
