Provide agents with automated feedback
Back pressure for agents You might notice a pattern in the most successful applications of agents over the last year. Projects that are able to setup structure around the agent itself, to provide it with automated feedback on quality and correctness, have been able to push them to work on longer horizon tasks. This…

Why we don’t use AI
We get asked about AI a lot. Whether we’re going to add it to Yarn Spinner, whether we use it ourselves, what we think about it. Fair questions. Time to write it all down. Yarn Spinner doesn’t use the technology that’s currently being called AI. We don’t have generative AI features in the product, and we don’t use…

LLVM: The bad parts
A few years ago, I wrote a blog post on design issues in LLVM IR . Since then, one of these issues has been fixed fully (opaque pointers migration), one has been mostly fixed (constant expression removal), and one is well on the way towards being fixed (ptradd migration).
