    Project mention: How types make hard problems easy | news.ycombinator.com | 2024-12-19

    This is hand-wavey, but that can't be true: less complex type systems manage to express all kinds of interfaces correctly all the time.

    You're asking me to tell on my coworkers, and I'm too loyal to throw them under the bus :)

    Well, OK, here's one, but I'll keep it as blameless as possible. We had a thing where we wanted to register some event handlers. The primary use of these event handlers was to run a selector, and if the selected data changed, trigger an update, passing the selected data along. The initial implementation used existential types to store a list of callbacks, each returning different selected data. The "driver" then did the equality checking and update triggering. We later changed this, so that the callbacks - as far as the driver was concerned - all returned `void`, eliminating the need for an existential type. We just had to move the equality checking and update triggering inside the callbacks.

    Some features are straightforward translations: anywhere you have overloading and/or optional arguments you can (and often should) simplify by refactoring into multiple functions.

    For a concrete, public example...well, I remember the Uppy library had a lot of stuff like this. A lot of work goes into making it's "Plugin" interface look the way it does (start at [1] and keep reading I guess), and while I haven't sat down and re-engineered it I don't think it needs to be this way, if you're willing to give up some of the slickness of the interface.

  11. void

    Project mention: Anthropic co-founder on cutting access to Windsurf | news.ycombinator.com | 2025-06-05

    Void is basically the same thing, but open source and better. It's easy to use with any provider API key, even LM Studio for local models. You can use it with free models available from OpenRouter to try it out, but the quality of output is just as dependent on the model as any other solution.

    I have been spending a lot of time exploring AI Coding Assistants like Amazon Q Developer to see how they can help open source developers, and Ricardo Tasso came up with a great example in how he is using Q Developer to generate deployment configurations for Kubernetes. He has written this up in his post, Creating Deployment Configurations for EKS with Amazon Q so go check it out (you can get started with Amazon Q Developer for free by registering your Builder ID here). Langfuse is an open source LLM engineering platform that helps teams collaboratively develop, monitor, evaluate, and debug AI applications. AWS Community Builder Matsuda shows you how you can deploy this, using CDK to make it simple. If this sounds like something you are interested in, go read the post Self-Hosting Langfuse v3 on AWS Using CDK.
