Show HN: Hearth – a shared family workspace where an agent can build appshttps://news.ycombinator.com/item?id=49292004Hi HN — I built Hearth for my family: https://ourhearth.aiHearth is a shared workspace for a household. We use it for plans, notes, schedules, people, and recurring family rituals, with an AI agent that can work across that context. Kind of like a shared Obsidian with an agent.The cool part is that the agent can also build apps on top of the family's notes and run them inside the same workspace. We have a calendar and a travel app, for instance, and all the apps I use to manage my company's operations are in another Hearth.Hearth is built on Playground, a library we're developing for building collaborative AI coding harnesses. The common primitives are synchronized files, agents, people, app code sandboxing, and a policy layer.

Show HN: I built a fast RSS reader in Zighttps://github.com/superstarryeyes/hysWell, I certainly tried. I had to, because it has a certain quirk inspired by "digital minimalism."The quirk is that it only allows you to fetch new articles once per day (or X days).Why? Let me explain...I want my internet content to be like a boring newspaper. You get it in the morning, and you read the whole thing while sipping your morning coffee, and then you're done! No more new information for today. No pings, no alerts, peace, quiet, zen, etc.But with that, I needed it to be able to fetch all articles from my hundreds of feeds in one sitting. This is where Zig and curl optimisations come in. I tried to do all the tricks in the book. If I missed something, let me know!First off, I'm using curl multi for the network layer. The cool thing is it automatically does HTTP/2 multiplexing, which means if your feeds are hosted on the same CDN it reuses the same connection. I've got it configured to handle 50 connections total with up to 6 per host, which seems to be the sweet spot before
