What it does
Today we're releasing Connect, a slim framework for building browser and gRPC-compatible HTTP APIs. Connect is production-ready — focused, simple, and debuggable — and it's fully compatible with gRPC clients and servers.
Simple, reliable, interoperable: Protobuf RPC that works.
Connect is a family of libraries for building browser and gRPC-compatible APIs. If you’re tired of hand-written boilerplate and turned off by massive frameworks, Connect is for you. Connect shines in production. Implementations are focused — a few thousand lines of code, a handful of essential options, and a cURL-friendly protocol — which makes them stable, predictable, and debuggable. In addition to its own protocol, Connect servers and backend clients also support gRPC — including streaming! They interoperate seamlessly with Envoy, grpcurl, gRPC Gateway, and every other gRPC implementation. Connect servers handle gRPC-Web requests natively, without a translating proxy.…from connectrpc.com

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

I've seen some interests in (simulation) video games here on HN so I thought I'd share a short version of our story. More than 6 years ago, me and my friend from university were playing around with an idea of making a game we always wanted to play. We worked on it on weekends but the progress was quite slow, especially due to so many dead ends and wasted effort. Eventually however, we solidified our direction and decided to take the risk to resign from our well paid SWE jobs and work on it full time. It took more than a year but yesterday we have finally released it on Steam:…
