Go Command-streaming lib for distributed systems (3x faster than gRPC)
I created cmd-stream-go, a high-performance client-server library based on the Command Pattern, where Commands are first-class citizens. Why build around Commands? As serializable objects, they can be sent over the network and persisted. They also provide a clean way to model distributed transactions through composition, and naturally support features like Undo and Redo. These qualities make them a great fit for implementing consistency patterns like Saga in distributed systems. On the performance side, sending a Command involves minimal overhead — only its type and data need to be…
Go Command-streaming lib for distributed systems (3x faster than gRPC) launched on July 22, 2025 with 12 votes, #1,378 of 9,223 launches that month and more than 75% of that year's launches. The site was still online in September 2026, 1 year on.
In plain words
cmd-stream-go is a Go library for building distributed systems using the Command Pattern, where commands are serializable, network-transmissible objects that can be persisted and composed. It supports features like Undo, Redo, and distributed transaction patterns such as Saga. Designed for developers building consistency-critical distributed systems, the library emphasizes performance with minimal serialization overhead, using either MUS or Protobuf formats for data transmission.

go-nbd – A Pure Go NBD Server and Client2023 · github.com · ▲113Hey HN! I just released go-nbd, a lightweight Go library for effortlessly creating NBD servers and clients. Its a neat tool for creating custom Linux block devices with arbitrary backends, such as a file, byte slice or what I'm planning to use it for, a tape drive. While there are a few partially abandoned projects like this out there already, this library tries to be as maintainable as possible by only implementing the most recent handshake revision and baseline functionality for both the client and the server, while still having enough support to be useful. I'd love to get your feedback :)
Go Micro – A distributed systems development framework2020 · go-micro.dev · ▲115I can't tell if HN is the right kind of place for this stuff anymore since people are so advanced in their use but I thought it was interesting to leverage my existing Go microservices framework and turn it into the core of what would provide tools for an agent cli or whatever beyond that. Extensibility is key. Thought I'd share and get a conversation going.

Today marks ten years, 3653 consecutive days, of running at least one mile every day under the USRSA rules [1]. To celebrate, I built an interactive dashboard that turns a decade of GPX files into charts you can explore. Running has truly changed my life: I've made lifelong friends, explored beautiful places, and more importantly invested into my own health and fitness, which I'm starting to see the positive benefits as I get older. The stack is pretty simple: a NextJS app, with a Postgres database to keep all my running data, and all the stats are pre-computed and cached in Redis, so I…

Made this website as an exercise in vibe-coding and GCP. It was posted about a few times around the internet, on sites like Morning Brew (https://www.morningbrew.com/issues/business-buzzkill), MetaFilter (https://www.metafilter.com/209703/Draw-A-Fish), boingboing.net, etc. I think it's cute! I built a basic CNN trained against penises and swastikas, and then anything that doesn't hit the 63% confidence score gets sent to a mod queue, a vibe-coded fish-tinder…

Hi HN - I made a site that takes a UK postcode, grabs the local MP's information and generates an AI mockup of what their ID might look like. It's a small, silly protest at the stupidity of the Online Safety Act that just came into force. edit - My open AI credits got hugged to death, please use a known postcode (like one from Kier Starmer's constituency, WC2B6NH) in the meantime.
