Share your open source projects with the community :)
Do you work on any open source projects? If yes, please share them with the community. I am curious to see what others are working on.
My main project for the past 2+ years has been hetzner-k3s, which some here may already be familiar with.
It's a CLI tool I wrote in Crystal with the goal of making it easy and super quick to set up and manage a production-ready Kubernetes cluster on Hetzner Cloud using K3s.
The tool handles everything from creating all the necessary resources such as cloud instances, networking, firewall, load balancers, etc, to setting up the k3s and everything required to provision persistent volumes and load balancers out of the box, as well as making k3s upgrades a breeze. Autoscaling is also set up automatically, so you can configure both statiic and node pools. HA clusters are supported, both zonal and regional (at least in Europe, where Hetzner has three availability zones; clusters across continents are possible but there is a performance penalty with etcd as expected).
hetzner-k3s is by far the easiest way to set up clusters on Hetzner Cloud, since it only requires a binary and a simple configuration file. Much easier than using alternatives such as those based on Ansible or Terraform, for example, and much quicker. My record was a 500-node cluster in under 11 minutes (yes, you read that right).
The repo is here: https://github.com/vitobotta/hetzner-k3s.
The project got 3k stars on GitHub already, and is used by many people, from individuals to companies.
Now it's your turn. Don't be shy and share your projects with us! ![]()

Our most recent open source project is Multiverse Quantum Network Simulator.
It can simulate a quantum network that generates and swaps entanglements, which are provided as a resource to quantum applications running on end hosts.
The simulator currently focuses on entanglement routing algorithms.
A large network that is modeled by the simulator could become available in a decade and would cost more than ten million dollars.

Our most popular open source project is esp32cam.
It is an Arduino library for controlling a camera on ESP32 series microcontroller.
The library currently provides an object oriented interface with both synchronous and asynchronous operations.
A small device that is used with the library has been available for a decade and cost less than ten dollars.

No hostname available. affbrr
I didn't understand much of the first project, sounds very complex stuff
