Open Source Crystal Command Line Tools

irs is a command-line application that downloads audio and metadata in order to package an mp3 with both. Extensible, the user can download individual songs, entire albums, or playlists from Spotify. Note that the binaries right now have only been tested on WSL. They should run on most Linux distros, and OS X, but if they don't please make an issue. At it's core irs downloads individual songs. It does this by interfacing with the Spotify API, grabbing metadata, and then searching Youtube for a video containing the song's audio. It will download the video using youtube-dl, extract the audio using ffmpeg, and then pack the audio and metadata together into an MP3. From the core, it has been extended to download the index of albums and playlists through the Spotify API, and then iteratively use the method described for downloading each song.

This is a CLI tool to quickly create and manage Kubernetes clusters in Hetzner Cloud using the lightweight Kubernetes distribution k3s from Rancher. Hetzner Cloud is an awesome cloud provider which offers a truly great service with the best performance/cost ratio in the market. With Hetzner's Cloud Controller Manager and CSI driver you can provision load balancers and persistent volumes very easily. k3s is my favorite Kubernetes distribution now because it uses much less memory and CPU, leaving more resources to workloads. It is also super quick to deploy because it's a single binary. Using this tool, creating a highly available k3s cluster with 3 masters for the control plane and 3 worker nodes takes a few minutes only. The tool assigns the label cluster to each server it creates for static node pools (this doesn't apply to autoscaled node pools), with the cluster name you specify in the config file, as the value.
