Data Visualization in Clojure using ggplot2 from R

We'll be using the ClojisR library to visualize data in Clojure. This library is a Clojure-R interop and it allows us to call R functions on R objects in Clojure.

Usage requirements

Before starting ensure that you have the following installed on your computer:

JDK 1.8 or later
Clojure 1.9.0 or later
R

Recurrent Neural Network for generating piano MIDI-files from audio (MP3, WAV, etc.)

https://github.com/BShakhovsky/PolyphonicPianoTranscription

A python program which performs an FFT on an audio file and produces a MIDI file from the results

https://github.com/NFJones/audio-to-midi

Extract the melody from an audio file and export to MIDI

https://github.com/justinsalamon/audio_to_midi_melodia

Performs pitch detection on a polyphonic audio source and outputs to MIDI

Raspberry Pi on Internet via reverse SSH tunnel

HackerNews discussed this with many alternative solutions: https://news.ycombinator.com/item?id=24893615

I already have my own domain name: mydomain.com. I wanted to be able to run some webapps on my Raspberry Pi 4B running perpetually at home in headless mode (just needs 5W power and wireless internet). I wanted to be able to access these apps from public Internet. Dynamic DNS wasn't an option because my ISP blocks all incoming traffic. ngrok would work but the free plan is too restrictive.

I bought a cheap 2GB RAM, 20GB disk VM + a 25GB volume on Hetzner for about 4 EUR/month. Hetzner gave me a static IP for it. I haven't purchased a floating IP yet.
