An old perl hack for generating a colored grid of cluster load from load averages collected by collectd in RRD files.

tobert / yamlpath.py
Created Feb 6, 2018
a quick & dirty yaml path printer for embedding in shell scripts
View yamlpath.py
#!/bin/env python3
#
# this is NOT a human-facing tool
#
# This is to replace the legacy data files being used to populate
# variables in a shell script and instead get them from the vars
# files even though that still feels weird.
#
# Example:
# azs=$(yamlpath.py roles/cassandra/vars/clusters.yml clusters/multitenant-us-east-1/availability_zones)

Akai MPK Mini 2 + Fluidsynth + Linux synthesizer

This is a quick & dirty way to attach an Akai MPK mini 2 USB MIDI controller to Linux so the Linux machine can act as its synthesizer. This approach should work for any modern USB MIDI instrument.

Rationale

I looked around on the web and, surprisingly, I didn't find any simple options for quickly starting Fluidsynth up and wiring it to a MIDI controller for simple keyboard usage. There are a few out there that involve using Qsynth which is cool but I didn't want a GUI for something relatively simple.
