An old perl hack for generating a colored grid of cluster load from load averages collected by collectd in RRD files.
# this needs a serious cleanup/rewrite - it was hacked together
# very quickly for a completely different purpose many years ago
# and has grown in the worst organic way since
# but ... it does work fairly well so it persists

a quick & dirty yaml path printer for embedding in shell scripts
#!/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=$( roles/cassandra/vars/clusters.yml clusters/multitenant-us-east-1/availability_zones)

MPKmini2 MIDI + fluidsynth CLI only

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.


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.
