Diagnosing spurious wakes

This gist documents my attempts to get to the bottom of spurious wakes after installing Ubuntu 20.04 LTS on my system.

Initially, I thought it might be another system on my network sending Wake-on-LAN (WoL) packets. Then I thought it might be a known XHCI spurious wake kernel issue. And lastly, I finally resolved things by actively disabling the ability of USB devices, e.g. the mouse, to wake the system.

Update: I later came up with a better way of disabling wake-on-mouse that's covered here.

Note: as one of these steps, I upgraded the system BIOS - while this didn't resolve this particular issue, it did resolve an annoying issue with the graphic state not being properly restored for certain applications after wake-up.

Encrypting hard drives without reinstalling Ubuntu
===================================================
Gijs van Tulder, 26.02.2019, last update 04.03.2019

This is a list of the steps I took to encrypt the partitions on my
Ubuntu 16.04 laptop with the LUKS encryption system. Encrypting the
partitions took some time but was relatively easy. Getting the system
to boot afterwards was a little trickier, but doable.

Obviously, these steps might not work for you. Follow them at your

Interactive Matplotlib (while in REPL)

Matplotlib can be used in an interactive manner either in the REPL or as part of a script. Let's assume you're using export MPLBACKEND='Qt4Agg'.

To do this you need to switch on interactive mode:

import matplotlib.pyplot as plt
plt.ion()

# Why do you want this ? Because Git will see diffs between files shared between Linux and Windows due to differences in line ending handling ( Windows uses CRLF and Unix LF) 
# This Gist normalizes handling by forcing everything to use Unix style.

Adventures in Python Core Dumping

After watching Bryan Cantrill's presentation on [Running Aground: Debugging Docker in Production][aground] I got all excited (and strangely nostalgic) about the possibility of core-dumping server-side Python apps whenever they go awry. This would theoretically allow me to fully inspect the state of the program at the point it exploded, rather than relying solely on the information of a stack trace.
