Think twice before abandoning Xorg. Wayland breaks everything!

Hence, if you are interested in existing applications to "just work" without the need for adjustments, then you may be better off avoiding Wayland.

Wayland solves no issues I have but breaks almost everything I need. Even the most basic, most simple things (like xkill) - in this case with no obvious replacement. And usually it stays broken, because the Wayland folks mostly seem to care about Automotive, Gnome, maybe KDE - and alienating everyone else (e.g., people using just an X11 window manager or something like GNUstep) in the process.

Conversion to a combined PEM file

To convert a PFX file to a PEM file that contains both the certificate and private key, the following command needs to be used:

# openssl pkcs12 -in filename.pfx -out cert.pem -nodes

Conversion to separate PEM files

We can extract the private key form a PFX to a PEM file with this command:

This has caused a not-inconsiderable amount of trouble! But finally, I've fixed copypasta:

Terminator

enable global -> smart copy (only affects mapping of ctl-c if text selected)
Disable profile -> copy on selection

copyq

store clipboard
store text using mouse
^^paste clipboard with mouse^^

How to remove node_modules

Safest way to clean up boot partition - Ubuntu 14.04LTS-x64, Ubuntu 16.04LTS-x64

Reference

Case I: if /boot is not 100% full and apt is working

1. Check the current kernel version

$ uname -r

	#!/bin/bash
	#this script is intended to decrapify your Ubuntu, stuff like turn off unattended upgrades...
	echo 'some of this should be done as root'

	echo 'creating pubip'

	# Ensure the directory exists
	mkdir -p /root/scripts

	# Write the script content to the file

	#!/bin/bash

	#usage: mysql-drop-all-tables -d database -u dbuser -p dbpass

	TEMP_FILE_PATH='./drop_all_tables.sql'

	while getopts d:u:p: option
	do
	case "${option}"
	in

	Command used for testing:
	dd if=/dev/zero of=sb-io-test bs=1M count=1k conv=fdatasync && rm sb-io-test
