set -e, -u, -o, -x pipefail

The set lines

These lines deliberately cause your script to fail. Wait, what? Believe me, this is a good thing.
With these settings, certain common errors will cause the script to immediately fail, explicitly and loudly. Otherwise, you can get hidden bugs that are discovered only when they blow up in production.

set -euxo pipefail is short for:

set -e
set -u

Transmission Blocklist

The Transmission torrent client has an option to set a Blocklist, which helps protect you from getting caught and having the DMCA send a letter/email.

It's as simple as downloading and installing the latest client:

Jellyfin API Authorization

To start using the Jellyfin API, authorization is probably the first thing you'll need to do. Jellyfin's authorization options can be a bit confusing because there are a lot of deprecated options.

Generally there are three ways to authenticate: no authorization, user authorization with an access token or authorization with an API key. The first way is easy, just do nothing. But most often you'll need to use either the access token or API key.

Sending authorization values

There are multiple methods for transmitting authorization values, however, some are outdated and scheduled to be removed. It's recommend to use the Authorization header. If header auth isn't an option, the token may be sent through the ApiKey query parameter. Sending secure data in a query parameter is unsafe as the changes of it leaking (via logs, copy-paste actions or by other means) are high. Only use this method as a last resort.

Solving Freebuds 3 volume problem on Linux

My freebuds 3 had a very low volume on Ubuntu 18.04 until I saw this answer. So running the following command 4 times resolved the issue

dbus-send --print-reply --system --dest=org.bluez /org/bluez/hci0/dev_<mac_address_of_headphones> org.bluez.MediaControl1.VolumeUp

Just note that the mac address should be seperated with _ underscore rather than : which you may find in the bluetooth settings.

	#!/bin/bash

	dbus-monitor --system "type='signal',path='/org/freedesktop/UPower/devices/battery_BAT0',member='PropertiesChanged'" \| while read LINE; do
	echo ${LINE} \| grep battery_BAT0 \| grep -q PropertiesChanged
	if [ $? -eq 0 ]; then
	BATT_STAT=$(dbus-send --print-reply=literal --system --dest=org.freedesktop.UPower /org/freedesktop/UPower/devices/battery_BAT0 org.freedesktop.DBus.Properties.Get string:org.freedesktop.UPower.Device string:State \| awk '{ print $3; }')
	if [ $BATT_STAT -eq 1 ] \|\| [ $BATT_STAT -eq 4 ]; then
	LEVEL=$(powerprofilesctl list \| grep -q performance && echo "performance" \|\| echo "balanced")
	elif [ $BATT_STAT -eq 5 ]; then
	LEVEL="balanced"
