Debian 13

Caution Upgrading from Debian 12 to Debian 13 on machines with mdadm has intermittently failed for me; symptom is that grub EFI is not up to date and system boots into BIOS. Root cause under investigation; it might not be related to mdadm.

To start, read the official release notes.

If your install fits into "vanilla Debian plus maybe a handful of 3rd-party repos", then this guide for a simple upgrade to Debian 13 "trixie" from Debian 12 "bookworm" can be helpful. 3rd-party repos are handled with a find command.

Note upgrade is only supported from Debian 12 to Debian 13. If you are on Debian 11, upgrade to Debian 12 first. Then once on Debian 12, you can upgrade to Debian 13.

Supercharge Your Bash Workflows with GNU `parallel`

GNU parallel is a command line tool for running jobs in parallel.

parallel is awesome and belongs in the toolbox of every programmer. But I found the docs a bit overwhelming at first. Fortunately, you can start being useful with parallel with just a few basic commands.

Why is `parallel` so useful?

Let's compare sequential and parallel execution of the same compute-intensive task.

Imagine you have a folder of .wav audio files to convert to .flac:

	#!/bin/sh
	#
	# This git hook should let us prevent commits from containing words that we sometimes use
	# as "sky is blue" proof that a method is working when it's behaving strangely.

	disallowed="poop fart poopy farty shit fuck"

	git diff --cached --name-status \| while read x file; do
	if [ "$x" == 'D' ]; then continue; fi
	for word in $disallowed

	# attempt 6, success
	# relies on Magisk auto start script
	# pause script to give wireguard time to autostart
	bullhead:/ # cat /data/adb/service.d/prep_gateway.sh
	#!/system/bin/sh
	sleep 2m
	su -c 'iptables -F tetherctrl_FORWARD'
	su -c 'sysctl -w net.ipv4.ip_forward=1'
	su -c 'iptables -A FORWARD -i tun0 -j ACCEPT'
	su -c 'iptables -t nat -A POSTROUTING -o rmnet_data0 -j MASQUERADE'
