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

Notes on GitHub ProjectV2 API

GitHub Projects Beta aka GitHub Projects Next aka GitHub ProjectNext is now known as GitHub ProjectV2 in the API.

It's not immediately obvious how to use the new API, especially if you're coming from the old beta API.

Convert Word documents to markdown with pandoc

$ myfilename="example"
$ pandoc \
-t markdown_strict \
--extract-media='./attachments/$myfilename' \
$myfilename.docx \

NOTE (2025-02-08)

I've since moved the tutorial over to my website. Clarified some of the wording, added exercises at the end, added links to useful resources.

For historical reasons, I'm keeping the original text here. But if you've just stumbled upon this tutorial for the first time, you may want to check out the revised version!

restic systemd configuration

1. sudo install -Dm644 restic@.service /etc/systemd/system/.
2. For each target:
   • Place the options (exclude, etc) and paths in the variable BACKUP_OPTIONS="..." in /etc/restic/TARGET/config. Newlines can be escaped with backslashes.
   • Place the repository path in /etc/restic/TARGET/repository.
   • Place the repository password in /etc/restic/TARGET/password.
3. To run the backups on a schedule, create a .timer file in /etc/systemd/system/ based on restic.timer.example, set the schedule and target unit, then systemctl enable --now whatever.timer.
4. To run the backups manually, just systemctl start it.
