Setting up NixOs with LUKS encrypted root

Here are my working notes on getting a system up and running.

WARNING: You can run into a hidden problem that will prevent a correct partition setup and /etc/nixos/configuration.nix from working: if you are setting up a UEFI system, then you need to make sure you boot into the NixOS installation from the UEFI partition of the bootable media. You may have to enter your BIOS boot selection menu to verify this. For example, if you setup a NixOS installer image on a flash drive, your BIOS menu may display several boot options from that flash drive: choose the one explicitly labeled with “UEFI”.

switch/case in Python

A manner of replicating the functionality of switch and case in other languages using variable type arguments to Python's except keyword.

Dynamic except

Python's except keyword takes as an argument either a type or tuple of types specifying what exceptions to capture (you can also bind the exception object to a variable, but we don't care about that right now.) it functions like so:

Using Mastodon with Backblaze B2

Mastodon can store its assets in Amazon S3 (it speaks the S3 protocol). But it does not, by default, speak to Backblaze B2.

There are a couple of reasons why you might want that:

• you already know and trust B2
• it's cheaper
• you do not want to make your instance dependent on AWS
• etc.
