The Setup

I wanted to write a module that generates multiple systemd services and timers to scrub some zfs pools at certain intervals. The default scrub config does not support individual scrub intervals for each pool.

I want the config to look like this:

{
  services.zfs-auto-scrub = {
 tank = "Sat *-*-* 00:00:00";

Overview

Internet connection and DNS routing are broken from WSL2 instances, when some VPNs are active. The workaround breaks down into two problems:

Network connection to internet
DNS in WSL2

This problem is tracked in multiple microsoft/WSL issues including, but not limited to:

microsoft/WSL#5068

Talon Voice Commands Cheatsheet

This is a demo for how to get a cheatsheet of all Talon voice commands.

To recreate what I did:

Have talon installed on your computer following the instructions at talonvoice.com
Paste both the cheatsheet.py and cheatsheet.talon into the user directory of ~/talon. This makes these scripts available to talon.
Open the talon repl and type

	# Module for configuring libvirt with static NixOS networking
	# instead of using libvirt managed bridge.

	{ config, lib, pkgs, ... }:
	with lib;

	let
	cfg = config.virtualisation.libvirtd.networking;
	v6Enabled = cfg.ipv6.network != null;
	v6PLen = toInt (elemAt (splitString "/" cfg.ipv6.network) 1);

	# Edit this configuration file to define what should be installed on
	# your system. Help is available in the configuration.nix(5) man page
	# and in the NixOS manual (accessible by running ‘nixos-help’).

	{ config, pkgs, ... }:
