Nix on macOS Catalina

I'm writing this gist for my own records but it might help someone else too.

Installing Nix

Support for Catalina has improved a lot since the update was first rolled out.

Note: See the NixOS manual for discussion of the --darwin-use-unencrypted-nix-store-volume option.

Chromium OS ft. Docker

Chromium OS is cool. Chromium OS with crouton is cooler. Chromium OS with Docker is even cooler. This is specifically a guide for the HP Chromebook 13 G1 (aka HP Spyder Chromebook), but I can't think of any reason it wouldn't work with other devices. The Chromebook Pixel 2 (2015), for example...as you'll notice, the guide this was forked from assumed that machine.

Create a build environment
Customize the kernel
Build Chromium OS
Flash Chromium OS to USB
Install Chromium OS

State: Draft
Based on the Peatio Stable branch

Coin Daemon

To the coin daemon's {coin}.conf file, include the -walletnotify command:
