Thunderbolt Networking Setup on Linux

This guide documents the steps to enable and configure Thunderbolt networking on your Linux system (e.g., Ubuntu, Proxmox). It covers loading the necessary kernel modules, ensuring persistent interface naming, configuring a fixed IP address, and testing throughput with iperf3. Note that Thunderbolt 3/4 hardware advertises a raw bandwidth of 40 Gbps, but practical throughput is typically lower due to half‑duplex operation, protocol overhead, and system constraints.

Hardware Used in This Guide

This guide was developed and tested with the following hardware:

CPU: AMD Ryzen 9 PRO 6950H
- 8 cores / 16 threads
3.3 GHz base frequency / 4.94 GHz boost

ProxMox Cluster - Soup-to-Nutz

aka what i did to get from nothing to done.

note: these are designed to be primarily a re-install guide for myself (writing things down helps me memorize the knowledge), as such don't take any of this on blind faith - some areas are well tested and the docs are very robust, some items, less so). YMMV

Purpose of Proxmox cluster project

Making a board compatible with VIA Configurator

💥NOTE💥: Don't do this yet, all of this stuff is still 🚑💣BLEEDING EDGE💣🚑, and you will 🔪cut yourself🔪 badly if you choose to do it. Please wait for 🗿Wilba's QMK code to be refactored prior to pushing anything to QMK, as we don't want to end up with a bunch of different forks of the code.

So you've seen VIA Configurator in action, and you want to get this magic supported for your board?

There's two main steps:

Add dynamic keymap support to keyboard in QMK
Add layout to VIA

Home Assistant Lovelace Migrator

Do you want to try out this experimental (!) new lovelace UI stuff in Home Assistant but don't want to migrate your entire configuration? This script is here to help! It reads in your Home Assistant configuration (specifically the group: section) and creates a matching ui-lovelace.yaml file in your Home Assistant configuration folder (of course backing up any previous file at that path).

To use this script, you first need to have python and home assistant installed where you plan to run this script. Do so using virtual environments and the pip3 install -U homeassistant command. Then copy below file to lovelace_migrate.py (any location should work) and run:

python3 lovelace_migrate.py -c <PATH_TO_HASS_CONFIG_DIR>

This is now moved here: https://home-assistant.io/lovelace

How we're using dry-monad

Imagine that we have an application where user's have a location. We want to find the weather for their current location using an external service call. We want to provide this functionality in a json api. A basic implementation might look like this.

def create
 user = User.find(params[:id])

	import { Controller } from 'stimulus';

	export default class extends Controller {
	connect() {
	this.select2Mount();

	document.addEventListener('turbolinks:before-cache', this.handleCache);
	}

	disconnect() {

	<?php

	function camel_to_snake($input)
	{
	return strtolower(preg_replace('/(?<!^)[A-Z]/', '_$0', $input));
	}
	function snakeToCamel($input)
	{
	return lcfirst(str_replace(' ', '', ucwords(str_replace('_', ' ', $input))));
	}

	# Define ULID_DECODE and ULID_ENCODE which convert a ulid string to a binary and vice versa.

	delimiter //
	DROP FUNCTION IF EXISTS ULID_DECODE//
	CREATE FUNCTION ULID_DECODE (s CHAR(26)) RETURNS BINARY(16) DETERMINISTIC
	BEGIN
	DECLARE s_base32 CHAR(26);
	SET s_base32 = REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(REPLACE(UPPER(s), 'J', 'I'), 'K', 'J'), 'M', 'K'), 'N', 'L'), 'P', 'M'), 'Q', 'N'), 'R', 'O'), 'S', 'P'), 'T', 'Q'), 'V', 'R'), 'W', 'S'), 'X', 'T'), 'Y', 'U'), 'Z', 'V');
	RETURN UNHEX(CONCAT(LPAD(CONV(SUBSTRING(s_base32, 1, 2), 32, 16), 2, '0'), LPAD(CONV(SUBSTRING(s_base32, 3, 12), 32, 16), 15, '0'), LPAD(CONV(SUBSTRING(s_base32, 15, 12), 32, 16), 15, '0')));
	END//

	update-grub && update-initramfs -u -k all
