Send email from Cloudflare Workers via MailChannels

Cloudflare announced a partnership with MailChannels that allows you to send free email via workers.

The example code that MailChannels supplied wasn't working so I fixed it here to make testing easy.

Add include:relay.mailchannels.net to your domain's SPF record.
Update the code below with your email addresses
Create worker, paste code, save and deploy and test

Deploy Next.js static to GitLab pages

Create a basic GitLab CI config:

$ cat .gitlab-ci.yml
image: node

before_script:
 - npm install

Overview

Scenario

Your VPS provider doesn't support ISO mount
Your VPS has low RAM and cannot load whole ISO image
Your current /boot is to small to contain ISO file

Workaround

Boot low memory ISO (CorePure64.iso ~ 14MB)
Create new partition ~1GB / size of your ISO
dd your ISO into that partition

Host Your Site Under Your Domain on IPFS

This is a step-by-step tutorial for hosting your website under your domain on IPFS, from zero, on a DigitalOcean Ubuntu 16.04.3 x64 Droplet (i am using the $10 variant with 2GB RAM).

Install IPFS

Log in as root.

First, make sure the system is up to date, and install tar and wget:

	import 'dart:convert';

	import 'package:flutter/foundation.dart';
	import 'package:riverpod_annotation/riverpod_annotation.dart';
	import 'package:shared_preferences/shared_preferences.dart';

	import '../../../constants/db_keys.dart';
	import '../../../controllers/common_controllers.dart';
	import '../../extensions/custom_extensions.dart';

	#!/bin/sh

	SERVICES=$(echo "$DEPENDENCIES" \| tr "\|" "\n")

	resolve()
	{
	for SERVICE in $SERVICES; do

	ip=$(nslookup "$SERVICE" \| awk '/^Address: / { print $2 }')

	import 'dart:async';
	import 'package:meta/meta.dart';
	import 'package:hasura_connect/hasura_connect.dart';
	import 'package:http/http.dart' as http;

	// problem:
	// when subscribing to`HasuraConnect.subscription`, a websocket connection is created on the first subscription
	// call. The websocket connection is created only once with the initial subscription and the provided TokenInterceptor
	// or headers. When the token expires during an active subscription, HasuraConnect doesn't stop the subscription, or try
	// to reconnect with the latest token in in the TokenInterceptor nor does it throw an error. It'll keep calling `onRequest`

	HOSTNAMEOPTS="-n alpine"
	INTERFACESOPTS="auto lo

	auto eth0
	iface eth0 inet dhcp

	TIMEZONEOPTS="-z UTC"

	import { useState, useEffect, useRef, EffectCallback } from 'react';
	import throttle from 'lodash/throttle';
	import debounce from 'lodash/debounce';

	// Ties two states together, and tracks only if a specific case occur.
	export const transitionTracker = <A, B>(from: A, to: B) => {
	let marker = 0;

	return (state1: A, state2: B) => {
	if (from === state1 && to === state2) {
