Cloudflare DDNS bash client with systemd

This is a bash script to act as a Cloudflare DDNS client, useful replacement for ddclient.

Look out!

A newer version is available!

This gist will no longer update, instead please go to https://github.com/lifehome/systemd-cfddns for more updated versions.

How to use?

1. Put the cfupdater files to /usr/local/bin

• If you are using IPv4 for A record, append -v4 to cfupdater in the following systemd service unit.

When you need to set value to "UV_THREADPOOL_SIZE"?

• Libuv has a default thread pool size of 4, and uses a queue to manage access to the thread pool - the upshot is that if you have 5 long-running DB queries all going at the same time, one of them (and any other asynchronous action that relies on the thread pool) will be waiting for those queries to finish before they even get started.

• Note, however, that tuning UV_THREADPOOL_SIZE may make more sense for a standalone application like a CLI written in Node.js. If you are standing up a bunch of Node.js processes using the cluster module then I would be surprised if tuning UV_THREADPOOL_SIZE was particularly beneficial for you. But if your application resembles the web tooling benchmarks then tuning UV_THREADPOOL_SIZE may help with performance.

<script> async, defer, async defer, module, nomodule, src, inline - the cheat sheet

With the addition of ES modules, there's now no fewer than 24 ways to load your JS code: (inline|not inline) x (defer|no defer) x (async|no async) x (type=text/javascript | type=module | nomodule) -- and each of them is subtly different.

This document is a comparison of various ways the <script> tags in HTML are processed depending on the attributes set.

If you ever wondered when to use inline <script async type="module"> and when <script nomodule defer src="...">, you're in the good place!

Note that this article is about <script>s inserted in the HTML; the behavior of <script>s inserted at runtime is slightly different - see Deep dive into the murky waters of script loading by Jake Archibald (2013)

Pure ESM package

The package that linked you here is now pure ESM. It cannot be require()'d from CommonJS.

This means you have the following choices:

1. Use ESM yourself. (preferred)
   Use import foo from 'foo' instead of const foo = require('foo') to import the package. You also need to put "type": "module" in your package.json and more. Follow the below guide.
2. If the package is used in an async context, you could use await import(…) from CommonJS instead of require(…).
3. Stay on the existing version of the package until you can move to ESM.

VirtualBox only supports the x86 platform, so the default installation instructions for Vagrant does not work on Apple silicon. Thankfully Vagrant has a VMWare Provider (more on providers here), and so if I can get VMWare running on my M1 MacBook, I should be able to run Vagrant as well!

These are my notes during figuring this out.

Get the VMWare Tech Preview released in September 2021!

We are in luck, as VMWare released this just a few weeks ago.
