Scaling Mastodon down

There is already a guide on scaling your Mastodon server up. This is a short guide on scaling your Mastodon server down.

I.e., maybe you want to run a small instance of <100 active users, and you want to keep your cloud costs reasonable. So you might be running everything on a single machine, with limited memory and CPU. (In my case, I was using a t3.medium instance with 2 vCPUs and 4GB of RAM.) How do you do this?

Note that I'm not a Ruby or Sidekiq expert, and most of this stuff I figured out through trial and error.

HoC (pattern) vs Render Props (pattern) vs Hooks (not pattern, a new API)

Someone was asking me about comparing the HoC and Render Props patterns (and their shortcomings) to hooks. I might leave this up as a public gist for others if it's helpful.

---

tldr;

Issues with HoC:

<script>
(function(){
  if (window.BOOMR && window.BOOMR.version) { return; }
  var win = window;

  function boomerangSaveLoadTime(e) {
    win.BOOMR_onload=(e && e.timeStamp) || new Date().getTime();
  }

  function boomerangLoad() {

Methods of Signing Git Commits on MacOS

Last updated March 13, 2024

This Gist explains how to sign commits using gpg in a step-by-step fashion. Previously, krypt.co was heavily mentioned, but I've only recently learned they were acquired by Akamai and no longer update their previous free products. Those mentions have been removed.

Additionally, 1Password now supports signing Git commits with SSH keys and makes it pretty easy-plus you can easily configure Git Tower to use it for both signing and ssh.

For using a GUI-based GIT tool such as Tower or Github Desktop, follow the steps here for signing your commits with GPG.
