The Cloudflare outage was a good thing

Cloudflare, the CDN provider, suffered a massive outage today. Some of the world's most popular apps and web services were left inaccessible for serveral hours whilst the Cloudflare team scrambled to fix a whole swathe of the internet.

And that might be a good thing.

The proximate cause of the outage was pretty mundane: a bad config file triggered a latent bug in one of Cloudflare's services. The file was too large (details still hazy) and this led to a cascading failure across Cloudflare operations. Probably there is some useful post-morteming about canary releases and staged rollouts.

Update 2025-07-16: Use either Revanced, NewPipe or Firefox with add-ons. Revanced is my personal pick, due to it being a mod of the official App like Vanced, but better (e.g. it has integration of Sponsor Block, Return YouTube Disklike and more).

I wouldn't recommend Kiwi Browser anymore as it has been discontinued. AFAIK it has been accuired by Microsoft and the extension support has been merged into Edge (Canary). But you'd have to use Edge. Yuck.

Instead of checks like:

if (value === null) {
  throw new Error("missing value")
}
doSomethingThatNeedsValue(value)

Hassy's Hammerspoon Config

Just like its website says Hammerspoon is staggeringly powerful (and also staggeringly fun). This is my Hammerspoon config. It's very simple, but it allowed me to replace two other apps: Spectacle for moving windows around, and Karabiner which I used for quickly switching between apps.

This is where it all began:
