// ...and can be used to detect/polyfill the `signal` argument to addEventListener.
//
// Note that at writing, 86%+ of active browsers already support it:
//   https://caniuse.com/mdn-api_eventtarget_addeventlistener_options_parameter_options_signal_parameter
// ...but that 92% of browsers support `AbortController` and signal.
//
// So there's 6% of total browsers which will fail silently when adding the `signal` argument.
// Eyeballing it, this is mostly Safari 11-15 and Chrome 66-90. These snippets can help with those targets.

Raspberry Pi on Internet via reverse SSH tunnel

HackerNews discussed this with many alternative solutions: https://news.ycombinator.com/item?id=24893615

I already have my own domain name: mydomain.com. I wanted to be able to run some webapps on my Raspberry Pi 4B running perpetually at home in headless mode (just needs 5W power and wireless internet). I wanted to be able to access these apps from public Internet. Dynamic DNS wasn't an option because my ISP blocks all incoming traffic. ngrok would work but the free plan is too restrictive.

I bought a cheap 2GB RAM, 20GB disk VM + a 25GB volume on Hetzner for about 4 EUR/month. Hetzner gave me a static IP for it. I haven't purchased a floating IP yet.

Basic Tetris HTML and JavaScript Game

This is a basic implementation of the game Tetris, but it's missing a few things intentionally and they're left as further exploration for the reader.
