The Superheterodyne Radio: No really, that’s its name

A crystal set is very different from an FM stereo, and that’s different still from a communications receiver. We’d say there are several common architectures for receivers and one of the most common is the superheterodyne.
But what does that mean exactly? [Technology Connection] has a casual explanation video that discusses how a superhet works and why it is important.

Mastodon on your own domain without hosting a server

In other words, if you want to be discovered on Mastodon using your own domain, you can do so by copying the contents of https://<your mastodon server>/.well-known/webfinger?resource=acct:<your account>@<your mastodon server> to https://<your domain>/.well-known/webfinger.

One caveat: this approach works much like a catch-all e-mail address. @anything@yourdomain.com will match, unless you add a bit more scripting to only show a result for resources you want to be discoverable.

Edit: Seems there is a GitHub issue which requests custom domains as well.
Edit (15 Nov 2022): Folks have been using the approach of serving up webfinger on a different domain through proxy setups, e.g. using CloudFlare.
