Came here to post this same link but you beat me to it! Big Clive's videos are brilliant—highly recommend his channel to anyone remotely interested in electricity/electronics.

This is a fantastic and well-written guide, thank you!

I recently wrote a toy caching DNS proxy in Elixir, and I have a question which I’ve never been able to figure out. Individual DNS records for the same hostname can have different TTLs configured. For example, 30s for one record and 300s for another. As a caching resolver, what is the expected behaviour when the record with the shorter TTL has expired but the other has not? I chose to invalidate the entire thing and make a new query upstream, but I’ve always wondered what the “proper” behaviour should be.

1Password for Mac allows you to do this also.

Agreed. I've used Vim as my editor for as long as I can remember, and combine it with make if a project needs some kind of compilation or post-processing step. The flexibility of using it alongside a powerful general-purpose text editor means you can basically do anything, without the need for an IDE. Even writing mobile apps, and you get a better understanding of what's going on "under the hood" as well.

We have considered this actually, and I think it will be something we look into more as our scale increases. As you say, we already have the communication infrastructure in place via Celery/RabbitMQ.

We haven't evaluated RQ specifically, since RabbitMQ is a core part of our infrastructure and we're really happy with it. We have experienced the pain of managing Celery, and considered alternatives a few times though! A post about our experiences there is on the list to write! :)
