I am surprised nobody has mentioned Language Transfer. I haven't listened to the Music Theory course, only the Spanish one, but I can highly recommend it:

I have been using enpass, and I'm very satisfied. I was a LastPass user once, but never trusted their security model. Then switched to 1password, but the lack of good multiplatform support and their push to a cloud model made me look for alternatives. What I want is support for Mac, Windows, Linux, and Android; possibly one time payment; and local storage (most important). For syncing I use my own nextpass cloud. Bitwarden is close, but enpass fullfills all.
Why do you need Docker for a simple PHP & MySQL script? To install it you just need to setup a MySQL database and enter the credentials in the setup script. Finally, add the tracking code to your site, but that's the same for every analytics engine.
Actually, after the ban of the cars, the manufacturers looked for other races where they could use their monsters. They took them to Dakar, and to the famous Pikes Peak hillclimb race in the USA. Peugeot made a very good movie about it (although it is in a 405T16, which technically never raced group B, the car is basically a 205 T16 with another body shell) - https://www.youtube.com/watch?v=UEuZG37gFdM
