Docker’s secret that most “getting started” tutorials seem to miss is docker-compose.yml. Who wants to type these long-ass commands to start containers? I always just create a compose file, and then docker compose up -d.

Dockerfile is for developers, you shouldn’t need more than a docker-compose.yml for self-hosting stuff.

Haven’t watched the video, but what do you think circularization is? If you’re “just a circulization away from orbit”, you are indeed going a bit slower than orbital velocity. There’s no point to going orbital velocity if your trajectory still brings you back inside the atmosphere. To get to orbit you want to raise your periapsis outside the atmosphere, and you do that by doing a burn at the apoapsis, which is what we commonly call “circularization”.

I use famous programmers. First Linux server was Torvalds, first mac was Woz, currently in service I have Kernighan (one of the inventors of C), KJohnson (Katherine Johnson was a programmer for NASA) and Shamir (The S in RSA).
