I used docker-compose a lot, but I have never come across the collective-noun of what results from running docker-compose. I feel like calling the infra that docker-compose creates and "cluster" or a "swarm" is not entirely accurate. The technology is similar to kubernetes and docker swarm, but not exactly the same. Inferring from the name it could be a "composition", but I am not sure if that is as distinct or identifiable compared to "cluster" or "swarm".
Has anyone coined a distinct name / collective-noun for what docker-compose creates?

I am beginner in ROR. I am working on one project. I want to know the better option between for deployment of the app.
My answer will be more conceptual, rather then technical.
This is the first time I hear about Google App Engine in case of Rails. This is mostly a crucial reason, why I would say, that you definitely better go with Heroku.
While you are a beginner, it's better to use the most widely spread solutions and tools. Heroku has a huge history and you can find any answers in the internet very easily. It's well known among rails community and everyone can make a small consultation according to it.
Even if Google App Engine would be better or cheaper (haven't checked it), you shouldn't start such experiments until you have good deploy/rails knowledge.

This is a first time I use docker, so I'm trying install sql-server-linux use docker in MacOS Mojave.
I'm read tutorial from https://database.guide/how-to-install-sql-server-on-a-mac/. But I meet a problem, my database server auto shutdown.
I'm tried with sudo code but nothing change.
I'm research and nothing talk about this issue.
I have written several webcrallers and always find it easier to build them from the ground up! Scrapy is a very nice module but it's documentation is a little lacking and can be quite challenging to begin with! I recommend using BeautifulSoup4, Python bult in Urllib2, and some socket module! Good luck!

Can someone explain what is Erlang run time environment and what dose it contain? Dose it contain erlang VM, what else ?
Regards
MM
The Erlang runtime environment in particular contains the Erlang virtual machine, the kernel and the standard libraries.
Erlang in general provides a lot more tools (compiler, debugger, monitoring tools etc.).
For details, please have a look at the documentation at: http://www1.erlang.org/documentation/doc-4.8.2/doc/system_architecture_intro/sys_arch_intro.html

As a beginner & new developer attempting to learn the ropes, I am curious why we still use package managers, shell commands, and all of these things that seem like the early DOS days.
Wouldn't it seem more logical to have a GUI to simply set up an app on Heroku from Github without having to always fix all of your local environment errors and updating gems, etc?
May be a stupid question, but truly curious why it hasn't changed.
