Answer A: What is the default port number of MariaDB?
The default port is 3306. MariaDB is a fork of MySQL, and this is the default port for MySQL as well. Source.

Answer A: What is the point of triggering CI/CD with an empty git commit?
There's no point. It just causes unnecessary clutter and confusion. The correct way is to configure a manual way for triggering the CI/CD pipeline. In most systems there should be an API endpoint for this. Or e.g. in Gitlab you can just navigate to Project > Pipelines and click `Run pipeline`.

Answer A: How to compare a git stash to the current working tree?
Well it was easier than I thought: ```bash git diff stash ``` A note about the direction: This will show things which are present in the working directory but not present in the stash as added `+`. And vice versa with removed things. If this sounds counterintuitive, you can reverse it with th...

Question How to compare a git stash to the current working tree?
In git you can put your current changes aside for a moment with `git stash`. This is really neat but what often ends up happening is that you forget what was in there, and what was the state of the branch at the time of stashing. There's `git stash show`, but it only displays the differences to th...

Comment Post #290099 Yes, I wouldn't recommend writing a general purpose web server yourself, as there are good open source options to choose from. It's more of a question of how to implement the web application: As a separate process or baked into the server itself?

Unlike docker, Podman won't (understandably) use docker hub by default. You can use it explicitly like this: (just using a random example here, it's an OpenAPI linter) ```bash podman pull docker.io/dshanley/vacuum ``` But how to do it without the `docker.io` prefix?

Comment Post #290066 Yes, a reverse proxy is a good idea, but this doesn't really address the architectural dilemma of the service behind it. An interesting thought: A reverse proxy can be remarkably similar to the web server in path 1. You could say that it's just a difference of protocol (HTTP or e.g. CGI). But as ...

Question Using an existing web server vs writing your own
When writing a dynamic web service, you broadly speaking have two paths: 1. Use an existing web server (e.g. Apache, Nginx or Lighttpd) to handle the "raw" web requests and implement your own code as a separate process that communicates with the server using a gateway protocol (e.g. FastCGI). A ty...

Answer A: Git add/stage only part of a file's changes
Git's interactive mode has a patch action. This is the shortcut for it: ```bash git add --patch ``` It will split the file into hunks and interactively ask which one's to add. It has a plethora of options but selecting `?` explains them nicely: ```txt (1/2) Stage this hunk [y,n,q,a,d,j...

With `git reset`, but first, you may want to save the current state in another branch: ```bash $ git switch main $ git branch backup-of-main ``` Now the (perhaps messed up) state is safely stored in branch `backup-of-main`, and you can always just switch back to it and have another swing. T...

Comment Post #289491 How does git actually handle incomplete (local) repositories? Given that commits are changesets, just cloning a few of the most recent changes wouldn't result in anything sensible. So does it like create an archive of the history beyond the desired depth, and apply the most recent commits on that?
