It’s a VGA connection and, yes, my primary concern is resource usage. I’m running 2-3 VMs on it so that I can easily migrate the VM around.

I had plain old top and it was boring. I did not know how many alternatives there were.

I’ll also have to check out cmatrix.

This is an excellent idea!

Generally, no. On some cases where I’m extending the code or compiling it for some special case that I have, I will read the code. For example, I modified a web project to use LDAP instead of a local user file. In that case, I had to read the code to understand it. In cases where I’m recompiling the code, my pipeline will run some basic vulnerability scans automatically.

I would not consider either of these a comprehensive audit, but it’s something.

Additionally, on any of my server deployments, I have firewall rules which would catch “calls to home”. I’ve seen a few apps calling home, getting blocked but no adverse effects. The only one I can remember is Traefik, which I flipped a config value to not do that.
