If you google “skr mini e3 v2 pinout” you can find 5v and ground pins. The question is how much load is already on it’s 5v regulator and how much are you adding.
You can power the pi from a buck converter or from whatever else.
They apparently make an addon 5v buck converter for that board.
Using a multimeter could help avoid frying more stuff.
For a single new problem that hasn’t yet been automated I use CLI utilities to collect information to use to write code for a new automation.
I use web UIs to monitor metrics (grafana) and write custom exporters to collect metrics that can show performance or potential issues and logs.
I normally buy them on release day if it looks like a game i want to play. The bugs don’t seem to bother me that much and I dont come across as many spoilers that way.
I’m a programmer myself, and it’s interesting for me to think about some bugs. Maybe that’s part of the reason why I don’t understand all of the hate.
My best advice is to avoid people who yell at you. You can express your boundaries and let whoever know how that makes you feel, and what you can’t accept.
If the yelling isn’t retaliatory from some bad thing you did to them, you could also ask them if they are okay.
I learned them and basically never use vim.
I use sed if i need to change things with a pattern, cat the file if i need to see the contents, use head or tail if its too much to fit on the screen.
If I am writing code, I use a code editor. Emacs and vim can do a lot, but they can also fuck off.
