That sinking feeling when you search for how to do something and all of the top results are issues that were opened over a decade ago...
It is especially painful trying to use github to do anything useful at all after being spoiled by working exclusively from a locally hosted gitlab instance. I gave up on trying to get things to cache correctly after a few attempts of following their documentation, it's not like I'm paying for it.
Was also very surprised to see that the recommended/suggested default configuration that runs CodeQL had burned over 2600 minutes of actions in just a day of light use, nearly doubling the total I had from weeks of sustained heavy utilization. Who's paying for that??
