GitHub Actions is a good example of systems thrown together that at face value have something to offer until they get put under stress.
Just now I found:
* a job that's > 1 month old, still running
* another job that started 2 hours ago that had 0 output
* a job that was marked as pending, yet I could rerun it
* auto-merges that don't happen
* pull requests show (1), click it, no pull requests visible
Makes me wonder in how many places state is stored, because there is some serious disconnect between them.
That's just post-Windows 8 Microsoft quality for you. Every product has been like that - looks "ok" on the outside (in reality it looks shit, but at least that's intentional), but the second you dig deeper and start using it you get all kinds of paper cuts like that.
