1&2) Yes, you're right. All popular operating systems out there are more or less plagued with the same issues. I'm not bashing GNU/Linux (or any other OS) here - I use it and it's a good system. My only point is, that designing protocols (as opposed to designing apps/services) doesn't really help to get rid of inconsistencies and bring compatibility. Sometimes, yes, I bet having a well-defined protocol saved many from inventing their own. But - in my personal perceptions (and I surely could be wrong) - not even remotely enough. 3) They're not hard, just inconvenient to some degree. Given enough time and patience, everything can be worked around (and there are compatibility wrappers/hacks). But - honestly - it's still a mess, both on the surface and under the hood. I really don't want to even think that this particular file picker is unaware of "recent documents" list of another framework. Don't want remember that PgAdmin3 has its own peculiarities interacting with clipboard and selection. And, back to the original article's topic, surely don't even ask myself whenever a smart bulb would be compatible with some phone app, especially one that I may haven't even encountered yet. @Unrelated: Thanks for the advice. I don't use those features either. Although I don't have any complaints with PA, next time I'll have time and consider messing up with my system I guess I'll give JACK a try.
