      People target nothing specific. They just add workarounds for platforms they feel morally willing to work with.

      People target POSIX, Linux or MacOS (occasionally BSD or Windows, too). People who know what they are doing know what they are targeting.

      That's just not true. Almost every real system targets epoll/kqueue, which are non-standard interfaces.

      If they use those they aren’t targeting POSIX but maybe one of the other things I listed.

      There is no one thing to target for any of these, just "OSX" and "Linux". Calling this "Unix" is the sleight of hand.

      It implies there's something special about targeting OSX+Linux and calling it "Unix" even though there are 2 diff implementations.

      It implies to people that *Windows is harder* but really it's just a third distinct thing to target.

      In this context, for most, “Unix” means OS X + Linux. They ARE more similar to eachother than windows, by a lot. Biggest delta: path strings

      1: Yes, I think paths are a big deal. path.join is more or less good enough. Everyone going around convincing each other that it's not

      2: actually very important ("windows supports `/` yo" "uhhh not with verbatim paths") has been a huge huge regression.

      3: But I think you're underestimating epoll/kqueue shimming, compiler/linker shimming, OpenSSL/crypto shimming, etc.

          4: OSX and Linux share a path model (but not exactly a file system model), but they diverge a huge amount in general.

          5: the reason most people don't perceive that is that a lot of "Unix" libraries are actually just "shimming the union of OSX and Linux"

          6: epoll and kqueue are a good enough exemplar of this phenomenon to drive a discussion about this, but there's way more.

          7: OSX+Linux=Unix causes people to believe it's morally virtuous to write abstractions that cover "Unix" but not Windows. Usually a mistake.

          I think people do a back of napkin calculation on how much effort it'll take to support windows, and decide they have better things to do

          Think about how many more contributions you could get if you multiply potential users by 10x.

          Believe me, I've been down this path on several occasions. I've both done the extra work and not. And I've noticed no difference.

          That stuff matters, sure. But it’s solveable much more easily without leaking to the app later. Paths and signals? Nope, just pain.

          Yes, basically. “Unix” is effectively the abstraction over Linux, OS X, and (maybe) bsd or sunos.https://twitter.com/wycats/status/927590342974693376 …
