Of course no offense, but the author does seem to be somewhere shortly after the first peak on the Dunning-Kruger curve. Even truly embedded systems with an OS like QNX don't "melt" with 100 threads. Obviously he "doesn't know what he doesn't know" in expertise terms, and blamed a mistake on the operating systems. That combined with the other extremely dubious reasoning - e.g. (see my other very long comment) how replacing state machines with callback functions is a good idea (tm). There is also the comment RE: "how bad Windows APIs are" and how IO-completion ports are '_actually_ pretty nice'. This is the kind of comment someone makes if their worried the "real" coders won't take them seriously if they use anything but Arch Linux. Makes you think he is reasoning about things that he just isn't an expert in yet (embedded systems, operating system APIs, long-term framework design). Nothing wrong with that though - everyone has to build up experience somehow - but maybe a bit early to be on the front page of HN.
