An easy counterargument is that sockets support out of band read operations: for example, I can call getsockname() on a socket to obtain meaningful information about it after shutdown(). Pipes have no such analogue. Also, it's a gene

I think the results are very interesting: just to reiterate, I would love to see what you've done here, and I hope you publish it. Obviously, it's your right to decide... but especially if you think of it as a hobby, why not relea

My biggest gripe is the villains. I want stories that challenge my expectations, not a litany of ham fisted cold war allegories.

That blog isn't very authoritative, and doesn't go into any detail at all. > I'd imagine every computer relies on redundant stick/pedal encoders, which is how a 12-way notion appeared. That's disingenuous at best

I definitely agree the real environment is more challenging in a holistic sense. What I meant is that in a real airplane, you have the advantage of things like G-force, force feedback from the reversible controls, stall buffet, the sound of

Generally an over-reliance on the instruments. Not looking out the front window as the primary means of judging the aircraft's attitude, not navigating visually. Also, not using trim in a realistic way (looking at you, magical set-trim

Flying a real airplane is easier than flying a simulator, because you have so much more sensory input available. Because of this, you are likely to teach yourself bad habits in the simulator that will be expensive to unlearn in a real airpl

Most pilots would prefer a visual approach given the choice. I doubt this pilot actually believed it would be unsafe to fly the visual at SFO that evening: given the dozens of other jets actively doing it, that would be absurd. He was just

Flagging a cab on a busy road in NYC is always faster than waiting for an Uber, at least in my experience. I prefer to pay cash, personally. Denying finance parasites their 2% fee is always worth an extra ten seconds of my time.

This almost always works, I think it's absolutely hilarious. Often the operator who picks up seems surprised I'm polite... I think it shows them a "this guy is really angry" warning sometimes.
