alt Hacker NewsThis is a great example of something that experience has dragged me, kicking and screaming, into grudgingly accepting: That ANY time you say “We will absolutely always only need one of these, EVER” you are wrong. No exceptions. Documents? Monitors? Mouse cursors? Network connections? Nope.
Testing is such a good counter example. "We will absolutely always only need one of these EVER". Then, uh, can you run your tests in parallel on your 128-core server? Or are you forced to run tests sequentially one at a time because it either utterly breaks or accidentally serializes when running tests in parallel? Womp womp sad trombone.
