use protrusions in a sentence.
There are knobby protrusions on my car tires.
Part of it's high quality polish and finish is the lack of seams and protrusions and screws.
This is so funny, because ever since I was first introduced to OOP (about 19 years ago - C++), I've had visuals in my head for objects - not clear ones, but somewhere floating in there is the idea of some shape with sockets and protrusions, switches and dials, representing getters, setters, methods, etc.
Yeah my first thought on reading the article is that if enough actors cared about this they would redesign the standard for card readers so that the card goes flush into the reader without any protrusions (some are already like this) and then market this fact so that machines that aren't flat are viewed with suspicion, but I'm sure the costs to replace all the machines out there and do the marketing would be enormous at this point, and you would need buy-in from a ridiculous amount of companies so it is unlikely to happen.
