I recognize that programmers often start counting at 0.
I'm not sure how this connects to 0 being lonely, since that means it's getting used. Even if the programmers are lonely, I still do not get it. Can someone explain?
There's an old saying that goes, "One is the loneliest number." Non-programmers usually start counting at one, making it the first number in the count.
Programmers generally have to start counting at 0. So to them, the first number is 0. So the joke is that a non-programmer would say "one is the loneliest number" a programmer would say "zero is the loneliest number" because the numbers they start with when counting are different.
You're correct, Google just returns results for The Beatles because enough people search for that rather than Three Dog night, and I wasn't paying attention
