wetransfer.com lets you send files up to 2 GB around the world for free.
But exactly how many bytes are in 2 GB?
CS majors would probably go with 2 * 1024^3 = 2147483648, but files that big get rejected.
So, should we count like the storage manufacturers and calculate 2 * 1000^3 = 2000000000?
Well, turns out files as big as 2 * 1024^3 - 1 = 2147483647 are ok, with one byte left.
Looks like someone used < instead of <= for the size check
