There is a hat named IDENTIFICATION DIVISION which can be earned by earning a silver badge. The hat name is in all caps.
Is the naming in all caps purposefully, or is this a bug?
No, this is on purpose.
IDENTIFICATION DIVISION is a statement in COBOL, see this Hello World program:
DISPLAY "Hello, world!"
Because it's the first line in a COBOL program, it's aptly placed first in the Winter Bash hats overview.
Now we all luxuriate in encodings like UTF-16 and the frankly obese UTF-32, it's occasionally nice to travel back a generation or two and use text that can be encoded in DEC SIXBIT and perhaps even earlier.
This hat showcases such encodings.
Some programmers especially those using COBOL and even early FORTRAN dine out on this sort of thing.
