you do know the real fight was tunny. Enigma was battalion level. Tunny was divisional. This was 501 bit digital encryption which required a computer to be built in 1943 in london

why does every /sci/ faggot talk about how much theoretical CS sucks but every math PhD candidate I've met has nothing but good things to say about complexity theory or algorithms, provided they took those classes?

Computer Engineer here (unlike cs fags I actually know about computers). I too had to take these courses and they suck, they are a bunch of completely theoritical bullshit, completely detached from reality, with near no actual use in the real world. Before anyone considers defending cs, please answer to yourself how is it possible that there are algorithms with lower time complexity which are actually slower when run on a real machine (for all n or for very large n of course)

Enigma was broken before ww2 by polish mathematicians.

Oy vey goy, the poles didn't exist then, the only victims of the nazis were jews and the only victors were antifascists. The defense pact is not valid if our greatest ally, the (((soviet))) jewnion wants to invade, only the bad nazis. Now send us all the cryptography data so we can take credit for it and help you become a progressive communist shithole. What do you mean there is no official alliance with the soviet union in 1939? Oy vey you are right! Ugh... don't ever learn about that part of history, we definetly aren't behind every nation so we can't bring even "enemies" together when someone threatens our power! You are starting to become antisemitic with all those questions goy!!!

Because time complexity is a theoretical measure of performance not a practical one. It’s cute that studying applied computer science aka computer engineering makes you feel superior.

So you come to my words that theoretical cs is crap and detached from reality
But uhm.... do you really think im cute?

Theoretical aspects of a discipline are detached from reality by definition. This doesn't mean they're useless. I can smell the freshman on you from over here.

All these people were just playing an autistic mental game when they came up with ground breaking theoretical ideas.

Most of the problems solved there arose from the practical needs of making something work instead of jacking off to proofs and complexity though?

A bit too on the Nose. Try being more subtle.

Commercial and early ones - yes. But the military one needed improvement introduced by Turing and other, polish bomba stopped working as Enigma got improved early in the war.
