The Emperor's Old Clothes

By C.A.R. Hoare

Communications of the ACM, 1981

My first and most pleasant duty in this lecture is to express my profound gratitude to the Association for Computing Machinery for the great honor which they have bestowed on me and for this opportunity to address you on a topic of my choice. What a difficult choice it is! My scientific achievements, so amply recognized by this award, have already been amply described in the scientific literature. Instead of repeating the abstruse technicalities of my trade, I would like to talk informally about myself, my personal experiences, my hopes and fears, my modest successes, and my rather less modest failures. I have learned more from my failures than can ever be revealed in the cold print of a scientific article and now I would like you to learn from them, too. Besides, failures are much more fun to hear about afterwards; they are not so funny at the time.

I start my story in August 1960, when I became a programmer with a small computer

Serpents

Multi-Player Game on top of HDP protocol

The Protocol

The HDP protocol consists on 5 different messages types that share a common header with some basic user information. The protocol is defined with BNFs where ALL_CAPS_IMPLY_CONSTANTS, camelCaseImplyPrimitives and the '&' is used to denote "bitwise or" (super intuitive right?) while '|' denotes that one of multiple options can be chosen.

The Client Message Header
