Why watch
Russ Cox walks through solving Advent of Code 2021 Day 24, a puzzle involving an Arithmetic Logic Unit (ALU) with a custom instruction set (inp, add, mul, div, mod, eql). This is a compiler/interpreter problem where participants must build a simple virtual machine in Go to process 14-digit serial numbers. Ideal for developers interested in algorithm challenges, VM construction, and seeing how Go excels at systems programming.
