Beyond the language - An introduction to algorithms
Mastering a programming language is not enough to write efficient code. Programmers often try to squeeze a programming language as much as they can in order to achieve the best performance, without realizing that the solution could be found in a more efficient algorithm or data structure.
The talk is meant to inspire you to learn more about algorithm design by demonstrating how a properly designed algorithm may drastically increase the efficiency of your code, regardless of the Ruby version you are using.
