We all know that Ada Lovelace is credited as the first computer programmer. But what did she write? What did it do? And how does it work? We look at the program, its function, and break it down line-by-line so you can understand the origins of our entire industry. After all, it doesn't get any more retro than this! In this talk, developer, geek, and digital archaeologist, Steven Goodwin, breaks down the very first program ever written to explain what it does and how it works. He goes on to simulate it within a JavaScript version of Babbage's analytical engine, rewriting it piece-by-piece until it looks like modern code, and thereby demonstrate what features of current languages we now all take for granted. He finishes up with a discussion on the controversy surrounding her involvement in computing, aiming to answer the question once and for all - "Was she really the first programmer?"
