The Two-Bit History blog discusses Ada Lovelace’s published computer program, often called the world’s first computer program. She wrote a program for a computer that had only been described to her. But. her program was never run, because the computer she was targeting was never built.
It’s the intricacies of Lovelace’s program, though, that make it so remarkable. Whether or not she ought to be known as “the first programmer,” her program was specified with a degree of rigor that far surpassed anything that came before. She thought carefully about how operations could be organized into groups that could be repeated, thereby inventing the loop. She realized how important it was to track the state of variables as they changed, introducing a notation to illustrate those changes. As a programmer myself, I’m startled to see how much of what Lovelace was doing resembles the experience of writing software today.
The article discusses history of Babbage and computing and implementation of Lovelace’s work in C and Python.
Adafruit has had paid day off for voting for our team for years, if you need help getting that going for your organization, let us know – we can share how and why we did this as well as the good results. Here are some resources for voting by mail, voting in person, and some NY resources for our NY based teams as well. If there are additional resources to add, please let us know – adafruit.com/vote
