Do you have a smarthome device like the Amazon Echo? You can put your coding skills to the test by creating customized mini-programs to get more functionality out of your devices’ digital assistants. Amazon’s Alexa may already know many basic voice-command “skills,” like reading the latest news headlines, but you can teach her more complicated tasks by coding in Node.js, Java, Python, C#, or Go. (Or, if you want to start with something easier, try the simpler Alexa skill blueprints site.)
AGupieWare is an independent app developer that surveyed computer-science programs from some of the leading institutions in the U.S. It then created a similar curriculum based on the free courses offered by Stanford, MIT, Carnegie Mellon, Berkeley and Columbia. The program was then broken into 15 courses: three introductory classes, seven core classes and five electives.
EdX is another leading online-learning platform that is open source instead of for-profit. It was founded by Harvard University and MIT in 2012, so you know that you’ll learn about cutting-edge technologies and theories. Today, edX includes 53 schools. You probably can’t go wrong with the free Introduction to Computer Science from Harvard University.
