On the other hand, if you’re a mid-career professional looking to transition into a tech career, a short-term coding bootcamp might make more sense than going into debt for a second degree. If all you want to do is build websites or push your Raspberry Pi to its limits, a combination of interactive tutorials and free online courses might be enough to get you going.
Learn using videos, interactive exercises, and in-depth articles in math (arithmetic, pre-algebra, algebra, geometry, trigonometry, statistics, calculus, linear algebra), science (biology, chemistry, physics), economics (microeconomics, macroeconomics), humanities (art history, civics, finance, US history, US government and politics, world history), and more (including computer science principles)!
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.
Right away you can see that Hackr.io has numerous programming languages you can learn. After selecting the course you want to take, it will first direct you to a list of tutorials where you will be able to filter the course to your liking.  You can select free or paid, as well as, beginner or advanced, and in which language you would like to be taught.
Take a few minutes (or a day) to think about the reasons—the real reasons—why you want to learn a programming language. Be honest with yourself. Are you trying to learn the barest minimum to score a promotion? Are you looking to make a big career change? Do you want to create the next greatest app? Thrill your roommates by programming your various smart devices to do something awesome?
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.
