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.)
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.
