Your answer can help determine which programming language(s) you should master, as well as what sort of commitment (in time and money) your goal may require. For example, if your dream is to create the next great operating system or a killer alternative to PhotoShop , you would benefit from a formal computer science education that teaches you C++, as well as more complex topics like data structure, algorithms and memory allocation.
Touch typing, or blind typing as some calls it, means that you type without looking at the keyboard. To learn to do that finger position is very important. When you type you must use specific fingers for the same keys all the time as illustrated at the image above. If you don't do that you will soon loose your orientation and make mistakes. When you have found the two home keys, 'F' and 'J', you should strive to type with out looking at the keyboard. Look instead at the two hands at the virtual keyboard on your screen. Don't get frustrated if you do mistakes in the beginning. Every one does. After exercising for some time you will know by heart where the keys are and your touch typing will go much more smooth.
Also, something that I've found is that if you go wrong somewhere instead of mindlessly searching for the error (assuming there are multiple or you don't know the error's location) just start from the beginning and go down seeing that if this works. If you see a break and something disconnects, in all probability that's where the error is. It's all logic.
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.
