I can’t recommend Harvard’s CS50x Introduction to Computer Science enough. You can audit the course for free via edX and earn a certificate by completing all the assignments, or you can go at your own pace and watch all the lectures posted on Youtube. You can build your own DIY college-level computer science program with this selection of fifteen online courses (many of which are also listed in our Lifehacker U series).
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.

Third, Keybr.com lets you introduce as few keys as possible to the lesson, adding more keys automatically when it decides that you are proficient at the current level. When you only start learning it generates lessons with words from a very small alphabet of the most frequent letters. When your typing speed for every key in that alphabet reaches certain threshold, the algorithm adds the next most frequent letter to the alphabet. And so on, until the next letter. This way you will learn the most frequent letters first, and the least frequent ones later.

TypeLift provides a visual keyboard to help you learn to type in a quick and simple way. Coloured keys show you the right finger-key-combinations and the basic positions. Visual markers show you how to reach every key on your keyboard. So you don’t have to search on your „real“ keyboard anymore from the start. However, advanced users can disable settings on the visual keyboard to improve their personal learning curve.
Based out of New Zealand, Code Avengers provides fun and interactive programming lessons for kids 5 to 14; for schoolteachers wanting to teach coding; for people going into coding professionally; and for creators ages 15 and up. Also offered are one- to three-day "code camps" for students up to 17. These day camps are located in multiple states -- and foreign countries.
