With your index fingers you can feel a bump on the keys 'F' and 'J'. When you type you must get back to these two keys as soon as a key has been pressed on the keyboard so that you know all the time where you are on the keyboard. If you don't find the keys 'F' and 'J' again you will get lost and make a lot of mistakes. For the same reasons the first lessons are done without ever moving your fingers from these two keys.
Created in 2006 by educator Salman Khan, Khan Academy is one of the original free online-learning institutions. With step-by-step video tutorials, you can  learn how to program drawings, animations and games using JavaScript and ProcessingJS, or learn how to create webpages with HTML and CSS. See, especially, Khan's "Hour of Code," designed to introduce students to one hour of computer science and computer programming.

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)!


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.
Coding is all in the details, which is why you need to “celebrate small victories,” as one of our programming professors put it. It takes practice to make each element work on its own, as well as constant testing to ensure each line of code will work with all the rest—without errors. If you don’t do seemingly minor things right like closing a HTML tag, you’d be stuck debugging a simple syntax error rather than writing more impressive and complex code.

It does not matter how fast you type if you have to go back and fix all your mistakes. Fixing mistakes takes more time than it does to just slow down and take the time you need to type accurately. Fast typing depends on developing precision muscle memory. Allowing yourself to type incorrectly will actually reinforce your bad habits and common mistakes! Slow your typing pace until you can attain 100% accuracy. If you come across a difficult word, slow down further to type it properly. Develop good habits and speed will be your reward.

I'm Dave Henderson! For over 34 years, I've made a wonderful living for myself and family of four creating world-class water features using real and faux rock in sunny San Diego as well as professional sand sculptures all around the world. And now I'm taking what I've learned about starting successful businesses, contracting, sculpture, water feature construction, and more, and sharing it with the world. It's my mission to help people like you enjoy more success both in your business and in your personal life.

JUST RELEASED! "Makin' Rocks" covers everything I've leaned after 34 years of hard work and experience making a living building things with my hands. I teach people like you how to create the same amazing water features as a master sculptor like myself! With tons of pictures and hand drawn illustrations from decades of work you will see actual project examples of how things get done. And even how to set up your own faux rock contracting business selling $10,000, $15,000 and $20,000 or more projects! Get this book and get in the game! 

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.
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).

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?
