Codewars adds some quirk to the proceedings by offering free coding classes with a martial arts theme. Solving specific coding “katas” (a term for training exercises in karate) will earn you ranks and honors as you move your way to becoming a bonafide coder. Who said learning to code online couldn’t be fun? Codewars also offers one of the more diverse lists of programming languages. Choose free coding classes on:
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)!
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.

What an incredible app. I’m so impressed. This company deserves loads of money to be thrown at it for making it free. My son has just switched from a Cambridge school to an American School and missed a lot of work. I think we were both about to give up. I didn’t know where to start to help him and being his new school is completely iPad based we felt deep despair at just the thought of trying to navigate through classrooms codes and half working text book apps. Now it’s all here in one place! Simple well explained and the practice really gets your confidence going. He had some maths homework and instead of the total melt down we both would have had trying to work out what was going on we flew through it!! THANK YOU! I love the fact that all the grades are here too so if there is a concept he is struggling with we can go back in the grades to see where that was introduced and work through it! We have been struggling for months trying to find the answer on line. It was only due to the fact that Khan kept coming up that I googled it and found the app. I truly pray this company gets loads of financial support to keep this app going! THANK YOU THANK YOU THANK YOU!!
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).
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.

Touch typing is the ability to use muscle memory to find keys fast, without using the sense of sight, and with all the available fingers, just like piano players do. It significantly improves typing speed and eliminates errors. Touch typing simply makes you more productive and it is a skill worth learning. However, many people engage in the bad habit of ‘hunt-and-peck’ typing, even those seasoned professionals with years and decades of computer experience. It  is easy to understand, though, as touch typing requires dedicated practice to  learn it well.

My name is Jamie Spencer and I have spent the past 5 years building money making blogs. After growing tired of the 9-5, commuting and never seeing my family I decided that I wanted to make some changes and launched my first blog. Since then I have launched lots of successful niche blogs and after selling my survivalist blog I decided to teach other people how to do the same.
The programming community is full of people who are willing to help the next generation of programmers. GitHub, the online hangout for developers who use Git to manage their coding projects, is designed for online collaboration. Not only do developers host and share their projects with their peers, they also provide code feedback and general advice to the community.
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?

This is our best piece of coding advice: If you can’t figure out why your code is broken, you can always look for solutions online. You’re probably not the first person to make your mistake, after all, and someone on the internet has surely already found a solution to your issue. Just “copy and paste” your error message into Google (or your preferred search engine), add a pair of quotation marks around the entire phrase so that you’re not just searching for keywords, then hit “Enter.” Hopefully, this little trick will lead you to the correct answer.
