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'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.
When you reverse-engineer someone else’s code, testing each line to see how it works, you get a better understanding of the big picture. Thanks to the tons and tons of open-source code that’s out there, you can learn just about anything by examining someone else’s (flawless) work. Just remember to share your code back with the community if inspiration strikes and you improve a part of the program you were fiddling with.
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.
