This is a nice list of tips. Since there are many different guides out there for practically any coding language, it's not hard to find information that will help. I am curious what languages you are learning? I personally know a bit of C++, Java and Android and am working on learning JavaScript.
One of the best resources Iv'e found has been www.stackoverflow.com.
The people there are very knowledgeable and you can likely find someone who has worked on the same project you are working on and has posted their own code. I'm not telling anyone this to say they can copy/paste someone elses code,(Just like your guide there says, copy/pasting won't help you learn anything),
only to say that,if you have a project you are stuck on, those guys can not only give yo advice but you can see real working code and compare it to how your code is. Lots of times, you will see a solution in the posted code to your problem before you ever have to ask a question.
