A quick search of the internet reveals a plethora of tutorials for programmers. No one has time to read even a minuscule fraction of the available material.
What you need is a curated list of tutorials. Better than that. A curated list of the finest free tutorials. Free and open source tutorials still have a cost — your precious time. And just because a tutorial is free/open source doesn’t, itself, signify any great quality to the work. Hence the need for recommendations for free tutorials to help you learn C, C++, Java, Python, R, or whatever language takes your fancy.
The tutorials we recommend will help increase your technical skills and make you proficient in the language of your choice. And some of them even provide a little light relief on the way. Humor can be a great aid to learning.
If you need more in-depth information, we recommend you check out our series on the best free programming books. They offer a deeper foundation in learning the relevant programming languages. Many of the books we recommend offer a solid foundation in learning the relevant programming language. Some are very specialist, some offer a quick overview.
