If you are interested in installing Linux, or already a user of Linux wanting better knowledge and skills, consider exploring the numerous instructional videos available on YouTube. You may not expect YouTube to carry much content for serious system builders or students preparing for IT certification, but it is there - and available for no cost. You can develop your Linux and code writing powers for free, whether you are just trying your first Ubuntu system or you are an experienced Arch Linux minimalist.
Whether the topic is Linux distributions, new software to use, or hardware reviews, it can be found somewhere on YouTube. Now, forsake those cute cat videos and never ending streams of political debates. Brew a coffee and take an hour or two to understand Bash or Fish shells. Spend a weekend learning how to patch DWM and make your Linux fast and efficient for the tasks you do. Watch and learn how Linux people refine their workflow.
