-## Practice Coding
+## Programming
+
+Practicing DevOps without knowing programming is like eating cornflakes with ketchup - it's just doesn't makes sense... (yes, my analogies are the worst).
+Here is a list of some good sites to practice programming in general:
 
 Name | Comments
 :------|:------:
 [HackerRank](https://www.hackerrank.com) | Practice Coding skills
 [Exercism](https://exercism.io) | Over 48 languages and 2600 exercises
 [LeetCode](https://leetcode.com) | Practice programming online
 
+A better approach might be to actually write some DevOps related scripts or projects. Start simple. Here are some ideas:
+
+  * Write a script that gets a number of instances and a name of a platform (AWS, local, Azure, ...) as parameters and provisions those instances on the chosen platform
+  * Write a script to parse logs and extract some specific information you are interested in
+
+### Operating Systems
+
+Deep dive into operation system internals. I would say choose Linux but I must admin I'm biased.
+If you did choose Linux, here is a list of resources that will help you learn Linux

+[Techmint Linux](https://www.tecmint.com/free-online-linux-learning-guide-for-beginners) | Written articles/lessons
+[Linux Survival](https://linuxsurvival.com/linux-tutorial-introduction) | Interactive guide
+
+Once you are familiar with the commands and feel comfortable enough to keep deep diving, learn some OS concepts:
+
+  * Memory Management
+  * Processes
+  * Kernel
+  * Virtulization
