Bigger question for me was when does one truly learn C? Finishing C course on college didn't felt like I learned C. Nor implementing some common algorithms and data structures. [Lets mark my experience until this moment as `phase 1`] This attitude made me stay in C for a bit longer, getting my self interested in systems programming and that is when I got to see truly what programming and debugging C really is. I was learning and experimenting for 2 years with that, and I felt recently like I was ready to move on, (Python and Clojure taking over for the most part) and the conclusion was rather strange: Everything after phase 1 didn't brought me that much, considering cost/benefit factor I was not impressed by the end results. While whole first few years and college in C were significant and I recommend it to everyone to learn C even up to a point where you write basic CRUD program that read some data from txt/bin and create linked list with that data and represent it, my venture into systems and lower level programming didn't bring me as much of "general" knowledge. Sure it was good, and I learned C++, and combining those two now I do some other things that are related to the things I learned during that period (like GPGPU), it wasn't that mindblowing as I expected initially.
