Very much this! As a person who recently completed a medium-sized C project I can say the author's work is simply IMPRESSIVE on so many levels. It's true that there's no error checking and there's undefined behavior, but please note that the author is rather young and this project is in a usable state. All of these issues can be added/fixed with time as the author learns more about the language and programming in general. The author got good experience and this is what counts here. Clearly, the author is willing to get some practical coding experience next to the theoretical foundations he learns about at the university. I can only support that and sadly I didn't have this mindset while studying CS. The way I see it, the author had an idea, sat down, put it to practice and implemented a functional prototype which can easily be expanded upon. This is probably how all these arcane *nix tools we use today came into existence. I don't imagine anyone wondering "should I use a rope or something more efficient, let me just spend 2 months trying out different structures" while coding one of the first text editors. Also, what the author did would not be simple to achieve in ANY language, because no language out there has a ProduceVimLikeEditorWithMinimalFeatures() function.
