Becoming C++ guru, I mean in professional way. My 2017 mean focus on C++ as much as possible, then apply for C++ job abroad ! (I think about going to Europe or US).
p.s. I have bachelor degree in CS, and my theoretical (specially in Design and Analysis of Algorithms and Operating Systems) foundation is rock solid, maybe same level of a last year graduate student from ordinary university (not top-notch of course). But I need to learn more about Compilers and Programming Languages and their underlying technology, and I have chosen C++ as language that I want to spend my career on. So 2017 for me means C++ ! (and a little bit of Rust).
Another things I really like to get my hands really dirty is build tools. I do use CMake for my personal projects, but I want to learn Autotools, Meson, gn, etc. Because I fucking hate build tools, so I think knowing more and more, is good idea to understand whats going on in build tools area.
p.s. I wish next year this time, I can look at past and proud myself! I wish, wish me success HN!
