> @puwad what are you goals in programming? I have to many goals to realize them, i think one of first things i need is to feel how much i can do alone because my ideas could be hard to realize by myself. It is several apps for windows such as a gui for [everything search engine](http://voidtools.com) that have sdk. And vst plugins to process signal, because i'd like to process audio signal. Now i stuck with some ideas that i can't find anywhere (i know all vst's are on c++ but maybe i will find some way) and think that i should do something to bring them to life. But first of all I should say that I like concept of Jupyter notebooks and think that all material for beginners should be in this format. So my idea here - learn Nim and at the same time port lessons to Jupyter notebook format. I don't know how to do that but here is [jupyter nim kernel last updated one year ago](https://github.com/stisa/INim) So i think my first tasks will be in this field.
