About & Joona Viertola


This website was build for and idea to keep learning notes somewhere. At the same time these may help others and advertise me. Primary value of most content is that they are written for myself. So there is no long step-by-step manuals. More like a easy to pick notes.

Another reason is that I learn new stuff by trying to explain them. What would be better way than this?

Also I have listed books I've read about programming: Books I've read
