Indeed many changes to start off optimistically:]

Pretty much just learned how to use the board, the components, wiring of things and how to use a breadboard.

Also I have been really frustrated to learn that arduino ides and bunch of other things work absolutlely terrible under linux and not only. It even works buggy ways within Windows (i also tried legacy versions and achieved the same conclusion).

Anyways, not really much to detail other than my learning process.
