As a windows developer that works in 3d graphics. I found this course very beneficial. An expert developer like bliblubli go step by step and cover many areas of Blender development like building, tools, patches, diff files, modifiers, cycles performance, .etc. I have search for this information only found bits and pieces. To have all of this in one place is great and huge timesaver for me.
I definite recommend this course to developers that want to start working with Blender.
