I just can not understand how this thing works.

I am engineer, and I may be sensitive to user experience, or just a bad engineer but I do not get this. I read ALL the guides available in the last 5 hours,

this

this

and downloaded all of these files that has 0 meaning, 0 explanation, only tones of libraries called "SDK". A kit for development should have 1 visible file, that you can click and start writing your code.

I can not seems to understand, in simple words, where are you writing the lines of code and push the button to program the chip ? the actual window/editor/file that does that ? where is this software ?

People build such powerful tools and makes long comprehensive guides, and yet a hardware engineer with a master degree just can't figure out where the hell I edit and flash my code ???

Well, you first need an IDE, these are by default supported by the SDK. Using Keil you can flash the application by simply pressing the F8-key or the "Load" button, super-easy!:

.

If you are using e.g. GCC, you can also flash using nrfjprog

Not sure if "you" means me or Nordic Semi in your posts but that doesn't matter much. I'm afraid there is a misconception about this forum: it's bunch of people (from which couple are Nordic employees, you can identify them by blue rectangle around the icon and comment in their profile) who can help you if you have specific problem. We cannot change the world. We cannot develop free gorgeous IDE and SDK and libs for you on a spot. If you want to give feedback to Nordic it's much easier to contact them directly through My Page or their sales guys. I'm sure that if they hear similar feedback from important customers and they can improve it they will. But that's nothing we can help you with here and now.
