Ah yes the Raspberry Pi, a charitable project intended to get young kids into coding, which comes with kid-friendly projects, brightly coloured beginners' guide books, and pre-installed with Scratch, is truly only a tool for experienced professionals.
Yes, if he/she was using it for that (kid projects, Scratch, etc.) it would have been the right tool. Maybe it's because she skipped all those steps in his/her IT education is the reason he/she is having troubles now.
I learned about the devicetree on a RPi too, but I didn't complain about it in a blog. When I bought my first RPi I expected to encounter problems and learn a lot from solving them. In fact, I expected it to be much much worse - so much worse that I even bought the RTC module even before the RPi arrived in the mail. Why didn't he/she think of that? It's because he/she is lacking the basics, the kid project with gpio leds and i2c sensors.
