My last question brought up some discussion about application notes and (bad?) practice. See the comments under the various answers.
Until now I thought: "Ok these application notes are written by electrical engineers working at some big companies, who probably know what they are doing."
But after reading the comments from my last question, I dont know whom to trust. If I had been studying electrical engeneering or had enough pratical experience, I probably would have enough knowledge to see bad practice / wrong application notes. But I am just a hobbyist.
So what should I do? Just go ahead and hope, that everything works fine, until something breaks. So I know the next time: dont do this. According to the comments in the linked question, this could be realy frustrating, because some faults come and go randomly. Maybe I do not even realize, that the design I took from the application note was wrong. I would probably search for a mistake in my design, because I am the unexperienced guy...
One thing I have learned so far from the comments in the other question is, that I should always look through the datasheets and search for things that exceed the operation ratings of the devices (it is not safe to just stay within the maximum ratings).
Is there anything else I should check in an application note, so I could identify a probably bad design and ask someone (e.g. here), whether it is realy bad design?
