Sorry, I have to disagree.
If someone comes here to search for help, he has to understand that he cannot demand help from people who are not paid. And he cannot expect to be helped in his native language or expect people to take classes to understand a request that is translated into ununderstandable rubbish by Google translate or brabblefish.
And this because he has bought a $0.5 processor and is too lazy to do his homework for university. After all, this is “engineer to engineer” and not “kid to nurse” or “we do your job for you for free” forum.
Sure, not insulting anyone is a general (rather universal) forum rule for both sides. But if someone comes here with a nickname like “BestEngineerEver” (not a reference to your forum name) and then needs help to calculate 1+1, then this is definitely a reason for a loud laugh.
The one who seeks help, and wants it for free, has to understand that it is in his own interest to make answering his question as easy as possible. Nobody here has to answer.
Alternatively, he can hire someone to do the job.
