Re: How do you critique another person's code?
in thread How do you critique another person's code?
I agree. Remember this is not a personal attack, only a critiquing of his code. Calmly let him know that the comments are unprofessional and reflect badly on him and the company. Let his manager reprimand him for the poor choice in comments that's his job, concentrate on the code. Remind him that well used comments and understandable variables help bring real understanding as to what the code is doing. If you feel that the code needs to be rewritten show them why.
From the looks of it he needs mentoring. I am one who likes to give people a chance, but I am not suggesting that you take that job. Does he have potential? Yes, we all do. If they don't already have it suggest a code review process. bmcatt has an excellent out line. This is an excellent site for code review as well.
