Using randomness to ensure row uniqueness is a bad solution. Since I only started working a few months ago, my only experience with peers had been with fellow students. I remember several WTF stories from college, such as when one of the groups spent a full day writing their own full-text search instead of using the LIKE %search_string%. Maybe we should just be glad he didn't build his own processor first However, messing up like this is accepted and also useful while in college. I bet he learned a lot during that day.

On the other hand, I was talking to a developer at work and was surprised by how many previous colleagues he had known that never read the manual. If you do not read the manual, how do you know the function you are calling do what you are guessing it will do? I guess you don't because you are just copy and pasting, huh?

If you ever are writing code for something important you should always read the manual. If you do not read the manual, a nasty bug will happen and it will bite hard. Because the bug had been easy to understand if you just had read the manual, this flaw will reflect very badly on you.
