Somewhere in one of the magazines scattered on my office floor I read "When you hear hoofbeats, think horses not zebras". The author wanted to make the point that we should think about the common things before we think about the exotic ones.
How many times have you heard people assign to perl, or the operating system, or whatever, some really weird, buggy behavior? Every week I see another message in a Perl newsgroup asking "Bug in PERL?". Very few have had any merit.
I wonder what separates the people into the horses and zebra groups. Maybe I could do something about it if I knew. No, probably not.
