Even more pro tips: * Let the list moderator (ahem, that would be me) deal with policing the behavior of the list participants.
* Realize that this list is publicly archived and indexed by search engines. Realize that potential employers often Google applicants. Realize your behavior here, as such, is "in public" and reflects on you for better or worse. * Seriously, LET THE LIST MODERATOR DEAL WITH POLICING BEHAVIOR. If you feel like you *absolutely* *must* *say* _SOMETHING_ -- say it directly to me. If it just can't wait for email, I'm on IRC on freenode and irc.perl; /msg genehack and I'll respond. Otherwise, if you find yourself responding, on-list, in a confrontational way, STOP. Just don't send that email. Please. * The whole thing with calling out other peoples responses is getting really old. If you think somebody gave a bad or uninformative response, the best way to deal with that is to write a better one, and explain why it's better, ideally without specifically referring to the other person's post. * Remember that we're here to help Perl beginners. We're not here to snipe at each others answers. That doesn't help beginners. Thanks to all the beginners asking questions, and all the people providing answers (and sorry for not being one of those people more often). You are all appreciated. thanks, john. -- John SJ Anderson / geneh...@genehack.org On Tuesday, June 5, 2012 at 11:08 AM, Jack Maney wrote: > ProTip: If you're going to ask for help, don't insult and dismiss out of hand > the findings of those who take the time to help you. > > -----Original Message----- > From: John W.
