[karlgoethebier]: marioroy: Racket ball is considered harmful, like Squash
[marioroy]: Wait till folks see what MCE::Hobo can do in the upcoming release. Multiple instances, nested spawning, 3 levels, doesn't matter. it works on Windiows too.
[Lady_Aleena]: I hate sites that tell me to turn ad-blocker off. They should know better.
[marioroy]: s/Windiows/ Windows/
[Discipulus]: marioroy can you expand that Niagara's fall history?
erix only sees fallen angels
erix if it weren't for bad luck, I'd have no luck at all
Discipulus Windiows the OS of native americans..
[karlgoethebier]: marioroy: Next step: Write the ultimate book. "Parallel Programming With Perl. Yet Another Missing Manual" ;-)
[marioroy]: karlgoethebier I do not do Racket ball anymore. That was from gym class long ago.
