[marto]: good morning all
[Corion]: Hi marto!
[Corion]: The fun show at $work continues, as The Big Project is now in its second week of frantic live-bugfixing and weekend releases where nobody knows what went live. Nothing has been tested anyway.

Corion watches from the sidelines. Or rather, from behind, as my system only gets output from that process and my programs adhere strictly to the GIGO design principle.
[erix]: ah, that's nice to hear Corion :)
[Corion]: erix: Yeah, the sad thing is that all I can do is document things, so I can point fingers when the auditors come :-/
[Corion]: "I'm here to open tickets and point fingers. And I'm all out of tickets."
[erix]: didn't Sybase have pretty good auditing? :) (this is a vague memory)
