Well, that's a grand relief! I can let my breath go now!

Ah, well you see, there you're wrong. Please note that I don't deign to 
put words in your mouth. Yet, it seems that you have enough words for 
both of us! This must be my lucky day!

I have never claimed that you don't need tools on development servers. 
Yes, wireshark is k-ool and 1338 and all that...but YAGNI. Capture with 
tcpdump, carry it offline, and analyze it later.

It works for us physicists, and we found the top quark.

(Dtrace is something of a special case, for which I'd venture to say 
that I'd make accommodations for it. X11? Why? I'm still curious why 
you'd want to log onto a production server only to throw up an xcalc 
window from there? You can't run xcalc on your local machine?)

Sigh. Well, whatever, I'm sure you're the smartest person in the room 
there with yourself.

Or, alternatively, you're doing things not to make it friendly for 
users, but to make it friendly for processing. You know, computing 'n' 
The box isn't there to make the developers' lives easy. It's there to 
run the frikkin nuclear bomb simulation. While we're at it, by the way, 
it ALSO has the added bonus of making it hard for unauthorized users to 
do nasty things. Moby win!

I know I know...and you CAN do that...but you don't have to do it on 
production servers. Or you can bring in your specialized tools - when 
you need them - and take them off again. (An aside with performance 
measurement: be careful, lest you carefully measure your tools. But 
that's a different issue--one that by and large people also ignore.)

You're the smartest guy in the room there, I'm sure you and Euler can 
figure it out.

Thanks, Miles, I'm sure you're a fun guy and all, go put words in 
someone else's mouth.
