We use zebra printers all in our WH with linux workstations. I just write ZPL (similar to postscript) by hand for all our labels and our ERP application spits it out to /dev/lp0. Benefits that it requires no printer subsystem and you can send labels out to the printer at the absolute maximum possible speed.

I'll throw in the typical FOSS response. Do it yourself ;-)

They released the spec (http://www.waveprotocol.org/draft-protocol-spec) so anyone can, and in fact other have started making their own wave servers http://code.google.com/p/pygowave-server/.

Think for a moment about the other end of the spectrum of butts, the ones that you don't really want to look at but this person will invariably have to examine. One is too many for me.

While Jaunty may reboot in a short time, my servers hardware may take several min to reboot while they scan SCSI chains, attach iSCSI devices, wait for timeouts for various LOM cards to click by, etc... long before linux comes into play.

Are you talking USD?
I've never heard anyone offering 40k/year for an actual sysadmin, I was making that when I was 18 doing front line help desk. Heck, a quick google says the median is ~70k and I'm willing to bet the t-mobile sysadmins make a bit more than that (well, if this story is true - they are pulling in unemployment now).

BSD systems of course include OS X http://www.afp548.com/article.php?story=20060214081244545

Also if you have your UPS's in the server room you have one (or more) less heat generating step-down transformer.

When given the opportunity to design my current server room from scratch I got 208VAC into the room. But yes your correct, I do get some strange stares from people when they ask why all my PDU's have IEC-14 sockets (both to denote that this is not 'normal' 120VAC, and also so there is no live metal prongs exposed when plugging and unplugging devices).
