A little on what I do...
I work for my computers, like everyone will in the future.
My specialty is making stuff talk to each other. You can slap two Windows servers onto the network and odds are they'll be chatting back in forth in no time, but try and make that Windows 2003 server talk to the Novell server that's trying to download SQL data from a Linux box that's using an older version of NIS to authenticate... oy. Oh, and the client wants single sign-on too.
There's the vey.
Did I mention the client wants to be able to print the results of this SQL query to an LPR printer? From his ancient Mac that's running OS 7, and that they can't upgrade because it's running an add-on card from a company that went out of business 5 years ago?
