I work in the information assurance area at Johns Hopkins University Applied Physics Lab. I am a senior IA professional. When did network and computer security become "information assurance," and why? I do understand that the idea of "information assurance" (IA) sounds broader than "computer and network security," but is it really? The "I" in "IA" is broader, but practically IA addresses information on computers and networks, not information residing in file cabinets or on bookshelves.

Why and when did this change?

There are many ways to tell amateurs from the pros. When traveling to a 5-day conference, the pro does not check bags. When watching someone give a briefing (and see, here is an area where my language has changed working at APL. Formerly, I'd have said "give a slide presentation" or "give a talk."), the amateur points the wireless mouse at the screen, rather than at the computer with the receiver.

If you came here because you are thinking of making the move, you'll find my experiences and opinions here. I recently started a full-time gig at Johns Hopkins University Applied Physics Lab. They started to order a PC for me. I asked if I could have a Mac. I have a 17" MacBook Pro.

Here's the interesting experiences of another convert. He's a well-known "Windows Expert." See A Windows expert opts for a Mac life.

Surely you've seen at least one of the "I'm a Mac and I'm a PC" ads. Well, this photo just hit my funny bone: .

• Just because someone is a Christian, doesn't mean he won't sometimes or often act like a jerk.
• That goes double for me.
