Given the announce of PowerLinux, you might actually hear us start to use this acronym more frequently as a reference to the IBM PowerLinux program. This is an unofficial, not sanctioned by the Big Blue Zoo, use of an acronym. But, it indeed is one worthy of tucking into your Rosetta Stone should you meet one of us on the street and we slip up.
I would like to point out, that this acronym does have an official use inside IBM for Initial Program Load which basically means "booting" as in "starting". Those of you with AS/400 or mainframe heritage, will recognize that term. Detailed reading on the topic can be found in the IBM Power System Information Center.
If you have heard an acronym and want us to explain, feel free to let us know.
