The inventor pronounces it 'Jiff' (Score 1)

I attended a Caldera OpenLinux (hiss, boo) 2.0 demo years ago. The speaker relayed an anecdote from when he was at a seminar, and some guy in the back pronounced it "jiff" - which the speaker 'corrected' as a hard 'g'. The guy in the back responded "well, I invented the format, and I pronounce it 'jiff'."
