As one might gather from my username, this is a word that I have a special relationship with. I grew up in a “dis-TRIB-yu-ted” household, and went along naively assuming that this was how the word was pronounced. Then I came to my present location of West Texas, where students heavily favor “DIST-rib-yu-ted.” I can sort of see why: I do say “dis-trib-YU-shun,” which has a different syllable accent pattern than “distributed” for me. But “DIS-trib-yu-ted” just sounds so…awkward to me.
One of the computing environments my department supports is known as “Distributed” so I hear the word a lot, and I’ve never heard anyone accenting the first syllable.
