Jack, are you a software person by training?
The reason I ask is something that was noticed where I work.
I have found that just about every hardware engineer at work will
list address 0 at the bottom of a picture. Almost every software
engineer puts address 0 at the top.
Just how general is this trend? Anyone observe the opposite? I'm
wondering if it is just the people I have talked too (mostly ex-CDC),
regional (almost the same for here), or more wide spread than that?
Email would be fine...I doubt there is much general interest in trivia
like this.
