Yes. He then goes on to use the phrase in some very strange ways (and
often in quotation marks!) Perhaps over the years the term has been
misused so much that the original meaning has been lost. A good example
of this is "momentarily", which used to mean "very briefly", but now (in
American English) means "very soon".

Many good technical terms have been destroyed by deliberate marketing
obfuscation. A "megabyte" used to be 2^20 (1,048,576) bytes, but then
the hard disk marketers decided that their disks would look bigger if
they started calling 1,000,000 bytes a "megabyte". Maybe marketing has
been playing around with "binary compatibility" too.

So to give Shuttleworth the benefit of the doubt, maybe he is using
"binary compatibility" in this almost meaningless way because he feels
that's what his audience will best understand.

We are agreed on the dangers of using Debian (or Red hat, or SuSE, or
Centros, or...) packages on Ubuntu. All we are arguing about is whether
"binary compatibility" is the right term. I think the right term here is
just "compatibility".

Shrug. The main thing is that people don't go using Debian packages on
Ubuntu unless they are ready for surprises.

Just out of interest, what do you think the correct term is for the
situation where the same executable can be run on two different
platforms? Off-list if you like.
