:You've done the same thing in this email that you did in your earlier
:comparison. You've found a trivial subset of the problem and then make
:the generalization that solving that subset shows that the solution to
:the problem is trivial.
You know as well as I do that embedded projects are ALWAYS a trivial
subset of something. Until you get to the level of sophistication of
an iPhone. You only need to solve the subset of the problem that
the embedded project covers.
Most general problem sets become trivialized when used in degenerate
environments. This is not a description of a trivialized solution to the
problem set being generalized up, it is a description of the generalized
solution to the problem set being applied to a degenerate application
which trivializes many aspects of the general solution.
My interest is in large scale systems, OF COURSE I'm approaching the
problem from the point of view of large scale systems and not small
scale systems. Don't be silly.
