- Two anecdotes about the faddishness of OO at the moment.
-
- (1) I was approached by a graduate student who wanted to write a
- masters thesis. I should add that this student works for a very
- large government contractor on a very large project, an Ada one
- as it happens (not that it matters!).
-
- The student had a proposal in hand: "prove that OO is less efficient".
- The following (abridged) dialog ensued:
-
- MBF: Less efficient than what?
- Student: Than traditional methodologies
- MBF: Less efficient in what sense?
- Student: Slower and bigger executables
- MBF: You think you can prove that?
- Student: Well, that's what the folks at work say
- MBF: But how do _they_ know? Have they tried comparing apples
- to apples?
- Student: I don't know, but I don't think so. They are interested in
- seeing my results.
- MBF: How about if we re-write your proposal so that you are
- _investigating_, for some appropriately boiled-down piece
- of your project, the run-time behavior of that program
- developed in OO fashion but also by a traditional methodology?
- Student: Oh, you want me to do the thing in two different ways, then
- compare?
- MBF: Yup.
- Student: Hmmm....that's a good idea.
- MBF: Yup. You might even be surprised by the outcome.
-
- The second draft is a bit closer to an honest assessment.
-
- (2) I had occasion recently to visit some folks in one of the military
- services, starting to develop a non-hard-realtime system. They are
- in a frenzy to sort out whether to use OO or not, and whether to
- use Ada or break their backs to get a waiver for C or C++.
-
- They hired a _really_ big-name consultant (NOT a professor, Mark!)
- to teach them his OO methodology and take a first crack at a design
- for them. After collecting a very large fee, he walked away from the
- project, leaving behind what they say is an unworkable design.
- Conceivably we (I and another professor friend) will get involved
- helping them sort it all out. Might be fun.
-
- In this group, the battle over both OO and Ada is purely religious.
- Seemed to me to be pretty devoid of technical content. And no, I
- won't tell you what group it was. I was there, though. And other
- friends have told me that this is typical of the state of things
- right now. OO is defined in these circles as "I don't know much
- about it, but it's that stuff that C++ does and Ada doesn't."
- And nobody can say for sure whether it will "work", whether it will
- improve cost-effectiveness, and by how much. Same old handwaving.
-
- Just thought I'd jump in with my $0.02.
