Hi.
I have been here a year or so, and trust you will forgive my posting
pseudonymously on this occasion. If you guess who it is, please be kind
enough not to say for now.
A friend has been invited to be a consultant for an investment bank that
would like to build a set of analytics for fixed income products. The
team is currently quite small - about 5 C++ developers - and the idea is
to start with a proof of concept and then build on it as there is
further buy-in from the business.
Having been using D for a year or so, I am pretty comfortable that it
can do the job, and likely much better than the C++ route for all the
normal reasons. I haven't experience of using D in a proper enterprise
environment, but I think this group might be open to trying D and that I
might be at least part-time involved.
I also have little experience in getting across the merits of this
technology to people very used to C++, and so I have not yet built up a
standard set of answers to the normal objections to 'buying' that will
crop up in any situation of this sort.
So I am interested in:
- what are the things to emphasize in building the case for trying D?
the most effective factors that persuade people are not identical with
the technically strongest reasons, because often one needs to see it
before one gets it.
- what are the likely pitfalls in the early days?
- what are potential factors that might make D a bad choice in this
scenario? I would like to use D certainly - but it is of course much
more important that the client gets the best result, however it is done.
- am I right in thinking C++ integration more or less works, except
instantiating C++ templates from D? what are the gotchas?
(I appreciate there is not so much to go on, and much depends on
specific factors). But any quick thoughts and experiences would be very
welcome.
Just a thought, try getting them to use D for prototyping. Worse case
they will play around with D before settling on e.g. c++. Best case
scenario they'll move it into production.
