Point taken.
So I've redesigned it somewhat, and now there are 2 calculation "modes":
- The normal mode is pretty much like Frink (probably the one you want),
which converts everything to base SI units. Conversion back to non base
units can be done afterwards.
- The "quoted" mode prevents a unit fr

The science collection predates Typed Racket - among many other things. It
is hand optimized using the fl- and fx- primitives, which were added before
Typed Racked, but this misses some optimizations that Typed Racket is able
to do. The biggest problem with the hand optimized code is that bugs tend
Dear All,
I need a data exchange format to serve as a simple database. There are
several choices out there. Do you have any suggestions on how to choose
between them?
Thanks,

If you want to commit to Racket, I think the most convenient choice
will be read/write and then serialize/deserialize, which are all in
the standard Racket distribution.

Thanks Jay. But is it human readable and editable?

Doug, I believe Dan is looking for algorithms for finding minima and maxima in
the sense of "Numerical Optimization" by Nocedal and Wright, and not compiler
transforms to improve performance. There is a pdf on the first page of hits on
google, so someone with time on their hands might want to go
a) You didn't mention this as a constraint.
b) read/write is a pure text format and is like Racket code. I
consider this human readable/editable.
c) serialize/deserialize is technically the same as read/write, but it
has many more invariants that makes it effectively not human
readable/editable.
I think I have a misunderstanding on the behavior of custodians. I'm trying
to write a Racket program that shuts down any subprocesses it may have
created when the program exits, regardless of whether the exit was graceful.
I would have thought that the root custodian would have taken care of this
