Frequently throughout a program I am working on, I would like to specify a
probabalistic choice between two (for the sake of simplicity) procedures
that might be applied at runtime.
at present, I have defined a function like so :
(: odds-on ((Any * -> Any) (Any * -> Any) Real -> (Any * -> Any
I'm trying to do a simple depth-first search of a tree in Racket,
ultimately returning a list of nodes up to the node I'm searching for. I
want to do this side-effect-free, if possible, and I'm running into a wall
with the approach I started on...
This is my current implementation:
---
[else (bld-lst (- remaining 1) (cons (new-emetype) lst))]))])
(bld-lst how-many '(
Thanks!

It would be very helpful to me to have an example of the "local" form for
defining an internal function in typed racket. I've read and re-read the
docs and can't seem to figure it out from the syntax definition.
Here's what i've been trying:

Is any one else having trouble opening the .dmg file that was just released?
I open the file (either for the binary, or the source) and get the error
message ""no mountable file system".
Just want to make sure something is screwy on my machine, not with the
distribution.
I'm on OSX 10.6.5, Intel

I'm looking to put some Racket wrappers around bits of the OpenCV C api, but
I'm having a hard getting started. I've looked through the ffi/unsafe
documentation several times, but something isn't clicking-- I think I need
to peer at some examples. If anyone has a good example or two of calling C

Hmm, thanks, I really appreciate the help. Obviously an oversight on my
part, but I'm targeting OSX and the built-in apple "iSight" or whatever they
iCall it. It looks like it's on the list for UVC. I'm pretty new to this
game, and have very little experience with language interop and device
drive
I'm wondering how much it would take to get frame-by-frame output from a
webcam using Racket. My desultory searching hasn't turned anything up, so
I'm hoping someone has a hint or two. This wouldn't involve any networking
or remote access, but I would like to be able to acquire a stream of frames
