If I understand you correctly, the contract checking would just be "is this a
float?" which I imagine wouldn't re

Dear Sawfish and Racket users,
After roughly estimating the effort required to port Sawfish to Racket (
http://sawfish.wikia.com/wiki/Porting_Sawfish_to_Racket ), I found that it
would be too much work and would probably not be the best option. The
effort required before having anything usable wou
I could imagine a reason #5: you are porting programs from a language that
supports 80bits.

Ok. I have a number of minor this-and-thats for base-env.rkt that I've
queued up. I'll add this. Patch in a couple of days.
Thanks,

I think that paths were added to to the Racket grammar since the Typed
Racket definition was written, and the latter just needs an update.

I came across this: "Topsl: a domain-specific language for on-line surveys"
http://topsl.sourceforge.net/ it appears to have been a library / planet package
for Racket, its older though. Does anyone know if there has been further work
done on it, or a related project?
Thanks,

If there is any simpler way to have native 80-bit
floating point in Racket (say Racket->ASM compilation,
Racket->C, LLVM, anything), please do tell me.
Here's another razor/brick-related question: Wha

Yes, that's what I did.
The code is here:

The commented main is the single-sync version, which does not work as
intended (i.e., clients can get blocked when several clients are
connected), and the uncommented main is with threads, which
I'm not sure I understand your question.
But you need to wrap your input events with handle-evt or wrap-evt so
you can close over state that helps you distinguish the events when sync
returns.

A) I know draw.ss is deprecated -- this is legacy code

To make it work and avoid one of the clients to be blocked half of the

I just pushed a fix for this to the git repo. Thanks for the report.

Although I don't know the answer, I wanted to suggest using Amazon EC2
as a way you could determine this for your specific application.
You could provision two instances, use them for a few hours, then
suspend or delete them. Even with the largest instance types it would
probably cost ~$15 for say
If you're calling from Racket to TR then you have the contract
checking and probably the floats flowing thru there need boxing.
Can you put the loop itself into TR?
