Hello. I am exploring some physics ideas and I was thinking about making some
3D simulations to flesh out some of my ideas and to demonstrate them to others.
Are there any polished packages for doing 3d stuff in racket? I looked just
briefly a while back and didn’t have much luck. I think I foun
Awesome. Also I didn’t know you could include ‘#%place like that.

Mine was working fine until i turned system integrity protection back on,

Great, thanks for all of that digging. Ya, i think i will go the
non-declare_modules, non-ctool route for now as i think this fits my
use-case pretty well. I want to allow access to the full racket library for
racket code that changes often.

Do generators and typed racket work together well? It seems (yield) doesn't
have a type and i couldn't get my module to work.
Is there a way to make some procedure untyped in the middle of a typed
file? Is it just best to break these things into separate files?
Thank you

Actually, is there any way at all to use lazy lists of things (streams or

Also can you think of a better way to do this than my implementation of
iterate? The use case is putting it in a for loop along with a break or a
finite list.

Hello. Ran into some problems with typed racket and define-cstruct when

I looked into it, it seems to be implemented in `src/cs/rumble/foreign.ss`
using chez get-thread-id, comparing it to 0 and using a stored ref to the
original async callback queue, so looks like this is not exposed to the
user. Hm.

Note this is from a return value of racket_apply; i called a racket
function from c code and want to store the cptr it has returned.

I have a temporary workaround where i have created an ffi function
racket-side to call into c, so that i can automatically use the _cptr's
racket-to-c function. I wonder if there is a way to manually extract the c
value for the case where i want it in a return value of racket_apply.
Nate
O
Then you can use `Sunsigned_value()` to convert that field value to a
pointer-sized integer, then case.
I might have some part of that wrong, but it should be close... Of
course, there should be better support for record-field access and
cpointer extraction, so I'll add to the API.

I have one place that has a very simple module and one place with a more
complicated module. Is there some sequence that i should do things in for
the minimal startup time? It seems nothing i do really helps much.
