I’m a Swede and a programming hobbyist. I love Racket and as of now I’m making
a space shooter with Pict3D.
Had to make a Quaternion module to make flying around possible. I know Racket
is thought in Linköpings Universitet here in Sweden, might be good place for a
meeting.

Why do one have to use define/override to get the mouse working on a canvas?
Why not just call the method? It’s a little bit confusing.

Okay, that explains it. I've made a parallel map function but since I can't
pass procedures it had to be quoted lambdas, but that works well.

Every time I se "optimisation" I get happy. The only thing I miss is being able

Strangely I can't get the example working from the docs and serial lambda isn't
a cakewalk ether. So if you got a working example please share it!

The function sends the lambda to a place, and places don't accept procedures,
so a quoted lambda is the only option.

I have function that demand a quoted lambda as an argument, how would you write

I've made a package with two map implementations that use parallelism. "pmapf"
use futures and "pmapp" use places, I would like to get some feedback and

You can install it through the DrRacket package manager.

I've done implementations with both and start to wonder where futures excel
over map and places. Ive done two map implementations using futures and places.
In heavy computations places is unquestionably the best, map and futures has
small difference. In lighter computation places aren't worth ta
Thank you! That works great! Now I'll try updating my package for racket, hope

If there was packages for the major dists like fedora, ubuntu and suse on the
racket homepage it would be easier for people to get. It would help racket
becoming a little more known and used.

I really like Racket although I haven't used it much. It's a shame it isn't
more popular, maby a new slogan would make it better. I don't think "A
programmable programming language" is very catchy, "Batteries included" might
be a better option.
I'm planing to make a CAD in Racket, I have done
