01:04 <spdegabrielle> I think the channel description for #racket could be updated

01:04 <spdegabrielle> It doesn’t seem accurate to say this is the right place to ask questions about DrRacket

01:05 <spdegabrielle> It’s not a bad place. Asking questions here is fine. But the discourse and discord are probably better options

01:05 <spdegabrielle> [Discourse](https://racket.discourse.group/invites/VxkBcXY7yL) and [Discord](https://discord.gg/6Zq8sH5)

01:31 <bremner> I wish we could promote free solutions over discord.

01:31 <bremner> free as in free software.

02:23 <dataangel> now that racket runs on top of chez can threads use multiple cores or do you still have to use places for that?

06:09 <dzoe> dataangel: (thread ...) is a green thread and generally they do not run in parallel

06:10 <dzoe> dataangel: however with CS the futures can be used for parallelizing most of the work as now the GC is _not_ future-unsafe operation.

06:11 <dzoe> bremner: my sentiments exactly - the problem is, that most people just migrated over there and if you want to reach them, your options are pretty limited now :-/

09:00 <spdegabrielle> bremner: me too. Discourse is free. GPL2 https://www.discourse.org/about

09:02 <spdegabrielle> And it has chat

10:49 <bremner> spdegabrielle: ack

10:57 <spdegabrielle> dataangel: i don’t know the answer to your question. From the manual https://docs.racket-lang.org/guide/parallelism.html

10:58 <spdegabrielle> “Racket also provides threads for concurrency, but threads do not provide parallelism; see Concurrency and Synchronization for more information.”

11:29 <bremner> dataangel: there was some related discussion in (I think) the state of racket panel at racketcon. Dunno if transcripts are available but the videos are.

12:30 <spdegabrielle> If you click chapters you can see the transcription - but I’ve not worked out a way to search

12:36 <bremner> nice

13:19 <Tuplanolla> I'm reading the documentation of `->i` and `unconstrained-domain->`, and trying to piece together a way to represent a contract for a procedure that can take `(-> integer? boolean?)`, `(-> integer? integer? boolean?)` and so on up to `(-> integer? ... boolean?)` as a parameter, but cannot figure it out.

13:20 <Tuplanolla> Using just the form with ellipses requires always passing in a procedure that can take an arbitrary number of parameters.

13:26 <dataangel> dzoe: but does that allow shared memory multithreading with multiple cores?

13:29 <dataangel> dzoe: or is this later work will enable this sort of situation?

14:30 <dzoe> dataangel: https://trustica.cz/en/blog/2019/10/10/parallel-merge-sort-leveraging-futures-in-racket/ - does this answer your question?

14:32 <dzoe> I can finally point to my old blog post and it's (hopefully) useful ;-)

21:51 <dataangel> dzoe: sort of, it depends on whether futures-sort uses places ;)

21:52 <dataangel> separately, is typed racket still actively developed? I played with it in ~2018 and really liked it but I'm curious if I try it again if anything will actually be different
