You're reading the public-facing archive of the Category Theory Zulip server.
To join the server you need an invite. Anybody can get an invite by contacting Matteo Capucci at name dot surname at gmail dot com.
For all things related to this archive refer to the same person.
There's a new forum for talking about category theory and programming, called The Monoidal Cafe. It's on Discord. It was set up by Zanzi. It has a much more free-wheeling vibe than here.
@John Baez Speaking as one on Discord but unable to use the link above to get access, it seems that particular link doesn't suffice. I tried searching on discoverable communities as well, but it does not appear. I think you might have to provide contact information for one who can dispense invites, so that people can inquire (if it is to remain non-public).
The invite link for a discord server can be found by right clicking on the server, choosing "Invite People". There should be an invite url in the windo that pops up after. This link will only last for seven days.
Since I'm not a really active member of The Monoidal Cafe I don't feel morally empowered to go around giving invite links... I don't know what their attitude is about this.
Given the recent spate of spam, I think Zanzi's going to want to be selective. But you can find her on Mastodon and Twitter.
@Zanzi is here. Or maybe @Zanzi is the right user to ping?
I think she logs in here extremely rarely, but I can forward messages by walking to the other side of our flat
nods in TCP/IP physical layer abstraction
So yeah, one way you can get an invite is to dm me on here
Thank you for the plug @John Baez!
Yes, we're a server for the Programming Language perspective on Applied Category Theory :D We're pretty relaxed there, and a bunch of people from here are there already, so feel free to join - we're open to everyone, not just coders.
(I'm especially interested to see more Algebraic Julia people there, as we've got some ideas for a type system for hypergraph categories that could lead to a nice port of the AJ machinery from Julia to Idris/Agda)
I'm going to share a temporary invite link to the community, and if that runs out feel free to ping me or Jules: https://discord.gg/apZFum9t
