Community Call — Sept 2, 2020

[Ported from the Discourse forum]

@expede:

The first open Witchcraft community call will be held on Sept 2, 2020 at 15:30 GMT (8:30 PST)

https://us02web.zoom.us/j/82052674953

Interested in a topic to discuss, please add it in a comment below. (The call itself will be informal, so more topics “at runtime” are also okay)

I’ll post the password just before the call to help cut down on Zoom bombing.

Okay, the meeting password should be “functor”, but I’m don’t see the option any more, so maybe it’s just open 😛

---

@QuinnWilton:

I missed the call, didn't I? I thought it was for today:

Sorry about that 😅

---

chouzar:

That is too bad 😔. I think the call will be uploaded somewhere. A couple of bulletpoints from what I remember:

A website to show off the library
“Where/How to start” guides
An excersism, katas like project as teaching tool
Help with issue tracking/maintenance
New abstractions/extensions (lenses)
Keep up doing video meetings

I’m probably missing some other important points 🤔

---

@QuinnWilton:

Thank you! This is very helpful. I’m looking forward to the recording, if it ends up getting posted.

@expede:

Okay, video recording 👇

Also we didn’t take notes, but here was the outline that I was working from:

Welcome

• Go around, quick intro & why interested
• Why I’m looking for help
• Brief history of Quark, Witchcraft
• OpenCollective, Erlang Ecosystem Foundation

What’s Needed

• Bump Elixir version on whole suite
• Website
  • Example code
    • Real world use cases
    • Common patterns
  • Explainers
• TypeClass
  • Speed up compilation by moving checks to generating test funcs
• Answering questions in GH Issues
• (Several) open PRs — reviews and maybe some fixups

Future

• More type classes (e.g. profunctors, CRDTs), various recursion schemes
• Optics
• All of the data structures in Purely Functional Data Structures

Several folks also mentioned that some “how to get started” would be helpful. The current docs are pretty formal and theory-heavy. Some ‘hey have you considered a semigroup or Either?” would be useful. Also perhaps some kata/exercisms that people can write and check with tests.

@expede:

I also promised a few links that were mentioned through the call:

• Functors, Applicatives, And Monads In Pictures link
• Haskell from First Principles homepage
• Algebra Driven Design link
• Purely Functional Data Structures PDF / hard copy

---

chouzar:

Okay, video recording 👇

It asks for a passcode and it is neither “functor” nor “empty” 😁

---

@expede:

Ah, that’s the nonsharable (host) link. Let’s try that again!

[Many hours later]

Well, since the video is so long I had to verify my account with YouTube. It also failed to upload a few times, but I think I have the flow down now 😅 👍

Let me know if that’s not visible for some reason

Oh, also forgot this link earlier that I believe was shared by @chouzar https://atypeofprogramming.com/

ordepdev:

Oh, don’t know why, but I kept telling myself that the call was scheduled for the 3rd; sorry about that and thanks for the upload, will watch as soon as I can!
