Fixed that pesky #kotlin #coroutines #concurrency bug by… running everything synchronously!

Concurrency is hard, let's go shopping…

Can you recommend any general learning resources on coroutines?

I'm looking for tutorials, books, or other non-video sources that are largely language independent (or introduce a few primitives clearly) and, most importantly, explain how to program with couroutines and for which problems or situations they're typically used. I'm looking to learn the concepts, not features of specific languages.

I'm not interested in other control or concurrency primitives.

Today I need to understand #Python coroutines and futures. The documentation doesn't explain it at all well to me.
I'm very comfortable using async/await in JavaScript.
Does anyone have any pointers?

Earlier today I released a new version of https://thi.ng/fibers aka building blocks and operators for coroutine-based multitasking and alternative to async-await. It's one of the more recent packages, but also one which is quickly cementing itself as one of the most powerful & flexible tools of the whole #ThingUmbrella collection, similar to how https://thi.ng/transducers & https://thi.ng/rstream have done in other contexts...

Recent versions have included new helpers to improve interop between fibers and async functions and to simplify time-sliced processing of child tasks and/or iterables (incl. via transducers).

The attached code snippet shows an example excerpt of how this is used in the recent (and even more recently updated) #HowToThing Mastodon UI demo. See linked toot for demo link & fully commented source code...

Can a Swift async method return multiple results over time? Different types, so I don’t think I can use AsyncSequence? Something like (pseudocode)

let (showProgress: async Bool, result: async MyThing) = await doSomethingLengthy()
if await showProgress {
showProgressScreen()
}
processResult(await result)

?

doSomethingLengthy() would guarantee that doProgress is fulfilled before result, in case that helps.

Or must it be a 2-method delegate?

After some friendly inquiry by @computersandblues, I spent a few hours today adding basic CSP (#CommunicatingSequentialProcesses) primitives for https://thi.ng/fibers and writing some preliminary documentation. I'm amazed how simple (and easy!) it was this time around (compared to https://thi.ng/csp) and it's giving me big hopes for the fiber based approach in general...

🧵 #AGBIC Day 1

After prototyping a decent Othello AI, I'm trying to decide how to represent the Othello board in PICO-8.

• 2D array
  pros: intuitive
  cons: slow to use

• bitboard
  pros: uses bitops on 64-bit nums (fast!)
  cons: PICO-8 doesn't have 64-bit nums; will have to adapt
