Great answer to the question "Can someone explain to me what #Coroutines are?"

#Kotlin

From #ProjectReactor to Kotlin #Coroutines

https://blog.frankel.ch/reactor-to-coroutines/

#fromthearchives

I'm starting to write my first lines. For now it's just to make sure that #boost #asio works the way I think it does and that I can write my event loop the way I want to. So exciting! I can already tell that I will have a passionate love-hate relationship with the #cpp #coroutines.

#AGBIC Day 20

Because I'm using #coroutines everywhere, I decided to create a centralized system for them, instead of having like 4 systems that each work differently.

Now it'll be easier to run things like the #AI and the #dialog box at the same time. (Check out that box!) #pico8

#gamejam #gamedevelopment #gamedev #indiedev #programming

I made the simplest "dialog" system I could make in #pico8. This will be how the dark void talks to you. (Spinning orbs unrelated.)

Because it should run alongside the game, it's controlled by a coroutine. (I know, I'm overusing #coroutines, but it was easy to get this working!)

#lua #gamejam #gamedevelopment #indiedev #programming

Yes!

I added an #animation that moves the cursor to an arbitrary location. IMHO, this makes the #AI look way more natural.

I also refactored the AI #code to use #coroutines, just like my animation system. Once the calculations start taking longer than a frame, I'll need it.

#pico8 #lua #gamejam #gamedev #gamedevelopment #indiedev #programming

#AGBIC Day 9

I have a simple animation system using #Lua #coroutines in #pico8. Right now, I added animation pausing to this system, so I could avoid having #game logic in the animation #code. This refactor makes it feel a lot less hacky.

I propose #mastodon be renamed to #coroutines.

as a fan of oldskool dystopic/apoc fiction & drama TV (esp from the 60s to 80s, & UK/Euro) let me just say Meta's choice of the Threads name is terrible... & PTSD-inducing

as a decades-long programmer with plenty of scars from doing & seeing multi-threaded programming at scale, well, let me just say Meta's choice of the Threads name is also terrible... & PTSD inducing

#Meta

Processes, Threads, Coroutines in Various Programming Languages.

Apart from giving an overview of the topic, I compare the runtime thread count of three different codes in five languages.

A hello world application.

An app that makes three blocking HTTP GET requests.

And finally an async/coroutine/green thread solution for making those same HTTP GET requests.

I was surprised by some results. :)

When discussing concurrency and #coroutines with colleagues, I always come back to this splendid presentation: https://www.youtube.com/watch?v=MCs5OvhV9S4

Don't miss the webinar on Thursday #Kotlin!

As always there is too much I want to talk about😅 Composing different #arrowkt DSLs and #KotlinX #Coroutines to running #Kotlin JVM/Native
#JetBrains #Ktor on #Kubernetes with zero-downtime.

& be sure to bring all your questions! ☺️

I wrote the third part of my #blog post series: “Implementing Co, a Small Language With Coroutines #3: Adding #Coroutines”. https://abhinavsarkar.net/posts/implementing-co-3/

Yes I built that myself using many many dowels. The LEDs also run on custom software on an ESP8266 (NodeMCU firmware) using #coroutines. Yes that's a shibazi zuo (333mm variant)

It's happenning again, #QCoro has a new release 🎉 #cpp #qt #coroutines https://qcoro.dvratil.cz/news/2023/2023-01-31-qcoro-0.8.0-announcement/

#Kotlin #Coroutines keep getting better 😍 This 1.8 feature is 🔥

> The "was optimized out" feature optimizes variables when you use suspend functions. However, it is difficult to debug code with optimized variables because you don't see their values.

I wrote a blog post about implementing a small interpreted #programming language With #coroutines: https://abhinavsarkar.net/posts/implementing-co-1/

Any recommendations for a smooth introduction to #Kotlin #Coroutines? Tutorials, books, webinars? Anything?

@notimetoplay Well, implementing #coroutines in a #programming language is non-trivial, you can't just push all your local state on a single stack anymore. But I agree that they are very nice to have. See this article for one of the benefits: https://www.magicsplat.com/blog/coro-iterate/ . Coroutines are also great for event-based code that would otherwise become a maze of callbacks.

I have a Spring Boot 3 Webflux Kotlin Reactor app where all controller points are suspended functions. Assuming I cannot use AtomicInteger I have a singleton service keeping track of number of requests served. Do I need to protect increment and get via a Mutex? I think yes, but I am little confused over the single EventLoop model of Netty, they do use pool of worker threads , is everything thread safe in Webflux Netty world by design? #kotlin #java #spring #springboot #coroutines #askfediverse
