A new month, a new version of #YAES 🥳 Version 0.8.0 finally introduces the `YaesApp`. Now, you can develop your direct style #Scala app, and Yaes will take care of the execution of most of the effects 🙌
Plus, we redesigned Channels and added overflow policies! 💪

#Scala Effects lovers, here is the Halloween 🎃 release of #YAES. We introduced Channels in the library. Now, fibers can communicate asynchronously through message passing 📨. #Kotlin Channels heavily inspired the feature.

My first @scaladays.org just finished. Thanks to all the people who attended my talk and took some time to chat with me 🙏
There are a lot of engineers, data scientists, front-enders, and students who do extraordinary things using #Scala every day, and are the heart of our community 💕. Thank you all

Version 0.5.0 of the #YAES effect system is here 🚀 (just in time for @scaladays.org...fiuuu). We added the `State[S]` effect to the #Scala 3 party 🥳. However, be careful that the current version is not thread-safe.

#DropsOf #Java: Checked exceptions were a good idea ✨. They are some form of an effect system. You know precisely what kind of effects a function performs. To eliminate the effect, you need to handle it, and the compiler forces this behavior. However, they don't compose with lambdas 🤷♂️

#DropsOf #kotlin: Do you know you can implement the race primitive 🚗 for coroutines in just one line of code?
The `channelFlow` has its coroutineScope, and when the `first` function cancels the Flow execution, it cancels all the running coroutines that did not win the race. 😍

Hey, #Scala lovers! I'll give a talk at the next @scaladays.org 2025 🎉. I still can't believe it 🤪.
Let's meet in Losanna to share our experiences on direct-style and monadic effect systems! I'll bring my (on-going) knowledge about the former, with my library #YAES ⭐️
See you there 👋

Today, I talked at Ticino Software Craft 🧑🔬. We discussed #Scala Effect Systems, both monadic and direct-style (in detail, the #YAES effect system).
It was a pleasure to join the Ticino software community.

Yesterday I played with the #YAES library to understand what is missing to gain RT. Guess what 🤔? Maybe I managed to introduce some form of RT in a #Scala direct-style approach. I need you 🫵 to join the discussion:

I’ve been #coding for almost 20 years in the “traditional” way. 💻 Now, it's time to give AI a chance. I use it in its basic form, such as Copilot. Can someone point me to some resources to implement a more complex and effective workflow? 🙏
