"Congratulations! Your session Unlocking the Power of Arrow 2.0: A Comprehensive Guide has been accepted for #KotlinConf 2024!" 🥳

My KotlinConf streak is continuing, 5th one in a row! I'm looking forward so much to talking #kotlin & @arrow_kt again with everyone. 🥰

[Alexey Soshin 🇺🇦🇮🇱🇬🇧 @alexey_soshin]

Just finished working on a brand new chapter for the upcoming 3rd edition of my Kotlin Design Patterns book, focusing on the @arrow_kt library ��

This will be one of the longest chapters in the book, but I hope that readers will appreciate it 😄

[Juan Rada @JuanCamiloRada]

@vergauwen_simon @antonarhipov @arrow_kt Just watched your kotlin config presentation, well done such a massive improvements! I would love to see this same presentation https://t.co/Egkc0puNBQ after context reciever and all the improvement you folks had done.

[Simon Vergauwen @vergauwen_simon]

Really cool stuff by @riccardo_cardin 👏👏👏

If you like fluent assertions style using AssertJ while using @arrow_kt in #kotlin be sure to check this out!

Ready for 2.0 💪

[Riccardo Cardin @riccardo_cardin]

Version 0.2.0 of the assertj-arrow-core library is out! 🚀 Now, you can easily test the Raise<E>.() -> A functions 🤩

[Simon Vergauwen @vergauwen_simon]

Help @arrow_kt to help #kotlin while participating in #hacktoberfest!

We need to help and support the Kotlin team in whatever way we can 💪

Arrow is already building with K2, hopefully soon with DEV/EAP versions and experimental targets 🥳

[Alejandro Serrano @trupill]

Helping with this would be incredibly helpful to the project. The task is quite concrete: ensure that we can keep testing on -dev versions by minimizing the dependencies on some Gradle plug-ins.

[Λrrow @arrow_kt]

@arrow_kt wants to support #kotlin by building DEV & EAP versions, and producing/testing experimental targets like #wasm.

We need your help! There is 12 days left in #hacktoberfest, and 77 open issues so far towards this goal!

Check them out here: https://t.co/wtMvb8n9IZ

An improved transcript of my talk Arrow 2.0's Trajectory #kotlinconf, and slides are available on my blog. https://t.co/jQRkF8Qhpj

Had an absolute blast talking about @arrow_kt at @kotlinconf, and the amazing progress of the last 10 years of #functionalprogramming in #kotlin!

[Λrrow @arrow_kt]

Your cats have good taste, but we'd like to see video proof of their musical talents...We have high hopes.

[Karin-Aleksandra Monoid @paranoidmonoid]

I'm home and now my cats are actively examining the things that I've brought from Amsterdam. Top-1 was this guitar pick by @XebiaFunctional (it was stolen immediately)

[Garth Gilmour @GarthGilmour]

Context Receivers are great for @arrow_kt. Revolutionary for FP in Kotlin. The complexity of wrappers can be avoided. #kotlinconf

[Garth Gilmour @GarthGilmour]

Very detailed update by @vergauwen_simon. I need to update a lot of blog posts 😉🤔 #kotlinconf

[Λrrow @arrow_kt]
