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 😄

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 🥳

@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: github.com/arrow-kt/arrow/is…

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.

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

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)

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