The site is back up!

Hey everyone, the Rock the JVM site has been down today because of some SSL certificate migration that caused issues on the course platform. Rock the JVM runs on Teachable, which ran into an SSL snafu today. This downtime was unannounced, poorly communicated and poorly handled. Some people aren't sleeping tonight. Happy to offer extensions to anyone on memberships, while the problem is being resolved. DM Daniel Ciocîrlan for any questions or requests. Big sorry, and thanks for the patience 🙏

New video! How to build full-stack #Scala applications with ZIO and Laminar - a walkthrough of a Scala app that contains: - a layered backend w/ ZIO, Tapir & Quill - a reactive frontend - shared data & definitions - a TypeScript library integration - Metals dev setup with examples of good practice. The app is a template by Olivier Nouguier after his experience with the giant ZIO Rite of Passage course on Rock the JVM 🤘 https://lnkd.in/dtf278Xn

New video! Testing Functional #Kotlin with the Arrow library and the Raise DSL - learn how to use - JUnit - AssertJ - Kotest - mockK - Mockito in combination with Raise, Either and more: https://lnkd.in/dQbKV78Z

New long-form article! Raise your Tests: a guide on how to properly test your functional #Kotlin code written with the Arrow library and the Raise DSL: https://lnkd.in/dRqPYRWG by Riccardo Cardin 🈺

How should a Scala developer react when they hear another Scala developer say "for loop"? 🚶 leave 🙄 roll eyes 🔫 do the Pulp Fiction "say that again, I double dare you" scene 👩💻 write a monad tutorial 😇 direct them to Rock the JVM

What you make with code matters way more than the language & tools you use to build it. That said, pick tools which get out of your way. It should be easy to put your thoughts in code, and once you write it, you should know it works. #Scala is great for that.

New video! Automatic dependency injection in pure #Scala, with no frameworks or libraries, just with the type system and 50 lines of code: You'll learn - where DI is useful - how the ZIO library does it - how we can do (almost) the same without effects or layers Technique by Martin Odersky (GitHub link in the comments) after an informal discussion, with a bit of twist at the end. Please enjoy! https://lnkd.in/eyyMJDbC

Take all the time you need to pick a great general-purpose tool, and then stick with it. #Scala is an amazing choice.
