Every day there is more and more activity around Kotlin, the community is growing and Jetbrains launches new initiatives to offer online resources, as well as offline events and talks in every corner of the world. And this autumn we couldn’t miss an opportunity to organize Kotlin Everywhere in Barcelona with Jetbrains, but about it later!
Jetbrains & Kotlin
First things first, what is JetBrains? I think everyone knows this company, but just in case, let me briefly tell you the main highlights about them: Jetbrains is a software development company whose tools are targeted towards software developers and project managers. As of 2019, the company has over 990 employees in its offices in Prague, Saint Petersburg, Moscow, Munich, Boston, Novosibirsk, Amsterdam, Foster City and Marlton, New Jersey. And in July 2011, JetBrains unveiled Project Kotlin, name comes from Kotlin Island, near St. Petersburg. Team decided to name it after an island just like Java was named after the Indonesian island of Java.
Kotlin gained popularity very fast and now has local communities in almost every city of the world, where Kotlin real-life activities are organized on a regular basis.
Also, Kotlin Community has a strong online presence:
- Kotlin Blog
- Kotlin website
- Kotlin Talks
- Kotlin Forum
- Issue Tracker
Kotlin Everywhere – Global Event Series
In May, at Google I/O, Jetbrains announced a big step: Android development will become increasingly Kotlin-first. It’s a language that many of you already love: over 50% of professional Android developers now use Kotlin, and it’s the fastest-growing language on GitHub. As part of this announcement, many new Jetpack APIs and features became offered first in Kotlin.
To help you dive deeper into Kotlin, Jetbrains also announced a new program they’re launching: Kotlin Everywhere – a series of community-driven events focussing on the potential of Kotlin on all platforms. They are aiming to help learn the essentials and best practices of using Kotlin everywhere, be it for Android, back-end, front-end and other platforms.

Speakers & Talks
Hadi Hariri – VP of Developer Advocacy at JetBrains came to Barcelona to give talks about:
1.”Kotlin on the server with Ktor”
Ktor is a web framework built from the ground up using Kotlin and coroutines. Amongst other things it allows for creating robust and performant HTTP server applications. In this talk Hadi took a look at Ktor, the ideas behind it, and how we can easily create applications and have these deployed to Google Cloud with very little effort.

2. Functional Programming in Kotlin
In this talk Hadi explained the basics of functional programming, where it fits in with the Object Orientation paradigm and how we can use functional programming in our every day work. He covered important concepts in functional programming such as: Lambdas, Higher Order Functions, Partial Functions, Monads and more, and see how we can apply these in a series of functional patterns to cut down our codebase and at the same time make sure we keep it maintainable.

How to introduce Kotlin in a java project while maintaining the spring performance and making the developers happy. Concept after concept transforming a java application into a hotline one and never looking back on java.”
