Episode 4 of the 2026 Edition - 15 years of fun with Kotlin
Thu, Jul 16, 4:30 PMIn July 2011, Kotlin was unveiled to the public as an open-source project by JetBrains — [first announced](https://blog.jetbrains.com/kotlin/2011/07/hello-world-2/) on July 19, 2011. A few years later, on February 15, 2016, [Kotlin 1.0 was released](https://blog.jetbrains.com/kotlin/2016/02/kotlin-1-0-released-pragmatic-language-for-jvm-and-android/). And of course let's not forget the [annoucement by Google ](https://developer.android.com/kotlin/first?hl=en)that Kotlin became an offically supported language in 2019. Also our little group was founded in 2016. So we have a lot to celebrate: 15 years of Kotlin, 10 years of the 1.0 release, 7 years of Kotlin on Android, and 10 years of KUG Berlin. Join us at JetBrains HQ in Berlin and let's celebrate with `fun` ! **⚠️⚠️ Seats are limited — please register only if you plan to attend, and cancel early if you can't make it.** **Line-Up:** 👉 **Docs & DSLs: OpenAPI in Kotlin** For the past decade, OpenAPI has emerged as the de facto standard used for documenting HTTP servers. As its popularity has grown, back end frameworks have adopted some sophisticated integrations, allowing client code to be generated directly from a running server. This talk will introduce you to OpenAPI tooling in Kotlin and how we were able to provide first-class support in Ktor. *by Bruce Hamilton* 👉 **15 years of fun** *by Maia Grotepass & the community* **Speaker Bios:** **🗣** **Maia Grotepass** Mobile dev since Cupcake. Android GDE. Kotlin enthusiast. Dogs make me happy. **🗣** **Bruce Hamilton** I've been a full-stack engineer for over 15 years now, working in Java, Javascript, and Kotlin. Currently, I'm working on Ktor, an open-source networking library and framework. More generally, I'm trying to elevate Kotlin to be the best server-side programming language in the industry!
