Kotlin¹, Kotlin² and Kotlin³

Obviously, my current hype topic at conferences, meetups and whenever I meet other developers is Kotlin. Don’t worry, I do something else now and then. 🙂

Let’s start with Kotlin¹. Initiated by GDG Karlsruhe I gave a talk at the Karlsruher Entwicklertag 2018 with the title “Kotlin for Android-Developers”. As the title already says, it was all about Kotlin and how to use it in Android. For this talk I’ve created a new live demo and it was really worth the effort. Thanks to the dedicated audience and their questions, it was a mixture of a few slides, an extensive live demo and a vivid discussion. All in all, a great conference with exciting talks and interesting discussions during the breaks. Thanks to everyone who made this conference possible.

Just a few days later I spoke about Kotlin² again. It was really fun in the square. The topic was Spring Boot 2 and Kotlin, something I’m not that familiar with. Fortunately, I was only the insignificant sidekick for my dear co-worker and backend expert Hendrik. So I contributed some knowledge as Kotlin “expert” (think of even more quotes here) while Hendrik did most of the work at our live demo. The topic was interesting and I took the opportunity to take another look at Spring Boot 2. And above all, we had a lot of fun in the live demo and afterwards.

Last but not least I just couldn’t stop talking about Kotlin³. Therefore, it was really handy that I participated in the current episode of the “What’s happening?” podcast from inovex. In this podcast we talked (in German) about language features, interoperability with Java, some practical advice and how to use Kotlin in your Android app. Thanks to the two hosts Lukas and Christian for their work and this interesting opportunity. Another big thanks to the other guest Chris, who raised many important points in the podcast. It’s always a pleasure to work together or talk about stuff with these guys.

GDG DevFest Karlsruhe 2017

Although I worked on interesting topics at work and in private, posts on my blog are still rare. However, once a year there’s a good reason to write a post: As in the previous years, I attended at the GDG DevFest Karlsruhe. The conference was great again and I had the opportunity to give a talk. My topic was “Kotlin for Android-Developer”, which is an amazing programming language I’ve use for some time in different projects.

In addition to a few slides in German, my talk consisted mainly of a live demo. I’ve uploaded the demo code on Github. This code is certainly less useful without my explanations, but some participants asked me about it. So, have fun with Kotlin and if you’re interested in a Kotlin Meetup in Karlsruhe: There’s a Kotlin User Group with great talks, discussions and exchange of ideas.

GDG DevFest Karlsruhe 2016

Another amazing GDG DevFest Karlsruhe is over. The DevFest was, as in the previous years, a really great conference. So many interesting talks and curious visitors.

I also contributed to the conference: In my talk I spoke about my experiences in the development of a modern Android app. The talks was held in German and if you’re interested in the slides, I’ve uploaded them here.
