We are delighted that the Prachtsaal collective is hosting us!

Line-Up:

👉 Agentic AI in Kotlin
by Kazik Pogoda
The number of AI tools in Kotlin ecosystem is very limited and the knowledge of writing autonomous AI agents in this environment is relatively scarce. I decided to actively fill this gap, by developing the whole set of Kotlin multiplatform AI libraries under my Xemantic brand, most notably anthropic-sdk-kotlin and claudine AI agent. If you are interested in adding AI based autonomous reasoning to your Kotlin code, this presentation is for you, as I will present live-coded examples.

👉 A walk in the Lindenmayer fractal forests with a Kotlin notebook
by Maia Grotepass
Some pieces of Kotlin code are better discovered through exploration. Code for a Lindenmayer system (Lsystem) is an example of this. These systems can generate beautiful organic looking fractal structures. A few small tweaks cause unexpected variety: perfect for experimentation. Kotlin Notebooks are especially suited for experimental and exploratory coding. This talk will showcase the use of Kotlin Notebooks to draw a series of Lsystem trees. It will be a live code session in IntelliJ with a shareable Kotlin Notebook as a result. You do not need to be a data scientist to enjoy this talk. The audience will: - See Kotlin Notebooks in action with the focus on reusable canvas drawing - See an iterative coding workflow that explores code and visuals - Learn about Lindenmayer systems - Receive a link to the talk Notebook which they can copy and modify to continue the experiments in their own time.

👉 Of Cocktails and Mocktails.
by Frank Tamre
In this talk, we delve into the nuances of leading a diverse team and look at the cultural challenges and opportunities that exist while leading a multicultural team.

Drawing experience from having led a multi-cultural team of engineers with different seniority levels I will cover effective communication strategies, the importance of cultural sensitivity, and how to leverage cultural diversity to enhance teams.

🗣 Maia Grotepass

I have been a mobile engineer since 2009. My first computer was a ZX81 and there was no Internet. Fast forward: I am still passionate about learning and working with code, computers and people to build and explore new things. For the past decade Android and its ever evolving framework, libraries and community have been my passion. I love Kotlin. My dog is my best friend. I dance and do yoga to counter my sedentary lifestyle.
