**Don‘t let the AI hype break your mentality**
The topic of “AI“ seems to be everywhere these days, especially for software developers. From claiming to be the problem solver for day to day tasks up to apocalyptic scenarios of replacing all jobs, the stories being told vary wildly.

Either you get caught by it and your thoughts just spin around how to be an early adopter, create a new service out of it, and see lots and lots of possibilities (often by ignoring real world needs and losing a rational base on decision making),

Or you get anxious about what AI could mean to your current role and your future career prospects. The media draws a picture of the world in which developers are forced to use AI to create new software, becoming a prompt operator and ultimately losing their job to the same AI.

But this fear of new overt-hyped technology taking away our jobs is not new. In the past many hypes appeared, some of them just vanished, some changed the way we live, communicate, consume media or travel. They can change the world, and so can we.

In my talk I want to walk through some generic approaching to handling a hype, how hypes affects our daily work, and what impact hypes may have on our mental stability.

**About Markus Wendland**
Markus is a seasoned software developer with 30 years of experience, starting as a curious script kiddie and growing into a tech expert. Having witnessed the rapid evolution of the industry, he now shares not only technical insights but also a crucial perspective on mental health in software development. Drawing from his own experiences navigating the highs and lows of a demanding career, Markus delivers honest, thought-provoking talks that encourage open conversations about well-being in tech. His mission is to help developers build not just better software, but also healthier, more sustainable careers.

**Level Up Your Java Streams with Gatherers**
Since Java 8, the Stream API has been a valuable tool for Java developers. However, our hunt for better solutions has often left us wanting more. Until now, we could only use the standard provided intermediate operations on streams, like map, filter, and flatMap.

Enter Java 24's new Stream Gatherers, which allow for adding custom intermediate operations to our streams.

In this session you'll learn what Gatherers are, where they shine, and how you can implement your own.
By the end of the session, you'll be fully equipped to use this powerful new feature in your day-to-day work.

**About Hinse ter Schuur**
Hinse is a Software Developer at SDB Professionals. Over the years he has done a lot of Java and Scala coding. He loves to share his experience by doing pair programming, reviews, writing articles and giving talks.
