**Let’s use IntelliJ as a game engine, just because we can**

Ever wondered what would happen if you used IntelliJ IDEA as a game engine? Probably not, but Alexander did, and it turns out, it’s absurd and a lot of fun! Join Alexander for a lighthearted yet insightful dive into the absurdness of using one of the most sophisticated IDEs to create games within your codebase because... well, why not?

In this talk, Alexander will walk you through his adventure of using the IntelliJ plugin platform to implement game logic, render graphics, and more. He’ll share the head-scratching moments, the "aha!" breakthroughs, and the plain stupidity of making this idea work. You'll see IntelliJ handling sprites, game physics, and maybe even a rogue mutable variable trying to destroy your cursor!

This session is for anyone who believes that the best projects are born from a spark of curiosity and a sense of fun. Discover how pushing the boundaries of your tools can lead to unexpected innovations and a lot of laughs along the way. After all, the most important work we do is often the work we find the most fun. Come ready to chuckle, learn, and maybe even be inspired to try your own offbeat experiments!

**Cracking the Code: AI Hallucinations and Live Hacking**

Is your organization ready to transform your coding practices with generative AI tools such as Copilot, ChatGPT, or Code Whisperer? Do you know how to use these tools to boost your development speed without sacrificing security? Join this session to explore the potential and pitfalls of generative AI in coding.

In this interactive session, we will discuss the risks associated with generative AI, including hallucinations and security vulnerabilities. We’ll demonstrate live coding of an application using Copilot and ChatGPT, followed by a live hacking session to expose the weaknesses in the generated code. Watch as we uncover issues like SQL injections, cross-site scripting, and directory traversal in real-time.

Join us to discover how to balance speed and security in your projects and learn how to safely use GenAI's power to enhance your coding efficiency while minimizing risks.

**Speakers**

**Alexander Chatzizacharias**

Alexander, a 34-year-old Software Engineer at JDriven, holds dual Dutch and Greek nationality. He earned his master’s degree in Game Studies from the University of Amsterdam, where he discovered his passion for gamification and software engineering. Alexander aims to bridge the gap between game development and software engineering, believing that both industries have much to learn from each other. He is dedicated to integrating technologies and methodologies from both fields. Additionally, he enjoys experimenting with new technologies and cutting-edge sdk's.

**Brian Vermeer**

Staff Developer Advocate for Snyk, Java Champion, and Software Engineer with over a decade of hands-on experience in creating and maintaining software. He is passionate about Java, (Pure) Functional Programming and Cybersecurity. Brian is a JUG leader for the Virtual JUG and the NLJUG. He also co-leads the DevSecCon community and is a community manager for Foojay. He is a regular international speaker on mostly Java-related conferences like JavaOne, Devnexus, Devoxx, Jfokus, JavaZone and many more. Besides all that, Brian is a military reserve for the Royal Netherlands Air Force and a Taekwondo Master / Teacher.
