Historically, debuggers are used to help locate and fix bugs. Nowadays, the debugger in IntelliJ IDEA can help you do much more than that. Let's see how the debugger helps make the development process more productive. I demo various features for debugging Java applications, including not-so-standard ones, like:

* Lambda breakpoints

* Stream chain tracing

* Dropping the frame

* Emulated method breakpoint

* Evaluate and log

* Non-suspending breakpoints

* Custom data renderers and more

Anton Arhipov – Building AI Agents in Kotlin

AI agents are fully autonomous programs whose actions are dynamically directed by LLMs. In agents, LLMs are not only used for standalone tasks while keeping the general flow predefined in the code – they become the main actor responsible for answering how a task should be accomplished. This talk will provide an overview of AI agents, including their building blocks and basic workflows.

Viktor Gamov – Introduction to Stateful Stream Processing with Apache Flink

Stream Processing has evolved quickly in a short time: only a few years ago, it was mostly simple real-time aggregations with limited throughput and consistency. Today, many stream processing applications have sophisticated business logic, strict correctness guarantees, high performance, low latency, and maintain terabytes of state without databases. Stream processing frameworks also abstract a lot of the low-level details away, such as routing the data streams, taking care of concurrent executions, and handling various failure scenarios while ensuring correctness.
