JVMTI: Introduction and use cases for the JVM Tool Interface
Ever wondered how profilers track memory allocations or how they can measure the methods that use most of the CPU resources without knowing your code?

Meet JVMTI — the Java Virtual Machine Tool Interface, that allows tracking, inspection and modification of JVM applications. Track the states of your threads, trace objects as they follow the flow of your application or modify instance values at runtime. Learn how JVMTI works, how profilers, debuggers and other tools rely on it and find interesting ways to solve issues of your application. Lastly, see how security researchers monitor JVM applications to help protect users and organizations.

Fun with Flags: Bringing the Fun Back into Feature Flagging with OpenFeature
Feature flags have revolutionized the software delivery lifecycle, enabling teams to decouple releases from deployments and create a more agile development process. They're often hailed as one of the key practices in modern software development—at least in theory.

However, as systems grow in complexity, so do the challenges associated with feature flagging. From supporting multiple languages and managing targeted evaluations to avoiding vendor lock-in and safely decommissioning obsolete code, what initially seems like a straightforward problem can quickly become daunting.

The OpenFeature community is tackling these challenges head-on by providing vendor-agnostic SDKs and a suite of powerful tools designed to simplify the feature flagging experience. Join me as we explore the common pitfalls of feature flagging and discover how OpenFeature can help bring the fun back into this critical aspect of software development.
