🇬🇧 Be more productive with IntelliJ IDEA by Marit van Dijk (JetBrains)
IntelliJ IDEA is designed to help developers stay in the flow while working. It has a powerful editor, refactorings, navigation, and all kinds of smart features to help you write and read code. At the same time, it is jam packed with tools professional developers need, like Maven, Gradle, Spring, Git, Databases, Test tools and more. And did I mention a fantastic debugger?

In this talk, you will see how IntelliJ IDEA supports your workflow without having to leave the IDE, and learn how you can be a happier and more productive developer.

🇬🇧 Secure Java Applications against Quantum Threats by Ana-Maria Mihalceanu (Oracle)
While we all get excited imagining the many happy path scenarios using quantum computers, what if such computation power will be employed for compromising the cryptographic algorithms that secure data and communications?
While Y2Q or Q-Day feels distant, bad actors steal currently unreadable encrypted data with the expectation of being able to decrypt in the future.

Applications can resist classic and quantum attacks by looking into adopting asymmetric Key Encapsulation Mechanism (KEM), key derivation function (KDF), and authenticated encryption with additional data (AEAD) encryption. This talk covers the connection between these concepts, their implementation in the JDK security and demonstrates how can these be integrated to achieve secure quantum-resistant messaging in Java.

By the end of this talk you will understand how to take advantage of JDK security and toolchain capabilities (keytool, jfr) to fortify your application and withstand the quantum-era threats.
