LJC Meet-up at Discover

Join us on November 11th London for this special London Java Community meetup in partnership with Discover that reimagines developer productivity, inspires developer to harness AI tools for smarter workflows and confront the hidden risks of AI in code.

How Quarkus makes your apps cheaper, greener, and happier

Quarkus makes both people and hardware more efficient. That’s cool, but how does it work? Usually, we expect to trade-off developer experience against runtime efficiency. In this session, Holly will dive into some of the technical underpinnings of Quarkus’s efficiency. She’ll give advice for those using or considering Quarkus - should you be doing reactive programming? Do native binaries run fastest? The talk includes some theory (what underpins Quarkus’s surprising throughput?) and also live demos (does Quarkus really start faster than a light bulb? What does an integration testing flow with Quarkus look like?)

Supercharge Your Java Development with GitHub Copilot

With a series of short demos, Ashu will guide you through the secret sauce of how GitHub Copilot works in your IDE.

Getting the best from AI tools takes more than a simple prompt, and Copilot is no exception. This interactive, live session will take you on a tour through the details of Copilot and leave you with a deeper understanding of how to steer it effectively. You’ll learn what’s really happening behind the scenes, how Copilot interprets your code context, and what makes it sometimes brilliant—and sometimes baffling.

By the end of the session, you’ll know how to craft better prompts, understand Copilot’s limitations, and unlock practical techniques to make it your most productive coding partner rather than a random autocomplete engine.

The Enemy Within: How AI is Weaponizing Your Code

AI-generated code has become a double-edged sword, offering unparalleled productivity while quietly introducing vulnerabilities and weaknesses. Whether through poisoned models, maliciously crafted to inject flaws or poor-quality training data, your trusted AI companion could be a Trojan horse. This talk unveils the dark side of AI in software development, exposing how attackers exploit AI to compromise open-source projects and infiltrate the software supply chain.

Learn how bad actors leverage sophisticated techniques to embed security flaws in libraries you trust, and discover how untested, AI-generated solutions can open doors to catastrophic exploits. In the battle for secure software, your tools could be your greatest weakness or your first line of defence. Prepare to confront the chilling truth about AI and your code
