Talk #1: JDK25 - Let's Talk the Awesomeness
Time: 10.00 am to 11.00 am

Let’s share how JDK 25 enables real-world applications. Although JDK 25 is less than six months old, diving deeper into its enhancements and JEPs has been truly mind-blowing.
I’d love to focus the discussion on:

• Runtime improvements
• A developer’s paradise
• Startup and peak performance gains
• GC: a new state of excellence

**Mode: 30 percent talk, 50 percent code runs, 20 percent statistics evaluation.**

Vaibhav Choudhary & Sathish Kumar Thiyagarajan

Talk #2: OpenJDK 25 @25
Time: 11.00 am to 12.00 pm
This talk is part history lesson and part look into the future, coinciding with the release of Java 25 and 25th year since it was first open sourced as OpenJDK. OpenJDK’s journey from its proprietary origins of Java technology to a collaborative open-source platform represents one of the most significant transformations in enterprise technology. We will trace OpenJDK's evolution from Sun Microsystems' strategic decision in 2006 to open source Java, through Oracle’s stellar stewardship of the project to the current state of the project in which major tech giants participate. We will talk about the part Linux distributions played in growing Java’s reach. We will also examine how it has shaped the modern Java ecosystem and how it will continue to do so, especially from the India point of view.

We will discover how India—once a consumer of open-source—has become a major contributor, now surpassing the US in open-source contributor count. We'll examine concrete opportunities for developers to contribute to OpenJDK and other projects and shape the future of OSS, transforming from users to stakeholders.
Speaker(s) :
Samir Kamerkar is the Director of Engineering at Canonical, the company behind Ubuntu Linux, where he leads the Language toolchains and Runtimes team at Canonical who contribute heavily to open source language tool chains like Java, Python, .Net, Go and Rust.
Samir has been a first hand witness to the evolution of Java over the last 30 years starting his Java journey with applets in v1.2; developing enterprise software with JSP / Servlets, SOAP, J2EE and other Java technologies; leading the cloud runtime transformation of IBM’s OpenJ9 and Semeru Runtime; and now transforming the developer experience not only for Java but for other language application developers as well on Ubuntu Linux.

Talk #1: Reading systems together
Time: 12.00 pm to 1.00 pm
Modern software stacks look magical from the outside, but their core is surprisingly simple and elegant! instead of talking about systems, what if we read them together? lets explore the kernel code of widely used systems (jvm, cloud runtimes, ai engines, event loops) and interpret each line, guided by their design. this is our 2026 experiment: slower learning but deeper understanding, informal conversations but with long lasting impact!
Speaker(s) :
Gireesh Punathil is an inventor, leader, mentor, author and speaker as well as committer or steering committee member for several leading open source projects. He is a Senior Technical Staff Member at IBM, and develops and supports Java and Eclipse runtimes. He is a prolific speaker and an advocate of polyglot languages, runtimes, tools and frameworks.
