Eric Lavigne will give a presentation on Clojure. Clojure abstract
Clojure is a dynamic programming language that targets the Java Virtual Machine. It is designed to be a general-purpose language, combining the approachability and interactive development of a scripting language with an efficient and robust infrastructure for multithreaded programming. Clojure is a compiled language - it compiles directly to JVM bytecode, yet remains completely dynamic. Every feature supported by Clojure is supported at runtime. Clojure provides easy access to the Java frameworks, with optional type hints and type inference, to ensure that calls to Java can avoid reflection.
Clojure is a dialect of Lisp, and shares with Lisp the code-as-data philosophy and a powerful macro system. Clojure is predominantly a functional programming language, and features a rich set of immutable, persistent data structures. When mutable state is needed, Clojure offers a software transactional memory system and reactive Agent system that ensure clean, correct, multithreaded designs.
This presentation will introduce the Clojure programming language. You will learn how to write simple Clojure programs, how to use Java code from Clojure, and how to use Clojure code from Java. You'll learn how to use agents and software transactional memory to make multithreaded programming easier. You'll also see a few examples of how Clojure can save you from re-implementing the same patterns over and over again.

We will have several interesting things to raffle off, including a ticket to the upcoming Miami Flex event! See the event here in Codetown events for details.
Codetown is a social network. It's got blogs, forums, groups, personal pages and more! You might think of Codetown as a funky camper van with lots of compartments for your stuff and a great multimedia system, too! Best of all, Codetown has room for all of your friends.

At QCon London 2026, Spotify's Jo Kelly-Fenton and Aleksandar Mitic discussed Honk, an AI-powered coding agent that enables code migrations across Spotify's codebase. The system improves migration, reducing timelines drastically and addressing complexities that traditional scripts could not. Key challenges included handling edge cases and standardizing the codebase to facilitate review processes.

HubSpot engineers introduced Sidekick, an internal AI powered code review system that analyzes pull requests using large language models and filters feedback through a secondary “judge agent.” The system reduced time to first feedback on pull requests by about 90 percent and is now used across tens of thousands of internal pull requests.

In a talk at QCon London 2026, Viktor Petersson argued that software teams are running out of time to adopt SBOMs (Software Bills of Materials) due to pending legislative changes in both the US and Europe. He walked through the current regulatory landscape, spoke on the practical mechanics of generating high-quality SBOMs and on the emerging standards for distributing the resulting artefacts.

Rafael Ring discusses the architectural evolution of server-driven UI at Nubank, moving from static mobile binaries to a sophisticated scripted framework called Catalyst. He explains how they implemented a tree-walk interpreter in Flutter to render dynamic layouts and logic from JSON payloads.

Oracle has released version 26 of the Java programming language and virtual machine. As the first non-LTS release since JDK 25, the final feature set includes 10 JEPs, five of which are still progressing through the preview and incubator stages. This release focuses on Java library improvements, language innovation, performance and security.
