What we’re about
The Connecticut Java Users Group organizes monthly meetings on new and emerging Java technologies. It aims to help professionals stay abreat of the latest developments in Java and related open source projects. Meetings are free and open to the public. The group was initially founded in 2000 as a special interest group of the Connecticut Object Oriented Users Group. It is presently chaired by Ryan Cuprak who assumed leadering of the JUG in December of 2002.

November Meeting: Your Undead Code is a Time Vampire
Undead code, it wants to suck your time... Erik helps organizations slim down their Java codebases by identifying and deprecating code that no longer runs. Having celebrated 30 years of Java earlier this year, many apps pre-date the cloud and have undergone plenty of architectural changes over the years. Many talks focus on how to build features, this one will do the opposite: how can you watch an application run, figure out what doesn't run, and declutter your own code. As a result of removing code, your team will spend less time on maintenance, remove flakey tests, and focus more on feature work that actually matters.

Dangremond Family Commons - Trinity College, 300 Summit Street, Hartford, CT, USJoin us for a guided tour through the possibilities of the LangChain4j framework! Chat with virtually any LLM provider (OpenAI, Gemini, HuggingFace, Azure, AWS, ...)? Generate AI images straight from your Java application with Dall-E and Gemini? Have LLMs return POJOs? Interact with local models on your machine? LangChain4j makes it a piece of cake! We will explain the fundamental building blocks of LLM-powered applications, show you how to chain them together into AI Services, and how to interact with your knowledge base using advanced RAG.
Then, we take a deeper dive into the Quarkus LangChain4j integration. We'll show how little code is needed when using Quarkus, how live reload makes experimenting with prompts a breeze and finally, we'll look at its native image generation capabilities, aiming to get your AI-powered app deployment-ready in no time.
By the end of this session, you will have all the technical knowledge to get your hands dirty, along with plenty of inspiration for designing the apps of the future.
