A Freakonomic Take on Open Standards and Jakarta EE

Java Stage — 45 minutes Java

Words like standard, de-facto, de-jure and open are frequently used and abused in our industry. The reality is that few people really understand what these words actually mean or how these ideas effect their own professional lives in the long and short term. This session aims to clear the air on some of these terms and outline why open standards like Jakarta EE are critically important to you today and in the future. We will explore these concepts in the context of well-established economic theories on competition, monopoly power, the network effect, innovation, open source and open standards - in true Freakonomist style!

Managing AI-powered Java App With API Management

Java Stage — 45 minutes Java

ChatGPT enabled us to build custom plugins that let ChatGPT call any API data intelligently, while OpenAI API makes available effective AI models for developers through REST. It generates a user-friendly answer by combining the API data and its natural language capabilities. As the usage of AI grows, we need scalable, performant, and secure API integrations.|
This talk will explore the benefits of integrating an open-source Apache APISIX API management solution with the OpenAI API to define cross-cutting concerns for your AI-powered Java Spring boot app API. From security to rate-limiting features, we will cover everything you need to know to get started with this integration. You will see the demo of how to build an end-to-end production-ready AI-featured Java app.

Maximising developer productivity: How governance can make the difference

Java Stage — 30 minutes Java

In the world of software development, governance is often seen as a process-heavy framework that conflicts with the agility and fast pace required by product teams. 
However, this talk challenges this misconception by highlighting how effective governance can maximise developer productivity. By establishing clear guidelines, defining responsibilities, and standardising processes, governance provides a solid foundation for efficient and effective teamwork.

Effective Transactions Management with Spring

Java Stage — 30 minutes Java

Are you interested in developing concurrent applications that need to run safely and correctly? Are you looking for efficient ways to separate each transaction execution, isolated from the other ones? Are you interested in analyzing the mechanisms provided by Spring for effectively managing concurrent transactions? Working with transactions is a science and an art, and the talk will examine the main concepts of Spring Transactions and the mechanisms behind them. We’ll demonstrate their effective implementation in an application, debugging the concurrent executions while varying their essential parameters, such as isolation and propagation. Listeners will find out how to develop Java concurrent applications using Spring Transactions and how to effectively manage their parameters. We’ll also dive into debugging the way the isolation and propagation parameters work, demonstrating and analyzing concurrent transactional executions. The talk will be highly oriented on analyzing and debugging the transactional code.  Read More...
