Do you love to maintain code that you didn’t write? Probably not…

As systems grow and evolve, the codebase inevitably accumulates clutter, including unused or “dead” code. Often, the developers who wrote that code are not even in the company anymore. So how do you know if the code is still used? Dead code can be confusing and it can be the source of vulnerabilities in your code base. So it is not only “legacy” code we have to deal with, but also “dead” code and even so-called “zombie” code.

This session will give you an overview of the common struggles with these types of code and it will try to give you an idea about the differences between those types of code and about tools like JaCoCo or OpenRewrite in combination with Intelligence Cloud, that will help you to get rid of it.

How many times have we asked ourselves if it is a good idea to release to production on a Friday afternoon? Is the production software sufficiently robust and/or resilient to vulnerabilities? How can we detect and correct security problems in production? Better yet, how can we prevent such problems or attacks?

In recent years the topic Software Supply Chain Security has taken on greater importance. Concepts like SBOMs, SLSA, Reproducible Builds, CI/CD Security are widely discussed to answer the previously posited questions. In this session we will discover what are these concepts and how you may apply them to your own projects.

Since ChatGPT rocketed the potential of generative AI into the collective consciousness there has been a race to add AI to everything. Every product owner has been salivating at the possibility of new AI-Powered features. Every marketing department is chomping at the bit to add a “powered by AI” sticker to the website. For the average layperson playing with ChatGPT's conversational interface, it seems easy however integrating these tools securely, reliably, and in a costeffective manner requires much more than simply adding a chat interface. Moreover, getting consistent results from a chat interface is more than an art than a science. Ultimately, the chat interface is a nice gimmick to show off capabilities, but serious integration of these tools into most applications requires a more thoughtful approach.

This is not another “AI is Magic” cheerleading session, nor an overly critical analysis of the field. Instead, this session looks at a number of valid usecases for the tools and introduces architecture patterns for implementing these usecases. Throughout we will explore the tradeoffs of the patterns as well as the application of AI in each scenario. We'll explore usecases from simple, direct integrations to the more complex involving RAG and agentic systems.

Although this is an emerging field, the content is not theoretical. These are patterns that are being used in production both in Michael's practice as a handson software architect and beyond.

Architects must maintain their breadth, and this session will build on that to prepare you for the inevitable AI-powered projects in your future.

Some of the most challenging issues a developer will face are slow developing resource leaks, or errors that occur at infrequent intervals. When these issues arise, finding the root cause can be challenging, and developers often resort to adding numerous logging statements around suspected problem areas.

Building modern, reliable applications requires a complex architecture consisting of microservices, queues, databases, and more. The challenge is that everything fails. It’s just a matter of time. Unstable networks, unreliable APIs, and overloaded queues require developers to write extensive additional code to handle all the failure conditions.

Once the application and all of its components are running in production, observing its behavior through the myriad of systems is an exercise in frustration.

What if you could guarantee that any series of services would never fail? What if there is a better way to create, test, and debug reliable applications?

Temporal is an open-source programming model that simplifies your code, makes your applications more reliable, and helps you deliver more features faster. It abstracts away the complexities of retries, rollbacks, queues, state machines, and timers, so that developers can spend their time focused on writing business logic instead of managing all the failure conditions.

Temporal introduces a new paradigm that helps you manage simple tasks or a series of complex procedures, ensuring they are executed reliably until completion, or they will fail elegantly. Developers use their preferred language and development tools, incorporating the Temporal SDK to build reliable applications. Testing becomes as easy as writing and running unit tests.

Java is not only the server language running on heavy machines! You can do amazing stuff with it on a small single-board computer and gain new knowledge simultaneously, like controlling electronic components and different communication protocols.

A Raspberry Pi is a complete Linux PC with a small form factor with a low price. And, of course, you can run Java on it. The same kind of JVM applications you know, love, and use on heavy machines can also be used on the Raspberry Pi. "Write once, run everywhere"? Ah yes, that's Java's promise! But this small board has some additional possibilities you will not find on that fancy server you are running somewhere in the cloud. All Raspberry Pis have those 40 magical pins to connect unlimited electronic components. Measuring temperatures and distances, toggling LEDs and relays, controlling the content on an LED matrix or LCD display, playing the Star Wars tune on a buzzer... the only limit is your imagination!

In this talk, we'll look at the current state of Pi4J (www.pi4j.com) and dive into the code of a few examples. We'll experiment with Java on a CrowPi - a Raspberry Pi-based laptop to interact with electronic components. Let's also add Spring Boot and Vaadin into the mix to build a web interface to expose the data of those components. And while we're doing all this, we will learn how to reduce the total energy and ecological cost of our data transfers by making better use of bits and bytes.

12:00PM-1:00PM EST Presentation with Q&A

LLMs are data-hungry, and when it comes to source code, more than the text is needed to make large-scale inferences about a codebase. Code has a unique structure, strict grammar, dependencies, and type information that a compiler must deterministically resolve. This information could be beneficial for AI but is invisible to the text of the source code.

For example, try to answer even a simple question about where Guava is used or where a particular logging library is used. While developers can find references in the code, the code-as-text may not have a reference to the library you are looking for. Imagine a logger instance inherited as a protected field from a base class defined in a binary dependency. The import statement that identifies which logging library that logger is coming from is IN the binary dependency, not in the text of the call site. A human would do no better in this situation.

This talk addresses improving AI accuracy for large-scale code refactoring by enhancing the data source. We’ll explore a state-of-the-art code data model called the Lossless Semantic Tree (LST) that’s part of the open-source OpenRewrite auto-refactoring project. The LST and recipes are straightforward tools to equip LLMs with the data they need to make accurate decisions.

The common excuse for inaccuracy or incompleteness in output is that LLMs will improve, but the models are good enough. What they too often need is the data to make inferences. We’ll show why when evaluating LLMs for large-scale automated refactoring:

• If it's based on text, you don't want it
• If it's based on AST, you don't want it

Join us for a hands-on introduction to Actix Web, one of Rust's most popular and performant web frameworks. Whether you're new to web development in Rust or exploring alternatives to other frameworks, this talk will get you up and running with Actix Web.

We'll begin with a brief overview of Actix Web's architecture and ecosystem, and discuss why it stands out among Rust web frameworks. Then, we'll dive into building a real application together, covering essential concepts like routing, handlers, extractors, and error handling.

By the end of this session, you'll have a solid foundation for building your own web services with Actix Web and understand the trade-offs that make it an excellent choice for many Rust projects.

What to expect:

• Introduction to Actix Web and the Rust web framework landscape
• Live coding walkthrough of an example application
• Practical tips for getting started with your own projects

Prerequisites: Basic familiarity with Rust. Bring a laptop if you'd like to code along!

First, we will show the backend code to implement a REST API on the serverless Wasm cloud platform Fermyon Spin. This will include the composition of Wasm components compiled from both Rust and a different programming language. Second, we will show the code for a single page application (SPA) using the React-like Rust-based frontend framework Dioxus. This will include static prerending with client-side hydration for search engine optimization (SEO) using the new static site generation (SSG) option.
