Mentorship: the foundation of a healthy tech industry
A brief review of some of the cases of knowledge & technology being lost across history, (EG library of Alexandria) and why this is a significant threat with a rapidly advancing technological landscape. An overview of some of the biology that underlies human development & learning, and how this affects the mentorship landscape. An examination of different developmental relationships that rely on a mentorship-like relationship, focusing on highlighting key lessons from each. A practical step-by-step example of how these lessons have been and can be used in our own mentorship relationships.

Kotlin Multiplatform Mobile for Skeptics
Kotlin Multiplatform Mobile (or KMM) is a new SDK from JetBrains that allows iOS and Android developers to share code between the two platforms. The shared code is written in Kotlin. Typical use cases include: sharing networking, data storage, internal libraries, and algorithms, but the choice is yours!
While most Android developers love writing their apps in Kotlin, iOS developers are understandably wary of adopting KMM. This talk will give both iOS and Android developers the tools to confidently get started with KMM. This talk will include:
- An introduction of KMM and its benefits.
- A demo showing how to create a basic app with KMM.
- An argument for KMM, based on my research and journey from KMM skeptic to realist. I’ll also share the thoughts and experiences of others.
By the end of this talk, I will have covered enough content for teams to get started with KMM in their existing codebases and start reaping the rewards of this exciting new technology.

Sweet Streams (Are made of this)
As business needs change when new ideas are created, we need to orchestrate flows that can implement these ideas quickly. This talk shows how Spring Cloud Data Flow can address these needs using a toolbox of pre-existing and custom-built stream apps.

Imperative, declarative, functional, object oriented: four of a Kotlin kind
Is Kotlin a functional language? Yes, but... Is it object oriented? Yes, but...
Looking at four concepts: imperative, declarative, functional and object oriented
How does Kotlin make it easy to use either or all at the same time. This talk contains: Some useful Kotlin tips, some guidelines and pitfalls for the four concepts, traces of definitions and software history. After listening to this talk you will understand what these concepts are, what each is good for and how they are supported by the Kotlin language.

Java, Docker and Memory (The 3 Musketeers?)
Deploying a Java application to a PRD environment means knowing what kind of resources it needs to run, but how do you know that a head of time?Sure, its easy to give an application more hardware, but if with the rise of Kubernetes more Java applications are being deployed in Docker containers. Most Kubernetes environments want to know what resources the Java application needs to assist with scheduling and balancing the load across nodes.

Java resilience: How strong is your blend?
Troubleshooting large, distributed systems is hard. When production is down and you need to fix it as soon as possible, what do you do? In this talk I will talk about tools available to help you find and reproduce problems and also touch on resilience patterns for Java applications.

Jakarta NoSQL Powered by Cosmos DB on the Cloud
Jakarta NoSQL is a new standard for accessing non-relational databases on the cloud. Cosmos DB is a best-of-breed planet scale NoSQL database on Azure that is compatible with MongoDB, Cassandra and Gremlin.In this session we will see how to use these technologies together in cloud native Jakarta EE applications. Most of the session will be demos with a minimal number of slides.

Fourier Analysis Visualisation and it’s Application in 2D Drawings
Mathematics has been dubbed the “language of the universe” and yet it remains a daunting subject for most people. In my attempt to show the beauty and power of mathematics, I’ll be visually demonstrating and explaining the simple concept of Fourier Analysis (what’s in a name right?) and how I applied it in a 2D drawing software that I developed in Java, inspired by the impressive work done by sketch artists.
