The One with Java 2022

Why can’t we “just make it go faster”? First we need to work out “Faster for whom?” and “Why?”…and “What even is faster?” Holly Cummins takes you through Java optimization principles before bouncing through the pitfalls. Join in to discover why the exact same techniques that make Quarkus rocket fast used to be a terrible idea, why fast benchmarks make for slow programs, and why despite all that, optimization really matters. Along the way, you’ll also dive into measuring things, bad advice, garbage collection, and climate change.

As our craft matures, I keep noticing more and more software professionals striving to improve the quality of their work. One of the means towards this goal is the practice of writing clean code, which is getting a lot of attention lately, and developers turn to it in an effort of improving the quality of their output.

In this presentation, I aim to share with you a few less advertised tips relevant to the subject of clean code. Depending on who you are and how you are accustomed to writing code, you may find these tips to be common sense, surprising, or perhaps even shocking. In any case, I hope you find them useful, or at least that they may inspire you to look at certain coding aspects from a different perspective.

If ( you did not hear about Quarkus ) or ( you did but never actually played with it in a project ) then

This session could be of interest for you;

The session tries to raise awareness about Quarkus capabilities which often are misunderstood, is it just an alternative to Spring Boot (but immature) or is a lot more than that.

We will have some hands-on coding to take a glance into the nice coding features the hopefully other frameworks will adopt in the future.

But we will also do a reality check of using Quarkus in a greenfield project and will look at lessons learn and limitations.

And I will share my humble opinion when it comes to proposing Quarkus as an option for different use-cases (being migration of existing solution or green field projects).

JHipster is a set of tools that can help you quickly build web applications. It is composed of two main components: a modern UI framework and an API.
This presentation will provide an overview of JHipster and will walk you through the steps of starting an angular & spring boot application.

Have you ever wondered why it feels like it does to write code? Have you ever stopped and thought “if this is supposed to be such an intellectual exercise, why am experiencing so many emotions, from the heights of elation, to the pits of despair?”.

I have.

Since this first occurred to me years ago I’ve pieced together a theory which I believe gives not only an explanation for such mental states, but also offers a new means of evaluating how we work with software, and perhaps even becoming better at it.

In this session I’ll explain the theory, bringing in the latest views from neuro- and cognitive science. I’ll then consider how it can be applied, not only explaining how it feels to write code, but also interrogating why each of us has such wildly different experiences. In doing so you’ll gain a far deeper understanding of this daily activity, and consequently drive significant personal improvements.
