**Presentation:**
**Async Is the New 'goto': What Modern Java Concurrency Is Really About - Wout Werkman**
For years, we’ve relied on asynchronous functions—from simple thread launches to observable subscriptions and event handlers. While these tools solved our scaling problems, they quietly broke the fundamental rules we never knew we loved (spoiler, it’s structured programming!). They act like modern-day goto statements, ripping execution out of predictable scopes and making cancellation, exception handling, and resource management notoriously difficult to reason about.

In this talk, we will learn what we can gain from Java’s upcoming structured concurrency feature. We will use a custom-built visual debugger to give you, I dare to say, the last explanation of structured concurrency you will ever need!

Join me to discover how we can un-break our concurrent programs, regain the strict guarantees we lost, and safely confine the complexity of running millions of concurrent tasks.

Async Is the New 'goto': What Modern Java Concurrency Is Really About

Julemøtet til javabin Trondheim blir med god mat og drikke på E.C. Dahls!

Kvelden vil forløpe omtrent som følger:

* Vi åpner vårt lokale kl 17.00. Da blir det mulighet til å slå av en prat med andre dukes og kjøpe seg forfriskninger i baren etter eget ønske.
* kl 17.30 får vi servert en fantastisk 3-retters, spandert av javaBin. Da utvalget i god drikke er stort blir det opp til hver enkelt å velge og finansiere sin egen drikkepakke til menyen. Vi koser oss med god mat og drikke og gode historier om strandede prosjekter og det neste nye kule i teknologimiljøet.
* ca 18:30 starter den faglige delen.

OBS: Hvis du har allergier, eller det er andre forhold vi må melde fra til kjøkkenet om, og du ikke sa fra da du meldte deg på, vennligst send oss en melding, eller kommentér på meetupen så fort som mulig!
Vel møtt!

**Change-data-capture with Debezium and Kafka (English)** **- *Remi Guittaut***
Plenty of use-cases warrant replicating data between systems, whether for auditing purposes, data analytics, Backup, migrations, etc. This was traditionally an inefficient burden, putting strain on databases, not real-time, etc. With change data capture, we can push change events in real time to Kafka, with near 0 impact on databases. As it turns out, it was in the database log all along, and gives us our data instantaneously, reliably, in order, and at scale.

**Presentation(s?)**
**Mise-en-place - The front-end for your dev env - Karl Yngve Lervåg**
*(The presentation will be held in English.)*

`mise` is a CLI tool designed to help developers maintain the correct versions of dev tools for any specific project.
Many developers work on multiple different projects.
We might even change projects often.
Each project may have their own set of requirements, such as the right version of Python, Java, Node, or whatnot.
`mise` makes it easy, almost trivial, to specify and satisfy these requirements per project in such a way that you always have the right tools for the given context.

In my presentation, I'll show how to use `mise`.
I'll cover the main tool features, including how to use it in a CI/CD pipeline.
And if there's time, I'll show some of the other features as well!

**Do you have a short (10-30 mins) presentation about a devtool you love, that you'd like to present? Get in touch with us!**
