We're honored to be hosting Ted M. Young again with a second Talk about Event Sourcing!
This will be in english, hosted at Gridfuse!

Agenda:
Doors: 17.45
Presentation: 18.00
Pizza: 19.30

Abstract
Following up on Ted's introductory Event Sourcing talk, this Ted Talk dives deeper into how to use the Event Modeling diagramming method to design application features. After getting everyone up to speed on the basic terminology of Event Sourcing, we'll see how to diagram and implement different kinds of "read models" (customized views of application state) for different purposes.

We'll also look at diagramming and implementing two different kinds of automations, also known as Processors: Actuators, which respond to specific events by triggering new Commands, and Translators, that turn internal private events into external integration (or collaboration) events that can be sent to other systems or Bounded Contexts.

We'll finish by looking at some Event Migration techniques for dealing with the inevitable changes to the way events are stored when they need to hold new information, or the same information, but in a different format.

Our speaker Ted M. Young:
Ted M. Young (he/him) is a Java trainer, coding coach, speaker, and author. He’s been in software development for over 30 years, teaching and coding in Java since the 1.0 beta, and doing eXtreme Programming since 2000.

Ted has worked for eBay, Google, Apple, and Guidewire Software. He is now an independent educator, helping those new to the industry and experienced folks increase their joy in coding by making code more testable.

Ted’s favorite techniques are test-driven development, refactoring, domain-driven design, and testable architectures, such as Hexagonal Architecture and Event-Sourcing.
Pizza and Drinks are on Gridfuse, thanks a lot!

Bei dieser Sonderedition unseres Open Tech Meetup möchten wir Code & Design interessierte Menschen zusammenbringen mit Menschen, die sich für Vereine engagieren.

Website-Frust, fehlendes Logo, ein Flyer, der einfach nicht fertig werden will, oder KI-Ergebnisse, mit denen ihr nicht wirklich weiterkommt – wenn euer Verein an genau solchen Stellen hängt, seid ihr hier richtig.
Oder du hast Lust auf Coding & Design in deiner Freizeit, aber dir fehlt das passende Projekt – dann bringen wir euch zusammen.

Ablauf
Wir starten mit einer kurzen Vorstellungsrunde – wer ihr seid, was ihr braucht oder was ihr anbieten könnt. Danach schauen wir gemeinsam, wer zu wem passt, und arbeiten in kleinen Gruppen an den mitgebrachten Themen weiter.
Ihr müsst nichts vorbereiten, keine Frage ist zu groß, keine Idee zu klein. Kommt einfach vorbei!

For this special edition of our Open Tech Meetup, we want to bring together people who are into code & design with people who volunteer for nonprofits and associations.
Website frustration, a missing logo, a flyer that just won't get finished, or AI results that aren't really getting you anywhere – if your organization is stuck on exactly these kinds of things, you're in the right place.
Or maybe you're into coding & design in your free time but missing the right project – then we'll bring you together.

Agenda
We'll start with a short round of introductions – who you are, what you need, or what you can offer. From there, we'll figure out together who's a good match, and work in small groups on the topics you bring along.
You don't need to prepare anything, no question is too big, no idea too small. Just come by!

Code of Conduct
Everybody who participates in our meetup is required to conform to our Code of Conduct: https://nullaufeins.org/en/codeofconduct/

Contact
If you have any questions, please contact us here, or by e-mail: events@nullaufeins.org

We look forward to meeting you!

Diversity is key for IT!

DiversIT #9 brings together diverse perspectives on one of the most pressing questions of our time: How can we shape a digital future that is innovative, inclusive, and truly human-centered?

This edition explores the role of women in artificial intelligence, the realities of building and scaling a startup in the tech sector, and the importance of culture, belonging, and human connection in increasingly digital workplaces. Additional perspectives from digital transformation and public sector innovation will highlight how technology, policy, and society can work together to create lasting impact.

Together, these impulses open up a space for inspiration, reflection, and meaningful exchange. From AI and entrepreneurship to leadership, digital strategy, and cultural fit, DiversIT invites participants to discover how diverse experiences and perspectives drive innovation, strengthen communities, and help shape the future of technology.

Join us for an afternoon of authentic stories, fresh ideas, and conversations that challenge, connect, and inspire.

– 100 € Business Ticket, if your company is willing to pay for your ticket we can use this to cover event costs.

Everlock is a self-hosted Rust application built around a simple idea: application data lives in Git repositories.
Instead of exposing Git directly, Everlock puts adapters around that common storage model. Some speak protocols such as SMTP, IMAP, CalDAV, WebDAV and HTTP; others provide compatibility with photo apps, password managers, container tooling and MCP clients.
In this talk, we will look at where Git maps surprisingly well to application concepts, where the abstraction starts to leak, and how Rust helps tie many very different interfaces to the same underlying data.
And because “everything is Git” was apparently not controversial enough, Everlock is built as a single Rust monolith containing storage, protocol servers, adapters and background jobs.
The talk is less about Git as version control and more about Git as an application storage primitive.

Programmiere deinen eigenen Discord-Bot – mit KI-Power!

In diesem 3-stündigen Workshop lernst du die Grundlagen der Discord-Bot-Programmierung in C#. Du erfährst, wie der Bot auf Nachrichten reagiert, Befehle ausführt und mithilfe externer KI-Dienste Texte verarbeitet oder generiert.

Schritt für Schritt führen wir dich durch das Setup, den sicheren Umgang mit Tokens und die Einbindung von KI-APIs. Am Ende besitzt du einen funktionsfähigen Discord KI Bot, den du direkt auf einem Server einsetzen kannst.

Vorkenntnisse sind nicht erforderlich. Der Workshop ist perfekt für Einsteiger, die praxisnah Programmierung und KI-Anwendungen kennenlernen möchten.
