In diesem Kurs beschäftigen wir uns mit verschiedenen Texten aus unterschiedlichen Bereichen. Das können u.a. kurze Geschichten, Gedichte, Zeitungsartikel, Kolumnen oder Videos sein. Immer sind es Themen, die uns gefallen, die wir besonders interessant, wichtig oder manchmal auch richtig schlecht finden. Gemeinsam versuchen wir die Position der Autor*in, den Stil und die Argumentationsstruktur zu verstehen. Dazu diskutieren wir über das, was wir verstehen, welche Meinung wir zu dem Thema haben oder welche Fragen offen bleiben.
Gerne könnt ihr uns auch Themenvorschläge mitbringen oder zuschicken.
Der Kurs richtet sich an interessierte Menschen mit einem B2-Niveau (oder so ähnlich), die Lust haben sich weiter mit der deutschen Sprache zu beschäftigen und ihren Wortschatz zu erweitern.
Die Termine sind sporadisch.

Whether you are new to GitHub Copilot or already using it, this event will help you better understand how to apply AI-assisted coding techniques in everyday development hosted at **adesso SE**. **Sessions & Workshops** 1. **GitHub Copilot in practise - Sandra Ahlgrimm** 2. **Let's create a tiny AI library together, Copilot powered - Johannes Bechberger** 3. **GitHub Copilot Hands-on workshop - bring your laptops!** **Location** [Prinzenstraße 34, 10969 Berlin](https://www.google.com/maps/place//data=!4m2!3m1!1s0x47a84e50ecd583e3:0xde16d03634776e3b?sa=X&ved=1t:8290&ictx=111) **Agenda** 17:30 - doors open 18:00 - warm welcome by JUG leader **Sandra Ahlgrimm** and **Gregor Böhme** from **adessoSE** 18:15 - first session 18:40 - second session 19:30 - workshop **Abstracts** **Let's create a tiny AI library together, Copilot powered** We all want to do it. When you want to integrate AI into your tools, what do you do? You add LangChain4j or SpringAI and run with it. But do you know how these libraries interact with the AI service providers or your local llama-server instance? These libraries aren't magic, so let's peek behind the curtain and write a tiny AI library together. This way you'll discover the REST APIs that power it all. **Speaker** **Johannes Bechberger,** a nerd passionate about compiler building and program analyses that enjoys cooking and works on the JVM at SAP ([LinkedIn](https://www.linkedin.com/in/johannes-bechberger-381296149)), making profiling easier for everyone. **Sandra Ahlgrimm** is Senior Developer Advocate working for Java Developers with Microsoft at GitHub.

Hello Gophers, Welcome back for another year of Go talks and networking! Would your company like to host our meetup? Let us know! If you'd like to give a talk - submit your proposals here: http://goo.gl/forms/54YvJT223F All talk formats work: short talks (5-10 min) as well as regular length (25 min). If you have more ideas - talk to us at the Gophers slack: https://invite.slack.gobridge.org/ in the #berlin channel, and follow us on twitter: https://twitter.com/gdgberlingo **Speakers**: *Simon Schulte* is a Tech Lead with nearly a decade of experience building scalable backend systems across fast-paced product companies. With a background in business informatics and a passion for Golang, cloud infrastructure, and DevOps, he has spent his career solving complex engineering challenges. He is particularly excited about leveraging AI and LLM workflows to eliminate the tedious, repetitive work that slows developers down — think tech debt, boilerplate, and documentation — so engineers can spend their energy on what actually moves the needle. For Simon, AI isn't about replacing developers; it's about giving them back their time. *Daniel Peralta Madriz* is a backend engineer from Costa Rica with around 6 years of experience working with Golang, although, sadly, he's been spending most of his time lately working with Node.js :(. He is interested in distributed systems, scalability, and developer experience, and is currently experimenting with how to leverage LLMs to safely and autonomously execute repetitive tasks. *Michael Morgen* is a Platform/infra engineer by day, runtime and network optimizations by night. Join in person at: **Talon.One** Talon.One is the incentives engine behind 300 of the world’s most-loved brands, unifying loyalty and promotions on a single flexible platform. Their customers run millions of real-time incentive decisions across markets, channels, and use [cases.As](http://cases.as/) incentives become more strategic than ever, they are continuing to raise the bar for what businesses can build and how fast they can build it Wiener Str. 10, 10999 Berlin https://maps.app.goo.gl/8eMjgWes1E4TBA3c7 or virtually at: https://www.youtube.com/live/qh__TQ1bMF0?is=hw21pk0ZE3HGyaaT *** Agenda 10:49 PM: Networking Networking over drinks and food 7:30 PM: Welcome Welcome words from the organizers 7:35 PM: Talk 1: Go-ing Against the Chaos: Deterministic LLM Workflows / Daniel Peralta Madriz (Backend developer) & Simon Schulte (Techlead of Webhooks and Notifications) @ Talon.One LLMs are powerful, but “it works most of the time” isn’t good enough for production. In this talk, we’ll walk through how to design deterministic workflows around non-deterministic models using Go. From structured iteration loops to validation steps and guardrails, you’ll learn how to move beyond prompting and start engineering reliable LLM-powered systems 8:10 PM: Announcements and break Announcements, HR lost & found, open mic 8:30 PM: Talk 2: About Go Memory Allocator / Michael Morgen, Platform/infra engineer @ Mirantis A short talk about how Go gives memory to your program. We will look at the main allocator parts, why small allocations are usually fast, when Go asks the OS for more memory, and a couple of simple examples where this knowledge helps performance. 9:05 PM: Networking Networking over drinks and food *** Hosted By Natalie Pistunovich, Organizer Ole Bulbuk, Organizer Tim Scheuermann, Organizer Anderson Queiroz, Organizer Complete your event RSVP here: https://gdg.community.dev/events/details/google-gdg-berlin-golang-presents-hybrid-may-golang-meetup-1/.
