Hallo liebe Java User Group Mitglieder! Diesmal haben wir Thomas Künneth mit seinem Talk zum Thema "**Climbing the Codeberg - Some Developer's Thoughts on Leaving GitHub**" zu Gast. Wir freuen uns euch zu sehen (virtuell oder vor Ort). * 17:45 Uhr: Einlass * 18:15 Uhr: Talk * ab 19:00: Ausklang des Abends Dank an [codecamp:n](https://www.codecamp-n.com/) für Location, Bier und Pizza! \-\-\- As developers increasingly prioritize privacy, digital sovereignty, and true open-source values, many are questioning their reliance on corporate-owned platforms like GitHub. Enter Codeberg—a community-driven, non-profit Git hosting platform funded by donations and powered by Forgejo. But is the grass really greener, and how difficult is the transition? In "Climbing the Codeberg," we’ll explore both the philosophical motivations and the practical realities of leaving GitHub. Walking through a firsthand developer's journey, this talk will guide you through the process of establishing your code’s new home and taking back control of your workflow. In this session, we will cover: * The "Why": Understanding the fundamental differences in philosophy and legal structure between a corporate-owned giant and a non-profit, community-led alternative like Codeberg. * Safe Migration Strategies: Step-by-step insights on migrating repositories (including metadata like issues and releases), proving your identity via Mastodon, and utilizing "tombstoning" techniques to avoid critical security risks like namespace hijacking on your old GitHub account. * Restoring Automation: Leaving GitHub doesn't mean leaving CI/CD behind. We'll dive into leveling up your new environment by setting up local Codeberg Actions runners, exploring both containerized (Docker) approaches and host-level (act_runner) configurations for architectures like Apple Silicon. Whether you are ready to make the full leap to a community-owned forge or simply want to explore what true digital sovereignty looks like, this session will equip you with the tools, commands, and insights needed to successfully summit the Codeberg. \-\-\- Dein Vortrag bei der Java Usergroup Nürnberg! Hast du dich in letzter Zeit in deinem Projekt oder privat mit einem interessanten Thema beschäftigt? Vermutlich ist das nicht nur für dich selbst interessant! Hast du Lust, selber einmal einen Vortrag bei der Java-Usergroup Nürnberg zu halten? Wir sind nicht nur auf Java-Themen fokussiert, sondern beschäftigen uns gern mit und um alles über Software Entwicklung und IT. Wir wollen bei der JUG nicht nur bekannten Speaker\*innen eine Plattform geben und die neuesten State-of-the-Art Technologien vorstellen. Wir freuen uns auch besonders, wenn wir Themen aus unserem technologischen (Arbeits-)alltag Raum geben zu können. Melde dich gerne bei uns, wenn du dazu Lust hast, wir geben wenn gewünscht gerne auch Hilfestellung bei der Vorbereitung!

Vorträge, Networking und Apéro für alle, die sich in Winterthur für Webtechnologien interessieren. Türöffnung um 18:30 Uhr, Talks ab 19:00 Uhr. [https://web-winti.ch/](https://web-winti.ch/) **ARIA Demystified: Make Your Web Thing More Accessible** Mohammed Chelouti Praktische Einführung in die Entwicklung barriereärmerer Webseiten und -Apps. **It's About Time** Aleksej Dix Introducing useTemporal library to build calendar UIs much faster.

**About the talk** Legal topics are often treated as something that comes after design, product, or branding. In reality, every UX decision, every deliverable, and every shipped product already creates legal consequences, whether we notice them or not. In this talk, [Neena Kaiser,](https://www.linkedin.com/in/nskaiser/) [Ryccardo d' Alessio](https://www.linkedin.com/in/ryccardo-d-alessio-684337123/), and[ Tadas Zukas](https://www.linkedin.com/in/drtadaszukas/) explore the intersection of Legal × UX × Product × Personal Brand, focusing on real situations designers, founders, and builders face every day. Rather than legal theory or scare tactics, the session is grounded in concrete cases: ownership of design work, intellectual property pitfalls, client conflicts, branding protection, and the moments where teams realize too late that legal clarity should have been part of the process from day one. Through a live case example from Do Your Order, the speakers will show how legal thinking can actively support product growth and marketing instead of slowing it down. The session also introduces Juriscope, a legal-orientation tool designed to bring clarity to complex legal questions, demonstrated live using real UX- and product-related scenarios. T**he talk will also open space for discussion and feedback:** how legal tools should be designed, what designers actually need from legal support, and how we can make legal experiences more transparent, accessible, and human. **\-\-\-\> This will be an open space\, bring questions you would like the experts to Answer\.** **Expect practical takeaways** you can immediately apply to your own work, whether you’re freelancing, building products, scaling a startup, or shaping your personal brand shared through real cases, real trade-offs, and honest conversations. **About the speakers** [Neena Kaiser](https://www.linkedin.com/in/nskaiser/) Managing Partner at Juriscope and Global Transformation Leader. Neena shapes how emerging technologies become shared infrastructure. Her work sits at the intersection of law, technology and human-centered systems. She focuses on how responsibility, authorship, and trust are designed, distributed and sustained. [Ryccardo d' Alessio](https://www.linkedin.com/in/ryccardo-d-alessio-684337123/) Founder of Do Your Order. Ryccardo brings a founder’s perspective on building products, brands, and businesses and the legal blind spots that often appear when ideas move from concept to market. [Tadas Zukas](https://www.linkedin.com/in/drtadaszukas/) Senior Legal Counsel, CSP Senior Fellow, author specializing in sustainability, transition and impact finance. He will talk about his personal practical lessons learned from his real-life experiences at top tier global business organizations as a user of LegalTech tools and creator of legal content. [Juriscope](https://www.linkedin.com/company/juri-scope/) Juriscope is a legal-tech initiative aimed at democratizing access to legal knowledge. By combining legal expertise with thoughtful product design, Juriscope helps people understand their legal position early, before problems escalate and costs explode. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **💬 The Talk is in English** **📍 \*Note\* The event is happening in a new room \*note\* The event will be held at ETH Zürich Maschinenbau ML, Room F36** *We kindly ask you to arrive 10 minutes early of the event start, so everyone can find a seat due to high attendance.

Megaparsec is a well known Haskell parsing library, most often used to parse text. But a token stream doesn't have to be characters, it can be anything with the right instances. What if you fed it a stream of Aeson.Value instead? Extracting structured data from real-world formats is often a messy process. Presentation is optimized for human consumption, not for automated processing: What looks like a table is really a sequence of heterogeneous rows with little shared structure. JSON can serve as a useful interchange format in those cases, but parsing becomes much more complicated than matching keys to fields. Treating decoded JSON as a token stream and running Megaparsec over it gives you composability, meaningful errors, backtracking, and the full combinator toolkit. The talk is based on an hledger personal finance automation use-case, turning PDF invoice statements into hledger journal entries. This talk follows the [Zurich Friends of Haskell General Assembly](https://www.meetup.com/haskellerz/events/313322610/) that starts at 6pm in the same room, which all members are welcome to attend.

Web Zurich presents inspiring talks all about the web. Join us for the March 2026 meetup! We will have three talks as well as chit-chat and drinks. Whatapp: [https://chat.whatsapp.com/FxOfVTK9nf431xHtVl3eGK](https://chat.whatsapp.com/FxOfVTK9nf431xHtVl3eGK) Website: [https://webzurich.ch](https://webzurich.ch) 18:30 \~ 19:00 Arrival time with drinks, chat and introduction 19:00 \~ 19:40 *Christian Heitzmann* **Why Documentation Won’t Write Itself—and AI Won’t Save You** For the last 15+ years, I’ve joined and consulted software teams that all struggled with the same problem: nobody likes writing documentation, and everybody pays the price for it. New developers spend weeks reverse-engineering codebases, architecture lives in people’s heads, and wikis quietly decay into noise. With AI now entering the picture, many hope it will fill the gaps. It won’t. I’ll show the simple ideas that change everything: how to think about documentation in the right levels, how to keep it close to the code, and how to avoid the decay we all know too well. These are the decisions that have to be made before any tool or process can work. The documentation won’t write itself. But there are ways to make it far easier and far more reliable. 19:40 \~ 19:50 **Short Break** 19:50 \~ 20:10 *Marco Gähler* **How to write good code** There is an infinite amount of solutions how you can solve a programming problem. Some are better, others are worse. The best solutions are easy to understand, maintain and errors are not able to hide. I wrote a book "Software Engineering Made Easy" about this topic and I'm more than happy to explain some principles that make your code better. Most of them are quite simple to understand, once you understand the mechanics, why your code always breaks. 20:10 \~ 20:30 *Marius Ishida* **AI: The Lightsaber Problem** My talk will challenge the popular narrative that AI fundamentally democratizes power by showing that, which I believe is not true at all. While generative AI lowers entry barriers for basic tasks, it disproportionately amplifies the productivity and leverage of already computer literate users. Empirical research shows that AI acts as a skill multiplier rather than a true equalizer, with outcomes strongly dependent on users’ ability to frame problems, verify outputs, and integrate tools into complex workflows. As a result, AI risks reinforcing a new AI driven digital divide, where technical literacy—not access alone—determines who truly benefits. 20:30 onward More drinks & chat We look forward to see you there!

Every year the Zurich Friends of Haskell meet for a general assembly as per the [statutes of the association](https://docs.google.com/document/d/1-8eHAK40hiH5jv79AscWtf3pyUNxx4Ls1LwkpLYK--8/edit?usp=sharing). The purpose of the Zurich Friends of Haskell is to organize ZuriHac and the HaskellerZ meetup. The general assembly gives you the opportunity to learn what the association has been doing in the year 2025 and to contribute to ZuriHac, the HaskellerZ meetup, and the Haskell community in Zurich. The general assembly is open to all members of the ZFoH. If you are not a member yet, please head over to [the ZFoH website](https://zfoh.ch) and sign up for membership. The agenda is as follows: 1. The board will present a summary of the association's activities in 2025. 2. The treasurer will present the financial report for 2025. 3. We vote to discharge the board for their work in 2025. 4. We will discuss the goals and aspirations of the association for 2026. 5. We will elect the board for the years 2026 & 2027. Please let us know if you have further topics you would like to discuss. Note: members of the ZFoH will receive a separate invitation via email. Please RSVP to this meetup event anyway so we get an accurate picture of who will be attending. Thank you! Looking forward to seeing you at the GA! PS: We'll be holding a regular HaskellerZ meetup right after the general assembly, to be announced as a separate Meetup event. Please RSVP for that event separately once it is announced.

## (Lesson 2) ## What to expect Project Equilibrium is an in-person introduction to disciplined, rule-based trading automation. This first event is designed to be clear, practical, and approachable no hype, no pressure, and no prior technical background required. ### Why we meet (two-session structure) This meetup is structured as **two lessons**: **Lesson 1 — The “Why” (mindset + framework)** * What Project Equilibrium is (and what it is not) * Why we focus on process, rules, and execution discipline * What “24/7 execution” means in practice * Q&A and open discussion **Lesson 2 — The “How” (step-by-step setup)** * A simple walkthrough of the basic tools you need * Step-by-step guidance to install and prepare the required exchange apps/accounts * A clear checklist to be ready for future sessions (You won’t be left alone—everything is explained calmly and in order.) ### What to bring To make the second lesson smooth, please bring: * **A smartphone** (for authentication and exchange app setup) * **A laptop** (for the setup steps and configuration) If you only have one device, you can still join Lesson 1. The setup lesson is simply easier with both. ### Who this is for * People curious about algorithmic execution and portfolio discipline * Beginners who want a structured approach * Experienced traders who want more consistency and less stress ### Agenda * Welcome + introductions * Lesson focus of the day (Why / How) * Guided walkthrough (where applicable) * Q&A + next steps ### How to find the group * Arrive a few minutes early and look for the **Project Equilibrium** group. * I will be there to welcome attendees if you’re unsure, simply ask the venue staff for the Meetup group name.

**First meetup of the Columbus AI Engineering group.** We’ll kick things off with a practical, beginner-friendly discussion on: **How LLMs like ChatGPT actually work — and how to build real applications with them.** We’ll cover: * what’s actually happening under the hood (at a high level) * why LLMs behave the way they do (hallucinations, prompt sensitivity, etc.) * how people are building real systems with them today * where things break in practice This will be a **short, informal talk (\~15–20 min)** followed by open discussion and Q&A. Whether you’re an engineer, builder, or just curious about how modern AI systems work, you’re welcome to join. No slides, no fluff — just real conversation about real systems. We’ll hang out afterward and get to know each other.

## **Columbus Bitcoin Meetup – Event** Join us for another great evening dedicated to Bitcoin, learning, and community. We will be gathering in the private room at Olentangy Brewery for an evening of conversation, education, and fellowship with fellow Bitcoiners. This special event will feature three guest speakers sharing insights from across the Bitcoin ecosystem. ### **Guest Speakers** **Lindsay Faust** Relationship Manager at River **Andrew Tilmann** CEO of the Midwest Bitcoin Summit **Carlos Estrada** Founder of Coin Vigilante In addition to speaking during the event, Andrew Tilmann will also be available for a meet and greet. This will be a great opportunity to ask questions about the upcoming Midwest Bitcoin Summit, taking place September 23 and 24 at the Columbus Convention Center. ### **Midwest Bitcoin Summit Discount** Early Bird pricing ends **April 1st**, but you can still save **21%** by using the promo code: **COLUMBUS** Use the link below to apply the discount: [https://tickets.midwestbtc.com/affiliate/columbusbitcoinmeetup/event/midwest-bitcoin-summit-2026/?promoCodeTask=apply&promoCodeInput=columbus](https://tickets.midwestbtc.com/affiliate/columbusbitcoinmeetup/event/midwest-bitcoin-summit-2026/?promoCodeTask=apply&promoCodeInput=columbus) ### **Event Details** This will be a three hour event, with speakers beginning just before 7:00 PM. There will be plenty of time afterward for networking, meeting new friends, and continuing the conversation. Food will be provided. We look forward to seeing you there! ***

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 **Abstract** Web Forms gave .NET developers a powerful abstraction for building reusable UI controls long before design systems were a thing. Web Components finally bring that same idea to the browser natively. This session explores how the Web Forms mindset translates into Custom Elements, Shadow DOM, and HTML templates. We’ll examine how Web Components enable design systems that work across frameworks, how they differ from server‑driven controls, and why they’re becoming a foundational layer for modern UI. Whether you’re maintaining legacy apps or building greenfield projects, you’ll leave with a practical understanding of how to apply familiar patterns in a modern, standards‑based way. **YouTube Link** TBA
