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!

Builders, creators, architects, admins, consultants - come one, come all. This one's for you. We're bringing a little friendly competition to the Columbus ServiceNow community while highlighting the cool things people have built on the platform. Five presenters will take the stage to showcase something they've built, solved, designed, or imagined on the ServiceNow platform - and a panel of judges (plus YOU, our amazing audience) will score them live. So basically, America's Got Talent but make it ServiceNow's Got Talent. Bring a notepad if you'd like 'cause you'll definitely be learning something new. Each presenter gets 10 minutes max to wow the crowd with: • A demo • A real-world business solution • A bold idea • A UX transformation • Or a creative use of the platform Judging Criteria: 🏆 Business Value 🚀 Innovation ✨ User Experience This event is about celebrating ideas, sharing knowledge, and showing how ServiceNow can drive both business impact and meaningful user value. Come learn. Come support. Come get inspired. Refreshments and bites will be provided. And maybe next time… you’ll be on stage.

We meet at lunch each week and each meeting follows a fairly organized agenda. First all participants pass their business cards around. Then each member and guest is invited to give a one-minute overview of their company and what is a perfect referral for the week. We always have a 10 minute presentation from one of the members about their business in more detail. And finally we pass referrals. You're welcome to visit. Nobody is ever put on the spot. Bring plenty of cards!

**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

**Summary** Celebrate America's 250th year and the [Columbus Clippers'](https://www.milb.com/columbus) 50th season by watching [Franklin County's](https://en.wikipedia.org/wiki/Columbus_Clippers) best team play the [best game in the world](https://www.brainyquote.com/quotes/babe_ruth_140116) at [one of the ten best](https://www.dispatch.com/story/sports/minors/2025/03/26/huntington-park-voted-top-10-minor-league-ballparks-usa-today-10best-awards/82656048007/) baseball stadiums in the United States in their 2026 home Saturday opener! The first pitch is scheduled for 4:05 p.m. The gates always open an hour before the scheduled first pitch. I'm usually at the ballpark a half an hour before the scheduled first pitch. Clippers' games usually last around two and a half hours. Being a few minutes early will help us secure good seats. **Parking** I personally always like to park in the [McConnell Garage](https://www.google.com/maps/place/McConnell+Garage/@39.9685114,-83.0103938,17z/data=!4m6!3m5!1s0x88388f24145462d1:0x6238c0f0c851ab70!8m2!3d39.9692957!4d-83.0081175!16s%2Fg%2F1jkw6y27y?entry=ttu&g_ep=EgoyMDI1MTExNi4wIKXMDSoASAFQAw%3D%3D). If nothing else is going on in the area, this should be $7. However, I've also seen it be as high as $22. I can't say for certain what it will be for this game, but once I know, I will post in the comments. Alternately, there are other lots in the area you can try which will probably be a few dollars cheaper. [Here is a map](https://img.mlbstatic.com/milb-images/image/upload/q_auto/milb/ernng44ya2xkr4wbheql) of all the garages and lots surrounding the stadium. Keep in mind that many of these are outdoor lots and your car will be out in the elements. If you decide to look for a different lot, I would mildly recommend either the Buggyworks Lot or the Broadbelt Lot, but I have never parked in either of these myself. Although it won't apply for this game, keep in mind that street parking is also free citywide in Columbus on [Sundays and holidays](https://www.columbus.gov/files/sharedassets/city/v/1/public-service/right-of-way-permit/on-street-parking-out-of-service-policy-and-procedure-final-8.15.2022-signed.pdf). **Where We'll Be** Here is a [map of the ballpark](https://img.mlbstatic.com/milb-images/image/upload/milb/qkqohbqjgtx5uwo6zkgn.pdf). We'll be sitting on Level 3 of the [Left Field Building](https://www.milb.com/columbus/ballpark/huntington-park) (aka the "AEP Power Pavilion"), which features a 110 foot bar with six open patios overlooking the field. This area is covered and will be out of any sun or rain that may transpire. If you enter the park through the Center Field Entrance (which is at the intersection of Nationwide Blvd. and Neil Ave.), there will be a door to your immediate right after you enter that leads to a staircase up into the Tower. This door is not well-marked, and if you've never been to Huntington Park before, you may wonder if you're actually allowed to go in and up the stairs. Yes, you are. We'll be on the Tower's "Level 3". I have uploaded to the Photos section of this event page, below, a picture of the sign you want look for after you ascend the stairs, so you'll know you're on the correct floor. **Tickets** Do not buy your tickets ahead of time. They will literally be twice as expensive if you buy them on Ticketmaster. Instead, go to the ticket window near the Center Field Entrance. Buy a *Standing Room Only* ticket (don't worry, you won't be standing), which will cost you a flat $8 with no other taxes or fees. These tickets never sell out, and this is the cheapest way to get into the park. **Carry-Ins** Per the team's [website](https://www.milb.com/columbus/ballpark/a-z-guide): "Soft-sided coolers are permitted in the general seating area [which is where we'll be], but not hard-sided coolers; also no alcohol, glass bottles, or cans will be permitted. SMALL bags or backpacks of food items and beverages in plastic bottles are ok. Reusable water bottles are permitted, but must be empty upon arrival. Diaper bags are allowed." I always bring a disposable plastic bottle of water and refill it as I need at the park. Bottled water at the game is something like 4 or 5 dollars. So if you want a bottle of water, I recommend bringing your own bottle instead of buying it at the park. **Food & Drink** The area we'll be in has burgers, hot dogs, salads, soft pretzels, ice cream, and other sorts of things you would expect at a baseball game. I've posted pics of the menu in the Photos section, below. The burger and fries are $14 plus tax, and they're not bad. (This is what I usually get.) The beer is *really* overpriced. It's like $9, or $20 for a pitcher. If there's some people to help me drink it, though, I'll buy a pitcher of Michelob Ultra. While we'll be on the penultimate floor of the Tower, the top floor (which has a great view, but is fully exposed to the elements) has a [Dirty Frank's](https://dirtyfranks.com/) hot dog stand. I've never gotten anything from there, though I've been told it's good. The Donatos pizza stand is also a very short walk away from where we'll be. I love Donatos, but the pizza is so expensive at the ballpark. It's like $9 for a personal-sized pepperoni. It is good, though. **Peroration** Let's (watch them) play ball!

**New Dojo Location!** **Knotty Pine Brewing** 1765 W 3rd Ave, Columbus, OH 43212 We're going to try a new dojo location for a few weeks and see how it works Dojos are informal Python group study sessions where everyone interested in Python gathers to learn about Python, help others with Python, or just hang out. Everyone is welcome from Python beginners to experts. Bringing a laptop is encouraged (we'll have extension cords and power strips). If there's something you want to learn leave a comment on this invite so we can plan ahead. We're looking for topic suggestions and people interested in presenting at our monthly meetings. To this end we've set up a survey form at [https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc](https://docs.google.com/forms/d/15eBKF1nQQ2XS5gzD4rvhVRHMBEj7lJtHuA9wXupS3Uc)
