Hello! I’m organising a coworking + socialising session for all of us who are working on projects (e.g. our own creations, freelance or remote work) but don't feel like sitting alone at home. 🙂 To ensure that we have time for both socialising AND working, we will be using the so-called “Pomodoro” technique: **50 mins deep work** (silent), followed by **10 mins break** to socialise. And then repeat! You are welcome to join whatever your personal background is, and whatever project you are working on. I (the host) speak English and German, so either language is fine. ——————————————————- AGENDA: * **Short Intro** Tell us who you are and share something about what you will be working on today * **Pomodoro Session** \- 3x \(3h\) Each Pomodoro session consists of 50 mins focused “deep work” (no talking, no interruptions, **phones on silent mode**) -> then 10 mins break: a chance to share your progress with others -> Repeat * **15 mins Wrap Up** Celebrate what you achieved and get to know others 😊 ———— Wifi + power plugs are available - but best to bring a fully charged laptop, just in case 🙃 You **do not** have to pay anything. But since we are using the café space, it is common courtesy to buy at least one drink (coffee costs roughly **4 Euros**).

On the 1st of July we will host the next iteration of our monthly Audio Developer Meetup where **Peggy Sylopp** from [sinceare](https://www.sinceare.com/) will be presenting her work on personalization approaches for hearables, and **Vlad Litvinenko** will demo 'Spotykach', a looping playground. See below for details! As always, there will be a chance to network over drinks and pizza. Anyone interested in Audio development is welcome! Doors open at 18:00, talks start at 18:15. Please note: Attendance is **strictly limited** to people who have RSVP'd. Talk details: **Can users train their own audio system?** \- Peggy Sylopp In this talk, we present Sinceare’s closed-loop personalization approach for hearables. Instead of relying on predefined fitting rules or static presets, users teach the system how it should sound through interaction and feedback. These preferences are transformed into personalized machine-learning models that learn how to control existing audio processing algorithms according to individual preferences. Rather than replacing audio DSP algorithms, the generated models act as an adaptive control layer that continuously adjusts algorithm parameters based on user-specific listening preferences. Based on more than eight years of research and a recent study conducted with Fraunhofer IDMT and Charité, we will share insights into user-driven audio model generation, human-in-the-loop machine learning, and the path from research prototype to future embedded hearable deployment. **Spotykach, a looping playground** \- Vlad Litvinenko Vlad is a Berlin based software developer doing e-commerce by day, bleeping machines at night and sometimes music in between. The talk is about device they’ve recently built. It’s “Spotykach”, a looping playground, as they call it. It started from an attempt to do a simple Beat-Repeat kind of plugin, but then evolved into a community project within Synthux Academy with people from different backgrounds and countries.

**This is 100% non-profit. The 15€ sign up fee for everyone is only to minimize last-minute cancellations. The total sum goes to a bar-tap that everyone can use to order drinks until the amount is used up. ‼️NO REFUNDS‼️** **‼️Please don't just show up without RSVPing here and paying the 15€. We have a separate room that has limited capacity and a specific drinks agreement with the bar - so splitting up the bill won't become a mess.‼️** **Small update on how your money get's used from May 2024 onwards:** As of this month, meetup.com has started charging me 34€ instead of 16€ per month. I've decided to distribute this fee evenly among all us participants every month. Example: In the last 12 meetups, the average number of attendees was 17. With 17 attendees I would effectively collect 230€ (after fees). I would now substract 34€ leaving us with 196€ that go to the bar. 15% get's tipped to the wait staff, in this case 30€, leaving us with 166€ effectively to order drinks. Hope everyone is cool with this system. :) Website: https://www.pberg-engineers.me WhatsApp groups: Please come and join us on WhatsApp! \- "PBerg Engineers \- NEWS" \- Only organizers can post announcements or polls \-\> https://chat\.whatsapp\.com/EqMJMmlCZO6LOOfAoG4yTj \- "PBerg Engineers \- DISCUSS" \- Everyone can post \-\> https://chat\.whatsapp\.com/LPuo76J83gF6IZMLUcM4u2 Please join those groups now if you're interested. :) All skill/education-levels welcome! :) Lightning Talks: \- TBD We'll also have a brief "Jobs: Lost & Found section". **Location:** From the street you will have to enter the right hand Cafe Chagall (yes, there are 2).

This talk walks through a practical demo of automating the full SRE lifecycle: from incident investigation to deployment validation, using Grafana MCP and the GitLab Agent Platform, and where humans still need to stay in the loop. *Serhii Vasylenko* **The Pipeline Was Green — AI Agents and CI Trust** We’ve spent years building CI/CD pipelines that tell us when code is "technically correct," but are they capable of telling an autonomous AI agent if a change is safe to apply? This talk explores a real-world incident where an AI-powered automation -- pairing Renovate with Claude Code -- successfully executed a "green" pipeline that broke a critical QA cluster for three days, how the team reacted, and how we evolved our vision toward the future of human-agentic collaboration with code. *Frithjof Hoffmann* **Managing Uninvited Guests: Securing Open Source Dependencies** Open source software is the ultimate neighborhood party, but what happens when an uninvited guest slips through the door? This talk digs into the messy reality of dependency hell and its role in software supply chain security: from typosquatting attacks to maintainer account takeovers, and the abandoned projects with known CVEs quietly living in your codebase rent-free.

Columbus Code & Coffee is an inclusive, informal co-working session. People of all skill levels attend, and we love it that way. Many people (optionally) bring projects to work on, and many other people (optionally) socialize the entire time. It's entirely up to you! **What to Expect at the Intro Circle** \~\~\~\~\~\~\~\~\~\~\~\~\~ Near the beginning of the event (1:30 pm), we do a standup: * Organizer announcements, updates, and logistics Round 1 - (7 secs max): * Your name * What you're working on * What you can help others with Round 2: * Community events you wanna plug. If none, that's cool too. Round 3: * Job opportunities you're hiring for OR announce that you are looking for one. If none, that's cool. After the introduction circle, everything is self-organized! Feel free to work alone, pair up, attend one of our workshops/presentations, or mingle!

Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on. That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable. In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork. This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it. We’ll cover: * Why “it looks good” is not enough * How to improve prompts by changing the input, context, and constraints * How to compare LLM outputs more systematically * Basic evaluation techniques for accuracy, consistency, and usefulness * How embeddings, cosine similarity, and scoring can help evaluate results * Where automated evaluation works — and where humans still need to stay in the loop By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.

We're planning a hands-on technical session focused on building AI solutions in ServiceNow - think skills, agents, and real-world use cases. If you’re curious about AI on the platform, RSVP now and stay tuned for more details. Let's build together!
