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.

Salut les amis, Nous vous invitons pour notre prochaine discussion **le mercredi à 19h00**, **au Dussmann KulturCafé**, au 2e étage de Dussmann das KulturKaufhaus Berlin, Friedrichstraße 90, 10117 Berlin. Nous espérons voir de nombreux nouveaux visages et avoir une discussion animée et inspirante ! ✨ **Au programme ?** Des échanges captivants sur des sujets de **philosophie** et de **société** qui nous intriguent et nous passionnent. Une belle occasion de partager nos idées, découvrir d’autres points de vue et apprendre ensemble dans une ambiance conviviale. Ce soir, Azzeddine El Matine présentera son nouveau livre, Abgewickelt, une fiction philosophique qui raconte l’histoire d’un jeune Marocain de Casablanca subissant les conséquences de l’arbitraire et de l’oppression d’un État corrompu, et qui aspire à commencer une nouvelle vie dans le GDR. **Niveau de français** : Idéalement, il vous permet de participer à une discussion intellectuelle sans trop de difficultés ! **Lieu** : Friedrichstraße 90, 10117 Berlin Si possible, nous vous demandons une petite contribution de 2 euros afin de couvrir les frais de Meetup. À bientôt! 😊

**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).

Hello! We are the team at CaféIN, an inclusive café in Berlin, and we are launching a new Walk & Talk series. Together, we will discover an “alternative” side of Berlin: not the Berlin of clubs, nightlife and the city’s usual clichés, but a greener, calmer side shaped by local neighbourhoods, green spaces and places beyond the typical tourist routes. ❤️🌳🏡🏙 The idea is simple: to bring people together through walking, good conversations and shared experiences. Whether you are new to Berlin, looking to expand your social circle or simply want to spend a relaxed Saturday outdoors, everyone is welcome. 😎 How it works: • We meet at 12:00 in front of Rathaus Spandau. [https://maps.app.goo.gl/r1gZtMxX1nmWrzuT9](https://maps.app.goo.gl/r1gZtMxX1nmWrzuT9) • We walk through Spandau’s Old Town and continue towards Johannesstift. • Along the way, we will explore parts of Spandauer Forst, one of Berlin’s largest urban forests. • We finish the walk at CaféIN, our inclusive café located on the green Johannesstift campus in Spandau. [https://www.instagram.com/cafein_johannesstift/](https://www.instagram.com/cafein_johannesstift/) This will be an opportunity to continue conversations over coffee and discover a unique place that brings together culture, community and inclusion. The event will last around 3 to 4 hours, but everyone is free to leave earlier or stay longer. Please wear comfortable shoes and check the weather forecast beforehand 😜 This is a relaxed social event and everyone is responsible for themselves during the walk 😇

Der politische Diskurs ist für alle diejenigen, die politische und gesellschaftliche Themen verfolgen und sich gerne darüber austauschen wollen. Wir alle wissen, dass der Vorteil einer Demokratie gegenüber autoritären Systemen darin besteht, dass Meinungen geäußert und Kritik geübt werden kann - so let's do this! Jedesmal steht ein neues, eher generelles Thema im Zentrum, über das wir uns respektvoll austauschen wollen. Im kommenden Abend geht es um die von der Rentenkommission eingereichten Vorschläge zur Rentenreform. Interessante Informationsquellen für: [Nationale_Politik](https://www.deutschlandfunk.de/podcast-106.html), [News_aus_Wirtschaft](https://open.spotify.com/show/0MqROiCw2Vl0aVqxWdPjRC?si=dioN4162TqytZm210rXpYw), [Internationale_Nachrichten](https://ground.news/) **WhatsApp Gruppenchat**: Regt dich ein Politiker / eine Argumentationslinie auf? Hast du einen Podcast gehört, den du unbedingt teilen und mit anderen besprechen willst? Möchtest du aktiv bei der Themenwahl unserer Diskussionsabende teilnehmen? Es gibt eine Whatsappgruppe. Sprich mich gerne auf einem Event an, dann füge ich dich hinzu. Wir freuen uns auf deine Ansichten! Photo by iStockphoto/Thinkstock

**The direction is set. Now let's build.** Our first session shaped what this group is about, now we get to see it in action. A member is showing off a real project: what they built, what broke, and what surprised them. Then we open it up: Q&A, war stories, and a honest conversation about the tools, lessons, and struggles we're all running into. Come ready to dig in and share. Before you arrive, **sign up for our newsletter** to stay in the loop on session recaps, resources, and upcoming events: [Future-Club](https://future-club.org) Show up ready to contribute. 🔥 See you there! 👋

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.

📆 Agenda * 19:00 Welcome to the PUB (Python Users Berlin) – setting up * 19:15 Main talk * 20:00 Lightning talks * 20:30 Social gathering 🎙 Main talk by [Sam Bail](https://www.meetup.com/de-DE/members/57634242/): PySpark PySpark is a powerful library that brings Apache Spark’s distributed computing capabilities to Python, making it a key tool for processing large-scale data efficiently.

**Practical Curiosity: Learning from Everyday Data** How do we actually get better at utilizing our day-to-day data? Fancy dashboards and complex models might look nice and draw attention, but that’s not where most of us spend our time. In fact those shiny outputs frequently sit unused, while the real insights are drawn from the analyst’s daily practice. Sometimes it’s as simple and as powerful as noticing that a segment is shrinking, a channel is underused, or certain links keep getting all the clicks. There’s many different places that the spark of insight can come from, but you have to keep your head in the data and know where to look. In this session, we’ll explore real-world examples of how segmentation, testing, and click behavior can uncover practical digital marketing opportunities. You’ll leave with inspiration for your own use cases, along with a few simple ways to ask better questions, spot meaningful patterns, and make smarter decisions without overcomplicating it. **About Our Speaker:** [Elaine Armbruster](https://www.linkedin.com/in/elainearmbruster/) is a Director of Digital Experience at the [American Diabetes Association](https://diabetes.org/), where she focuses on using data and insights to create smarter, more effective digital experiences. A lifelong Columbus resident, she has built her career in email marketing and the broader digital user journey, and is finding she most enjoys working in the messy middle where systems, data, and big ideas don’t quite line up yet.

You can sleep in on the Sesquicentennial (observed), we’re shifting to the following Friday. But join the local UX community for a chat and some biscuits to catch up. If you were in CA for Figma Config, tell us all the lines and you can tell me how I can animate an SVG without coding it by hand, and why I’d even want to. Thanks to the team at Nationwide of supporting the group.
