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.

**In Association With the Berlin Portrait Academy and PAKD Gallery / PAKD Art Lab** * **www.berlinportraitacademy.com** * **www.pakd-gallery.com/artlab** * **Cost: 15 Euros** A regular opportunity to study the nude or portrait from life for 3 hours, every single week! We have one long pose - you can choose whether to draw several studies from different angles around the room, or take your time to do a single sustained drawing or painting in full detail. The pose is held for 20 minute intervals with five minute breaks in-between so the model to rest and stretch, and so artists can move between seats if they choose. We provide some materials such as paper, pencils & pastels for free. Canvases, brushes and acrylic paint can be purchased at the event. We hope to see you there very soon!

Dear CTO Roundtable Community, I'm happy to share that, outside of our regular event schedule, we're organizing a special CTO Roundtable gathering. This time, we're keeping it simple: **25 seats in a beer garden, no panel, no agenda.** Just a relaxed evening to exchange ideas, discuss challenges, share experiences, and learn from one another as tech leaders. This special event is made possible thanks to our sponsor, **Stephan Schmidt**, founder of **[AmazingCTO](https://www.amazingcto.com/)**. Thank you, Stephan, for making this gathering possible. We're looking forward to spending a summer evening together with great conversations, technology leadership discussions, good drinks, and valuable connections. **Spots are limited to 25 participants**, so be sure to reserve your place early. We hope to see you there! Best regards, Christoph

**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! 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**).

Hola chicos, Moin zusammen, lasst uns Deutsch und Spanisch sprechen und ein paar Bier zusammen trinken, die Idee ist einfach und gut :) Bitte bringt zumindest basis Deutsch oder Spanisch Kenntnisse mit! Vamos a hablar español y alemán y tomar unas cervezas, la idea es simple y buena jaja. ¡Por favor, ven por lo menos con un nivel básico de español o alemán! Danke, gracias!

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.

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.
