Session 20: Memory
Session 20: Memory
Hi! Welcome to Thought Experiments in Pubs - Berlin edition, where you get to have deep conversations with people you've never met. The topic will be "Memory". I'll post the questions that will guide us through that topic here on the day as a comment. **Location:** [Atopia Kaffeehaus, Prenzlauer Allee 187, 10405 Berlin](https://maps.app.goo.gl/Ukuup9CTrmedrB6f9) \*Please consider that the locations we visit do not charge us for our booking, so in return, please make sure to show your appreciation by buying drinks or snacks. * If you're signed up but can't make the event, please cancel so someone else can take your spot \*Make sure you check the right address, there is a sister pub nearby and it's not that one ☝️ **The idea:** A chance to meet and talk at a 'deeper' level, and skip the 'small talk'. **How will it work?** We will have a set of 'Thought Experiments', short, philosophical scenarios and questions, which will be discussed in groups. The conversation will flow freely, there are no strict rules, simply share and discuss your perspectives on the given topic. The thought experiments will be posted here ahead of the event. **Who should come?** Everyone! We believe that the more perspectives, the richer the conversation. This group is not about being experts in philosophy, it is about *doing* philosophy. That is, bringing our various life experiences and lenses on the world to group discussions about the human experience, the nature of reality... etc. **Do I need to bring anything?** No! Just an open, inquisitive mind. We will do 3 rounds of discussions. After the event, I would love to hear your feedback on the session. The thought experiments we will discuss are around the theme of the day. Prompts will be posted here on the day of the event. See you soon! \- Dirk *Thought Experiments in Pubs Berlin is inspired by [Thought Experiments in Pubs London](https://www.meetup.com/thought-experiments-in-pubs/), which originated in 2023 as a social experiment to get people together to connect at a deeper level.

#34 AI Series: HuggingFace - G. Channing
#34 AI Series: HuggingFace - G. Channing
We are excited to feature **Georgia Channing**, who is currently leading the AI for Science team at **Hugging Face** and will discuss "**When Silicon Meets Carbon: Bringing Synthetic Biology to Life**", lasting approximately 45 minutes. After the talk, seize the opportunity to connect with fellow AI enthusiasts to share ideas and questions while enjoying free drinks and pizza. **Door close by 7.15pm, so please come early! Also, "attend"ing (RSVP) here on Meetup is strictly necessary to be guaranteed entry.** Please note that Meetup has recently been quite keen on promoting its Plus program. However, you are not obligated to purchase it, as both our events and the platform remain free. **Who is this event for?** This event is open to everyone interested in state-of-the-art AI research. We especially design it for students, PhD candidates, academic researchers, and industry professionals with a research focus in machine learning. **Abstract**: Foundation models have transformed how we read and design biological systems, from protein structure prediction to the generation of novel sequences. But building these models is as much an engineering problem as a scientific one. This talk looks at what it takes to bring AI for biology from research into practice, and at the challenges that make science a uniquely demanding domain for machine learning. We will cover how foundation models for biology are trained and deployed at scale, why scientific data is so different from the text and images that drive mainstream AI, and where the gap between a benchmark result and a real biological discovery still lies. The aim is to show how modern AI connects to living systems, and what we need to get right for synthetic biology to fully benefit from it. **Bio**: Georgia Channing is the AI for Science Lead at Hugging Face, working at the intersection of machine learning and the natural sciences. She read for her Master’s and PhD in computer science at the University of Oxford, with a focus on applying AI to scientific discovery. Her work has spanned a wide range of AI-for-science areas, including remote sensing, biophysics, and materials design. She now focuses on building open tools, models, and communities that make scientific research more accessible, collaborative, and reproducible. We are [BLISS](https://bliss.berlin/) e.V., the **AI** **organization** in Berlin that **connects like-minded individuals** who share great interest and passion for the field of machine learning. This summer 2026, we will, again, host an exciting speaker series on site in Berlin, featuring excellent researchers from cohere, ETH Zürich, University of Oxford, HuggingFace, and Stanford University.

Sonne & Tiefe
Sonne & Tiefe
Tolle Berlinerinnen und Berliner, als ich schreibe, sitze ich im Wald zwischen Buchen und Eichen auf meinem Campingstuhl und genieße die Ruhe des Sonnenlichts. Suchst du nach Freiheit von dem Lärm der Szene, Lärm der Stadt? Möchtest du Brücken mit interkulturellen, diversen Leuten aufbauen? Dieses Jahr möchte ich unbedingt neue Leute, die Tiefe und Empathie haben kennenlernen. Diesen Leuten meine Zeit geben, und gegenseitige Freundschaften hoffentlich aufbauen. Selbst glaube ich, dass Mädels und Jungs einander nicht verstehen können, wenn der Sinn von einer Person 100% einer Geschlecht ist und die Person keines der Geschlecht gegenüber kennt. Idealerweise sollte der Sinn 50/50 weiblich/männlich sein, dass wir uns gegenseitig ideal verstehen können. Selbst bin ich Künstler, der sich für Farbphysik (Colour Phenomena) interessiert. Zum Beispiel ein roses Kirschbaum in der blauen morgen Stunde. Oder blaue Bäume im Licht eines bedeckten Sommer Tag, auch wenn jeder glaubt, dass man sachlich weiß, ‚Bäumen sind grün!‘ Colour sind, glaube ich, hauptsächlich weibliche Phänomene. Und als Künstler empfand ich seit langem eine Affinität für Colour. Das Bild oben ist ein Kunstwerk von mir. Ich möchte die ruhigen Leuten erreichen, also der Treff ist entweder Online, per Signal Messenger (Link zur Gruppe im Kommentar; nur für Teilnehmer der Veranstaltung sichtbar) um neue Verbindungen leicht zu machen, oder auch sogar besser persönlich, wenn du dich spontan unterwegs sein will und persönlich treffen will. Wenn du mich persönlich triffst setzen wir uns auf eine Wiese, eventuell in der Wuhlheide, oder auf dem Tempelhofer Feld. Schick mir eine Nachricht vorher per Signal Gruppe und wir können uns vereinbaren. Dieses merken: Bitte rauchen Sie bei dieser Veranstaltung nicht. Ich freue mich neue Leute kennenzulernen! Mit geschmackvollen Grüßen, Duncan

Meetup #13 — Money + taxes
Meetup #13 — Money + taxes
The state deals with a lot of money. People and organisations need to declare, file, and pay taxes or receive returns if they overpaid the state. Tax contributions amount to billions of euros, funding public goods such as infrastructure, education, social welfare, and defence. In the 13th edition of our meetup series, we take a closer look at research and design in public finance and taxation, exploring diverse perspectives from 3 speakers. The evening aims to spark a discussion about the government’s or the state’s role, and how it can be accommodating to citizens, residents, and business owners. We will hear from: * Manuel Großmann (Taxfix) * Merici Vinton (formerly US Digital Service) * Sonja Wilczek (DigitalService des Bundes) The federal government’s DigitalService is hosting the meetup on the mezzanine floor of its Kreuzberg office. All presentations will be given in English. Questions in the later discussion part can be raised in either English or German. The event is jointly organised and hosted by CityLAB Berlin and DigitalService.

BLISS x juna.ai Workshop: Open-Ended Algorithm Discovery with LLMs
BLISS x juna.ai Workshop: Open-Ended Algorithm Discovery with LLMs
**⚠️ IMPORTANT: REGISTRATION MANDATORY ⚠️** Registration on **Luma** is **REQUIRED** to attend this event. **Link: https://luma.com/7zfk3orp?utm_source=meetup** Your registration is subject to host approval. You must complete the registration process on lu.ma to receive the full event location details and confirmation of your attendance. **Please note: Without approved registration on Luma, you will NOT be able to access the event location or attend.** We are excited to host a **BLISS x juna.ai workshop** featuring **Dr. Nima Siboni (senior RL Engineer)**, who will guide us through an interactive session on algorithm discovery with LLMs. **​​​ Title: The Heuristic Scientist: Open-Ended Algorithm Discovery with LLMs** **📅 Date: 03.06.2026** **🕕 Time: 18:00** 📍 Location: TU Berlin Marchstrasse 23 [Room 0.011] ​​​The session will last around 2 hours, followed by a networking session with juna.ai and fellow AI enthusiasts (and free pizza!🍕). Bring your laptop! **​Abstract:** Large language models are increasingly useful not only for writing code, but for exploring the space of possible algorithms. In this hands-on workshop, we will look at how LLMs can act as “heuristic scientists”: generating candidate strategies, turning ideas into executable code, testing them against concrete objectives, and refining them through feedback. The workshop centers on the general discovery loop behind LLM-assisted heuristic generation. Participants will learn how to structure problems for algorithm discovery, prompt models to propose interpretable heuristics, evaluate those heuristics with simulations or benchmarks, and use the results to guide further search. We will also discuss when simple prompting is enough, when training or fine-tuning may help, and how to keep generated heuristics understandable, testable, and auditable. ​By the end of the session, participants will have built a small discovery loop of their own and will understand the practical trade-offs involved in using LLMs for open-ended algorithm discovery: creativity versus control, exploration versus verification, and automation versus human judgment. ​ **⚡ FINAL REMINDER ⚡** **You MUST register and be approved on Luma to attend. The event location will only be visible after your registration is confirmed by the host. Link: https://luma.com/7zfk3orp?utm_source=meetup** *** We are **BLISS e.V.**, Berlin’s AI community connecting like-minded individuals passionate about machine learning and data science.

"Ein Teil von mir will rechts wählen" Gespräch mit Linda Ngono zum Buchprojekt
"Ein Teil von mir will rechts wählen" Gespräch mit Linda Ngono zum Buchprojekt
**(Event in German) Bitte beachtet, dass wir auf verschiedenen Wegen einladen, es werden also mehr Menschen teilnehmen, als ihr hier seht.** In unserem neuen Format „Help me think about this“, reden wir mit Forscher\*innen, Autor\*innen und anderen Kreativen über das Werk, an dem sie gerade arbeiten. So bekommen wir spannende Einblicke in ihre Arbeit, und sie erhalten zusätzliche Perspektiven und Impulse aus unserer Diskussion. ***Worum geht’s?*** Linda Ngono ist Psychologin und Psychotherapeutin in Ausbildung und arbeitet gerade an zwei Buchprojekten: An einem belletristischen Buch (für das sie das Arbeitsstipendium deutschsprachige Literatur 2026 erhalten hat) und an einem Sachbuch, über das wir in diesem Event sprechen wollen. Darin schreibt sie über die Frage, wie wir mit Anteilen in uns umgehen, die wir selbst problematisch finden, insbesondere wenn wir uns bei menschenfeindlichen und rassistischen Gedanken erwischen. In unserer Diskussion tauchen wir in Lindas Thesen ein und denken gemeinsam über zentrale Fragen nach: * Wie gehen wir mit Gedanken um, die nicht in unser Selbstbild passen? * Ist es wichtig, problematische Gedanken öffentlich zu besprechen, oder gibt es gute Gründe, bestimmte Dinge nur mit uns selbst auszuhandeln? * Erlaubt uns ein anderer Umgang mit unseren eigenen unliebsamen Anteilen, einen anderen Umgang mit gesellschaftlichen Problemen? * und viele mehr … Die Diskussion wird wie immer mit unseren experimentellen Methoden moderiert, die uns erlauben, das Gespräch fokussierter, entspannter und inspirierender zu gestalten. **FAQs** ***Was kann ich von dem Event erwarten?*** Jede Veranstaltung ist ein Experiment, daher ist es schwierig, genau vorherzusagen, wie sie verlaufen oder sich anfühlen wird. Wir versuchen in jedem Event eine entspannte und anregende Atmosphäre zu schaffen, in der wir verschiedene Aspekte und Perspektiven des Themas gemeinsam erkunden. Zu Beginn der Diskussion werden wir spezielle Spielregeln einführen, die das Gespräch langsamer, aber auch fokussierter und klarer machen sollen. ***Für wen ist dieses Event gedacht?*** Diese Veranstaltung richtet sich an alle, die sich für das Thema und/oder das Konzept interessieren. Wir möchten einen Raum schaffen, in dem sich Menschen jeden Alters, jeder Identität und jeder Herkunft willkommen fühlen. Du musst nichts vorbereiten, keine starke Meinung haben und auch nicht extrovertiert sein, um teilzunehmen. ***Muss ich aktiv mitdiskutieren, oder kann ich auch nur zuhören?*** Es ist völlig in Ordnung, nur zuzuhören. Du kannst jederzeit selbst entscheiden, wie aktiv du sein möchtest, und wirst, abgesehen von einer kurzen Namensrunde, nicht aufgefordert, etwas zu sagen. Möglicherweise gibt es jedoch Kleingruppen-Phasen, d. h. kurze Abschnitte, in denen alle Teilnehmer\*innen in Gruppen von 2-3 Personen diskutieren. Du musst daran nicht teilnehmen, sondern kannst die Zeit stattdessen für eine Pause nutzen. ***Wie lange dauert die Veranstaltung?*** *Die Veranstaltung dauert zwischen 1,5 und 2 Stunden. Danach gibt es noch die Möglichkeit, sich bei Snacks auszutauschen.* ***Ist der Veranstaltungsort rollstuhlgerecht?*** Die Veranstaltung ist mit dem Rollstuhl zugänglich, aber es gibt leider keine rollstuhlgerechten Toiletten. ***Was ist das "Diskussions Experiment"?*** Das Diskussionsexperiment ist eine Veranstaltungsreihe, in deren Rahmen wir kontinuierlich Methoden testen, die sinnvolle und inspirierende Gruppengespräche ermöglichen. Unter anderem experimentieren wir mit Techniken, die Diskussionen verlangsamen, Klarheit fördern und die Teilnehmer dabei unterstützen, besser Gehör zu finden. Weitere Informationen findest du auf unserer Website. Dieses Projekt wird von Maria Scholze und Igor Don organisiert.
Nerds, Creatives & Dreamers
Nerds, Creatives & Dreamers
**Nerds, Creatives & Dreamers** is a small, curated gathering in Berlin for two kinds of people who almost never end up in the same room: the ones who build things with code, and the ones who build things with imagination. Developers and painters. Engineers and writers. Founders and photographers. In daily life these worlds rarely collide — here, that collision is the whole point. Just a good space, a deliberate mix of curious people, and the freedom to let the evening unfold. Come ready to be surprised by who you meet and where the evening takes you. A room full of curious humans. We’re here to socialize as human beings. And if you do exchange contacts — make it personal, not transactional. **🛠 If You Build Things** · Developers & Engineers · Designers & Product People · Founders · People Who Code for Fun **🎨 If You Create Things** · Writers & Journalists · Photographers · Artists & Painters · Anyone With a Side Obsession 👉 **You can also join via Luma if this event reaches capacity: https://luma.com/0y2yd2q4** Please RSVP “yes” only if you can make it, so we can save a seat for you and others on the waitlist. **📝 Note:** You are welcome to attend our social meetup! The event is free. The space is generously hosted for us — the only thing we ask is that you support it by buying a drink, etc. A small gesture that keeps evenings like this possible. **🤝 Community:** This is a space built on curiosity and respect. We keep it that way — for everyone.

Agent Gateway Deep Dive with Christian Posta
Agent Gateway Deep Dive with Christian Posta
From APIs to Agents: Control, Identity, and What Breaks Along the Way Most of what we've built over the last \~15–20 years assumes a static frame of reference: Apps talk to services over APIs. You know who's calling what, you can stick a gateway in front of it, apply some policy, and move on. Agents don't really fit that model. They don't just call an API and return. They decide what to do, call a tool, look at the result, call something else, maybe involve another agent, loop through an LLM a few times… all the while, doing onbehalf of the user, with permissions that aren't always obvious. It's not always clear who is actually doing something. It's not obvious what the full execution path looks like. And the access control models we're used to — user → service, service → service fall part. We'll dig into what actually breaks when you start wiring agents into real systems, especially around identity and access control. Things like: \- how \(or if\) you assign identity to an agent \- what it means for an agent to act "on behalf of" someone \- how you enforce policy when the flow isn't predefined \- and how you get any kind of visibility into what just happened We'll also look at some of the patterns starting to emerge: agents talking to other agents, tools being invoked dynamically, and why a mediation layer (ie, agentgateway) must be built from the ground up with this in mind. \-\-\-\-\-\- Speaker \-\-\-\-\-\- Christian Posta (Solo.io) Christian is a globally recognized expert in cloud-native architecture, service mesh, and distributed systems. As Global Field CTO at Solo.io, he works with enterprises to design and implement next-generation platforms—and is now at the forefront of AI-native infrastructure and agent systems. \-\-\-\-\-\- Who should attend? \-\-\-\-\-\- This meetup is for people who are building or thinking about the next generation of enterprise systems: Platform engineers and architects, Cloud-native practitioners, AI engineers working with agents and LLMs, Anyone exploring how AI changes system design \-\-\-\-\-\- How to join \-\-\-\-\-\-\- This time, the meetup will be in the premises of Riverty in Kantstrasse 17, Berlin (4th Floor of Living Berlin mall). Riverty will provide pizza and drinks. Please bring your ID as you will need to sign an NDA (we are a regulated entity).

Drunken Philosophy: Are you really who you think you are? What is the "self"?
Drunken Philosophy: Are you really who you think you are? What is the "self"?
I have been studying the question of "self" online with Prof. Ellie Anderson and so I thought a prompt on the "self" might be interesting. Full confession: I had Claude create this prompt and I like it, so here goes: Imagine a thought experiment that merges two classic puzzles: > You undergo a procedure, performed neuron by neuron, in which every biological component of your brain is replaced with a functionally identical synthetic substitute. At each step, your behavior, memories, and personality remain unchanged. When the last neuron is swapped, is the consciousness experiencing the world still you? And — more pressingly — was there ever a continuous "you" to begin with? ### Questions to Wrestle With * If consciousness is purely physical, does the *gradual* nature of the replacement matter, or is it equivalent to being destroyed and rebuilt? * Could there be a "self" without continuity of experience — even moment to moment, while you sleep? On a more practical level, consider the simpler case first: **hemispherectomy** patients — people who have had an entire cerebral hemisphere surgically removed — often retain a strong sense of personal identity and continuity. This suggests "you" are not rigidly tied to specific physical material. But does that vindicate the synthetic neuron case, or merely show that identity is more *flexible* than we thought — not that it can survive *complete* substrate replacement? I used Claude so I could get this out today and let everyone have some time to consider it. Hope to see you at the Oracle. Sorry about the location change two weeks ago. That's what I get for trusting local weather predictions!
Free In-Person Meeting: Get Over Losses & Betrayals, Build Lasting Relationships
Free In-Person Meeting: Get Over Losses & Betrayals, Build Lasting Relationships
This is a free, in-person meeting on the subject of betrayals, losses and how to get over them so you can build lasting relationships. Burdened by a stressful relationship? Unhealthy relationships can trigger feelings of anger, despair or self-doubt. They can create dwindling spirals of fights and seeking to make-up, or trying to “pin the blame” on someone or something. If you don’t find the RIGHT reasons, or select the correct sources of the problem, the problem can just get worse and worse. Whether in love or personal ties, with friends or at work, our life really IS affected by the quality of our relationships. Good ones can promote pleasure and survival while less optimum ones can lead to annoyance, anger, self-doubt, stress, or even affect our health and ability to survive well. Whether you are suffering from a divorce, or a painful break-up, don’t know who to trust (or who to CHOOSE) as a partner, friend, boss or employee - the anxiety of relationship troubles can really make a mess of things. Maybe you’ve suffered a betrayal, or are dealing with hostility or criticalness or invalidation. Dwindling relationships can involve destructive behavior, where we hurt those we love, or start succumbing to self-destructive thoughts, attitudes or behaviors that spiral out of control and affect much more than our immediate relationship. Past losses in love or life can affect how we act or react to new people and situations and hold us back from even starting to create new, possibly great relationships! How can one get back onto a saner course of action? Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life: human relationships! Break free from self imposed limitations Here we will discuss: • How to “erase” the trauma of past hurts and betrayals so that one isn’t always repeating past mistakes. • Why and how do the negative emotions of others affect you? • Why is my partner withdrawing and what can I do about it? • Why do we sometimes feel compelled to hurt the ones we love? • Fights & arguments - what's really behind them? • What underlies “corrosive criticism” or the need to invalidate self or others? • How one can stably change one’s outlook on life so they can affect positive change? • Where do compulsive destructive behaviors come from and what can be done about them? • How to form closer bonds & keep growing the relationships with the people you care about? • How to enhance one’s own ability to survive and create positive healthy relationships whether in love, family & friendships or in work, business or one’s career? Relationships can be hard and life itself IS challenging. Why not arm yourself with the knowledge and breakthroughs that have been made about the mind, mental reactions & interpersonal relationships, so that one has better awareness and control over themselves and life in general. Learn where painful experiences are “stored” and how they can unknowingly affect us. You will also find out how one can “erase” those past painful experiences so that one is free to move forward without being tripped up by the past. Learn too, about what can lead some people to become “toxic” personalities and how to identify those traits in others so you won’t be tripped up trusting the wrong person. Our free Meet-ups occur in a safe environment where one can learn, without fear of judgment or criticism, and without the recommendation of harmful mental techniques or therapies, just how YOU can get yourself onto a happier & more successful path: in love & in life. We look forward to having you join us! This class is sponsored by the Dianetics & Scientology Life Improvement Center of Central Ohio.

Stop Guessing: A Product Person's Guide to AI Adoption
Stop Guessing: A Product Person's Guide to AI Adoption
## 🤝 Host Information A co-hosted event by ProductTank Columbus & Women in Product Columbus 💡 About the Workshop AI adoption is stalling across organizations — not because of a lack of motivation or tools, but because it's fundamentally a behavior design challenge. This hands-on workshop applies proven Behavior Design models and methods to help you move from a vague organizational wish to boost AI adoption to 3-5 concrete, testable interventions you can act on starting tomorrow. Whether you're a product manager, on a product team, or just someone trying to get AI to actually stick at work, you'll leave with a clear picture of what's worth focusing on, what to ignore, and how to drive real, sustained adoption — no guesswork required. 🛠️ What to Bring Laptop: Fully charged and ready to go. AI Assistant: Have your favorite AI assistant pulled up. (Dom will be using Claude, but feel free to use whichever assistant you prefer!) 🍕 Logistics & Perks Food & Drink: Pizza and drinks provided! Parking: Plenty of free spaces available on-site. ###
