**One week later than usual! We'll be at the small Seminarraum instead of the mainhall.** **BitDevs Bitcoin Socratic Seminar Berlin @ c-base Raumstation** Join us for our monthly interactive **[Bitcoin Socratic Seminar](https://bitdevs.berlin)** in Berlin! We’ll start with pizza and beer (sponsored by [Ordimint.com](https://ordimint.com)), followed by deep-dive discussions on the most interesting *technical* developments in Bitcoin from the past month. Participation by everyone is highly encouraged! Our goal is to foster lively discussion, knowledge sharing, and debate. In the weeks leading up to the event, participants gather topics such as: * New research papers * New BIPs and BOLTs * Network statistics * Technical blog posts * Mailing list and Delving Bitcoin threads * Pull requests and updates from key repos (Bitcoin Core, LND, Core Lightning, Eclair, BDK, rust-bitcoin, LDK, Electrum, …) Each topic is briefly introduced by our moderators and then discussed before moving on. The full list of links will be published at [bitdevs.berlin](https://bitdevs.berlin) 1–2 days before the event — please review them in advance to get the most out of the discussion. **Important details:** * This event is highly technical — best suited for those with a solid grasp of Bitcoin internals. Curious newcomers are always very welcome, but expect in-depth conversations (see the former topics at [bitdevs.berlin](https://bitdevs.berlin)). * Chatham House Rule applies: you may share what was discussed, but not who said it. No livestream, no photos, no recordings. * The evening begins with food and networking; people often stay after the seminar to keep talking. **Co-hosted by:** * [Felix](https://x.com/FelixWeis) * [Freerk](https://x.com/freerko) * [Fabian](https://x.com/fjahr) For background on the idea of BitDevs Socratic Seminars, see [this article](https://bitcoinmagazine.com/articles/op-ed-want-to-learn-about-bitcoin-try-a-local-socratic-seminar).

The Moody Comedy Show is an interactive stand-up experience where the audience sets the tone! Just like in life, we all have different moods—happy, angry, excited, or maybe just “meh”—and comedians are no different. Each performer will embrace their mood on stage, delivering jokes that match their vibe, whether they’re feeling upbeat, frustrated, or existential. But that’s not all—you get to join in too! Audience members will write down their mood, and we’ll pull from a hat, riffing on your emotions in real-time. It’s a comedy show that evolves with the energy in the room https://www.eventbrite.de/e/moody-comedy-showcase-tickets-1276031276899?aff=oddtdtcreator

Welcome to Drunken Philosophy, a casual, curious, social discussion club. Come grab a drink and a seat at The Oracle. **Optional topic for this meetup: Where is everybody?** In 1950 the physicist Enrico Fermi was talking about aliens over lunch and asked a question that still has not gone away: if the universe is so vast and so old, and even a fraction of those billions of stars have planets, where is everyone? By the numbers the galaxy should be crowded with civilizations. Instead we look up and hear silence. That gap between "they should be everywhere" and "we see no one" is the Fermi Paradox. One of the most unsettling answers is the idea of a **Great Filter**: somewhere on the road from dead chemistry to a galaxy-spanning civilization, there is at least one step that is almost impossible to get past. Maybe the filter is behind us. Maybe life starting at all, or simple cells becoming complex, or intelligence ever evolving, is the freak accident, and we already cleared the hard part. Or maybe the filter is ahead of us, and advanced civilizations reliably wipe themselves out before they spread. Here is the part that messes with people. If we ever found life somewhere else, even pond scum on Mars, most people would call it the greatest discovery in history. But it might be the worst possible news. It would mean life is common, the early steps are easy, and the hard step is still in front of us. So the eerie silence overhead might actually be the best sign we could ask for. **Questions to wrestle with:** * Is it better to be alone? Would you rather we find alien life and learn we are not special, or find nothing and quietly improve our odds of surviving? * Where do you bet the filter sits, behind us or ahead of us, and why? * If it is ahead of us, what is it? Nuclear war, climate collapse, AI, something we cannot even picture yet? And can we do anything about a filter we cannot see coming? * Two principles pull opposite ways here. The principle of mediocrity (the Copernican principle, Sagan's "no privileged place in the universe") says we are ordinary, so what happened on Earth probably happened everywhere, which makes the silence scream louder. The anthropic principle says of course we find ourselves somewhere life was possible, since we could not observe anything else, so our being here may say almost nothing about how common life is. Which lens do you trust, and does the silence still demand an answer once you account for observer selection? * And if we did confirm life out there and had to accept we are not special, what would that do to belief in a higher power, and would shedding (or keeping) that belief help or hurt our odds of pulling together as one species? * Does any of this change how you live, or how humanity should be spending its time and money right now? As always the prompt is optional. Come for the conversation, stay for the drinks, and bring your own questions.

Why are we unhappy? Where does emotional pain come from? Studies show that people who suffer from long-term emotional pain have painful experiences in their lives that were never fully resolved in their mind. In other words, there were issues in the past that were not completely dealt with. This can include abuse in childhood, breakups, divorce, death of a loved one, to name a few. How do you know whether you have gotten over something painful? Here is an easy test: Do you still have attention on what had happened to you? For instance, do you still find yourself thinking about something painful that you went through? If you are, then you are not over it. In fact, in severe cases, people find themselves playing a "tape" in their mind over and over again. So how do you heal from your past? How do you stop the "tape" playing in your mind? In this meeting, you will learn a technique to help you with that. Come join us! Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there. This group is created by the Dianetics and Scientology life improvement center.
