**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 longest day of the year is comming and let's another Kotlin meetup. This time we geather at N26! **⚠️⚠️⚠️ Due to a venue policy please submit the following form for additional details. Without it, you won't be allowed inside the venue:** https://forms.gle/XjqVXkD3FARCM6jA8 **Line-Up:** 👉 **TestBalloon: Kotlin testing is easier (and more fun) than you think** *by Oliver Okrongli* You want an easier way to write tests? Parameterize tests in plain Kotlin? Reuse a series of tests? Easily extend own your test setup? Have first-class support on all platforms? All without struggling with a huge framework API? TestBalloon is a new test framework that brings the power of Kotlin to your test setup. With a small-surface API, a hierarchical test structure and an extensible DSL, TestBalloon makes Kotlin testing easy, even at scale. Oliver, the author of TestBalloon, will show testing patterns and strategies and lots of practical examples, ranging from simple unit tests with less boilerplate to advanced testing with coroutines and generated data. This talk is based on insights first presented at KotlinConf 2026 in Munich. At the end of this talk, you’ll be able to firmly the answer the question: "How can I master Kotlin testing with ease, and make my team release with joy and confidence, every time?" 👉 **One Topic to Rule 'Em All** *by Yonatan Karp-Rudin* Kafka delivered every event exactly once, in order, and lost nothing. So what broke? This talk follows that question into the gap most event-driven systems leave open: what actually guarantees the order your domain depends on, and what quietly doesn't. We start from a real log line, find the crack in an architecture that looks clean and ships fast, and rule out the fix everyone reaches for first. The cure turns out to be one sentence of domain thinking plus one line of config, though the Schema Registry will fight you on the way there. A live demo runs the bug and the fix back to back: same load, same hero, one change. If you build with Kafka, you have probably shipped a version of this bug. You will leave able to spot it and fix it before it pages someone. 👉 **TBD** **Speaker Bios:** 🗣 Oliver Okrongli Oliver has been shaping and creating software from backend to frontends. He is the author of TestBalloon, a next-generation Kotlin test framework. Before, he has helped to maintain Kotest, and contributed to several libraries of the Kotlin ecosystem as well as the Kotlin compiler. Can be found on GitHub (OliverO2) and the kotlinlang Slack (Oliver O). When not developing, he is most probably in deep talks, dancing, snowboarding or F18 catamaran sailing whenever he gets a chance. 🗣 Yonatan Karp-Rudin Yonatan Karp-Rudin is a Staff Engineer at Billie, building event-driven systems in Kotlin and Spring Boot. Off the clock, he plays with AI agents and builds random tooling, trying to hand off as much of his own workflow to a machine as he can. The rest of the time he's brewing mead or deep in a video game. **🗣 TBD**

Yes it’s free. But please come only if you are ready. The 22-Strand DNA Activation Used For 3,000 Years To Awaken Human Potential For the first time a high level Initiate reveals the 3.034 year old method to awaken human potential.. this method is available to the public since 1997 and starts reaching the masses now! Humanity is ready! Before that date people like Da Vinci, Tesla, Michelangelo, Pythagoras, Goethe, Beethoven and many more received the private opportunity to study these secrets. There is a moment in every seeker's life when reading stops being enough. You've done the books. The podcasts. The meditation apps. The therapy. Maybe even plant medicine, breathwork, yoga teacher trainings, retreats in distant countries. And still — somewhere quiet inside you — that voice keeps whispering: "There has to be more." There is. For 3,000 years, an unbroken lineage of teachers — traceable back to King Salomon the Wise — has guarded a precise energetic transmission known as the Life Activation. A 22-strand DNA activation that awakens dormant aspects of your divine blueprint. The same activation that has changed the lives of thousands of people across more than 50 countries. On Thursday, in the heart of Berlin, I'm opening the doors for a free 2-hour evening to share what this path is — and what it has done for me. --- What You'll Discover — What the Life Activation actually is (and why every Mystery School student receives it first) — The lineage behind it — King Salomon, 3,000 years, 7 Mystery Schools worldwide — How it works with your chakras, magnetic energy, etheric body, and elemental forces — What people consistently report afterwards: clarity, vitality, release of inherited patterns, deep peace — Why it bypasses the mind entirely — no belief required, no understanding needed — Where this path can take you — Sacred Geometry, Kabbalah, Initiation, Healers Academy — Live Q&A — ask anything --- Who This Is For You belong in this room if you: → Feel stuck despite trying everything — therapy, self-help, coaching, retreats → Sense that there is more to life but cannot quite reach it → Are walking through a major transition — career, relationship, identity, crisis → Want to begin a real spiritual path — not just read about one → Feel drawn to ancient wisdom and lineage-based traditions → Are ready for change. Real change. Not more information. You also belong here if you have zero spiritual background. You don't need to believe in anything. You just need to show up. --- What This Is Not Not a sales pitch dressed as a talk. Not a "manifestation" workshop. Not therapy. Not channeling. Not New Age improvisation. This is ancient lineage work — the same teachings, transmitted the same way, for three millennia. --- Your Host I'm Paul Schulz — Ritual Master in the King Salomon Lineage of the Modern Mystery School, based in Berlin, teaching in English across Europe. I received my own Life Activation in this city, and it changed everything. Now I share this work with seekers ready for the next step. --- The Details 📍 Berlin — see above 🗓 every second Thursday 💶 FREE (limited seats — registration required) 🎙 Language: English 🎁 Bonus: open Q&A --- Reserve Your Seat The question is not whether you have time. The question is whether you can afford to keep living the way you have been living.

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.
