**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).

Layoffs, longer job searches, and rapid shifts driven by AI are leaving many professionals wondering about their next move. In this interactive AMA session, Valentina Scipione will answer your questions about careers in tech. Bring anything you have been wondering about, for example: * navigating the current job market * what hiring managers actually look for * career transitions within tech * job search strategy * how AI may reshape roles in data and engineering No slides. Just your questions and an open conversation. **Speaker:** Valentina Scipione **Bio:** Valentina Scipione is a Career and Leadership Coach, Engineering Manager, and hiring manager with a background in Astrophysics and more than a decade of experience in software engineering and quality. Based in Berlin and co-organiser of the PyData Berlin community, she brings together leadership experience and professional coaching to help tech professionals build more fulfilling careers with strategy, not autopilot. **Talk 2: Solving real life problems with basic Python** **Abstract:** 2 years ago I had the privilege and pleasure of meeting an amazing person who invited me to join the Python en Español community. This community is mainly aimed at people who have 0 to no knowledge about the language and they want to learn. The recurring problem for many of these practitioner is to find good real life examples to practice their skills. Did you know that you can solve 90% of business problems with only prints and inputs? well, maybe that was a lie but not far off from the truth. In this talk I want to guide you on how you can solve a real life case scenario of a business wanting to adjust the prices of their articles base on real time demand. Starting with a few variables an input and a print and slowly grow into a real time system consuming from different sources, to answer the hardest question there is. Was it worth it? or should we have stopped at reading from files 7 iterations ago? **Speaker:** Eric Rishmüller **Bio:** Eric works as a Lead Data Engineer at Thomann Musikhaus. He has been living in Berlin for the past five years and is originally from Argentina. Eric started sharing his passion for Python seven years ago and is quite active in Spanish-speaking Python communities. **Lightning talks** There will be slots for 2-3 Lightning Talks (3-5 Minutes for each).

**Google Analytics Alternatives** Is it finally time to make the switch away from Google Analytics? Two-and-a-half years ago Jason Packer asked this question at Columbus Web Analytics Wednesday. Since then: Google’s Universal Analytics has been sunset, we’ve changed our name to Columbus Data & Analytics Wednesday, and Jason has released two editions of his book “Google Analytics Alternatives”. Fresh off the release of the 2nd edition of his book, we thought it was time to re-open this conversation. While people love to complain about it, GA’s market share has remained relatively constant (at least in the United States). Why is that? You won’t find any complaints about GA4 in this talk, but rather an overview of what’s currently available in the market and how to frame your decision-making process. We’ll also be giving out some free copies of Jason’s book! So even if you’ve got a “GA4Lyfe” tattoo (no judgement), there’s free books to go with the free pizza and beer.
