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).

Happy New Year Colleagues, The next Columbus Futurists public forum will be **Thursday January 15 at 12:00 pm noon** (eastern) [https://osu.zoom.us/j/93451873651?pwd=RXIyZ2t5RjRqRG02UGQ1aEFVQ1NFZz09](https://osu.zoom.us/j/93451873651?pwd=RXIyZ2t5RjRqRG02UGQ1aEFVQ1NFZz09) Please come prepared to offer your **"What if?" questions for 2026**. (I will offer seven to begin our conversation.) I also would like to announce the publication of my latest book: *[Anticipatory Biographies: Personal Histories of the Future](https://link.springer.com/book/10.1007/978-3-032-08912-0)*, the tenth volume in the “Anticipation Science” series. Grounded in design fiction, futures research, anticipation science, and scenario writing, *Anticipatory Biographies* envisions how the world will be reshaped by artificial intelligence, technological automation, climate change, political disintegration, and the decline of higher education. This work of creative non-fiction bridges literary and scholarly forms, blending biography and design fiction with research-based insights to offer a narrative-based method for exploring futures. Ed Finn, Director of the Center for Science and the Imagination at Arizona State University says: “In this book **David Staley has invented a delightful new genre: the future biography.** He invites us to step into gritty, thrilling, and inspiring futures elbow-to-elbow with the characters living those stories. *Anticipatory Biographies* beautifully synthesizes Staley’s training as a historian, his expertise as a futurist, and his desire to ignite the imagination of his readers.” Hope you'll be able to read it, and hope to see you all on the 15th.

They are not taught merely for physical fitness and strength, but are a way of aligning the inner system to the celestial geometry, becoming in sync with the existence, thereby naturally achieving a state of health, joy and bliss.** **"Your physical health, your psychological wellbeing, and your spiritual possibility depend on how well aligned you are with existence. Essentially, hatha yoga is towards establishing this alignment." - Sadhguru** **Benefits of practicing Yogasanas regularly:** * **Stabilization of the body, mind, and energy system** * **Slows down the aging process** * **Relief of chronic health conditions** **Agility Level: Intermediate** **For ages 14+** **Open to everyone, no previous experience of yoga required**

This simple practice which you can do daily reorganizes your system on the elemental level.** **Benefits:** * **Keeps the system in harmony and balance** * **Prepares the system to handle powerful states of energy** * **Creates the basis to gain complete mastery over the human system** **For ages 14 and above, no prior knowledge of yoga is required.** **This program is conducted by a Hatha Yoga teacher trained by Sadhguru.**

2026 may be the last year many developers write code by hand. We need coding agents to solve complex problems in production codebases, but vibe coding alone won’t get us there. Vibe coding is all gas, no brakes. It burns up the context window until the agent slips on its own slop. You can go fast at first, but the more you stuff into the context window, the more tangled its outputs get. While the industry is rapidly increasing code generation speed, we still have to understand, review, merge, and maintain what gets shipped. This talk will outline how coding agents (Claude Code + Gas Town) work and a framework for orchestrating them to solve complicated problems in complex codebases. It’s about steering the model: doing the research to align intent, planning the approach up front, implementing in parallel steps, and breaking early. Human judgment still matters, but it should be spent on high-leverage decisions: what to build, what to forbid, and “what is quality?”, not cleaning up slop. Attendees will leave with a checklist to identify workflow and environment gaps that hold agents back, so you and your team can ship higher-quality software starting tomorrow.
