Practice Buddhist meditation in the middle of Budapest! The meditation is suitable for beginners. Each regular meditation is guided and begins with a short introduction. (all together is about 30-40 minutes) Our regular Buddhist meditations have proven popular with people who want to integrate authentic Buddhist methods into their daily lives. For the modern lay person who is juggling work, relationships, and an active role in society, we teach a meditation that is easy to learn, and profound and powerful for experienced practitioners. The meditation originates from the Karma Kagyu tradition of Tibetan Buddhism. It has a cumulative effect on mind, leading to greater clarity and calmness. Fearlessness, joy, and active compassion are the result of regular practice of Buddhist meditation. * Do I need any special clothing? No special clothing needed. * Does the attendance cost anything? No, the meditation is free.

Join us for an evening dedicated to the evolving landscape of software engineering. As our tools become more powerful, our focus shifts from simply writing syntax to building architecture and stronger teams. We’ll explore two distinct sides of this evolution: the human side, where **peer and mob programming** foster trust and shared ownership, and the technical side, where **AI agents** allow us to "print code" and one-shot complex features. Whether you are looking to improve "team quality" or manage the "review bottleneck" of AI-driven development, this meetup offers practical insights for every engineer. This English-language event will be held at the **Formlabs Budapest office**, where we'll provide snacks and drinks to fuel conversations. Arrival is from 17:30, Announcements and agenda at 17:55, first presentations will start at 18:00. \-\-\- **Peer Programming to increase "Team Quality"** **with [Nico Riedmann](https://www.linkedin.com/in/nico-riedmann/)** Most engineers are familiar with pair programming. Your team may already encourage it to foster learning or as an alternative to ensuring code quality via pull-request reviews. This talk will show you the impact that collaboratively creating code has on "team quality" rather than just "code quality" - creating opportunities to build trust, increase shared ownership, and define and better understand a shared vision. And if you weren’t convinced before, we’ll end with a few practical tips on getting started with pair and mob-programming. **One-Shotting Features: The Reality of Agentic Workflows** **With [János Molnár](https://www.linkedin.com/in/j%C3%A1nos-moln%C3%A1r-9b582896/)** This talk explores our journey from using AI as a glorified auto-complete to one-shotting complex features. I’ll discuss our team’s evolution from using AI for basic code generation to adopting agentic workflows that shift our focus toward planning and architecture. We’ll explore the benefits of this high-level approach alongside the "review bottleneck" that occurs when AI velocity outpaces human auditing, and how we adapted our processes while releasing and building our Greenhouse project. \-\-\- Come learn and connect with other tech enthusiasts. See you there! You can also find the recordings of previous events on the [@DevBPMeetup YouTube channel](https://www.youtube.com/@DevBPMeetup).

“*Men being, as has been said, by nature, all free, equal and independent, no one can be put out of this estate, and subjected to the political power of another, without his own consent.*” ― John Locke, Second Treatise of Government *“There is no greater tyranny than that which is perpetrated under the shield of the law and in the name of justice. (Cambridge University Press (September 29, 1989)”* ― Charles-Louis de Secondat, baron de la Brède et de Montesquieu, The Spirit of the Laws *“The only freedom which deserves the name, is that of pursuing our own good in our own way, so long as we do not attempt to deprive others of theirs, or impede their efforts to obtain it.”* ― John Stuart Mill, On Liberty ## The Birth of Liberalism Liberalism emerges as a response to **absolute power**, religious conflict, and arbitrary authority. In this session, we explore the foundations of liberal democracies through three key thinkers, each addressing a different dimension of political power: **legitimacy, institutions, and liberty**. ## Core Thinkers ### **John Locke** * Natural rights: life, liberty, property * Government by consent * Political power as conditional * Right to resist illegitimate authority ### **Montesquieu** * Separation of powers * Liberty as protection from arbitrary rule * Checks and balances * Institutional restraint ### **John Stuart Mill** * Individual liberty * Harm principle * Freedom of speech * Tyranny of the majority **Introduction (15 minutes)** We start with a short introduction of the guests. **Questions to discuss: (1 hour and 45 minutes)** **Locke related:** * If rights are “natural,” who decides today when they conflict? * Does property still legitimize political power in a world of inherited wealth and financial abstraction? * Would Locke recognize modern taxation, surveillance, or emergency powers as legitimate? * Do we still believe in a real “right to resistance,” or only in theory? **Montesquieu related:** * Are separation of powers and checks still effective in today's estates? * What is the difference between institutions and bureaucracies? * Can power shift from institutions, to bureaucracies, to algorithms? * How can liberal institutions survive permanent states of exception (crises, wars, pandemics)? * Is slow decision-making a safeguard or a liability in the 21st century? * Where does power concentrate today despite formal separation? **John Stuart Mill related:** * Is social pressure more coercive today than the state itself? * How does “harm” according to Stuart Mill fit in an age of social media outrage? * Can free speech survive when offense is treated as violence? * Are we still willing to defend individuality or is moral conformity more important? * Would Mill see oppression in our democratic times? **General critical questions:** * Is modern liberalism still about limiting power, or mainly about managing society? * Can liberal democracies survive when large parts of the population no longer believe institutions are neutral? * Is today’s crisis of liberalism a moral failure, an economic one, or an institutional one? * Can liberal democracy exist outside Western historical conditions? * Can liberalism tolerate movements that openly oppose it? * Is liberalism too slow for the speed of modern politics and technology? **Critical questions from the right:** * Why do populist movements reject liberalism? * If liberalism weakens borders and traditions, can it still demand loyalty? * Has liberalism underestimated the political force of identity, culture, and belonging? * Can liberal democracy defend itself without becoming illiberal? * Is liberalism an external cultural imposition? **Critical questions from the left:** * When equality conflicts with liberty, which does liberalism choose? * Should equality come from public institutions or activist movements? * Is economic inequality undermining liberal legitimacy? * Can liberal values be separated from US influence and power? * Are anti-Western movements rejecting liberalism, or Western hypocrisy? **RSVP:** Please confirm your attendance here on Meetup to save your space and if you cannot assist, yield your space to another person in the waiting list.

**We are back. And by popular demand: We are finally doing this on a Friday!** For Event #4, we’re flipping the script. Forget the best practices. This time, we're focusing on **worst practices.** We’ll dissect real business failures through three lenses: legal, psychological, and marketing. Decisions that looked smart on paper, passed approval, and still detonated. We’ll revisit familiar disasters like **Theranos** and **Fyre Festival**, then go deeper into lesser-known, more uncomfortable cases and even scandals including global brand implosions and local examples like **Shrooly**. **This isn’t about laughing at failure.** It’s about understanding how smart teams convince themselves bad ideas are good ones, and learning how to spot the moment everything starts going wrong. **The Agenda & What You'll Learn** Three angles, one goal: Make sure you don't end up on this list next year. * **17:45:** Arrive, grab a drink (it's Friday!), and connect. * **18:00 – 18:15: How NOT to run your business (legal angle).** We look at the structural red flags that sink ships. From the valuation hallucinations of **WeWork** to the **Honey scam** and local hardware flops like **Shrooly**. We’ll cover how to mismanage cash, ignore the law, and implode your company from the inside out. * **18:15 – 18:30: How NOT to gain customers (marketing angle).** “There’s no such thing as bad publicity” is how this always starts. Then the backlash hits. We’ll break down campaigns that went viral for all the wrong reasons - from **Pepsi and Bumble** to **Bud Light and Apple** \- unpacking how rebrands\, stunts\, and culture\-driven ads cross the line from attention to alienation\, and how brands lose their audience because of some 'viral' ideas\. * **18:30 – 18:35:** **🎁** A super secret surprise * **18:35 – 18:50: How NOT to handle customers (psychological angle).** Users don’t leave when something breaks, instead they leave when something feels off. We’ll explore dark UX patterns, manipulative design, and behavioral shortcuts that quietly cross ethical lines from **friend.com** to platforms that optimized engagement until users turned hostile. This is how loyal users become your loudest critics. * **18:50 – 19:00:** A very special announcement * **19:00 – 20:00:** Genuine networking & conversations with quality food and drinks. * **20:00 onwards:** We are heading to a nearby bar. Since **nobody** has work tomorrow, we expect the conversation to go late. **Who Is This For?** This is for freelancers, digital nomads, and founders in Budapest who want to disaster-proof their work. Join a community of curious, open-minded people for an honest conversation. No corporate fluff, just genuine connections. If you want actionable takeaways on what *not* to do, this is for you. **Location** We'll be hosting at the fantastic **KLUSTER Coworking** space. **The Legal Bit** Our imaginary lawyers (who are currently panicking about this event topic) wanted us to mention that we'll be taking some photos. By attending, you consent to this. Thanks for reading, see you on **the 20th**! Bence & Marguerite & Nándi

In this session, we’ll explore how GitHub Spec-Kit enables teams to treat specifications as first-class artifacts—living documents that drive architecture, implementation, and verification. You’ll learn how Spec-Kit helps teams clearly express intent using structured, version-controlled specs that live alongside code. We’ll walk through a practical workflow that starts with defining system behavior and constraints, then progressively refines those specs into testable, automatable outcomes. Along the way, we’ll show how specs can reduce ambiguity, improve cross-functional collaboration, and make design decisions explicit before a single line of production code is written. This talk will cover: --What spec-driven development is (and what it isn’t) --How GitHub Spec-Kit fits into modern developer workflows --Using specs to align product, engineering, and AI-assisted development --Real-world examples of turning specs into implementations with confidence Whether you’re building greenfield systems, integrating AI into your stack, or trying to reduce costly rework, spec-driven development offers a scalable way to move faster without sacrificing clarity. Attendees will leave with concrete patterns and a clear mental model for adopting GitHub Spec-Kit in their own projects. **YouTube Link** TBA
