Hi and welcome to our next Socrates Café philosophy meetup! Do you have a hunger for deeper understanding of yourself and the world? Do you value deep, honest and respectful dialogue? If yes, then this meetup will be very interesting for you. • WHAT IS A MEETUP ABOUT? We ask, answer and discuss questions and ideas to stimulate critical thinking and to widen our perspectives with new concepts and thoughts. The main purpose of these meetups is to enrich ourselves with the perspectives of others, not to convince others about our own perspectives. Our meetups are about our own philosophies of life and not necessarily what the great philosophers and academics have said or written. It is not a debating club or a platform for proselytizing. Instead, we place the emphasis on questioning, open mindedness and challenging our own assumptions while listening to and respecting the views shared by others. A Socrates Café meetup is considered a success when participants leave a discussion with many more questions than they had at the beginning. • WHAT TOPIC IS DISCUSSED AT THE MEETUP? Participants suggest topics at the beginning of each meeting. We then vote and choose that event's most popular topic for discussion. No academic training in philosophy necessary; just enthusiasm for exchanging ideas and points of view. Some examples of subjects chosen on previous meetups: * What ideals are worth dying for? * Why are we never satisfied? * Why is it that human beings know that the society is going wrong, leaders are well informed about it and things continue as is? * Is identity necessary? * How can it be that people in democratic societies are so obsessed with power? (Desire to be different, better, stronger than others) * What is friendship? • WHO PARTICIPATES AT THIS MEETUP? Anybody is more than welcome to join our meetups. Our events gather people from different backgrounds, different cultures, while no philosophical background is mandatory. Our usual participants are people that have a hunger for deeper understanding of themselves and the world. People that value deep, honest and respectful dialogue. The inspiration for Socrates Cafe originates with the book of the same name, written by the philosopher Christopher Phillips. (Socrates Cafe: A Fresh Taste of Philosophy, 2002). Phillips felt that the Socratic method of dialogue and discussion should be practiced not just in academic settings, but among everyday people interested in examining deep questions together. Hundreds of Socrates Cafe groups now exist around the world.

This is the second of a series of meetups dedicated to exploring the exciting world of **[OpenTelemetry](https://opentelemetry.io/)** within the cloud-native ecosystem. Whether you're just curious about observability or already a seasoned OpenTelemetry user, this series will offer valuable insights, practical knowledge, and opportunities to connect with fellow enthusiasts in the Barcelona cloud-native community. 📍**Location** 🆕 [Glovo](https://about.glovoapp.com/): c/Llull 108\, Barcelona \| [https://maps.app.goo.gl/371qvgfN5jj7atpcA](https://maps.app.goo.gl/371qvgfN5jj7atpcA) **👉 Here's a sneak peek of the agenda:** **18:30:** Check-in and welcome 👋 **18:45:** 🎙️ "**The 44% Price I Paid for Observability**" by **[Adrián Pastén](https://www.linkedin.com/in/adrian-pasten/)**, Software Engineer at [ApiumHub](https://www.linkedin.com/company/apium_hub/)**.** I added OpenTelemetry to find performance bottlenecks in my Kubernetes PHP application. Instead, OTEL became the bottleneck - consuming 44% of my system capacity and dropping throughput from 2,519 to 1,400 requests per second. Through live metrics and real production scenarios, I'll share what auto-instrumentation actually costs, when observability tools become performance killers, and practical strategies for getting the insights you need without destroying the speed you fought for. **19:15:** 🎙️ **"Efficient Tail Sampling at Glovo"** by **[Dani Medina](https://www.linkedin.com/in/dani-medina-3084b878/)**, Principal Software Engineer at [Glovo](https://about.glovoapp.com/) In this insightful talk, Dani delves into how Glovo has implemented a tailored tail sampling strategy to achieve two critical objectives: keeping operational costs under control and empowering developers to identify error traces effectively. **19:45 - 20:30:** Networking, Snacks, and Drinks 🍻🍕 We appreciate **[Glovo](https://about.glovoapp.com/)**'s generosity in hosting us at their Barcelona office and providing snacks & refreshments.

A war story about why "frontend-only" thinking fails on the server. **19:30 400 Tech Leads. Same problems. None of them technical.** Speaker: [Anemari Fiser](https://www.linkedin.com/in/ACoAAAsj0FIBwsd5kRTr2_wWLQKe-vFNZDCtNlE)\, O’Reilly Author \| Engineering Leader After training and coaching more than 400 tech leads across companies and industries, one pattern keeps repeating: when tech leads struggle, it’s rarely a technical gap. In this talk, Anemari Fiser shares the most common challenges tech leads bring into coaching sessions - overload, unclear expectations, ownership confusion - and assumed alignment, and why “getting better technically” almost never fixes them. Drawing from real coaching and training examples, the talk explores where tech leads get stuck, what they think the problem is, and the small but meaningful shifts that help them move forward. **19:45: Drinks and networking!** Do you want to talk at this meetup?

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

This is a free, in-person meeting on the subject of betrayals, losses and how to get over them so you can build lasting relationships. Burdened by a stressful relationship? Unhealthy relationships can trigger feelings of anger, despair or self-doubt. They can create dwindling spirals of fights and seeking to make-up, or trying to “pin the blame” on someone or something. If you don’t find the RIGHT reasons, or select the correct sources of the problem, the problem can just get worse and worse. Whether in love or personal ties, with friends or at work, our life really IS affected by the quality of our relationships. Good ones can promote pleasure and survival while less optimum ones can lead to annoyance, anger, self-doubt, stress, or even affect our health and ability to survive well. Whether you are suffering from a divorce, or a painful break-up, don’t know who to trust (or who to CHOOSE) as a partner, friend, boss or employee - the anxiety of relationship troubles can really make a mess of things. Maybe you’ve suffered a betrayal, or are dealing with hostility or criticalness or invalidation. Dwindling relationships can involve destructive behavior, where we hurt those we love, or start succumbing to self-destructive thoughts, attitudes or behaviors that spiral out of control and affect much more than our immediate relationship. Past losses in love or life can affect how we act or react to new people and situations and hold us back from even starting to create new, possibly great relationships! How can one get back onto a saner course of action? Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life: human relationships! Break free from self imposed limitations Here we will discuss: • How to “erase” the trauma of past hurts and betrayals so that one isn’t always repeating past mistakes. • Why and how do the negative emotions of others affect you? • Why is my partner withdrawing and what can I do about it? • Why do we sometimes feel compelled to hurt the ones we love? • Fights & arguments - what's really behind them? • What underlies “corrosive criticism” or the need to invalidate self or others? • How one can stably change one’s outlook on life so they can affect positive change? • Where do compulsive destructive behaviors come from and what can be done about them? • How to form closer bonds & keep growing the relationships with the people you care about? • How to enhance one’s own ability to survive and create positive healthy relationships whether in love, family & friendships or in work, business or one’s career? Relationships can be hard and life itself IS challenging. Why not arm yourself with the knowledge and breakthroughs that have been made about the mind, mental reactions & interpersonal relationships, so that one has better awareness and control over themselves and life in general. Learn where painful experiences are “stored” and how they can unknowingly affect us. You will also find out how one can “erase” those past painful experiences so that one is free to move forward without being tripped up by the past. Learn too, about what can lead some people to become “toxic” personalities and how to identify those traits in others so you won’t be tripped up trusting the wrong person. Our free Meet-ups occur in a safe environment where one can learn, without fear of judgment or criticism, and without the recommendation of harmful mental techniques or therapies, just how YOU can get yourself onto a happier & more successful path: in love & in life. We look forward to having you join us! This class is sponsored by the Dianetics & Scientology Life Improvement Center of Central Ohio.
