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. Thank you so much See you there!

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. **19:50: Drinks and networking!** Do you want to talk at this meetup?

**TICKETS HERE ->** [https://luma.com/e1ig4i7y](https://luma.com/e1ig4i7y?tk=bMSEwU) ** WILDFLOW VI — Music. Movement. Connection.** English version (Texto en español abajo)**** ​Imagine stepping into a space where you feel free, alive, and fully yourself. ​Where the music awakens something deep inside you. ​Where every breath, every beat, every glance around the room pulls you closer into connection — with yourself, with others, with life. ​✨ This is Wildflow. ​A 4-hour healing journey designed to leave you clearer, more connected, and full of life. **​ The Journey** **​1. Connect — Heart Awakening** ​As the sun sets, we gather in ceremony with cacao. Intentions are set, hearts are opened, and breathwork guides us into presence. A sense of unity begins to grow. **​2. Dance — Rhythmic Flow** ​The music invites movement: organic, tribal, and ethnic sounds that evolve into deep electronic rhythms. No choreography, no expectations — only freedom. The dancefloor is alive, constantly transforming as the night deepens. **​3. Heal — Energetic Release** ​What begins in grounded presence swells into intensity. The beats rise, the energy expands, the dancefloor becomes a temple of release and raw expression. You’re invited to let go, to discover new layers of yourself in the rhythm. **​4. Integrate — Reflective Landing** ​As the music softens, the collective energy settles. The dancefloor shifts again — from primal fire to gentle grounding. You leave balanced, uplifted, and renewed. **​ Why It’s Different** ​That moment of openness you usually chase with substances? ​At Wildflow, it happens naturally. ​Through breath, cacao, music, and trust, you find yourself dropping your guard, moving with abandon, and connecting in a way that feels real, alive, and lasting. ​No alcohol. No drugs. No muchrooms. Just presence, rhythm, and pure human energy. ​✨ Come alone or with friends — you’ll be welcomed into a safe space where connection happens naturally, and you won’t leave alone. **​ Your Invitation** ​Wildflow is not just a night out. ​It’s a dancefloor with intention — a space where your natural essence takes the lead. ​Join us, and remember how good it feels to be fully awake, fully alive, and fully connected. ​ Follow us on Instagram for exclusive sneak peeks! ✨ ​https://www.instagram.com/wildflow.ofc **​Meet the Hosts, DJs & Guest Artists** **​• Henk Schepens** ​Entrepreneur, Trauma-informed Space Holder & Visionary DJ ​**Instagram**: @henksky ​Henk’s journey of self-discovery and healing is deeply connected to the transformative power of music. Seeing its potential to unlock new levels of connection and growth, he is passionate about developing concepts that harness music’s healing energy. As a natural idea generator, Henk channels his experiences into meaningful projects that inspire and create space for exploration and self-awareness. **​• Jazmin Gattyan** ​Cacao Ceremony & Meditation Guide, Space Holder & Yoga Teacher ​**Instagram**: @jaz_happynest ​Jazmin works with ceremonial cacao as a sacred medicine for the heart—an ally that opens the doorway to presence, clarity, and authentic connection. Her ceremonies weave together cacao, guided meditation, and intentional ritual, creating a grounded space for reflection, release, and renewal. She invites participants to deepen their relationship with themselves, align with their inner wisdom, and connect with the collective energy of the group. Each ceremony is an invitation to return to balance, harmony, and heart-centered living. **​• DJ HNKS (Belgium)** ​Instagram: @hnks_music ​HNKS is a Belgian-born DJ with deep roots in Europe's electronic music heritage, HNKS has evolved into a globally recognized artist who brings his distinctive sound to dance floors worldwide. HNKS is known for blending innovative electronic music styles to drive the dance floor to new heights. ​• Guest Artists ​We’ll also invite special guest facilitators and artists , adding another layer of creativity and inspiration to the night. **​✨ Tiered Pricing & Community Support** ​Every WildFlow gathering is more than a dance floor — it’s a journey we co-create together. Each detail is carefully crafted: a beautiful venue, a high-end sound system with sub-woofer, ceremonial cacao, fresh fruits and spring water, and immersive décor that turns the space into a living, breathing and wild atmosphere. ​To make this possible — and keep it accessible — we use a tiered pricing system: ​€25 — Early Bird ​For the first visionaries who help bring the experience to life from the very start. ​€30 — 1st Release ​Join as the next wave of co-creators as the energy builds. ​€35 — 2nd Release ​Secure your place before we reach full flow. ​€40 — Last Chance (final week) ​For those who feel the call just before the event. ​A production with this level of intention, sound, and artistry would normally cost €75 or more, but we intentionally keep prices low to make the experience accessible and to invite you to be part of something new. ​When you join early, you’re not just saving on your ticket — you’re supporting the artists, the production, and the atmosphere that make WildFlow so unique. ​Your presence is more than a ticket — it’s an act of creation, helping shape a new culture of gathering rooted in connection, beauty, and the unifying power of music. **​Important Guidelines** **​1. Substance-Free Space ** ​• We maintain a strictly substance-free environment to promote clarity, genuine connection, and collective well-being. Please respect this policy by refraining from alcohol, recreational drugs, or other intoxicants. **​2. Respect & Inclusivity ** ​• Everyone is welcome. Treat all attendees with kindness and openness. Harassment, discrimination, or any form of harm will not be tolerated. **​3. Consent & Boundaries ✋✅** ​• Ask before engaging in any physical contact. If someone says “no,” please honor that without question. **​4. Dress Comfortably ** ​• Wear clothing that allows free movement and expression. Let your outfit reflect your energy—whether it’s sensual, wild, or uniquely original to you. Layers can help you transition from energetic dance to a calm cooldown. There is a no-shoe policy inside **​5. Minimize Phone Use ✨** ​• This is a space for genuine human interaction. If possible, keep photos and videos to a minimum. Stay present in the shared experience. **​6. Arrive Early ⏰** ​• The doors open at **6:30 PM**. ​• The journey start at 7:00 PM sharp! ​• The doors close at 7:30 PM, and we do not offer refunds for late arrivals. ​The opening ceremony sets the tone for the entire evening. Aim to arrive on time to fully participate in the grounding ritual. **​7. Stay Hydrated & Take Breaks ** ​• Dancing and movement can be intense. Feel free to take a break for water, rest, fresh air, or to enjoy some fresh 100% organic local farmer fruit whenever you need. ​• We kindly discourage stepping out to smoke and instead invite you to consider whether it’s worth interrupting your experience. **​8.

Conectar — Apertura del Corazón Al atardecer, nos reunimos en ceremonia con cacao. Se establecen intenciones, los corazones se abren y el breathwork nos guía hacia la presencia. Comienza a crecer una sensación profunda de unidad. ### 2\. Bailar — Rhythmic Flow La música invita al movimiento: sonidos orgánicos, tribales y étnicos que evolucionan hacia ritmos electrónicos profundos. Sin coreografías, sin expectativas — solo libertad. El **dancefloor** está vivo y se transforma constantemente a medida que la noche avanza. ### 3\. Sanar — Energetic Release Lo que comienza en una presencia enraizada se intensifica. Los beats suben, la energía se expande y el dancefloor se convierte en un templo de liberación y expresión auténtica. Estás invitado/a a soltar y descubrir nuevas capas de ti en el ritmo. ### 4\. Integrar — Reflective Landing Cuando la música se suaviza, la energía colectiva se asienta. El dancefloor vuelve a transformarse — del fuego primal al enraizamiento suave. Te vas equilibrado/a, elevado/a y renovado/a. *** ## Por qué es diferente ¿Ese momento de apertura que normalmente se persigue con sustancias? En **Wildflow**, sucede de forma natural. A través de la respiración, el cacao, la música y la confianza, bajas la guardia, te mueves con libertad y conectas de una manera real, viva y duradera. **Sin alcohol. Sin drogas. Sin mushrooms.** Solo presencia, ritmo y pura energía humana. ✨ Ven solo/a o con amigos — serás bienvenido/a a un espacio seguro donde la conexión ocurre de forma natural, y no te irás solo/a. *** ## Tu Invitación Wildflow no es solo una night out.

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.
