INFLUENCAIR - INFLUENCAIR - INFLUENCAIR Afhankelijk van de interesse vergaderen vandaag over: 1. De opgewaardeerde luchtkwaliteit display (fijnstof), nu met web-interface, met opvolging voor 32 locaties met elk 4 sensoren, met interface naar project Telraam (verkeerstellingen). Dit is eigen ontwikkeling van InfluencAir, en suggesties voor aanpassingen & verbeteringen zijn mogelijk. De source van de software is public domain (GNU GPL V3) en is gepubliceerd op Github (displayPM_32x4) 2. Er kunnen in deze sessie stand-alone displays van 53cm lang worden gebouwd. Het materiaal daarvoor wordt ter beschikking gesteld voor een bijdrage van 40 euro per display. 3. Een doorontwikkeling van deze display resulteerde recent in een kleine LCD display voor gebruik thuis, met dezelfde mogelijkheden. Deze LCD display zal ook kunnen worden gebouwd, en het materiaal daarvoor wordt ter beschikking gesteld voor een bijdrage van 20 euro per display. 4. Natuurlijk kan je ook een (gebouwde & geteste) fijnstofmeter met SDS011 en BME280 meenemen uit deze sessie. De prijs hiervoor is 45 euro. 5. Dit is ook een voorbereidende vergadering over de DNMS: de achtergrond geluidsmeter van het Sensor.Community project. Indien hier interesse voor is, kan dit in groep worden gestart. Gelieve mij vooraf een bericht te sturen indien de DNMS je ding is !!! 6. Idem voor een fijnstofmeter rond de SEN55, i.p.v. de SDS011. De voordelen van zo'n meter zijn dat naast de PM2,5/PM10 en Temperatuur/Vochtigheid/Luchtdruk ook nog de PM1/PM4 en de VOS/NOx waarden worden gemeten. Ook hier vooraf een bericht sturen indien dit je interesse opwekt. 7. Mensen die een Mosquitto server willen opzetten, gekoppeld aan een database, voor opslag en uitlezen van de metingen van de nieuwe meter beschreven in punt 6 zijn ook altijd welkom ! Ook hier vooraf een bericht, a.u.b. Breng je laptop mee.

Join our next meetup at Collibra on June 4th! We will have 3 talks about OpenTelemetry and will share some food and drinks while networking **Location:** Collibra, Rue Picard 11, 1000 Bruxelles **Agenda:** 17:45 : Doors open 18:00 - 18:30 : Drinks and pizza 18:30 - 19:10 : Talk #1 OpenTelemery on Kubernetes with EDOT: Getting started and what's ahead 19:10 - 19:50 : Talk #2 Taming Tenancy, Cost and Architecture at Collibra Through OpenTelemetry and Our Telemetry Backbone 19:50 - 20.30 : Talk #3 Closing the Observability Gap: OpenTelemetry Meets Elastic at Telenet 20:30 : Wrap up **Talks:** **#1 OpenTelemery on Kubernetes with EDOT: Getting started and what's ahead** **OpenTelemetry has become the default way to instrument applications and infrastructure, and Kubernetes is one of the places where it makes most sense to use it.** This talk is a tour of OpenTelemetry on Kubernetes, focusing on the Elastic Distribution of OpenTelemetry (EDOT). We will explore the OTel basics (general architecture, signals) and the recommended way to deploy OTel on Kubernetes using the OpenTelemetry Operator. A live demo with an Elastic backend will showcase the correlation of metrics and logs, demonstrating how everything ties in together. Finally, it will cover the current community effort to stabilize Kubernetes observability, including the promotion of Kubernetes attributes to release candidate status and the latest updates to the semantic conventions for Kubernetes metrics. This session is useful for beginners trying to get into OTel, and for those running OTel in their Kubernetes cluster and trying to get some insights on what is to come. *Speaker: João Marques Correia, Software Engineer at Elastic* **#2 Taming Tenancy, Cost and Architecture at Collibra Through OpenTelemetry and Our Telemetry Backbone** Operating a SaaS platform presents the same observability problems as any other enterprise, but due to the scale and tenancy, we introduce a huge multiplier on the observability signals, having an effect on cost and effectiveness. This session dives into the techniques Collibra used to tame these problems and how to maintain clarity when infrastructure spans virtual machines, modern Kubernetes clusters, and a complex mix of single- and multi-tenant architectures. Without the right context, telemetry data becomes a noisy, indistinguishable flood. We will dive into the architectural decision to leverage the C4 system model, ensuring every piece of telemetry carries the vital context of what it belongs to and where it sits in the hierarchy. Enabling us to gain insights into both signal attribution and allowing virtual chargebacks. The presentation details the implementation of a pipeline using custom-built OpenTelemetry collectors designed to handle the data and enrich it before sending it to the appropriate backends. This session will give you practical insights on the challenges SaaS platforms have, but the techniques that are used to tame them can be applied everywhere. *Speaker: Alex Van Boxel, Principal System Architect at Collibra* **#3 Closing the Observability Gap: OpenTelemetry Meets Elastic at Telenet** Modern systems generate more telemetry than ever, but without consistency, that data quickly becomes noise. At Telenet, we turned to OpenTelemetry to standardise how we collect and enrich observability data across our bare-metal Kubernetes clusters. This talk dives into how we integrate OpenTelemetry into our engineering workflows and couple it with Elastic for storage, analysis, and visualisation. We’ll walk through our architecture, instrumentation strategies, and how we ensure high-quality telemetry that engineers trust. Along the way, we’ll highlight real use cases, from debugging production incidents to improving service performance, and discuss what worked, what didn’t, and what we’d do differently today. If you're an Elastic user looking to adopt or scale OpenTelemetry, this session will help you bridge the gap between theory and practice. *Speaker: Reidar Veroft, Container Platform Engineer at Telenetgroup* **Bios** **Alex Van Boxel** is a Principal System Architect at **Collibra**. With an engineering background in Research and Development at Alcatel-Lucent, Progress Software, and Veepee he loves to focus on the fundamental building blocks of the software industry. That means reading, understanding, and contributing to specifications, as well as contributing to the Open Source projects that run through our infrastructure. He is code-owner of two components of the OpenTelemetry collector. **João Marques Correia** is a Software Engineer at **Elastic**. Having recently joined Elastic, he has been focusing on OpenTelemetry, with a bigger effort being put into Kubernetes metrics stabilization. Before joining Elastic, he worked as a Software Engineer at Cisco on a Data Center network controller. He is drawn to distributed systems, and in particular how to observe them and keep them working reliably. **Reidar Veroft** is a DevOps Engineer at **Telenet**, where he builds observable, reliable systems that power critical infrastructure across Belgium. From the 5G core to our voice core, he focuses on making sure the systems behind Telenetgroup are not only running, but fully understood through high-quality telemetry. **Thanks to Collibra for hosting this meetup!**

# Tired of dating apps or surface-level social events? This is different. Relational Labs is a guided connection experience for singles who want more honest, playful, emotionally intelligent interaction — without performance, pressure, or endless small talk. This is not speed dating. Not networking. Not “pitch yourself to strangers.” It’s a facilitated relational container rooted in psychology, emotional intelligence, attachment work, social dynamics, nervous system awareness, and real-world human connection — made practical enough that you can actually live it instead of reading another 50 books about it. ## What happens • A 2-hour guided online relational experience • Real-time connection exercises designed to create authentic interaction • A format that adapts in real time to whoever is present • Optional participant-led in-person continuation afterward • WhatsApp connection thread after the session ## This may be for you if: • You’re tired of shallow or repetitive social spaces • You want deeper connection without forced intimacy • You enjoy personal growth, psychology, communication, or relational work • You’re open to meeting people in a more intentional way ## Important This experience runs with whoever is present and takes its own shape each time. Sometimes expansive. Sometimes intimate. Both are the real thing. Booking happens through our website. 👉 Reserve your spot: [https://consciousconnectionsclub.com/join](https://consciousconnectionsclub.com/join) Optional in-person continuation: same day or within 48 hours depending on the city Most people come alone. People often leave surprised by how quickly strangers can feel human, warm, honest, and real. Sometimes awkwardness turns into ease. Sometimes curiosity turns into chemistry. Sometimes people simply remember what it feels like to actually connect again.
