**When nothing happens: Bayesian approaches to testing for "no effect"** We are delighted to have Mircea Zloteanu for the first Bayesian Mixer of 2026, please register here: https://www.tickettailor.com/events/bayesianmixer/2066946 **Abstract:** Non-significant p-values do not constitute evidence for the absence of an effect, yet researchers often wish to make claims about “no difference.” Often this will lead to publications that make incorrect statements (i.e., claim no difference when the data is just uncertain) or even deter researchers from pursuing specific hypotheses or publish their work. This talk presents Bayesian alternatives for evaluating null results. First, I demonstrate Bayes Equivalence Tests for interval (composite) hypotheses. Second, I illustrate the default Bayesian t-test method relying on model comparison (using the JZS Bayes factor), showing how routine analyses can quantify evidence for or against a point null. Third, I introduce posterior-based equivalence testing using the Region of Practical Equivalence (ROPE) via bayestestR. Together, these approaches provide principled tools for publishing credible null findings. **Bio:** Mircea Zloteanu is a Lecturer in Psychology and Criminology at King’s College London, where his focus is on Research Methods and Statistics. He received his PhD in Experimental Psychology from University College London and has previously held posts at UCL, Teesside University, and Kingston University. His recent work focuses on meta-research, statistical methodology, and improving research practice, with particular emphasis on Bayesian methods, equivalence testing, and transparent reporting. Mircea is actively involved in the open science movement as UK Reproducibility Network Local Co-Lead and a member of ReproducibiliTea, promoting reproducible, rigorous, and cumulative psychological science.

The London Mountaineering Club's weekly club night at Westway takes place every Tuesday. There will be many more of us at the wall than listed on this event. To find us, look for people wearing an LMC T-shirt. This is a friendly meetup for competent climbers (at all levels of aspiration) to find people to climb with. If you have not climbed at Westway before, you will need to pass Westway's safety test before you can climb unsupervised. If you are unsure whether the centre will allow you to climb unsupervised please message the event organiser on Meetup in advance. We may be able to arrange supervision for you to climb without passing the test but this depends on club members being available to supervise and places will be limited. The London Mountaineering Club does not charge for this event but you will need to pay the entry fee to Westway and for any gear hired. Details of the Westway climbing wall are available on the [Everyone Active website](https://www.everyoneactive.com/centre/westway-sports-fitness-centre/climbing/) including [prices](https://www.everyoneactive.com/centre/westway-sports-fitness-centre/?activitySearch=casual%20climb).

Join us on March 10th from **6:00pm** for a Data Streaming meetup hosted by **[Fresha](https://www.fresha.com/)**! 📍**Venue:** **Fresha** The Tower, 207 Old Street London, EC1V 9NR 7th Floor **PLEASE bring your PHOTO ID and REGISTER with your First and Last Name, Email. Thanks!** **DOORS CLOSE AT 7PM FOR SECURITY.** 🗓 **Agenda:** * 6:00pm – 6:30pm: Food/Drinks and Networking * 6:30pm - 7:00pm: Jesús Gómez-Escalonilla Guijarro, Data Engineer @ Fresha * 7:00pm - 7:30pm: Pranam Codur, Senior Solutions Engineer @ Confluent * 7:30pm - 8:00pm: Sreeram Machavaram C, Principal Architect @ Cognizant * 8:00pm - 9:00pm: Q&A Networking 💡**Speaker One:** Jesús Gómez-Escalonilla Guijarro, Data Engineer @ Fresha **Title of Talk:** Optimizing StarRocks Query Performance: Lost in JSON, Found by Northstar **Abstract:** StarRocks is fast, but understanding slow queries at scale is hard when plans are massive JSON. We built Northstar at Fresha to turn plans and execution metrics into a visual view you can reason about quickly. Through production case studies that reflect our real workloads, we'll show the bottlenecks Northstar exposed (scans, joins, skew, modelling) and how it made tuning faster and more systematic. **Bio:** Jesús Gómez-Escalonilla Guijarro is a Data Engineer at Fresha, where he focuses on building scalable and performant analytical data systems. He has been part of Fresha’s data team for several years, first as an Analytics Engineer and now in his current role, helping shape how data is modelled, analysed, and optimised across the organisation. Passionate about making complex systems understandable and efficient, Jesús enjoys tackling performance bottlenecks and sharing learnings with the wider data engineering community. 💡**Speaker Two:** Pranam Codur, Senior Solutions Engineer @ Confluent **Title of Talk:** From Data Mess to Data Streaming Platform **Abstract:** Most organizations want realtime data but are held back by brittle integrations, batch ETL, and siloed warehouses. In this session, we’ll walk through the Confluent Data Streaming Platform (DSP), which is built on Apache Kafka® and Apache Flink®, and a reference architecture you can use to ship governed, reusable real-time data products that power applications, analytics, and AI workloads. Attendees will leave with practical patterns to modernize existing Kafka and batch pipelines while maintaining security, lineage, and compliance. 💡**Speaker Three:** Sreeram Machavaram C, Principal Architect @ Cognizant **Title of Talk:** From "Data Rich and Information Poor" utility To "Event-driven, Real-time intelligent" operations **Abstract:** Utilities are massive and complex. Whether it’s water, gas, or rail, they operate treatment works, pumping stations, compressor sites, signalling systems, and vast networks that span cities and regions. Keeping these services running safely and continuously means collecting and interpreting data from highly distributed sites and their connected networks in real time. This machine data — from PLCs, sensors, third-party devices, and operational systems — reflects the physical world: pumps starting, valves opening, pressure fluctuating, trains moving, gas flows changing. But raw telemetry is noisy, inconsistent, and deeply technical. SCADA and other OT systems are often siloed and reactive. Engineering signals are hard for IT to interpret, leaving organisations unable to combine OT data with IT-based analytics and intelligence in real time. The result: fragmented visibility, alarm fatigue, and reactive decision-making. A Unified Namespace (UNS) and event-driven stream processing provides a solution. Using MQTT to publish operational events, Kafka as the enterprise backbone, and Flink for scalable stream processing, raw telemetry is filtered, contextualized, and transformed into meaningful, business-ready events. The outcome is IT-OT convergence in action — turning reactive, siloed systems into event-driven, real-time intelligent operations Intended to give a high-level approach and architecture around IO-OT convergence using UNS, Event Driven and Stream processing in modern intelligent utilities. **Bio:** Sreeram Machavaram C is hands-on practitioner specialising in utility solutions across IT-OT convergence, real-time data architectures, and stream processing. He works in a team that designs and builds event-driven systems that bridge operational technology (OT) and enterprise IT, enabling utilities to transform raw telemetry into actionable intelligence. \*\*\* If you are interested in hosting/speaking at a meetup, please email community@confluent.io

Wouldn’t it be nice to find a way to overcome your feelings of anger so that you not only control them, but you no longer have the urge to lose your temper in the first place? And how about being able to shake off resentments, persistent annoyance, or even feelings of vengeance? We’d like to invite you to an event on how to overcome anger and resentment. We will show you why people have trouble controlling their temper and where resentment comes from. Flaring anger can ruin a meeting, a relationship, an opportunity, or just about any aspect of life. Worst of all, outbursts towards our family can create hurt that lingers throughout a lifetime. You want to have a civil conversation, and you’ve vowed that you wouldn’t lose your temper, but a few minutes later, the anger flares up. Maybe you’ve realized that being angry doesn’t get you what you want so you internalize it. Or maybe you avoid the knockdown, drag-out fights, but stewing in resentment is exhausting and takes an emotional toll. In this event we show you how to get to the root of your anger so that it stops being an issue to you. You’ll also learn why people harbor resentments and how to move on. Don't continue to struggle, make a difference in your life, and join us for this local event. Be sure to click on the red "Attend" button below to come to the event. We look forward to seeing you there. This Meetup is sponsored by your local Dianetics and Scientology Life Improvement Center.

**Google Analytics Alternatives** Is it finally time to make the switch away from Google Analytics? Two-and-a-half years ago Jason Packer asked this question at Columbus Web Analytics Wednesday. Since then: Google’s Universal Analytics has been sunset, we’ve changed our name to Columbus Data & Analytics Wednesday, and Jason has released two editions of his book “Google Analytics Alternatives”. Fresh off the release of the 2nd edition of his book, we thought it was time to re-open this conversation. While people love to complain about it, GA’s market share has remained relatively constant (at least in the United States). Why is that? You won’t find any complaints about GA4 in this talk, but rather an overview of what’s currently available in the market and how to frame your decision-making process. We’ll also be giving out some free copies of Jason’s book! So even if you’ve got a “GA4Lyfe” tattoo (no judgement), there’s free books to go with the free pizza and beer.
