**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.

***TUE. 10/03: Beginners (7pm) + Special 8pm CLOSE EMBRACE course & 2 PRACTICAS*** Today we will start with the Beginner lesson at 7pm on the theme of the *Calesita*. And from 8pm: we are excited to continue our newest course, an intensive programme dedicated to building the close embrace, and understand the technique behind. Dates will be every Tuesday, until 07/04 and is open to Improver and Intermediate levels. You can join the whole course or individual workshops. **What is our new course about?** ***Mastering the Close Embrace*** is a course designed to make your tango feel more connected, comfortable, and effortless—especially in milongas where space is limited. We’ll refine the embrace itself (posture, tone, breathing, elasticity, and how to “hold” without gripping), then build the technique that makes close embrace work: clean weight changes, grounded walking, shared axis awareness, dissociation without strain, and pivots that stay compact. You will learn how to communicate clearly through the chest and intention, improve synchronisation and timing, and create fluidity through simple, high-quality movement. Expect practical drills, guided partner work, and floorcraft training—how to find space, manage traffic, and move gracefully around the line of dance—so you finish with a calmer lead/follow, better musical response, and a close embrace that feels safe, elegant, and genuinely enjoyable for both partners. \-\-\- DETAILED PROGRAMME As usual your Beginners class is at 7pm, and from 8pm (in the small hall) we will run ***MILONGUITA***, the Beginners’ milonga. And in the main hall, your 8pm class will be until 9.30pm, and we will follow with our practica, ***LA YUMBA!***, for students and whomever wants to join. Join us for lovely embraces and a friendly and welcoming practica. * MORE: **[https://tanguito.co.uk/tuesday/](https://tanguito.co.uk/tuesday/)**

The aim is to learn a little more than before you started. This event is for those new to coding through to more experienced developers. We organise into small groups (2-4) people and write code to solve challenges great and small, chosen by those at the event. We aim to ensure someone in your group has some Clojure experience, so you shouldn't feel lost (well no more than all developers do when Stack Overflow is broken).

Clojure is a JVM language that has syntactically similarities to Lisp, full integration with Java and its libraries and focuses on providing a solution to the issue of single machine concurrency. Its small core makes it surprisingly easy for Java developers to pick up and it provides a powerful set of concurrency strategies and data structures designed to make immutable data easy to work with. If you went to Rich Hickey’s LJC talk about creating Clojure you’ll already know this, if not it’s well worth watching the Rich Hickey “Clojure for Java Programmers” video or Stuart Halloway “Radical Simplicity” video .

For our March meetup, we're back at the fabulous Accurx offices. We have two excellent talks lined up, the agenda will be: * 6:30pm - arrive, drinks, networking * 7:00pm - Welcome & Housekeeping * 7:15pm - **Talk 1: "Devops 2014 Revisited - a Dozen Years of Noise and Confusion"** It is 11th February 2014, a nervous Andy Burgin takes the stage at Agile Yorkshire and begins to share the current thinking from the burgeoning DevOps movement. Fast forward 12 years: DevOps is different — or is it? During a recent clear-out at chez Burgin, an old, forgotten laptop was discovered discarded between a box of floppy disks and a collection of old Computer Shopper magazines. While the laptop was no longer functional, a painstaking data recovery process rescued the files on its hard drive via a collection of old adaptors and half-working wires. Among the files saved from the Wakefield Council recycling centre was a copy of the very PowerPoint deck presented at that meetup 12 years earlier. But what was in this digital "time capsule"? What happened to DevOps? What did it become? Is it now a tool, a job title, or did something "bad" happen to it? Are the thoughts shared over a decade ago still relevant today? Join Andy as he looks at how we travelled from DevOps to Cloud, SRE, Platform Engineering, Team Topologies, Developer Experience, and VibeOps - Most importantly, we'll explore what the future of DevOps can learn from its past. **Speaker:** Andy Burgin, Principal Platform Engineer @ Flutter UK and Ireland *Andy is a Principal Platform Engineer at Flutter UK and Ireland. He considers himself a Kubernetes, AI and DevRel fettler, spending far too much of his spare time running software in containers that really shouldn't be. He is a small part of the organising team for DevOpsDays London and ran the DevOps meetup in Leeds for almost a decade hosting over 50 events. He’s attended and has spoken at a bunch of DevOps conferences and in his own words is an "all-round DevOps nuisance".* * 7.45pm - food, more drinks & networking * 8.00pm - **Talk** **2: "Navigating From Tension to Flow: A Human-Centred Guide to Overcoming Misalignment"** Behind every stalled project, missed milestone, or unclear decision is a story of tension between what people want, what’s needed, and what’s possible. But tension isn’t failure. It’s feedback. This talk explores how to recognize and respond to tension using Team Topologies principles, flow first thinking, and a healthy dose of human insight. We’ll show how organizational patterns, team boundaries, and interaction modes can either amplify or ease misalignment — and how trust, empathy, and bold conversation are just as important as structure, if not more so. Packed with real-world examples, this session blends organizational design with emotional intelligence to help you design for flow — and for people. **Speakers:** Faye Benfield, Product Leader, Independent & Rich Allen, Fast Flow Facilitator @ Conjurer *Faye Benfield is a Product Leader with over 15 years experience in product management, agile delivery and digital transformation. Specialising in helping organisations adopt product practices, Faye has a proven track record of embedding product teams, evolving ways of working, and aligning stakeholders to achieve strategic goals. Faye has held leadership roles, including Head of Product and Delivery at Parkinson’s UK and Head of Product at Comic Relief, where she spearheaded digital transformation initiatives and cultivated effective, people-centred teams. As a consultant at Armakuni, she combined hands-on coaching with practical tools and techniques to help clients navigate the complexities of product delivery, with a focus on balancing human dynamics and practical constraints.* *Rich Allen is a sociotechnical architect, consultant and creator of User Needs Mapping, a practical technique for aligning teams around what matters. With over 20 years’ experience across software engineering, technical leadership, and organisational design, Rich helps organisations reduce friction, clarify boundaries, and improve flow by working outside-in from real user needs. He was a foundational contributor to the development and teaching of Team Topologies, helping shape the core materials now used in Team Topologies training and consulting worldwide. Rich is the author of User Needs Mapping: Aligning Teams Around What Matters.* * 8.30pm onwards - drinks and networking. So, please come and join us, we look forward to seeing you there. The LOPUG team. * Food and drinks provided * Good time will be had by all

**Please note~ RSVP will open one week before each event. This is to avoid no shows. If you are unable to attend please mark yourself as ‘not going’ so someone else can attend in your place. Thank you. ** It's a board games club with a twist! We have a variety of games to play as well as the usual titles and favourites like Secret Hitler, Exploding Kittens and Uno so come on down if this sounds like fun to you! The games will be easy to understand as well, so don't worry about your level of board game experience! And remember to BYOBG (bring your own board games) if you have any that you would like to share :) We will meet inside TCR Bar for around 1pm. We will be seated in the boths at the back of the bar. Food and drinks are available from the bar. It would really help the venue if you could make a small purchase from the bar. Thank you.

**We are holding an Agile Standup dinner at the Mercato Metropolitano food court.** https://mercatometropolitano.com/locations/elephant-and-castle/ The focus of the evening is to enjoy amazing food while networking, learning and discussing using agility to create better software, products, teams and organisations. **The evening will take the form of a round table discussion** \- Bring a great question or describe a problem which you'd like to share\, we will then discuss it at the table\. **Who might come along?** Whether you're a seasoned agilest or completely new to it, you are most welcome. **The Dinner** \- Be prepared to pay for your own food and drinks\, what you choose is up to you\. **On the night:** The event starts at 6:00pm, hopefully we'll not be that hard to find. When you arrive, join us and order a drink. We'll aim to eat at around 7pm. Afterwards there will be an opportunity to meet, mingle, discuss and maybe even find mentors or future work colleagues. If you have any questions, just drop us a line. We will finish at around 9:00pm, but you can leave earlier, if you need to. *Photographs may be taken throughout the evening, please let the organisers know if you would prefer not to be featured in them.* Looking forwards to seeing you there.

¡Hola, afición! Join us for a football-themed language exchange in London, taking place at Sway bar, Holborn on Wednesday 11th March We’ll kick things off at 7:30 PM, with pre-game networking, leading up to City vs Madrid kicking off at 8:00 PM.

We are back! This is going to be a monthly IN PERSON meet up in London. A very big thank you goes to Accurx who is hosting us in their amazing Shoreditch offices. This will include access to facilities including coffee! 😻☕️ **Want to know more? 👇** As with all CoffeeOps, this is an interactive, chatty, build your own adventure type of meet-up. Instead of booking in experts to *learn* *from*, we gather a group of practitioners to ***learn*** ***with***. We have been running for over 4 years now and often get feedback that this is the most useful meetup people join! The event is approximately 90 minutes and always starts by brainstorming topics to discuss. The group then votes on the most relevant/interesting to them and we then cycle through the topics trying to discuss each deeply, but in a time bound slot. To get an idea of topics, you can check out our remote board [here](https://easyretro.io/publicboard/h404NF84Uje4tCcxpJdHr4Ycs9B3/a4a35d2b-181b-409b-832e-a729be1af79c). The general gist is anything is fair game, though we tend to revolve around software delivery and definitely lean towards the more Ops-y or DevOps-y side of things.

Join other experienced and aspiring agile coaches and professionals to: * develop and practice your coaching skills in a peer-to-peer environment * share current successes and challenges in your work environment and get support from each other * learn from each other, build better relationships and experiment with new ideas

The Humanist Monthly Program is our longest running event and still a community favorite. In the old days it used to be called "Going to HCCO" and we still like to think of it as our flagship event. Food and drinks will be provided at the event. Feel free to show up a little bit early to hang out and talk. Our March speakers are Molly Gaines and Zack Parrish, co-organizers of the Secular Education Association: They will share their story of how a small group of Ohio parents grew into a national organization tracking released-time religious instruction and other church–state issues in public schools. The presentation will cover SEA’s early wins and hard lessons, what we’re seeing nationally right now, and how local advocates can play a meaningful role in protecting public education. Attendees will leave with a clearer understanding of the landscape — and practical ways to get involved. Going forward our meetings will be hybrid.

## Hey Columbus WIP peeps! ## Are you ready for an event that actually gives you what you asked for?? **\-\-\-\-\-\-** **A Small-group coaching conversations for women in product navigating growth, leadership, and career decisions.** **March 10 \| 5:30–8:00 PM** **Rev1 -- NEW SPACE** **330 Rush Alley #100** **Parking Options:** • **Rev1 at The Peninsula** • **Starling St. Garage South** – 377 W. Capital St. • **LAZ Parking (COSI)** – 50 Belle St. • **LAZ Parking Limited** – 375 W. State St. • **Veterans Memorial Lot** – 300 W. Broad St. • **Metered Street Parking** **What moves are you making?** A promotion you’re working toward. A role change you’re considering. A bigger leadership opportunity. A conversation that needs to happen. A decision that’s been sitting in the back of your mind. For our Q1 Women in Product Columbus event, we’re creating space to actually work through those moments. **Making Moves** is an evening of focused, facilitated coaching conversations with experienced mentors from our local product community. This isn’t a panel. It’s not passive networking. It’s small-group dialogue designed to be thoughtful, practical, and worth your time. Here’s how it will work: • You’ll choose a topic that reflects what you’re navigating right now • You’ll join a small coaching circle (5–7 participants) • Each circle is led by a mentor who has lived experience in that area • We’ll run two rounds so you can go deeper or explore a second conversation ### Coaching Topics: • Communicating the Value of Your Work (or Team) • Career Transitions & What’s Next • Growing Into Leadership • Staying Relevant as Technology (and AI) Changes • Getting Alignment and Decisions from Leadership Our goal is simple: you leave with clearer thinking, practical perspective, and at least one next step you feel confident about. Space in each circle will be limited to keep conversations meaningful. If this sounds like the kind of room you’ve been wanting to be in, we’d love to see you on March 10. RSVP here! [https://community.womenpm.org/c/all-local-events/making-moves-a-columbus-wip-event](https://community.womenpm.org/c/all-local-events/making-moves-a-columbus-wip-event "https://community.womenpm.org/c/all-local-events/making-moves-a-columbus-wip-event") *And if you haven't joined the WIP group - do that too, would ya?!?!* — Your Columbus Chapter Leads - Amber, Leah and Liz!

One of the most valuable parts of this community is the opportunity to think out loud with other product professionals. This session is built for exactly that.

Join fellow product professionals for a focused, interactive conversation designed to help you recalibrate for the next quarter. You’ll have the opportunity to share where you are, hear how others are thinking through similar challenges, and gain fresh perspective you can bring back to your team and organization. We’ll gather at 8:00AM, with discussion starting promptly at 8:15AM. 📍 First Watch - 7227 N High St Located in: The Shops at Worthington Ample parking is available. Food and beverages will be available for purchase. Start your morning with clarity and connection — we hope to see you there! ☀️
