Lean Startup

Join us in Tallinn on **July 2nd at 18:00** for our next meetup, hosted by [Entigo](https://www.entigo.com/)! This time, we will explore the ins and outs of building and managing your own PostgreSQL setup, guided by two amazing speakers. We are going to explore building/managing own PostgreSQL setup with help of two amazing speakers. [Henrietta (Hettie) Dombrovskaya](https://www.linkedin.com/in/henrietta-dombrovskaya-367b26/) **Making Access Control Management Easy: Introducing pg_acm** PostgreSQL does not have any prescribed guidelines for the use of schemas, also called namespaces. A namespace is just one of many attributes of an object, whether an object is a table, a view, a function, or any other object type available in PostgreSQL. One of the common reasons for using schemas is to simplify access control management. The idea is straightforward: all objects within one schema should have identical access privileges. As simple as it sounds, the practical implementation of this approach can quickly turn into an operational nightmare unless all participants agree to follow a set of rules that are difficult to enforce. That is, unless you use pg_acm: an access control management tool for PostgreSQL, which we are going to introduce in this talk. The only thing you need to do is to define an access management policy for your database. Once it is defined, a CREATE SCHEMA command will invoke the creation of a set of event triggers and roles. All of them, working together, will ensure your access policy enforcement. No more accidental grants to PUBLIC. No more mysterious “permission denied” errors. You are in control. [Martin Vool](https://www.linkedin.com/in/martin-vool-86436018b/) **How Hard Can a Simple Kubernetes PostgreSQL Self-Service Be?** "How hard can it be?" We thought building a simple self-service was easy: let developers order a PostgreSQL instance, its databases, and users straight from the Kubernetes API, without caring which cloud runs underneath. Using managed services like AWS RDS behind a clean Crossplane-based interface, the first prototype came together fast and then day 2 arrived. This talk is a field report on everything between "it works!" and production: Kubernetes finalizers and RDS deletion protection that trap objects in limbo, backups you can only restore into a brand-new instance, and the day a user deleted an entire namespace and took our teardown logic with it. Along the way we leaned on Kyverno policies as duct tape and an upstream PR still stuck in review. If you build self-service infrastructure on Kubernetes or just enjoy other people's operational scar tissue you'll leave with concrete patterns and a healthy respect for the word "simple." **Additionally:** * **A Word from Our Host:** A brief welcome from the team hosting us. * **Lightning Talks:** Have a topic or idea? Let the organizers know if you'd like to present! * **Hallway Track:** Enjoy a cozy and practical space for networking and conversations between presentations. **Organizational Details:** * **Check-in:** There will be a secondary RSVP at the doors (Entigo will act as the data controller). * **Parking:** Free parking is available behind the building. * **Recording:** We are planning to record the event on video and will share more details once they are finalized. Looking forward to seeing you there!

You can sleep in on the Sesquicentennial (observed), we’re shifting to the following Friday. But join the local UX community for a chat and some biscuits to catch up. If you were in CA for Figma Config, tell us all the lines and you can tell me how I can animate an SVG without coding it by hand, and why I’d even want to. Thanks to the team at Nationwide of supporting the group.

Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on. That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable. In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork. This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it. We’ll cover: * Why “it looks good” is not enough * How to improve prompts by changing the input, context, and constraints * How to compare LLM outputs more systematically * Basic evaluation techniques for accuracy, consistency, and usefulness * How embeddings, cosine similarity, and scoring can help evaluate results * Where automated evaluation works — and where humans still need to stay in the loop By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.

We are recruiting new group leaders for virtual men's groups! Our primary groups are outdoor movement groups, but we are launching virtual groups for the state of Ohio and beyond and the groups will move outside in the spring, creating room for men's groups, women's groups and coed groups all over the country. Read below to learn about our groups and click the links at the bottom to apply. ### **What is an Outdoor Empowerment Group?** Our Outdoor Movement & Community Empowerment Groups are simple, guided experiences designed to help people reconnect with nature, themselves, and others. We combine some form of movement (hike, walk, run, bike, yoga, workout) and meaningful conversation within a simple community circle to create a space where individuals can support each other while prioritizing mental and physical well-being. Whether you’re seeking stress relief, personal growth, or community, our groups offer everyone a unique and welcoming environment. ## **Why Join?** * **Improve Mental & Physical Well-Being** – Movement, nature, and supportive conversations reduce stress and promote balance. * **Feel Less Alone** – Build genuine connections with like-minded people in a safe, welcoming space. * **Gain Clarity & Perspective** – Step outside daily routines and into a space designed for personal growth and reflection. ## **The Ideal Group Leader** The ideal group leader * Has a born-in passion for mental health, movement, connecting with nature and building community. * Has 5 extra hours per week to dedicate to a meaningful cause for at least one year. Yes, you can leave any organization at any time and we can also ask you to leave, but we are building with legacy in mind and we need people who can commit and be ALL IN on this mission to build with us. * Is independently financially stable with the ability to volunteer with no expectation of pay. This is a deeply beautiful journey of service that all participants commit to at Speak Your Mind. * An ability to manage groups with high emotional intelligence and desire for human connection. * An ability to self-motivate and market/promote their group on Facebook and other social platforms. * Nature informed therapy or clinical therapists/psychologists a plus. ## **Our Impact**  Since launching, we have helped thousands find support, connection, and healing through our Outdoor Movement Groups. 100% of participants surveyed have reported: * A noticeable improvement in mental clarity and emotional well-being. * An increase in social connection and a sense of belonging. * Said they would return again. We believe mental health should be accessible, community-driven, and rooted in nature. Join us and take the first step toward a more connected, grounded, and supported version of yourself. ### **Why Our Groups are Donation-Based** Our Outdoor Movement Groups are made possible through a donation-based model. This approach allows us to keep our events accessible to everyone, regardless of financial circumstances, while also ensuring that we can continue expanding our reach. It’s a great way to pay it forward and support the growth of this beautiful mission! Every contribution helps us: * **Cover Essential Costs** – Donations allow us to pay essential legal, marketing, insurance, and admin costs as well as nourish the important people who run the organization. * **Grow Our Mission** – With your support, we can bring these healing experiences to thousands more people in the future and execute our long term plan to expand across the USA, affecting up to 500,000 people per year.

**Practical Curiosity: Learning from Everyday Data** How do we actually get better at utilizing our day-to-day data? Fancy dashboards and complex models might look nice and draw attention, but that’s not where most of us spend our time. In fact those shiny outputs frequently sit unused, while the real insights are drawn from the analyst’s daily practice. Sometimes it’s as simple and as powerful as noticing that a segment is shrinking, a channel is underused, or certain links keep getting all the clicks. There’s many different places that the spark of insight can come from, but you have to keep your head in the data and know where to look. In this session, we’ll explore real-world examples of how segmentation, testing, and click behavior can uncover practical digital marketing opportunities. You’ll leave with inspiration for your own use cases, along with a few simple ways to ask better questions, spot meaningful patterns, and make smarter decisions without overcomplicating it. **About Our Speaker:** [Elaine Armbruster](https://www.linkedin.com/in/elainearmbruster/) is a Director of Digital Experience at the [American Diabetes Association](https://diabetes.org/), where she focuses on using data and insights to create smarter, more effective digital experiences. A lifelong Columbus resident, she has built her career in email marketing and the broader digital user journey, and is finding she most enjoys working in the messy middle where systems, data, and big ideas don’t quite line up yet.
