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!

Your next breakthrough might already be in the room. The Founders Room is a curated, high-value event by **FalAgency** where founders don't just listen they participate. Everyone brings something. Everyone leaves with something. **Here's what goes down:** * **Peer hot seats** \- put your business\, product\, or online presence in front of the room and get raw\, honest feedback from fellow founders who actually get it * **Live online presence audit** \- FalAgency breaks down how your business shows up digitally and what needs to change * **Growth insights from FalAgency** \- practical tips on building and promoting your business online * **Open networking** \- real conversations with founders who are building in the same world you are This isn't a conference. There's no stage and no audience. Everyone in the room has a voice, and that's what makes it valuable

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.

**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.
