PyData Helsinki will meet at **UpCloud**'s office! Schedule: 16:30 Doors open 17:00 Welcome words from **UpCloud** 17:10 **Seija Sirkiä**: *NPS - Not Proper (data) Science?* 17:40 **Touko Väänänen**: *Choosing projects under uncertain preferences for impacts* 18:10 Break — food, drinks, networking 18:45 **PyData Helsinki** **quiz** 19:00 **Alexander Kevin Gilbert**: *Learning Data Engineering (not) from scratch* 19:30 End of programme 20:00 Continue at a nearby bar Talks: * **[Seija Sirkiä](https://www.linkedin.com/in/seija/)**: *NPS - Not Proper (data) Science?* Everybody agrees that Net Promoter Score is not quite as magical as it's made to sound like, but there's still plenty you can do with that data. In this talk I will show what I learned about that while working at HappySignals, including a model that cleans the scores of subgroup effects, such as culture/country. * **[Touko Väänänen](https://www.linkedin.com/in/touko-v%C3%A4%C3%A4n%C3%A4nen-89150114a)**: *Choosing projects under uncertain preferences for impacts* Many choice situations involve choosing a subset of possible projects with several types of impacts. Choosing between the projects introduces trade-offs between the impacts that decision makers disagree about. I present a framework which helps in assessing robust projects that would be chosen with many preferences over the impacts. * **[Alexander Kevin Gilbert](https://www.linkedin.com/in/alexander-kevin-gilbert-2449b5237/)**: *Learning Data Engineering (not) from scratch* A PhD in physics and big data analysis experience at CERN might seem irrelevant when applying for a data engineering job, as the tools are completely different. But the two worlds are more connected than they appear. Join me as I explore those connections and share what I've learned along the way.

Learning Finnish in Finland can be difficult because Finns tend to switch to English. That is one of the reasons people like our Finnish language café: you get to practice Finnish with Finns :) The events are completely free and there is always a native speaker to facilitate the conversation and to help find the right words.

Most people agree that causing unnecessary suffering to animals is wrong. But beyond that, there is surprisingly little agreement. Do animals have rights, or only interests that humans should consider? Is it acceptable to eat animals? Use them in medical research? Keep them as pets? What, if anything, gives humans a higher moral status than other animals? Among other questions, we will consider: * Why is it wrong to kick a dog for fun? * If a trait gives humans a higher moral status than animals, what should we say about humans who lack that trait? * Should we intervene in nature to reduce animal suffering, or should we leave nature alone? * Is the capacity to suffer enough for moral consideration? * Would it be wrong to painlessly kill an animal that had a good life? * Do we owe more to our pets than to wild animals? Join us for an open and respectful discussion of one of the most enduring and challenging questions in ethics: what do we owe animals? Description by ChatGPT

Pay the **5 € board gaming fee** to the bar at the counter when you arrive. You must be at least 18 years old to enter [Arkade](https://www.arkade.fi/). We play in English and the game rules are taught before starting play, unless everyone is already familiar with the game. No previous experience with board gaming required. Despite our RSVP numbers here on Meetup, we almost always have at least 20 people participating weekly. The venue has a great board game library, the host and other players usually bring their own games too: our selection varies weekly. We're a very casual group so you're welcome to arrive early or late and join whatever game is starting up, there is no attendance tracking, or welcoming process. The bar has alcoholic drinks, mocktails, and soft drinks available as well as some snack foods. They've been okay with people ordering food to the bar with meal delivery services. If you are feeling sick, please stay home.

Our monthly PHP meetup. A virtual shindig courtesy of Zoom. Check back here for the details around 6:15 pm

Dear Illinois Prairie PUG members, Thank you to everyone who attended PG DATA 2026! The conference is over, but our meetups are back, and more Postgres content is coming! Those of you who attended our May meetup are already familiar with our new (hopefully permanent) location. For others, please note that we will meet at **Chicago Innovations, 1 W. Monroe**. This time, we are trying a two-talk format. \- Zach Paden will present the talk **Declarative schema management with pgschema.** \- Anna Bailliekove will present the talk **PostGIS Quick Start** More details on talks and speakers coming soon! *Agenda* 5:20 - doors open 5:30 - pizza arrives 6:00 - 6:10 - Hettie D. Opening remarks 6:10- 6:40 - Zach. Declarative schema management with pgschema. 6:45 - 7:10 Anna: PostGIS Quick Start 7:10 - 7:50 - Open discussion and networking 7:50 - 8:00 - Cleanup time and closing **Speaker**: Zach Paden Zach Paden is a tech lead at Symetra with experience ranging from scrappy startups, consulting, to large regulated enterprises. His work spans data platform, analytics and application development where he’s seen more than his fair share of projects get bogged down or catch on fire due to their schema management practices. **Talk Title:** *Declarative schema management with pgschema* **Talk description** Lots of app devs struggle to understand the concept of versioning database migrations, and managing the history of these migrations can become difficult even with existing tools. Using pgschema you can write pure-sql decoratively and let pgschema derive a series of valid online migrations. **Speaker:** Anna Bailliekova Anna Bailliekova has been moving data around professionally for 15 years. Currently a staff engineer XeoMatrix, she focuses on helping organizations mature their data engineering practice, optimization problems, and geospatial data applications. **Talk title:** PostGIS Quick Start **Talk description** PostgreSQL provides rich support for geospatial computing; using transportation examples, we will take a brief tour of these features for those who want to but have been scared to try. *Notes about our new venue*. I am delighted to have an independent venue for the first time since I am hosting the meetups. I hope that this will be our permanent home. And as you all know, with more freedom comes more responsibilities. \- You will notice the change in the RSVP form\. \- We are thankful to our hosts and promise to be responsible\. \- We comply with the [PostgreSQL Code of Conduct](https://www.postgresql.org/about/policies/coc/). \- We do not want to waste food\, so please indicate your dietary preferences\. \- We will not close RSVPs on the morning of the meetup\, but please do your best to RSVP in advance so we can order the appropriate amount of food and drinks\. \- We want to start offering **on-site daycare**. If you indicate on your RSVP that you are planning to use daycare, we will contact you closer to the event with more information. This meetup will be hybrid - please don't forget to indicate whether you are attending in-person or virtually. Thank you, and I look forward to seeing you all at our new location!

Extensions allow developers to customize the editor with new features, integrations, and workflow improvements tailored to their needs. In this session, we’ll cover what extensions are and the different types available, including full extensions written in TypeScript or JavaScript, along with lighter-weight extensions such as color themes, language packs, language support, code snippets, and keymaps. We’ll also look at practical reasons a developer might create an extension, from automating repetitive tasks to adding custom tooling. The session includes a hands-on walkthrough of creating a new extension, testing it locally, and understanding the basic project structure. We’ll close with a brief overview of how extensions are packaged and published to the Visual Studio Marketplace and other distribution options. **YouTube Link** TBD
