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. The coffee is good too ☕😋🇦🇹 Tervetuloa!

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.

【IMPORTANT SUMMARY】 * The purpose of social games is to know some people, do some exercise and enjoy the games together with others. Winning and getting points is not the focus of this session. Please play with consideration to your opponents' level. * Please purchase your slot through this link [https://7538e9.myshopify.com/](https://7538e9.myshopify.com/) 【SIGN-UP SYSTEM】 * Please sign up and pay through this link. [https://7538e9.myshopify.com/products/social-game](https://7538e9.myshopify.com/products/social-game) * We don't use the signup system on Meetup.com anymore. (Neither the waiting list) * It says this event is full on this meetup page, because I didn't open any slots here for you to sign up. You have to check this [sign-up page](https://7538e9.myshopify.com/products/social-game) to see if there is still a slot available there. * The background of using an external sign-up and payment system is because Meetup.com introduced a service fee to increase 21% of the fee in May 2023, and we want to reduce this cost. 【FEE and REFUND POLICY】 * Fee includes courts and plastic shuttles. Please sign up and pay before you come. NO refund if you do not cancel until 48 hours before the event. * Racket: bring one or rent one at the counter. * You can put a comment to sell your slot after the deadline of refund, or sell your slot in our whatsapp group. * No matter the reason is sickness, accident or anything, the group or I will not afford the cost caused by your absence. * Of course you CAN'T ask me, "Can I sign up for free for next week because I didn't come to use my slot this week?". Please remember, the court booked for you was there and it costs money. The court doesn't simply become "free of charge", just because you didn't come to use it. 【COMMUNICATION】 * Communication: our whatsapp group [https://chat.whatsapp.com/JJQbJlisbcj5YDnlcSu347](https://chat.whatsapp.com/JJQbJlisbcj5YDnlcSu347) * There are too many spams, so I only accept +358 number to join whatsapp group. Numbers from other countries will all be rejected. 【OTHERS】 * Please always keep 1 meter away from those courts where people are playing. Never step into the corners of other courts! If I see you do this, I probably will yell at you! * If you have some questions, you can put your questions in the comments on the event page. People will respond. * We play double games to 21 points. After each game, please let those who are waiting to play. Feel free to play with whoever you want, but please avoid playing with the same people all the time. * If you are new to badminton, please Google basic badminton rules in advance. Serve rules, double rules and point counting rules. You are always welcome to ask anyone in our group. Most of our members are more than happy to help you. * Badminton activity is organized for non-profit purpose, but I take a small fee for my work. * Want to restring your racket? I can do restring for you. €24 including the string. Please get contact with Ken.

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

Let's head outside and play in the sunshine Gather near the outdoor piano in the Töölonlahden Kesäpuisto. Bring an instrument, something to sit on, a tablet (or small laptop) if you have one, something to drink, sunscreen, etc ... and let's have a proper session playing our favorite songs in the sunshine. Whether you are a beginner, or an experienced player … or perhaps you just like to sing along … come and join use for a sing-a-long / play-a-long session. We will then start playing and everyone can join in. If you want to improvise over the song while we are playing, go ahead!!! Bring your uke, guitar, or any other instrument … or just yourself. Small amps are welcome. All ages welcome. We will cancel if it rains

Let's get together and listen to **[Eric Rico](https://www.linkedin.com/in/ericrico/)** from Unity3D (**From Joints to Gestures: Reading Hands in Unity**). A hand tracker gives you joints, not a gesture. This talk shows how you get from raw joints to a "thumbs-up" in Unity: the pipeline that cleans up the data, how a gesture becomes a few 0-to-1 values within tolerance, and why orientation matters as much as finger shape. Includes a live demo of tuning gesture thresholds. Eric also runs the **[Columbus Unity User Group](https://www.meetup.com/columbus-unity-user-group/)**. Check it out! ***Bring your laptop and expect to write some (non-AI-generated) code!*** Food and drinks will be available. **LOCATION:** 6515 Longshore Loop, Suite 300, Dublin, OH 43017 **FREE PARKING:** 6725 Longshore Street, Dublin, OH 43017

The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** *Customize the IDE: Building Extensions for Visual Studio Code* Visual Studio Code is one of the most widely used development environments today, and much of its flexibility comes from its extension ecosystem. 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
