Data Science using R

This is a group for meeting new people, eating brunch, and having discussions about science, life, philosophy, politics, and people. Anybody is free to join, and we charge no fees. This discussion group aims to have the absolute minimal level of structure necessary to ensure the conversation remains engaging to the majority of people present. In particular, we \*don't\* have fixed order of speaking or timed statements. So far, the balance we've struck is enforcing hand raising when conversation gets intense in order to minimize interruption, and to give the chair (me!) the power to occasionally call a snap election on the conversation topic.

**ATTENTION: the event will take place on the Donauinsel!** Are you ready to mingle and make new friends? A YouTuber visited our event 😃 [[3-minute video](https://www.youtube.com/watch?v=9eG1dYro4u8)] **"How does it work?"** We talk in small groups and rotate every \~10 minutes. Tip: for a more fun conversation, introduce yourself not with your job, but with your interests/hobbies... and see what happens ;) **"Can I bring friends?"** Great idea! 😃 **"Can I give you feedback about the event?"** Yes, keep the ideas coming!

Thank you for visiting this event page! * Are you an advanced badminton player? If yes - WELCOME! * The earlier you sign up, the bigger your chance to reserve a place - once 10 players have signed up already, you move to the waiting list. * Once the waiting list has 3 or more members, I will try to book an additional court, but no guarantees. I need to close the registration 24h before the event as I will then have to decide whether to cancel any court due to a shortage of players. The fee per player will be €10.00 for 2 hours. This will also cover the feather shuttles used during play. Please be on time as a curtesy to the other players. In addition, if you are on the players' list and don't come (i.e. no show), you will be automatically excluded from this group.

For English scroll down. Die Donauinsel – zwischen 1972 und 1988 gemeinsam mit der Neuen Donau erbaut, um Wien endgültig vor verheerenden Hochwässern zu schützen – ist heute aus dem Stadtbild nicht mehr wegzudenken. Dass an warmen Sommertagen auf der mehr als 21 Kilometer langen und bis zu 250 Meter breiten Insel einmal mehr als 200.000 Personen täglich unterwegs sein würden, war beim politischen Startschuss für das Projekt im Jahr 1969 allerdings weder geplant noch vorhersehbar. Ursprünglich als rein technisches Hochwasserschutzprojekt konzipiert und politisch höchst umstritten, entwickelte sich die Donauinsel erst im Lauf von mehr als 30 Jahren Planungs- und Bauzeit zu einem vielfältigen Natur- und Erholungsraum am Wasser. Die Ausstellung im Wien Museum beleuchtet die Geschichte und Gegenwart dieser besonderen Landschaft, die heute zu den wichtigsten Freiräumen in der Stadt zählt und Stadtbewohner:innen unterschiedlichsten Alters und diversester Herkunft für eine Vielzahl von Aktivitäten dient. Unter vielen anderen Objekten sind ein elf Meter langes historisches Donauinsel-Modell, ein mobiler Inselkiosk sowie aktuelle Foto- und Filmarbeiten von Klaus Pichler, Elodie Grethen und Dariusz Kowalski zu sehen. Wir treffen uns um 15:00 Uhr vor dem Eingang des Wien Museum, Karlsplatz 8, 1040 Wien. Jeden 1. Sonntag im Monat ist der Eintritt in die Sonderausstellungen des Wien Museum kostenlos. Nach dem Ausstellungsbesuch gehen wir in eines der nahegelegenen Cafés. ***English:*** The Danube Island – built between 1972 and 1988 along with the New Danube to protect Vienna from devastating floods – has become an integral part of the city’s identity. Back in 1969, when the project was launched, no one imagined that more than 200,000 people would spend beautiful summer days on this stretch of land, 13 miles long and up to 800 feet wide. What began as a purely technical and highly controversial flood-control project gradually transformed over more than 30 years of planning and construction into a diverse natural and recreational space on the water. The Wien Museum exhibition explores both the history and present of this extraordinary landscape, which today is one of Vienna’s most important open spaces. The island is used by residents of all ages and backgrounds for countless activities. Among many other objects, a 36-foot-long historic model of the Danube Island, a food cart, as well as recent photographic and film works by artists Klaus Pichler, Elodie Grethen, and Dariusz Kowalski are on display. We meet at 3. p.m. at the entrance of the Wien Museum, Karlsplatz 8, 1040 Wien. On the first Sunday of every month, admission to the Wien Museum’s special exhibitions is free. After visiting the Exhibition we will have a drink together in a café nearby.

Also, bring clean indoor sports shoes, your racket and a water bottle with you. There is a drinking fountain available if you need to replenish your bottle.

Highlights and Hidden Gems in SQL Server 2025 With so much emphasis on cloud data platforms and AI these days, SQL people can feel left behind by all the marketing hype. SQL Server 2025 was officially released in November of 2025, though, and contains a ton of improvements that will make our SQL Server deployments a bit faster, better, and more secure. There are even more improvements tucked into the release that never made a marketing blog or press release that you'll likely be learning about for the first time in this session! Join this session to learn about what makes your high availability a little more available, your performance a bit more performant, and your database more developer and app-friendly. Come spend an hour with SQL people talking SQL Server 2025 – the good, the "not quite ready for prime time", and the hidden awesomeness.

**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.

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.
