It's that time again! Let's keep our yearly tradition going by celebrating the 4th of July with a chill picnic at the Kinnekswiss Parc in Luxembourg city center! Feel free to bring along stuff to share, or not! Sharing food and drinks isn't mandatory, although if you have a signature dish or drink others will surely appreciate it too... :) DO be sure to bring your own blanket or towel, food and drinks, and a hat/sunglasses/sunblock! If you have any outdoor-friendly games, bring 'em along as well! I will bring some small food things for us to share, some disposable cutlery, a small speaker, and a cooler. As the day approaches we can use the comments section or group chat to plan pot-luck food, games, etc. Join when you can and leave when you need, people will be coming and going all afternoon! Please provide me your phone number in a private message if I do not already have it. This is only so I can create a WhatsApp group to share the picnic location on the day. If you do not wish to be in that chat, please let me know and I will send you our location privately on the day. I will show up a while before the start time to find a good spot and claim some space, and I expect us to wrap up the party in the early evening :) Can't wait to see you there!

Outdoor calisthenics workouts are a fantastic way to build strength, improve fitness, and enjoy the great outdoors 😁🦾 Calisthenics is a form of strength training that uses the resistance of your body and gravity to help strengthen your muscles and improve your coordination, endurance, and mobility. It’s a workout that relies on body weight with little or no equipment. In fact, almost all common bodyweight exercises are considered calisthenics exercises. Some examples include: - airsquats - pushups - pullups - frogstand -handstand -musclup -backlever aso 😁 Whether you’re a beginner or an advanced athlete, calisthenics provides a holistic approach to fitness. 🏋️‍♂️💪

Hello Friends! It's been a while that we did this hike, it's the short version of "walking home from Lintgen", but still almost 16km. We're going to take the train to Lorentzweiler and walk all the way to Dommeldange. After the first 2km took us quite steep up, the first short break will be at the "Neolithikum", a rebuild of a prehistoric house, inspired by local archeological findings. During the hike, there will be a nice viewpoint over the valley between Luxembourg and Mersch, a chapel in the rocks, and a Roman underground water canal, which is hopefully open for visit, otherwise we will at least have a source with ice cold water to cool our arms and heads At this site, "Raschpetzer", after around 9km, we will do our lunch break. 6-7km later, we will end up in Dommeldange, where we can have a coffee or some cold beers at "Am Chalet" **Meeting Point:** We will meet at the train station in Lorentzweiler and start right after the train arrived. https://maps.app.goo.gl/Lr7ppZzkQuV91o6u7 **Public Transport:** You can take train RB 3609, leaving Gare Centrale at 09:53, platform 4cd (this may change until then, please check the time table at the train station). I will hop on that train in Dommeldange. Note: It's not a loop, if you come by car to Lorentzweiler, you need to take the train back there from Dommeldange after the hike. **Carpool:** If you come from a different direction and need to drive, maybe you can offer a seat to a friendly co-hiker. Here's the link to the carpool: https://groupcarpool.com/t/w3irxc Please indicate the pickup location and whether you want to drive to Lorentzweiler directly or to a train station from where you take the train. **Please note:** It's tick season. Be careful, use some repellent product, and check yourself after the hike. As usual, the hike is at your own risk, and please take enough water for yourself. Looking forward to hiking with you! Jens

You read that right, our group will be celebrating the 4th of July all weekend long! Part two will be at Kantin in Dudelange, where the team is already planning some awesome food, entertainment, and games for us all in Independence Day spirit. On the agenda is: \* Authentic Texas BBQ buffet featuring smoked USDA Prime brisket, pork ribs, pulled pork, buffalo wings, sausages, and traditional American side dishes \* Award-winning craft beers from Twisted Cat Brewery on-tap plus frozen margaritas, bourbon cocktails, homemade lemonades, and milkshakes \* Cornhole and Beer Pong \* American-themed music all day \* Best American Outfit contest with prizes The event is family-friendly, and Kantin is dog-friendly, so everyone is invited! I will arrive at 14:00 that day, but if you want to come later, no worries, just let me know! I am asking for a PayPal fee simply as a deposit to guarantee your seat and fight against no-shows. When you arrive at Kantin, I will reimburse your fee and we will all pay our own way at the end as usual. If you ghost us, we reserve the right to buy BBQ with your money! Thanks for understanding and let me know if PayPal is an issue for you :) Hope to see you there!

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. 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.
