Fulfillment. Joy. – Do you know what it is? Do you feel it now? Many of us are living lives that have “just sort of happened”. We had a dream, a vision (maybe we still do) for what we wanted our lives to look like. Somewhere along the way, life took over and something else ended up happening. We made decisions, took a turn down a path, and now our life isn’t what we thought it would be. Or we’re living someone else’s life. Maybe it’s what our parent’s wanted for us. What we believe our partner or a potential partner might want. Or maybe it’s what we believe we need to do and have to be happy. I was one of these people. My life checked all the boxes for what I thought I needed in order to be happy. And still, I wasn’t. Join me for a coffee talk on what it means to live a Life By Design. Where your choices are deliberate and based on your authentic, true self. What you have to let go off to achieve this (hint: the notion that vulnerability is a weakness and feelings of fear and guilt) and who you will become in the process.

We are a group of people meeting on Tuesdays to socialize around cooking and eating together. Usually around 40-50 people. Many are international students, but also other people join. The foodclub exist independent of Meetup, we invite you because we have room for a few more people. The food is vegan and made from donated leftover veggies from a local greengrocery. The place has originally hosted leftwing activist groups, and many of the people joining are also involved in political groups. If you want to join for chopping and cooking, we will be doing that from 3 to 6 pm. It is possible to join part of the time. From 6 to 8pm we are serving food. Donation around 30 kroner. If you are helping out some hours, chopping, cooking or cleaning, you can eat for free. From 8 to 9 - 9:30 pm we are cleaning up the place. We hope to see you in our lovely foodclub <3

**Get ready for the next edition of the Copenhagen Data Engineering Meetup!** On the 18th of February, we are gathering at **Unity’s** Copenhagen headquarters for an evening dedicated to fine-tuning our engines and navigating the future of open data ecosystems. Whether you’re looking to squeeze every ounce of performance out of your Spark jobs or trying to make sense of the rapidly evolving catalog landscape, this is an event you won't want to miss. ### The Lineup We have two deep-dive sessions featuring experts from the front lines of data platform engineering: **Spark Tuning & Best Practices: From Theory to Production-Ready Performance** *Asaf Sneh (Unity)* Moving from a Spark job that "just works" to one that is production-hardened and cost-efficient is no small feat. Asaf will take us through the journey of Spark optimization, bridging the gap between theoretical best practices and the realities of running high-performance workloads at scale within Unity. **Graduating Class of 2026? The Current State of Apache Polaris (incubating)** *William Martin (Dremio)* As the industry moves toward open table formats, the question of "who manages the metadata" has never been more relevant. William will give us an insider look at Apache Polaris. With it being 2026, we’ll explore its progress through the Apache incubator, its role in the Iceberg ecosystem, and whether it’s ready to become the "valedictorian" of your data architecture. And, of course, a Data Engineering meetup wouldn't be complete without the chance to talk shop over a good meal. **Dinner and drinks** will be provided by our generous sponsors, **Unity** and **Dremio**. *** ### 📍 Location & Venue The event is hosted by **Unity** at their offices in Copenhagen. *Stay tuned for specific entry instructions closer to the date.* ### Agenda * **18:00:** People Arriving + Networking * **18:15:** Introduction * **18:20:** Spark Tuning & Best Practices (Asaf Sneh, Unity) * **19:00:** Dinner & Drinks * **19:30:** The Current State of Apache Polaris (William Martin, Dremio) * **20:10:** Networking & Wrap-up We look forward to seeing the community come together for another night of great technical discussions!

**Truth, Trust, Technology, and a World You Can’t Quite Verify** We’re entering a time where seeing is no longer believing. AI can generate voices, faces, videos, articles—and entire narratives—almost indistinguishable from reality. When everything can be fabricated perfectly, what happens to truth, trust, and our shared sense of what’s real? This isn’t a media literacy workshop or a tech lecture. It’s a philosophical conversation about reality itself in an age of artificial generation. *** **Topics we’ll touch on:** * When AI can fake anything, does “truth” still exist in a meaningful way? * Deepfakes, synthetic news, and the erosion of shared facts * Is reality becoming personalized—different for each of us? * Who decides what is real: humans, algorithms, platforms, or states? * Can democracy survive without a common understanding of truth? * Are we heading toward radical skepticism—or digital authoritarianism? * And finally… how do we live well when certainty itself starts to dissolve? Casual discussion. No technical background needed. Just curiosity, openness, and a willingness to question what you think you know. Whether you feel worried, intrigued, or strangely detached from it all—you’re not alone. Let’s question the images, the stories—and maybe even our own assumptions about reality.

Stop by and meet people in a positive and save space, very Friday at 8:30 pm just after our abstract workshop we start our **Speed Portrait and Cocktails event.** Before continuing your journey into the vibrant Copenhagen we invite you for a creative stop, to develop some quality interaction and create a truly hygge atmosphere in an artistic space. Set in a contemporary art gallery turned into a creative studio for the night, our **Speed portrait & cocktails** event blends with the city night life adding to Copenhagen artistic vibe and cozy atmosphere. An event that mixes caribbean hospitality, minimal aesthetic and Copenhagen coziness. As well we offer locals and temporary locals an artistic retreat from the intensity of the city. Note: Some materials are free but not the drinks.

**Abstract:** The Advanced Photon Source (APS) is an X-ray light source at Argonne National Laboratory where researchers perform imaging, diffraction and spectroscopy experiments at 68 specialized beamlines. APS recently completed a major upgrade that made it the brightest synchrotron in the world and upgraded many of the beamlines to take advantage of the dramatically brighter, more coherent beam. These new capabilities are increasing the facility’s raw data production from <10 PB/year before the upgrade to >100 PB/year once all instruments are back online. To meet this data challenge, the APS Beamline Data Pipeline project team is partnering with beamline staff to develop and deploy science data pipelines that use a common set of open-source software tools (many written in Python) to link instruments with the Polaris supercomputer at the Argonne Leadership Computing Facility (ALCF) for data processing. This talk will describe the APS data systems, our file-based and streaming pipeline templates, and some of the open-source software we use to extract scientific insights from beamline data. **Audience Takeaway:** Open source Python data acquisition and analysis tools are ubiquitous at the APS. Many of the packages that are mentioned can be found at [https://github.com/AdvancedPhotonSource](https://github.com/AdvancedPhotonSource). This is a *hybrid* event. To attend online, join us on Zoom here at 6pm: [https://numfocus-org.zoom.us/j/89399976851?pwd=UEgMUZXdYmKdK1x1dIPL6hwUYnp7NW.1](https://numfocus-org.zoom.us/j/89399976851?pwd=UEgMUZXdYmKdK1x1dIPL6hwUYnp7NW.1) **Sponsor**: Grainger will provide the meeting site, as well as snacks for the onsite participants. * **Address:** 222 W Merchandise Mart Plaza, 18th Floor, Chicago, IL 60654 * **Grainger's Overview:** W.W.
