Data Mining

**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!

Learn how to paint Mandalas with dots. Painting a mandala is a therapeutic artistic activity that helps you de-stress and calm down. When you paint a mandala, all your attention goes towards maintaining symmetry. You get engrossed in the patterns and get into the flow of creation. If done with an intention, painting a mandala lets you be in and enjoy the present. Membership costs 50kr a year [www.mindfulnesshome.se](https://mindfulnesshome.se) Contact: 070-355 41 91(Emma)

Let's grab a coffee and job hunt together at the library ☕ 💻 Would love to make this a weekly meetup if a few people show up! We meet at the escalators at 9.30, dont forget to cancel if you aren't coming so that people on the waiting list can come. Many people have shown interest and I want to keep the group small so that we can easily find a spot to sit. But you are welcome to create an event of your own, it looks like a lot of people out there want to jobhunt together 😊

**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.

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.

As Head of AI and ML Systems at BioSole International, he focuses on using Cassandra to encode data dependencies that enable reproducible, auditable, and constrained AI reasoning. ​Since the early days of the Cassandra Open Source project, it has been recognized as a critical component in the evolution of telecom infrastructure, particularly mobile core networks. This talk traces how early design constraints shaped architectural decisions in large-scale deployments. It is a story told across three cities in the Persian Gulf, under tight launch timelines, geopolitical complexity, and read-after-write visibility requirements that had an upper limit of 11ms.
