**Meltlake hosts our in-person meetup on the 22nd of April. The location is Meltlake's office at Kansakoulukatu 3.** **Agenda:** \- Game on\! 🎮 Fabric \+ AI 🤖 \+ Power BI 👾 @Meltlake \- Governing Access in Microsoft Fabric: Teemu Multanen If you want to speak in future sessions and have a topic, please do get in touch with either Vesa Tikkanen, Oskari Heikkinen, Heini Ilmarinen or Aleksi Partanen.

At this meetup, we will walk through a practical AI maturity framework for digital product creation. **Product Owner Meetup - Helsinki** is a community where Product Owners come together to celebrate their craft, share real-world experiences, and grow as leaders in their industry. ### **🌱 Join us in the April meetup about AI maturity in product creation** AI is already affecting how product teams work, but many teams still struggle with the same questions: * Where are we today? * Where is AI genuinely useful? * And what should we do next? At this meetup, we will walk through a practical AI maturity framework for digital product creation in e-commerce. It helps product teams assess how AI shows up in discovery, prioritisation, decision-making, delivery, and customer experience 👉…and identify the next improvement area. You will get a concrete way to discuss AI maturity with your team, spot the most relevant opportunities, and avoid getting stuck between experimentation and real adoption. Expect a practical session and an honest discussion, not AI buzzwords. #### **Speakers** **🎤 Okko Ojala, Senior Architect, Nitor** Introducing the AI Maturity Playbook and how teams can use it to start the conversation around beneficial use of AI in product development **🎤Joakim Sandström, Senior Architect, Nitor** Sharing lessons from applying the framework with Finnair and what happened when the framework met real product work 📍 *Where:* **Nitor Office, Aleksanterinkatu** 46, 6th floor (next to Mummotunneli) 🕕 *When:* **Wednesday, 22nd of April, from 17:30 to 19:30** 🍪 *Bonus:* **Snacks, drinks, and great company!** Through inspiring talks, hands-on discussions, and opportunities to connect with peers, we aim to value and highlight the role of the Product Owner to one of innovation, pride, and strategic impact. Each session brings together practical insights from industry leaders with first-person, real-life stories from local and global product professionals who have tackled challenges and achieved breakthroughs. Whether you’re fine-tuning stakeholder management, mastering prioritisation, or seeking inspiration, you’ll find a welcoming space to learn, collaborate, and advance your skills. Join us in shaping a movement where Product Owners are recognised as key drivers of outcome orientation, innovation and value, transforming the profession into a globally celebrated craft. 📍Please note: the downstairs exterior doors lock at **17:00**. If you arrive after this, just ring the doorbell and we will let you in. The event begins at **17:30**.

This will be our last meeting on *Nature's God: The Heretical Origins of the American Republic*, by Matthew Stewart. For this meeting, please read the last two chapters: Chapter 7: The Empire of Reason Chapter 8: The Religion of Freedom **Where did the ideas come from that became the cornerstone of American democracy?** America’s founders intended to liberate us not just from one king but from the ghostly tyranny of supernatural religion. Drawing deeply on the study of European philosophy, Matthew Stewart brilliantly tracks the ancient, pagan, and continental ideas from which America’s revolutionaries drew their inspiration. In the writings of Spinoza, Lucretius, and other great philosophers, Stewart recovers the true meanings of “Nature’s God,” “the pursuit of happiness,” and the radical political theory with which the American experiment in self-government began. [LINK](https://a.co/d/bkTWJNb) I recommend using an AI tool like ChatGPT to ask these questions: 1. What does Matthew Stewart say about the empire of reason in his book Nature's God? 2. What does Matthew Stewart say about the religion of freedom? I hope to see you there! Fred

We invite you to an in-person session in Seattle exploring the real impact of AI on knowledge-driven industries — from shifting economics and the disruption of traditional SaaS and consulting models to where organizations can still build lasting competitive advantage. As AI platforms like ChatGPT, Claude, and Gemini continue to redefine how work gets done, organizations face a critical question: how can they adapt, remain competitive, and create lasting value? We’ll discuss practical strategies for integrating AI while preserving human expertise, along with actionable approaches to upskilling teams for an AI-driven workplace. Drawing on real-world experience from training thousands of professionals and deploying AI solutions, this session will provide clear, applicable insights for today’s evolving landscape. Following a short presentation, the session will open into an interactive discussion where attendees can share perspectives and explore key questions around the evolving role of humans, organizational adaptation, and staying competitive in an AI-first world. **Who should attend:** • Executives and managers in SaaS, consulting, and knowledge-driven organizations • Professionals exploring AI upskilling and workforce transformation • Anyone interested in the future of AI and knowledge work 📍 **Location:** Data Science Dojo, 5010 148th Ave NE, Suite 200A, Redmond, WA, United States 🔗 **Google Maps:** [https://lnkd.in/d8WA-yNc](https://lnkd.in/d8WA-yNc) **💻 Online Access:** A livestream will be available for those unable to attend in person; however, the full interactive experience is reserved for in-person participants.

[Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“Doom and Dinosaurs,”** a look at how mass extinctions shaped the dinosaurs and what research on these events tells us about Earth life’s long-term prospects, with Ian Wilenzik, paleontologist and visiting assistant professor of biology at George Washington University. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/nv-dino-doom](https://events.ticketleap.com/tickets/profsandpints/nv-dino-doom) .] Pity the poor dinosaurs. They lacked both scientific research to help deal with potential environmental catastrophes and places where they could have a beer and discuss it. You, on the other hand, have the opportunity to come to Profs and Pints to hear a fascinating talk on the impact of mass extinctions on dinosaur evolution and what research on dinosaurs tells us about biodiversity and Earth’s current biodiversity crisis. Dr. Ian Wilenzik, who has studied and taught courses on dinosaur evolution, population spread, and extinction, will leave you with a greater appreciation of the resilience of life on earth and how we’re both the product and source of biologically catastrophic events. Many of us are familiar with how a big meteor impact about 66 million years ago wiped out the Earth’s dinosaur population, leaving us only with their feathered descendants, birds. Less well known is how the Earth actually has undergone five periods of mass extinction that wiped out nearly all life, and how dinosaurs arose from one and endured another—both caused by volcanic activity—before meeting their match in the third. To ground his discussion, Dr. Wilenzik will talk about how we study mass extinctions by looking for geologic evidence of volcanic activity, meteoric blasts, and other catastrophic activity and of gaps in the fossil record after them. He’ll also discuss what makes a dinosaur a dinosaur, describing their distinct anatomical features. He’ll talk about how they and other forms of life evolved over long periods of time and were affected by extinction events. We’ll look at how the meteor-caused mass extinction that wiped out dinosaurs at the end of the Cretaceous paved the way for the rise of mammals and the emergence of primates, and, eventually, us. Looking ahead to future mass extinctions and what might survive them, we’ll talk about how that plant you forget to water might have the last laugh, as well as why crocodiles might be around a while. (Doors: $17, or $15 with a student ID. Listed time is for doors. The talk starts 30 minutes later.)

[Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“The Twister Talk,”** on tornadoes and advances in our understanding of them, with Jeffrey Halverson, professor of geography and environmental systems at the University of Maryland Baltimore County and author of *An Introduction to Severe Storms and Hazardous Weather.* [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/nv-twister-talk](https://events.ticketleap.com/tickets/profsandpints/nv-twister-talk) .] Springtime brings tornado outbreaks and devastation across the United States. The good news for those of us who anxiously eye the skies: Tornado science is rapidly evolving and improving, as are the means by which we detect funnel clouds and warn of their approach. Get up to speed with what’s known about tornadoes with the help of Dr. Jeffery Halverson, a severe storm expert with the *Washington Post* Capital Weather Gang who previously has given excellent Profs and Pints talks on hurricanes and snowstorms. He’ll describe how, with the help of research conducted by tornado hunters, meteorologists are using ever more sophisticated computer simulations and datasets to try to “crack the code” when it comes to how and where tornadoes form. We’ll look at how science teams wielding Portable Doppler Radars on small trucks are learning that tornado wind speeds are much stronger than once presumed. We’ll consider how decades of data are changing how we think about “Tornado Alley,” and we’ll review what’s known about the relationship between tornadoes and climate change. Professor Halverson will conclude by discussing the technological strides being made in terms of tornado warning and detection, and how tornado scientists are teaming up with social scientists to gain a better understanding of what leaves us vulnerable to natural hazards. (Doors: $17, or $15 with a student ID. Listed time is for doors. The talk starts 30 minutes later.)

Members of the public are invited to view the wonders of the universe through the telescopes of NOVAC volunteers at the Smithsonian's Udvar-Hazy Center in Chantilly, VA. You do not need to be a member of the club or own any astronomical equipment to attend. Telescopes will be provided by the Smithsonian and pre-approved members of the NOVAC. No other personal telescopes are permitted at the event. The event will take place on the bus parking lot of the museum. **Please park your vehicle at the south end of the main visitors lot and follow signs and red lights to the observing site. As a reminder, parking during the event is free.** Have a cosmic question? One of NOVAC's astronomers or museum staff will be happy to help you. As the sky gets dark, be prepared to enjoy the wonders of the night sky! Don't forget to dress warmly. Please check the weather forecast. For lighting, cover a flashlight in red cellophane (the darker the better). Bring along water to keep hydrated. Note: This outdoor event is weather-dependent and may be cancelled because of significant cloud cover or precipitation.
