**Bitcoin Meetup met Crazy Pool!** Deze maand organiseren we iets leuks: voorafgaand aan de meetup (voor wie dat wil) spelen we Crazy Pool bij Timestamp op de Korenmarkt. Crazy Pool lijkt op minigolf, maar je speelt het met een keu en een bal die je door verschillende obstakels moet stoten. De speeltijd is ongeveer 45 minuten. Aansluitend eten we bij Flor Fina. Je kunt ook na het diner aansluiten als je alleen voor een drankje wilt komen. De Bitcoin Meetup is geschikt voor zowel beginners als ervaren bitcoiners. Stel je vragen en praat mee over de nieuwste ontwikkelingen in de wereld van bitcoin. Wil je meedoen met Crazy Pool of mee-eten? Laat het ons even weten, dan houden we daar rekening mee bij de reservering. * 16:30 — Crazy Pool @ Timestamp (Korenmarkt) * 17:30 — Diner @ Flor Fina (Korenmarkt) * 19:30 — Drinks @ Flor Fina (Korenmarkt) ## English Bitcoin Meetup with Crazy Pool! This month we’re doing something fun: before the meetup (for those who want to join) we’ll play Crazy Pool at Timestamp on Korenmarkt.

You can also join later if you only want to come for drinks. The Bitcoin Meetup is suitable for both beginners and experienced bitcoiners. Ask your questions and join the conversation about the latest developments in the world of bitcoin. Would you like to play Crazy Pool or join us for dinner?

Hi all, We’re back at Mick O’Connells and ready for another strong evening! We’ve got our own space again. Walk in, turn right at the bar, head past the dart boards, and you’ll find us in the side room. We've introduced a simple rotating format that gives you the chance to actually speak with everyone in the room. Short, focused conversations, good energy, and a lot more fun than it sounds. We’ll throw in a few conversation topics to get things going, but how you use the evening is entirely up to you. Come with intention, or don’t. Talk business, find clients, meet future partners, make friends, or just unwind with people who get it. We’re all building something, and we all have to roll with the punches. Only rule: you’re an entrepreneur, freelancer, or about to become one within the next 3 months. If not… the clock starts now ;) Try to arrive on time so we can kick things off properly. Can't find us? Look for the grey Gnome. He’ll guide you better than any sign ever could. See you there.

**📣** Welcome to **our second meetup in 2026!** Missed last meetup? Then its important you know that the Green Software Foundation and Sustainable IT Netherlands meetups, merged into one: **Sustainable IT Action NL!** Our mission is still to build connections around sustainable IT, exchanging ideas in a space for learning - and from there inspiring our members to take action. **🌿** We’re excited to gather peers who care about green, efficient, and responsible cloud practices on **April 23rd**, kindly hosted by **GreenPT** in Utrecht. **⏳ Time schedule** 17:30 – 18:00 Welcome 18:00 – 18:30 Vegetarian bites & networking 18:30 – 18:45 Kick-off & community introductions 18:45 – 19:15 Measuring the environmental impact of Google's AI - interactive explainer – Ozan Ogreden 19:15 – 19:45 Maryse Meinen– Holistic Digital Sustainability 19:45 – 20:00 Pitches 20:00 – 20:45 Drinks & networking **📍** 📍 **Location:** Plompetorengracht 4, Utrecht. GreenPT **❗ Capacity is limited to 50 participants, so please register early.** **✏️ Title: Measuring the environmental impact of Google's AI - interactive explainer** **💡 Speaker: Ozan Ogreden** **🍃 Abstract:** I built an "interactive explainer" that reproduces Google's methodology from Elsworth et al. (Measuring the environmental impact of delivering AI at Google Scale, Aug 2025, https://arxiv.org/abs/2508.15734). I'd like to share the explainer and my observations with the community. What stands out to me is a striking analytical (or rhetorical?) choice by Google team, which seems to be leading to a downward bias in headline-reported figures of their work. With the community, I'd like to attempt at two goals. One of them is a "narrow-minded goal", trying to find a charitable interpretation of what may have motivated Google's choices (specifically in the discussion related to measuring environmental impact of LLMs). The second is a goal with a more important perspective: Given our discussion, what's the best use of our time to move the needle in sustainable IT? *Ozan works at GreenPT:* GreenPT is a GPT-powered chat platform, and robust API, trusted by governments, businesses, privacy-focused organizations, and developers. Running on renewable energy and hosted in Europe for strict data protection, GreenPT gives you and your team the answers you need with a clear conscience and total transparency.
