#This meetup is around a third-party organizer (Focus Filmtheater): you can either purchase your ticket online or right before the session. **Seats are numbered**# **Title**: L'engloutie **Language**: French **Subtitles**: English **Length**: 98 min **Director**: Louise Hémon **More info**: https://www.focusarnhem.nl/agenda/lengloutie-2/ **Ticket link**: https://www.focusarnhem.nl/tickets/143042/ **Synopsis**: On a stormy night in 1899, Aimée, a young republican schoolteacher, arrives in a snowbound hamlet on the remote edges of the French Alps. Despite the villagers’ mistrust, she’s determined to shed light on what she sees as their dark beliefs. As she gradually becomes part of the community, a sensual vertigo begins to grow within her. Until the day an avalanche claims the life of a first mountain dweller. **How it works**: I will be at Focus around 18:30, where we can meet before the movie starts. You can message me to find us. Screening starts at 19:00. After the movie, we can have a drink together. Hope to see you soon!

Stel je voor: een avond waar karton en ideeën vonken geven. Waar pionnen geen plastic zijn, maar gesprekstarters. Waar een prototype geen “bijna-af” product is, maar een laboratorium op tafel. Spellenmaakgilde en The Serious Gamers bundelen hun krachten en brengen het beste van twee werelden samen. **Het Spellenmaakgilde** is een community voor makers van bord- en kaartspellen: testen, schaven, opnieuw proberen. Idee > prototype > feedback > beter spel. **The Serious Gamers** richt zich op spellen die meer doen dan vermaken: ze zetten spel in als middel om te leren, gedrag te spiegelen en gesprekken op gang te brengen op de werkvloer. Op **woensdagavond 22 april** draait alles om Serious Game Prototypes. Heb jij een spel in ontwikkeling dat iets wil blootleggen, oefenen of veranderen? * Een spel dat teams helpt elkaar écht te begrijpen? * Een spel dat mensen kritisch laat kijken naar hun werk of naar de maatschappij? Dan is dit jouw moment. We bouwen samen aan spellen die niet alleen leuk zijn, maar iets in beweging zetten. 📍 Locatie: **Café Oproer in Utrecht** 🕖 Tijd: **19.00 - 22.00\*** 💶 Deelname: **gratis** 🎲 Doel: **testen, leren, aanscherpen** Neem je prototype mee. Of kom spelen en feedback geven. Maar kom vooral! Meld je aan en schuif aan tafel. \*Aan tafel kan ook voor avondeten, de locatie is vanaf de middag geopend. Dus kom er gerust (op eigen kosten) wat eten vooraf.

Hi people! 👋 Tonight we'll take a seat and chill out at The 5th, the bar/restaurant of the Stayokay hostel. Come join us and don't shy away from making friends with us, we're a kind bunch! 😄 This meetup is expected to start at 9pm and end at 11pm. See you there! 🌈❤️

Hi all! 🙂 On Wednesdays we welcome you to practice languages! If you want to practice a specific (uncommon) language, please send us a message so we can find some conversation partners for you on our mailing list! We hope to see you in Café Marktzicht! In the last year we had tables for the following languages: * Dutch * English * French * Italian * Spanish * Turkish\* * German\* * Portuguese\* * Danish\* * Norwegian\* * Russian\* * Arabic\* * Chinese\*\* * Japanese\*\* * Indonesian\*\* * * Most likely, but not every week present. \*\* - Rather rare ;-) If your language is not in this list, please let us know! We have a large database of Language Cafe visitors speaking 56 different languages! We might be able to connect you with a person that does speak the language you want to practice. In case you are not in our database yet, please use this form: http://goo.gl/forms/oSCn9Dn8m8

It is a safe place 🙂✨ Everyone plays the game in the way they feel the most comfortable. The event price is 10 euros, which includes one drink. Host gets 5 for the preparation of the myths and prompts, the rest goes to the establishment where the event is hosted.

Give your still good laptop a second life instead of ditching it because Windows 11 says it is no good... Or you heard Linux is cool. If you have a backup of your data, that is great, else indicate that you do not, so we can help you. Do so in an extra message or to m10@m10tech.nl, else I don't receive your information. Geef je laptop die het nog prima doet een tweede kans in plaats van hem af te schrijven omdat Window 11 dat zegt... Of omdat je hoorde dat Linux gaaf is. Als je al een backup van je data hebt gemaakt is dat perfect. Of verwacht je dat wij dat doen? In dat geval graag aangeven hoe vol je harde schijf nu is... Doe dat in een extra bericht of aan m10@m10tech.nl, want de info komt anders niet door.

This session focuses on **Sparse and Ranking in Modern Retrieval**, featuring two speakers: **Simon Lupart** from University of Amsterdam and **Chuan Meng** from University of Edinburgh. **Location:** Science Park 904, Room C3.161 **Date**: Friday, April 24 **Time**: 16:00-17:00 **Zoom** **link**: [https://uva-live.zoom.us/j/65011610507](https://uva-live.zoom.us/j/65011610507) Details below: **Speaker #1**: **Simon Lupart** from University of Amsterdam **Title:** On the Challenges and Opportunities of Learned Sparse Retrieval for Code **Abstract:** Retrieval over large codebases is a key component of modern LLM-based software engineering systems. Existing approaches predominantly rely on dense embedding models, while learned sparse retrieval (LSR) remains largely unexplored for code. However, applying sparse retrieval to code is challenging due to subword fragmentation, semantic gaps between natural-language queries and code, diversity of programming languages and sub-tasks, and the length of code documents, which can harm sparsity and latency. We introduce SPLADE-Code, the first large-scale family of learned sparse retrieval models specialized for code retrieval (600M-8B parameters). Despite a lightweight one-stage training pipeline, SPLADE-Code achieves state-of-the-art performance among retrievers under 1B parameters (75.4 on MTEB Code) and competitive results at larger scales (79.0 with 8B). We show that learned expansion tokens are critical to bridge lexical and semantic matching, and provide a latency analysis showing that LSR enables sub-millisecond retrieval on a 1M-passage collection with little effectiveness loss. **Bio**: Simon is a third year PhD student at the University of Amsterdam, working on Information Retrieval and LLMs. He has graduated from a computer science engineering school in France, made an Erasmus exchange in London, during his master, at the imperial college london, and worked in the industry for 2 years at naver labs europe. Now he will present his latest work from an internship at naver labs europe. **Speaker #2:** Chuan Meng from University of Edinburgh **Title**: Revisiting Text Ranking in Deep Research **Abstract**: Deep research has emerged as an important task that aims to address hard queries through extensive open-web exploration. To tackle it, most prior work equips large language model (LLM)-based agents with opaque web search APIs, enabling agents to iteratively issue search queries, retrieve external evidence, and reason over it. Despite search's essential role in deep research, black-box web search APIs hinder systematic analysis of search components, leaving the behaviour of established text ranking methods in deep research largely unexplored. In this talk, we revisit key findings and best practices for text ranking methods in the deep research setting. In particular, we examine their effectiveness from three perspectives: (i) retrieval units (documents vs. passages), (ii) pipeline configurations (different retrievers, re-rankers, and re-ranking depths), and (iii) query characteristics (the mismatch between agent-issued queries and the training queries of text rankers). We perform experiments on BrowseComp-Plus, a recent deep research dataset with a fixed document corpus, evaluating a broad spectrum of text ranking methods across diverse setups. We find that agent-issued queries typically follow web-search-style syntax (e.g., quoted exact matches), favouring lexical, learned sparse, and multi-vector retrievers. Passage-level units are more efficient under limited context windows, and avoid the difficulties of document length normalisation in lexical retrieval. Re-ranking consistently improves performance, with deeper re-ranking depths amplifying gains. Translating agent-issued queries into natural-language questions significantly bridges the query mismatch and improves effectiveness. Related paper: [https://arxiv.org/pdf/2602.21456](https://arxiv.org/pdf/2602.21456) **Bio**: Chuan Meng is a postdoc at the University of Edinburgh, working with Dr. Jeff Dalton. He received his PhD from the University of Amsterdam in June 2025, supervised by Prof. Maarten de Rijke and Dr. Mohammad Aliannejadi. He was formerly an Applied Scientist Intern at Amazon. His research focuses on agentic information retrieval (IR) and deep research. He has published 25+ papers in top-tier venues such as SIGIR, ACL, EMNLP, NAACL, CIKM, AAAI, ECIR, and TOIS, with 650+ citations on Google Scholar and an h-index of 16. He has co-organised tutorials and workshops at SIGIR 2025, WSDM 2025, ECIR 2024–2026, SIGIR-AP 2024. **Counter:** SEA Talks #303 and #304.

**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.

**The idea for this group is to build a community where men can gather together and build connections & learn and grow from each other.** How we start each meeting is by each of us checking in with our "roses and thorns" aka what are the good things and the bad things going on in your life recently? Then we will go into a topic discussion. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **COMMUNITY AGREEMENTS** \*\*THERE WILL BE A ZERO TOLERANCE POLICY FOR NO-SHOWS. IF YOU RSVP TO A MEETING AND FAIL TO SHOW UP WITHOUT NOTICE, YOU'LL BE REMOVED FROM THE GROUP. THIS IS TO PRESERVE THE INTEGRITY OF THE GROUP\*\* 1. Confidentiality - EVERYTHING that is shared NEVER leaves this space so that this space remains safe and sacred. There is a zero tolerance policy for this. If a man is in violation of this, they will be permanently removed from the group. 2. Non-Judgement - we respect and honor every man’s truth so that we may receive the same from others. While we may not agree on everything, we commit to respecting every man’s perspectives and engaging in honorable discussion with one another. 3. Be committed - honor your commitment to this group and to yourself. If you attend a meeting, please commit yourself fully to the meeting. Also be committed to your own journey. When we fail, we own it & clean it up. 4. Speak from the heart - this is NOT a space to “look good”, have the “right” answers, and have it all together. Relax and know you are not alone. Be exactly who you are within the safety of this space. 5. Be supportive - This means always willing to provide encouragement to your fellow men, encourage action and momentum in each other’s lives.. Be willing to challenge each other. Be willing to hold each other accountable. 6. Participation - what you receive from this community will be a reflection of what you put into it. Period. We ask that you share your perspectives, reflect on others, and give/receive support when and where it’s needed.
