Hash House Harriers

De *veertigste* monthly meetup van [Nimma.codes](https://www.nimma.codes/) alweer! We zijn een cross-language user group voor software developers in de regio Arnhem-Nijmegen en komen elke laatste dinsdag van de maand samen om te praten over alles wat met software development te maken heeft. Wees welkom! (ook als je niet programmeert) *Ditmaal zijn we wederom te gast bij Deftpower [Clean Tech Park Arnhem](https://cleantechparkarnhem.nl/).* **Programma** * **17:30 – 18:00** Inloop + food & drinks * **18:00 – 18:45** Talk 1: [Tim Steenvoorden](https://github.com/timjs) \- De lambda calculus in moderne programmeertalen * **18:45– 19:00** Pauze * **19:00 – 19:45** Talk 2: [Deftpower](https://www.deftpower.com/) - [William van der Vegt](https://vegt.dev/) \- Van thuislaadpaal naar actor: kennismaken met schaalbaar sessiebeheer in \.NET Orleans * **20:00 - 21:00** Netwerken **Talk 1: Tim Steenvoorden (Open Universiteit en Radboud Universiteit) - De lambda calculus in moderne programmeertalen** Eén herschrijfregel, geen types, geen geheugen, geen loops. In 1936 definieerde Alonzo Church een rekenmodel van bijna irritante eenvoud die toch even krachtig is als een Turingmachine: de lambda calculus. Deze sessie is een reis van die wiskundige kern naar de code die je dagelijks schrijft. We beginnen met pen en papier: lambda termen lezen, schrijven en reduceren. We gebruiken niets anders dan functies voor het bouwen van datastructuren. Vervolgens maken we de vertaalslag naar closures, higher-order functions, immutability en pipelines in talen als Java(Script), Python, Kotlin, Haskell en Rust. Het doel is niet om morgen anders te programmeren. Het doel is om te begrijpen waarom moderne talen de afgelopen decennia steeds meer functionele concepten hebben overgenomen en wat de gemeenschappelijke wortel daarvan is. **Talk 2: Deftpower - William van der Vegt - Van thuislaadpaal naar actor: kennismaken met schaalbaar sessiebeheer in .NET Orleans** Ik ben van kleins af aan een echte techfanaat; thuis hobby ik met gadgets, servers en frameworks. Sinds een klein half jaar werk ik bij Deftpower, waar bedrijf, sector én techstack perfect bij me passen. Daarvoor vijf jaar bij Info Support, vooral voor de klanten Air Miles en Moba. Vanuit die liefde voor tech vertel ik wat over .NET Orleans: het framework waarmee we bij Deftpower duizenden thuislaadpalen tegelijk beheren. Duizenden live, stateful verbindingen, elk met hun eigen sessie en toestand. In klassiek .NET loop je dan al snel tegen locks en race conditions aan. In deze talk laat ik zien hoe we elke laadpaal als een actor modelleren met .NET Orleans, en zo schaalbaar bouwen zonder grote concurrency issues. Inclusief een praktische kennismaking met het actor-model, voorkennis van Orleans is niet nodig. **Locatie** [Clean Tech Park Arnhem - Connector gebouw KB - 1ste verdieping.](https://maps.app.goo.gl/VcFWRSbF5fT6J2PB7)

**Welcome to our June UX Beers in Antwerp!** This time, we will host our event on Tuesday the 30th of June at Craftzing in Antwerp. [Ariad](https://www.ariadgroup.com/) and [Creative Skills](https://www.creativeskills.be/) sponsor our events. Follow the event online? We stream live via [Youtube](https://www.youtube.com/watch?v=EBqyTDAyQBw) \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- \#\#\# UX TALKS **Talk 1:** **UX with AI: Did we all just get promoted?** By An-Sofie Rombouts, Product designer @ Gorilla Working in a startup often means designing without established UX processes. So with AI emerging, it can feel like a lifeline: faster prototyping, '*deeper*' research, and more concepts to explore. But somewhere between the third AI-generated prototype and losing the thread of your prompted designs, it can become painfully obvious what the impact is of designing with LLMs. We're not executing anymore, we're reviewing, approving, and critiquing, like a manager. This talk gets honest about what that actually means: the speed gains are real, but the cognitive debt is quietly compounding, and your future as a designer depends on understanding why. Explore how designers can protect their cognitive depth, enhance their review capacity, and stay in control when the machine can almost draw anything. **Talk 2:** **Growing UX in organisations that are not there yet.** By Koen Peters, Designer at Namahn More and more organisations are asking us to help build design expertise in-house, even putting together a design team for them. I have learnt that in such cases, you need to set aside your own biases and assumptions first: your neatly mapped-out methodology, your Figma dogmas and all the other things you as a design agency take for granted. The reality in these organisations is often very different: limited resources, no design culture and few or no trained designers on the team. Through a few client case studies, I will show how we have tackled such challenges. Organising a training in UX and design thinking is a good first step, offering a chance to get to know the team and identify which skills are already there and which are missing. I will also demonstrate tools and activities that we have used to help a team get started and become more aware of UX research and design. These include a script for choosing the right UX approach, skills assessment models to identify gaps and first steps towards creating a design playbook. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- \#\#\# SCHEDULE 18:00 - Doors open.

Look for these types of events: UX Beers Periodically, we gather at a different agency or venue to drink beers, network and listen to speakers on various themes in the world of UX and digital design. UX Antwerp: Each last Tuesday of the month UX Brussels: Each second Tuesday of the month, 4x per year UX Workshops Now and then we organize events to dive deeper into specific skills and techniques in UX. These are smaller, hands-on workshops designed to boost your UX toolbox. \*\*\* The UX Belgium Meetup Team

We’ve all had it: going blank mid-sentence, a tight chest before a hard conversation, or that strange emptiness right after finally getting what we wanted. This first gathering is a chance to slow down and actually listen to what your body’s been holding. For this session, we’ll explore the question together: what is your body trying to tell you? Through a short opening round, gentle orientation, and guided somatic practice, you’ll get a real feel for what Somatic Circle is about — not theory, but actual practice. What to expect: 🗣️ A short opening round — a few words on how you’re arriving 🧭 A brief framing of the theme 🌀 Guided somatic practice — breath, presence, and gentle inquiry 💬 Space to reflect and share, if you want to It is a free event!

Every Tuesday, the group 024 Waalrunners go for a run at a distance of between 7km - 10km depending on the group. Everyone is welcome to join, you just need to turn up at 20:00 on Tuesday in front of Brouwerij De Hemel. There are different routes every time, and the group welcome all new people to join them.

'THE SYMPATHIZER' by Viet Thanh Nguyen 'The winner of the 2016 Pulitzer Prize for Fiction, as well as seven other awards, The Sympathizer is the breakthrough novel of the year. With the pace and suspense of a thriller and prose that has been compared to Graham Greene and Saul Bellow, The Sympathizer is a sweeping epic of love and betrayal. The narrator, a communist double agent, is a man of two minds, a half-French, half-Vietnamese army captain who arranges to come to America after the Fall of Saigon, and while building a new life with other Vietnamese refugees in Los Angeles is secretly reporting back to his communist superiors in Vietnam. The Sympathizer is a blistering exploration of identity and America, a gripping espionage novel, and a powerful story of love and friendship.' ***Please read the book and join us for a lively discussion (in English) about the contents during our afternoon book club meeting.*** \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **PLEASE NOTE:** This is an IN-PERSON event in Amersfoort, The Netherlands.
