No More Mr Nice Guy

Mark your calendars: the next Haskell Utrecht Meetup will be on June 1st! This time, we will be generously hosted by Chordify's in their office, Burgemeester Reigerstraat 89. We hope to see you there! Agenda: * 19:00 Doors open * 19:30 Welcome * 19:35 Hugo Peters - Making people secretly use an Haskell EDSL * Break * 20:30 Matteo Bertorotta - Compilation techniques using Fusion in Haskell * 21:00-ish Wrap up **Hugo Peters (NVIDIA) - Making people secretly use an Haskell EDSL** In this talk, I'll show how we use the bluefin effect system to design simple but effective DSL builders for non-Haskell programmers. **Matteo Bertorotta (Utrecht University) - Compilation techniques using Fusion in Haskell** We discuss fusion as a powerful mechanic for optimization during compilation, specifically focusing on how fusion techniques eliminate intermediate data structures to maximize runtime efficiency. We explore two similar examples in vastly different domains: (1) Transforming elegant library code into a performant counterpart, and (2) fusing complex gradient computations in reverse automatic differentiation into a single pass.

Tijdens de maakavonden van Meet Je Stad soldeer je je eigen meetkastje dat temperatuur, luchtvochtigheid en fijnstof\* kan meten. Het solderen is geschikt voor iedereen: van beginner tot expert! Daarnaast bieden we begeleiding, dus hoef je niet bang te zijn dat je er niet uit komt. Ter deelname betaal je €15 voor de materialen. Vaak lukt het niet om al het soldeerwerk binnen één avond af te krijgen, maar dit is geen probleem; tijdens onze volgende maakavonden kun je langskomen om je werk af te maken. Inmiddels zijn er in de stad Utrecht nu zo’n 150 mensen die hun eigen meetkastje hebben gesoldeerd. Als je kastje af is wordt hij geregistreerd en kun je hem bij jou thuis ophangen/neerzetten. Hierbij krijg je instructies zodat je de juiste locatie kunt kiezen en je metingen zo betrouwbaar mogelijk zijn. Als het dan eenmaal hangt kun je via de kaart op de [website van Meet Je Stad](https://meetjestad.net/index3.php?loc=Tb) bijhouden welke metingen je kastje neemt: zo kun je bijvoorbeeld zien op welke momenten het bij jou het warmst is en vergelijkingen maken met waardes van andere meetkastjes. Dat kan door middel van [deze tool](https://mjs-datavisualisation-fez7kynngq-ez.a.run.app/) die je helpt om grafieken te maken. Dan kan je er achter komen hoe jouw omgeving ervoor staat in vergelijking met de rest van de stad. Meet Je Stad organiseert ook kennisavonden met gastsprekers die vertellen over hitte, fijnstof en andere burgerinitiatieven in de stad. Dit zijn ook gelijk geschikte momenten voor deelnemers om met elkaar in discussie te gaan over hun metingen en ondervindingen. Zo hopen we een netwerk van betrokken inwoners te creëren en meer te weten te komen over de milieuomstandigheden in de stad! *\*De fijnstofsensor is optioneel en kost 20 euro extra. Indien je deze bij je meetkastje wilt moet je deze via een draad met een stroombron binnen 15 meter kunnen verbinden.* **Organisatie:** Milieucentrum Utrecht (MCU) in samenwerking met de Makerscommunity HaHaHo. **Locatie:** Bibliotheek Neude, Huis van Actief Burgerschap (begane grond) **Kosten:** 15 euro voor materiaalkosten, 20 euro extra voor fijnstofsensor. (Meet-up suggereert bij het aanmaken van een account dat een betaald abonnement vereist is. Dit is niet zo, op de pagina waar gevraagd wordt om een abonnement te kiezen staat rechts bovenin de optie "Ga door met het gratis plan".) *Bij te weinig aanmeldingen kan de workshop afgelast worden.*

ATTEND IN PERSON OR ON ZOOM **NB This event will now take place at the Café of [St. Hilda's East Community Centre](https://www.google.com/maps/@51.5244243,-0.0746385,17z?entry=ttu&g_ep=EgoyMDI0MDkwNC4wIKXMDSoASAFQAw%3D%3D), 18 Club Row, London E2 7EY.

Heraclitus states that “thinking is common to all”. However, this seemingly optimistic statement is soon qualified by his lament that people don’t understand, and therefore don’t recognise the importance of, his own philosophical message: they clearly don’t think well enough. The lights are on but no-one’s home, he seems to say. But is he really disappointed at the poor quality of common thought or because others don’t think like him? So, yes, we all think, but what is it that is really shared? What is common about common sense, if it exists at all? In my talk at Kant’s Cave I would like to explore with you the possible meanings, uses and value of the idea of “common sense”. We will discuss thinkers from Kant and Voltaire to Gadamer and Hannah Arendt.

**Praat mee over de toekomst van Defensie en Lelystad Airport in Flevoland** Tweede Kamerlid Laurens Dassen en luitenant-generaal b.d. Kees Matthijssen gaan in gesprek met inwoners uit Flevoland. Meer info: https://voltnederland.org/flevoland/agenda/de-toekomst-van-defensie-in-flevoland **Op maandagavond 1 juni** organiseert Volt Flevoland een openbaar evenement in congrescentrum De Pijler in Lelystad. We gaan dieper in op de toekomst van Defensie in onze provincie, met aandacht voor de mogelijke komst van een superkazerne en de rol van Lelystad Airport. **Bijzondere gastsprekers** zijn Tweede Kamerlid **Laurens Dassen** die vanuit Volt kijkt naar bredere maatschappelijke en Europese keuzes, en **luitenant-generaal b.d. Kees Matthijssen**, die vanuit militair perspectief duiding geeft aan ontwikkelingen in de wereld, Europa en Nederland, en in die context ingaat op de betekenis van een kazerne in de polder en het gebruik van Lelystad Airport voor de F-35. **Wat betekent dit voor Flevoland?** De plannen voor een grote kazerne en de komst van F-35’s hebben grote gevolgen voor onze veiligheid, ons werk, innovatie, de natuur, onze leefomgeving en de woningmarkt. Vaak kiezen partijen voor een beperkte blik en kortetermijnoplossingen. Volt Flevoland kijkt verder en wil dat de inwoners van Flevoland zelf meepraten over deze keuzes. **Veiligheid stopt niet bij grenzen;** daarom kiest Volt voor een sterke Europese krijgsmacht. We nemen onze regionale verantwoordelijkheid serieus en zien de kansen van een kazerne, maar beschermen tegelijkertijd onze natuur en leefbaarheid. Echte vooruitgang is een balans tussen internationale veiligheid en lokale leefbaarheid. Ook rond Lelystad Airport wil Volt een toekomst met duurzame keuzes: het vliegveld blijft wat ons betreft gesloten voor vakantievluchten. We stimuleren minder korte vervuilende vluchten (tot 650 kilometer) en werken liever samen met België, Frankrijk en Duitsland aan betrouwbare en snellere treinverbindingen als duurzaam alternatief. Deze plannen zijn complex en hebben veel gevolgen voor de polder. Daarom gaan we hierover graag met de bewoners in gesprek. De avond biedt ruimte voor vragen, een open dialoog en kennismaking met andere betrokken inwoners. Iedereen is van harte welkom en de toegang is gratis.

If you are living in The Netherlands, by now, you may well have noticed the amount of open water. If you enjoy cycling in the city, you may wish to feel safer as you navigate the bridges and canals. And you may also want to get ready for visiting the beach, pools or the many lakes this summer. Learning how to swim takes approx 1 year and it all starts with the very first lesson. New comers enroll via our website and pay € 30,50, this is the first lesson and a goody bag. After the class you agree with the personal swim coach how to continue to obtain your final objectives. Enrolling is only possible via [www.your-personal-swim-coach.nl ](https://www.your-personal-swim-coach.nl/)hence a rvsp via meetup is not enough.

Samen sporten, gewoon voor de fun, elke week een divers programma, met allerlei verschillende sporten. Je hoeft niet de beste te zijn, maar wel zin hebben om samen te spelen en te leren. Tijdens een training doen we verschillende spelletjes, basketbal, voetbal. volleybal, spikebal, honkbal. Kom je ook, de bal ligt bij jou!! Eerste keer meedoen is altijd gratis, daarna kan je beslissen of dit voor jou is, of niet!! Dus kom een keer proberen. Kan je niet op deze dag, we sporten ook op andere dagen nl Zondag om 9:30 of Maandag om 20:30 Stuur mij een berichtje als je op die dagen een keer wil proberen! The amount of people rsvp'd to this game doesn't match the real number of people at the event, as Meetup is only used for promotion purposes.

Do you love books, or have you been wanting to get into reading more? Then this might just be the event for you! At this book swap everyone brings one or a few books they no longer need. We put them all out on the table and from there it's up to you, see if something catches your eye and take home whatever you'd like to read next. Any language is welcome, so bring whatever is sitting on your shelf! At the end of the meetup you can take back the books you brought that weren't picked up, or leave them with the organiser who will donate them to a local secondhand shop. This event is organised on a weekday evening as a nice little break in the middle of the week to meet fellow book lovers over a good drink. ⚠️ If you're unsure whether you can make it, please free up your spot for someone else.

Join us every first Friday of the month to hang out and have a drink. Start off the weekend in a fun way :) Meet familiar faces or some new people, especially if you're new in town. February is cold, but no worries, we'll be inside. 🙂 Join us in En Public, a spacious bar/restaurant in Griftpark (near the canal bridge), at the former location of Peter's Bistro. If you can't make it on Friday, try joining Mingle Mania Tuesday drinks.

With that in mind, please note that it is nice to support the venue by ordering a drink. We greatly appreciate if you settle your bills at latest by the end of the evening.

\# 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**: Treat Her Like a Lady **Language**: Dutch **Subtitles**: English **Length**: 110 min **Director**: Paloma Aguilera Valdebenito **More info**: https://www.focusarnhem.nl/agenda/english-subs-treat-her-like-a-lady/ **Ticket link**: https://www.focusarnhem.nl/tickets/144301/ **Synopsis:** When single mother Sandra (radiant performance from Nienke Plas) is evicted from her apartment due to fraud, she convinces her daughters that their emergency shelter is a holiday hotel. Sandra is just about keeping it together. Living with her two daughters and partner in a modest but colourful Amsterdam apartment, she makes ends (mostly) meet through cleaning jobs and welfare payments. But when she’s faced with a rapidly mounting series of hurdles – unpaid bills, an accusation of fraud, the revelation that her partner has been cheating – Sandra must draw upon all her determination and creativity to keep her daughters out of social care. An effervescent second feature from Dutch filmmaker and writer Paloma Aguilera Valdebenito (Out of Love, IFFR 2016), this jewel of a film offers poignant criticism of a broken social system with all the vibrancy and optimism of a musical. Nienke Plas is masterful in her central performance as the matriarch, whose fortitude, boldness and charisma bring to mind the best of Almodóvar’s heroines. Featuring a gorgeously saturated colour palette and a fabulous needle-drop soundtrack, Treat Her Like a Lady demonstrates how warmth and resilience can transform the most desperate situations into fresh opportunities for laughter and light. **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!

'HOMEGOING' by Yaa Gyasi 'Two sisters with two very different destinies. One sold into slavery; one a slave trader's wife. The consequences of their fate reverberate through the generations that follow. Taking us from the Gold Coast of Africa to the cotton-picking plantations of Mississippi; from the missionary schools of Ghana to the dive bars of Harlem, spanning three continents and seven generations, Yaa Gyasi has written a miraculous novel - the intimate, gripping story of a brilliantly vivid cast of characters and through their lives the very story of America itself. Epic in its canvas and intimate in its portraits, Homegoing is a searing and profound debut from a masterly new writer.' ***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. Please cancel your attendance in advance if you are unable to join, so that those on the waitlist can participate. Looking forward to seeing you all IN REAL LIFE then! Best regards, Sandra

On a list of "My Favorite Things", few people would put a "break up" in their top ten. More often, these words evoke feelings of shame, embarrassment, poor choices, and bad or sad endings. Before the new and beautiful can be built, the old, broken, and unnecessary must be cleared away. This process can be painful, but it is good, needful, and can produce wonderful results when done wisely and well. How does one break free from anxiety, comparison, or shame? Christian Bevere points people to the freedom God desires for His children, as well as giving practical ideas on how to shed both unhealthy baggage and the lies that seek to leave us anchored to past failure. Drawing from the Bible, ***Break Up With What Broke You*** clearly shows that what Satan would seek to use for evil, God uses for good and to accomplish His purposes. Join us **Tuesday, June 2, 2026, at 6:30 pm**, when we gather at **True Food Kitchen, Easton Town Center, Columbus**. We'd love to see you there! Get your tickets on [EventBrite](https://www.eventbrite.com/e/break-up-with-what-broke-you-columbus-ohio-tickets-1987018079565)!

**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.

Join us as we get together to see Paul Rudd in the latest comedy-drama-musical from John Carney, POWER BALLAD! The film follows a washed-up wedding singer, a fading boy band singer and a stolen hit song. Here’s a description, trailer and plan for this event: DESCRIPTION: Rick, a washed-up wedding singer, and Danny, a fading boy band star, bond over music and a late-night jam session. When Danny turns Rick's song into a hit, Rick sets out to reclaim the recognition he believes he deserves. Power Ballad is written/directed by John Carney, the master of the modern musical and creative mind behind Once, Begin Again and Sing Street! It stars Paul Rudd, Nick Jonas, Peter McDonald, Marcella Plunkett, Havana Rose Liu and Jack Reynor. BUZZ & ACCLAIM: The film premiered to rave reviews at this year’s Dublin International Film Festival where critics call it “a sure-fired crowd-pleaser” that “just might be the feel-good hit of the year!” Others say, “Paul Rudd delivers a career-best performance in this charmer” that’s both “hilarious and deeply moving." The film continues John Carney’s “long run of success with yet another charmer” and “a sharp, hopeful crowd-pleaser that strikes the right notes!” SUMMER OF ICE CREAM, VOL 2: SHAKE NO. 8!

Join us for Sharp Objects by Gillian Flynn! Fresh from a brief stay at a psych hospital, reporter Camille Preaker faces a troubling assignment: she must return to her tiny hometown to cover the unsolved murder of a preteen girl and the disappearance of another. For years, Camille has hardly spoken to her neurotic, hypochondriac mother or to the half-sister she barely knows: a beautiful thirteen-year-old with an eerie grip on the town. Now, installed in her old bedroom in her family's Victorian mansion, Camille finds herself identifying with the young victims—a bit too strongly. Dogged by her own demons, she must unravel the psychological puzzle of her own past if she wants to get the story-and survive this homecoming.
