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.

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.

'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.

In subsequent classes we will verify and hone our talents with activities and discussion. These are hands-on workshops and participation is expected. The goal of our series will be to develop expertise in areas of particular interest such as mediumship, channeling, divination, healing and, etc.. Our ultimate directions will be determined by class members as we evolve. I look forward to sharing and discovering with you. - Cynthia
