I work seasonal jobs in Europe and spend the winters in Southeast Asia, so my money lives in a Dutch current account, a savings account, a credit card, a multi-currency app, an online wallet, a money-transfer service and, most of the time, a wallet full of local cash. No budgeting app handles that well. Banks…
Waarom fondsen campings kopen die als camping bijna niets verdienen Hetzelfde stuk grond met dezelfde huisjes is voor de ene koper negen miljoen waard en voor de andere veertig. Dat verschil verklaart wat er met Nederlandse campings gebeurt. Jaarplaatsen verdwijnen, er komen chalets voor terug, en de nieuwe eigenaar heet Blackstone, PAI of het staatsfonds…
Every summer at Fabulous Village, the same question gets asked at reception a hundred times a day: “Which way to pitch 1104?” The official site plan is a lovely piece of graphic design, but it’s not a map you can search. So I built one — a small web app where you type in a…
Nederlands hieronder – Italiano sotto Driving from Rome towards Ostia, you see it on both sides of the Cristoforo Colombo: grey crowns, bare branches, trees that have not looked well for some time but are still standing. The stone pines that have shaped Rome’s skyline for centuries are sick. Not everywhere, but in enough places…
Instagram has a “Collections” feature — you can save reels and posts into named folders. Handy for yourself. Useless for anyone else, because there’s no way to share a collection with another person.

Het KNMI berekent het landelijke neerslagtekort uit dertien stations. Op X kreeg ik te horen dat dat er veel te weinig zijn. Dus heb ik het uitgerekend.

Improving Cleaning Quality Through Statistical Sampling and Performance Incentives It is hard to get a consistently high cleaning standard from an external company. The usual problem isn’t the people or the mops — it’s the incentive structure. Do well for months running, and nothing in particular happens: no recognition, no reward. Do badly, and often…
Hoewel de thermometer in alle gevallen 29 graden aangeeft, voelt de hitte tijdens het hardlopen in Da Nang anders dan gedurende acroyoga in Chiang Mai — en weer anders dan als je een biertje op een Amsterdams terras drinkt.
Vervolg op Sterfte vs temperatuur (november 2023) naar aanleiding van enkele vragen op X.com Samenvatting In het eerdere artikel werd op basis van KNMI- en Eurostat-data een V-vormige relatie tussen gemiddelde weektemperatuur en sterfte in Nederland gevonden, met een optimum rond 16,5 °C.

I had a folder with thousands of PDFs. Invoices next to yoga manuals next to scanned maps next to bank statements. Filenames like xkbf2291.pdf and 00183774.pdf. No structure whatsoever.

Over the years, a rhythm formed in my life. Summers find me working seasonal jobs on campings in Europe, while winters pull me back to Asia. Different places, different cultures, yet always the same thread running through it all: people, movement, and the spaces we create together. I would not call myself a hardcore acroyogi….
Some people point to classes and workshops as the missing link. They help Level 1 and 2 progress faster. At the same time, many Level 4 and 5 have invested a lot of time, energy, and money in training, so they prefer not to offer the same guidance for free at every jam. Other critical…

I work at a campsite and I often enjoy the sunset. But it moves through time. so I was wondering, “Where exactly does the sun go down?”. If you follow my blog, you know that I didn’t just want to know. I wanted to see it, understand it, and visualize it. So I pulled out…
As a hospitality and leisure professional, I hate handwritten notes. So the first thing I do when I work in a new place is make a door sign like “We’ll be back in a minute.” But what if your colleague from another campsite sees it and wants one too? And then their colleague? I’m too…

Summary This study examines the relationship between mortality rates, wastewater virus measurements, and COVID-19 vaccination levels during the pandemic. Using open data from CBS, Eurostat, and vaccination records, the analysis applies multiple linear regression, VIF tests, and interactive visualizations in Python. The results show a strong positive correlation between virus concentrations in wastewater and mortality,…

Abstract This study presents a novel approach to analyzing excess mortality during the COVID-19 pandemic using quadratic curve fitting. By comparing linear and quadratic models applied to pre-pandemic mortality data, we demonstrate that quadratic fitting results in lower estimates of excess mortality for the years 2020 and beyond. This finding suggests that previous linear extrapolations…
