Hi, I'm Iljitsch van Beijnum. This is the main page of the site.

Fun with fonts!

After many years of using Century Gothic and its clone URW Gothic Book for my website muada.com, I felt it was time to reconsider that choice. So I went font hunting!

Over the course of my hunting expedition, found a nice new font, Muli, and I created a page that lets you compare different fonts and their weights interactively. Have a look.

Time to turn off IPv4 (just a little)

Another month, and we'll be living in the 2020s. And yet, 70% of the internet is still IPv4-only. (I'll be writing a story looking back on IPv6 progress the past decade in January.) So I thought: maybe I should draw a line in the sand and turn off IPv4 for my website. But then how will those 70% find me, and all the links to older content will be dead to much of the internet. Click below to continue reading.

Note: this is an example of the warning image, your IPv6 connectivity may be fine!

Tijd om IPv4 uit te zetten (een beetje)

Over een maand leven we in de jaren '20 van de 21e eeuw. En toch heeft 70% van het internet nog steeds alleen maar IPv4. (In januari schrijf ik een verhaal dat terugkijkt naar de voortgang van IPv6 in het afgelopen decennium.) Dus ik dacht: misschien moet ik een streep trekken en IPv4 uitschakelen voor mijn website. Maar dan kan 70% me niet meer vinden, en de links naar oudere artikelen zijn dan dood voor een groot deel van het internet. (Klik beneden om verder te lezen.)

Let op: dit is een voorbeeld van de waarschuwing, je IPv6-connectiviteit kan prima in orde zijn.

→ America is not the land of the free but one of monopolies so predatory they imperil the nation

Excellent piece by Observer/Guardian columnist Will Hutton based on the work of economist Thomas Philippon:

The news is that over the last 20 years per capita EU incomes have grown by 25% while the US’s have grown 21%

And:

The US economy is becoming increasingly harmed by ever less competition, with fewer and fewer companies dominating sector after sector – from airlines to mobile phones.

Because:

But why has this happened now? Philippon has a deadly answer. A US political campaign costs 50 times more than one in Europe in terms of money spent for every vote cast. [...] Corporations want a return on their money, and the payback is protection from any kind of regulation, investigation or anti-monopoly policy that might strike at their ever-growing market power.

A real eye-opener.
