Writing Fractions In HTML
I have been thinking about digitising my notes of mathematics and physics exercises done over the years and one option would be to add them to my blog. As I don’t have a business subscription I cannot use a math editor. One option available to me is to use LATEX but for some of the…

Swift Playgrounds
A year ago, at the beginning of the first lockdown we started with Swift playgrounds at home on the iPad to teach our 10 year old son Merijn a bit of coding. I had looked at it earlier but then it wasn’t available yet in Dutch. Last year it was and with a lot of…

Personal Web Page Developments
Near the end of the previous millennium my internet provider brought ADSL connections to the market and I subscribed to the service. No more dial in connections with a modem over the phone line.

Response Status 418
If you wonder where Response 418 is coming from, this is a ‘fake’ http status code from 1998 that was invented as an April fools day joke. The response is part of the ‘hoax’ Hyper Text Coffee Pot Control Protocol or htcpcp versus the real Hyper Text Transfer Protocol that you use daily surfing the…
