It's time for something new: after three years as a network architect at Logius, I'm going back into business for myself.
I'm going to focus on providing advice about connectivity to the internet to organizations for which an internet connection is a critical asset.
Watch this space for more information!

Het is tijd voor een nieuwe uitdaging: na drie jaar als netwerkarchitect bij Logius begin ik vanaf 1 maart weer voor mezelf.
Hierbij richt ik me op het adviseren over connectiviteit naar het internet aan organisaties waarvoor een internetverbinding een kritisch bedrijfsmiddel is.
Hou deze plek in de gaten voor meer informatie!

Last year Apple introduced dark mode in MacOS. This is really nice at night because your eyeballs aren't blasted with tons of white backgrounds in pretty much all windows. Unfortunately, most web pages still use a white background. Obviously you can redesign your website to conform to dark mode, but this looks rather stark on computers in light mode.
The solution would be to have your website render dark on a system in dark mode and light on a system in light mode. As of the new version of Safari included in MacOS 10.14.4 Mojave that was released just now, you can actually do that, as you can see here. Just switch your system between light and dark mode and you'll see this webpage switch over accordingly.
I like to use this terminal command to switch between light and dark mode:
sleep 2; osascript -e 'tell application "System Events" to tell appearance preferences to set dark mode to not dark mode'
(Change the last "not dark mode" to "true" or "false" to enable or disable dark mode. The line above toggles back and forth.)
On your website you need to set up conditional CSS with media queries. This is what I use:
<style type="text/css" media="screen, print">
body { background-color: #f0f0f0; }
A { color: #c00000; text-decoration: underline; }
A:visited { color: #700000; text-decoration: underline; }
H1 { font-family: futura, arial, sans-serif; font-size: 14pt; }
</style>
<style type="text/css" media="screen and (prefers-color-scheme: dark)">
body { background-color: #202020; color: #d0d0d0; }
A { color: #ff6734; }
A:visited { color: #d82000; }
</style>
The first part between sets everything up for light mode, with a very light gray background.
Then the second style section (in bold) with (prefers-color-scheme: dark) overrides those earlier color settings. Note that all the font settings from the first style section are inherited by the second style section; no need to restate all of those.
That's it! Pretty cool, right?
Update: have a look here for more information, including how to use dark mode with javascript.

Morgen zijn de verkiezingen voor de Nederlandse afgevaardigden naar het Europees Parlement. Ik had half-en-half het plan om hier een stukje te schrijven over wat nu de relatie is tussen de Nederlandse partijen en de Europese fracties waar zij deel van uitmaken. Maar: Stuk Rood Vlees heeft dit veel beter gedaan dan ik kon!
Absolute aanrader om deze blogpost te lezen.
De echte uitslagen komen pas zondagavond om 23 u nadat de stembussen de alle overige landen ook gesloten zijn, maar naar verwachting zal er donderdagavond wel een exitpoll zijn en wat uitslagen van individuele stembureaus.
Ik ben ook erg benieuwd naar de Britse uitslagen en de consequenties die met name de Tories hieraan zullen verbinden voor de brexit.

Interessant: de NRC schrijft over BGP en route leaks. Ben benieuwd of dit elders opgepikt gaat worden.

Although it says "4K TV", as far as I know, there's (virtually) no actual TV broadcast in 4K, so what I'm really talking about here is the state of home theater technology as of around 2018. This post is about the hardware and the formats. Part 2 will be about 4K content and whether the 4K thing is worth the money.

So with all the technical details out of the way in part 1, let's have a look at where to get 4K content and whether it's worth the trouble and the expense. Where I've found 4K content...

In de NRC van dinsdag 1 oktober 2019: "Noodscenario's bij snelle zeestijging" en daarboven een foto van trekkers/tractors op het strand van Scheveningen voor het Kurhaus. Maar dat blijkt toeval te zijn, zie het smalle kolommetje rechts van de foto.

It's insane. I already spent nearly 800 euros on bluetooth headphones this year. And then Apple released the Airpods Pro, costing € 279 here in the Netherlands. And I couldn't help myself and bought a pair. So let's see how they compare...

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.

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.
