Recently I've been playing The Farmer Was Replaced. There is something quite satisfying about seeing your algorithms come to life, especially as normally I'm too lazy to make a decent visualisation. In the open source philosophy, here's my final script: gist.github.com/Koenvh1/a8ca...

Alle updates van de podcasts in het Rijkspodcastregister staan op GitHub. Als bijvangst kan ik nu zien wanneer bijvoorbeeld een spelfout in een aflevering verbeterd is of dat een aflevering is toegevoegd of verwijderd. Misschien komt die dataset nog een keer van pas :-) github.com/koenvh1/rijk...

My Stream Deck plugin "ScreenDeck" (to use my Stream Deck as video player) is now available on GitHub! github.com/Koenvh1/Scre...

The roadbooks I made for Dakar 18 and Dakar Desert Rally now end up on the first page if you Google "Dakar roadbook". As a consequence people have been emailing me thinking they are the roadbooks for the real 2020/2021/2022 Dakar seasons. Mission failed successfully I guess :-)

Some time ago I bought a Stream Deck (I also wrote a blog about it), but I could never actually stream anything to it. That had to change. Recently I've been working on a plugin to stream live video to the Stream Deck. It works remarkably well:

After 12 years of loyal service, my dashboard for Raceroom has stopped working. It was time for something new, which gave me something to tinker with again. I also just now caught up with all the added functionality from the last 12 years, like showing the current flag.

One last addition to my PC (which had to arrive from China): two LED spotlights. Both because I like the look, and because I can more easily see that my PC is still on — it's so quiet most of the time I sometimes forget it is still running.

Because some people requested it: I have now written a longer article about the why and how of building the custom HUD for Dakar Desert Rally on my blog. blog.koenvh.nl/building-a-c...

I have the uncanny ability to find really niche things to develop for. This weekend: a dashboard for Dakar Desert Rally. It only shows the speed, but that's all I need. Plus I learnt a thing or two about reverse engineering Unreal Engine and extracting values from running processes.

Last week a parcel by @alexfursuitmaker.bsky.social arrived and I'm chuffed to bits with it - world, say hello to Rakoen (pronounced as Raccoon).

I built a new pc after not changing anything for 8+ years. I decided to document my experience, which you can read here: blog.koenvh.nl/lets-finally...

13 jaar geleden publiceerde ik WIDM Exam. Hoewel ik al lang opgehouden ben met ontwikkelen daarvan, wordt het tot op de dag van vandaag nog steeds gebruikt - dat had ik van tevoren nooit verwacht.

De afgelopen weken ben ik bezig geweest met het opzetten van het Rijkspodcastregister. Aangezien het waarom, wat, en hoe te lang is om hier te plaatsen, heb ik het hier opgeschreven: blog.koenvh.nl/het-verhaal-...

Met hulp van vele anderen is het aantal podcasts in het Rijkspodcastregister (een overzicht van alle podcasts geproduceerd door of in opdracht van de Rijksoverheid) nu 141. Ongeveer 25% is exclusief op Spotify beschikbaar en niet via RSS. rijkspodcast.koenvh.nl

My love-hate relationship with backups continues, though this time it seems like I finally found something that ticks most of the boxes. tl;dr: it's restic with Backrest. Read the full version here: blog.koenvh.nl/the-tale-of-...

De Rijksoverheid produceert een tal van podcasts. Vele daarvan zijn helaas niet of nauwelijks vindbaar. Ik vond het tijd om daar verandering in te brengen, en ben begonnen met het maken van een Rijkspodcastregister. De eerste versie staat vandaag online: rijkspodcast.koenvh.nl

Sometimes the simplest programming projects bring the greatest joy, like this button on my Stream Deck that allows me to turn the fan behind my simracing setup on and off (using a smart plug). It's really nice, especially with summer around the corner.

As many people probably already know, I fly a rainbow flag outside my house. Not just during pride month, but pretty much year round. I hope that one day LGBTQ+ acceptance will be as self-evident as women's voting rights, but until that day there is still something to fight for.

Good morning!

Good morning! Last weekend I made a clock where it's always 11 AM, just the timezone changes, so I can always say good morning. See it for yourself here: koenvh.nl/playground/1...

After over two months we resume the cookie experiment at the University of Twente, this time using stroopwafels. Admittedly at this point I've stopped tracking the data.

Gisteren was er een ontbijtsessie "Wet Open Overheid", waar ook de transparantieprijs werd uitgereikt. Van de 4 nominaties was van 2 de strekking "probeert de wettelijke termijn te halen". Volgens mij is dit een teken dat er nog winst te behalen valt. ibestuur.nl/artikel/open...

Even though it is now over a month ago I was busy this April Fools. I made a summary of the things I did; if you're interested, you can read about it here: blog.koenvh.nl/april-fools-...

What do you get when you combine typesetting, printing, and automation? A car full of cardboard boxes. Read all about it in my post about how I made 252 rally pacenote booklets: blog.koenvh.nl/how-i-made-a...

Recently I had to look into backup solutions again, and because of that I decided to write about my backup journey and gripes with most backup software. You can read the full piece here: blog.koenvh.nl/a-tale-of-ba...

This weekend's project: PedalPal, an application that allows someone else to control your pedals in any racing game. I'm still tweaking with it, but it works very well so far.

Some people have asked me "why does the Phone Book of the Internet" not support IPv6? The simple reason is that it just does not fit:

As a small hobby project, I made booklets with the pacenotes for each stage in EA WRC. They are also available as PDF online if you want to print them yourself: koenvh.nl/wrc

The Phone Book of the Internet is now a physical book! 1.5 kg and 600 pages of popular domain names and their IP address listed in alphabetical order.

All good things must come to an end, and #SIGBOVIK 2025 is no exception. For those who missed my recorded presentation, you can watch it back on YouTube: youtu.be/_vgXi80y7Us

Whenever something doesn't work, it's generally the DNS. That's why we (re)introduce The Phone Book of The Internet. You can read more and download your own copy here: nlnetlabs.nl/news/2025/Ap...

My submission for this year's SIGBOVIK: Ad Fund 'Em - a LaTeX package that automatically inserts adverts in your manuscript so you can monetise the space. You only have to add `\usepackage{adfundem}`. You can find the full text here: github.com/Koenvh1/adfu...

I now printed the more permanent version of my illuminated logo - quite happy with how it turned out :-)

We continue our research into cookie acceptance among DACS members. Preliminary results show cookies are less likely to be accepted just after lunch.

Something I had planned on doing for a long time: an illuminated version of my logo. The regular paper draft version already looks pretty good - now let's turn it into a more permanent version.

My adventure with the UK Cabinet Office is now over. Most documents were not released, but from what was shared, we know that the Cabinet Office holds no information that forms the basis of the published call for input. Read the last part here: blog.koenvh.nl/the-end-of-m...

Preliminary research result: 9 out of 10 UT DACS members accept cookies provided they are chocolate chip. We are still looking into other varieties of analytical and tracking biscuits.

I managed to make something I wanted to have for many years: a Dutch rally co-driver voice for #EASportsWRC. Read the how and what here: blog.koenvh.nl/splitsing-dr...

After some small fixes you can now dial my DNS resolver: +31853695573 For more information see blog.koenvh.nl/dialns-a-dns...

This year's Christmas project: DialNS. Because sometimes you want to call your recursive DNS resolver. (It's not currently running, but I might hook it up to a more permanent number in the future) www.youtube.com/watch?v=szln...

The tracker from my car has been removed. It was both active and inactive at the same time. Read the full story here: blog.koenvh.nl/what-the-but...

The last couple of days I've been on a quest to find out what this switch does in my new car. Turns out I'm being tracked. You can read the full story here: blog.koenvh.nl/what-does-th...

No black marker was spared in the last response I received from the UK Cabinet Office based on my FOI request. Read the full story here: blog.koenvh.nl/my-continued...

My adventure with the UK Cabinet Office continues. tl;dr: they upheld their refusal and I made a complaint at the ICO. Find the full version here: blog.koenvh.nl/my-foi-adven...

Fun fact: in 2023, a total of 32 pupils were signed up for the central (Cito) Russian language exam. They came from 31 different schools. This is the same amount of pupils that were signed up for the Frysian language exam.

Voor degenen die de NLUUG najaarsconferentie gemist hebben en mijn talk willen terugkijken over e-mail, beveiligingsproblemen, en wat er gebeurt als de problemen meldt, de opname staat nu op YouTube: www.youtube.com/watch?v=Ct0M...

For those that missed my presentation about email spoofing and vulnerability disclosure at the ONE Conference 2023, it can now be watched back. The full report can be found here: surfdrive.surf.nl/files/index.... youtu.be/S-ZAzJrMqj0 (Ignore the subtitles, they are quite inaccurate)

Gisteren presenteerde ik over dit onderwerp bij #ONE2023. Mocht je het gemist hebben, de opnames komen later beschikbaar. De dia's zijn al wel hier te vinden: drive.google.com/file/d/11YGm...

Tomorrow I will be presenting at the #ONE2023 about what happens in practice if you do a large scale vulnerability disclosure. Whilst a lot of things go right, there is still a lot of room for improvement left. one-conference.nl/sessions/you...
