Gamer, developer, dad.

Welcome to my site/blog/diary. I’m a 40 year old gamer, (opiniated) developer and a dad, not necessarily in that order ;) . I live in the Netherlands together with my wife and kids.

I’ve been gaming and programming since I bought my first computer at the age of 11: and MSX. A couple of years later I started an education for software engineer and got a PC, a good old 486.

I work for one of the largest Email Service Providers in the Netherlands. I’ve been working there for over 15 years now as a developer, system administrator and deliverability specialist.

Opinions are my own.

Starting MSX assembly part 1

Published at May 5, 2019 ·  4 min read

I somehow get the feeling every now and then that more people want to know how to program things for old computers. Since I still have a working MSX and still sometimes program for it, let’s see if I can create some tutorials. Assembler The MSX has a Z80 processor on board. So you need a Z80 assembler if you want to program in assembly. You can use an assembler on the MSX like Wbass-2 or Compass, or you can use a PC or Mac for cross-development and use something like Sjasm or Glass....

So to actually do that, I started this blog. Being a software developer I wanted to create it myself of cource. So the first thing to do was to search for software or a framework to create the site in....

Splitting a video in a grid of videos

Published at November 24, 2018 ·  5 min read

Recently we had a nice idea for the soft-launch of our new website for the company I work for. In a symbolic way we let almost everyone take part by using their phones to display a part of the video. In the end we had 49 phones in a 7x7 grid displaying a video with a countdown timer, showing the new website afterwards. Pictures to video The video was made with just still pictures, ffmpeg-concat and the commandline tool FFMPEG....
