"Success always demands a greater effort."

Thanks for visiting my website. It is a mix of personal interests and professional experience.

My professional background is focused on software quality assurance, but not just pointing and clicking! My approach to quality assurance is engineering based with an emphasis on "pushing left" and building teams from the "ground up". This means understanding the importance of being involved early in the software development lifecycle, being able to create detailed documentation, reliable processes, automating error-prone, mission critical and mundane tests, as well as harnessing human strengths (like exploratory testing).

I also have speaking experience on a variety of topics software quality assurance-related. My contact information is in the footer if you are interested in having me speak at an event.

When I'm not being a software quality assurance guru I enjoy a variety of activities, some of which are represented on my website. I like making craft cocktails , building things , and listening to podcasts.

Keogram: The Sky in 2025

What if you could see the entire sky -- all at once -- for an entire year? That, very nearly, is what is pictured here. Every 15 seconds during 2025, an all-sky camera took an image of the sky over the Netherlands. Central columns from these images were then aligned and combined to create the featured keogram, with January at the top, December at the bottom, and the middle of the night running vertically just left of center. What do we see? Most obviously, the daytime sky is mostly blue, while the nighttime sky is mostly black. The twelve light bands crossing the night sky are caused by the glow of the Moon. The thinnest part of the black hourglass shape occurs during the summer solstice, like today, when days are the longest, while the thickest part occurs at the winter solstice. Equinoxes can also be located in the keogram, for example the northern-spring equinox from one year ago is about three-quarters of the way up.
