GPS, GLONASS, Galileo, BeiDou (Global Navigational Satellite Systems, GNSS) are miracles of engineering. And within any complex system hide surprises and unsuspected complications. In this post I go over how we resolved an odd observation: that everyone (including major institutions) reported that one of the Galileo...

Hi everyone, Disclaimer: this is a review of a free sample I got sent by Uputronics. I recently spotted on Twitter that Uputronics had launched a GPS/RTS Raspberry Pi Expansion Board, and that they were looking for worthy projects to test it. I thought our Galileo/GPS/BeiDou/GLONASS monitoring project galmon.eu...

I have a longer story brewing, but in this post I want to briefly announce the “Galmon.eu unofficial Weekly Performance Report”. This is a blog post version of an earlier Twitter thread. I’m very proud to present the first full Galmon.eu Weekly Galileo Report! And the good news is: it was a good week with very...

Nu het RIVM gestopt is met dagelijkse updates vond ik dat het tijd was dat gat dan maar te vullen, al is het maar voor een dag. Een nieuwe Corona Update “hoe gaat het nu met”. De vorige was alweer van 21 april! De “Ik ben geen expert, maar toch”-factor Een boel dansleraren en opiniepeilers zijn inmiddels COVID-19...

When COVID-19 burst on to the scene, tests quickly showed that the everyone was susceptible - no pre-existing antibodies were found that bound to the SARS-CoV-2 virus. This led to dire predictions that over 80% of the population might eventually fall ill. Now more than six months in, this has not happened, and it...

Welcome to this post, in which we’ll be taking a trip through the wild and bumpy ride that has been Vitamin D & sunlight research over the past few decades, and what it might mean for COVID-19. As with my previous post, before any non-specialist attempts to write something on COVID-19, we should wonder: are any...

It turns out that so far, I have written over 44000 words on COVID-19. I’ve tried very hard to only report the best and most trustworthy science, but I did strive to include interesting new insights that were not yet mainstream. As an example, I spoke about vitamin D and sunlight real early, which now indeed appears...

This post is dedicated to lab technicians everywhere doing the difficult work institutes and hospitals rely on to investigate disease and keep us healthy. Lab work requires high precision, deep understanding, is physically demanding, and can even be dangerous. Although our healthcare systems & universities would...

Before any non-specialist attempts to write something on COVID-19, we should wonder: are any actual experts already writing on this, and if not, why not. Enough badly informed stuff has already been published by amateurs that before posting we should be certain we are actually being helpful. October 2022 UPDATE:...

Een spontane wetenschapsupdate, omdat het Moederdag is, en speciaal voor iedereen die het nu zonder zijn of haar moeder moet doen. Want, we dragen allemaal letterlijk een beetje onze moeder bij ons! Deze post is dankbaar geïnspireerd door deze Twitter thread van Efra Rivera-Serrano, PhD. Bron: Efra Rivera-Serrano,...

Het RIVM, het “Outbreak Management Team” en het kabinet werken samen aan gedegen adviezen. Uiteindelijk worden dit ook wel de juiste adviezen, al blijft men soms lang aan oude dingen hangen: mensen zonder symptomen zijn niet besmettelijk (oeps, toch wel), maskers hebben geen zin (oeps, ze helpen wel voorkomen dat je...

Ik blog al maanden over SARS-CoV-2 aka COVID-19 aka “het coronavirus”, waarbij ik grotendeels dingen uitleg en verwijs naar positieve ontwikkelingen. Ook zijn er stukjes over medische experimenten, over ons immuunsysteem en recent iets korts over het vermoedelijke belang van goede ventilatie om COVID-19 besmettingen...
