Ik heb hier een Twitter-draadje van Patricia Bruijning omgezet naar een webpagina, waardoor het verhaal wat makkelijker te lezen is voor mensen zonder Twitter. Dr Bruijning is Universitair Hoofddocent epidemiologie bij UMC Utrecht maar...
Ja, daar zijn we weer! Voor het eerst [sinds juli](https://berthub.eu/articles/posts/corona-update-eind-juli/) weer een Corona Update. Er is inmiddels weer genoeg te melden: vaccins, tests, cijfers, medicijnen en vitamine D. Vaccins Om...
As the world focuses on the terrible (but improving) Dutch COVID-19 numbers, I also see a lot of people interpreting the numbers badly. But we can hardly blame folks since most data is only described in Dutch. And even in Dutch the...
Don’t take this too seriously. As part of my coping mechanisms, I try to understand the latest (Dutch) COVID-19 figures. I documented where to get the raw data and what they mean in an earlier post. Please note I am not trying to make...
Around a million years ago (it feels like) but actually 9 months ago I delivered a brief talk on end to end encryption for the European Internet Forum at the European Parliament. Update: in February 2024, the European Court of Human...
The European Global Navigation Satellite System Galileo has recently been suffering from frequent "almost disruptions", most likely partially due to Corona, and possibly also due to Brexit, but in any case due to some historical...
Welcome to part 3 of my series on OSNMA, the proposed Galileo Navigation Message Authentication protocol. This part can be read independently from part 1 and part 2, but it might be useful to read the introduction to part 1. This post...
We horen veel over hoeveel mensen er nu besmet raken met COVID-19. Tegelijk viel het tot begin oktober erg mee met de ziekenhuisopnames en sterfgevallen. Ik kan ook niet verklaren hoe dat precies komt (het is niet alleen leeftijd), maar...
Recapping from part 1: Galileo will soon add cryptographic signatures to the navigation messages. These cryptographic signatures are made with symmetric cryptography, which means clever techniques are required to prevent receivers from...
Position, velocity and time (PVT) information can be a ’nice to have’, but in other circumstances knowing place and time has legal or military importance as well. Heavy vehicles for example are typically outfitted with tachographs that...
Toch weer een kleine Corona-update, vrij snel na de vorige van 1 juli. Want poeh, gaat het nou ineens weer mis in Nederland? Of valt het mee? Moeten we allemaal aan de maskers en komt het dan goed? En gaan de vaccins en medicijnen ons...
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...
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...
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...
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,...
