On the night of 25–26 May 2021 vaccination registration opened for my age group. Before that I checked the status of my earlier registration (when only the highest-risk groups could register, it had been possible to register by manipulating input parameters due to missing validat...
I needed to solve a tricky problem — I have two computers (actually three, but two of them are work machines) and I need to work on them comfortably. Essentially the same issue I once had at a government office, where you had three machines each assigned to something di...
