  • even if you steal my password (database)

    That’s a big leap you’re doing there, equating stealing a password to stealing a password database. Those are very different. Stealing a password can be done through regular phishing, or a host of other methods that don’t require targeted effort. Stealing a password database, if properly set up, is a lot harder than that. It depends of course on what password manager you’re using, but it usually involves multiple factors itself. So equating that to just a password, no matter how strong and random, is just misleading.

    Mind you, I agree that it’s less secure than “proper” MFA, and I’m not saying that everybody should just use MFA through a PW manager. I am using physical security keys myself. But for a lot of regular people that otherwise just couldn’t be bothered, it’s absolutely a viable alternative that makes them a whole lot safer for comparatively little effort. Telling them they just shouldn’t bother at all is just going to create more victims. There is no such thing as perfect security, and everyone has a different risk profile.





  • For electric heating, you basically only have two options, heat pumps and resistive. Within just that comparison, 100% is the lower limit.

    If you want to compare it to other types of heating, efficiency becomes much harder to measure, because the inputs can differ.

    If you’re using electricity generated by burning fossil fuels it’s simple enough, but the “100% efficient” resistive heating loses again because you could just burn the same fossil fuels in your home to heat it directly which is much more efficient.

    If you’re using renewable power, then “efficiency” kinda becomes meaningless because you’re using entirely different resources to produce the heat, so you can only try to abstract it by using either money or environmental impact per unit of heat as a stand-in. I don’t have the numbers on it right now so correct me if I’m wrong, but I think resistive heating would actually be more expensive than fossil-fuel based heating, generally speaking - there’s a reason that it’s not really a wide-spread thing for heating whole homes.

    So unless I’m wrong on something here, resistive heating is really not going to be among the most efficient options, unless you specifically only look at environmental impact and are using regenerative sources for it. But even then, the heat pump just wins by miles.





  • if you are entitled to using a paid version for free (e. g. students, educators) you cannot opt-out of sharing your code.

    That is incorrect. According to the page you linked elsewhere:

    For individuals on non-commercial licenses: Data sharing is enabled by default, but you can turn it off anytime in the settings.

    (Emphasis mine)

    And for all other cases it’s opt-in. No idea how you got from that that you cannot opt-out. It literally says the opposite.



  • Not in Germany. The amount of vacation is based on the amount of days you work, not the hours. The goal is that everyone should be able to take at least a total of 4 weeks off per year. That means you get 20 days of vacation if you work a regular 5 day week. If you work a 6 day week, you get 24, but that is pretty unusual.

    So, if you work fewer hours, that only matters for your vacation if those hours are also done across fewer days. If you only work 10 hours a week, but spread them across all five days, you still need 5 days to take an entire week off, so you still get the 20 days.

    But anyway most employers will give you closer to 30 anyway, so the legal minimum usually only matters when it comes to things like transferring to the next year or paying out untaken vacation, because the rules differ there between mandatory and additional vacation days




  • Responding to your edit:

    You’ve got it the wrong way around. What you see at sunset, the reds and yellows, that’s the sunlight being filtered because those wavelengths make it through stronger. Your argument would hold there, if we do not count seeing filtered light as “seeing” the filtering material. (Although even that I’d question - if you hold a colored piece of glass against a light source so it’s entirely backlit, would you say you’re not seeing it?)

    But the blue sky is not that. It is the air molecules being illuminated by light coming from somewhere else, and bouncing that light back into your eyes, with a bias towards blue wavelengths. If that does not count as “seeing” air, then you also can’t actually “see” fog, it’s the same mechanism.
