  • 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.





  • My recommendation is Lumibricks or Pantasy. They’re not quite 1/3 of the price of Lego, more around 1/2 on average I think, but both offer the best brick quality that you’re going to get from any company at the moment (they use the same supplier, gobricks). They’re also both offering exclusively original designs, so no copied sets or anything like that, and doing a lot of stuff setting them apart from Lego. Lumibricks has light kits integrated seamlessly into every set and goes hard on printed pieces, no stickers anywhere. Pantasy likes using lots of metallic painted pieces, bigger custom molded pieces, and has a few interesting IPs.

    If you’re into Technic, there’s also CaDa, and if you want very accurate display models you could look into Cobi. The later is a polish company that designs and produces entirely in Europe, in contrast to any other brand out there, but that also comes with a price tag that’s pretty similar to Lego at this point.






  • You’re not wrong, but the way you put it makes it sound a little bit too intentional, I think. It’s not like the camera sees infrared light and makes a deliberate choice to display it as purple. The camera sensor has red, green and blue pixels, and it just so happens that these pixels are receptive to a wider range of the light spectrum than the human eye equivalent, including some infrared. Infrared light apparently triggers the pixels in roughly the same way that purple light does, and the sensor can’t distinguish between infrared light and light that actually appears purple to humans, so that’s why it shows up like that. It’s just an accidental byproduct of how camera sensors work, and the budgetary decision to not include an infrared filter in the lens to prevent it from happening.
