  • To be clear the failsafes barely did.

    Of the steps in this diagram the only one that prevented a nuclear detonation of the first bomb was the arming switch. In the swiss cheese model of accidents, out of 17 layers of protection, 16 failed. The safety mechanism that succeeded in this case had a history of failing because nuts in the plane could fall down and short the switch, arming the bomb unintentionally in flight.

    The pilots who bailed out were both arrested by base MPs for ‘stealing parachutes’ while trying to get to the base and warn about the unsafe condition of the crash site. It probably didn’t help that the first pilot to make it to base was black in NC in the 60s.



  • Cycle count is important for the lifetime estimate on the battery, how long before you have to spend a large portion of the cost of the car on replacing / refurbishing a key component.

    “Fill up” time is the most obvious and common ‘maintenance’ anyone will ever do on their vehicle. One of the biggest objections large swaths of the population have about EVs is/was that could take an hour or more for each stop on a long road trip or if you can’t charge at home. (apartment / street parking / etc.) They usually do 10-70%r 80 or whatever because the speed trails off exponentially closer to 100%. (logarithmically? whichever.)










  • Former healthcare IT, holy crap do all digital health records systems seem to suck. Some of them suck in different ways, but none of the big ones anyway are great.

    I get that there’s a lot of semi-special use cases and regulatory requirements and so on, but at the end of the day it’s text and images and a record of the changes to them. And it’s not like this is a surprise problem. People have been trying to digitize stuff since at least the 90s. And yet every single system seems like it’s only been in development for a few months and usually has trouble working with itself, much less any other record system.





  • Saying “my point is valid” does not make an argument valid. You’re presenting as a 2nd year computer science student who is mad because they just learned that Microsoft is less than trustworthy. Who read an article about toxoplasmosis recently.

    Most of the devices connecting to Home Assistant are using air gapped, non-wifi networks. A lot of them don’t have a TCP/IP stack, much less a radio capable of connecting to the internet.

    Home Assistant is an open source project. It’s not a thing constructed by a company for sale. You are in a lemmy instance talking about it, which is why the people reading a post about a version update to it, know what it is.

    Yes, there could be a magical way for “them” to secretly gather data on everything you do. But at that point they don’t need the smart devices.

    If you have trust, why do you need a blockchain?

    Distributed / immutable databases are not solely a feature of blockchain either.

    It’s a very interesting thing in a vacuum. Basically any application of it so far (with the possible exception of the original one, if it weren’t just a speculation investment machine at the moment) runs into the problem where it has to interact with reality at some point. And most of the problems Blockchains solve are already solved by a variety of other systems, for less time/currency/hardware investment.
