  • I have an anecdote that says the opposite. I got the same fridge, washer, and dryer from LG when we moved in our house 10 years ago and have had no problems with any one of them. My wife hates that we got a model with the freezer as a drawer on the bottom and would have preferred a side by side but no problems with anything breaking.

    Our Bosch dishwasher on the other hand had a gasket start leaking during the pandemic and it took the repair people 4 or 5 months to get a replacement in. I think they were redesigning a faulty part at the same time as all the supply chain issues so we had a really bad time with that. It was only a couple years old at the time and has worked ever since.


  • You have a point that it will be hard to explain this to everyone on why it is better.

    From my understanding, when you use a password manager, the user will enter a pw into it that they remember and the vault will unlock. Then when they go to log into a website, a different, longer, and impossible to remember password will be sent to the site at login. (Assuming they are using the manager well). A week later when they go to log in again, the same long password will be delivered.

    The problem is that if a bad actor gets involved, whether it is the website is attacked or they send the user a phishing url or something and the password from the manager is exposed, it will have to be changed. That scammer can now log into that website as the user whenever they want, and possibly any other website that user used the same password for. Hopefully they didn’t if they are using a manager.

    With passkeys, a user will log into their manager with a password they remember, but when they go to log into a website, a different token will be sent, based on their key, every time. So if a scammer is listening at the router they still can’t log in again because it has expired.

    It is still not a perfect thing, I would imagine that phishing sites could still get a scammer in, who could possibly do bad things or change the login credentials but it is still much more secure than sending a password to the site for the user.





  • You are correct that if you are on thee moon and have a cs-133 atom with you is second will take that many transitions. And if you do the same thing on Earth, a second will take the same number of transitions.

    But things get weird when you are on earth and observe a cs-133 atom that is on the moon. Because you are in different reference frames, you are traveling at different speeds and are in different gravity wells time is moving at different rates. This means that a cs atom locally will transition a different number of times in a second from your point of view on Earth vs one you are observing on the moon.

    And it would all be reversed if you were on the Moon observing a clock back on the Earth.

    They already have to account for this with GPS satellites. They all have atomic clocks on them but they don’t run at the same speed as clocks that are on the ground. The satellites are moving at a great speed and are further from the center of the earth than us, so the software that calculates the distance from your phone to the satellite have to use Einstein’s equations to account for the change in the rate of time.

    Relativity is weird.
