Tangentially, just yesterday I traveled with an old train from Oslo and one thing that I notice again and again there is the sliding glass doors between the train cars have a "button" on them that does nothing except when you reach out to touch it you trigger a photosensor. So it feels like the door anticipates you.

I remember those. It was quite disconcerting the first time. But when I thought about the engineering involved I was really impressed by the solution.

It's amazing that pathogens capable of living on surfaces haven't wiped us out already. Thanks immune system.

Doorknobs and handrails in public buildings transitioned from wood and stone, to polished metal during/after the 1918 pandemic. Turns out wood is a fantastic, warm material to make doorknobs and handrails from, but it's almost impossible to clean and sanitize in a functional fashion.

Metals are not all equal in that either. Stainless steel is markedly worse than brass for door handles. Clean brass is antimicrobial and also kills influenza and other viruses.

Anybody know how to get reliable hosting after your inevitable death?

The main reason I'm looking forward to being dead is that I will no longer have to worry about whether some website is working or not.

I like your take on that but I have automated my house, self-host and have a family. To whom I enforced 2Fa for key applications.

It means that if I died they will be in an ocean of trouble if I did not take steps to facilitate the transition.

The first part is to have a paper backup of everything important, and keep it up to date.

The second, requested by my wife, is a tutorial on how to de-automate the house and what things they should worry most about (moving the self-hosted Bitwarden and making sure domains and email are paid for).

This preparation doe not bother me at all on the emotional level but rather on the documentation one...

Amazingly brass has antimicrobial properties.

So does silver, to the point it’s used in advanced wound dressing. They aren’t cheap though - ask my insurance company! There isn’t that much silver in them, but a 2x2” square is about $4 or so, compared to a few cents for a plain gauze pad.

Silver is 0.72 USD/g at the moment so the price of silver alone does not account for the difference in price. A two inch square piece of silver weighing a gram would be more than a tenth of a millimetre thick.

So few. Im at work right now and I think i've opened at least 15 doors just between my bed and my desk. It was five doors just between my bedroom and my car. (bedroom door, out apartment, into stairwell, out of stairwell, out of building). Then car doors, security gates, building external, internal hallways, into my department, into my section, into my office ... I guess I live in a door-heavy environment.

Have those on trains in Sweden too. All the veteran commuters just wave their hands in front of the sensor instead of trying to push the "button".
