Because I have no idea if the questioner is going to do that beforehand

problem is a phone only works if you have it on you. Grandma falling often is a case where she doesn’t have a phone (often grandma in this case is in mental decline and wouldn’t think to use the phone if she had it).

A privacy respecting device that can hear “help” and general cries/grunts to get help when needed is what the world really needs. This is much more complex than the ask, but it is the real need here. For me what the OP was asking is enough, I just need to inform a kid in a different room dinner is ready.

A local hackerspace will probably take pity on you and find someone to do this for you.

You can get just enough energy for a science fair demonstration. Which scaled up to a data center size is a lot of energy. What the science fair misses is how much energy goes into making the system - You can generate what looks like a lot of power until you realize that the generators and such needed more energy to make than you will get back.

I miss old Usenet forums. They actually worked better because they had the concept of, you’ve already seen this message, you don’t have to read it again. And so you could go back and actually have longer conversations over time because you weren’t constantly trying to figure out what to read next. Some of the forums I’ve used I’m trying to do this however they don’t do it nearly as well because it’s more like you’ve read this far up in this page and so if you start reading and then use and there are multiple posts and you run out of time you eventually reach quite where you’ve closed a tab and when you come back it assumes you’ve read things you haven’t.

It looks either AI, or a combination of pictures via Photoshop. I’m guessing AI, but hard to know for sure.

The first row is cooling towers. The second I’m not sure of but suspect not. The last is coal (could be other things, but it looks like other coal plants I’ve seen)

When IPv6 was first created, the dream was that your machine would get a new IP address any time the whole network felt some need for that. The idea was, as someone added a network, we may need to change the way your systems are numbered in order to make the backbone routing a lot easier to fit in memory. This hasn’t seemed to work out, but that was the dream.

I assume your ZFS system has plenty of redundancy. Thus, I would enable snapshots and do a regular rotation because ZFS snapshots are so easy to recover from for most disasters. What that leaves is the catastrophic losses from, say, your house burning down. So you still need something off-site, but the ZFS will cover most of your backup needs.

I did the monthly arch upgrade and had to reboot to get some service to come up. Took an extra 5 minutes this month.

It might be but it is risky - if anything goes wrong there goes that data.

The problem is people don’t want a focused community. They want a broad community so when they have a question they can ask and find an expert - but not so broad that the noise means they can’t follow anything. We do focused communities because the world (or even internet) has too many people and so the noise of all the discussions is too much. However that isn’t what we want.

I bought a used EV, and the loan is massive and more than I can afford (but I didn’t have a choice - my area is car dependent and I go many places too far for my bike)

don’t label with panel slot - too often you need to move things and so those are incorrect anyway

the box needs to be accessable. The drop ceilling counts but something perminant ceiling would not.

If one dimmable color (or color change to red on dim) is not enough then you need room lights and spicial effects lights as separate things.

N100. Cheap enough (last year) and plenty of power to run things like jellyfin on it as well. linuxserver makes great docker images.

The kernel doesn’t deal with DNS, that is a separate process/library

General advice is smart switches, dumb bulbs. Switches mean that you can control the light without getting out your phone, or whatever it is you use to control the bulb. Sure HA can talk to many bulbs, but only if the switch is on. Guests will not have the ability to control your bulbs - either there is too much work to install an app for a short stay, or the system is a security nightmare (often both). Use a smart switch because they have a control on the wall that guests can use to get what they want done without having to worry about apps.

Most often you can choose bulbs with the right color temperature, but if not some dimable bulbs change color temperature. If this is not good enough two lights: a general room like, and a separate special effects light, don’t combine them (HA can control both, but they are separate systems generally not used at the same time)

What is the point of it? If the are doesn’t cryptographically trace to the right birth certificate for who is at the keyboard now it won’t do anything - kids will lie about age if there is any issues. If it does trace back that well there are huge privacy problems.
