Rsync can rename/move target changed or gone from the source.

I use those options so that I get a separate ‘archive’ dir next to my backup target, with old versions of files.

It’s useful for loose collections such as photos.

Maybe because it has Windows inside it :)

I think I get more of what you mean, now. I’m sure that there are technical issues to solve, like you said from the start, but that doesn’t mean they can’t be solved.

Realistically that single sent packet is going to get copied multiple times in order to re-route it just to the subscribers. We’re not all one one big LAN.

What mechanism causes a single sent packet to get to all the subscribers (and only them)?

Assuming that we all have a static IP for simplicity, a sent packet needs to be routed to the subscriber IPs (via their ISPs). Where is that table stored? Is it sent with each packet so that it can be routed on the way? That would be a huge bloat of the packet size.

BTW, I do remember life before VCRs. Pre internet, I downloaded QWK packets from BBSs.

I get the appeal of removing communication from the hands of FB etc, but I don’t see how switching to a broadcast system that increases unreliably would help. And I don’t see how the broadcast would work on the Internet that we have.

So when a video is created it is immediately sent to subscribers?

In that case, for things to be sent once, it relies on the receivers always being online. That doesn’t work if my laptop is closed at the time.

That’s why I’m thinking that it needs online caching to work. Or everyone has a cloud server that handles sending and receiving while they’re not online.

In fact, that starts to sound like everyone running their own personal lemmy-like instance, to which their friends subscribe.

And in that case it wouldn’t matter if messages were sent more than once, each person’s server would handle it.

I just thought that it worked well with as a static image.

But maybe someone had a bit of fun doing that divider effect.

I see I misunderstood how you mean this to work, that routing would handle sending data only to subscribers. I was imagining that it mean a simple LAN broadcast using a packet with the subnet bits all set (e.g. 192.168.255.255). I think that it’s more analogous to a mailing list distribution, but for general data/streams?

But your earlier example of downloading the cat video still fails unless many people request the video at the same time (otherwise you’re multicasting to one). What happens if I watch the video on my phone while out, then watch it again on my laptop at home? It will still need sending twice.

Wouldn’t a more efficient approach just be to have something like ipfs with lots of local caching?

I don’t see how that would work. So all my friends video streams, for instance, would be streaming data to all my devices as they are broadcast.

But my laptop is currently asleep. It wouldn’t receive anything.

How do you solve that without storing the video on a server that I can pull from on demand?

Even for my devices that are on, they’d have to store everything as it was broadcast.

And the streams (including every other broadcast) would constantly be eating up my bandwidth.

How would I not receive streams that I’m not interested in? What would decide which broadcast packets do or don’t get sent to my router?

That’s what I’m saying, both versions show both outlines.

The coloring changes, but both show the same information.

Yes, GPS works by measuring your distance from several GPS satellites (based on the timing of the signals they send). If a few distances are known, it narrows it down to a point (the satellite orbits are known so you know where they are at any time).

I’ve owned several stand-alone GPS receivers before phones started to include the feature.

You can download offline maps to phones so that you can navigate without any phone signal.

Why does the map on the website need that draggable divider when both versions show both types of projection?

It was that channel!

And it was the wolfbox. I didn’t mention it because I didn’t want to appear to be shilling a particular product.

I got a battery-powered air blower after seeing a YouTube video comparing and reviewing them.

I’ve always joked about how stupid leaf blower are, but I’ve found this pocket-sized version really useful.

Cleaning out dust from computers, tower fans, etc, it is amazing.

I also have a small dust buster and this blower gets its filter really clean like nothing else can.

Unlike cans of compressed gas, there’s no concern about inhaling anything if I use it indoors, or getting frostbite when the can cools.

I’ve seen people discussing a cellphone offer that’s like “$800 but you get $800 of bill credits over 24 months” and they would say it’s a free phone. But you’d pay $800 plus tax up front and you’d not get that tax back.

Still a good deal, but it showed how many people were blind to the tax.

And there’s are those gadgets that have a USB-C socket but don’t have the correct circuitry, so that they only work with a USB-A to C cable.

Oh, many years ago I had a baby monitor that included a pressure mat. If it detected no movement for a while (it was sensitive enough to detect breathing) it set off an alarm.

Although if such a thing exists today, it probably requires an app and a subscription. Enshitification.

Looks like the pixel watch 3 can do something like this, but it only calls emergency services (and plant l only in some regions!)

I see some end in a thin pin or are short. I was thinking of the ones that are the full size of a plug, of course.
