Yeah, if the ones and zeros arent in your drive, it can disappear at any point from the internet.

You can add IPS to port to add some security checking, but yes, in general port is never secure or unsecure.

Coral Acceletor is only needed if you run setup that does not have GPU or enough CPU. Spare laptop usually has enough power to handle AI detection, but RasPi doesn’t. I run mine in CPU at rack server.

Cameras own detections are limited in my experience, and it is much harder to integrate to anything else, like HomeAssistant for notification & automation

HomeAssistant + Frigate combo is just plain awesome. You can leverage the automations of HA through Frigate’s AI detection, so you get things like notifications.

I would suggest more learn by doing approach. Learning OSI model etc is nice, but it is quite jargon :)

Use some old PC as a server, and get some network cards into it, and use it as firewall/router. Route your home network/NAT/DNS/DCHP through it. Raspberry Pi’s are nice, but their hw is still bit limited.

OPNSense is quite nice and easy free and open source firewall/router solution.

If you want to add bit of flexibility, you can use some virtualization platform like VMware in to the machine, so that you can run OPNSense in it, with some other virtual servers.

Then when you get things working, you can start looking in to VLAN’s, because they are quite important part of enterprise networking. Most cheap switches nowadays support VLAN’s out of the box.

I use rasp as Bluetooth receiver for my home assistant sensors (Ruuvi tags mainly)

You can use Greasemonkey plugin in your browser to modify link behavior of Lemmy instances web page. Should not be too complex script.

Lemmy.world is already quite large, for decentralization it would be better if people would use other instances and balance the sizes.

Ok, it seems that I was wrong, standard seems to allow it. So both ! and / are allowed in email

but these solutions would not have saved my clumsy ass in the original case.

If instance would have been fictional furryporn.com and community is called worldnews, and I sent to my grandmother a message containing community url !worldnews@furryporn.com, it would not really matter is it in form of c/worldnews@furryporn.com or with !

I would maybe say that c/community@instance.com and u/user@instance.com could be better. / is not legal character on email address, but so is of course ! in the front. c/ and u/ would make sense because that is the actual url that is fetched (c/community@instance.com is located in https://instance.com/c/community), so in code just combining these two paths together would generate the actual URL.

Of course changing it at this point in time of the life cycle is probably a no-go.

Does lemmynsfw.com and pornlemmy.com federate?
