  • How do things outside the LAN talk to things inside the LAN that have ULA addresses. . .?

    One big conceptual difference between IPv4 and IPv6 is the notion that any single host on the network is expected to have multiple, simultaneously-useful IPv6 addresses and this is totally normal and fine.

    Any IPv6-enabled host is necessarily going to have a link-local address which can only be used to communicate with other hosts on the local network/subnet.

    If your ISP offers IPv6 connectivity, or if you’ve set up an IPv6 tunnel from an IPv6 tunnel provider then a host on your network will also have a globally-routable IPv6 address which was assigned from your router via DHCPv6 or (more commonly) self-assigned using SLAAC (Stateless Address Autoconfiguration) which is an IPv6 way for machines to self-assign addresses is a sane, interoperable way without requiring a setup and operation of a service like DHCP(v6). Many IPv6 networks do not need to use run a DHCPv6 server at all and rely solely on SLAAC host self-assignments and local IPv6 router discovery protocols to find DNS servers and eligible gateways to other networks and the internet at large.

    The block of IPv6 addresses used for your local machines is delegated by your ISP or tunnel provider. It can be static or dynamic and the underlying protocols will handle if that network range changes. IPv6 generally is tolerant of a host’s public IP addresses changing at any time without disrupting connections or services.

    With privacy extensions (enabled by default on all mainstream operating systems) a host on your network might have additional publicly-routable addresses which rotate frequently for privacy. Outbound traffic for the host will prefer these more private addresses for new connections. These addresses are ephemeral and change frequently.

    In rare cases you might set up ULA addresses which are static and usable on your internal networks but will not be routed to the internet. They can be used for hosting services on your local network which need to potentially span multiple subnets/VLANs and in particular are useful for internal resources like name servers which cannot rely on DNS lookups for address resolution. Most networks will not use ULA addresses and normal use cases do not require them.

    At any given moment, an IPv6-enabled host will have multiple active addresses all used for different types of traffic and it’s important to break any assumptions you have carried over from IPv4 about the relationship between IP addresses and hosts on the network. Your host might be using a link local address to talk to another machine on a shared internal subnet while also using temporary, globally-routable IP privacy address to talk to a server on the internet. Multiple addresses can be in use at the same time to reach different endpoints in the world.



  • … when there’s literally no other option to own it in a way it can’t be just taken from you …

    There’s at least one legal route that’s still viable.

    I buy lots of Blu-ray and 4K UHD discs. I rip them straight on to my Jellyfin server. In fact, there’s been renewed vitality in disc releases during the past few years. Small shops like Shout Factory and Arrow are buying rights to old (‘60s through ‘00s) films that were shot on 35mm. They re-scan and remaster for UHD 4K and then straight to physical disc. That’s a cheap production pipeline with modern tech.

    I’ve been having a blast re-visiting films that I never saw in the theater and only know from VHS or DVD rentals. Seeing them again with fresh eyes in 4K has been really gratifying.

    That, plus new release discs keep me with more options than I have time to watch.


  • Is AI in this ethical and sustainable AI?

    It’s possible to make use of the full suite of HA AI tooling with entirely open source, on-premises, behind-the-firewall resources. That’s actually damn awesome and can do some cool things. There’s a lot you can do on a Raspberry Pi or an old Apple Silicon Mac, it doesn’t take a lot of hardware for basic stuff. Ambitious usage is going to drive you to into a budget on par with “Gaming PC.”

    You can set up complex AI automation flows and voice assistant interactions without giving a penny to any of the many “ai” companies you might not want to support.

    People are, in general, still boiling the oceans to produce all those interesting models you can run. Indirectly, you’re sustaining that activity by giving it interest and inertia.

    Where do you draw your line?



  • “Vietnam” is not widely known for sex tourism, but “Southeast Asia” is coded. “Sex Tourism in Southeast Asia” is a familiar term in American English and the image caption is tailored to leverage that association. This image was created to be misinformation and the creator chose the phrasing to increase the image’s impact.












  • I never said I have the breadth of your personality. But I sure as shit have some opinions at this point about what it’s like to interact with you online.

    Then honestly I don’t really care about what you think.

    Perhaps not me personally but you’ve expressed elsewhere in the comments that you do care about the reaction you’ve received from this community. You’ve expressed frustration at the replies and downvotes you’ve received.

    The lemmy mob I’m referencing is actually more of a downvote campaign… it’s the same group of people nearly every time.

    I’m suggesting that it might not be about your views specifically and more about how you choose to interact with the other people here.



  • The iPad will last a whole movies worth of time streaming a screen mirror? That’s impressive I guess.

    I’m struggling to figure out what you’re trying to communicate here. I mean, yeah, probably. The iPad is notorious for its class-leading battery life under real usage. But you know, it can also be plugged into the wall with any USB-C charger. It’s weird to me that you’d even bring this up.

    I’ve seen you mention in several posts that you’re frustrated by the unfriendly response you perceive from this community. Have you ever considered that it might be your personality and not your views that’s causing it?

    Edit: No, I have no difficulties reaching local devices while connected to my VPN.
