There are, and I think the only real difference has been the community support. The community was behind the original pi and the guides, images and support show that, and it continues to this day.
If this becomes "enshittified" then communities will grow around the alternatives, it's likely there will be an overall winner (or winners per class) and we'll move on. The device itself wasn't ever the whole story.
I'm fairly sure it must take extra work to make dynamic prefixes. I've heard some weird justifications about localised routing. But modern ISPs generally don't work that way at all. For example, my ISP has endpoints in multiple cities, and can fail over to another city if need be. All my static IPv4 and IPv6 instantly move with me in that event.
You can get non VPN tunnels. I used both Hurricane electric (https://tunnelbroker.net) and sixxs (https://www.sixxs.net). I believe sixxs stopped offering services in 2017 though.
I'm lucky that I have a choice of multiple ISPs all offering service on gigabit symmetric fibre. I've managed to keep my old setup of a /29 IPv4 allocation and /48 IPv6 allocation. But before IPv6 was available, I used tunnels at the point of the router with no problem. As such, the internal network doesn't need to know there's a tunnel and gets native IPv6.
I've seen a few isps here in the UK doing some weird pointless stuff with ipv6. Like dynamic prefixes. Why? What's the point?
But you can get good ones. I've had the same /48 prefix for 10 years now.
There's literally nothing stopping a moderately skilled IT team from integrating ipv6. You can run any site easily using both. The exceptions are few and even those aren't that hard to deal with.
Source: been running dual ipv4/ipv6 Web servers for over 10 years (maybe 15 would need to check) . Likewise had ipv6 dual stack at home for a similar amount of time, initially using tunnels and then native.
Almost every server provider will give you ipv6 for free. There's really no excuse these days not to run your services on both protocols now.
I always saw open source as more socialist than specifically communist. Similar to volunteering in your community. Except the community is the whole world, and you don't need to leave your house. Bonus!
The S24 (all versions) didn't.
I'm in the ntppool.org pool for the UK. It randomly assigns servers which could be any stratum really (but there is quality control on the time provided). I also have stratum 2 servers in .fi, and .fr (which are dedicated servers I also use for other things, rather than a raspberry pi).
No. A GPS (with PPS) hat. That counts as a stratum 0 time source, making the NTP server stratum 1.
Well I run an ntp stratum 1 server handling 2800 requests a second on average (3.6mbit/s total average traffic), and a flight radar24 reporting station, plus some other rarely used services.
The fan only comes on during boot, I've never heard it used in normal operation. Load averages 0.3-0.5. Most of that is Fr24. Chrony takes <5% of a single core usually.
It's pretty capable.
Given that God is infinite, and that the universe is also infinite. Would you like a toasted teacake?
I mean if LLM/Diffusion type AI is a dead-end and the extra investment happening now doesn't lead anywhere beyond that. Yes, likely the bubble will burst.
But, this kind of investment could create something else. We'll see. I'm 50/50 on the potential of it myself. I think it's more likely a lot of loud talking con artists will soak up all the investment and deliver nothing.
