…are Turing Complete, so what you can do with them is exactly equal.
But they’re only equal in the Turing complete sense, which (iirc) says nothing about performance or timing.

Can we please not do this on Lemmy? Pun comment threads are just the wurst.
Because not all humans strive for honor.
Yep, you’re right — I was just responding to parent’s comment about fiber being best because nothing is faster than light :)
That’s…not really a cogent argument.
Satellites connect to ground using radio/microwave (or even laser), all of which are electromagnetic radiation and travel at the speed of light (in vacuum).
Light in a fiber travels much more slowly than in vacuum — light in fiber travels at around 67% the speed of light in vacuum (depends on the fiber). In contrast, signals through cat7 twisted pair (Ethernet) can be north of 75%, and coaxial cable can be north of 80% (even higher for air dielectric). Note that these are all carrying electromagnetic waves, they’re just a) not in free space and b) generally not optical frequency, so we don’t call them light, but they are still governed by the same equations and limitations.
If you want to get signals from point A to point B fastest (lowest latency), you don’t use fiber, you probably use microwaves: https://arstechnica.com/information-technology/2016/11/private-microwave-networks-financial-hft/
Finally, the reason fiber is so good is complicated, but has to do with the fact that “physics bandwidth” tends to care about fractional bandwidth (“delta frequency divided by frequency”), whereas “information bandwidth” cares about absolute bandwidth (“delta frequency”), all else being equal (looking at you, SNR). Fiber uses optical frequencies, which can be hundreds of THz — so a tiny fractional bandwidth is a huge absolute bandwidth.
80% of the USA lives within urban areas (source). Urban “fiberization” is absolutely within reach.
Agree that running fiber out to very remote areas is tricky, but even then it’s probably not prohibitive for all but the most remote locations.
The CW folks would presumably be sending QTH instead — I wonder if this graph captures that/if it would make an appreciable difference?
So the irony is
I see what you did there…
I think you mean more scrupulous, not less.
Hopefully you can publish in an open-access journal — if not it would be great if you could share an arXiv preprint :)

I think the same is true for a lot of folks and self hosting. Sure, having data in our own hands is great, and yes avoiding vendor lock-in is nice. But at the end of the day, it’s nice to have computers seem “fun” again.
At least, that’s my perspective.
Whatever you decide for your laptop, I’m a proponent of a barebones off-site setup if you’re trying for 3-2-1 backup or similar.
I use a raspberry pi 3 with a single HD (ZFS) retaining some number of daily/weekly/monthly snapshots. Daily rsync, everything over WireGuard+VPS (TailScale would work too).
Temba, his hand throwing horns 🤘
Same — rsync to a pi 3 with a (single) ZFS drive at family’s house. Retain some daily/weekly/monthly snapshots.
I have a (free) VPS with static IPv4 which is how I connect everything.
Both the VPS and the remote site have limited network speed (I think 50Mbps for VPS), so the initial sync was done sneakernet (well…“airplane net”). Nightly rsync is no problem bandwidth-wise, and is mostly just any new videos I’ve uploaded to my local Immich instance.
Look, if you don’t want to listen to some random dude who thinks reading is cool, fair enough. But if that random dude also runs level three diagnostics on the warp core and can swap polarity on the main deflector dish with one hand tied behind his back? Yeah…you should probably pay attention.
I’ve been pleasantly surprised by vegan blue cheese dressings, but blue cheese itself…yeah, it’s got a long ways to go.
I just wish we’d have neither inflation nor deflation.
Some tech has followed this pattern. For example: entry level Mac laptop in ~2000 was the iBook, priced at $1599 ($3k+ in today’s dollars). The current entry level Mac laptop (M4 Air) starts at $999 — cheaper in absolute dollars, and way cheaper in relative dollars.
(Macs are just an example since Apple doesn’t have a very extensive product list, so there’s only one “entry level” laptop to choose from. And yes it’s fair to ask if the relative specs have just gotten worse, but I think this is also the opposite — the iBook was iirc criticized as being underpowered, whereas the M4 Air is afaik well regarded.)
Missed opportunity to replace “dozen” with 11 ;)
My comment from another thread: https://startrek.website/comment/16491624
tl;dr: tiny production, would be astonished if they got $6k out of it, and that’s not counting time, props, transportation, etc.
I think a lot of companies view their free plan as recruiting/advertising — if you use TailScale personally and have a great experience then you’ll bring in business by advocating for it at work.
Of course it could go either way, and I don’t rely on TailScale (it’s my “backup” VPN to my home network)… we’ll see, I guess.
