Honestly I just want a sync solution I can host on my NAS that the mobile app can still access, which unfortunately isn't something the app natively supports, and more or less all of the current community solutions come with one caveat or another ( like the otherwise lovely git solution having issues on iOS clients, for example )
You can't host the sync server on your NAS, but you can definitely synchronize your notes to your NAS, which means you still have them available in case your desktop goes down and your smartphone breaks or is lost or something.
That's not the same, because it's gradual, as opposed to a beep / notification.
When things change gradually, I tend to ignore the change.
To put it in a different context, I've had the fadeout brush heads for years, but I had to get in the habit of changing my brush head when I went in for a dental cleaning because otherwise, I'd just keep using it forever.
Oh, I used this and the performance and deduplication surprised me greatly in ReFS. I was using it as a place to store backups of my systems. The on disk vs the file size was so great that I had to rethink my offsite storage solutions. There was a recent article on here from a researcher at Microsoft on file size and deduplication.
Deduplication is awesome, it's really unfortunate how dangerous it is with things available on Linux. I've had ZFS corrupt itself twice and not after disabling it, on the same hardware. And btrfs died on me once - I'm not 100% sure it's exactly due to that, but there's a limit how much I'm willing to spend time copying terabytes.
[I'm not sure I understood your question. I hope this helps.]
The gravitational waves travel also at the speed of light. They will reach first the point of the Earth that is closest to the event first. And then travel and reach the oposite point like 40ms later. The Earth is almost almost almost transparent, so the signal reaches all the Earth, but with a different small delay.
This might be a stupid question but to me it's hard to grasp that they travel at a "speed" when they are themselves distortions of time/space. Does it always make sense to say they move at the speed of light or only for say small amplitude waves where we can do some quasi-special-relativity trick?
Essentially one fixes some background metric that does not have the dynamical aspects of the inspiralling binary. Those dynamical aspects are then applied as perturbations of the background metric. When one then slices the 4-dimensional static background into 3 spacelike dimensions along some timeline, the departures from the background (the perturbations) then propagate like massless waves.
Masslessness (and no refraction, birefringence, etc.) is why the wave propagates at "c".
Light propagates as massless waves too, which is why the speed of light is "c". The constant is geometrical in origin (it's because our spacetime is 4-dimensional, with one dimension of time: gory details at <https://en.wikipedia.org/wiki/Causal_structure>, particularly the "Curves" subsection of the Introduction), although "c" was discovered by studying the speed of light.
Linearized gravity is a good approximation but not fully general. It breaks down in extremes of compactness, and so one resorts to numerical relativity (on supercomputers) for understanding the final parts of inspirals of merging black hole and neutron star binaries (both species are compact, and in the final inspiral each binary partner orbits within the "compactnes-really-matters" region of the other).
Pp-wave spacetimes (pp = plane-fronted and parallel) can with suitable separations can have arbitrary constant wave amplitudes. Such spacetimes admit a Killing vector field letting us have a sensible way of measuring the propagation speed of the wave. At any point where it is measured, the propagation is lightlike.
Parts of a spacetime around an equal-mass circular-orbit binary will be reasonably approximated by a pp-wave spacetime (edge-on, not too close to the sources, and over a duration where their orbit is negligibly contracting).
Nah, D1 is in a different league.[1] One key feature of D1 is having free read replicas around the globe. That's CF's DNA and I expect this to happen this or latest Q1/24, and again, for free (so, without any surcharge). Re storage: You get ofc more than 1GB on the paid plan.
Neon doesn't have read replicas and even if they already work on it, I wouldn't expect it before 2025 if at all and never at CF's pricing (Neon still charges for egress).
[1] I would compare D1 rather to Turso or LiteFS from Fly or PlanetScale with many read-replicas
