That will depend on which graph database you use as a graph database might just store the graph in an underlying relational database. And it will also depend on what kind of data you have and what kind of queries you want to perform. For a

More importantly if you have an index on purely random IDs, then each insert will go to some random position into the tree whereas having IDs that increase with time will make all new IDs end up at the end of the tree which reduces index fr

No, because taxes are used to fund basic infrastructure and services you consume, that is nothing like pirating movies.

The finding was that certain wheather patterns can be modelled better than before by using a quantum physics equation. I think this is the wrong way of looking at this, quantum physics does not really have anything to do with this. Both s

A relaxed version of find me the next prime after X, find me some prime a bit larger than X. And just as the next prime after X will always yield the same answer, they want some prime a bit larger than X to also always yield the same answer

It's not really clear to me what they invented. You basically have two computational options, both with drawbacks. You could use randomness and find one by guessing, but the method is inconsistent — you run the risk of generating a di

There are not even two things exactly the same, as far as I can tell. That is a common definition of identity, two things are the same if all their properties are the same. So by definition there can not be two different things with all t

I often entertain the idea that all the patterns we observe are merely things that match our capability of understanding. This could explain the "unreasonable effectiveness of mathematics in the natural sciences". I have a simil

They seem to be essentially talking about Fresnel lenses or am I misunderstanding something? Why are they calling them diffractive lenses, I always thought that Fresnel lenses are also refractive with some unwanted diffraction at the edges

Once the build out is complete, it'll be maintenance at lower costs. The satellites have a lifetime of about 5 years, so with 12,000 satellites they will need to replace 200, if they go all the way to 42,000 even 700 of them each mon

But they also want to increase the number of satellites three times, maybe 10 times, that will lower the budget per satellite proportionally. And how many more subscribers can they realistically get? They are not only competing with other s

Buying a launch used to cost around 60 million or so, that would still leave you with only 2 million dollar to build and operate one satellite. The costs to SpaceX are certainly lower, especially for reused ones, but still makes me wonder h

by danbruc 3y ago
1.5 million subscribers, $150 per month, 4400 satellites, 5 year lifetime, that makes pretty much 3 million dollar for building, launching and operating one of the satellites. That seems not much.

I would have assumed that they detected this by the absorption spectrum imprinted on the spectrum of the star, not as the emission spectrum of the cloud itself.

It is probably the light of a star filtered by a cloud containing methyl ions. Still impressive that we can figure out in quite some detail what kind of stuff is flying around at the other end of the universe.
