#242What a fantastic visualization. I've read through the Bobiverse series twice at this point and remember all these different star systems from the books (Epsilon Eridani,Tau Ceti, Tau Ceti, etc,) but I've never seen a visualization of where they're located and didn't realize just how much I've wanted something like this until I saw it.

#243Very Cool! What was the hardest part creating it?

#244Earlier quoted context omitted.
It does, it helps to stop and smell the roses occasionally and remember how far we’ve come. My first proper computer (defined by programming on it) was a 3.5MHz single core processor with 48KB of RAM. My current one is 16C/32T that can boost to 5.7GHz and has 64GB of RAM. Considerably more than a million times the RAM and about a million times the processing power (if you factor clock speeds, core count, OOE, branch…
My pet realization: most of the power increase has been spent on graphics at an ever growing resolution, including in resolution not only the number of pixels, that's a squared number, but also color depth and FPS. Dealing with graphics has shadowed how hugely powerful the modern computers are. We're noticing now because of AI.
For a general user I suspect that is true.
That said I think programmers do notice the performance outside of AI when they use software that surfaces how fast modern machines are which we do more than most.
I can remember when compiling a Linux kernel was “start it and go watch star gate” now I barely have time to boil the kettle for a cup of tea.

#245Hi there! This is Val, I made the star chart. There's a little "about" blurb you can open in a modal on the site, but I wanted to mention that this demo uses the amazing GAIA DR3 dataset from ESA. I have a Python script that renders all 1.8+ billion stars into custom images, which is what I used for the skybox. The star positions and colors all use the GAIA data (save for a few bright stars not in the set). The data…
I'm also looking to do some personal projects with the Gaia DR3 release! Do you have any general recommendations for working with/trimming down such a huge dataset (e.g. Python libraries that can help)?

#247Looks like the desktop game Homeworld. (One of my all-time favs.)

Cool! One question: what do the planes represent? I thought it was the galactic plane and planes parallel to it, but then I saw that the "band" of the galaxy is (almost?) perpendicular to it, which doesn't fit somehow? EDIT: TIL that the ecliptic plane of the Solar System is at an 60.2° angle to the galactic plane ( https://en.wikipedia.org/wiki/Galactic_plane#/media/File:Mot... ) - until now I somehow assumed that t…
Go outside on a dark night and look at the Milky Way: you'll see (at the right time of the year) that it's tilted at a large angle to the celestial equator. (There's also the fact that the Earth's axis is tilted relative to the Ecliptic, of course.)

#249On Vivaldi (a chromium-based browser), it just hangs at the initialization phase. I tried it on Firefox, and of course it comes right up.

Since you built it, I am curious about the scientific accuracy of the movie, book and while taking the information GAIA DR3. I wanted to assume at least the stars part is science, but I think, there is a lot of fiction in that setting. Is this map the reality of what we know as science, since it came from GAIA DR3 dataset? And, thank you very much. This is super cool and exciting. I wish such a one exists for Asimov'…
Not about the stars part or the map, but xenonite struck me as rather odd from a scientific standpoint. Apparently it's some organic chemical bonded--somehow--to xenon. But the mystery depended on the mass spectrometer Grace uses to analyze xenonite not being able to detect nuclei of atoms smaller than some atomic number (something like 20?). So he couldn't tell what it was made of, except for xenon. My initial assumption was that it had to do with one of the few xenon-based compounds we know about, XeF4 (xenon tetrafloride), but there must be more to it than that.
