Incredible work! My son really had a blast scrolling around and exploring last night. Did you take any inspiration from Celestia (https://celestiaproject.space)? It's been over 15 years since I last really used it (and starts with defaults not geared towards visualizing just our local solar system) but seems to have a lot of the features others have suggested. Might be useful to poke around and see how they solved... - Source: Hacker News / over 1 year ago
An honorable mention: https://celestiaproject.space This but in 3D and adjustable for any date. - Source: Hacker News / about 2 years ago
Pretty much everything beyond our solar system is essentially fixed on a human timescale. Over 2000 years, a typical star will move about half a degree. That's the width of the moon in the sky. There are of course notable exceptions like Barnard's Star, whose movement is pretty obvious on photographs taken over several decades. If you want to explore how space changes over time, I recommend you look into... - Source: Hacker News / about 2 years ago
I think Celestia could be a good one. I also thought about SpaceEngine, but AFAIK it was kind of terrible at generating realistic planetary systems, among other things (pricey, huge, etc.). Source: over 3 years ago
Celestia was something I played with before. Pretty interesting. Source: over 3 years ago
Let's hope this is going to help me solve some more Project Euler [1] problems! [1] https://projecteuler.net/. - Source: Hacker News / about 2 months ago
Https://projecteuler.net/ for "Thinker" brain food. (it still has the issue of not being a pragmatic use of time, but there are plenty interesting enough questions which it at least helps). - Source: Hacker News / 5 months ago
I have a Project Euler (https://projecteuler.net/) account. Though I do not register at all on the leader board I will sometimes work obsessively on a problem just to make one of the level icons light up for me. There is not really competition just a tiny reward. - Source: Hacker News / 7 months ago
I do hobby programing. It is sometimes to create something (supposedly) useful. Lately though it is more discovery and a little math like. I enjoy Project Euler (https://projecteuler.net/. Recently I have been playing with superpermutations (https://projecteuler.net/) and pencil and paper is useful but filling lots of paper with lots of numbers is not that fun. - Source: Hacker News / over 1 year ago
As pointed out in a sibling comment, it appears that quote only shows up if you're logged in, but assuming you have an account and are logged in, it's on the homepage (https://projecteuler.net/), second paragraph under the following heading: > I learned so much solving problem XXX, so is it okay to publish my solution elsewhere? > It appears that you have answered your own question. There is nothing quite like... - Source: Hacker News / over 1 year ago
