  • [Web] [mid to late 2010s] Game from the agar.io era
    Hey, the game I am looking for was from when agar.io was popular. It was a singleplayer game where your cursor was a little dot. Bigger dots would fly into the screen from every side and you had to avoid them, as if you touched them with your small dot you would die. However, there were also some smaller dots coming that you could touch to get bigger. So you basically had to eat the smaller dots and avoid the... Source: 7 months ago
  • Multiplayer Help -- Hosting Multiple Games/Rooms
    Question: Is it possible to use the "High-Level Multiplayer API" to implement different "game rooms" from the same server? For example, in the case of agar.io, you can create different game rooms that can be joined by you're friends with a code. From what I can tell, when a client connects to the server using MultiplayerPeer, the server acts as another peer in the game, so I can't tell if it's possible to let that... Source: 9 months ago
  • .io Game Server Infrastructure
    So, my question is: What kind of servers do IO games like agar.io, diep.io or slither.io typically use? (I'm not talking about the ones who are faking multiplayer of course. Source: 10 months ago
  • how could we get teamers and hackers to play fair again?
    Its annoying that you as a normal player don't has a chance anymore. What can we do so agar.io will be as fun as back in the day when it was 2016 and there was no teaming? Source: 12 months ago
  • help finding an io game
    I remember it being an agar.io style game, but you were blocks and might have become littler blocks when you died. I think the name started with a k, or one of the skins had the letter k in it. I remember playing it 2-3 years ago. Source: about 1 year ago

  • ESASky
    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 / 14 days ago
  • My 9 year old nephews drawing of stars
    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 1 year ago

    Celestia was something I played with before. Pretty interesting. Source: over 1 year ago

  • Tips to visualize Apollo 17 trajectory
    I'm looking for data and software to visualize the Apollo 17 trajectory (especially the "powered descent", lunar rendezvous and entry). I'm thinking of using celestia. I'm look for a data tables as well (time stamp, position for each part of the stack). Any tips are appreciated. Source: over 1 year ago
