    It's especially strange going from WHO recommendations to outright panic of friends. WHO doesn't even seem to recommend avoiding large gatherings if you're under 40. WHO just suggests washing your hands, skipping handshakes, coughing into your elbow, etc. The basics. The people I know are suggesting stocking up on a few weeks of food, canceling all events, and only working from home...

    The panic is really getting out of control.

    Working on a simulation of special relativity with some low accuracy general relativity stuff, hoping to turn it into edutainment giving people an intuitive feel for relativity. I've got the basics of the positions of each object, but currently each object uses its own internal timeframe to calculate how far to move in a frame, so you can end up with fast objects being too far ahead in time.

    What I'd like to do is have each object run until it hits the observer's "present" plane, with a restriction that nothing hits the future light cone of the observer, but I'm running all this on the graphics card, and detecting that would be tricky with how I currently have it running without killing performance.

    At least I got a bit of a confidence boost when I plotted the solar probe and watched the simulation send it right by venus.

    Personally I find quaternions pretty nice to work with, and don't really see much point in switching to rotors. The main problem I have implementationwise is debugging. I can easily tell that my xyzw quaternion is rotating around xyz by w. With rotors you need to remember to negate 2 of the components (and in the code as-written also swap 01 and 12).

    I'm pretty used to seeing in debug output stuff like
    x: (0, 0, 1, 1)
    rotation: (0.24, 0.49, 0.74, 0.39)

    It seems like this would be changed to
    rotation(-0.74, 0.49, -0.24, 0.39)

    Donkey Kong Country games were bad. They used "3D" in a way that just made the game harder to read, felt really "zoomed in" probably due to a wide sprite, kinda boring level layouts, repetitive enemies, etc.

    I feel like it got popular because it used some good looking 3D models for the time. I really didn't like 3D when I first played it, so I was biased against it, but I feel like looking back my criticisms still stand.

    I live in LA, and don't own a car. I tried driving in LA when I first arrived and it was just so miserable that I swore it off. Now I take public transit and it's not nearly as bad as people think. The trains are way better than buses, and run pretty frequently.

    I think the best improvement at the moment would be convincing LA people to give trains a try once during rush hour. Public opinion of people who haven't tried it seems to be a major obstacle. Maybe having occasional free days to make it easier to try. Maybe publicize some kind of rush-hour race between a car and a train. It'd be pretty easy to choose a route and time which would make the train way faster.

    As for how to improve the actual experience, the obvious things are ones the city is already doing. More locations served by trains, more frequent trains. Buses exist to go where trains don't, but they're pretty slow, so I think expanding the trains is a better solution. Bike lanes can also help, but they don't form a network, so you're always going to be sharing the road with some pretty oblivious cars (city's working on that too).

    One thing that seems like it would make buses and trains more efficient, but less usable would be to have more routes with fewer stops. If you're going long distance, you can end up with most of your time spent sitting at stops (the bus route home from work would require waiting for 33 stops).

    I'm car-free in LA. It's really way easier than people think. That said, I have full use of my legs. For wheelchairs I don't think I've seen anywhere worse. The sidewalks are frequently impassible to wheelchairs due to bad design or damage, and the scooters go from handy tools to additional sidewalk obstructions.

    Why not just replace like... 10% of parking spaces with dockless bike/scooter parking? Heck, for a bit more money you could add a bike rack and allow individual bikes to park too.

    The reason I'm using "in some sense" is because
    a) You can parametrize time however you want.
    b) We're seeing it now, so in some other sense "it's happening now". I'm guessing that sense is what's causing the misconception that the gravity wave will take 2.5 billion years to arrive.

    Gravity waves propagate at the speed of light. So if we can see the collision, we'll feel the gravity waves. In some sense the events happened 2.5 billion years ago.

    Jack Orlando is a homophobic, racist detective, and the hero of an adventure game. For some reason, when you bring up the action wheel, the cursor starts on a gun. Really makes it seem like Jack's first instinct is to shoot everyone he meets, which fits with the abhorrent character. The game's not worth playing, just a probably unintentional bit of gameplay storytelling.

    On spec compliant devices it's pretty easy to plug in the correct way around. The USB symbol is SUPPOSED to be on top. Unfortunately many devices are non-compliant, like blackberry putting the blackberry logo on top.

    It should really have a haptic indicator also, but once you know which way is "up" it's fairly easy to work with.
