I was listening to a radio show from the 30s a while back, and it was pretty clear that people were concerned, but their main historian thought that basically it'd blow over, and nobody would support hitler. Also they had a musician who refused to play any wagner. The show was clearly trying to be apolitical, but even in that context some of them were clearly objecting on principle.

I mean, you can say that about any signifier. The advantage of symbolic logic is you can draw connections between matching some set of constraints and having a certain trait. Checking in with reality is necessary, but that's true of many other signifiers, like... words.

mostly skimmed, but yeah, you have to be very careful when applying set constructs to reality. Especially since even their substitutions violate set theory. At least in math there's a big difference between "nothing" and "the empty set", and if you treat U as "everything" you're going to get into trouble.

I also like the idea of how you'd end up phrasing some equations. Even demorgan's would end up being something like
"everything except things which are A or B = everything that is both everything except A and everything except B"

One thing that's surprised me with covid-19 is it taught me that a ton people just haven't learned much about the AIDS outbreak in USA. Especially non-LGBT people.

Finally got models rendering in my relativity simulation! Other work keeps intruding, and I still want to clean up the code, but it's getting easier and easier to just throw together visualizations. Next couple steps are probably code cleanup, first person view, and adding reticles indicating where tiny objects like the planets are, and their distortions.

One of the tricky parts I ran into recently was actually just taking video of it in action, cutting the video, and then putting it up somewhere.

So far it's a bit hard to come up with visualizations that are intuitive to people with no background in what's going on, but I think a first person view will help there, and good transitions from intuitive views to lesser-known ones like worldlines.

I don't know what you mean by this. If you were able to extract more energy than you put in from the unruh effect that'd mean the engine causing the initial acceleration was doing something impossible, not that the unruh effect was the key.

The quantized inertia thing looks to be an attempt to explain why you need to add energy to maintain acceleration, and it's not widely accepted.

I assume the "ultradense rotating core" you're kinda just throwing things together hoping to cheat physics. "Ultradense" wouldn't help, and "rotating" wouldn't help. If you're trying to do something using black holes, remember you have to keep putting stuff into a black hole to keep it running.

That said, I don't see anything violating physics in that video. Everything's moving really slow, so it's not the velocity that's the problem, and it's not exactly a clear picture, so there's no indication that it's not expelling solid fuel. Even if it WERE clear, it could expel any number of things that wouldn't show up visually or on radar. There's no indication of what it's made of, so even if it isn't expelling fuel it could still be something not made of matter.

From what I can tell that's exactly the kind of thing I was thinking of. It looks like Receiver is a prototype made in a week selling for \$5, and Receiver 2 is a 1 year development game going for \$20. Obviously specific numbers aren't important, just the concept of "first one's short, second one's long" and "first one's cheap, second one's normal price"

Spend a short time creating a game with a very limited scope. In game jams they tend to spend a few days on the product with a fixed release date, but I could see making your prototype take a couple weeks to a month, and throw it up for a few dollars on itch.io (or even steam these days). If the game doesn't do well, ditch the concept and make another one. If it catches on, then do a full development cycle on it.

It seems like the more traditional way is to make the prototype free, but I guess there's no real reason it HAS to be.

It seems like Receiver did this, as others mentioned.

It really depends on what you mean. I don't like the modern eternal beta with constant feature creep. If you're suggesting a "prototype" pre-alpha which is eventually "fleshed out" into a full game, then no. That sounds terrible. If you mean a paid game-jam style prototype, which then gets remade into a full game with its own development cycle, then that's probably a good idea. See Celeste for a somewhat recent success of the two releases thing.

I don't see why you would revoke the prototype though. If someone wants to play the prototype, let 'em.

I grew up in the age of A/S/L, so I got pretty used to everyone knowing those three. Seems like that would be considered crazy these days. I think revealing those usually led to more good interactions than bad ones in chatrooms. When I was around 14 it would dissuade drunk 40 year old women hitting on me, which was handy.

These days people don't ask, so I don't share unless it's directly relevant. Also I tend to be on slower media now. On tildes people will be reading long posts, so they'll see (and potentially judge) your age instantly. When I was young in IRL conversations I definitely noticed I was taken less seriously due to age, and even worked explicitly on lowering my voice so I could be taken more seriously when discussing stuff I actually knew about (actually still helps as an adult). Also now stuff is more permanent, so I'd imagine you'd get more creepy people seeking you out. So if I were young these days I'd probably hide my age in public.

Most women I know are pretty sexual, and are aware of it. Saying you're not into sex this early in a relationship would be completely understandable. If they've been in other relationships it's likely it's something they've encountered before. If they take it as a slight that you're not looking for sex that early, I'd probably take it as a red flag. If they don't take "no" for an answer, or try to pressure you, that's not a relationship you want to be in.

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.

Whoa, I remember that! I was super interested in VRML, and enjoyed looking at what they'd done with it. It was really cool to poke around and see how it was done. I don't think I ever did any of the community stuff, but it was definitely fun looking at the tech.
