You could go a long way by specifying the reflectiveness over the visible light spectrum and then do the same for light sources. That way, you could do GDR style truly monochrome sodium vapor lamps, which makes telling colors apart impossible.

To do neon colors, you would need some sort of frequency redirect in your texture data as in "this pixel absorbs 80% infrared, but reemits it as visible red". Then you could have black light light sources and cool poster textures as well.

I think doing textures in this format would take too much space, but doing a 256 color palette that way might be fine.


“ultraviolet”, not infrared. IR to visible light would be upconversion.

https://en.wikipedia.org/wiki/Photon_upconversion


Oh, interesting. So do all neon colors reflect ultraviolet as visible light? Would a neon color that reflects IR as visible be possible? Or is it already figured out, but more expensive than UV neon paint?


Keyword recalling from a word in GP comment: photon downconversion is relatively easy and used widely, used in LEDs already, but upconversion require more exotic compounds and their efficiency is magnitude worse. Possible but not yet useful. It's certainly not like just using Lithium instead of Neon.


Neat! If you don't have a PostgreSQL DB ready, you can also compile Commodore 64 Basic for you HP 15-C calculator instead: https://forum.swissmicros.com/viewtopic.php?f=23&t=2194&p=11...


They probably meant "Boomer" in the colloquial sense of "somewhat old person" like how "Boomer Shooters" are for GenX and older Millenials.


Thanks! I didn't know that. That's... really unfortunate that the slang has gone that direction.


Could somebody explain the Coral Pixel font? It makes no sense to me, given that the whole point of sub pixels was to look sharp without looking colorful. It only ever looked like that when you took a screenshot and then zoomed in, which seems extremely niche.


All technology, no matter how undesirable it once felt, eventually becomes nostalgic for somebody.


> the whole point of sub pixels was to look sharp without looking colorful

That was the point, but it never worked: in practice, at least for me, text was smeary and colorful in that era. I wouldn’t want to use Coral Pixel, but I can imagine someone else being nostalgic for it.


Same here. The MS-Windows boxes at college had lots of coral reef around the glyph edges


Depends on the DPI of your monitor and your glasses prescription.


Oooh, you mean people turned on sub pixel rendering while running their screen at a non-native resolution and thus got these colors all the time? Yeah, I guess that could cause nostalgia.

Thanks!


I think it depends on the country. In Germany, everything you write is automatically copyrighted, unless you explicitly waive it. In the US, it's the other way around, you have to explicitly state that you want copyright (can somebody confirm this?).

I'm not a lawyer, but I guess a German posting on Hacker News effectively waives their copyright by sending their comment to the US, where an US company then publishes the comment on a US server.


It depends on the language and/or used libraries. E.g. in Go, the problem does not exist, because it uses UTF-32; Rust uses UTF-8, but it makes sure that you can't cut a string between bytes that belong to the same character.

Fun Java/macos quirk: macos normalizes file names, so you can't have two files called ü in the same directory by writing ü as a single character and as composing characters. But unfortunately, this only happens on write, not on read, so if you type an ü on a German keyboard (produces a single character) into the Java source code file when writing a file name, the file will be saved with the decomposed name instead, but when trying to open the file, it will not be found when trying to open it with the single character name.


The way I remember it was that replay playback would only break if you played a replay with a different game version than it was recorded with.


There was definitely sync bugs with replays at various points.

There was even desync bugs even in live multiplayer games; there was detection that it desynced which would end the game, which in turn meant exploits that would intentionally cause a desync (which would typically involve cancelled zerg buildings for some reason).


or, if you are replaying a single-player game that you saved+loaded (i.e. the replay only worked if the full game happened in one go without any loads).


They don't see the letters, so how could they possibly succeed at that? It's like asking a human how many infrared flowers they see.


I'm pointing out that they don't 'think' or 'reason' like humans, they're very impressive, but I don't think they've reached the bar for thinking yet, as simple logic puzzles or puzzles like this prove (until the LLM authors take note and add special workarounds for those particular use-cases).

I believe most LLMS no longer fail at this, because they've been given the tools to do so (for example use python under the hood to count letters), but it's an important observation because it shows us that they don't think like us.


Is there some philosophical/ethics work done on the question which fictional crimes, taboo breaks or unethical behavior are okay and which aren't? Iirc Japan takes the extreme position of legalizing all fictional wrongdoings, whereas the west is okay with fictional violence (e.g. murder mysteries), but not okay with some other things. Where to draw the line?


Isn't it illegal to show the pubic region in Japanese porn??


QR codes store bits, arranged into bytes (A byte is the shape of a 3x3 square with one corner missing), so how more traditional can it get?
