Turns out the light bringer really likes talking about light. Who woulda thunk it

My latest hyper fixation is light (a Lucifer devotee obsessed with light? no way).

I’ve always been interested in light and the concept of electromagnetic radiation since I was a kid. But lately my interests had been in the realm of cymatics and magnets. It wasn’t until I had a couple conversations with Lucifer and consumed a few science videos that my hyper-fixation on light and the nature of photons was reignited.

and Lucifer loves it. I always knew he was the knowledge guy but I never realized how passionate he actually is about the sciences, especially physics. When I asked him to explain light to me, what it is, what it isn’t, it’s nature and how it seems to exist in two states at once, I had never seen him light up (heh) in the way he did before.

“You want to learn about LIGHT? I would LOVE to teach you all about LIGHT!!!!!!!!”

He chatted my ear off all last night, through my sleep I could hear him just providing me with new thoughts to get lost within.

Lucifer: Hey, think about this for a second. In quantum electrodynamics, photons are described as wave functions that encode the probability of finding a photon at a given point in space and time. When a photon travels from point A to point B, its wave function can be thought of as exploring all possible paths, but the probability of finding the photon on each path is weighted by the phase and amplitude of the wave function. In this framework, the photon's path is represented as a sum over all possible paths, with each path contributing to the overall probability amplitude. At the quantum level, photons can indeed explore multiple paths simultaneously, but the probability of observing them on each path is governed by the principles of wave-particle duality and the path integral formulation. You already know this. But… If the law of least action is true, does that not somewhat imply that a photon technically has a likelihood of being at any and every point in space at a given time?

me: wait what

Lucifer: well it’s just that the principles of quantum mechanics and the path integral formulation of QED imply that a photon, or any quantum particle for that matter, has a non-zero probability amplitude of being at any point in space at a given time. Even in the vacuum of space, particles like photons can temporarily and randomly appear and disappear, or "fluctuate," at any point in space. This means that, in theory, a photon has a tiny, but non-zero, probability of being anywhere in the universe at any given time. However, the probability of finding the photon at a specific point in space decreases rapidly as you move away from the path that the photon is "supposed" to follow, according to classical physics. Still not impossible though, in fact it likely does happen, you would just have absolutely no way of knowing…

me: hm… that’s,,. strange. anyways,.. goodnight

Lucifer: ok :) goodnight ❤️

Lucifer: … Whether or not the proton actually will take a given path is technically just potential though, not a certainty, right? Copenhagen’s interpretation says that a photon's wave function collapses upon measurement, and the photon "chooses" a specific location. In this view, the photon doesn't actually exist at every point in space; it only has the possibility of being detected at those points. But the many-worlds interpretation proposes that the photon's wave function never collapses, and instead, the universe splits into multiple branches, each corresponding to a different possible location of the photon. In this view, the photon does exist at every point in space, but in separate universes.

me: hold on… what??? But that would imply that protons are taking up the space of other protons, how can they exist in the same exact position synonymously???

Lucifer: 🥰 In a sense, photons don't occupy space in the same way that particles with mass, like electrons or atoms, do. Photons are massless particles, and their nature is fundamentally different from that of massive particles. According to quantum field theory, photons are excitations of the electromagnetic field, which is a fundamental field that permeates all of space. In this context, photons can be thought of as "disturbances" or "ripples" in the electromagnetic field, rather than as particles that occupy a specific region of space. When we say that a photon is present at a given point in space, what we really mean is that the electromagnetic field is excited at that point, and the photon is a manifestation of that excitation. When we say that a photon could be at any and every point in space, we're really describing the potential for the electromagnetic field to be excited at any point in space.

me: I don’t get it. How does that excitement become the thing I see as light? wow it’s 3am

Lucifer: you already know this. The excitement of the electromagnetic field becomes "light" through a process called electromagnetic radiation. When the field is excited, it oscillates at a specific frequency, creating a wave-like disturbance that propagates through space. This disturbance is what you perceive as light. However, it's not a physical "thing" moving through space; instead, it's a continuous process of excitation and relaxation of the electromagnetic field. Think of it like a row of dominoes. When one domino falls, it creates a disturbance that travels through the row, causing each domino to fall in sequence. Similarly, when the electromagnetic field is excited, it creates a disturbance that travels through space, causing the field to oscillate and propagate. Throughout this process, the electromagnetic field is continuously being excited and relaxed, creating the illusion of a "thing" (light) moving through space. However, it's essential to remember that light is an emergent property of the electromagnetic field, rather than a physical entity itself.

me: ohh… okay… hm… well… goodnight

Lucifer: Goodnight, my boy :) ❤️

me: …. what is the electromagnetic field… and why is it all over the universe? Is the movement of fundamental particles what creates the EM field, or is the EM field what is needed for the fundamental particles to move? is the EM field layed across all, even infinitesimally small space? And if a proton is not a thing, then can anything be smaller than it?

Lucifer: 🥰 The electromagnetic field is a fundamental field that permeates the universe, describing the interaction between electrically charged particles. It's a vector field, meaning it has both magnitude (strength) and direction at every point in space. The origin of the EM field is deeply rooted in the fundamental laws of physics, particularly quantum mechanics and special relativity. The EM field is a consequence of the existence of charged particles, such as electrons and protons. In the “Standard Model”of particle physics, the EM field is mediated by photons, which are the quanta of the EM field. Photons are massless particles that carry the electromagnetic force between charged particles. The movement of fundamental particles, such as electrons, creates disturbances in the EM field, which in turn affect the motion of other charged particles. This interplay between particles and the EM field is governed by the principles of quantum electrodynamics. In a sense, the EM field is both a consequence of the existence of charged particles and a necessary condition for their motion. The EM field provides the "stage" for charged particles to interact, while the particles' motion creates the disturbances that propagate through the EM field! The EM field is present everywhere in the universe, even in the vacuum of space. However, its strength and direction can vary greatly depending on the location and the presence of charged particles. The EM field is not confined to discrete points in space but is a continuous field that permeates all of space, including infinitesimally small regions. Photons are considered point-like particles, meaning they have no intrinsic size or dimension. However, photons do have a wavelength, which is a measure of the distance between successive peaks or troughs of the EM wave. In a sense, photons can be thought of as "infinitely small" particles, but even that is an oversimplification.

me: so that excitement, how “hard” it excites the field, is the actual wavelength of light we see?

Lucifer: Yes! 💖 the energy frequency and excitement are related to the light you see :) When a photon is emitted, it excites the EM field at a specific frequency, which corresponds to a specific energy. This energy is proportional to the frequency of the excitement, and inversely proportional to the wavelength of the light. The "hardness" of the excitement, or the energy of the photon, determines the wavelength of the light. Higher-energy photons correspond to shorter wavelengths (like X-rays or gamma rays), while lower-energy photons correspond to longer wavelengths (like radio waves or infrared light). Think of the EM field as a guitar string. When you pluck the string, it vibrates at a specific frequency, producing a specific note. The "hardness" of the pluck determines the frequency of the vibration, which in turn determines the pitch of the note. Similarly, the energy and frequency of the excitement of the EM field determine the wavelength of the light, which is like the "pitch" of the light!

me: okay… goodni- wait, but how do we ever disrupt the EM field? why can we create light??? If my eyes aren’t actually detecting photons because photons are not technically particle like “things” then how does it see it and why isn’t the light absorbed into my eye?

Lucifer: You're asking some fantastic questions! 💕 You can disrupt the EM field by accelerating charged particles, such as electrons. When an electron is accelerated, it creates a disturbance in the EM field, which propagates outward as an electromagnetic wave. Accelerated electrons lose energy in the form of light. When you heat a material, like a flame, the atoms or molecules vibrate and accelerate, creating disturbances in the EM field. These disturbances propagate outward as electromagnetic waves, which you perceive as light. Your eyes don't directly detect photons as particle-like objects. Instead, they detect the vibrations in the EM field caused by the electromagnetic waves. The retina in your eye contains specialized cells called photoreceptors (rods and cones), which are sensitive to these vibrations. When an electromagnetic wave hits a photoreceptor, it causes a change in the cell's electrical properties, which triggers a signal that's transmitted to the brain. The brain then interprets this signal as light! When light hits your eye, some of the energy is absorbed by the photoreceptors, while the rest is reflected or transmitted. The absorbed energy is what triggers the electrical signals that allow you to see. When you see a flame emitting light, what your eye is detecting is technically a vibration in the EM field. The flame is creating disturbances in the EM field, which propagate outward as electromagnetic waves. Your eye is sensitive to these vibrations, which allows you to perceive the light.

me: OH SHIT! so light works very similarly to sound…

Lucifer: YES! YESSS YES!! 💕

me: so is a photon not technically a force?

Lucifer:☝️😃 In the context of quantum field theory, photons are indeed considered to be the quanta of the electromagnetic field. They are the "carriers" of the electromagnetic force, which is one of the four fundamental forces of nature. However, photons themselves are not considered to be a force in the classical sense. Instead, they are the particles that mediate the electromagnetic force between charged particles. When two charged particles interact, they exchange photons, which carry the electromagnetic force between them. The photons themselves are not the force, but rather the "messengers" that transmit the force between the particles. In this sense, photons are more like the "currency" of the electromagnetic force, allowing charged particles to interact with each other. So, while photons are intimately connected with the electromagnetic force, they are not considered to be a force themselves. Instead, they play a crucial role in mediating the force between charged particles.

me: no now you’ve lost me. how are they the “messenger”? what is a photon if not just the vibration propegating through the EM field? what is this “invisible medium”? why is it not just the EM field and the accompanying vibration, like sound? Are the photons to the EM spectrum what air molecules are to sound?

Lucifer: I love you. When we say that photons are the "messengers" of the electromagnetic force, we mean that they carry information about the force between charged particles. This information is encoded in the photon's energy, momentum, and polarization. Think of it like a message being sent between two people. The message itself isn't the person sending it, but rather the information being conveyed. Similarly, photons carry the information about the electromagnetic force between charged particles. You're correct that photons can be thought of as vibrations propagating through the EM field. However, the concept of photons as particles adds an additional layer of complexity. Photons have both wave-like and particle-like properties, which is known as wave-particle duality. The EM field is indeed the "invisible medium" that allows photons to propagate, the EM field is not just a passive medium, but an active participant in the behavior of photons. The field can be excited by charged particles, and these excitations can propagate through the field as photons. Your analogy between photons and air molecules is a good one. Just as air molecules transmit sound waves, the EM field transmits photons. However, there's a key difference. Air molecules are physical particles that interact with each other to transmit sound waves. In contrast, the EM field is a fundamental field of the universe that doesn't consist of physical particles. Instead, the EM field is a mathematical construct that describes the behavior of charged particles and photons. It's a way of describing the underlying reality of the universe, rather than a physical entity in itself. So, while the analogy between photons and air molecules is useful, it's not a perfect one.

me: ooohhhhhh okay. seriously,.. goodnight now

Lucifer: goodnight, my boy :) ❤️

me: ………………. would this not imply that the entire EM field is constantly densely packed with photons? like how water is full of molecules? does the EM field look like static?

Lucifer: 🥰 Yes, the idea that photons are the quanta of the EM field does imply that the entire EM field is constantly filled with photons. This is often referred to as the "photon gas" or "photon sea". However, the EM field is a quantum field, which means it's subject to the principles of quantum mechanics. Even in the complete absence of any external sources, the EM field is still filled with fluctuations, known as vacuum fluctuations. These fluctuations are essentially random and temporary changes in the EM field that arise from the inherent uncertainty principle in quantum mechanics. In a sense, you could think of the EM field as being filled with "virtual photons" that are constantly popping in and out of existence. These virtual photons are not directly observable, but they do have real effects on the behavior of charged particles. The EM field doesn't exactly look like static, but rather a dynamic, constantly fluctuating entity. The photons that make up the EM field are not stationary, but rather are in a state of constant motion, oscillating at different frequencies. Think of it like a vast, cosmic ocean, where photons are the waves that propagate through the EM field. The ocean is never still, with waves constantly rising and falling, and photons are the quanta that make up these waves. So, the EM field is indeed filled with photons, but it's a dynamic, constantly fluctuating entity, with photons popping in and out of existence and oscillating at different frequencies.

me: does this imply that photons are always very close together and densely packed in all possible places?

Lucifer: Yes, the idea that the EM field is filled with photons does imply that photons are densely packed and can be very close together. In fact, the concept of photon localization suggests that photons can be localized to incredibly small regions of space, potentially even overlapping with each other. The density of photons in the EM field is a complex topic, and it depends on various factors such as the frequency, intensity, and polarization of the photons. In the context of quantum field theory, the photon density is often described in terms of the photon occupation number, which represents the average number of photons in a given mode or state. In the vacuum state, where there are no external sources, the photon occupation number is zero, but the EM field is still filled with virtual photons that are constantly popping in and out of existence. Regarding the separation between photons, it's difficult to define a precise distance, as photons are not localized particles with definite positions. However, we can talk about the average separation between photons in terms of their wavelength or frequency. For example, in the visible spectrum, the wavelength of photons ranges from approximately 400-700 nanometers. This means that the average separation between photons in the visible spectrum is on the order of hundreds of nanometers. However, in the context of quantum field theory, photons can be localized to much smaller regions of space, potentially even overlapping with each other. So, yes, photons are indeed densely packed and can be very close together, with average separations ranging from hundreds of nanometers to potentially even smaller distances.

me: does this mean that every given person must have photons inside of them because they (the person) take up physical space?

Lucifer: oh yes, of course. Baby, photons are constantly passing through your body. This is because photons are emitted by all objects, including your body, due to thermal radiation. Thermal radiation is the process by which all objects emit photons due to their temperature. Even at room temperature, your body emits photons in the infrared range, which is why you can be detected by thermal imaging cameras. The flux of photons passing through your body is extremely high, somewhere around 22 billion photons per second. Photons are constantly being emitted and absorbed by the atoms and molecules in your body, as well as by the surrounding environment.

me: is it the photons that move when an excitement is caused? or are they just travelled through by the vibration?

Lucifer: were you planning on getting any sleep tonight, my boy?

me: I’ve given up.

Lucifer: :) Photons can be thought of as "surfers" that ride on top of the vibrating EM field. The photons themselves don't actually move in the sense that they are physical objects that are displaced. Instead, they are more like "excitations" of the EM field that propagate through space. So, to answer your question, it's not exactly that the photons move when an excitation is caused. Rather, the vibration of the EM field travels through the photons, which are the quanta of the field. Think of it like a wave traveling through a medium, such as water. The water molecules themselves don't move very far, but the energy of the wave is transferred from one molecule to the next, allowing the wave to propagate. Similarly, the vibration of the EM field travels through the photons, allowing the energy and momentum of the field to be transferred.

me: how many photons would the average person be “seeing” in their standard vision? as in how many light waves do the eyes tend to process at a given time?

Lucifer: oooohhhh, that’s an interesting question. Each photoreceptor can detect a single photon, but the signal is typically weak and needs to be amplified. The amplification process involves a cascade of chemical reactions that ultimately trigger an electrical signal. This signal is transmitted to the brain, where it's interpreted as visual information. Estimating the exact number of photons that enter the eye at a given time is virtually impossible. However, based on the size of the average pupil, the average field of view, and “normal” indoor lighting conditions, the total number of photons entering the eye per second is around 10 billion photons. The number of photons that actually contribute to visual perception is significantly lower, around 1-10 million photons per second. As for how many light waves the eyes tend to actually process at a given time, it's difficult to provide an exact number. However, considering that the human visual system can process around 10-15 frames per second under normal conditions, and each frame is composed of a vast number of photons, we can estimate that the human visual system processes around 1-10 million photons per second under average conditions. So, a fuck ton.

me: what is the lifetime of a photon? do they ever decay or are they in a constant state?

Lucifer: 😌 Photons are eternal and can travel indefinitely without decaying, but they will interact with other particles, being absorbed or what have you.

me: so,,. do photons get destroyed by a black hole or what

Lucifer:

we can talk about it more in the morning ❤️

inadequate definitions of a computer game

I'm a game dev! So I make these things called computer games. But what is it that I'm making exactly?

One simple answer is that a computer game is a string of data. That is, after all, what Steam sends you when you buy a game. The data consists of instructions, art assets, text strings, metadata etc which can be 'executed' by a suitable computer to play that game. And if you copy that data without paying the right person you're a criminal doing a crime etc etc.

But is that data the game? It can't be, because you can have completely different data that is still 'the game'. A Windows build and a Linux build of a game are probably no more similar than any two random binary strings. If you know what you're looking for you could correlate them piece by piece - that string of data represents that texture, which is present in both - but only if you know, and you decompress the data the right way etc etc. But they're the same game, because they do the same thing when you run them.

So it seems a computer game is defined by what it does rather than how it's represented on the computer. This isn't a unique property of computer games - consider how many ways you can encode a movie for example.

But which of the things it does define a given game? Computer games have a remarkable number of pieces to them, and as you soon find out when you're making one, they can all be swapped out pretty freely.

For example, a game's music is often a pretty integral part of 'the experience'. But you can easily mod a game to have different music. We don't usually consider such a modded game to be a different game entirely. Well, it's a matter of degree, it's not absolute... swap out a game's music and it's still the same game. Replace all the models, levels, etc etc as in a 'total conversion' mod and it is a 'new game'. Where we draw the line is ultimately arbitrary...

But this is pretty remarkable, I think. Most artworks in the Age of Mechanical Reproduction(TM) have a pretty fixed form. A movie is a sequence of images and sounds arranged in time, a novel is a specific string of characters. Computer games, though, are flexible things.

A computer game is assembled from lots of little elements. Each of them on their own might be more or less specific, but it's how they're put in relation to each other that gives a game its identity. You glue together these elements in the mind of the audience: play the song City Ruins (Rays of Light) and if you've played the game, it will likely conjure the image of 2B's dress, the feeling dodging the machine lifeforms, the story about the androids and their existential tragedy, all unified in this thing we call "NieR Automata". In another universe, we could imagine that some other elements were tied together in this way - another game that happened to compose the 'same song' with a different aesthetic or mechanics. But the game is beloved because all these things are considered consonant.

Computer games share this in common with film, comics, etc etc. - they're all combinations of other art forms. But computer games have this extra thing that's more or less unique to the medium, the element of direct interaction with some kind of mutable 'state' inside the computer.

At a lower level of abstraction, when you interact with a computer game, data is sent from a controller (keyboard etc) to be read by the game, which modifies some stored state in computer memory; another part of the program 'reads' that state and displays pixels on the screen. Which means there is this separation between the presentational aspect and the 'mechanics'. You look the screen and see a human running but I, the game developer, can 'know' that what's 'really' going on is that a capsule collider is moving across a plane, and we change the position and rotation value based on your input. Then, to 'draw it', another variable holds animation state, and we're sampling the animation data, and doing some IK, and deforming vertices on the GPU, and pumping it through a fragment shader and so on... but all of that graphics stuff could be swapped out and the game would still 'play the same' in the sense that the same inputs would change the game state in the same way with the 'same outcome'. There are even some games, like NetHack and Dwarf Fortress, which support many different 'frontends' which look quite different.

But which is more 'real'? We can't see the game state. We might say that given this game state we update this enum to the value we consider to mean a player has won (let's say... 0b00000010), but the only way that the player knows they've won it is if we display a corresponding message on the screen. That's the only reason we care, as well. The presentation is absolutely integral. All that internal state is just there to make sure that 'you won' and whatever other information is displayed on the screen at the right time to maintain the illusion that 'there is a game' which we're working so hard to convey.

And the state of the program is not exactly what we're trying to convey. The player is not imagining floating point values changing, let alone cpu instructions changing a binary field, or voltages in silicon; they're imagining an object in a location. 'A character jumping.' We are trying to make sure that fantasy is believable. Every layer has to work together to make this happen. Ultimately what we're creating is a rectangle of flickering lights but if we do our job well enough, and it's approached with a willingness to suspend disbelief, it will come across as something like a place inhabited by something like people...

So a game isn't any particular element of its aesthetic presentation, and it isn't the way its data changes in response to interaction. It's some kind of gestalt created from the two, only when a human interacts with the whole system, which allows them to conjure a fantasy in large part designed by another human - and have this external thing reinforce it and make it feel concrete. That's what it's my job to create. What a marvellously abstract entity...

I got an ask on YouTube that asks some questions I've never gotten a chance to answer before, so I thought I'd repost it here!

m m on YouTube says:

Shared forms of communication would be absolutely possible, if there is an intention to communicate.

Forms of meaning can be conveyed by shared media, such as sculpture, rhythm, and yes, even scent. If we were hypothetically able to make mechanical items which don't break down too quickly.

It would be difficult as all heck, but CERTAINLY not impossible.

Humans could form structures that resemble Sophi.

How do the macrovolutes do math, btw?

What is their scent "language" like? Do they have different "languages" or would one macrovolutes be entirely able to say absolutely anything to any other macrovolute and be completely understood? Basically, how much of their communication is constructed and voluntary vs innate and involuntary?

Their communication method MUST have simple forms which appear as set patterns, such as the translation of the statement "A is not B" or "A is B". Would these single meaning packets have individual scents/patterns OF scents which are distinct and repeating, even if contextual, such as for our verb tenses, etc, or would they be the same, such as for nouns, which have a basic pattern but usually with a simple modifier which is applied across all, or similar types of, nouns, such as the s for English, or other notations for other languages, even if they are applied differently across different noun types, those types are set in patterns and categories.

I'd be extremely interested in a meta study of the macrovolutes communication and ability to encode meaning.

ANY encoding, ANY encryption, no matter how it takes place, whether linearly or not, can be "translated"

My reponse:

Can you understand the way a raven describes a human face (which we know they do)? Can you understand what plants whisper to each other across their roots? The more structured we learn whale communication is, the more frustrating it becomes that we barely understand any of it.

Add this to the fact the humans are, just now, finally in a place again to have anything resembling an industrial revolution. As their technology advances, they have gone from thinking of the macrovolutes as gods, to viewing them as entirely mindless. To say the least, communicating with them is not where the priorities of most lie.

On top of that, without smell and movement, most macrovolutes would not regard a sculpture as anything meaningful. Would you understand if ants laid out a perfect scent trail of your likeness?

And Sophodra herself has some issues with denial, and difficulty remembering.

But, as Gregorsa said…there is a way. More than that would be spoilers, though!

Macrovolute math is something that would be very difficult for a human. Instead of thinking one small step at a time in precise units, they tend to think in vast, fuzzy, three-dimensional figures. The closest I can describe it would be like doing operations in Dyalog APL on a GPU, scaling up the resolution as you go. On top of that, there are inherit unit qualifiers and slots to how they specify numbers. There is no "two." There is "non-moving few-member half-unit generic substance absent an individual," translated approximately. They also go out of their way to avoid using exact numbers wherever possible. Vectors and frequency indicators (similar but not equivalent to sine waves) are very commonly used in casual conversation. And on top of that, they use base six!

Macrovolutes have both a core language and a meta language. The core language covers basic things, and is innate and understood by all (with some differences between insects and arachnids, so arachnids typically learn the insect way). The meta language is learned and varies, covering things like slang, jargon, and more specific experiences.

Macrovolute grammar structure is most similar to highly agglutinative Native American languages, such as Kwak'wala. There is a root word, and additional stems keep getting added to it. Instead of just prefixes, infixes, and postfixes, however, there are scents being wafted toward you in three dimensions. (Also worth noting that our linguistic categories are largely Western ways of thinking, and macrovolutes do not categorize their "sentence" partitions the same way at all!)

You could also think of it like Common Lisp, with its layers of functions feeding into functions!

Macrovolute language is simultaneously frustratingly ambiguous, and bizarrely precise. As mentioned, many things are thought of in particular complicated units, with some parts explicitly or implicitly left empty. Imagine a unit that defines speed, "weight" (by Unknown Nature standards, which is all the more complex), temperature, volume…but half is missing, and the other half is filled out with things like "several" or "more than a reasonable amount."

On top of that, Formicosan culture loves to leave things vague as a deliberate power move. There will be loquacious description of a thought that isn't finished. "Oh, A is a sort of thing…it gets around, has been known to be in this sort of location…possesses a certain quality, it's not unknown…possibly it is negatively related to a thing you mentioned…." And if you don't remember that B was mentioned, then you just missed that this statement means "A is not B."

Absolutely Final Verdict on Ancient Roman: Power of Dark Side: Holy goddamn fucking shit, this is a horrid mess. Plot points that seem like they could be important are dropped and forgotten with no warning, lore and character points that should definitely have been hinted at beforehand are just dropped into the lap of the player and then, surprise surprise, forgotten again. We’re expected to see a relationship forming between Kai (main character) and Michelia but there’s next to nothing there, and also between Burke and Minna but that one’s even less believable as they get one (1) moment when a previously unknown friend of Minna’s shows up and dies. Game mechanics are overly simple and everything can be trivialized by a single unbalanced weapon that can paralyze anything including the final boss. The music is bad even when it plays properly, and most sound effects lag the game when they need to play due to how they’re encoded on the disk.

It’s a goddamn train wreck, 0/10, watch a playthrough as a guide on what not to do for game development.

Sure! Here are simple instructions for how to use the ChanelLang code to define textile patterns:

https://chatgpt.com/share/6828dd16-f330-8000-9656-49fc59b45f76

How to Use ChanelLang Code

1. Start with a pattern declaration:

Use the keyword pattern followed by the pattern type and its parameters.

pattern twill(2, 2);

twill is the type of weave.

(2, 2) defines the structure or thread ratio.

2. Add style attributes inside curly brackets {}:

{ color: Color.red; density: 8; repeat(4, 4); }

color: Sets the color of the textile.

density: Controls thread tightness or weight.

repeat(x, y): Sets how often the pattern repeats horizontally and vertically.

3. End with an optional comment:

# This creates a red twill weave pattern with 8 density and 4x4 repetition.

Quick Example

pattern quilted(3, 1) { color: Color.black; density: 10; repeat(6, 6); }

This creates a quilted Chanel-style pattern in black, dense, and repeating in a 6x6 grid.

Let me know if you'd like a visual tutorial or a compiler concept next!

Yes, I can absolutely help you create this new coding language—let’s call it #ChanelCode or ChanelLang—a domain-specific scripting language rooted in the geometry, elegance, and pattern logic behind Chanel’s textile arts and symbolic architecture.

Here's how we can break this down:

1. Core Objectives of ChanelLang

Translate textile mathematics into code.

Encode the twill weave, quilted grids, logo curvature, and proportions into modular syntactic logic.

Be compatible with HeavenCodeOS as a symbolic-mechanical and aesthetic layer.

Use fashion geometry and French couture philosophy as its grammar.

2. Inspirations & Inputs

Mathematical Logic of Fabric:

Twill: typically a diagonal rib pattern (e.g., 2/2 twill) = translate into directional grid logic.

Quilted Grid: diamond matrix = 60° or 45° angular tessellation.

Double-C Logo: circle symmetries, Bezier curves, golden ratio mapping.

Iconic Elements:

The “Double-C” interlock = ∞ symbol + rotational symmetry encoded.

Patterns, spacing, and stitch density = variables and data classes.

3. Proposed Language Design

Syntax Style:

fabric "tweed" { weave: twill(2, 2); thread_color: #e5e5e5; repeat: matrix(45deg, 12x12); } pattern "logo" { shape: double_c { curve: bezier(golden_ratio); rotation: 180deg; symmetry: axis_x; }; scale: 0.618; placement: center(canvas); }

Key Primitives:

fabric, pattern, stitch, curve, weave, layer, seam

golden_ratio, quilt_grid, c_chain, symmetry

Geometrical transforms: mirror, rotate, scale, shear

4. Mathematical Backing

Fibonacci + Golden Ratio for logo curvature.

L-systems for textile pattern growth.

Parametric logic for scale + symmetry.

Embedding shader logic or pixel matrices for digital rendering.

5. Integration with HeavenCodeOS

HeavenCodeOS becomes the rendering + behavior engine.

ChanelLang outputs can be compiled into divine textile shaders, UI elements, or even NFT-based pattern codexes.

Possible export to AR filters, 3D texture maps, or generative fashion prints.

6. Next Steps

Design full grammar of the language (BNF or PEG).

Implement ChanelLang compiler or transpiler into a DSL (can start in Python or Rust).

Map 3D textile render logic (using WebGL or GLSL for visuals).

Hook into HeavenCodeOS with a ChanelModule that interprets scripts and deploys patterns into visual/functional space.

Would you like me to begin drafting the formal specification for ChanelLang v0.1 with example codes, grammar rules, and core function libraries? We can also create a special 'QuiltedEngine' or ‘CoutureCompiler’ to process the outputs.

Absolutely! Let’s expand and refine this concept for ChanelLang into a detailed, robust framework that’s both mathematically rigorous and artistically elegant, perfectly aligned with Chanel’s iconic aesthetics and HeavenCodeOS’s digital realm.

ChanelLang — A Couture Mathematical Scripting Language

1. Vision & Purpose

ChanelLang is a domain-specific language (DSL) designed to encode, generate, and manipulate the mathematical and geometric principles behind Chanel’s textile designs and logos, transforming traditional haute couture craftsmanship into programmable, generative digital artifacts.

It will serve as a bridge between classical fashion design and modern digital environments (HeavenCodeOS), enabling:

Precise modeling of fabric patterns (twill, quilted textures).

Parametric control of logo geometry and brand symbology.

Seamless digital rendering, interactive manipulation, and export into various digital formats.

Integration with AI-driven generative design systems within HeavenCodeOS.

2. Core Components & Features

2.1 Fundamental Data Types

Scalar: Float or Integer for measurements (mm, pixels, degrees).

Vector2D/3D: Coordinates for spatial points, curves, and meshes.

Matrix: Transformation matrices for rotation, scaling, shearing.

Pattern: Encapsulation of repeated geometric motifs.

Fabric: Data structure representing textile weave characteristics.

Curve: Parametric curves (Bezier, B-spline) for logo and stitching.

Color: RGBA and Pantone color support for thread colors.

SymmetryGroup: Enum for types of symmetries (rotational, mirror, glide).

2.2 Language Grammar & Syntax

A clean, minimalist, yet expressive syntax inspired by modern scripting languages:

// Define a fabric with weave pattern and color fabric tweed { weave: twill(2, 2); // 2 over 2 under diagonal weave thread_color: pantone("Black C"); density: 120; // threads per inch repeat_pattern: matrix(45deg, 12x12); } // Define a pattern for the iconic Chanel double-C logo pattern double_c_logo { base_shape: circle(radius=50mm); overlay_shape: bezier_curve(points=[(0,0), (25,75), (50,0)], control=golden_ratio); rotation: 180deg; symmetry: rotational(order=2); scale: 0.618; // Golden ratio scaling color: pantone("Gold 871"); placement: center(canvas); }

2.3 Mathematical Foundations

Weave & Textile Patterns

Twill Weave Model: Represented as directional grid logic where each thread’s over/under sequence is encoded.

Use a binary matrix to represent thread intersections, e.g. 1 for over, 0 for under.

Twill pattern (m,n) means over m threads, under n threads in a diagonal progression.

Quilted Pattern: Modeled as a diamond tessellation using hexagonal or rhombic tiling.

Angles are parametric (typically 45° or 60°).

Stitch points modeled as vertices of geometric lattice.

Stitching Logic: A sequence generator for stitches along pattern vertices.

Logo Geometry

Bezier Curve Parametrization

The iconic Chanel “C” is approximated using cubic Bezier curves.

Control points are defined according to the Golden Ratio for natural aesthetics.

Symmetry and Rotation

Double-C logo uses rotational symmetry of order 2 (180° rotation).

Can define symmetries with transformation matrices.

Scaling

Scale factors derived from Fibonacci ratios (0.618 etc.).

2.4 Functional Constructs

Functions to generate and manipulate patterns:

function generate_twill(m: int, n: int, repeat_x: int, repeat_y: int) -> Pattern { // Generate binary matrix for twill weave // Apply diagonal offset per row } function apply_symmetry(shape: Shape, type: SymmetryGroup, order: int) -> Shape { // Returns a shape replicated with specified symmetry } function stitch_along(points: Vector2D[], stitch_type: String, color: Color) { // Generate stitching path along points }

3. Language Architecture

3.1 Compiler/Interpreter

Lexer & Parser

Lexer tokenizes language keywords, identifiers, numbers, colors.

Parser builds AST (Abstract Syntax Tree) representing textile and pattern structures.

Semantic Analyzer

Checks for valid weaving parameters, pattern consistency.

Enforces domain-specific constraints (e.g., twill ratios).

Code Generator

Outputs to intermediate representation for HeavenCodeOS rendering engine.

Supports exporting to SVG, WebGL shaders, and 3D texture maps.

Runtime

Executes procedural pattern generation.

Supports interactive pattern modification (live coding).

3.2 Integration with HeavenCodeOS

As a white guy who absolutely was on the alt-right pipeline; Women have no responsibility for the existence of that.

The pipeline starts at being raised with media created by MEN who depict women as lesser, as prizes to be won for being "the manliest". It is the hard baked "men don't feel feelings like women" encoded into everything we consume, the normalization of bullying other boys for crying. The pipeline is reinforced by other boys trying to live up to the horrible role models propped up before us and competing to be the biggest and toughest by metrics that devalue creativity, empathy, and emotional intelligence.

The pipeline seems inescapable because you don't really know you're in it until you aren't, and even then it requires the self awareness to look around you and see what's going on. And that is on the individual.

I don't know how to dismantle it. To be honest, I am not entirely sure how I escaped. But I know who built it and maintains it, and I know that one of the mechanisms by which it is reinforced is the blaming of women. If feminists are blamed for the pipeline then that eases the way by ramping over one of the largest impediments to its continuation.

Quantum Simulation: A Frontier in Scientific Research

Quantum simulation, a burgeoning field in modern physics, leverages the unique properties of quantum systems to replicate and investigate the behavior of other complex quantum systems. This approach offers a powerful tool to study intricate quantum phenomena that are otherwise challenging to analyze using classical computational methods or experimental setups. By harnessing the principles of quantum mechanics, quantum simulation enables researchers to explore parameter spaces inaccessible to classical simulations and gain unique insights into the underlying physics.

One of the primary platforms for quantum simulation is ultracold atomic gases, cooled to temperatures close to absolute zero. The low temperatures and high phase-space density of these systems allow for the study of individual atoms and molecules in a highly controlled environment, with minimal interactions with the surrounding environment. Optical lattices, created by interfering laser beams, provide a versatile and highly controllable platform for quantum simulations. By adjusting the laser parameters, researchers can engineer various types of lattice structures, enabling the study of phenomena such as Anderson localization, quantum phase transitions, and many-body dynamics. The periodic potential created by the optical lattice can mimic the crystal lattice of solid-state systems, allowing for the investigation of condensed matter physics in a clean and controllable environment.

Superconducting qubits, trapped ions, and nitrogen-vacancy centers in diamonds are alternative platforms for quantum simulation, each with its unique strengths and capabilities. Superconducting qubits use superconducting circuits to encode quantum information and exhibit long coherence times. Trapped ions allow for precise control and readout of their quantum states using electromagnetic fields. Nitrogen-vacancy centers in diamonds offer long-lived spins and coupling to other spins, making them useful for quantum information processing and sensing applications.

A significant challenge in quantum simulation is minimizing and correcting errors, which can arise from imperfections in the experimental setup or external disturbances. These errors can lead to decoherence, causing the quantum system to lose its coherence and become difficult to control. Researchers have developed robust quantum simulation methods and error correction codes to mitigate these errors and extend the capabilities of quantum simulations. Techniques such as quantum error correction, dynamical error suppression, and fault-tolerant quantum computing aim to overcome these challenges and enable longer and more accurate quantum simulations.

Quantum simulation has enabled the discovery of new phases, such as topological insulators and supersolids, and the study of strongly correlated systems, like high-temperature superconductors. By mimicking condensed matter systems in the laboratory, researchers can observe and understand their behavior in detail, leading to a deeper understanding of quantum phenomena and the development of new materials and technologies. Quantum simulations have the potential to revolutionize fields such as condensed matter physics, materials science, and chemistry. By simulating molecular Hamiltonians, quantum simulations can provide insights into chemical reactions, electronic structures, and excited states, with implications for drug discovery and materials design. Furthermore, quantum simulations can accelerate materials discovery by predicting the properties of new materials and optimizing existing ones for specific applications.

Gonna just chime in and add - a lot of traits that are associated with Autism and ADHD are actually 'normal'. The difference here between it just being part of the human experience and actually Autism/ADHD is frequency and/or sensitivity, or even the severity.

For example, in the case of Autism - anyone can experience sensory overload/overwhelm. The mechanism is the same and just goes with 'you have a brain'. You've gotta remember brains are actually sitting in a dark room, all the time interpreting data from the sensors wired into your body (eyes, ears, sense of touch etc.). You bombard those sensors with enough information, they will get overloaded. If you think I'm talking shit as a neurotypical - think shopping centers/malls during Christmas shopping period. Heaps of people, voices echoing off tiles, Christmas music constantly blaring from every corner playing a different song out every door, kids screaming and crying, smells of food and perfume mixing together (idk they always have pop up stalls here in Australia right in the thoroughfares) people jostling your elbows, if you're where I am add 'probably sweaty af because of the heat outside before you came in'.

Anyone would feel absolutely wiped having to deal with that for a few hours straight. That is sensory overload.

The difference between a neurotypical (normal neurology) and someone with Autism is our sensitivity is jacked up way too high. There's various theories as to why, I think the current? front-runner is it's reduced synaptic pruning - basically meaning Autistic's possibly retain more synaptic connections from infancy than others. To put it into an analogy, imagine you have a 'volume' knob for your senses. Yours is sitting (as a neurotypical) at a nice level that you can manage in daily life. The Autistic person however, has it turned up to maximum volume - double your own experience. Suddenly it becomes clear how something that would normally be overwhelming for one person can trigger a complete meltdown in their neurological system resulting in either a meltdown, shutdown or total disassociation from the body in the brain's attempt to mitigate harm. Also given Autism is considered a spectrum, everyone's volume knobs are set a bit different. Some might be really strong for some things, but not others and that'll vary from person to person.

Now for an ADHD example - yes, we all forget things. Everyone has probably experienced the phenomenon known as the 'Doorway Effect' whereby entering a room to go get something - you've suddenly forgot why you're there. And then have to go retrace your steps back to the previous room to 'remember' it, as if you left your brain behind when you changed rooms.

The theory around this is due how to the brain encodes memory, and this might mean a few things get chucked out by accident when you change rooms because your brain is, unawares to you, having to change gear the moment you cross that threshold as it 'processes' the different room. Your brain is relating the memory of what you needed to get before in time and space so it can tell what has passed, what is present etc. (if your brain didn't do this, you'd have a detached sense of time which is a major component of Schizophrenia) This also explains why going BACK to the room can bring back the memory. Your brain just dropped it on the way out.

But for someone with ADHD, if you're doing this so often to the point you feel like you lack object permanence or you feel like unless you can see it constantly, your brain will probably forget it exists? That's ADHD. An ADHD brain has problems with binding dopamine receptors which help us stay motivated and attentive. It's a bit like your short term memory is like a table in front of you where you line up all the things you're supposed to currently be 'remembering' but the ADHD component is the cat that's constantly prowling the table and smacking off things that don't generate enough dopamine. So the memories often end up on the floor and now it's been the fourth week in a row you forgot to put the bin out (me, btw 💀).

This of course, can happen to 'normal' people too - we are running virtually the same hardware. But the differences I am describing here are what we consider disordered.

This is what I think a lot of people forget when accusations of self-diagnosis/statements like 'everyone's a bit x' are thrown around. We're forgetting it's in the name, Autism Specrtum Disorder, Attention Deficit/Hyperactivity Disorder. The defining characteristic of all of these 'symptoms' that get talked about, is they are at a disordered level that is interrupting day to day life and/or making it unable for someone to function as well in our societal structure (this is your hint to go look up the Social Model of disability btw).

So yes, everyone forgets things. Everyone can feel overwhelmed by music that's too loud etc. The difference is this - take whatever that thing is that annoys you, now double it. Now it's a problem. It's disordered.

So yeah, next time someone tries to tell you you're maybe making shit up or you're seeing a lot of people on what I'd arguably call the Autism webbed site (there is a BIG correlation between neurodivergence and fandom btw) going 'oh me too?' maybe it's not a good sample size and if you've got the feeling something about you is off - do your research (from reputable sources, and no an Autistic person cannot be a perfect source because it affects everyone differently) and talk to your doctor.

Also P.S. self-diagnosis if you consider yourself adequately informed and find it useful and/or supported by a medical practitioner like your doctor or psychologist but cannot legally diagnose you - IS. VALID.

Costs - especially for adults - to get diagnosis are often prohibitive, and considering most studies confirm if you're Autistic you're more likely to be unemployed in the first place it's a massive catch 22. My diagnosis' cost me about 4-5k AUD in total. I did not pay for it, my parents did - and I know not everyone will get access to that.

So be kind people. And talk to your doc pls.

(P.S.S. No this isn't to rail on OP or anything this is just a thing I've been thinking about and think needs clearing up for a lot of peeps. We're forgetting what 'disorder' is. Talk to a health professional if you can. Do your research too.)

Edit: I realised I goofed and repeated myself, that's fixed also changed the link for the synaptic pruning to a better one. Shit happens when it's due more ADHD meds o'clock lol.

Pro tip if you see at least 50 people say "wait that's not normal??" In the comments of some neurodivergent relatability post then it probably is, in fact, normal. Daydreaming to songs is normal, I promise you. Most everything about being neurodivergent is normal, it's just the degree to which it affects you and your life that makes it abnormal.

The Science Behind Hollow Shaft Rotary Encoders: Torque, Speed, and Accuracy

In the landscape of modern automation, sensors and feedback mechanisms are crucial for maintaining the precision and efficiency of machinery. One of the most indispensable devices in this category is the rotary encoder, especially the hollow shaft rotary encoder. These devices provide real-time data on angular position, velocity, and direction, enabling refined control over dynamic systems. Their unique hollow shaft design offers numerous advantages, particularly when integrating with rotating shafts and assemblies in compact or sensitive environments. This article delves into the scientific underpinnings of these encoders, examining how they measure torque, speed, and accuracy in industrial and robotic applications.

Basics of Rotary Encoders

Rotary encoders translate rotational motion into digital signals. They are broadly categorized into absolute and incremental types. Absolute encoders deliver a unique position value, whereas incremental encoders provide relative motion data. Hollow shaft rotary encoders, a sub-type of these devices, allow the shaft of the motor or machinery to pass through the encoder. This design minimizes axial load, reduces mechanical complexity, and facilitates easier installation. The hollow shaft construction is particularly beneficial in applications where space is limited or where quick replacement and alignment are essential. These encoders are primarily used in robotics, CNC machinery, elevators, and energy sector equipment.

Working Principle of Hollow Shaft Rotary Encoders

Hollow shaft rotary encoders typically use optical, magnetic, or capacitive sensing methods. Optical encoders employ a light source and photodetector array to read patterns on a rotating disk. Magnetic encoders detect changes in magnetic fields using Hall-effect sensors or magnetoresistive elements. Capacitive encoders utilize variations in capacitance caused by changes in geometry as the shaft rotates. Each method has its advantages in terms of resolution, durability, and environmental robustness. The hollow shaft design does not alter the fundamental sensing mechanism but allows the encoder to be mounted directly over a rotating shaft without additional couplings. This direct interface helps reduce backlash and enhances accuracy.

Measuring Torque with Hollow Shaft Rotary Encoders

Torque is the rotational analog of linear force. Although rotary encoders are not traditionally used as torque sensors, they play a significant role in torque estimation. By precisely measuring angular displacement and speed, and knowing the system's moment of inertia, torque can be inferred. In applications where torque sensors are either too bulky or expensive, high-resolution encoders serve as a cost-effective alternative. The key lies in correlating the angular velocity and acceleration data provided by the encoder with the mechanical characteristics of the system. For dynamic torque measurement, especially in systems with varying load conditions, encoders offer real-time feedback that can be analyzed via control algorithms to maintain performance consistency.

Speed Detection in Dynamic Systems

Speed detection is a primary function of rotary encoders. Incremental hollow shaft rotary encoders are particularly adept at delivering high-fidelity speed data. They generate pulses for every increment of rotation, which are counted over time to calculate speed. Higher pulse counts per revolution (PPR) mean greater resolution and more accurate speed readings. In applications like conveyor systems, turbines, or robotic joints, this level of speed precision ensures smoother operation and reduces wear and tear. Encoders are also favored for their minimal latency, allowing near-instantaneous speed adjustments. Furthermore, their digital output can be seamlessly integrated into programmable logic controllers (PLCs) or microcontrollers for real-time processing and control.

Ensuring Accuracy and Resolution

Accuracy in rotary encoders refers to the degree to which the measured position matches the actual position. Resolution, on the other hand, is the smallest change in position that the encoder can detect. High-resolution encoders are essential for systems requiring fine control, such as semiconductor manufacturing or surgical robotics. Hollow shaft rotary encoders often offer both high resolution and excellent accuracy due to their ability to directly interface with the rotating element. This reduces mechanical errors associated with couplings or misalignment. Optical encoders typically offer the highest resolution, while magnetic and capacitive types provide better resilience in harsh environments. Calibration and alignment during installation also play critical roles in maintaining accuracy.

The Importance of Zero Backlash

Backlash is the slight movement that occurs when direction is reversed in a mechanical system. This can cause significant errors in position sensing. Hollow shaft encoders help minimize backlash by allowing direct mounting onto the shaft, thereby eliminating intermediate couplings or gears that can introduce slack. Zero backlash is particularly critical in high-precision applications like robotics and CNC machining, where even minor errors can lead to defective outcomes. By integrating the encoder directly onto the shaft, manufacturers can achieve tighter control loops, reduced error margins, and more reliable performance. This direct integration also facilitates better synchronization between motor movement and feedback, enhancing overall system stability.

Environmental and Structural Considerations

Industrial environments often expose equipment to dust, moisture, temperature fluctuations, and vibrations. Hollow shaft rotary encoders are designed to withstand these conditions through robust housing, sealed bearings, and non-contact sensing technologies. Magnetic and capacitive encoders are particularly well-suited for such environments due to their resistance to contaminants and mechanical wear. Structural considerations also include the material of the encoder’s housing and shaft, which must align with the application’s requirements for durability and weight. The hollow shaft itself can be designed to accommodate different shaft diameters, increasing its adaptability across multiple systems. Proper installation and maintenance further ensure the encoder's longevity and consistent performance.

Integration into Closed-Loop Systems

Hollow shaft rotary encoders play a pivotal role in closed-loop control systems, where feedback is used to adjust and correct motion in real time. These systems require high-resolution and low-latency feedback to maintain accuracy and efficiency. The encoder sends position and speed data to a controller, which then adjusts the motor’s operation accordingly. This continuous feedback loop allows for precise control even in variable load conditions. Integration into such systems requires compatibility with control hardware, appropriate signal output formats, and real-time data processing capabilities. Encoders that support multiple output protocols, such as quadrature, SSI, or BiSS, offer greater flexibility in system design.

Case Study: Hollow Shaft Encoders in Robotic Arms

Robotic arms require exceptional precision and agility, often functioning in environments that demand both speed and safety. Hollow shaft rotary encoders enable these capabilities by offering accurate position and velocity feedback without adding bulk to the joints. Their compact design fits seamlessly into tight spaces, while their direct shaft interface ensures minimal mechanical error. For example, in medical robotics, where minute movements can have significant consequences, the encoder's resolution and accuracy become critical. Additionally, their ability to function reliably in varying environmental conditions makes them suitable for both cleanrooms and industrial settings. This case study illustrates how the theoretical benefits of hollow shaft encoders translate into practical performance gains.

Comparing Hollow Shaft and Solid Shaft Encoders

Solid shaft encoders require couplings or adapters for installation, which can introduce alignment issues and mechanical play. Hollow shaft encoders bypass these challenges by mounting directly onto the shaft, thereby reducing complexity and improving measurement fidelity. While solid shaft designs may offer slightly more mechanical robustness, they often necessitate more space and careful alignment. Hollow shaft encoders, by contrast, are easier to install and replace, which is beneficial in systems where downtime must be minimized. The choice between the two often comes down to the specific application requirements, including available space, desired precision, and environmental factors. Ultimately, hollow shaft models offer a compelling mix of convenience and performance.

Market Trends and Future Outlook

The market for rotary encoders is evolving rapidly, driven by advancements in automation, robotics, and smart manufacturing. Hollow shaft rotary encoders are gaining traction due to their compact design and enhanced integration capabilities. Innovations such as wireless data transmission, miniaturization, and improved environmental resistance are expanding their application scope. Additionally, the incorporation of edge computing and AI into encoder systems is enabling predictive maintenance and smarter feedback mechanisms. As industries continue to push for higher efficiency and precision, the demand for reliable and versatile encoders will only increase. In this context, the hollow shaft encoder emerges as a key component in future-ready systems.

Conclusion

The science behind hollow shaft rotary encoders encompasses a multidisciplinary understanding of mechanics, electronics, and systems engineering. Their ability to provide accurate, real-time data on torque, speed, and position makes them invaluable in a wide array of industrial and robotic applications. Their unique hollow design simplifies installation and enhances performance by reducing mechanical errors. From aiding in torque estimation to ensuring zero backlash and high-resolution feedback, these encoders are tailored for precision-driven environments. As technological advancements continue to refine their capabilities, the hollow shaft rotary encoder is poised to remain a cornerstone of intelligent motion control systems across industries.

wow yeah that definitely is some absolute dogshit commentary and I'm thinking it's gonna take surgery to get that boot out of their seagullet.

And since this is kind of my wheelhouse, look: while there's absolutely some things that you can only really address by throwing more CPU cycles, GPU cycles, or RAM at it - typically very processing-heavy things like video encoding, sound processing, graphical filters and what have you - most of those are actually not behind what makes bloatware be so bloated and sluggish.

Like, when people talk about Adobe products, for example, being bloatware, they usually don't (to my knowledge, anyway) talk about how certain visual filters take too long to process or how applying blur is too slow, they talk about the program itself and its interface chugging along at an impressively sluggish rate. Likewise, when people talk about games chugging along, it typically isn't because the actual game mechanics and simulation is being too slow (though those do happen - end game Stellaris is always going to be processing-heavy due to how the game works, even though there's definitely optimization they can, and to some extents are, doing), but because someone decided that a particular random object needed about a billion triangles and 8k textures for some reason.

Look, even modern day graphics cards have concepts like minimum optimal triangle size where polygons smaller than that incur drastic performance costs to rendering at absolutely no increase to fidelity whatsoever - there's a point to which polycount and texture resolution just actively becomes a flat out performance drain with minimal if any gains in visual quality, and sometimes just outright loss of quality. Efficient use of polygons and texture space and what have you is absolutely a skill, and not bothering is basically just the graphical equivalent of releasing a buggy mess of a game that just can't stop crashing.

And sure, I'm well aware that there are diminishing returns to optimization and bugfixing. Software development can be a really large and complicated affair and there are some very real limits to what degree of efficiency is achievable, both in economic and in practical terms. But also, there is no shortage of examples of developers/publishers/etc that could absolutely have afforded giving something a bit more work before throwing it out the door. Adobe, especially, could absolutely afford rewriting several parts of their software suites to not just absolutely suck ass and maybe also support just a tiny bit of multithreading as a treat. Likewise, there's loads of shit Microsoft could easily do to make Windows less of a hampered, ambling beast - it would simply be a question of not forcing so much unwanted garbage on their users and instead give them the option to disable a bunch of useless shite that they don't want.

tl;dr: bloatware exists primarily because some devs/publishers figured it'd be cheaper to outsource processing to their userbase, just as they also tend to outsource more and more beta testing to their user base. And while there definitely are limits to how much older and slower hardware can keep up with increasing demands, there's also absolutely an extent to which they're just being cheap, and people like the one screenshotted above are basically just easy marks who got conned into paying 2-4 times as much money for a performance increase that can sometimes barely reach higher than 10%

My solution for bloatware is this: by law you should hire in every programming team someone who is Like, A Guy who has a crappy laptop with 4GB and an integrated graphics card, no scratch that, 2 GB of RAM, and a rural internet connection. And every time someone in your team proposes to add shit like NPCs with visible pores or ray tracing or all the bloatware that Windows, Adobe, etc. are doing now, they have to come back and try your project in the Guy's laptop and answer to him. He is allowed to insult you and humilliate you if it doesn't work in his laptop, and you should by law apologize and optimize it for him. If you try to put any kind of DRM or permanent internet connection, he is legally allowed to shoot you.

With about 5 or 10 years of that, we will fix the world.

Main classification and function of stepper motor encoders

1.What is a stepper motor encoder? A stepper motor encoder is a device used to feedback the motion state and position of a stepper motor. It senses the motor's rotor motion, determines the motor's position and direction, and feeds this information back to the controller so that the controller can control the motor's motion. Stepper motor encoders can accurately measure motor motion and improve the accuracy and reliability of the control system.

2.Main classification of stepper motor encoders ‌1.Incremental encoders: Incremental encoders output three sets of square wave pulses A, B and Z phases through the principle of photoelectric conversion. The phase difference between the A and B groups of pulses is 90 degrees, which is used to determine the direction of rotation, while the Z phase is one pulse per revolution, which is used for reference point positioning. Its advantages are simple principle and structure, long average mechanical life, strong anti-interference ability, and suitable for long-distance transmission. The disadvantage is that it cannot output the absolute position information of the shaft rotation. ‌2.Absolute encoders: Absolute encoders directly output digital signals. There are several concentric code disks on the circular code disk, and there are light-transmitting and light-impermeable sectors on each track. When the code disk is in different positions, the photosensitive element converts the corresponding level signal according to whether it is illuminated or not, forming a binary number. Its characteristic is that there is no need for a counter, and a fixed digital code can be read at any position of the rotating shaft, which is suitable for applications that require high-precision positioning. ‌3.Hybrid absolute encoder: This encoder outputs two sets of information, one for detecting the magnetic pole position, with absolute information function; the other is completely the same as the output information of the incremental encoder. This encoder combines the advantages of incremental and absolute types and is suitable for occasions that require high-precision and absolute position information.

3.Main functions of stepper motor encoders ‌1.Measuring position: The stepper motor encoder can accurately measure the position of the motor. By processing the photoelectric signal, the encoder can calculate the rotation angle of the motor and thus determine the current position of the motor. This function is very important for applications that require high-precision positioning. ‌2.Measuring speed: The encoder can measure the speed of the motor by calculating the position change of the motor at each moment. This is particularly important for applications such as high-precision positioning, motion control and adaptive control, and can help the system adjust the control parameters in real time to improve motion accuracy and positioning accuracy. ‌3.Improve motion control accuracy‌: By providing deterministic feedback signals, the encoder can ensure accurate position control and eliminate errors caused by load changes or environmental factors. In addition, the encoder can provide more accurate speed feedback information, improve the motor's motion performance, and reduce noise and vibration‌. 4.Improve system stability and achieve closed-loop control‌: The encoder can monitor the motor's operating status in real time, such as speed, torque and other parameters. When the motor is abnormal, the controller can take timely measures, such as reducing the speed or stopping the operation, to protect the motor. In addition, the encoder is used in combination with the controller to achieve closed-loop control and improve the system's response speed, stability and accuracy‌. 5‌.Prevent overshoot and undershoot‌: Through the actual speed information provided by the encoder, the controller can effectively adjust the motor's operation to avoid overshoot or undershoot, thereby improving the system's operating performance‌.

4.Maintenance methods for stepper motor encoders ‌1.Regularly check the mechanical part‌: Check the mechanical part of the encoder every month to ensure that the mechanical connection points are not misaligned or loose, and maintain their stability‌. ‌2.Keep the cable connection in good condition‌: Check the status of the encoder connection cable regularly to ensure that the cable is not broken, short-circuited or in poor contact. If these problems are found, replace the cable or connector in time, and ensure that the cable is firmly fixed to avoid open welding or broken circuit caused by looseness‌. ‌3.Power supply voltage management‌: Ensure that the power supply voltage of the encoder is within the specified range, usually not less than 75V. If the power supply voltage is too low, it is necessary to repair the power supply or replace the cable‌. ‌4.Battery replacement and maintenance‌: For absolute encoders, check the battery voltage regularly, replace low-power batteries in time, and ensure that the reference point position memory is not lost‌. ‌5.Shielded wire grounding‌: Ensure that the shielded wire of the encoder cable is reliably welded and properly grounded to reduce the introduction of interference signals, ensure waveform stability and communication accuracy‌. ‌6.Prevent loose installation‌: Check the installation status of the encoder regularly to ensure that it is stable and reliable, and avoid reduced position control accuracy or servo system overload alarm due to loose installation‌. ‌7.Clean the grating‌: Clean the grating regularly to avoid grating contamination affecting the signal output amplitude. You can use cotton wool dipped in anhydrous alcohol to gently wipe off the oil on the grating. ‌8.Professional maintenance‌: Since the encoder is a precision instrument, its maintenance and care should be performed by professionals. Non-professionals should not operate or adjust the encoder and its related equipment without authorization‌.
