# Luke Smith
|
||||
|
||||
Luke Smith is an Internet tech mini-celebrity known for making videos about [suckless](suckless.org) software, independent living in the woods and here and there about historical, political, linguist and religious topics. His look has been described as the *default Runescape character*: he is bald, over 30 years old and lives in a rural location in Florida (exact coordinates have been doxxed but legally can't be shared here, but let's just say the road around his house bears his name). He has a podcast called *Not Related!* in which he discusses things such as alternative historical theories -- actually a great podcast. He has a minimalist 90s style website https://lukesmith.xyz/ and his own [peertube](peertube.md) instace where his videos can be watched if one doesn't want to watch them on [YouTube](youtube.md). He is the author of [LARBS](larbs.md) and minimalist recipe site https://based.cooking/. Unfortunately he's a [crypto](cryptocurrency.md) and [brave](brave.md) browser shill.

He's kind of based when it comes to many things but also retarded to a great degree other times, for example he used to shill the [Brave](brave.md) browser pretty hard before he realized it was actually a huge scam all along xD He's a crypto fascist, also probably a Nazi. In July 2022 he started promoting some shitty [bloated](bloat.md) [modern](modern.md) tranny website generator that literally uses [JavaScript](js.md)? WHAT THE FUCK. 100% he's getting paid for that promotion. He seems to be going to huge shit. It sadly seems like he's just another [capitalist](capitalism.md), so we recommend slowly unsubscribing from this guy's feed.

Also he's shilling [crypto](crypto.md), he's anti-[porn](porn.md), anti-[games](game.md) and leans towards medieval ideas such as imagination and boredom being [harmful](harmful.md) because it makes you search for porn etc. He seems to be going to huge [shit](shit.md). Though he makes [suckless](suckless.md) more popular, he isn't a programmer (shell scripting isn't programming) and sometimes doesn't seem to understand the ideas in depth, he's more of a typical [productivity](productivity_cult.md) retard. It sadly seems like he's just another [capitalist](capitalism.md), so we recommend slowly unsubscribing from this guy's feed.

Luke is a [type B fail](fail_ab.md).
|
||||
|
||||
His videos consist of normie-friendly tutorials on suckless software, rants, independent living, live-streams and podcasts. The typical Luke Smith video is him walking somewhere in the middle of a jungle talking about how retarded modern technology is and how everyone should move to the woods.
|
||||
|
||||
Luke studies PhD in linguistics but is very critical of academia -- he "speaks" several languages (including [Latin](latin.md)), though many of them to a low level with bad American accent and he can't sometimes even speak English correctly (using phrases such as "the reason is because", "less people" etc.). He is a self described [right-winder](left_right.md) and talks in meme phrases which makes his "content" kind of enjoyable. He despises such things as [soydevry](soydev.md), [bloat](bloat.md), "consoomerism" and [soyence](soyence.md).

# Newspeak
|
||||
|
||||
Newspeak is a modified form of natural language (e.g. [English](english.md)) twisted for the purpose of thought control of mass population, with [propaganda](propaganda.md) and ideology built in so as to affect thinking of people in a way desired by the rulers of society. It first appeared in George Orwell's 1949 book called [Nineteen Eighty Four](1984.md) and started to become significantly implemented in [real world](irl.md) since about the end of 20th century by the [pseudoleft](pseudoleft.md) and capitalists (i.e. [liberals](liberal.md)). Refusing to use newspeak is labeled [thought crime](thought_crime.md), [hate speech](hate_speech.md) or psychological disorder and punished either officially by government or unofficially by society-approved and state-tolerated lynching (so called [cancelling](cancel_culture.md)).

Real world newspeak is characterized by banning certain keywords, for example so called [slurs](slur.md) such as [nigger](nigger.md), [faggot](faggot.md) or [retard](retard.md), as well as inventing [euphemisms](euphemism.md) for [harmful](harmful.md) and oppressive concepts ([copyright](copyright.md) instead of copyrestriction, [moderation](moderation.md) instead of [censorship](censorship.md) etc.), redefining the meanings of existing terms such as [racism](racism.md) (originally hating people of certain race, now anyone who disagrees with mainstream pseudoleft ideology), [homophobia](homophobia.md) (originally hating gay people, now anyone who disagrees with pseudoleft ideology regarding [LGBT](lgbt.md)), [rape](rape.md) (originally sexual violence, now any action taken by man towards a woman) and inventing completely new terms such as [hate speech](hate_speech.md) and [sanism](sanism.md) serving for eliminating ideological opposition and suppression of [free speech](free_speech.md).

# Noise
|
||||
|
||||
Noise in general is an undesirable [signal](signal.md) that's mixed in with useful signal and which we usually try to filter out, even though it can also be useful, especially e.g. in [procedural generation](procgen.md). Typical example of noise is flickering or static in video and audio signals, but it can also take a form of e.g. random errors in transferred texts, irrelevant links in web search results or imperfections in measuring of economic data. In measurements we often talk about [signal to noise ratio](snr.md) (SNR) -- the ratio that tells us how much noise there is in our data. While in engineering and scientific measurements noise is almost always something that's burdening us (e.g. [cosmic microwave background](cmb.md), the noise left over from the [Big Bang](big_bang.md), may interfere with our radio communication), in some fields such as [computer graphics](graphics.md) (and other computer [art](art.md)) or [cryptography](cryptography.md) we sometimes try to purposefully generate artificial noise -- e.g. in [procedural generation](procgen.md) noise is used to generate naturally looking terrain, clouds, textures etc.

## Artificial Noise
|
||||
|
||||
In [computer science](compsci.md), especially e.g. in [computer graphics](graphics.md) or audio generation, we often want to generate artificial noise that looks like real noise, in order to be able to generate data that look like real world data. Noise may serve as a basis (first step, random initial state) for generating something or it may be used to distort or modulate other data, for example when drawing geometrical shapes we may want them to look as if written by hand in which case we want to make them imperfect, add a bit of noise to an otherwise perfect shape a computer would create. Adding noise can help make rendered pictures look more natural, it can help us model human speech that arises from noise created by our vocal cords, it can help AI train itself to filter out real life noise etc.
|
||||
|
||||
Normally we don't want our noise to be completely [random](randomness.md) but rather **[pseudorandom](pseudorandomness.md)** so that our programs stay [deterministic](determinism.md). Imagine for example we are generating terrain [heightmap](heightmap.md) based on a 2D noise -- if such function was truly random, the terrain in a certain place would be different every time we returned to that place again, but if the noise is pseudorandom ([seeded](seed.md) by the position coordinates), the terrain generated at any given coordinate will be always the same.
|
||||
|
||||
There are different types of noise characterized by their properties such as number of dimensions, [frequencies](frequency.md) they contain, [probability distribution](probability.md) of the values they contain etc. Basic division of noises may be this:
|
||||
|
||||
- by type/[algorithm](algorithm.md):
|
||||
- **value noises**: The simplest type of noise, it arises by generating a (pseudo)random value at each node of the spatial grid. Values in between grid nodes are obtained by [interpolation](interpolation.md).
|
||||
- **gradient noises**: More sophisticated than value noise, rather than a simple value it generates a [gradient](gradient.md) at each grid point. Specific algorithms/types of gradient noise are:
|
||||
- **[Perlin noise](perlin_noise.md)**: One of the most common and basic gradient noises, which however suffers from some [artifacts](artifact.md).
|
||||
- **[simplex noise](simplex_noise.md)**: A more sophisticated noise than Perlin noise, improves some of its properties, works with a [simplex](simplex.md) lattice of points rather than orthogonal grid.
|
||||
- ...
|
||||
- **spectral noises**: Noises that are generated in the [spectral domain](spectrum.md) (see [Fourier transform](fourier_transform.md)):
|
||||
- **[anisotropic noise](anisotropic_noise.md)**: Noise that has a specific orientation, can be used e.g. for water waves that go in one direction.
|
||||
- ...
|
||||
- **[convolution](convolution.md) noises**: Noises that use [convolution](convolution.md) of given kernel with some simpler noise to create a larger texture.
|
||||
- **[Gabor noise](gabor_noise.md)**
|
||||
- ...
|
||||
- other:
|
||||
- **[Voronoi](voronoi.md) noise**: Noise that looks like a "honeycomb" or structures created by living cells, it is created by generating random point coordinates and then assigning each space point (e.g. each pixel) a [distance](distance.md) to its closest point. Different random [point sampling](point_sampling.md) methods or distance functions can help change the look of the noise. Worley Noise is one type of Voronoi noise.
|
||||
- Combinations and modifications of standard noises: we may e.g. blend or [modulate](modulation.md) two noise functions to create a new complex type of noise.
|
||||
- **[midpoint displacement](midpoint_displacement.md)/[diamond square](diamond_square.md)**: Relatively simple [algorithms](algorithm.md) for generating [fractal](fractal.md) heightmaps, working on the principle of repeatedly subdividing a line (or in higher dimensions a square, cube etc.) and (pseudo)randomly displacing the generated point.
|
||||
- **[wavelet noise](wavelet_noise.md)**: Noise further improving some characteristics of Perlin noise.
|
||||
- unorthodox noises created e.g. by [cellular automata](cellular_automaton.md), AI etc.
|
||||
- ...
|
||||
- by frequencies:
|
||||
- **[fractal noise](fractal_noise.md)**: Very important type of noise that similarly to [fractals](fractal.md) is composed of differently scaled versions of itself -- this noise looks like (and can be used to simulate) clouds, mountains and other structures found in nature. It is created by taking some basic noise function (e.g. Perlin noise or simplex noise) and overlaying (adding) multiple versions of it that differ by frequency and amplitude (just as e.g. mountains are composed of big and tall hills that have on them progressively smaller and less tall hills up to the microscopic level). These different individual layers are called octaves: *i*th octave has the amplitude *p^i* (where *p* is a constant from 0 to 1 called a persistence) and frequency of *2^i*.
|
||||
- **[white noise](white_noise)**: Noise containing "same amount of all frequencies" -- this is basically the simplest kind of noise we get when we generate a sequence of independent ([uncorrelated](correlation.md)) (pseudo)random numbers with uniform probability distribution.
|
||||
- **[pink noise](pink_noise.md)**: Energy density of frequencies decreases proportionally with 1/frequency, i.e. it basically has strong high frequencies and weak low frequencies.
|
||||
- **[blue noise](blue_noise.md)**
|
||||
- ...
|
||||
- by other properties:
|
||||
- **symmetry/invariance** and other function properties: A noise may or may not be invariant against various operations such as shifting, rotation or scaling, i.e. when we apply this operation it will look basically the same. For example Perlin noise outputs value 0 at each grid point and is non-zero only between the grid point, so it is NOT invariant towards shifting. Noise functions are just mathematical [functions](function.md), so we may examine noises just as we examine functions (they may be continuous, bounded etc.).
|
||||
- **explicit vs implicit**: Values of an implicit noise can relatively simply and quickly be computed at any given point in space whereas explicit noises require processing as a whole and therefore storage of the whole generated noise in memory.
|
||||
- **tiling**: Similarly to [procedural](procgen.md) [textures](texture.md), a noise generated by an algorithm may be tiling, i.e. not having visible seams when repeated in certain dimensions.
