# Assembly # Assembly
Assembly (also ASM) is, for any given hardware computing platform ([ISA](isa.md), basically a [CPU](cpu.md) architecture), the lowest level [programming language](programming_language.md) that expresses typically a linear, unstructured sequence of CPU instructions -- it maps (mostly) 1:1 to [machine code](machine_code.md) (the actual [binary](binary.md) CPU instructions) and basically only differs from the actual machine code by utilizing a more human readable form (it gives human friendly nicknames, or mnemonics, to different combinations of 1s and 0s). Assembly is converted by [assembler](assembler.md) into the the machine code, something akin a computer equivalent of the "[DNA](dna.md)", the lowest level instructions for the computer. Assembly is similar to [bytecode](bytecode.md), but bytecode is meant to be [interpreted](interpreter.md) or used as an intermediate representation in [compilers](compiler.md) while assembly represents actual native code run by hardware. In ancient times when there were no higher level languages (like [C](c.md) or [Fortran](fortran.md)) assembly was used to write computer programs -- nowadays most programmers no longer write in assembly (majority of zoomer "[coders](coding.md)" probably never even touch anything close to it) because it's hard (takes a long time) and not [portable](portability.md), however programs written in assembly are known to be extremely fast as the programmer has absolute control over every single instruction (of course that is not to say you can't fuck up and write a slow program in assembly). Assembly (also ASM) is, for any given hardware computing platform ([ISA](isa.md), basically a [CPU](cpu.md) architecture), the lowest level [programming language](programming_language.md) that expresses typically a linear, unstructured (i.e. without nesting blocks of code) sequence of CPU instructions -- it maps (mostly) 1:1 to [machine code](machine_code.md) (the actual [binary](binary.md) CPU instructions) and basically only differs from the actual machine code by utilizing a more human readable form (it gives human friendly nicknames, or mnemonics, to different combinations of 1s and 0s).

**Assembly is NOT a single language**, it differs for every architecture, i.e. every model of CPU has potentially different architecture, understands a different machine code and hence has a different assembly (though there are some standardized families of assembly like x86 that work on wide range of CPUs); therefore **assembly is not [portable](portability.md)** (i.e. the program won't generally work on a different type of CPU or under a different [OS](os.md))! And even the same kind of assembly language may have several different [syntax](syntax.md) formats which may differ in comment style, order of writing arguments and even instruction abbreviations (e.g. x86 can be written in [Intel](intel.md) and [AT&T](at_and_t.md) syntax). For the reason of non-portability (and also for the fact that "assembly is hard") you shouldn't write your programs directly in assembly but rather in a bit higher level language such as [C](c.md) (which can be compiled to any CPU's assembly). However you should know at least the very basics of programming in assembly as a good programmer will come in contact with it sometimes, for example during hardcore [optimization](optimization.md) (many languages offer an option to embed inline assembly in specific places), debugging, reverse engineering, when writing a C compiler for a completely new platform or even when designing one's own new platform. **You should write at least one program in assembly** -- it gives you a great insight into how a computer actually works and you'll get a better idea of how your high level programs translate to machine code (which may help you write better [optimized](optimization.md) code) and WHY your high level language looks the way it does. **Assembly is NOT a single language**, it differs for every architecture, i.e. every model of CPU has potentially different architecture, understands a different machine code and hence has a different assembly (though there are some standardized families of assembly like x86 that work on wide range of CPUs); therefore **assembly is not [portable](portability.md)** (i.e. the program won't generally work on a different type of CPU or under a different [OS](os.md))!

**OK, but why doesn't anyone make a portable assembly?** Well, people do, they just usually call it a [bytecode](bytecode.md) -- take a look at that. [C](c.md) is portable and low level, so it is often called a "portable assembly", though it still IS significantly higher in abstraction and won't usually give you the real assembly vibes. [Forth](forth.md) may also be seen as close to such concept. ACTUALLY [Dusk OS](duskos.md) has something yet closer, called [Harmonized Assembly Layer](hal.md) (see https://git.sr.ht/~vdupras/duskos/tree/master/fs/doc/hal.txt). [Web assembly](web_assembly.md) would also probably fit the definition. **OK, but why doesn't anyone make a portable assembly?** Well, people do, they just usually call it a [bytecode](bytecode.md) -- take a look at that.

The most common assembly languages you'll encounter nowadays are **[x86](x86.md)** (used by most desktop [CPUs](cpu.md)) and **[ARM](arm.md)** (used by most mobile CPUs) -- both are used by [proprietary](proprietary.md) hardware and though an assembly language itself cannot (as of yet) be [copyrighted](copyright.md), the associated architectures may be "protected" (restricted) e.g. by [patents](patent.md) (see also [IP cores](ip_core.md)). **[RISC-V](risc_v.md)** on the other hand is an "[open](open.md)" alternative, though not yet so wide spread. Other assembly languages include e.g. [AVR](avr.md) (8bit CPUs used e.g. by some [Arduinos](arduino.md)) and [PowerPC](ppc.md).

To be precise, a typical assembly language is actually more than a set of nicknames for machine code instructions, it may offer helpers such as [macros](macro.md) (something akin the C preprocessor), pseudoinstructions (commands that look like instructions but actually translate to e.g. multiple instructions), [comments](comment.md), directives, named labels for jumps (as writing literal jump addresses would be extremely tedious) etc. To be precise, a typical assembly language is actually more than a set of nicknames for machine code instructions, it may offer helpers such as [macros](macro.md) (something akin the C preprocessor), pseudoinstructions (commands that look like instructions but actually translate to e.g. multiple instructions), [comments](comment.md), directives, automatic inference of opcode from operands, named labels for jumps (as writing literal jump addresses would be extremely tedious) etc. I.e. it is still much easier to write in assembly than to write pure machine code even if you knew all opcodes from memory. For the same reason remember that just replacing assembly mnemonics with binary machine code instructions is not yet enough to make an executable program! More things have to be done such as [linking](linking.md) [libraries](library.md) and converting the result to some [executable format](executable_format.md) such as [elf](elf.md) which contains things like header with metainformation about the program etc.
Assembly is extremely low level, so you get no handholding or much programming "safety" (apart from e.g. CPU operation modes), you have to do everything yourself -- you'll be dealing with things such as function [call conventions](call_convention.md), [interrupts](interrupt.md), [syscalls](syscall.md) and their conventions, counting CPU cycles of individual instructions, looking up exact hexadecimal memory addresses, defining memory segments, dealing with [endianness](endianness.md), raw [goto](goto.md) jumps, [call frames](call_frame.md) etc. **How will programming in assembly differ from your mainstream high-level programming?** Quite a lot, assembly is extremely low level, so you get no handholding or much programming "safety" (apart from e.g. CPU operation modes), you have to do everything yourself -- you'll be dealing with things such as function [call conventions](call_convention.md), [interrupts](interrupt.md), [syscalls](syscall.md) and their conventions, counting CPU cycles of individual instructions, looking up exact hexadecimal memory addresses, opcodes, defining memory segments, dealing with [endianness](endianness.md), raw [goto](goto.md) jumps, [call frames](call_frame.md) etc. You have no branching (if-then-else), loops or functions, you make these yourself with gotos. You can't write expressions like `(a + 3 * b) / 10`, no, you have to write every step of how to evaluate this expression using registers, i.e. something like: load *a* to register *A*, load *b* to register *B*, multiply *B* by 3, add register *B* to *A*, divide *A* by 10. You don't have any [data types](data_type.md), you have to know yourself that your variables really represent signed values so when you're dividing, you have to use signed divide instruction instead of unsigned divide -- if you mess this up, no one will tell you, your program simply won't work. And so on.

This is the normal, to normalize it we'll first compute its length, i.e. *|n| = sqrt(3^2 + 4^2 + 12^2) = 13* and then divide each component of *n* by this length, i.e. we finally get *n0 = {3/13,4/13,12/13}*. As a check we can compute [dot product](dot_product.md) of this normal with both *U* and *V* and we should get 0 in both cases (meaning the vectors are perpendicular). 19. no

Infinite loop just performs jumps back to some previous program instruction which can be repeated indefinitely, so unless there is something inside the loop that will lead to a crash after many repetitions, an infinite loop will just make the program run forever.

25. Shading is the process of computing surface color of 3D objects, typically depending on the object's material and done by GPU programs called [shaders](shader.md); shading involves for example applying textures, normal mapping and mainly lighting -- though it can make pixels lighter and darker, e.g. depending on surface normal, it only applies local models of light, i.e. doesn't compute true shadows cast by other objects.

26. We can't really talk about Turing completeness of plain neural networks, they cannot be Turing complete because they just transform fixed length input into fixed length output -- a Turing complete model of computation must be able to operate with arbitrarily large input and output. In theory we can replace any neural network with logic circuit or even just plain lookup table. Significance of neural networks doesn't lie in their computational power but rather in their efficiency, i.e. a relatively small and simple neural network may replace what would otherwise be an enormously large and complicated circuit. 26.

30. The main difference against symmetric cryptography is we have two keys instead of one, one (private) for encrypting and one (public) for decrypting -- neither key can be used for the other task. Therefore encryption and decryption processes differ greatly (while in symmetric cryptography it's essentially the same, using the same key, just in reversed way), the problem looks different in one direction that the other, hence it is called *asymmetric*. 30. Yes, a false statement implies anything.
31. It's not the distance from the Sun (the distance doesn't change that much and it also wouldn't explain why opposite hemispheres have opposite seasons) but the tilted Earth axis -- the tilt changes the maximum height to which the Sun rises above any specific spot and so the angle under which it shines on the that spot; the [cosine](cos.md) of this angle says how much energy the place gets from the Sun (similarly to how we use cosine to determine how much light is reflected off of a surface in [shaders](shader.md)). 31.

32. 4 and 13, solution: make a table, columns are first integer, rows are second (remember, both *P* and *S* can be making their own table like this too). Cross out whole bottom triangle (symmetric values). *P* doesn't know the numbers, so cross out all combinations of two primes (he would know such numbers as they have only a unique product). *S* knew *P* didn't know the numbers, so the sum also mustn't be a sum of two primes (if the sum could be written as a prime plus prime, *S* couldn't have known that *P* didn't know the numbers, the numbers may have been those two primes and *P* would have known them). This means you can cross out all such numbers -- these are all bottom-left-to-top-right diagonals that go through at least one already crossed out number (combination of primes), as these diagonal have constant sum. Now *P* has a table like this with relatively few numbers left -- if he now leaves in only the numbers that make the product he knows, he'll very likely be left with only one combination of numbers -- there are still many combinations like this, but only the situation when the numbers are set to be 4 and 13 allows *S* to also deduce the numbers after *P* declares he knows the numbers -- this is because *S* knows the combination lies on one specific constant-sum diagonal and 4-13 lie on the only diagonal that in this situation has a unique product within the reduced table. So with some other combinations *P* could deduce the numbers too, but only with 4-13 *S* can finally say he knows them too. 32.

Well, firstly LRS by [anarchist](anarchism.md) principles avoids establishing a centralized community with things such as platforms, senior members, moderators, bureaucracy, codified rules etc. Every nice thing that went this way turned to shit once it became more popular and grew, corruption always appears and prevails (see [Wikipedia](wikipedia.md), [GNU](gnu.md)/FSF, [Linux](linux.md) etc.). So we rather aim for a community of decentralized, loosely associated individuals and small entities with greatly overlapping sets of values rather than any organizations etc. So rather think something like many people with their own websites referring and linking to each other.

Imagine people stop engaging in marketing, market speculation and investing, bureaucracy, public relations, law (copyrights, patents, property laws, taxes, ...), economics, military, meaningless technology (DRM, spyware, cryptocurrency, viruses and antiviruses, ...), artificial meaningless fashion, drug abuse business, organizing political parties, campaigns, unions, counter unions, cartels, strikes, and so on and so forth (this of course doesn't mean hobbies and art should disappear, just unnecessary industries). We will gain millions of people who can help achieve abundance, land that can be used to produce food and build houses to live in (as opposed to skyscrapers, unnecessary factories, parking lots etc.), and we will let go of the immense burden of bullshit business (millions of unnecessary workplaces having to be maintained, millions of people having to commute by car daily, communicate, organize, be watched by employers, ...). People will get healthier, more rested, cooperative and actually passionate about a common goal, as opposed to depressed (needing psychiatrists and antidepressants), lethargic and hostile to each other. Of course this can't happen over night, probably not even over a decade, but we can make the transition slowly, one step at a time and in the meanwhile use rules based e.g. on the following principle: that which is abundant is unlimited for everyone, that which is scarce is equally divided between all. The question is not whether it's possible, but whether we want to do it. - **How do you think it is realistic to achieve abundance of resources for all?** Nowadays it is easily possible to produce enough resources for everyone, i.e. food, electricity, clothing, buildings to live in etc. -- in fact this has been possible for many decades to centuries now, today all the technology for 99% automated production of most basic resources such as food and electricity is available and well tested, it is just kept in private hands for their sole profit.

- **Isn't your society unnatural?** In many way yes, it's unnatural just as clothes, medicine, computers or humans living over 70 years are unnatural. Civilization by definition means resisting the cruelness of nature, however our proposed society is to live as much as possible in harmony with the nature and is much more natural than our current society which e.g. pushes sleep deprivation, high consumption of antidepressants, eating disorders, addiction to social networks and so on. - **Isn't your society unnatural?** In many way yes, it's unnatural just as clothes, medicine, computers or humans living over 70 years are unnatural.

- **Won't people get bored? What will motivate people? If they have everything why would they even get out of bed? Haven't you seen the mouse utopia experiments?** It is a mistake to think that competition and the necessity of making living is the only or even the main driving force of human behavior and creativity (on the contrary, it is usually what makes people commit suicides, i.e. lose the will to live). Human curiosity, playfulness, the joy of collaboration, boredom, sense of altruism, socialization, seeking of life meaning and recognition and many other forces drive our behavior. Ask yourself: why do people have hobbies when no one is forcing them to it? Why don't you bore yourself to death in your spare time? Why don't rich people who literally don't have to work bore themselves to death? Why doesn't your pet dog that's not forced to hunt for food bore himself to death? Maslow's hierarchy of needs tells us that once people fulfill basic needs such as that for obtaining food, they naturally start to pursue higher ones such as that for socializing or doing science or art. Unlike rats in small cages people show interests in seeking satisfaction of higher needs than just food and sex, even those that aren't scientist try to do things such as sports, photography, woodwork or gardening, just for the sake of it. It's not that there would be a lack challenges in our society, just that we wouldn't force arbitrary challenges on people. - **Won't people get bored? What will motivate people?

- **Why are you [defeatist](defeatism.md)? Don't you think it's just pointless trying to achieve something while believing you already failed?** Firstly being defeated doesn't mean disappearing completely, we know we will fail but we'll leave a seed of something that can't eventually be stopped from growing: LRS is extremely ahead of its time -- not by 50 years or 100 years, but more like several thousand years, maybe millions. Monkeys aim to prevail during their life time and by getting at the top of some kind of mountain or social pyramid, by hoarding X wealth, passing some law, creating some kind of country or whatever -- that's completely worthless animal behavior, we aim to achieve something truly significant and good instead which will take longer than our lifetime and will require behaving without self interest and [competition](competition.md). Just like abacus was the very first step towards inventing today's [computers](computer.md), LRS is in this sense the very first step to inventing a truly good society. It is first by completely letting go of all [bullshit](bullshit.md), every single one, including things like "winner mentality", which is why there are almost no supporters, everyone [fails](fail_ab.md) by keeping to the old ways at least in some points. We aim for truth and good, not for winning -- giving up the goal of winning makes us able to take the moral decision in situations when we have to choose between winning and behaving correctly.
- **Without violence, how will you prevent capitalists from continuing capitalism?** As also stated e.g. in the [Trash Magic](trash_magic.md) manifesto, we can simply destroy the economy by refusing to participate in it -- a capitalist cannot sell a thing that's abundant, available everywhere for free, he can't sell services if those services are provided for free. Capitalism is depending on the fact that those who it abuses have nowhere to run away to, once enough of us start building such place and provide a bette place to live, suddenly more people will leave the capitalist system and even if some capitalists remain, they won't be able to do anything, economy won't work anymore. - **Without violence, how will you prevent capitalists from continuing capitalism?** As also stated e.g. in the [Trash Magic](trash_magic.md) manifesto, we can simply destroy the economy by refusing to participate in it -- a capitalist cannot sell a thing that's abundant, available everywhere for free, he can't sell services if those services are provided for free.

- **If you say it's possible, why wasn't it done before?** Firstly big and small scale communities working on [anarchist](anarchism.md), [communist](communism.md) and peaceful principles have existed for a long time in environments that allow it, e.g. those that have abundance of resources. Globally society couldn't reach this state because only until recently we lacked the technology to provide such an ideal environment globally or even on a scale of a whole country, i.e. only until recently we have been forced by the nature to compete for basic resources such as food and space to live. However with computers, factories, high level of automation and other technology and knowledge we posses, we now have, for the first time in history, the capability to establish an environment with abundance of resources for everyone on the planet. Nowadays only social inertia in the form of [capitalism](capitalism.md) is ARTIFICIALLY keeping scarcity and social competition in place -- getting rid of this obsolete system is now needed to allow establishment of our ideal society. Part of the answer to this question may also be that reaching such an advanced state of society requires long development, technological, cultural and intellectual, just as many other things (things like abolishment of death sentence or even accepting the existence of irrational numbers all required a long time of cultural development). - **If you say it's possible, why wasn't it done before?** Firstly big and small scale communities working on [anarchist](anarchism.md), [communist](communism.md) and peaceful principles have existed for a long time in environments that allow it, e.g. those that have abundance of resources.

- **How will you make people work?** We won't, in an ideal society people don't have to work, all work is done by machines -- that's the point of creating machines in the first place. In practice there may in a foreseeable future be the need for small amounts of human work such as overlooking the machines, but the amount of work can be so small that volunteers will easily handle it -- especially with people having no burden of working day jobs there should be no shortage of volunteers. Remember that by abandoning the current system 99% of "bullshit work" (marketing, lawyers, bureaucracy, fashion, ...) will disappear. - **How will you make people work?** We won't, in an ideal society people don't have to work, all work is done by machines -- that's the point of creating machines in the first place.

# Proof
TODO
**Why do we need mathematical proof if something is obvious?** Well, mathematicians need to be most precise and proof enables them to discover absolute truths without any shadow of a doubt (a luxury most other scientists don't have), so they set it as a standard because many things that seem obvious aren't in fact so -- for example numbers 31, 331, 3331, 33331, 333331, 3333331 and 33333331 are all [primes](prime.md) so you might think by this pattern also 333333331 will be a prime, but that's not the case because 333333331 = 19607843 * 17. Sometimes patterns deceive us, mathematicians only take proof for the ultimate solution. But indeed e.g. the industry sometimes accepts even unproven but highly likely conjectures to hold, e.g. that [P doesn't equal NP](p_vs_np.md), simply for economic reasons (the chance of being wrong is very low and profitability of being right is high).

Tangram is a simple, yet greatly amusing old puzzle [game](game.md) in which the player tries to compose a given shape (of which only silhouette is seen) out of given basic geometric shapes such as triangles and squares. It is a rearrangement puzzle. Many thousands of shapes can be created from just a few geometric shapes, some looking like animals, people and man made objects. This kind of puzzles have been known for a long time -- the oldest recorded tangram is Archimedes' box (square divided into 14 pieces), over 2000 years old. In general any such puzzle is called tangram, i.e. it is seen as a family of puzzle games, however tangram may also stand for **modern tangram**, a one with 7 polygons which comes from 18th century China and which then became very popular also in the west and even caused a so called "tangram craze" around the year 1818.
