Capitalism is the worst (not only) economic system we've yet seen in the history,^[source](logic.md) literally based on pure greed and artificially sustained conflict between people (so called [competition](competition.md)), abandoning all morals and putting money and profit (so called [capital](capital.md)) above everything else including preservation of life itself, capitalism fuels the worst in people and forces them to compete and suffer for basic resources, even in a world where abundance of resources is already possible to achieve. Capitalism goes against progress (see e.g. [antivirus paradox](antivirus_paradox.md)), [good technology](lrs.md), freedom, it supports immense waste of resources, wars, abuse of people, destruction of environment, decline of morals, invention of [bullshit](bullshit.md) (bullshit jobs, bullshit laws, ...), [torture](marketing.md) of people and animals and much more. Nevertheless, it's been truthfully stated that "it is now easier to imagine the end of all life than any substantial change in capitalism."

# Crime Against Economy
Crime against [economy](economy.md) refers to any [bullshit](bullshit.md) "crime" invented by [capitalism](capitalism.md) that is deemed "hurt economy", the new god of society. In the current dystopian society where money has replaced God, worshiping economy is the new religion; to satisfy economy human and animal lives are sacrificed just as such sacrifices used to be made to please the gods of ancient times.
Examples of crimes against economy include:
- Fixing purposefully broken technology, e.g. removing [DRM](drm.md).
- Shielding oneself from marketing torture and refusing to [consume](consumerism.md), e.g. by using [adblocks](adblock.md).
- Burning money.
- Doing literally anything that could destabilize economy such as simply giving away too many things for free or for very low prices.
- Sharing useful information with other people which is called a "theft" of [intellectual property](intellectual_property.md), "[piracy](piracy.md)" etc.
- Taking basic natural resources from monstrously rich corporations who declare to own natural resources and deny access to them. E.g. printing money or physically taking goods from corporations without paying is declared a crime.
- Destroying [ads](ads.md) and so sparing other of suffering.
- Encouraging others to commit crimes against economy. Indeed we highly encourage everyone to commit these crimes.
- Revealing certain truths about rich people, corporations, their products or states, so called [whistleblowing](whistleblowing.md), [antivaxxing](antivax.md) etc.

# Digital Signature # Digital Signature
Digital signature is a method of mathematically (with [cryptographical](cryptography.md) algorithms) proving that, with a high probability, a digital message or document has been produced by a specific sender, i.e. it is something aka traditional signature which gives a "proof" that something has been written by a specific person.

It works on the basis of [asymmetric cryptography](asymmetric_cryptography.md): the signature of a message is a pair of a public key and a number (the signature) which can only have been produced by the owner of the private key associated with the public key. This signature is dependent on the message data itself, i.e. if the message is modified, the signature will no longer be valid, preventing anyone who doesn't posses the private key from modifying the message. The signature number can for example be a [hash](hash.md) of the message decoded with the private key -- anyone can check that the signature encoded with the public key gives the document hash, proving that whoever computed the signature number must have possessed the private key.

# Quine
Quine is a nonempty [program](program.md) which prints its own source code. It takes no input, just prints out the source code when run (without [cheating](cheating.md) such as reading the source code file). Quine is basically a self-replicating program, just as [in real world](irl.md) we may construct robots capable of creating copies of themselves (afterall we humans are such robots). The name *quine* refers to the philosopher Willard Quine and his paradox that shows a structure similar to self-replicating programs. Quine is one of the standard/[fun](fun.md)/[interesting](interesting.md) programs such as [hello world](hello_world.md), [99 bottles of beer](99_bottles.md) or [fizzbuzz](fizzbuzz.md).
Quine can be written in any [Turing complete](turing_completeness.md) [language](programming_language.md), the challenge is in the [self reference](self_reference.md) -- normally we cannot just single-line print a string literal containing the source because that string literal would have to contain itself, making it [infinite](infinity.md) in length. The idea commonly used to solve this problem is following:
1. On first line start a definition of string *S*, later copy-paste to it the string on the second line.
2. On second line put a command that prints the first line, assigning to *S* the string in *S* itself, and then prints *S* (the second line itself).
This is a quine in [C](c.md):
```
#include <stdio.h>
char s[] = "#include <stdio.h>%cchar s[] = %c%s%c;%cint main(void) { printf(s,10,34,s,34,10,10); return 0; }";
int main(void) { printf(s,10,34,s,34,10,10); return 0; }
```
This is a quine in [Python](python.md):
```
s="print(str().join([chr(115),chr(61),chr(34)]) + s + str().join([chr(34),chr(10)]) + s)"
print(str().join([chr(115),chr(61),chr(34)]) + s + str().join([chr(34),chr(10)]) + s)
```

# Trusting Trust
In computer [security](security.md) *trusting trust* refers to the observation (and a type of attack exploiting it) that one cannot trust the technology he didn't create 100% from the ground up; for example even a completely [free](free_software.md) compiler such as [gcc](gcc.md) with verifiably non-malicious code, which has been compiled by itself and which is running on 100% free and non-malicious hardware may still contain malicious features if a non-trusted technology was ever involved in the creation of such compiler in the past, because such malicious technology may have inserted a self-replicating malicious code that's hiding and propagating only in the executable binaries. It seemed like this kind of attack was extremely hard to detect and counter, but a method for doing exactly that was presented in 2009 in a PhD thesis called *Fully Countering Trusting Trust through Diverse Double-Compiling*. The problem was introduced in [Ken Thompson's](ken_thompson.md) 1984 paper called *Reflections on Trusting Trust*.
**Example**: imagine free software has just been invented and there are no free [C](c.md) compilers yet, only a proprietary (potentially malicious) C compiler *propC*. We decide to write the first ever free C compiler called *freeC*, in C. *freeC* code won't contain any malicious features, of course. Once we've written *freeC*, we have to compile it with something and the only available compiler is the proprietary one, *propC*. So we have to compile *freeC* with *propC* -- doing this, even if *freeC* source code is completely non-malicious, *propC* may sneakily insert malicious code (e.g. a [backdoor](backdoor.md) or [telemetry](telemetry.md)) to *freeC* binary it generates, and it may also insert a self-replicating malicious code into it that will keep replicating into anything this malicious *freeC* binary will compile. Then even if we compile *freeC* with the (infected) *freeC* binary, the malicious self-replicating feature will stay, no matter how many times we recompile *freeC* by itself. Keep in mind this principle may be used even on very low levels such as that of [assembly](assembly.md) compilers, and it may be extremely difficult to detect.
**For a little retarded people**: we can perhaps imagine this with robots creating other robots. Let's say we create plans for a completely nice, non-malicious, well behaved servant robot that can replicate itself (create new nice behaving robots). However someone has to make the first robot -- if we let some potentially evil robot make the first "nice" robot according to our plans, the malicious robot can add a little malicious feature to this othrwise "nice" robot, e.g. that he will spy on its owner, and he can also make that "nice" robot make pass this feature to other robots he makes. So unless we make our first nice robot by hand, it's very hard to know whether our nice robots don't in fact posses malicious features.
