 The unfair, unethical behavior of corporations is still supposed to be controlled by the [state](state.md), however corporations become stronger and bigger than states, they can manipulate laws by lobbying, financially supporting preferred candidates, brainwashing people via private media and so on. States are the only force left supposed to protect people from this pure evil, but they are too weak; a single organization of relatively few people who are, quite importantly, often corporation managers, won't compete against a plethora of the best warriors selected by the extremely efficient system of free market. States slowly turn to serving corporations, becoming their tools and then slowly dissolve (see how small role the US government already plays). This leads to "[anarcho capitalism](ancap.md)", the worst stage of capitalism where there is no state, no entity supposed to protect the people, there is only one rule and that is the unlimited rule of the strongest.
 
-Here the strongest corporation takes over the world and starts becoming the higher order organism of the whole Earth, [capitalist singularity](capitalist_singularity.md) has been reached. The world corporation doesn't have to pretend anything at this point, it can simply hire an army, it can use physical force, chemical weapons, torture, unlimited surveillance, anything to achieve further seize of remaining bits of power and resources. We can only guess what will happen here, a [collapse](collapse.md) due to instability or total destruction of environment is possible, which would at least save the civilization from the horrendous fate of being eternally tortured. If the system survives, humans will be probably genetically engineered to be more submissive, killing any hope of a possible revolt, surveillance chips will be implanted to everyone, reproduction will be controlled precisely and finally perhaps the system will be able, thanks to an advanced [AI](ai.md), to exist and work more efficiently without humans completely, so they will be eliminated. This is how the mankind ends.

+**People will NOT protest or revolt** at this point, they will accept anything that comes and even if they suffer everyday agony and the system is clearly obviously set up for their maximum exploitation, they will do nothing -- in fact they will continue to support the system and make it stronger and they will see more slavery as more freedom; this tendency is already present in [rightists](left_vs_right.md) today. You may ask why, you think that at some point people will have enough and will seize back their power. This won't happen, just as the billions of chicken and pigs daily exploited at factories won't ever revolt -- firstly because the system will have absolute control over people at this point, they will be 100% dependent on the system even if they hate it, they will have proprietary technology as part of their bodies (which they willingly admitted to in the past as part of bigger comfort while ignoring our warnings about loss of freedom), they will be dependent on drugs of the system (called "vaccines" or "medicine"), air that has to be cleaned and is unbreathable anywhere one would want to escape, 100% of communication will be monitored to prevent any spark of revolution etc. Secondly the system will have rewritten [history](history.md) so that people won't see that life used to be better and bearable -- just as today we think we live in the best times of history due to the interpretation of history that was force fed us at schools and by other propaganda, in the future a human in every day agony will think history was even worse, that there is no other option than for him to suffer every day and it's a privilege he can even live that way.

 - *"Capitalism isn't perfect but it's the best system we know."*: complete [bullshit](bullshit.md), capitalism is probably the worst system that there ever was. See this whole article.
 - *"Successful capitalists are the most intelligent people."*: on the contrary, mostly the stupidest people become successful -- success in capitalism depends mostly on luck and lack of moral obstacles, i.e. doing whatever it takes to succeed such as stabbing friends in the back, public lying, exploitation of workers etc. High intelligence is actually a disadvantage in this manner as it makes one see all the negative consequences of his behavior, a smart man sees that by engaging in capitalism he is not just hurting and even killing other people, but even e.g. working towards destruction of art, culture, living environment and possibly life itself. Being a successful businessman in capitalism is like steering a plane full of people, including oneself, towards ground -- only an idiot can do it.

+Problems in each category should follow from easiest to most difficult. The listed solutions may not be the only possible solutions, just one of them.
+
+## General Knowledge
+
+1. What is the difference between [free software](free_software.md) and [open source](open_source.md)?
+
+### Solutions
+
+1. The [free software](free_software.md) and [open source](open_source.md) movements are technically very similar but extremely different in spirit, i.e. while most free software licenses are also open source and vice versa (with small exceptions such as [CC0](cc0.md)), free software is fundamentally about pursuing user freedom and ethics while open source is a later capitalist fork of free software that removes talk about ethics, aims to exploit free licenses for the benefit of business and is therefore unethical.
+
+## Programming
+
+1. Write a [C](c.md) program that prints out all [prime numbers](prime.md) under 1000 as well as the total count of these prime numbers.
+
+### Solutions
+
+1:
+
+```
+// Sieve of Eratosthenes algorithm, one possible way to generate prime numbers
+#include <stdio.h>
+#define N 1000
+
+char primeMap[N];
+
+int main(void)
+{
+  int primeCount = 0;
+
+  for (int i = 0; i < N; ++i)
+    primeMap[i] = 1;
+
+  for (int i = 2; i < N; ++i)
+  {
+    if (primeMap[i])
+    {
+      primeCount++;
+      printf("%d\n",i);
+    }
+
+    int j = i;
+
+    while (1) // mark all multiples of i non-primes
+    {
+      j += i;
+
+      if (j >= N)
+        break;
+
+      primeMap[j] = 0; // can't be a prime

 - **[bit hacks](bit_hack.md)**: Clever manipulations of [bits](bit.md) -- for example it is possible to swap two variable without a temporary variables by using the [xor](xor.md) function. Another simplest example is implementing division by 2 as binary shift by 1 (this hack is used in real life by people for quickly dividing by 10, we just remove the last digit).
 - **[copyleft](copyleft.md)**: A legal hack by [Richard Stallman](rms.md), connected to [free software](free_software.md), working on the basis of the following idea: "If [copyright](copyright.md) lets me put any conditions on my work, I may impose a condition on my work that says that any modified version must not impose any restrictive conditions".
-- **[fast inverse square root](fast_inverse_sqrt.md)**: Famous hack that was used in the [game](game.md) Quake, it [approxmates](approximation.md) a [square root](sqrt.md) of a [floating point](float.md) number by treating it as an integer and bashing it with a [magic constant](magic_constant.md), which is about four times faster than computing the value with the obvious floating point division.
+- **[fast inverse square root](fast_inverse_sqrt.md)**: Famous hack that was used in the [game](game.md) Quake, it [approxmates](approximation.md) an inverse of [square root](sqrt.md) of a [floating point](float.md) number by treating it as an integer and bashing it with a [magic constant](magic_constant.md), which is about four times faster than computing the value with the obvious floating point division.
 - **memory [rape](rape.md) in [C](c.md)**: E.g. instead of doing proper memory allocation with potentially inefficient and bloated `malloc` one may try to do a custom memory allocation without any libraries by abusing allocation on stack -- allocate a variable size array in main, set some global pointer to it and then manage this chunk of memory with your own allocation functions.
-- **actually portable executable** (https://justine.lol/ape.html): Justine Tunney found a way to create an executable format that passes as a valid NATIVE executable on all major systems including [Linux](linux.md), [Windows](windows.md) and [Mac](mac.md), i.e. it is possible to compile a native program (e.g. with [C](c.md)) and then have it natively run on any major OS.

 - **[game of life](game_of_life.md) patterns**: Stable patterns such as glider or even programming game of life in game of life is a nice example of game hacking -- in fact exactly game of life hacking stood at the beginning of hacker culture.
 - **[bytebeat](bytebeat.md)**: A [demoscene](demoscene.md) hack that utilizes integer [overflows](overflow.md) to create rhythm and produce music.
 - Computer [graphics](graphics.md) uses many clever tricks that could possibly be called hacks, e.g. in times when 3D graphics was primitive and didn't allow achieving such effects as mirror reflections easily, some [games](game.md) faked mirrors simply with a hole in the wall behind which the whole mirrored room was placed -- this achieved the same effect as a mirror and didn't require any extra rendering passes or shaders.
