-Comment is part of computer code that doesn't affect how the code is interpreted by the computer and is intended to hold information for humans that read the code (even though comments can sometimes contain additional information for computers such as metadata and autodocumentation information). There are comments in basically all [programming languages](programming_language.md), they usually start with `//`, `#`, `/*` and similar symbols, sometimes parts of code that don't fit the language syntax are ignored and as such can be used for comments.

+While yes, you should write nice, [self documenting](self_documentation.md) code, **you should comment you source code** as well. General tips on commenting:
 
 - ALWAYS put a **global file comment** at the top of a file to make it [self-contained](self_contained.md). It should include:
   - **Description of what the file actually does.** This is extremely important for [readability](readability.md), documentation and quick orientation. If a new programmer comes looking for a specific part of the code, he may waste hours on searching the wrong files just because the idiotic author couldn't be bothered to include fucking three sentences at the start of the file. [Modern](modern.md) program just don't fucking do this anymore, this is just [shit](shit.md).
   - [License](license.md)/[waiver](waiver.md), either full text or link. Even if your repo contains a global license (which it should), it's good for the file to carry the license because the file may just be copy pasted on its own into some other project and then it will appear as having no license.
   - **Name/nick of the author(s)** and roughly the date of creation (year is enough). This firstly helps legally assess [copyright](copyright.md) (who and for how long holds the copyright) and secondly helps others contact the author in case of encountering something weird in the code.
 - Comment specific blocks of code with **keywords** -- this will help searching the code with tools like [grep](grep.md). E.g. in game's code add comment `// player: shoot, fire` to the part of code that handles player's shooting so that someone searching for any one of these two words will be directed here.
+- Be brief, don't write poetry, too much text and pompous style will make it less readable.
 - Functions (maybe with some exceptions like trivial one-liners) should come with a comment documenting:
   - **Behavior** of the function, what it does and also how it does that (Is the function slow? Is it safe? Does it perform checks of arguments? Does it have [side effects](side_effect.md)? How are errors handled? ...).
   - **Meaning of all arguments** and if needed their possible values.
   - **Return value meaning**.
 - You may decide to use comment format of some [autodoc](autodoc.md) system such as [doxygen](doxygen.md) -- it costs nothing and helps firstly unify the style of your comments and secondly, obviously, generate automatic documentation of your code, as well as possibly automatically process it in other ways.
 - TODO: moar

+Way too many comments are sometimes considered bad, there shouldn't be more comments than code, unless maybe in some super complex [assembly](assembly.md) program :) There also seem to be controversial opinions around about comments being essentially [harmful](harmful.md) at least to a degree, for example [Jonathan Blow](jonathan_blow.md) said that "comments are code that never runs and code that never runs has bugs" { I think that's a bit misleading -- comments are never run by a computer but they are run by the brain, a kind of neural network that is tolerant to many bugs, so a comment that's been read by a few people who didn't find anything wrong about it is kind of tested. Besides that by definition the purpose of a comment is not to define algorithms, comments aren't code or at least shouldn't take such role, they're there for other purposes, e.g. declaring intent, putting a reference to something and so on. ~drummyfish }.

 # Czechia
 
-Czechia, or Czech Republic, is a small country in the middle of [Europe](europe.md), it's one of the worst countries in the world. It split from Czechoslovakia in 1993, its capital is Prague, it has about 78 square kilometers and population of 11 millions. In the past the country wasn't so bad, there was a good tradition of [socialism](socialism.md) so people had complete social security, education was completely free, everyone could afford food, there were very few ads in the media and generally people were quite happy, everyone would get healthcare and retirement pension; there was also quite diverse culture of different villages with their own language dialects and traditions, there was zero crime, no one ever heard of guns or violence there, there was no fear, and art was also somewhat nice, especially music, movies and movie dubbing. All of this disappeared swiftly once the country adopted [capitalism](capitalism.md) and [US](usa.md) culture after the so called *Velvet revolution* at the beginning of 1990s. Recently people were again made to vote -- the choices were to either make everything more shitty or to make things better. They voted to make everything shittier, so inflation is now skyrocketing, people are freezing in winter, TV is unwatchable, food is luxury, let alone things like houses, nothing works, everyone is enslaved, retirement age was postponed to something like 100 years of age plus you must have worked for about 80 years or something (this gets increased every year), ads torture you everywhere, there is no art anymore, health insurance payment is mandatory but you still have to pay for healthcare, but you won't find a doctor anyway, there are no doctors anymore (everyone went to do [marketing](marketing.md)). The country is only famous for its tradition of drinking a lot of beer. Czech people are mostly described by foreigners as cold, unfriendly, rude and ugly. One of the most famous politicians is a Czech Neonazi who's actually Japanese. Czechia has no historical, political or cultural significance.

 Czech [language](human_language.md) is unironically **the worst language** that there ever was or ever will be. Firstly it sounds horrible, secondly it's the hardest language on Earth, it has seven cases and declinations and things that make every word have like 20 distinct forms (e.g. "to teach": ucit, ucil, ucila, ucilo, ucili jsme, ucili jste, ucili, ucim, ucis, uci, ucime, ucite, budu ucit, budes ucit, ucil bych, ucila bys, ucili bychom, ... ; "dog": pes, psa, psu, psovi, psi, pse, psy, psum, psech, pejsek, pejsku, pejskovi, pejsky, ... ; "cat": kocka, kocce, kocku, kockou, kocky, kockam, kocicka, kocicce, kocicku, kocickami, ...), NOT EVEN such essential things as forming plural or calling someone are simple at all (e.g. word/plural/vocative: pes/psi/pse, kocka/kocky/kocko, dum/domy/dome, stroj/stroje/stroji, ... do you see any pattern? probably not) PLUS, according to Guinness World Record Book, it also contains the most difficult sound to pronounce (that *r* with arrow above it, great many natives actually can't say it, it's called *rackovani*), there are so many irregularities that children spend whole years at school just hardcore memorizing when to write *y* versus *i* (which are pronounced completely the same, you just have to know which one to write because why not), also for example commas and capitalization of words have strict, extremely difficult rules that again have to be memorized. AND all this effort is for nothing, it doesn't make a slightest sense to learn the language because no one excepts a few idiots in middle of Europe speak it (and not even they speak it well), you will literally hear it nowhere else. So that's another thing.
 
-Czechia had the worst presidents of every country, even in comparison with African shitholes and so on. Havel, the only president who came before capitalism, was alright, after him only absolute retards came, every one was much worse than all the rest combined (that's mathematically impossible but they still managed to do it). For example Zeman was the worst retard in the whole country so he got elected, he looked like Vogon from Hitchhiker's Guide to Galaxy except worse, was constantly drunk, rude, had to be carried around like a little baby by his bodyguards because he couldn't walk straight, he almost threw up on national crown jewels and his most famous moment was when he tried to demonstrate his knowledge of [English](english.md) by explaining to some reporter the meaning of the word "pussy" while getting the pronunciation completely wrong. Klaus was a 10 [IQ](iq.md) capitalist thief who, despite making millions as a president, was stealing pencils while being filmed on camera. You can't make this shit up. The current president is a narcissist professional murderer and war promoter.

 The greatest Czech was Jara Cimrman, a fictional genius whom the people made up to have someone to look up to. The history of the country is also completely made up, it was crafted to serve nationalism, to justify things like separatism and murdering Germans after the war and also to destroy the country etc.

 - A project is considered completed only if you REALLY complete all of its requirements! It's not enough to say "mmm, I could do this if I wanted" -- no, you have to REALLY DO IT for it to count. If the requirement is to make a complete game, a buggy demo doesn't count. Also if you just use some cheat, use 100 libraries to do everything for you, you know you didn't really complete it :) If it's obvious implementing something is part of the challenge (for example collision detection in physics engine), you cannot use a library for it, you have to do it yourself. Just be honest with yourself.
 - You CANNOT award yourself partial points, i.e. if you meet 90% of requirements for some project, you CANNOT give yourself 90% points for it, not even one point. Complete it 100%, then get 100% points. Again, it doesn't count to say "mmm, I could finish this if I wanted" -- no, until you finish it it's not finished. This is part of the challenge and insisting on it also makes you potentially make a nice, tidy program that will increase good in the world ;)
 - You may reuse your own code without it counting as third party library, i.e. if you write 3D renderer in one project, you can use it in writing 3D game as another project, with it counting as if you wrote everything from scratch just for that project.

 3. **[gopher](gopher.md) browser**: Write interactive gopher browser -- it can be a purely [command line](cli.md) browser. It has to be able to follow links and go back at least one page. The program must include some basic help and ability to save files to disk.
 4. **simple text [compression](compression.md)**: Write a program that can compress and decompress plain [ASCII](ascii.md) text files using some very simple technique like [run length encoding](rle.md) (RLE) or dictionary methods (you can even use a fixed dictionary, e.g. have a list of common English words that you will represent by some shorter symbols). You can assume input characters will only have 7bit ASCII codes, so you can compress the text also by dropping the 8th unused bit. You don't have to achieve great compression ratio (you can even enlarge some files), but you must pass the following test: take the program's source code, this article's plain text and Wikipedia main page plain text, your program must compress at least two of these to a smaller size (and of course successfully decompress them into identical files). The program must work as a [filter](filter.md), i.e. it mustn't load the whole file into memory or perform multiple passes, it has to use approximately same amount of RAM for input of any size.
 5. **stupid chatbot**: Make an entertaining chatbot that can react to basic sentences like "how are you?", "are you a robot?", "tell me a joke" and so on. It must give a human-like answer to at least 50 different sentences. It has to deal with typos and text variability a little bit (for example multiple spaces in a row or all caps text mustn't confuse it). It must have a mood meter which changes depending on what the partner says -- for example if the bot gets insulted, it gets more angry and starts inserting profanity to responses; on the other hand if it's happy it will insert nice smiley faces etc. The bot also has to remember and use the name of its chat partner if that is brought up. Test the bot by having it chat with itself.
-6. **arbitrary size [rational numbers](rational_number.md)**: Make a library that allows working with arbitrary size rational numbers, i.e. represent each number as a pair of numerator and denominator, the number will be automatically allocating itself as much memory as it needs for storing the two internal values. Negative numbers must be supported too. It mustn't waste too much memory, i.e. whenever it changes, it will try to simplify the fraction and, if possible, decrease its size and allocate less memory. Size of the number will only be limited by amount of RAM your program can use. Furthermore implement these operations with the numbers: converting to/from the language's native numbers (with rounding if necessary), comparisons (equal, greater, greater or equal, smaller, smaller or equal), addition, subtraction, multiplication, division and printing and/or converting the number to string (at least decimal -- if the number has infinitely many fractional digits, just cut the output somewhere).
-7. **image to [ASCII art](ascii_art.md)**: Make a program that takes an RGB bitmap image and renders it with ASCII characters (i.e. prints it out to console). You can support loading the image from just one file format of your choice, possibly something simple like PPM, BMP or Farbfeld. The program must support resizing the image and it must allow to just set one dimension with keeping the aspect ratio. Thumbs up for extra features like setting brightness/contrast and so on.
-8. **educational [sorting](sorting.md) visualization**: Make a program for visualizing sorting algorithms -- it may draw real graphics (either directly to the screen or by outputting animation file) or just render ASCII art graphics, but it has to clearly show what the sorting algorithm is doing, i.e. which elements are being compared, which are swapped and if it makes good sense to highlight something else (like the pivot or already sorted part of the array), you should do it. Implement at least bubble sort, insertion sort, selection sort and quick sort. Also offer benchmark mode in which all algorithms race in sorting the same array (this can be without advanced visualization, just show e.g. number of steps for each).
-9. **3D model of [fractal](fractal.md)**: Make a program that outputs 3D model of either Siepinski triangle or Koch snowflake fractal. The output shall be some simple 3D format like obj or Collada. The model can be primitive, i.e. it can be just flat shape made of triangles which don't have to really be connected, but the program must allow specifying the number of iterations of the fractal (during invocation, e.g. as a CLI flag). Check that the model is correct by opening it in some 3D editor such as Blender.
-10. **[steganography](steganography.md)**: Make a program that hides text strings in either pictures, sounds or another text. The program must be a nice [CLI](cli.md) utility that performs both encoding and decoding -- it will allow the user to specify the string to hide (this string can be simplified to take less space, e.g. it may be converted to all caps, special characters may be removed etc.) and the data in which to embed them. The size of the string that can be encoded will of course be limited by how much space there is in the data, so you can reject or shorten the string if that's the case. The string must NOT be hidden in metadata (i.e. exif tags, file header, after the data, ...), it must be encoded in the useful data itself, i.e. in pixels of the picture, samples of the sound or characters of the text, but it mustn't be apparent that there is something hidden in the data. Use some simple technique, for example in images and sound you can often change the least significant bits without it being noticed, in text you can insert typos, hyphens, replace some periods with semicolons etc. Get creative.
-11. **[sudoku](sudoku.md) solver**: Create a program to which the user somehow passes a sudoku puzzle (in a file, through a CLI flag, interactively... the choice is yours, but passing a new puzzle mustn't require program recompilation) and the program attempts to solve it. It must first employ some basic reasoning, at very least it has to repeatedly try the elimination method, i.e. marking a set of possible values in each empty square and then reducing these sets by crossing out values that can't be in that square because the same value is in its column/row/minisquare -- wherever only one value remains in the set, it is filled in as final; this has to be repeated until no more progress is being made. If you want, you can employ other techniques as well. After this if the puzzle is still not solved, the program will resort to [brute force](brute_force.md) which has to eventually lead to solution (even if it would take too long). If the program finds that the puzzle is unsolvable, it has to report it.
-12. **language recognizer**: Make a program that will be able to learn and then recognize language of text it is given (in theory it should work for any kind of language, be it human or computer language). Specifically the program will first get *N* files, each one representing a different language (e.g. 5 books in different human languages), then it will take some other text and say to which of the initial *N* files it is linguistically most similar. For simplicity assume only plain ASCII files on input (you can just use some Unicode to ASCII utility on all input files). Use some simple [machine learning](machine_learning.md) technique such as some variant of k-NN. It will suffice if for each training example you construct a vector of some nice features, for example {average word length, vowel/consonant ratio, relative frequency of letter A, relative frequency of letter E, ...}, give each component some weight and then just find the nearest neighbour to the tested sample in this feature space (if you want to be more fancy, split the input files into parts so you get more training samples, then try k-NN with some convenient k). You shouldn't and CANNOT use neural networks, and of course you CANNOT use any machine learning library ;) You don't have to achieve great accuracy but your program should likely be able to quite reliably tell e.g. German from C++.
+6. **[minesweeper](minesweeper.md)**: Implement the minesweeper game! It can be a purely command line program if you manage to render it well with ASCII art and make controls usable, but of course you can try making it GUI as well. There must be at least three difficulty levels that differ by board size and number of mines. First click must never land on a mine. The game must show the time it took to complete it, thumbs up for implementing a persistent top 3 score board that's saved to a file.
+7. **arbitrary size [rational numbers](rational_number.md)**: Make a library that allows working with arbitrary size rational numbers, i.e. represent each number as a pair of numerator and denominator, the number will be automatically allocating itself as much memory as it needs for storing the two internal values.

If the program finds that the puzzle is unsolvable, it has to report it.
+13. **language recognizer**: Make a program that will be able to learn and then recognize language of text it is given (in theory it should work for any kind of language, be it human or computer language). Specifically the program will first get *N* files, each one representing a different language (e.g. 5 books in different human languages), then it will take some other text and say to which of the initial *N* files it is linguistically most similar. For simplicity assume only plain ASCII files on input (you can just use some Unicode to ASCII utility on all input files). Use some simple [machine learning](machine_learning.md) technique such as some variant of k-NN. It will suffice if for each training example you construct a vector of some nice features, for example {average word length, vowel/consonant ratio, relative frequency of letter A, relative frequency of letter E, ...}, give each component some weight and then just find the nearest neighbour to the tested sample in this feature space (if you want to be more fancy, split the input files into parts so you get more training samples, then try k-NN with some convenient k). You shouldn't and CANNOT use neural networks, and of course you CANNOT use any machine learning library ;) You don't have to achieve great accuracy but your program should likely be able to quite reliably tell e.g. German from C++.

 20. 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. On the other hand computing shadows uses some method that works with the scene as a whole to compute true shadowing of objects by other objects.
 21. 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.

-23. 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*.
-24. 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.

Marxists promote establishment of temporary **dictatorship** of the proletariat as they see it the only way to ending capitalism. **Marxists are NOT [altruists](altruism.md)**, their desire of communism doesn't come from love of life, they simply see it as a more efficient societal system than capitalism that's a natural and inevitable next step in evolution of society, they see a man as servant of society, **they are obsessed with [work](work.md)** (even preferring to call themselves *workers* rather than *people*; [language matters](name_is_important.md)) and see people who don't share their values as undesirable -- these undesirable people are not only capitalists, but also people who don't want to work, religious people or people who refuse to [fight](fight_culture.md) for their society. They say that ends justify the means and will happily utilize means such as [war](war.md), dictatorship, executions, [censorship](censorship.md), cults of personality and propaganda. We cannot ever stand behind this.

 # Minesweeper
 
-Minesweeper is a simple but entertaining singleplayer puzzle [game](game.md) whose objective is to deduce the locations of all mines hidden in a square grid from certain clues and mark all the mines without detonating any of them. Commonly the game is treated as a [minigame](minigame.md) but can be taken to much higher level for example with [speedrunning](speedrunning.md) or by expanding the concept to create a more complex game. Minesweeper falls under the kind of games highly appreciated by [LRS](lrs.md) perspective -- it's very simple to program and learn but still highly fun to play, it's mathematically [interesting](interesting.md) and can in theory be played even without a [computer](computer.md) (if someone else prepares you the board). Current form of the game seems to have evolved from a 1983 game called *Mined-Out*.
+Minesweeper is a simple but entertaining singleplayer puzzle [game](game.md) whose objective is to deduce locations of all mines hidden in a square grid given certain numeric clues. You will most often see the game treated as a [minigame](minigame.md) but indeed it can be taken to much higher level for example with [speedrunning](speedrunning.md) or by expanding the concept to create a more complex game; as a matter of fact there is a dedicated community around competitive play of the game (see minesweepergame.com, their wiki nicely explains advanced strategies and techniques such as so called "1.5 click"). Minesweeper falls under the kind of games highly appreciated by [LRS](lrs.md) perspective -- it's very simple, easy to program (try it as an [exercise](exercises.md)) and learn but still highly [fun](fun.md) to play, it's mathematically [interesting](interesting.md) (example: the *Minesweeper theorem* states that any given board has the sum of its clue numbers same as that of its complement board) and can in theory be played even without a [computer](computer.md) (if someone else prepares you the board). Current form of the game seems to have evolved from 1980s games such as *Mined-Out* or *Relentless Logic* (which were in turn likely inspired by older games like *Battleships*), later it became popular mainly due to being one of default games that came with [Windows](windows.md).

+*In progress game, `#` are marked mines.*
 
-The **rules** are following: initially a *W* times *H* grid is created and *N* mines are placed on random squares (size of board and number of mines can affect difficulty). All squares are obscured so that the player doesn't see where the mines are. The player can dig on any square by clicking it -- if he clicks on a mine square, it detonates and he loses (here all mines are revealed to him). Implementations typically make it so that the first click can never land on a mine (if it does, the mine is relocated). If the click is on empty square, then this square as well as all other mine-free squares reachable from this square (by walking in 4 principal directions) are revealed as mine-free. All revealed squares have a clue number which says the number of mines in its immediate 8 neighbor squares -- except for squares with clue number 0, all squares have their clue number written on them (often each number has its own color to help with pattern recognition). These clues help the player deduce where the mines are. Player can mark any hidden square with a mine symbol -- once all mine-free squares are revealed, the game is won.

-The game requires deductive thinking -- at least initially when one is learning, later on it turns almost entirely into a pattern recognition game. The patterns are very local and there isn't that many of them, so one learn them quickly. The game however DOES involve a bit of chance and luck, situations may arise where taking a guess is necessary, but these are relatively few and risk can be minimized with clever deduction.

-Some patterns can be seen in the above image. For example a square with clue number *N* which has *N* neighbors mean that all its neighbors have mines -- this is often seen e.g. with 1s near corners (seen in the picture). We can also see at the bottom of the board that the two squares will both clearly contain mines. A more intricate pattern is seen near the square with number 3 -- the mine above it was deduced from the number 2 at its right and the number 1 next to the 2: according to the 2 square there have to be 2 mines somewhere in the 3 squares above it, but it's impossible for one mine to be above the 2 with the other being top-right from the 2 as that would place 2 mines in the area of the square with clue number 1, therefore one of the mines has to be top-left from the square with number 2 (above the square with 3).

programming_language.md

@@ -81,7 +81,7 @@ Now that we have a specification, i.e. the idea, someone has to realize it, i.e.
 
 A new language comes to existence just as other things do -- when there is a reason for it. I.e. if someone feels there is no good language for whatever he's doing or if someone has a brilliant idea and want to write a PhD thesis or if someone smokes too much weed or if a corporation wants to control some software platform etc., a new language may be made. This often happen gradually (again, like with many things), i.e. someone just starts modifying an already existing language -- at first he just makes a few macros, then he starts making a more complex preprocessor, then he sees it's starting to become a new language so he gives it a name and makes it a new language -- such language may at first just be transpiled to another language (often [C](c.md)) and over time it gets its own full compiler. At first a new language is written in some other language, however most languages aim for **[self hosted](self_hosting.md) implementation**, i.e. being written in itself. This is natural and has many advantages -- a language written in itself proves its maturity, it becomes independent and as it itself improves, so does its own compiler. Self hosting a language is one of the greatest milestones in its life -- after this the original implementation in the other language often gets deletes as it would just be a burden to keep [maintaining](maintenance.md) it.
 
-**So can a language be inherently fast, [bloated](bloat.md) etc.?** When we say a language is fast, bloated, memory efficient and so on, we often refer to its implementations because, as mentioned, a language is just an idea which can be implemented in many ways with different priorities and tradeoffs, so just keep in mind that talking about languages like this usually refers to the implementations. But on the other hand yes, a language CAN itself be seen as inherently having a similar property because it's simply such that its implementations more or less have to have this property. A very complicated language just cannot be implemented in a simple, non-bloated way, an extremely high level and flexible language cannot be implemented to be among the fastest -- so referring to language implementations we also a little bit refer to the language itself as an implementation reflects the abstract language's properties. **How to tell if language is bloated?** One can get an idea from several things, e.g. list of features, [paradigm](paradigm.md), size of its implementations, number of implementations, size of the specification, year of creation (newer mostly means more bloat) and so on. However be careful, many of these are just clues, for example small specification may just mean it's vague. Even a small self hosted implementation doesn't have to mean the language is small -- imagine e.g. a language that just does what you write in plain English; such language will have just one line self hosted implementation: "Implement yourself." But to actually [bootstrap](boot.md) the language will be immensely difficult and will require a lot of bloat.
+**So can a language be inherently fast, [bloated](bloat.md), memory efficient etc.?** When we say a language is so and so, we generally refer to its implementations and our experience from practice because, as explained previously, a language in itself is only an idea that can be implemented in many ways with different priorities and tradeoffs, and not only that; even if we choose specific implementations of languages, the matter of [benchmarking](benchmark.md) and comparing them is very complicated because the results will be highly dependent for example on hardware architecture we use (some [ISA](isa.md) have slow branching, lack the divide instruction, some MCUs lack floating point unit etcetc., all of which may bias results heavily to either side) AND on test programs we use (some types of problems may better fit the specialization of one language that will do very well at it while it would do much worse at other types of problems), the way they are written (the problem of choosing idiomatic code vs transliteration, i.e. performance will depend on whether we try to solve the benchmark problem in the way that's natural for the language or the way that's more faithful to the described solution) and what weight we give to each one (i.e. even when using multiple benchmarks, we ultimately have to assign a specific importance to each one). It's a bit like trying to say who the fastest human is -- generally we can pick the top sportsmen in the world but then we're stuck because one will win at sprint while the other one at long distance running and another one at swimming, and if we consider even letting them compete in different clothes, weather conditions and so on, we'll just have to give up. So speaking about languages and their quantitative properties in practice generally means talking about their implementations and practical experience we have. HOWEVER, on the other hand, it does make sense to talk about properties of languages as such as well -- a language CAN itself be seen as inherently having some property if it's defined so that its every implementation has to have this property, at least practically speaking. Dynamic typing for example means the language will be generally slower because operations on variables will inevitably require some extra runtime checks of what's stored in the variable. A very complicated language just cannot be implemented in a simple, non-bloated way, an extremely high level and flexible language cannot be implemented to be among the fastest -- so in the end we also partially speak about languages as such because eventually implementations just reflect the abstract language's properties. **How to tell if a language is bloated?** One can get an idea from several things, e.g. list of features, [paradigm](paradigm.md), size of its implementations, number of implementations, size of the specification, year of creation ([newer](modern.md) mostly means more bloat) and so on. However be careful, many of these are just heuristics, for example small specification may just mean it's vague. Even a small self hosted implementation doesn't have to mean the language is small -- imagine e.g. a language that just does what you write in plain English; such language will have just one line self hosted implementation: "Implement yourself." But to actually [bootstrap](boot.md) the language will be immensely difficult and will require a lot of bloat.
 
 Judging languages may further be complicated by the question of what the language encompasses because some languages are e.g. built on relatively small "pure language" core while relying on a huge library, preprocessor, other embedded languages and/or other tools of the development environment coming with the language -- for example [POSIX shell](posix_shell.md) makes heavy use of separate programs, utilities that should come with the POSIX system. Similarly [Python](python.md) relies on its huge library. So sometimes we have to make it explicitly clear about this.

This is one of the reasons why there has to be a lot of **bureaucracy**, including things such as **locking of articles** and the inability to edit everything. Even if an article can technically be edited by anyone, there are many times people watching and reverting changes on specific articles. So Wikipedia can't fully proclaim it can be "edited by anyone".
 - Wikipedia is **hard to read**. The articles go to great depth and mostly even simple topics are explained with a great deal of highly technical terms so that they can't be well understood by people outside the specific field, even if the topic could be explained simply (Simple English Wikipedia tries to fix this a little bit at least). Editors try to include as much information as possible which too often makes the main point of a topic drown in the blablabla. Wikipedia's style is also very formal and "not [fun](fun.md)" to read, which isn't bad in itself but it just is boring to read. Some alternative encyclopedias such as [Citizendium](citizendium.md) try to offer a more friendly reading style. Back in the day Wikipedia used to be written pretty well, check it out e.g. at https://nostalgia.wikipedia.org.
 - Wikipedia is **not [public domain](public_domain.md)**. It is licensed under [CC-BY-SA](cc_by_sa.md) which is a [free](free_culture.md) license, but has a few burdening conditions. We belive knowledge shouldn't be owned or burdened by any conditions.

 - **Many articles are bought**, there exist companies that offer editing and maintaining certain articles in a way the client desires and of course corporations and politicians take this opportunity -- of course Wikipedia somewhat tries to prevent it but no prevention ever works 100%, so a lot of information on Wikipedia is either highly misleading, untrue, censored or downright fabricated.
