 Beginners similarly often forget breaks in switch statement, which works but usually not as you want -- thankfully compilers warn you about this.
 
+Also `putchar('a')` versus `putchar("a")` ;) Only the first one is correct of course.
+
+**Stdlib API can be [trollish](trolling.md)**, for example the file printing functions: *fprintf* expects the file pointer as first argument while *fputs* expects it as last, so to print hello you can do either `fprintf(file,"hello")` or `fputs("hello",file)` -- naturally this leads to fucking up the order sometimes and doing so even compiles (both arguments are pointers), the running code then crashes.
+
 Watch out for **operator precedence**! C infamously has weird precedence with some special operators, bracket expressions if unsure, or just to increase readability for others. Also nested ifs with elses can get tricky -- again, use curly brackets for clarity in your spaghetti code.
 
 **[Preprocessor](preprocessor.md) can give you headaches** if you use it in overcomplicated ways -- ifdefs and macros are fine, but too many nesting can create real mess that's super hard to debug. It can also quite greatly slow down compilation. Try to keep the preprocessing code simple and flat.

 # Doom
 
-Doom is a legendary video [game](game.md) released in December [1993](1990s.md), perhaps the most famous video game of all time, the game that popularized the [first "person" shooter](first_person_shooter.md) genre and shocked by its at the time extremely advanced [3D](pseudo_3D.md) graphics (yes, **Doom is 3D**) and caused one of the biggest revolutions in video game history. It was made by [Id Software](id_software.md), most notably by [John Carmack](john_carmack.md) (graphics + engine programmer) and [John Romero](john_romero.md) (tool programmer + level designer). Doom is sadly [proprietary](proprietary.md), it was originally distributed as [shareware](shareware.md) (a gratis "demo" was available for playing and sharing with the option to buy a full version). However the game engine was later (1999) released as [free (as in freedom) software](free_software.md) under [GPL](gpl.md) which gave rise to many source [ports](port.md) and "improved" "[modern](modern.md)" engines (which however look like shit, the original looks by far the best, if you want to play Doom use Chocolate Doom or Crispy Doom, avoid anything with GPU rendering).

[Anarch](anarch.md) is an official [LRS](lrs.md) game inspired by Doom, completely in the [public domain](public_domain.md). Doom named a whole generation of so called [doomers](doomer.md).

 4. **password generator**: Make a program which when run outputs randomly generated password (the password must be different each time you run the program of course). The password must be at least 10 characters long, contain at least one decimal digit and one special character.
 5. **average**: Make a program that reads two numbers (you can assume only non-negative integers will be input) and writes out their average (it can be rounded, even to just integer, e.g. 3 and 8 can give 5).
+6. **[Nim](nim.md)**: Implement the simple variant of the game Nim for two human players -- At the beginning there will be 15 matches, players take turn, in each turn a player can take 1, 2 or 3 matches. That who takes the last one loses. The game has to show the number of matches as a numeral and also as some kind of symbols, for example: `|||||||||||||||`. Players have to input `1`, `2` or `3` to play their turn, on wrong input the game has to report error and ask again. At the end winner must be shown. Thumbs up for randomly setting the initial number of matches between 10 and 15.

You may choose to read the input program either from standard input or from a file (the file may have some hardcoded name, e.g. your program will just look for a file named `program.bf` in the same directory). If the brainfuck program is invalid or runtime error occurs in it, you may just write out `error` and halt your interpreter. Thumbs up for making the interpreter nicer, e.g. allowing to pass input file name as a CLI argument, reporting more details about errors (e.g. its position in source code) and so on.
-5. **[game of life](game_of_life.md)**: Make a program that simulates game of life on a finite *N * N* grid, with wrapping space (i.e. a cell on the very left of the grid is considered a neighbor of the cell on the very right in the same row, same thing with top and bottom). Make *N* configurable at least as a compile time option, draw the world as [ASCII art](ascii_art.md) to terminal, make the user step forward by pressing some key.

The functionality must be at least on the level of the most plain physical calculators, i.e. it doesn't have to parse whole complex expressions, but it should be able to add, subtract, multiply, divide and find square roots. Results can be approximate, showing just 3 fractional decimal digits.

Each time it is run, it will generate generally a different text that consists of 10 paragraphs; each paragraph ends with newline and consists of 5 to 10 sentences; each sentence consists of 3 to 10 words, starts with capital letter (other letters are lowercase) and ends with period. After period there is space except when it's the last period in a paragraph. Words are selected randomly from some set of words you define.

Assume just ASCII characters on input (encrypted output can be non-ASCII). You can just choose and hardcode some specific *N* but thumbs up for allowing to set any *N*.

 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. **[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.
+11. **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++.

 9. **3D [path tracer](path_tracing.md) without [floating point](float.md)**: Write a path tracer (NOT a mere [ray tracer](ray_tracing.md)) without using floating point. It can only produce static images that may just be saved to a file in some simple format (no need to draw real time animation to the screen). It must be possible to position and rotate the camera arbitrarily and to set its field of view. It has to support several shapes of objects in the scene: at least a sphere, plane and cylinder, and it must support transparent objects. Thumbs up for supporting polygonal models, depth of field and loading scene description from a file.
 10. **[gopher](gopher.md) fulltext search engine**: Create a whole search engine (with crawler, index creator, user frontend, ...) for the gopher network. It can store its database just to flat files (no need to use SQL or something like that). It has to allow at least very basic fulltext search, i.e. about each gopher site you'll have to remember which words it contains (and possibly their count), so that if the user searched e.g. for `cats dogs`, you'll give him sites that contain both of these words somewhere in their text -- offer options to search either for sites containing all searched words or just some of them. Besides this you can make simplifications (ignore case, don't support Unicode, special characters etc.). Thumbs up for additional features like creating a graphical map of the crawled gopherspace along the way.
+11. **[Jpeg](jpg.md) clone**: Create a usable format for photo images with lossy [compression](compression.md), similar to [Jpeg](jpg.md), that achieves good compression ratio and allows setting compression level, including setting compression level 0 (when it will only apply lossless compression). The format doesn't have to store any metadata, it's enough if it holds a 24 bit RGB bitmap of arbitrary resolution. For compression it must do at least following: separating the color and intensity channel and subsampling the color channel (see e.g. [YCbCr](ycbcr.md)), then converting the image to frequency domain (probably with [discrete cosine transformation](dct.md)) and quantizing the high frequencies, and then applying at least some lossless compression (RLE or Huffman coding or something). You can't use any libraries to do the described things (e.g. DCT, color conversion etc.), do it all yourself. The program, with medium compression level set, has to beat lz4 at compressing photos at least 90% times (in theory it should win always but we'll give you some margin if you fuck something up).

 1. Though legally similar (but not identical), free software is a movement based on ethics and pursuing freedom for the software user, open source is evil business movement that avoids talking about ethics, it was forked from free software and is solely focused on exploiting free software licenses for making profit.

-3. The mirror doesn't flip the text, you flipped it by pointing it at the mirror -- you most likely flipped it horizontally so that's how you see it in the mirror, but you could as well have flipped it vertically; then the text would be flipped vertically in the mirror.
+3. The mirror doesn't really flip the text -- what's left/right in front of it is also left/right in it. It is you who flipped the text when you pointed it at the mirror -- you most likely flipped it horizontally so that's how you see it in the mirror, but you could as well have flipped it vertically; then the text would be flipped vertically in the mirror.
 4. Modulo bias happens when the random number generator's range is non-divisible by our desired range that we enforce with modulo operator -- with shown approach some numbers then have higher probability of being generated than others. For example if rand() here return numbers from 0 to 1023, there is only one way to get 999 (999 % 1000) but two ways to get 0 (0 % 1000 and 1000 % 1000), i.e. 0 is more likely to be generated. Common approach to reducing this effect is to repeatedly generate numbers until we get one falling into the "fair" range (this is not guaranteed to end so we should limit the maximum number of attempts).
 5. The relationship is commonly described like this: information is interpreted data. I.e. data is just a sequence of symbols, information is the knowledge we extract from it.
 6. The probability of program breaking is 1 minus probability of it not breaking. For a program to NOT break during one year, all libraries have to stay unchanged (probability 0.95 for each one): that's 0.95 * 0.95 * 0.95 * ... = 0.95^10. Similarly the probability of it not breaking during 5 years is (0.95^10)^5, so the probability of the program breaking in 5 years is around 92%.

Because they need to make living or because they simply WANT to make a lot of money and so they do what the system wants them to do. Education in technology (and generally just being exposed to corporate propaganda since birth) is kind of a trap: it teaches you to embrace complexity and when you realize it's not a good thing, it is too late, you already need to pay your student loan, your rent, your mortgage, and the only thing they want you to do is to keep this complexity cult rolling. So people just do what they need to do and many of them just psychologically make themselves believe something they subconsciously know isn't right because that makes their everyday life easier to live. "Everyone does it so it can't be bad, better not even bother thinking about it too much". It's difficult doing something every day that you think is wrong, so you make yourself believe it's right.

 Instead of the word *race* the politically correct camp uses words such as *ethnicity* -- it's funny, sometimes they say no such thing as race exists but other times they simply have to operate with the fact that people are genetically diverse, e.g. when they accuse others of [racism](racism.md) or point out statistics that benefit them ("black people are paid less!"), as existence of discrimination based on differences between people necessarily implies the existence of differences between people -- so here they try to substitute the word *race* for a different word so as to make their self-contradiction less obvious. Anyway, it doesn't [work](work.md) :) Races indeed do exit, no matter what we call them.

 YouTube (also JewTube { Lol jewtube.com actually exists. ~drummyfish} or just YT) is a huge, [censored](censorship.md) [proprietary](proprietary.md) [capitalist](capitalism.md) video [consuming](consumerism.md) "website"/platform, since 2006 seized by the [Google](google.md) terrorist organization. It has become the monopoly "video content platform", everyone uploads his videos there and so everyone is forced to use that shitty site from time to time to view some tutorial or whatnot. YouTube is based on content consumerism, aggressive predatory marketing, [copyright trolling](copyright_troll.md), propaganda and general abuse of its [useds](used.md) -- it is financed from surveillance-powered ads as well as sponsor propaganda inserted into videos. Alternatives to YouTube, such as [bitchute](bitchute.md), the "rightist" YouTube, never really caught on very much -- YouTube is sadly synonymous with online videos just as Google is synonymous with searching the web. This is of course extremely, extremely, extremely, extremely bad.
 
+Just one of countless damages YouTube has done to society is establishing videos as standard medium of any form of communication and information storage -- back in the day Internet was mostly text-based, sometimes there was an image or video of course, but only when needed. Since YouTube's rise to fame a lot of information has just moved to videos, even that which suffer by this format, e.g. books, announcements, notes, presentations, tutorials, pure audio and so on. All of this [bloat](bloat.md) of course makes the information hard to index and search, store, process, view on weak devices, it wastes enormous amounts of bandwidth, computing power and so forth. Thanks YouTube.
+
 { https://www.vidlii.com seems alright though, at least as a curiosity. Anyway if you need to watch YouTube, do not use their website, it's shitty as hell and you will die of ad cancer, rather use something like invidious or youtube-dl. Here is an **awesome hack I discovered to search only old videos on youtube**! The new shit is just unwatchable, there's clickbait, sponsors, propaganda, SJW shit everywhere, thankfully you can just exclude any year from the search with with "-year" (at least for now), for example: https://yewtu.be/search?q=free+software+-2023+-2022+-2021+-2020+-2019+-2018+-2017+-2016+-2015+-2014+-2013+-2012+-2011+-2010+-2009&page=1&date=none&type=video&duration=none&sort=relevance. Enjoy. ~drummyfish }
 
 **What are the alternatives to YouTube?** We'll only leave a brief paragraph here for wannabe YouTube alternatives come and go faster than a [zoomer](zoomer.md) changes genders. Best alternative to watching videos is reading [books](books.md) or watching clouds in the sky, but we'll stick to "watching videos on the Internet" here. Also bear in mind that if you have to watch YouTube, use alternative YouTube [frontends](frontend.md), which are normally [FOSS](foss.md) -- e.g. Invidious, piped, HookTube or FreeTube -- these let you access YouTube's videos via less [bloated](bloat.md) and more "privacy-friendly" interface, also filtering out ads and so on, more hardcore people use [CLI](cli.md) tools such as [youtube-dl](youtube_dl.md) to directy download the videos and watch them in native players. Likely the most notable [FOSS](foss.md) alternative to YouTube is **[PeerTube](peertube.md)**, a [federated](federation.md) [P2P](p2p.md) video platform, however for intended use it requires [JavaScript](javascript.md) (there is a way to download videos without JS but it's discouraged) and there are other issues that make it unusable ([SJW](sjw.md) censorship, videos load extremely slowly, ...). If you use PeerTube, don't use the lesbian instances, look up the uncensored ones. Mainstream proprietary alternative to YouTube is Vimeo, Bitchute is the "rightist" YouTube alternative (quite shitty TBH). [Internet Archive](internet_archive.md) has many video, especially old ones -- this is quite nice alternative. Vidlii is proprietary but oldschool site that tries to replicate old YouTube for the nostalgia, it has its own videos and small, dedicated community and very low censorship, it is pretty nice, with 360p videos and all; a site very similar to Vidlii it Bitview.
