@ -51,7 +51,7 @@ The following is an overview of some most common compression techniques.
|
|||
|
||||
**[Predictor](predictor.md) compression** is based on making a *predictor* that tries to guess following data from previous values (which can be done e.g. in case of pictures, sound or text) and then only storing the difference against such a predicted result. If the predictor is good, we may only store the small amount of the errors it makes.
|
||||
|
||||
A famous family of dictionary compression algorithms are **Lempel-Ziv (LZ)** algorithms -- these two guys first proposed [LZ77](lz77.md) in (1977, sliding window) and ([LZ78](lz78.md), explicitly stored dictionary, 1978). These were a basis for improved/remix algorithms, most notably [LZW](lzw.md) (1984, Welch). Additionally these algorithms are used and combined in other algorithms, most notably [gif](gif.md) and [DEFLATE](deflate.md) (used e.g. in gzip and png).

An approach similar to the predictor may be trying to find some general mathematical [model](model.md) of the data and then just find and store the right parameters of the model. This may for example mean [vectorizing](vector_graphics.md) a bitmap image, i.e. finding geometrical shapes in an image composed of pixels and then only storing the parameters of the shapes -- of course this may not be 100% accurate, but again if we want to preserve the data accurately, we may additionally also store the small amount of errors the model makes. Similar approach is used in [vocoders](vocoder.md) used in cellphones that try to mathematically model human speech (however here the compression is lossy), or in [fractal](fractal.md) compression of images. A nice feature we gain here is the ability to actually "increase the resolution" (or rather generate detail) of the original data -- once we fit a model onto our data, we may use it to tell us values that are not actually present in the data (i.e. we get a fancy [interpolation](interpotation.md)/[extrapolation](extrapolation.md)).

Wikipedia is a non-commercial, [free/open](free_culture.md) censored [pseudoleftist](pseudoleft.md) [online](www.md) [encyclopedia](encyclopedia.md) of general knowledge written mostly by volunteers, running on [free software](free_software.md), allowing approved and politically correct people from the public to edit its content (i.e. being a [wiki](wiki.md)); it is the largest and perhaps most famous encyclopedia created to date. It is licensed under [CC-BY-SA](cc_by_sa.md) and is run by the [nonprofit](nonprofit.md) organization Wikimedia Foundation. It is accessible at https://wikipedia.org. Wikipedia is a mainstream information source and therefore politically censored^1234567891011121314151617181920.

WARNING: **DO NOT DONATE TO WIKIPEDIA** as the donations aren't used so much for running the servers but rather for their political activities (which are furthermore [unethical](pseudoleft.md)). See https://lunduke.locals.com/post/4458111/the-wiki-piggy-bank.

{ Lol I'm blocked at Wikipedia now, reason being I linked to my personal website from my userpage where I expressed unpopular opinions :D ~drummyfish }

Shortly after the project started in 2001, wikipedia used to be a great project -- it was very similar to how LRS wiki looks right now; it was relatively unbiased, objective, well readable and used plain HTML and ASCII art (see it as https://nostalgia.wikipedia.org/wiki/HomePage), however over the years it got corrupt and by 2020s it has become a political battleground and kind of a [politically correct](political_correctness.md) [joke](jokes.md). A tragic and dangerous joke at that. It's still useful in many ways but it just hardcore censors facts and even edits direct quotes to push a [pseudoleftist](pseudoleft.md) propaganda. **Do not trust Wikipedia, especially on anything even remotely touching politics**, always check facts elsewhere, e.g. in old paper books, on Metapedia, Infogalactic etc. As old Wikipedia is still accessible, you may also browse the older, less censored version, to see how it deranged from a project seeking truth to one abusing its popularity for propaganda.

# Xonotic
|
||||
|
||||
Xonotic is a [free as in freedom](free_software.md) fast multiplayer arena [first-person-shooter](fps_game.md) [game](game.md) similar to e.g. [Quake](quake.md). It runs on [GNU](gnu.md)/[Linux](linux.md), [Winshit](windows.md), [BSD](bsd.md) and other systems. It is one of the best libre games, i.e. games that are completely free by both code and data/content. It is available under [GPLv3](gpl.md). Its gameplay, graphics and customizability are pretty great, it may well be the best in the AFPS genre, even compared to AAA [proprietary](proprietary.md) games -- this kind of quality is very rare among libre/noncommercial games.

UPDATE: **Xonotic as a game died in summer 2023** when the retarded developers couldn't get an erection without CONSOOMING NEW CONTINT and started just blindly pushing bugs and balance breaking changes without listening to player complaints at all, demonstrating [update culture](update_culture.md) at its worst. The main server became a meme overnight, all [fun](fun.md) (such as friendly push) was removed from the game to create a "safe space" for players, possibly to get the game ready for Steam sales or make it more open to noobs and advertisers. RIP. If you can [fork](fork.md) Xonotic and restore it to its previous glory, please do so.

{ LOL the main server now banned me for voicing criticism of these updates xD RIP, I guess that's it for me. It was a nice journey. ~drummyfish }
|
||||
|
||||
{ I've been playing Xonotic for years, it's really an excellent game. I've met a lot of nice people there as the players are usually programmers and people looking for [FOSS](foss.md). The gameplay is addictive and relaxing and you can have a great chat during the game. Of course it's kind of bloated but Xonotic is a masterpiece. ~drummyfish }
