 Using approximations however doesn't have to imply decrease in precision of the final result -- approximations very well serve [optimization](optimization.md). E.g. approximate metrics help in [heuristic](heuristic.md) algorithms such as [A*](a_star.md). Another use of approximations in optimization is as a quick preliminary check for the expensive precise algorithms: e.g. using bounding spheres helps speed up collision detection (if bounding spheres of two objects don't collide, we know they can't possibly collide and don't have to expensively check this).

+Distrohopping is a serious mental disease that makes people waste lives on constantly switching [GNU](gnu.md)/[linux](linux.md) [distributions](distro.md) ("distros"). This affects mostly those of the lowest skill in tech who feel the need to LARP as wannabe tech nerds; as it's been said, an amateur is obsessed with tools, an expert is obsessed with mastery ([Richard Stallman](rms.md) has for example famously never installed GNU/Linux himself as he has better things to do) -- a true programmer will just settle with a comfy [Unix](unix.md) environment that can run [vim](vim.md) and dedicate his time to creating a timeless source code while the hopper, like a mere animal, is just busy masturbating to a new bastard child of Ubuntu and Arch Linux that adds a new wallpaper and support for [vertical mice](vertical_mouse.md) -- such an activity is basically as retarded as mainstream tech [consumerism](consumerism.md) with the only difference being a hopper isn't limited by finance so he can just distrohop 24/7 and hop himself to death.

doom.md

@@ -8,12 +8,12 @@ Partially thanks to the free release of the engine and its relatively [suckless]
 
 The Doom engine was revolutionary and advanced (not only but especially) video game graphics by a great leap, considering its predecessor [Wolf3D](wolf3D.md) was really primitive in comparison (Doom basically set the direction for future trends in games such as driving the development of more and more powerful [GPUs](gpu.md) in a race for more and more impressive visuals). Doom used a technique called **[BSP rendering](bsp.md)** that was able to render [realtime](realtime.md) 3D views of textured environments with distance fog and enemies and items represented by 2D [billboards](billboard.md) ("sprites"). No [GPU](gpu.md) acceleration was used, graphics was rendered purely with [CPU](cpu.md) (so called [software rendering](sw_rendering.md), GPU rendering would come with Doom's successor [Quake](quake.md)). This had its limitations, for example the camera could not tilt up and down and the levels could not have rooms above other rooms. For this reason some call Doom "[pseudo 3D](pseudo3d.md)" or 2.5D rather than "true 3D". Nevertheless, though with limitations, Doom did present 3D views and internally it did work with 3D coordinates (for example the player or projectiles have 2D position plus height coordinate), despite some dumb YouTube videos saying otherwise. For this reason we prefer to call Doom a **primitive 3D** engine, but 3D nonetheless. However Doom was not just a game with good graphics, it had extremely good gameplay, legendary music and art style and introduced the revolutionary [deathmatch](deathmatch.md) multiplayer, as well as a HUGE modding and mapping community. It was a success in every way -- arguably no other game has since achieved a greater revolution than Doom.
 
-However Doom's success wasn't just due to its graphics, it excelled overall in all areas -- it had brilliant fast and gory gameplay, amazing level design (by John Romero), excellent soundtrack and even a revolutionary [multiplayer](multiplayer.md). The game's backstory was simple and didn't stand in the way of gameplay, it's basically about a tough marine (so called *Doomguy*) on a Mars military base slaying hordes of demos from hell, all in a rock/metal style with a lot of gore and over-the-top violence (chain saws n stuff).

 Doom source code is written in [C89](c.md) and is about 36000 [lines of code](loc.md) long. The original system requirements needed roughly a 30 MHz [CPU](cpu.md) and 4 MB [RAM](ram.md) as a minimum. It had 27 levels (9 of which were shareware), 8 weapons and 10 enemy types.
 
 The game only used [fixed point](fixed_point.md), no [float](float.md)!
 
-Doom also has a [deterministic](determinism.md) [FPS](fps.md)-independent physics which allows for efficient recording of demos of its gameplay and creating [tool assisted speedruns](tas.md), i.e. the time step of game simulation is fixed (35 tics per second). Such demos can be played back in high quality while being minuscule in size and help us in many other ways, for example for verifying validity of [speedruns](speedrun.md). This is very nice and serves as an example of a well written engine (unlike later engines from the same creators, e.g. those of [Quake](quake.md) games which lacked this feature).

 Vector is a basic mathematical object that expresses direction and magnitude (such as velocity, force etc.) and is usually expressed as an "array of numbers". For example in two dimensional space an array `[4,3]` expresses a vector pointing 4 units to the "right" (along X axis) and 3 units "up" (along Y axis) and has the magnitude 5 (which is the vector's length). Vectors are one of the very basic concepts of advanced math and are used almost in any advanced area of math, physics, programming etc. -- basically all of physics and engineering operates with vectors, programmers will mostly encounter them in areas such as 3D [graphics](graphics.md), [physics engines](physics_engine.md) (forces, velocities, acceleration, ...), [machine learning](machine_learning.md) (feature vectors, ...) or [signal processing](signals.md) (e.g. [Fourier transform](fourier_transform.md) just interprets a signal as a vector and transforms it to a different basis) etc. In this article we will implicitly focus on vectors from programmer's point of view (i.e. "arrays of numbers"), which to a mathematician will seem very simplified, but we'll briefly also foreshadow the mathematical view.
 
-Just like in elemental mathematics we deal with "simple" numbers such as 10, -2/3 or [pi](pi.md) -- we retrospectively call such "simple" numbers **[scalars](scalar.md)** -- advanced mathematics generalizes the concept of such a number into vectors ("arrays of numbers", e.g. `[1,0,-3/5]` or `[0.5,0.5]`) and yet further to [matrices](matrix.md) ("two dimensional arrays of numbers") and defines a way to deal with such generalizations into **[linear algebra](linear_algebra.md)**, i.e. we have ways to add and multiply vectors and matrices and solve [equations](equation.md) with them, just like we did in elemental algebra (of course, linear algebra is a bit more complex as it mixes together scalars, vectors and matrices). In yet more advanced mathematics the concepts of vectors and matrices are further generalized to **[tensors](tensor.md)** which may also be seen as "N dimensional arrays of numbers" but further add new rules and interpretation of such "arrays" -- vectors can therefore be also seen as a tensor (of rank 1) -- note that in this context there is e.g. a fundamental distinction between row and column vectors. Keep in mind that vectors, matrices and tensors aren't the only possible generalization of numbers, another one is e.g. that of [complex numbers](complex_number.md), [quaternions](quaternion.md) etc. Anyway, in this article we won't be discussing tensors or any of the more advanced concepts further, they are pretty non-trivial and mostly beyond the scope of mere programmer's needs :) We'll keep it at linear algebra level.

 **Vector is not merely a coordinate**, though the traditional representation of it suggest such representation and programmers often use vector data types to store coordinates out of convenience (e.g. in 3D graphics engines vectors are used to specify coordinates of 3D objects); vector should properly be seen as a **direction and magnitude** which has **no position**, i.e. a way to correctly imagine a vector is something like an **arrow** -- for example if a vector represents velocity of an object, the direction (where the arrow points) says in which direction the object is moving and the magnitude (the arrow length) says how fast it is moving (its [speed](speed.md)), but it doesn't say the position of the object (the arrow itself records no position, it just "hangs in thin air").
