 # Data Structure
 
-Data structure refers to a any specific way in which [data](data.md) is organized in computer memory. A specific data structure describes such things as order, relationships (interconnection, hierarchy, ...), formats and [types](data_type.md) of parts of the data. [Programming](programming.md) is sometimes seen as consisting mainly of two things: design of [algorithms](algorithm.md) and data structures these algorithm work with.

+Data structure refers to a any specific way in which [data](data.md) is organized in computer memory, which often comes with associated efficient operations on such data. A specific data structure describes such things as order, relationships (interconnection, hierarchy, ...), helper values ([checksum](checksum.md), [indices](index.md), ...), formats and [types](data_type.md) of parts of the data. [Programming](programming.md) is sometimes seen as consisting mainly of two things: design of [algorithms](algorithm.md) and data structures these algorithm work with.
 
 As a programmer dealing with a specific problem you oftentimes have a choice of multiple data structures -- choosing the right one is essential for performance and efficiency of your program. As with everything, each data structure has advantages and also its downsides; some are faster, some take less memory etc. For example for a searchable database of text string we can be choosing between a [binary tree](binary_tree.md) and a [hash table](hash_table.md); hash table offers theoretically much faster search, but binary trees may be more memory efficient and offer many other efficient operations like range search and sorting (which hash tables can do but very inefficiently).
 
+**What's the difference between data structure and (a potentially structured/complex) [data type](data_type.md)?** This can be tricky, in some specific cases the terms may even be interchanged without committing an error, but there is an important difference -- data structure is a PHYSICAL ORGANIZATION of data and though it's often associated with operations and algorithms (e.g. a binary tree comes with a natural search algorithm), the stress is on the layout of data in memory; on the other hand data type can be seen as a more abstract term defined by a SET OF ALLOWED VALUES and OPERATIONS on those values, usually without paying much attention to how those values and operations internally work, although in practice of course we rarely ignore this and often talk about a data type as being connected to specific data structure, which may be where the confusion comes from (also `struct` is a name of a data type in some languages, something potentially confusing as well). For example an ASCII text string is a data type, its set of values are all possible sequences of ASCII symbols and operations it allows are e.g. concatenation, substring search, substring replacement etc. This specific data type can be internally implemented differently, though one of the most natural ways is a "zero terminated string", i.e. [array](array.md) of values that always ends with value zero -- this is A DATA STRUCTURE. Because string, a data type, and zero terminated string (an array of values) are so closely connected, we may sometimes hear a *string* being called both a data type and data structure. However consider another example: a [dictionary](dictionary.md) -- this is a DATA TYPE, very frequently used e.g. in [Python](python.md), which allows storage of pairs of values; again dictionary itself is a data type defining only "how it behaves on the outside", but it can be implemented in several ways, for example with [trees](tree.md), [hash tables](hash_table.md) or [arrays](array.md), i.e. different DATA STRUCTURES. Different Python implementations will all offer the same dictionary data type but may use a different underlying data structure for it.

Furthermore many actually useful things exist, e.g. teethed **cylinders/disks** may be used to record plots of data over time or to store and deliver read/only data (e.g. the program instructions) easily, see music boxes and gramophones; **[punch card](punch_card.md)** have widely been used for storing read-only data too. Sometimes deformed cylinders were used as an analog **2D [look up table](lut.md)** for some mathematical [function](function.md) -- imagine e.g. a device that has input *x* (rotating cylinder along its axis) and *y* (shifting it left/right); the cylinder can then at each surface point record function *f(x,y)* by its width which will in turn displace some stick that will mark the function value on a scale. To transfer movement **strings, chains and belts** may also be used. [Random number generation](rng.md) may be implemented e.g. with [Galton board](galton_board.md). If timing is needed, pendulums can be used just like in clock. Some mechanical computers even use pretty complex parts such as mechanical arms, but these are firstly hard to make and secondly prone to breaking, so try to avoid complexity as much as possible.

Some old mechanical calculators worked by requiring the user to plug a stick into some hole (e.g. number he wanted to add) and then manually trace some path -- this can work on the same principle as e.g. the marble computer, but without needing the marbles complexity and size are drastically reduced.
 
 BONUS THOUGHT: We have gotten so much used to using our current electronic digital computers for everything that sometimes we forget that at simulating actual physical reality they may still fail (or just be very overcomplicated) compared to a mechanical simulation which USES the physical reality itself; for example to make a simulation of a tsunami wave it may be more accurate to build an actual small model of a city and flood it with water than to make a computer simulation. That's why aerodynamic tunnels are still a thing. Ancient NASA flight simulators of space ships did use some electronics, but they did not use computer graphics to render the view from the ship, instead they used a screen projecting view from a tiny camera controlled by the simulator, moving inside a tiny environment, which basically achieved photorealistic graphics. Ideas like these may come in handy when designing mechanical computers as simulating reality is often what we want to do with the computer; for example if we want to model a [sine](sin.md) function, we don't have to go through the pain of implementing binary logic and performing iterative calculation of sine approximation, we may simply use a pendulum whose swinging draws the function simply and precisely.

 Pseudoleft uses cheap, logically faulty arguments to deny the existence of race; for example that there are no clear objective boundaries between races -- of course there are not, but how does that imply nonexistence of race? The same argument could also be given even e.g. for the term *species* (see e.g. ring species in which the boundaries are not clear) so as to invalidate it; yet we see no one doubting the existence of various species of animals. That's like saying that color doesn't exist because given any two distinct colors there exists a gradual transition, or that [music](music.md) and noise are the same thing because objectively no clear line can be drawn between them. If by this argument races don't exist, then movie genres also don't exist.

This is extremely important as we don't depend on any single Unix implementation but we have a great variety of choice between which we can switch without greater issues. This is very important for [freedom](freedom.md) -- it prevents monopolization -- and its one of the important reasons to use unix-like systems.
+In one aspect Unix has reached the highest level a software can strive for: it has transcended its implementation and became a [de facto standard](de_facto_standard.md). This means it has become a set of interface conventions, "paradigms", [cultural](culture.md) and philosophical ideas rather than being a single system, it lives on as a concept that has many implementations. This is extremely important as we don't depend on any single Unix implementation but we have a great variety of choice between which we can switch without greater issues. This is very important for [freedom](freedom.md) -- it prevents monopolization -- and its one of the important reasons to use unix-like systems.
+
+The main highlights of Unix are possibly these:
+
+- **[Unix philosophy](unix_philosophy.md)**: a kind of general mindset of software development, usually summed up as **"do one things well"** (rather than ["do everything but poorly"](windows_philosophy.md)) and "make programs work in collaboration with other programs", advising on using universal text interfaces for communication etc. This often comes with the idea of **[pipes](pipe.md)**, a way of chaining programs (typically using the pipe `|` operator, hence the name) by sending one program's output to other program's input.
+- **[everything is a file](everything_is_a_file.md)**: Unix chose to use the [file](file.md) abstraction to enable universal communication of programs with hardware and among themselves, i.e. on unices most things such as printing, reading keyboard, networking etc. will be likely implemented as reading or writing to/from some special (sometimes just virtual) file. This has the advantage of being able to just use some file reading library or syscall, not having to access physical memory bits in memory, which may be difficult, unsafe etc.
+- Text centrism (great [command line](cli.md) preference), value on [portability](portability.md) (even over performance), sharing of source code, freedom of information and openness, connection to [hacker culture](hacking.md), valuing human time over machine time, ...
+- ...
+
+Unix is greatly connected to software [minimalism](minimalism.md), however most unices are still not minimalist to absolute extreme and many unix forks (e.g. [GNU](gnu.md)/[Linux](linux.md)) just abandon minimalism as a priority. So the question stands: **is Unix [LRS](lrs.md) or is it too [bloated](bloat.md)?** The answer to this will be similar to our stance towards the [C](c.md) language (which itself was developed alongside Unix); from our point of view Unix -- i.e. its concepts and some of their existing implementations -- is relatively good, there is a lot of wisdom to take away (e.g. "do one thing well", modularity, "use text interfaces", ...), however these are intermixed with things which under more strict minimalism we may want to abandon (e.g. "everything is a file" requires we buy into the file [abstraction](abstraction.md) and will often also imply existence of a file system etc., which may be unnecessary), so in some ways we see Unix as a temporary "[least evil](least_evil.md)" tool on our way to truly good, extremely minimalist technology. [DuskOS](duskos.md) is an example of operating system more close to the final idea of LRS. But for now Unix is very cool, some Unix-like systems are definitely a good choice nowadays.
