# Drummyfish
|
||||
|
||||
Drummyfish (also tastyfish, drumy etc.) is a programmer, [anarchopacifist](anpac.md) and proponent of [free software/culture](free_software.md), who started [this wiki](lrs_wiki.md) and invented the kind of software it focuses on: [less retarded software](lrs.md) (LRS). Besides others he has written [Anarch](anarch.md), [small3dlib](small3dlib.md), [raycastlib](raycastlib.md) and [SAF](saf.md). He has also been creating free culture art.

He has also been creating free culture art and otherwise contributing to free projects such as [OpenMW](openm.md); he's been contributing with [public domain](pd.md) art of all kind (2D, 3D, music, ...) and writings to [Wikipedia](wikipedia.md), [Wikimedia Commons](wm_commons.md), [opengameart](oga.md), [libregamewiki](lgw.md), freesound and others. Drummyfish is crazy and has no [real life](irl.md), he is pretty retarded when it comes to leading projects or otherwise dealing with people or practical life.

Aside from creating [LRS](lrs.md) drummyfish has contributed to a few [FOSS](foss.md) projects such as [OpenMW](openm.md). He's been contributing with [public domain](pd.md) art of all kind (2D, 3D, music, ...) and writings to [Wikipedia](wikipedia.md), [Wikimedia Commons](wm_commons.md), [opengameart](oga.md), [libregamewiki](lgw.md), freesound and others.

Drummyfish's real name is Miloslav Číž, he was born on 24.08.1990 and lives in Moravia, Czech Republic. He started programming at high school in [Pascal](pascal.md), then he went on to study [compsci](compsci.md) (later focused on [computer graphics](graphics.md)) in a Brno University of Technology and got a master's degree, however he subsequently refused to find a job in the industry, partly because of his views (manifested by [LRS](lrs.md)) and partly because of mental health issues (depressions/anxiety/avoidant personality disorder). He rather chose to do less harmful slavery such as cleaning and physical [spam](spam.md) distribution, and continues [hacking](hacking.md) on his programming (and other) projects in his spare time in order to be able to do it with absolute freedom.

In 2019 drummyfish has written a "manifesto" of his ideas called **Non-Competitive Society** that describes the political ideas of an ideal society. It is in the [public domain](public_domain.md) under [CC0](cc0.md) and available for download online.

{ Why doxx myself? Following the [LRS](lrs.md) philosophy, I believe information should be free. [Censorship](censorship.md) -- even in the name of [privacy](privacy.md) -- goes against information freedom. We should live in a society in which people are moral and don't abuse others by any means, including via availability of their private information. And in order to achieve ideal society we have to actually live it, i.e. slowly start to behave as if it was already in place. Of course, I can't tell you literally everything (such as my passwords etc.), but the more I can tell you, the closer we are to the ideal society. ~drummyfish }

# Wikidata
|
||||
|
||||
Wikidata is a large collaborative project (a sister project of [Wikipedia](wikipedia.md), hosted by Wikimedia Foundation) for creating a huge noncommercial [public domain](public_domain.md) [database](database.md) containing information basically about everything. It records data in a form of so called [knowledge graph](knowledge_graph.md), i.e. it connects items and their properties with statements such as "Earth:location:inner Solar System", creating a mathematical structure called a [graph](graph.md). The whole database is available to anyone for any purpose without any conditions, under [CC0](cc0.md)!
|
||||
|
||||
Wikidata is wildly useful and greatly overlooked in the shadow of Wikipedia even though it offers a way to easily obtain large, absolutely [free](free_culture.md) and public domain data sets about anything. The database can be queried with specialized languages so one can e.g. get coordinates of all terrorist attacks that happened in certain time period, a list of famous male cats, visualize the tree of biological species, list Jews who run restaurants in Asia or any other crazy thing. Wikidata oftentimes contains extra information that's not present in the Wikipedia article about the item and that's not even quickly found by [googling](google.md), and the information is sometimes also backed by sources just like on Wikipedia, so it's nice to always check Wikidata when researching anything.
|
||||
|
||||
Wikidata was opened on 30 October 2012. The first data that were stored were links between different language versions of Wikipedia articles, later Wikipedia started to use Wikidata to store information to display in infoboxes in articles and so Wikidata grew and eventually became a database of its own. As of 2022 there is a little over 100 million items, over 1 billion statements and over 20000 active users.
|
||||
|
||||
## Database Structure
|
||||
|
||||
The database is a [knowledge graph](knowledge_graph.md). It stores the following kinds of records:
|
||||
|
||||
- **entities**: Specific "things", concrete or abstract, that exist and are stored in the database. Each one has a unique [ID](id.md), name (not necessarily unique), description and optional aliases (alternative names).
|
||||
- **items**: Objects of the real world, their ID is a number prepended with the letter *Q*, e.g. *[dog](dog.md)* (Q144), *[Earth](earth.md)* (Q2), *idea* (QQ131841) or *[Holocaust](holocaust.md)* (Q2763).
|
||||
- **properties**: Attributes that items may possess, their ID is a number prepended with the letter *P*, e.g. *instance of* (P31), *mass* (P2067) or *image* (P18). Properties may have constraints (created via statements), for example on values they may take.
|
||||
- **statements**: Information about items and properties which may possibly link items/properties (entities) with other items/properties. One statement is so called triplet, it contains a subject (item/property), verb (property) and object (value, e.g. item/property, number, string, ...). I.e. a statement is a record of form *entity:property:value*, for example *dog(Q144):subclass of(P279):domestic mammal(Q57814795)*. Statements may link one property with multiple values (by having multiple statements about an entity with the same property), for example a man may have multiple nationalities etc. Statements may also optionally include *qualifiers* that further specify details about the statement, for example specifying the source of the data.
|
||||
|
||||
The most important properties are probably **instance of** (P31) and **subclass of** (P279) which put items into [sets](set.md)/classes and establish subsets/subclasses. The *instance of* attribute says that the item is an individual manifestation of a certain class (just like in [OOP](oop.md)), we can usually substitute is with the word "is", for example Blondi (Q155695, [Hitler](hitler.md)'s dog) is an instance of dog (Q144); note that an item can be an instance of multiple classes at the same time. The *subclass of* attribute says that a certain class is a subclass of another, e.g. dog (Q144) is a subclass of pet (Q39201) which is further a subclass of domestic animal (Q622852) etc. Also note that an item can be both an instance and a class.
|
||||
|
||||
## How To
|
||||
|
||||
There are many [libraries](library.md)/[APIs](api.md) for wikidata you can use, unlike shitty corporations that guard their data by force wikidata provides data in friendly ways -- you can even download the whole wikidata database in [JSON](json.md) format (about 100 GB).
|
||||
|
||||
The easiest way to retrieve just the data you are interested in is probably going to the online query interface (https://query.wikidata.org/), entering a query (in [SPARQL](sparql.md) language, similar to [SQL](sql.md)) and then clicking download data -- you can choose several formats, e.g. [JSON](json.md), [CSV](csv.md) etc. That can then be processed further with whatever language or tool, be it [Python](python.md), [LibreOffice](libreoffice.md) Calc etc.
|
||||
|
||||
**BEWARE**: the query you enter may easily take a long time to execute and time out, you need to write it nicely which for more complex queries may be difficult if you're not familiar with SPARQL. However wikidata offers online tips on [optimization](optimization.md) of queries and there are many examples right in the online interface which you can just modify to suit you.
|
||||
|
||||
Here are some example of possible queries. The following one selects video [games](game.md) of the [FPS](fps.md) genre:
|
||||
|
||||
```
|
||||
SELECT ?item ?itemLabel WHERE
|
||||
{
|
||||
?item wdt:P31 wd:Q7889. # item is video game and
|
||||
?item wdt:P136 wd:Q185029. # item is FPS
|
||||
|
||||
# this gets the item label:
|
||||
SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". }
|
||||
}
|
||||
LIMIT 100 # limit to 100 results, make the query faster
|
||||
```
|
||||
|
||||
Another query may be this one: select [black holes](black_hole.md) along with their mass (where known):
|
||||
|
||||
```
|
||||
SELECT ?item ?itemLabel ?mass WHERE
|
||||
{
|
||||
{ ?item wdt:P31 wd:Q589. } # instances of black hole
|
||||
UNION
|
||||
{ ?item wdt:P31 ?class. # instance of black hole subclass (e.g. supermassive blackhole, ...)
|
||||
?class wdt:P279 wd:Q589. }
|
||||
|
||||
OPTIONAL { ?item wdt:P2067 ?mass }
|
||||
|
||||
SERVICE wikibase:label { bd:serviceParam wikibase:language "[AUTO_LANGUAGE],en". }
|
||||
}
|
||||
```
