Drummyfish (also known as *tastyfish*, *drummy*, *drumy*, *smellyfish* and *i forcefeed my diarrhea to capitalism*) 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), [smallchesslib](smallchesslib.md), [tinyphysicsengine](tinyphysicsengine.md), [SAF](saf.md) and [comun](comun.md). 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 insane/neuroretarded, suffering from anxiety/[depression](depression.md)/etcetc. (diagnosed [avoidant personality disorder](avpd.md)) and has more than once been called a [schizo](schizo.md), though psychiatrists didn't officially diagnose him with schizophrenia (yet). He also has no [real life](irl.md) and is pretty retarded when it comes to leading projects or otherwise dealing with people or practical life. He is a [wizard](wizard.md).

**Drummyfish is the most physically disgusting bastard on [Earth](earth.md)**, no woman ever loved him, he is so ugly people get suicidal thoughts from seeing any part of him.

**Board representation:** a straightforward representation of the go board is as a simple [array](array.md) of squares; each square can be either empty, white or black, that's 3 values that can be stored with 2 bits, which allow storing 4 values, leaving one extra value to be used for some other purpose (e.g. marking illegal ko squares, estimated dead stones, marking last move etc.). 1 byte allows us to store 4 squares this way so we need only 91 bytes to represent the whole 19x19 board. On computers with enough RAM it may be considered to store 1 square in a single byte, making the board take more space but gaining speed (we don't need extra instructions for squeezing bit from/to a byte). Of course we furthermore have to keep track of extra things such as numbers of captured stones.

On computers with enough RAM it may be considered to store 1 square in a single byte or int, making the board take more space but gaining speed thanks to data alignment (we don't need extra instructions for squeezing bit from/to a single byte).
