38 Provide hackable, versioned, optimized, distributed, geometrical,
39 arbitrary dimensional ([[id:96116550-a6a1-4700-bef7-865d0deee7ea][hypercube based]]) data storage and computation
40 engine ([[id:d2375acc-af14-4f18-8ad0-7949501178c5][as inspired by the brain]]) for general purpose visual computing
41 environment called [[http://www2.svjatoslav.eu/gitbrowse/sixth/doc/index.html][Sixth]].
43 Because [[http://www.paulgraham.com/rootsoflisp.html][Lisp is hackable self defined programmable programming
44 language]] it would be used to provide [[https://en.wikipedia.org/wiki/Imperative_programming][imperative programming]] support.

54 + Brain appears to be natural geometrical/parallel data storage and

58 + Even more awesome is that brain appears to operate and is wired as
59 arbitrary/variable dimensional structure:

62 + On top of this, this multidimensional space that brain represents
63 has dynamic/variable resolution/density:
64 + https://www.quantamagazine.org/goals-and-rewards-redraw-the-brains-map-of-the-world-20190328
66 + Such properties allow parallel [[id:171fe375-c737-41e6-b429-a414f6abc5d8][Geometrical computation]] and
67 beautifully fits [[id:01aa65c1-3d44-44a8-9b90-58454bc6be80][CM-1 Connection Machine]] architecture (for extra
68 hardware accelerated solution).
70 ** CM-1 Connection Machine
72 :ID: 01aa65c1-3d44-44a8-9b90-58454bc6be80
74 https://en.wikipedia.org/wiki/Connection_Machine
76 Massively parallel (thousands of CPUs) connected via
77 machine's internal 12-dimensional hypercube network allows to
78 efficiently simulate arbitrary dimensional hypercube and network
79 topology between computational units. So that when we are
80 solving/simulating for example 5 dimensional problem, we can arrange
81 computational units into virtual 5D network. See:
82 http://www.mission-base.com/tamiko/theory/cm_txts/di-ch2.html
84 we can pre-distribute data across computation units and perform
85 parallel [[id:171fe375-c737-41e6-b429-a414f6abc5d8][geometrical computation]].
87 * Reasons for hypercube as a so called first class citizen
89 :ID: 96116550-a6a1-4700-bef7-865d0deee7ea
91 + Hypercube is quite general purpose data structure that naturally
92 encapsulates wide variety data and problems.
94 + Nicely captures apparent [[id:d2375acc-af14-4f18-8ad0-7949501178c5][properties of the brain]].
96 + Naturally supports distributed and parallel [[id:171fe375-c737-41e6-b429-a414f6abc5d8][geometrical data storage
99 + Dedicated hardware like [[id:01aa65c1-3d44-44a8-9b90-58454bc6be80][CM-1]] can be built around hypercube concept
100 that results in data, computation process and hardware, all
101 beautifully fitting together while complementing each other
104 + Hypercube stored data (and computation process) has geometry by its
105 nature and should fit nicely with "3D first" user interface ideology
106 of the parent [[http://www2.svjatoslav.eu/gitbrowse/sixth/doc/index.html][Sixth]] project.
107 * Geometrical computation idea
109 :ID: 171fe375-c737-41e6-b429-a414f6abc5d8
111 ** Distributed computation and data storage
113 :ID: 5d287158-53ea-44a2-a754-dd862366066a
115 Lots of problems can be translated to geometry (use any shapes and as
116 many dimensions as you need). Solution(s) to such problems could be
117 then found via geometrical search/comparison/lookup results. As a
118 bonus, such geometrical *data storage* AND *computation* can be
119 naturally made in *parallel* and *distributed*.
121 Learning means building/updating/re-balancing the model (the hard
122 part). Question answering is making (relatively simple) lookups
123 (geometrical queries) against the model.
124 ** Mapping hypercube to object-oriented model and relational database
126 :ID: a117c11e-97c1-4822-88b2-9fc10f96caec
128 Object oriented programming is inspired by the way human mind
129 operates. It allows programmer to express ideas to computer in a more
132 It is actually also possible to map object model and relational
133 database to geometrical hyperspace:
135 + Object or database table row is a point in hypercube arbitrary
136 dimensional space. Each object member variable or database table
137 column can be mapped to its own dimension in hypercube. That is: if
138 class declares 4 variables for an object, then corresponding object
139 can be stored as a single point inside 4 dimensional
140 hypercube. Variable values translate to point coordinates in that
141 hypercube. That is: numbers and string can be translated to linear
142 value that can be used as a coordinate along particular dimension.
144 + Each object class or database table declares its own hypercube that
145 contain instances (objects) of that class or rows of a table.
147 ** Mapping entity relations in hypercube
149 :ID: b6b15bd2-c78b-4c51-a343-72843a515c29
151 Consider we want to create database of:
154 + Effort: Amount of time contributed by every author to every book
157 Information above can be represented as 3D cube where dimensions are:
162 Points in that cube would nicely capture many to many relations
163 between authors and the books.
165 - More or less defined [[id:f6764282-a6f6-44e6-8716-b428074dd093][Vision / goal]].

169 - Implemented very simple persistent key-value map.
170 - Long term goal is to use it as a backing storage engine and
171 implement more advanced features on top of this via layered
