+Makes lots of complex data intuitive to:

-- Feeds lots of complex data into your brain in intuitive to explore,
- understand and manipulate form by extensively relying on realtime 3D
- graphics and fast feedback loop. (including virtual reality support)

-I love thease existing solutions and properties:
-
-+ Lisp (programming language):
- + Almost no syntax.
- + Code and data intercangeable.
- + Easily self modifying.
-
-+ Smalltalk (programming language / runtime):
- + Everything is object.
- + On the fly modifiable / reprogrammable.
- + Anything can be suspended/resumed from persistent storage on the
- fly.
-
-+ Relational databases:
- + Transactional
- + Indexable / Quickly searchable
-
-+ Git (version control system)
- + Versionable
- + Branchable / mergeable.
- + Transparent cansistency, checksumming and deduplication.
- + (Cool idea:
- https://www.kenneth-truyers.net/2016/10/13/git-nosql-database/)
-
-+ Hadoop (computation system):
- + Many individual connected computers behave as one big
- computer. System is horizontally linearly scalable.
- + Programming abstraction and execution model that naturally divides
- problems te be solved in parallel and result easily combined.
- + Data is spread across nodes, automatic failover, built in
- resiliency.
- + Small pieces of code are automatically transferred to the node
- that contains relatively big data that needs processing (network
- efficiency).
-
-
-I hate to choose between good things. Figuring out a way to combine
-above properties in one system would be beyond awesome.
-
-(I have not solved it yet..)
* Current status
+ Formulated high-level [[id:1f4e1c17-d25f-4d92-aa9b-5785f1d86f4f][vision / goal]].
+ In the process of implementing some of building blocks:
- - [[http://www2.svjatoslav.eu/gitbrowse/sixth-data/doc/index.html][First layer of storage: Simple persistent key-value map.]]
+ - [[http://www3.svjatoslav.eu/projects/sixth-data/][Data storage engine.]]
- - [[http://www2.svjatoslav.eu/gitbrowse/sixth-3d/doc/index.html][In software, pure Java realtime 3D rendering engine.]]
- - [[http://www2.svjatoslav.eu/gitbrowse/sixth-3d-demos/doc/index.html][3D engine demos]]

+ - [[http://www3.svjatoslav.eu/projects/sixth-3d-demos/][3D engine demos]]
+ System is nowhere near complete (given magnitude of effort required
and my free time available). Contributions welcome ! :)
+
+* Computation ideas
++ Program - stored instructions for execution by computer.
+
++ Process - Currently running program.
+ + Process is self contained. Has a full copy of program code and
+ every dependent library.
+
+ + Memory used by processes is content addressed/deduplicated at
+ low level in the system.
+
+ + This allows:
+ + Upgrading software installed in the system without breaking
+ already running processes.
+
+ + Easier migration of running processes between physical
+ computers.
+
+ + Possibility to suspend/resume arbitrary processes to permament
+ storage.
+
+ + Possibility checkpoint/revert running process.
+
+ + Possibility to clone/branch running process.
+
+* Frequently Given Answers
+- Why such name ?
+ - In short: it's just a number.
+ - Many years ago inspired by the ideas of [[https://en.wikipedia.org/wiki/Forth_(programming_language)][Forth (programming
+ language)]] I decided to create my own implementation [[http://www3.svjatoslav.eu/projects/fifth/][Fifth]]
+ (computing/programming environment).
+ - Then I realized I miss type safe object oriented capabilities. So
+ I updated the name to Sixth and switched to Java.
