+* 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://www2.svjatoslav.eu/gitbrowse/fifth/doc/index.html][Fifth]]
+    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.
