+### ruby in ruby
+
+- speed
+- parallelism
+- clarity / understandibility
+
+
+
+### Impossible, no
+
+- Metasm, generate binary in ruby
+- whitequark Parse
+- c interface, not needed
+
+
+
+### Difficult / low level - no
+
+- exception in c is difficult, no c, not difficult
+- function / os calling surprisingly easy
+- vm - just code
+
+
+
+### Architecture
+
+- arm   + elf --> binary
+- parslet parser, ast
+- virtual machine - object machine
+- register machine
+- passes (vm->reg , reg optimisation , extensible)
+
+
+- parfait (pure "normal" ruby) std/core on top
+- builtin, code that can not be coded in ruby (ie array[])
+- macro , shared code for builtin
+
+- object memory layout, cache lines , type info external
+  (type word / layout ref / payload ) 
+

+### Understand the language at a new level, new possibilities
+
+### Ruby makes eaven a vm easy & understandable
+
+### Gems / bundler make parts independent
+
+### Surprisingly fast
+(6 weeks for first executable)
+
+### Surprisingly fun !!
+and wasn't ruby supposed to be
