Questions Tools for thought
OSS/FOSS/CC Community of contributions
Has Ruby reached its potential?
If yes, Where do we go from here?
If no, What should we be working on?
Celluloid Actor-based concurrent object framework
None
Should Matz be the only one making decisions about Ruby?
If yes, Why?
Concurrency Performance Security Integration API
Refinements Action at a distance
Libraries Frameworks Applications
"active_model".camelize # => "ActiveModel"
Stratification Foundation vs Roof
Composition Joining together
Coordinaton Working together
class A include Enumerable def each # ... end end
a.each { |x| b x }
If no, Who?
RubyConf 12 Toward a Design for Ruby
Have you tried Rubinius?
If yes, How was your experience?
If no, When?

Ruby In Ruby
class Array def [] Ruby.primitive :array_aref raise PrimitiveFailure, "Array#[] primitive
failed" end end
class Array : public Object { private: Fixnum* total_; //
slot Tuple* tuple_; // slot public: attr_accessor(total, Fixnum); attr_accessor(tuple, Tuple); }
class Array : public Object { // Ruby.primitive :array_aref Object*
aref(STATE, Fixnum* idx); }
instruction send_method(literal) [ receiver -- value ] => send flush_ip();
Object* recv = stack_top(); InlineCache* cache = reinterpret_cast<InlineCache*>(literal); Arguments args(cache->name, recv, cNil, 0, 0); Object* ret = cache->execute(state, call_frame, args); (void)stack_pop(); CHECK_AND_PUSH(ret); end

$ make test ... PASS all 951 tests
RubySpec Executable specification of Ruby
23122 examples 158698 expectations
Performance Objects and execution
Memory Generational garbage collection
Method JIT Profile & type-feedback driven
Concurrency Parallelism with no global lock
Tools Understanding execution
Debugger Built-in API and CLI
Profiler Visibility of un-optimized code
Memory Analysis Allocation tracking and histograms
Agent Runtime inspection & control
Innovation Testing the limits
Mirrors Design principles for meta facilities
