Rubinius: A State of the Art Ruby Environment

A quick walk-through about Rubinius as a platform for hosting languages and for Ruby, as well as a quick overview of the upcoming changes and new features.

1. ubinius A state of the Art Ruby Environment
2. @goyox86 Jose Narvaez SOFTWARE ENGINEER
3. Some Background
4. Started by Evan Phoenix on 2006 8 years of development Second alternate implementation that ran Rails Now Maintained by Brian Shirai In a pursuit of a better VM Make Ruby Fast Created the RubySpec Evolved as… MRI drop in replacement
5. The Platform
6. Modern language platform that supports a number of programming languages
7. Bytecode Interpreter
8. Bytecodes
9. fast low-pause precise concurrent generational garbage collector
10. just-in-time (JIT) LLVM based native machine code compiler
11. Builtin FFI Subsystem
15. Many more projects http://rubini.us/projects/
16. Designed for concurrency using native threads to run Ruby(and other) code on all the CPU cores.
17. No global interpeter lock
18. The Ruby Environment
19. Targets Ruby 2.1
20. • Refinements • $SAFE levels Language Exceptions
21. Core, Stdlib and tools built in Ruby
25. Gemified Ruby Standard Library
27. MRI Compatible C-API interface for running C-extensions
28. Tools
29. Builtin Debugger
31. Builtin Profiler
33. Instrumentation
34. StatsD Metrics Subsystem
35. The Future
36. The Future: Platform
37. Fully concurrent GC
38. JIT Improvements • Move it as deeply into Ruby as possible. • It will use runtime type information to combine (or inline) a chain of methods along the call path. • A.KA Smarter.
39. JIT Planner Similar to a query planner in an RDBMS
40. Console Set of tools built on the foundation of the REPL, available at any time, anywhere: In your local box, or you remote production machine.
41. Console::Inspector Tracing the execution of a program and inspecting the program state. local variables, methods currently executing, and more.
42. Console::Measurements Allows to measure how long a particular piece of code takes to run. available at any either your local box, or you production remote server
43. Console::RelativeMeasurements Allows to measure relative measurement of multiple components, usually the chain of methods invoked to perform some computation.
44. Console::Analysis Allows to examine the objects graph, and the execution graph. Examine allocation issues, unwanted retention of references A.K.A memory leaks.
45. CodeDB • It will preserve runtime generated data (otherwise lost). • Enable data it to be used at many points in the lifetime of a program, from the first line written to inspection of a problem in a running production system.
46. The Future: Language
47. Functions
48. Gradual Types for Functions
49. Multiple Dispatch
50. Titanius More useful language platform out of Rubinius
52. If that does not work then it is probably a bug.
53. Questions?
