10. Why? would you implement Ruby in Python?

11. Python CPython PyPy

12. Ruby MRI JRuby Rubinius

13. PyPy is a Python implementation

14. PyPy is amazingly fast See http://speed.pypy.org

15. PyPy is written in RPython

16. RPython is a subset of Python

17. RPython can be statically compiled to C

18. RPython is optimised for implementing VMs

19. PyPy is an impl. of Python PyPy is written in

    RPython RPython is compiled to C

20. Topaz is an impl. of Ruby Topaz is written in

    hello hello real 0m3.539s

24. $ cd topaz $ python \ .../pypy/rpython/bin/rpython \ -Ojit targettopaz.py

    RPython → C
25. None

30. Topaz redefines what fast means in the Ruby world

31. Why is it so fast? PyPy!

32. Meta-tracing just-in-time compilation

34. Get the source and try for yourself

35. Is Topaz a Ruby-Python interoperability bridge? No, unfortunately it’s not.

36. Topaz is still very young

37. Contributing is easy
