    %p
      RubyX
      %b compiles
      Ruby code to binary.
      %br
      In
      %b 100%
      pure Ruby.
    %p
      The goal here is to prove that dynamic languages do not have to be slow.
      %br
      Only interpretation is slow, but when
      Ruby is
      =succeed "," do
        %b compiled to binary
      it can be really fast.
    %p
      How fast (X times), will eventually depend on the community.
      The RubyX approach works, but to create an MRI compatible Ruby will
      take many more man-years than I have.
    %p
      RubyX is here to
      =succeed "," do
        =link_to "empower you" , "/project/motivation.html"
      to make your Ruby shine as much as you like.
    %p
      Since RubyX is written in Ruby, anyone can easily join, and
      the project is very open to newcomers. In time the idea is to implement
      a democratic version of open source, as an alternative the current
      "benevolent dictator" model.
    %p
      Contrary to what many newcomers think, ruby-x is also technically easy to join.
      In the end it is just Ruby, and only a very small percent of code is low level.
      We have a list
      =ext_link "of issues" , "https://github.com/ruby-x/rubyx/issues?q=is%3Aissue+is%3Aopen+label%3A%22good+newbie%22"

    %h2.center Status
    %p
      The RubyX compiler is working (ie creates binaries), and the
      =link_to "architecture", "/rubyx/layers.html"
      has been refined over several years.
    %p
      A substantial part of the Ruby language has been implemented:
    %ul
      %li
        Object oriented
        =succeed "." do
          =link_to "calling semantics" , "/rubyx/calling.html"
      %li
        Basic
        =link_to "block creation" , "/blog/implicit-blocks-are-working"
        and passing.
      %li
        Dynamic
        = succeed "." do
          =link_to "method resolution" ,"/rubyx/method_resolution.html"
      %li
        Control Structures, variables and assignment, integer operators.
      %li
        Object based
        =succeed "." do
          =link_to "memory" ,"/rubyx/memory.html"
      %li
        A minimal Runtime of
        = succeed "," do
          =link_to "classes, types" , "/rubyx/parfait.html"
        methods and basic types.
      %li
        =ext_link "Risc machine abstraction" , "/rubyx/layers.html#risc"
        (with SSA and register allocation)
      %li
        A minimal ARM and ELF implementation to create
        = succeed "." do
          %b working binaries
    %h2.center Upcoming work
    %p
      But there is still a lot of work, here are some of the next few topics
      %ul
        %li Inlining and static memory analysis
        %li Start stdlib with String and files
        %li Dynamic Memory management
      There are also many small things anybody can

      The short introduction is under the

      menu.
    %p
      The presentation for
      = ext_link "GrillRb" , "/slides/grillrb"
      is more detailed than the previous unconf Hamburg one.
      But a 20 minute video was made in Hamburg and can be found

      To get to know the system, there is also an interpreter and a basic

    %p
      The
      =link_to "about", "/project/motivation.html"
      section has some info of when and how this started. If you feel like contributing
