+What is this talk about a JavaScript and a Prolog interpreter in PyPy?
+Since a Python interpreter is a rather large and intricate thing, our toolsuite
+became quite advanced to support it. Therefore people had the idea of using it
+to implement interpreters for other dynamic languages than Python and get a lot
+of things for free (translation to various languages, stackless features,
+garbage collection, implementation of various things like arbitraryly long
+integers). Therefore people started to implement a `JavaScript interpreter`_
+(Leonardo Santagada as his Summer of PyPy project) and a `Prolog interpreter`_
+(Carl Friedrich Bolz as his Masters thesis). Both projects are undocumented and
+unfinished, at the moment (the Prolog interpreter being less unfinished).

 How do I get into PyPy development?  Can I come to sprints?
+Sure you can come to sprints! We always welcome newcomers and try to help them
+get started in the project as much as possible (e.g. by providing tutorials and
+pairing them with experienced PyPy developers). Newcomers should have some
+Python experience and read some of the PyPy documentation before coming to a

+the most immediate mean to get feedback (at least during some parts of the day,
+many PyPy developers are in Europe) and the mailing list is better for long
