+PyPy - the fastest Python interpreter
+=============================================
+
+The PyPy project has recently gathered a lot of attention for its
+progress in speeding up the Python language -- it is the fastest,
+most compatible and most stable 'alternative´ Python interpreter.  No
+longer merely a research curiosity, PyPy is now suitable for production
+use. I would like to present PyPy, it's current status, near future goals
+and the general performance Python landscape.
+
+NOTES TO ORGANIZERS:
+
+I've been PyPy core developer since 2006 and presenting PyPy to wider audience
+since 2007. I've been to conferences all over the world, speaking about PyPy
+and other Python topics. This talk will hopefully introduce the conference
+audience to what PyPy is, how to use it in your code and what benefits can
+you expect.

 it's created as a local object that's only visible to the current thread.
