+Samuele Pedroni is one of the main developers and designers of PyPy, a
+meta-circular implementation of Python trying to redefine the
+simplicity/flexibility/performace trade-offs in VM design.
+
+PyPy is both an open source and a funded project under the Framework
+Program 6 of the EU.
+
+Samuele Pedroni has a long-time interest in language design and
+implementation, data-flow and abstract interpretation based program
+analysis and manipulation and dynamic dispatching.
+
+He has been a long time maintainer of Jython (Python implementation
+for the JVM). He has also contributed to aspects of the current design
+of Python. He is a Python Software Foundation member.
+
+Samuele Pedroni received a Computer Science flavoured diploma
+from ETH Zurich.

 Open Virtual Machines
 ==========================
 
-...
+Reconfigurable at run time to run 
+specific languages.
+
+- Open research area.
+
+- Large design space.
+
+- What are the best primitives?
+
+- Likely same trade-offs in
+  more acute form: need sharp tools.
 
 GC Pressure
 ======================
-...
+
+RPython is still a garbage collected language.
+
+Large allocation rate from interpreter objects
+(boxes, frames) but easily temporary objects
+too.
+
+Good allocation removal optimisations
+and memory management very much needed.
