+Fast enough VMs in fast enough time
+===================================
+
+Who am I?
+---------
+
+* PyPy developer since 2006
+
+XXX
+
+What is PyPy?
+-------------
+
+* an open source project
+
+* a Python interpreter
+
+* **a framework for writing dynamic language VMs**
+
+* an agile project sponsored by EU and others
+
+What is a VM?
+-------------
+
+* a program
+
+* input: a program
+
+* output: the result of executing that program
+
+What does a VM look like?
+-------------------------
+
+* Lexical/analysis parsing (what are the symbols in the program)
+
+* AST construction (what is the structure of the program)
+
+* Bytecode compilation (optional)
+
+* Execution
+
+Where does PyPy come in?
+------------------------
+
+* Tools for writing these program quickly, and efficiently.
+
+  * Helpers for things like parsing
+
+  * Free JIT, and garbage collector
+
+* Mostly you write a totally normal VM in python, and it becomes magically fast
+
+PyPy architecture
+-----------------
+
+* snakes all the way down
+
+* everything is written in Python - including JIT, GC, etc.
+
+* to be precise, a **subset** of Python, called RPython
+
+* your VM has to be implemented in RPython
+
+RPython - the good
+------------------
+
+* The good - it's mostly Python
+
+* Just write python and fix it later
+
+RPython - the bad
+-----------------
+
+* It's restricted
+
+* Most dynamic features don't work, but you can employ all kinds of tricks during import
+
+RPython - the ugly
+-------------------
+
+* Documentation
+
+* Error messages
+
+* Global type inference
