+
+ \maketitle
+
+introduction
+------------
+
+* me - Maciej Fijałkowski, PyPy core developer
+
+* technology - PyPy
+
+* project - PHP interpreter
+
+Wait, what???!!!1
+-----------------
+
+* PHP - by far the most popular language on the web
+
+* PyPy - proven technology for speeding up Python
+
+* examples who can gain: wikipedia, facebook, wordpress....
+
+Current landscape
+-----------------
+
+* Zend - a simple, bytecode-based interpreter
+
+* HipHop - PHP to C++ compiler, facebook project
+
+* HHVM - successor to HipHop, JIT-based, also facebook
+
+Current benchmarks landscape
+----------------------------
+
+* benchmarks are hard
+
+* a set I've seen is mostly numeric or language shootout
+
+* not very representative
+
+* HipHop is 2-4x faster than Zend, HHVM 40% faster than hiphop
+
+* no real-world PHP benchmark suite (a la speed.pypy.org)
+
+PyPy
+----
+
+* fast interpreter for a python language
+
+* but also, a toolchain for constructing interpreters
+
+* comes with a just-in-time compiler
+
+More about PyPy
+---------------
+
+* implementation language of PyPy is RPython
+
+* RPython is a subset of Python
+
+* RPython can be compiled statically to C
+
+|pause|
+
+* ... but also can have just in time compiler generated for
+
+More about RPython
+------------------
+
+* a great language for writing interpreters
+
+|pause|
+
+* a horrible language with tons of tricks
+
+* great results in good enough time
+
+* http://tratt.net/laurie/blog/entries/fast_enough_vms_in_fast_enough_time
+
+Introducing hippy
+-----------------
+
+* PHP interpreter written in RPython
+
+* bug-to-bug compatible with Zend
+
+* interpreter + just in time compiler (for free)
+
+* preliminary study sponsored by facebook
+
+* good preliminary performance results
+
+PHP is hard
+-----------
+
+* crazy standard library
+
+|pause|
+
+* function calls by name
+
+* ``*args`` equivalent, ``apply`` equivalent, etc.
+
+* crazy reference semantics
+
+* copy-on-write and refcounting
+
+\.\.\. but getting it fast is easier
+------------------------------------
+
+* we **do** have a JIT as soon as we write an interpreter
+
+* PyPy has really good technology
+
+Basic construction
+------------------
+
+* interpreter loop
+
+* standard library
+
+|pause|
+
+* typical stuff
+
+Web server integration
+----------------------
+
+* PHP is very request based with throwing out all the data in between
+
+* we want to persist as much as possible
+
+* various optimizations possible
+
+We're hiring
+------------
+
+* want to work on something obscure and challenging?
+
+* with smart people?
+
+* talk to me or Armin
+
+Q&A
+---
+
+* any questions?
