+============================================================
+PyPy
+============================================================
+
+
+PyPy is...
+--------------------------
+
+* Another Python interpreter
+
+* with a JIT compiler
+
+
+PyPy was...
+-------------------
+
+* Around since 2003
+
+* (advertised as) production ready since December 2010
+
+ - release 1.4
+
+* Funding
+
+ - EU FP6 programme
+
+ - Eurostars programme
+
+ - donations
+
+ - ...
+
+
+PyPy 1.9: current status
+------------------------
+
+* Faster
+
+ - **1.7x** than 1.5 (Summer 2011)
+
+ - **2.2x** than 1.4 (December 2010)
+
+ - **5.5x** than CPython
+
+* Implements Python 2.7.3
+
+* Many more "PyPy-friendly" programs than before
+
+* Packaging
+
+ - |scriptsize| Debian, Ubuntu, Fedora, Homebrew, Gentoo, ArchLinux, ... |end_scriptsize|
+
+ - |scriptsize| Windows (32bit only), OS X |end_scriptsize|
+
+* C extension compatibility
+
+ - runs (big part of) **PyOpenSSL** and **lxml**
+
+
+PyPy organization
+-----------------
+
+* Part of SFC -- Software Freedom Conservancy
+
+ - Bradley successfully fighting U.S. bureaucracy
+
+ - we are happy about it
+
+
+* Funding model
+
+ - py3k, numpy, STM
+
+ - more than 100'000$ in donations
+
+ - from individuals, large companies and the PSF
+
+
+PyPy's JIT compiler
+-------------------
+
+* Removes abstraction
+
+* Almost never gives up
+
+* x86-32, x86-64, ARMv7, (POWER64)
+
+* (Works with other languages)
+
+
+Real world applications
+-----------------------
+
+* Positive feedback
+
+* http://speed.pypy.org/
+
+* demo
+
+
+py3k
+------------------------
+
+* ``py3k`` branch in mercurial
+
+ - developed in parallel
+
+ - Python 3 written in Python 2
+
+* Focus on correctness
+
+* Dropped some interpreter optimizations for now
+
+* First 90% done, remaining 90% not done
+
+* Majority of the funds by Google
+
+
+NumPy
+-----
+
+* progress going slowly
+
+* multi dimensional arrays, broadcasting, fancy indexing
+
+* all dtypes, except complex, strings and objects
+
+* good results for performance
+
+
+STM
+---------------------------
+
+* Software Transactional Memory
+
+* "Remove the GIL"
+
+* But also, new models (better than threads)
+
+* demo
+
+
+Calling C
+---------
+
+.. image:: standards.png
+ :scale: 60%
+ :align: center
+
+Calling C landscape
+-------------------
+
+* CPython C extensions
+
+* SWIG, SIP, wrapper generators
+
+* ctypes
+
+* Cython
+
+* CFFI (our new thing)
+
+CFFI
+----------
+
+|scriptsize|
+|example<| Example |>|
+
+ .. sourcecode:: pycon
+
+ >>> from cffi import FFI
+ >>> ffi = FFI()
+ >>> ffi.cdef("""
+ ... int printf(const char *format, ...);
+ ... """)
+ >>> C = ffi.dlopen(None)
+ >>> arg = ffi.new("char[]", "world")
+ >>> C.printf("hi there, %s!\n", arg)
+ hi there, world!
+
+|end_example|
+|end_scriptsize|
+
+CFFI
+----
+
+* Many more examples
+
+* Including macro calls and most subtleties of C
+
+* http://cffi.readthedocs.org
+
+
+Conclusion
+----------
+
+* Try out PyPy on real code
+
+* http://pypy.org/
+
+* Thank you!
