What is PyPy?
--------------
-* RPython toolchain
+- "PyPy is a fast, compliant alternative implementation of the Python language
(2.7.8 and 3.2.5)."
- - subset of Python
+- Python interpreter
- - ideal for writing VMs
+ * written in RPython
- - JIT & GC for free
+ * **FAST**

+What is RPython?
+----------------
- - **FAST**
+- Subset of Python
-* Whatever (dynamic) language you want
+ * easy to read
- - smalltalk, prolog, PHP, javascript, ...
+ * easy to test
+- JIT & GC for free
-PyPy: past two years (1)
------------------------------
+- General framework for dynamic languages
-- PyPy 2.0 (May 2013)
- * beta ARM, CFFI, unicode performance
-
- * stackless + JIT (eventlet, gevent, ...)
-
-|pause|
-
-- PyPy 2.1 (July 2013)
-
- * stable ARM
-
- * py3k (3.2.3), numpy, general improvements, bugfixes
-
-|pause|
-
-- PyPy 2.2 (November 2013)
-
- * incremental GC, faster JSON
-
- * more JIT, more py3k
-
- * more numpy, numpy C API
-

-PyPy: past two years (2)
+RPython-powered languages
-------------------------
-- PyPy 2.3 (May 2014)
+- **PyPy**
-- Lot of internal refactoring
+- HippyVM: implementing PHP
-- C API for embedding
+ * ~7x faster than standard PHP
- * pypy + uWSGI (thanks to Roberto De Ioris)

-- the usual, boring, general improvements

+RPython translation stages
+--------------------------
-- py3k: 50'852 $ of 105'000 $ (48.4%)
+- (R)Python code
-- numpy: 48'121 $ of 60'000 $ (80.2%)
+|pause|
-- STM, 1st call: 25'000 $
+- ``import``
-- STM, 2nd call: 2'097 $ of 80'000 $ (2.6%)
+ * Python objects (functions, classes, ...)
- * more on STM later
+|pause|
-- thank to all donors!
+- Bytecode analysis, type inference
+
+ * Typed control flow graph
+
+|pause|
+
+- Translator transformations
+
+ * Add GC & JIT
+
+|pause|
+
+- Code generation
+
+ * C code
+
+|pause|
+
+- ``gcc``
+
+ * Compiled executable
+
+
+How does the JIT work?
+----------------------
+
+|pause|
+
+- "Jitcode": very low-level byte code
+
+ * Translates to machine code
+
+- Translation time
+
+ * Add jitcode representation to RPython functions
+
+- Run-time:
+
+ * Detect **hot** loop
+
+ * Trace one code path through the loop
+
+ * Compile (magic!)
+
+ * Profit!
