PyPy v5.9 Released, Now Supports Pandas, NumPy
The PyPy team is proud to release both PyPy3.5 v5.9 (a beta-quality interpreter for Python 3.5 syntax) and PyPy2.7 v5.9 (an interpreter supporting Python 2.7 syntax). NumPy and Pandas now work on PyPy2.7 (together with Cython 0.27.1). Many other modules based on C-API extensions work on PyPy as well. Cython 0.27.1 (released very recently) supports more projects with PyPy, both on PyPy2.7 and PyPy3
PyPy v5.8 released
The PyPy team is proud to release both PyPy2.7 v5.8 (an interpreter supporting Python 2.7 syntax), and a beta-quality PyPy3.5 v5.8 (an interpreter for Python 3.5 syntax). The two releases are both based on much the same codebase, thus the dual release. Note that PyPy3.5 supports Linux 64bit only for now. This new PyPy2.7 release includes the upstream stdlib version 2.7.13, and PyPy3.5 includes the
Using CFFI for embedding — CFFI 1.17.0.dev0 documentation
Using CFFI for embedding¶ You can use CFFI to generate C code which exports the API of your choice to any C application that wants to link with this C code. This API, which you define yourself, ends up as the API of a .so/.dll/.dylib library—or you can statically link it within a larger application. Possible use cases: Exposing a library written in Python directly to C/C++ programs. Using Python t

Cython versus CFFI / fuzzy notepad
(This article has been translated into Russian by Everycloudtech—thanks!) I have a hilariously unfinished Python module I work on from time to time named sanpera. It’s an imaging library for Python, with the vain hope that it might replace PIL someday. But this isn’t about sanpera. sanpera happens to be powered by ImageMagick. I distinguish this from being an “ImageMagick wrapperâ€, as it explicitl
PyPy and ijson - a guest blog post
This gem was posted in the ijson issue tracker after some discussion on #pypy, and Dav1dde kindly allowed us to repost it here: "So, I was playing around with parsing huge JSON files (19GiB, testfile is ~520MiB) and wanted to try a sample code with PyPy, turns out, PyPy needed ~1:30-2:00 whereas CPython 2.7 needed ~13 seconds (the pure python implementation on both pythons was equivalent at ~8 min
Installation and Status — CFFI 1.18.0.dev0 documentation
Installation and Status¶ Quick installation for CPython (cffi is distributed with PyPy): pip install cffi or get the source code via the Python Package Index. In more details: This code has been developed on Linux, but should work on any POSIX platform as well as on Windows 32 and 64. (It relies occasionally on libffi, so it depends on libffi being bug-free; this may not be fully the case on some
CFFI 1.0.1 released
CFFI 1.0.1 final has now been released for CPython! CFFI is a (CPython and PyPy) module to interact with C code from Python. The main news from CFFI 0.9 is the new way to build extension modules: the "out-of-line" mode, where you have a separate build script. When this script is executed, it produces the extension module. This comes with associated Setuptools support that fixes the headache of dis
