gcc-python-plugin is a plugin for GCC 4.6 onwards which embeds the
CPython interpreter within GCC, allowing you to write new compiler
warnings in Python, generate code visualizations, etc.
It ships with "gcc-with-cpychecker", which implements static analysis
passes for GCC aimed at finding bugs in CPython extensions. In
particular, it can automatically detect
reference-counting errors:

Microsoft has released a compiler package for Python 2.7 to make it easier for people to build and distribute their C extension modules on Windows.
The Microsoft Visual C++ Compiler for Python 2.7 is available from: http://aka.ms/vcpython27
This package contains all the tools and headers required to build C extension modules for Python 2.7 32-bit and 64-bit (note that some extension modules require 3rd party dependencies such as OpenSSL or libxml2 that are not included). Other versions of Python built with Visual C++ 2008 are also supported.
You can install the package without requiring administrative privileges and, with the latest version of setuptools, use tools such as pip, wheel, or a setup.py file to produce binaries on Windows.
(Note: This version of Visual C++ is no longer supported by Microsoft, and so new features, support, or bug fixes are not available.)

When performance matters ...
----------------------------
Simple idioms you can use to make your Python code run faster and
use less memory.
Python applications sometimes need all the performance they can
get. Think of e.g. web, REST or RPC servers. There are several ways
to address this: scale up by using more processes, use Cython, use
PyPy, rewrite parts in C, etc.
However, there are also quite a few things that can be done directly
in Python. This talk goes through a number of examples and show
cases how sticking to a few idioms can easily enhance the
performance of your existing applications without having to revert
to more complex optimization strategies.
The talk was complemented with a lightning talk titled "Pythons and
Flies", which addresses a memory performance idiom and answers one
of the audience questions raised in the above talk.

Python Web Installer
--------------------
Installing Python packages is usually done with one of the available
package installation systems, e.g. pip, easy_install, zc.buildout,
or manually by running "python setup.py install" in a package
distribution directory.
These systems work fine as long as you have Python-only
packages. For packages that contain binaries, such as Python C
extensions or other platform dependent code, the situation is a lot
less bright.
In this talk, we present a new web installer system that we're
currently developing to overcome these limitations.
The system combines the dynamic Python installation interface
supported by all installers ("python setup.py install"), with a web
installer which automatically selects, downloads, verifies and
installs the binary package for your platform.
Talk video and slides:
http://www.egenix.com/library/presentations/PyCon-UK-2014-Python-Web-Instal…
If you are interested in learning more about these idioms and
techniques, eGenix now offers Python project coaching and consulting
services to give your project teams advice on how to achieve best
performance and efficiency with Python:

A pair of basic tkinter desktop utility programs that others
may find useful:
1) frigcal -- a "refrigerator" style calendar desktop GUI
2) mergeall -- do-it-yourself "cloud" storage, script + GUI
Both were coded in part as supplements for book readers, but
have grown useful enough to merit a wider post and broader
user testing. Feedback welcome; details follow.
------------------------------------------------------------------------
1) frigcal -- a "refrigerator" style calendar desktop GUI
Documentation:
http://learning-python.com/README-frigcal.html
Download:
http://learning-python.com/frigcal.zip
Screenshots:
http://learning-python.com/screenshots/01-win7-main-window.pnghttp://learning-python.com/screenshots/02-win7-clones-and-images.pnghttp://learning-python.com/screenshots/
A Python 3.X program that implements a basic personal calendar GUI.
It uses portable iCalendar files for event storage, and sports Python
coded configuration, persistent events, event colorization, multiple
calendar files, multiple month windows, and automatic calendar backups.
This program is not an Outlook replacement: it does not implement tools
such as task scheduling, journaling, alarms, invitations, or recurring
or multiday events. In exchange for its limited utility, though, this
program minimizes code and GUI complexity; reduces the risk of data loss;
and yields a calendar sufficient for most personal needs, that requires
neither a subscription nor an account log-in.
------------------------------------------------------------------------
2) mergeall -- do-it-yourself "cloud" storage, script + GUI
Documentation:
http://www.rmi.net/~lutz/mergeall.html
Download:
http://www.rmi.net/~lutz/mergeall.zip
Screenshots:

A Python 3.X/2.X script and GUI useful for managing backups and changes
in multiple copies of large directory trees (folders). Designed to
quickly synchronize changes in content mirrored across multiple devices
such as laptops, tablets, and USB flashdrives, this program in some
contexts can provide a manual alternative to cloud-based storage.
Directory tree synchronization isn't the same as a "cloud," of course;
but together with fast local storage devices, this program might just
help you avoid paying to store your personal data at sites that may
share it with, or sell it to, both advertisers and government agencies
(who, shockingly, may not have your best interest at heart).

I am pleased to announce the release of mds-utils 2.1.0
<http://www.micheledestefano.joomlafree.it/en/mds-utils.html>.
Features summary
---------------------------
MDS-UTILS provides:
1. a tool for detecting machine endianity.
2. utilities for the Boost uBLAS library. Amongst them, some type traits
for detecting different uBLAS matrix types.
3. some useful classes that allow to treat the old C FILE pointer as a
C++ stream.
4. C++ wrappers of the main Python objects, independent of those in
Boost Python. Wrappers are provided also for NumPy arrays.
5. C++ classes that help on treating Python file objects as C++ streams.
6. a review and refactor of the indexing support in Python extensions.
Now access in write mode is supported too.
7. new C++ *to-Python* and *from-Python* converters for some *Boost
uBlas* objects and for standard Python objects. These converters do not
depend on Boost Python.
8. a new sequence iterator that is able to wrap Python sequences and
allows also to modify them. This feature does not depend on Boost.Python.
9. the NDArrayIterator class, that wraps the Numpy C-API iterator and
allows easy management of conversions to/from Numpy arrays.
10. some SWIG interface files, for easy integration with SWIG extensions
for Python.
Each class is a well-documented, small, easy to use and it should never be
too difficult to learn to use it.
A large percentage of this library makes a heavy usage of the Boost C++
libraries <http://www.boost.org/>: so, they must be installed on the
system. It is assumed that the user is familiar with them.

TextTest is a tool for automatic text-based functional testing. This
means running a batch-mode executable in lots of different ways from
the command line, and using the text output produced as a means of
controlling the behavior of that application. As well as being usable
"standalone", it is an extendable framework for black-box testing
written in Python. It's also useful as a test management tool wrapping
some other test tool as a test runner.

On behalf of the Bokeh team, I am very happy to announce the release of
Bokeh version 0.6.1!
Bokeh is a Python library for visualizing large and realtime datasets on
the web. Its goal is to provide to developers (and domain experts) with
capabilities to easily create novel and powerful visualizations that
extract insight from local or remote (possibly large) data sets, and to
easily publish those visualization to the web for others to explore and
interact with.
This point release includes several bug fixes and improvements over our
most recent 0.6.0 release:
* Toolbar enhancements
* bokeh-server fixes
* Improved documentation
* Button widgets
* Google map support in the Python side
* Code cleanup in the JS side and examples
* New examples
See the CHANGELOG for full details.
In upcoming releases, you should expect to see more new layout capabilities
(colorbar axes, better grid plots and improved annotations), additional
tools, even more widgets and more charts, R language bindings, Blaze
integration and cloud hosting for Bokeh apps.
Don't forget to check out the full documentation, interactive gallery, and
tutorial at
http://bokeh.pydata.org
