Hi,
I am pleased to release PySPH version 1.0a3.
PySPH is an open source (BSD licensed) framework for Smoothed Particle
Hydrodynamics (SPH) simulations. It is implemented in Python and the
performance critical parts are implemented in Cython. A wide variety of
SPH formulations are available and new ones can be easily added.
PySPH allows users to write their high-level code in pure Python. This
Python code is automatically converted to high-performance Cython which
is compiled and executed. PySPH can also be configured to work
seamlessly with OpenMP and MPI.
Documentation: http://pysph.readthedocs.org
Download: http://pypi.python.org/pypi/PySPH/
Development: http://pysph.bitbucket.org
Changelog: http://pythonhosted.org/PySPH/overview.html#changelog
Quick changelog
---------------
- Improve the Application class to make it very easy to do a variety of
things including user-defined command line arguments, adding new tools
and pre/post-step callbacks.
- Add a convenient pysph script to run examples, run tests and view the
results.
- Bundle all examples with the installation so ``pip install PySPH`` is all
you need to run the examples and use the library.
- Use a platform and Python specific directory to store auto-generated
code.
- Silence distracting compiler warnings and only show them when an error
occurs.
For more details see the detailed changelog here:
http://pythonhosted.org/PySPH/overview.html#changelog
Installation
------------
Please see the documentation above for detailed instructions. You
should be able to:
$ pip install pysph
If you need to run the tests you can run ``pip install pysph[test]`` to
automatically fetch the additional dependencies (nose and mock). To use the
viewer you will need mayavi installed. ``pip install pysph[all]`` should fetch
all the dependencies.
Features
--------
- Flexibility to define arbitrary SPH equations in pure Python
- Define your own multi-step integrators in pure Python
- High-performance: our performance is comparable to hand-written
solvers implemented in low-level languages
- Seamless multi-core support with OpenMP
- Seamless MPI support using: http://www.cs.sandia.gov/zoltan/
PySPH supports a variety of SPH formulations including:
- Weakly compressible SPH
- Transport Velocity Formulation
- SPH for elastic dynamics
- Compressible flows

Hello,
fIDDLE is a new Python code editor I have been working on. It started as a rough proof-of-concept for the IDLE Reimagined project based on PyQt, but has diverged somewhat into its own thing.
https://github.com/akehrer/fiddle
Features:
- Interactive interpreter (Python shell)
- Tabbed file editor with code completion
- Easy access to built-in Python documentation (via pydoc)
- Quick search for errors
- Improved traceback information
- One touch code cleaner and code checker
- Easily switch between interpreters (including virtual environments)
There is a Windows executable available in Releases and I have been able to get it working on both Ubunutu and OS X.

________________________________________________________________________
NEWS
The 3.2.9 release of the eGenix mx Base Distribution is the latest
release of our open-source Python extensions. It includes these fixes
and enhancements:
Fixes for all Python Builds
---------------------------
* Fixed the DateTime value range to only cover dates which can be
represented as broken down values. On 32-bit systems, the valid
range now is from -5879608-01-01 to 5879609-12-31, on 64-bit
systems from -25252734927766552-01-01 to
25252734927766553-12-31.Should be enough for most needs :-)
* Fixed the DateTimeDelta value range to only cover deltas which can
be represented as broken down values. On 32-bit systems, the valid
range now is from -2147483647:00:00:00.00 to
2147483647:00:00:00.00, on 64-bit systems from
-104249991374:07:36:32.00 to 104249991374:07:36:32.00.
* Fixed a segfault on Windows when using .strftime() on a DateTime
object with leap seconds. mxDateTime will now raise a ValueError
instead, since the Windows C runtime strftime() doesn't handle leap
seconds and segfaults.
* Fixed a segfault on Windows when using .strftime() with an
unsupported formatting code (e.g. %f). mxDateTime will now raise a
ValueError instead, since the Windows C runtime strftime() doesn't
like unsupported formatting codes or lone % at the end of the
format string and causes a segfault. Thanks to Barry B for
reporting this.
Fixes for Python Debug Builds
-----------------------------
* In this patch level release, we have significantly improved the
compatibility of eGenix mx Base with Python debug builds, which we
previously did not support. Regular Python builds are usually not
affected.
* Fixed crashes of several mx Base packages when using Python debug
builds, which were due to the use of free lists. Free lists are
disabled for Python debug builds now.
* Several mx Base packages crashed during interpreter shutdown when
using Python debug builds.
* mxBeeBase: Fixed a memory allocation error when using Python debug
builds.
* mxDateTime crashed when using Python debug builds due to the use of
free lists and a non-standard way of dealing with errors inside
object constructors, bypassing the logic used by debug builds to
trace object allocation. Thanks to Edson Tadeu M. Manoel for
bringing this to our attention.
* mxTools: Fix a segfault in napply() when using Python debug builds.
Installation Enhancements and Fixes (via included mxSetup)
----------------------------------------------------------
Most of these enhancements and fixes are part of the Python web
installer support we added to mxSetup a while ago. If you want to
learn more about this web installer technology, please see this talk
on the topic:
http://www.egenix.com/library/presentations/PyCon-UK-2014-Python-Web-Instal…
* Fixed traceback when building pure Python packages with mxSetup's
bdist_prebuilt.
* mxSetup's web installer now searches for "purepython" and "anyos"
tags as fallback when looking for OS dependent packages. It also
adds the "anyos" tag to all pure Python packages.
* Refactored the web installer in mxSetup into a class for easier
customization.
* Added --unicode-aware parameter support to bdist_egg when used with
setuptools.
* mxSetup now always produces PEP 440 compatible version numbers
(using mx_version()).
* Prebuilt archives created on Linux2 will now load fine on Linux3
machines. Same for FreeBSD and other systems which retain backwards
compatibility.
* Prebuilt archives will now also be usable on compatible platforms,
e.g. ones compiled on linux2 with linux3 systems and ones for
freebsd8 with freebsd9 or freebsd10.
* Fixed a bug in mxSetup which caused .pyc/.pyo not to get removed
when using 'pip uninstall'.
* Resolved an intermittent error related to hash seeds which
sometimes caused prebuilt archives to not install correctly. Thanks
to Albert-Jan Roskam for reporting this.
* Added Raspberry Pi Ver. 2 support to mxSetup.
* Added support for bdist_wheels to allow building wheels from source
or from prebuilt packages using mxSetup.
* Removed a spurious AttributeError warning showing up when
installing egenix-mx-base prebuilt packages on Windows systems
without C compiler.
eGenix mx Base Distribution 3.2.0 was release on 2012-08-28. Please

After once again multiple (this time only three) years, I am happy to
announce version 0.4.9 of ruamel.orderddict.
Main enhancement since the original release in 2007 is the addition of
the viewkeys/viewitems/viewvalues methods as added to the dictionaries
in Python 2.7
The package can be installed from PyPI, and wheels are available for
Windows.
https://pypi.python.org/pypi/ruamel.ordereddict
Sources are hosted on bitbucket.
---------------------
>From the blurb on ruamel.ordereddict home-page:
This is an implementation of an ordered dictionary with Key Insertion
Order (KIO: updates of values do not affect the position of the key),
Key Value Insertion Order (KVIO, an existing key's position is removed
and put at the back).
Sorted dictionaries are also provided. Currently only with Key Sorted
Order (KSO, no sorting function can be specified, but a transform
function to be applied on the key before comparison can be supplied).
It implementation is directly derived from dictobject.c and its speed is
5-10% slower than dict() and 5-9 times faster than Larosa/Foord
excellent pure Python implemention. With a little helper wrapper
(because of incompatibilities in the more recently implemented
OrderedDict in the standard library), ruamel.ordereddict will also pass
all unittests for OrderedDict.
On behalf of the Python development community and the Python 3.5 release
team, I'm relieved to announce the availability of Python 3.5.0rc2, also
known as Python 3.5.0 Release Candidate 2.
Python 3.5 has now entered "feature freeze". By default new features
may no longer be added to Python 3.5.
This is a preview release, and its use is not recommended for production
settings.
You can find Python 3.5.0rc2 here:
https://www.python.org/downloads/release/python-350rc2/
Windows and Mac users: please read the important platform-specific
"Notes on this release" section near the end of that page.
Happy hacking,

Hello,
ScratchABit is pure-Python, interactive disassembler
(direct-manipulation, textmode UI), suitable for reverse engineering
work of malware analysis, security research, developing open-source
drivers, etc. ScratchABit is architecture-independent and supports
particular CPU using plugins. Plugin API used is compatible with
IDAPython, which is pretty much an industry standard and allow easy
reuse of the wealth of plugins developed by community. A sample plugin
for Intel x86 (32 or 64 bit) is included, based on pure-Python PyMsasid
disassembly engine.
ScratchABit is distributed as a git repository with submodules pulling
in any required components (plugins), allowing quick start even for
people who aren't familiar with Python (Python3 is the only
requirement).
Project is at version 0.9 currently.
