ANN: bcolz 0.11.3 released!
by Francesc Alted 05 Oct '15

05 Oct '15

======================= Announcing bcolz 0.11.3 ======================= What's new ========== Implemented new feature (#255): bcolz.zeros() can create new ctables too, either empty or filled with zeros. (#256 @FrancescElies @FrancescAlted). Also, in previous, non announced versions (0.11.1 and 0.11.2), new dependencies were added and other fixes are there too. For a more detailed change log, see: https://github.com/Blosc/bcolz/blob/master/RELEASE_NOTES.rst What it is ========== *bcolz* provides columnar and compressed data containers that can live either on-disk or in-memory. Column storage allows for efficiently querying tables with a large number of columns. It also allows for cheap addition and removal of column. In addition, bcolz objects are compressed by default for reducing memory/disk I/O needs. The compression process is carried out internally by Blosc, an extremely fast meta-compressor that is optimized for binary data. Lastly, high-performance iterators (like ``iter()``, ``where()``) for querying the objects are provided. bcolz can use numexpr internally so as to accelerate many vector and query operations (although it can use pure NumPy for doing so too). numexpr optimizes the memory usage and use several cores for doing the computations, so it is blazing fast. Moreover, since the carray/ctable containers can be disk-based, and it is possible to use them for seamlessly performing out-of-memory computations. bcolz has minimal dependencies (NumPy), comes with an exhaustive test suite and fully supports both 32-bit and 64-bit platforms. Also, it is typically tested on both UNIX and Windows operating systems. Together, bcolz and the Blosc compressor, are finally fulfilling the promise of accelerating memory I/O, at least for some real scenarios: http://nbviewer.ipython.org/github/Blosc/movielens-bench/blob/master/queryi… Other users of bcolz are Visualfabriq (http://www.visualfabriq.com/) the Blaze project (http://blaze.pydata.org/), Quantopian (https://www.quantopian.com/) and Scikit-Allel (https://github.com/cggh/scikit-allel) which you can read more about by pointing your browser at the links below. * Visualfabriq: * *bquery*, A query and aggregation framework for Bcolz: * https://github.com/visualfabriq/bquery * Blaze: * Notebooks showing Blaze + Pandas + BColz interaction: * http://nbviewer.ipython.org/url/blaze.pydata.org/notebooks/timings-csv.ipynb * http://nbviewer.ipython.org/url/blaze.pydata.org/notebooks/timings-bcolz.ip… * Quantopian: * Using compressed data containers for faster backtesting at scale: * https://quantopian.github.io/talks/NeedForSpeed/slides.html * Scikit-Allel * Provides an alternative backend to work with compressed arrays * https://scikit-allel.readthedocs.org/en/latest/model/bcolz.html Installing ========== bcolz is in the PyPI repository, so installing it is easy:: $ pip install -U bcolz Resources ========= Visit the main bcolz site repository at: http://github.com/Blosc/bcolz Manual: http://bcolz.blosc.org Home of Blosc compressor: http://blosc.org User's mail list: bcolz(a)googlegroups.com http://groups.google.com/group/bcolz License is the new BSD: https://github.com/Blosc/bcolz/blob/master/LICENSES/BCOLZ.txt Release notes can be found in the Git repository: https://github.com/Blosc/bcolz/blob/master/RELEASE_NOTES.rst ---- **Enjoy data!** -- Francesc Alted

ANN: PyInstaller 3.0
by mzibr.public＠gmail.com 04 Oct '15

04 Oct '15

Hello everybody, on behalf of the PyInstaller development team I'm happy to announce PyInstaller 3.0 after two years of development. http://www.pyinstaller.org === What it is === PyInstaller bundles a Python application and all its dependencies into a single package. The user can run the packaged app without installing a Python interpreter or any modules. PyInstaller reads a Python script written by you. It analyzes your code to discover every other module and library your script needs in order to execute. Then it collects copies of all those files - including the active Python interpreter! - and puts them with your script in a single folder, or optionally in a single executable file. PyInstaller is tested against Windows, Mac OS X, and Linux. However, it is not a cross-compiler: to make a Windows app you run PyInstaller in Windows; to make a Linux app you run it in Linux, etc. PyInstaller has been used successfully with AIX, Solaris, and FreeBSD, but is not tested against them. === Changes === Major changes for this release are: - Python 3 support (3.3 / 3.4 / 3.5). - Remove support for Python 2.6 and lower. - Full unicode support in the bootloader (#824, #1224, #1323, #1340, #1396) - (OSX) Executables built with PyInstaller under OS X can now be digitally signed. - (OSX) 32bit precompiled bootloader no longer distributed, only 64bit. - (Windows) for 32bit bootloader enable flag LARGEADDRESSAWARE that allows to use 4GB of RAM. - New hooks: amazon-product-api, appy, certifi, countrycode, cryptography, gi, httplib2, jsonschema, keyring, lensfunpy, mpl_toolkits.basemap, ncclient, netCDF4, OpenCV, osgeo, patsy, PsychoPy, pycountry, pycparser, PyExcelerate, PyGobject, pymssql, PyNaCl, PySiDe.QtCore, PySide.QtGui, rawpy, requests, scapy, scipy, six, SpeechRecognition, u1db, weasyprint, Xlib. - Add support for automatically including data files from eggs. - Add support for directory eggs support. - Add support for all kind of namespace packages. - Add support for ``pkgutil.extend_path()``. - New option ``--key`` to obfuscate the Python bytecode. The full changelog for this release can be found at: https://pypi.python.org/pypi/PyInstaller/3.0 === License === PyInstaller is licensed under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. Bootloader Exception In addition to the permissions in the GNU General Public License, the authors give you unlimited permission to link or embed compiled bootloader and related files into combinations with other programs, and to distribute those combinations without any restriction coming from the use of those files. (The General Public License restrictions do apply in other respects; for example, they cover modification of the files, and distribution when not linked into a combine executable.) === Feedback === We're eager to listen to your feedback on using PyInstaller: Bug tracker: https://github.com/pyinstaller/pyinstaller/issues Mailing list: http://groups.google.com/group/PyInstaller <p><a href="https://pypi.python.org/pypi/PyInstaller/3.0">PyInstaller 3.0</a> - PyInstaller bundles a Python application and all its dependencies into a single package.

ANN: eGenix PyRun - One file Python Runtime 2.1.1
by eGenix Team: M.-A. Lemburg 01 Oct '15

01 Oct '15

________________________________________________________________________ ANNOUNCING eGenix PyRun - One file Python Runtime Version 2.1.1 An easy-to-use single file relocatable Python run-time - available for Linux, Mac OS X and Unix platforms, with support for Python 2.6, 2.7 and **now also for Python 3.4**. This announcement is also available on our web-site for online reading: http://www.egenix.com/company/news/eGenix-PyRun-2.1.1-GA.html ________________________________________________________________________ INTRODUCTION eGenix PyRun is our open source, one file, no installation version of Python, making the distribution of a Python interpreter to run based scripts and applications to Unix based systems as simple as copying a single file. eGenix PyRun's executable only needs 11MB for Python 2 and 13MB for Python 3, but still supports most Python application and scripts - and it can be compressed to just 3-4MB using upx, if needed. Compared to a regular Python installation of typically 100MB on disk, eGenix PyRun is ideal for applications and scripts that need to be distributed to several target machines, client installations or customers. It makes "installing" Python on a Unix based system as simple as copying a single file. eGenix has been using eGenix PyRun internally in the mxODBC Connect Server product since 2008 with great success and decided to make it available as a stand-alone open-source product. We provide both the source archive to build your own eGenix PyRun, as well as pre-compiled binaries for Linux, FreeBSD and Mac OS X, as 32- and 64-bit versions. The binaries can be downloaded manually, or you can let our automatic install script install-pyrun take care of the installation: ./install-pyrun dir and you're done. Please see the product page for more details: http://www.egenix.com/products/python/PyRun/ ________________________________________________________________________ NEWS This patch level release of eGenix PyRun 2.1 comes with the following enhancements: Enhancements / Changes ---------------------- * Upgraded eGenix PyRun to work with and use Python 2.7.10 per default. * eGenix PyRun will now adjust sys.base_prefix and sys.base_exec_prefix in the same way it does for sys.prefix and sys.exec_prefix. This is needed for Python 3.4 in order to have distutils find the Python.h include file when compiling C extensions. * PyRun for Python 3.4 will now show the correct file name of scripts in tracebacks when running them directly, instead of just '<string>'. * The new internal _sysconfigdata module used by the sysconfig module is now patched with the eGenix PyRun config data as well, to make sure that PyRun doesn't ship with two sets of build config variables. install-pyrun Quick Install Enhancements --------------------------------------------- eGenix PyRun includes a shell script called install-pyrun, which greatly simplifies installation of PyRun. It works much like the virtualenv shell script used for creating new virtual environments (except that there's nothing virtual about PyRun environments). https://downloads.egenix.com/python/install-pyrun With the script, an eGenix PyRun installation is as simple as running: ./install-pyrun targetdir This will automatically detect the platform, download and install the right pyrun version into targetdir. We have updated this script since the last release: * Updated install-pyrun to default to eGenix PyRun 2.1.1 and its feature set. For a complete list of changes, please see the eGenix PyRun Changelog: http://www.egenix.com/products/python/PyRun/changelog.html ________________________________________________________________________ LICENSE eGenix PyRun is distributed under the eGenix.com Public License 1.1.0 which is an Open Source license similar to the Python license. You can use eGenix PyRun in both commercial and non-commercial settings without fee or charge. Please see our license page for more details: http://www.egenix.com/products/python/PyRun/license.html The package comes with full source code. ________________________________________________________________________ DOWNLOADS The download archives and instructions for installing eGenix PyRun can be found at: http://www.egenix.com/products/python/PyRun/ As always, we are providing pre-built binaries for all common platforms: Windows 32/64-bit, Linux 32/64-bit, FreeBSD 32/64-bit, Mac OS X 32/64-bit. Source code archives are available for installation on other platforms, such as Solaris, AIX, HP-UX, etc. _______________________________________________________________________ SUPPORT Commercial support for this product is available from eGenix.com. Please see http://www.egenix.com/services/support/ for details about our support offerings. ________________________________________________________________________ MORE INFORMATION For more information about eGenix PyRun, licensing and download instructions, please visit our web-site: http://www.egenix.com/products/python/PyRun/ About eGenix (http://www.egenix.com/): eGenix is a Python software project, consulting and product company delivering expert services and professional quality products for companies, Python users and developers.

ANN: pysnmp 4.3.0 released
by Ilya Etingof 01 Oct '15

01 Oct '15

Dear all, It is my pleasure to announce the next major version of the pysnmp package (4.3.0) on pypi. This release brings many significant features: * Pure-Python, automatic, on the fly MIB parsing. * Rewritten synchronous high-level interface: walking SNMP agent becomes a matter of exhausting Python generator! * Rewritten Twisted interface: now it is also high-level. * Shiny new high-level asyncio/trollius interfaces. Quite a lot of long-pending fixes ultimately went live. Despite many changes, backward compatibility with previous releases is largely preserved. Finally, proper Sphinx-based documentation (http://pysnmp.sf.net <http://pysnmp.sf.net/>) now accompanies important pieces of the code. Feedback, bug reports and suggestions are welcome! -ilya
