bcolz 0.11.0 released!
by Francesc Alted Sept. 9, 2015

Sept. 9, 2015

======================= Announcing bcolz 0.11.0 ======================= What's new ========== Although this is mostly a maintenance release that fixes some bugs, the setup.py is enterily based now in setuptools and has been greatly modernized to use a new versioning system. Just this deserves a bump in the minor version. Thanks to Gabi Davar (@mindw) for such a nice improvement. Also, many improvements in the Continuous Integration part (and hence not directly visible to users) have been made by Francesc Elies (@FrancescElies). Thanks for his quiet but effective work. And last but not least, I would like to announce that Valentin Haenel (@esc) just stepped down as release manager. Thanks Valentin for all the hard work that you put in making bcolz a better piece of software! 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/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

[RELEASED] Python 3.5.0rc4 is now available!
by Larry Hastings Sept. 9, 2015

Sept. 9, 2015

On behalf of the Python development community and the Python 3.5 release team, I'm surprised to announce the availability of Python 3.5.0rc4, also known as Python 3.5.0 Release Candidate 4. Python 3.5.0 Release Candidate 3 was only released about a day ago. However: during testing, a major regression was discovered, reported on the issue tracker as #25027: http://bugs.python.org/issue25027 Python 3.5 includes some big changes on how Python is built on Windows. One of those changes resulted in Python processes on Windows exceeding the maximum number of loadable shared libraries. As a result Windows builds of Python could no longer run major Python software stacks like Pandas and Jupyter. Fixing this required non-trivial last-minute changes to the Windows build--and those changes need testing. We therefore elected to insert an extra release candidate before the final release, to get these changes into your hands as soon as possible, so that Windows users could test these changes. As with all other Python 3.5 releases to date, this is a preview release, and its use is not recommended for production settings. However, users are encouraged to test with Python 3.5.0rc4, /especially/ Windows users who build or make use of numerous external packages. (Non-Windows users will find little difference between Python 3.5.0rc3 and Python 3.5.0rc4.) You can find Python 3.5.0rc4 here: https://www.python.org/downloads/release/python-350rc4/ Windows and Mac users: please read the important platform-specific "Notes on this release" section near the end of that page. Please kick the tires, //arry/ p.s. Special thanks from the Python 3.5 release team to Christoph Gohlke for the bug report!

[RELEASED] Python 3.5.0rc3 is now available
by Larry Hastings Sept. 8, 2015

Sept. 8, 2015

On behalf of the Python development community and the Python 3.5 release team, I'm relieved to announce the availability of Python 3.5.0rc3, also known as Python 3.5.0 Release Candidate 3. The next release of Python 3.5 will be Python 3.5.0 final. There should be few (or no) changes to Python 3.5 between rc3 and final. This is a preview release, and its use is not recommended for production settings. You can find Python 3.5.0rc3 here: https://www.python.org/downloads/release/python-350rc3/ Windows and Mac users: please read the important platform-specific "Notes on this release" section near the end of that page. Happy hacking, //arry/

PyCA cryptography 1.0.1 released
by Paul Kehrer Sept. 6, 2015

Sept. 6, 2015

PyCA cryptography (https://github.com/pyca/cryptography) 1.0.1 has been released! cryptography is a package which provides cryptographic recipes and primitives to Python developers. Our goal is for it to be your "cryptographic standard library". We support Python 2.6-2.7, Python 3.3+, and PyPy 2.6+. Changelog (https://cryptography.io/en/latest/changelog/) * We now ship OS X wheels that statically link OpenSSL by default. When installing a wheel on OS X 10.10+ (and using a Python compiled against the 10.10 SDK) users will no longer need to compile. * Set the default string mask to UTF-8 in the OpenSSL backend to resolve character encoding issues with older versions of OpenSSL. * Several new OpenSSL bindings have been added to support a future pyOpenSSL release. * Raise an error during install on PyPy < 2.6. 1.0+ requires PyPy 2.6+. Thanks to all the contributors who helped on this release, especially around infrastructure to support the new wheels. -Paul Kehrer (reaperhulk)
