[ANN] python-blosc v1.2.5
by Valentin Haenel 15 Apr '15

15 Apr '15

============================= Announcing python-blosc 1.2.5 ============================= What is new? ============ This release contains support for Blosc v1.5.4 including changes to how the GIL is kept. This was required because Blosc was refactored in the v1.5.x line to remove global variables and to use context objects instead. As such, it became necessary to keep the GIL while calling Blosc from Python code that uses the multiprocessing module. In addition, is now possible to change the blocksize used by Blosc using ``set_blocksize``. When using this however, bear in mind that the blocksize has been finely tuned to be a good default value and that randomly messing with this value may have unforeseen and unpredictable consequences on the performance of Blosc. Additionally, we can now compile on Posix architectures, thanks again to Andreas Schwab for that one. For more info, you can have a look at the release notes in: https://github.com/Blosc/python-blosc/wiki/Release-notes More docs and examples are available in the documentation site: http://python-blosc.blosc.org What is it? =========== Blosc (http://www.blosc.org) is a high performance compressor optimized for binary data. It has been designed to transmit data to the processor cache faster than the traditional, non-compressed, direct memory fetch approach via a memcpy() OS call. Blosc is the first compressor that is meant not only to reduce the size of large datasets on-disk or in-memory, but also to accelerate object manipulations that are memory-bound (http://www.blosc.org/docs/StarvingCPUs.pdf). See http://www.blosc.org/synthetic-benchmarks.html for some benchmarks on how much speed it can achieve in some datasets. Blosc works well for compressing numerical arrays that contains data with relatively low entropy, like sparse data, time series, grids with regular-spaced values, etc. python-blosc (http://python-blosc.blosc.org/) is the Python wrapper for the Blosc compression library. There is also a handy tool built on Blosc called Bloscpack (https://github.com/Blosc/bloscpack). It features a commmand line interface that allows you to compress large binary datafiles on-disk. It also comes with a Python API that has built-in support for serializing and deserializing Numpy arrays both on-disk and in-memory at speeds that are competitive with regular Pickle/cPickle machinery. Installing ========== python-blosc is in PyPI repository, so installing it is easy: $ pip install -U blosc # yes, you should omit the python- prefix Download sources ================ The sources are managed through github services at: http://github.com/Blosc/python-blosc Documentation ============= There is Sphinx-based documentation site at: http://python-blosc.blosc.org/ Mailing list ============ There is an official mailing list for Blosc at: blosc(a)googlegroups.com http://groups.google.es/group/blosc Licenses ======== Both Blosc and its Python wrapper are distributed using the MIT license. See: https://github.com/Blosc/python-blosc/blob/master/LICENSES for more details. ---- **Enjoy data!**

[ANN] pyOpenSSL 0.15
by Hynek Schlawack 14 Apr '15

14 Apr '15

Greetings fellow Pythoneers, I'm happy to announce that pyOpenSSL 0.15 is now available. pyOpenSSL is a set of Python bindings for OpenSSL. It includes some low-level cryptography APIs but is primarily focused on providing an API for using the TLS protocol from Python. Check out the PyPI page (<https://pypi.python.org/pypi/pyOpenSSL>) for downloads. *** This is the last release under the stewardship of Jean-Paul Calderone and the maintainership is now taken over by the Python Cryptography Authority (PyCA) which has been developing the C-bindings for pyOpenSSL for a while (aka cryptography). We’d like to thank him for his great work over the past years and hope to be able to keep moving the project into a direction that will make him only slightly sad. *** The highlights of this release include: - Support to ECDHE, - NPN and ALPN support, - …many bug fixes! It’s worth pointing out that OpenSSL functions generally work on *byte strings* because they mirror OpenSSL APIs and OpenSSL is not Unicode-aware. Passing Unicode strings tends to accidentally work due do implicit decodes on Python 2 but they emit a DeprecationWarning now. Please note that DeprecationWarnings are silenced by default on Python 2.7. See the ChangeLog at <https://github.com/pyca/pyopenssl/blob/0.15/ChangeLog> for more details! On behalf of PyCA, Hynek Schlawack

Leo 5.1 b2 released
by edreamleo＠gmail.com 11 Apr '15

11 Apr '15

[Leo](http://leoeditor.com/) 5.1 b2 is now available [at SourceForge.](http://sourceforge.net/projects/leo/files/Leo/) Leo is a PIM, an IDE and an outliner. b2 restores the proper operation of @nosent. It is recommended for anyone using Leo 5.1 b1. **The highlights of Leo 5.1** This release features **@clean** trees, one of the most important developments in Leo's history. @clean nodes create external files without sentinel comments, yet Leo can update @clean trees from changes made to the corresponding external files, something long thought impossible. @clean trees preserve clone links and user attributes (uA's). Reading @clean trees is faster than reading @auto or @shadow trees. Steve Zatz [explains why @clean changes everything.](http://leoeditor.com/testimonials.html#steve-zatz-explains-why… The [Mulder/Ream algorithm](http://leoeditor.com/appendices.html#the-mulder-ream-update-algo… updates @clean trees from changes made in the corresponding external files. This is a completely rewritten and much simpler version of Bernhard Mulder's original @shadow update algorithm. **More highlights** * A new [web page](http://leoeditor.com/load-leo.html) displays .leo files in the browser. * Added **command history** to Leo's minibuffer. * A new IdleTime class greatly simplifies idle-time handling. * Leo now honors @language inside @doc parts * @data nodes can be composed of their descendant nodes. * @shadow is now deprecated. @clean is superior to @shadow in all respects. Leo will support all flavors of @auto indefinitely.
