[ANN] bzr 2.5.0 released
by Vincent Ladeuil March 8, 2012

March 8, 2012

On behalf of the Bazaar team and community, I'm happy to announce availability of a new release of the bzr adaptive version control system. Bazaar <http://bazaar.canonical.com/> is a Canonical project and part of the GNU project <http://gnu.org/> to produce a free operating system. Thanks to everyone who contributed patches, suggestions, and feedback. Bazaar is now available for download from https://launchpad.net/bzr/2.5/2.5.0 as a source tarball. Installers are available for windows and OSX from the url above too. This release marks the start of a new long-term-stable series. From here, we will only make bugfix releases on the 2.5 series (2.5.1, etc, and support it until April 2017), while 2.6 will become our new development series. This is a bugfix and polish release over the 2.4 series, with a large number of bugs fixed (~170 for the 2.5 series alone). The 2.5 series provides a faster smart protocol implementation for many operations, basic support for colocated branches. We have started translating bzr with the 2.5 series: https://translations.launchpad.net/bzr, more than 20 languages have already been registered but these are the early days, contributions welcome. Only a few bugfixes have been included since 2.5b6 so all known fixed bugs are included here. Users are encouraged to upgrade from the other stable series. See http://doc.bazaar.canonical.com/bzr.dev/en/whats-new/whats-new-in-2.5.html for more details, Vincent

PySide Becomes a Qt Add-on
by Matti Airas March 6, 2012

March 6, 2012

PySide [1] has now finished migration from its previous standalone setup to Qt Project [2] infrastructure. Being a Qt Add-on provides PySide a permanent home and perfect alignment with Qt Frameworks. Furthermore, the project gets improved visibility, as well as a simple, carefully thought out meritocratic project structure. In addition to the wiki that is already hosted by Qt, the PySide mailing list [3] and the bug tracker [4] are also now hosted by Qt. More information on the Qt Project can be found on the project web site [2]. The PySide project now follows Qt Project's governance model [5]. The Maintainer for API Extractor, Generatorrunner, and Shiboken is Marcelo Lira. The Maintainer for the PySide component is Hugo Parente Lima. Paulo Alcantara is an Approver for PySide. All other project roles are informal. Srini Kommoori has kindly volunteered to be the webmaster and wikimaster for the project. To developers using PySide the migration is mostly transparent. PySide is still available under the same licensing terms, and the project facilities are still the mostly unchanged. Instead of having a separate Bugzilla instance, the PySide project now utilizes Qt's Jira bug tracker [4]. Also the mailing list address has changed to pyside(a)qt-project.org [3]. Qt Project uses Gerrit [6] for code reviews. Developers contributing code to PySide should do it using Gerrit from now on. Read-only access to the git source code repositories is still provided via Gitorious [7]. *About PySide* PySide is a Python Qt bindings project initiated by Nokia. PySide provides access to not only the complete Qt framework but also Qt Mobility, as well as to generator tools for rapidly generating Python bindings for any C++ libraries. The PySide project is a Qt Add-on, sharing the same infrastructure and governance model as the open Qt Project itself. PySide is developed in the open, with all facilities you would expect from any modern open source project such as all code in a git repository [7], and an open bug tracker [4] for reporting bugs.

No question about writing extensions and using external C libraries with Cython should remain unanswered after this day. Numerical Calculations with NumPy +++++++++++++++++++++++++++++++++ NumPy is the way to work with multi-dimensional numerical arrays in Python. It is fast and provides a high-level programmer interface. This course day teaches you all the basics. Fast NumPy Processing with Cython +++++++++++++++++++++++++++++++++ Working with NumPy you need to avoid loops over arrays to make your code fast. While NumPy provides indexing and other techniques to help you here, some types of algorithms are easier expressed with loops. Combining NumPy with Cython you can write fast loops. Another topic is parallel programming with OpenMP to take advantage of multi-core CPUs that become so common place these days.

On behalf of the Python development team, I'm happy to announce the first alpha release of Python 3.3.0. This is a preview release, and its use is not recommended in production settings. Python 3.3 includes a range of improvements of the 3.x series, as well as easier porting between 2.x and 3.x. Major new features in the 3.3 release series are: * PEP 380, Syntax for Delegating to a Subgenerator ("yield from") * PEP 393, Flexible String Representation (doing away with the distinction between "wide" and "narrow" Unicode builds) * PEP 409, Suppressing Exception Context * PEP 3151, Reworking the OS and IO exception hierarchy * The new "packaging" module, building upon the "distribute" and "distutils2" projects and deprecating "distutils" * The new "lzma" module with LZMA/XZ support * PEP 3155, Qualified name for classes and functions * PEP 414, explicit Unicode literals to help with porting * The new "faulthandler" module that helps diagnosing crashes * Wrappers for many more POSIX functions in the "os" and "signal" modules, as well as other useful functions such as "sendfile()" For a more extensive list of changes in 3.3.0, see http://docs.python.org/3.3/whatsnew/3.3.html To download Python 3.3.0 visit: http://www.python.org/download/releases/3.3.0/ Please consider trying Python 3.3.0a1 with your code and reporting any bugs you may notice to: http://bugs.python.org/ Enjoy! -- Georg Brandl, Release Manager georg at python.org (on behalf of the entire python-dev team and 3.3's contributors)

A Crypto Juniper $9$ secrets library
by Julio Gómez March 4, 2012

March 4, 2012

Hi, I have developed a Python library which encrypt/decrypt Juniper $9$ secrets. I would like it is part of the common Python libraries and be able to install it through APT, YUM, RPM... depending on the system. The library has 2 public methods: one to encrypt and another one to decrypt. An example of use is: >>> import juniper >>> juniper.encrypt ('test') '$9$ZdGkPF39pOR/C' >>> juniper.decrypt ('$9$ZdGkPF39pOR/C') 'test' Could you tell me the process I have to follow to publish the library? Thanks and best regards! Julio Gómez Ortega.
