25 Jul '11

Need to get up-to-speed with Python as quickly and as in-depth as possible? Already coding Python but still have areas of uncertainty you need to fill? Then come join me, Wesley Chun, author of Prentice-Hall's bestseller "Core Python" for a comprehensive intro/intermediate course coming up this May in Northern California, then enjoy a beautiful Fall weekend afterwards in San Francisco, the beautiful city by the bay. Please pass on this note to whomever you think may be interested. I look forward to meeting you and your colleagues! Feel free to pass around the PDF flyer linked down below. Write if you have questions. Since I hate spam, I'll only send out one reminder as the date gets closer. (Comprehensive) Intro+Intermediate Python Tue-Thu, 2011 Oct 18-20, 9am-5pm Hope to meet you soon! -Wesley - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - (COMPREHENSIVE) INTRO+INTERMEDIATE PYTHON Although this course may appear to those new to Python, it is also perfect for those who have tinkered with it and want to "fill in the gaps" and/or want to get more in-depth formal training. It combines the best of both an introduction to the language as well as a "Python Internals" training course. We will immerse you in the world of Python in only a few days, showing you more than just its syntax (which you don't really need a book to learn, right?). Knowing more about how Python works under the covers, including the relationship between data objects and memory management, will make you a much more effective Python programmer coming out of the gate. 3 hands-on labs each day will help hammer the concepts home. Come find out why Google, Yahoo!, Disney, ILM/LucasFilm, VMware, NASA, Ubuntu, YouTube, and Red Hat all use Python. Users supporting or jumping to Plone, Zope, TurboGears, Pylons, Django, Google App Engine, Jython, IronPython, and Mailman will also benefit! PREVIEW 1: you will find (and can download) a video clip of a class session recorded live to get an idea of my lecture style and the interactive classroom environment (as well as sign-up) at: http://cyberwebconsulting.com PREVIEW 2: Partnering with O'Reilly and Pearson, Safari Books Online has asked me to deliver a 1-hour webcast a couple of years ago called "What is Python?". This was an online seminar based on a session that I've delivered at numerous conferences in the past. It will give you an idea of lecture style as well as an overview of the material covered in the course. info:http://www.safaribooksonline.com/events/WhatIsPython.html download (reg req'd): http://www.safaribooksonline.com/Corporate/DownloadAndResources/webcastInfo… - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - WHERE: near the San Francisco Airport (SFO/San Bruno), CA, USA WEB: http://cyberwebconsulting.com FLYER: http://cyberwebconsulting.com/flyerPP1.pdf LOCALS: easy freeway (101/280/380) with lots of parking plus public transit (BART and CalTrain) access via the San Bruno stations, easily accessible from all parts of the Bay Area VISITORS: free shuttle to/from the airport, free high-speed internet, free breakfast and regular evening receptions; fully-equipped suites See website for costs, venue info, and registration.

by Michael Ströder 23 Jul '11

23 Jul '11

Find a new release of python-ldap: http://pypi.python.org/pypi/python-ldap/2.4.3 python-ldap provides an object-oriented API to access LDAP directory servers from Python programs. It mainly wraps the OpenLDAP 2.x libs for that purpose. Additionally it contains modules for other LDAP-related stuff (e.g. processing LDIF, LDAPURLs and LDAPv3 schema). Project's web site: http://www.python-ldap.org/ Ciao, Michael. ---------------------------------------------------------------- Released 2.4.3 2011-07-23 Changes since 2.4.2: Lib/ * Mostly corrected/updated __doc__ strings Doc: * Corrected rst files * Added missing modules, functions, classes, methods, parameters etc. at least as auto-generated doc ---------------------------------------------------------------- Released 2.4.2 2011-07-21 Changes since 2.4.1: Lib/ Logging: * pprint.pformat() is now used when writing method/function arguments to the trace log ldap.schema.subentry: * SubSchema.__init__() now has new key-word argument check_uniqueness which enables checking whether OIDs are unique in the subschema subentry * Code-cleaning: consequent use of method SubSchema.getoid() instead of accessing SubSchema.name2oid directly. * SubSchema.getoid() and SubSchema.getoid() now have key-word argument raise_keyerror=0 and raise KeyError with appropriate description.

[ANN] pylint 0.24 / logilab-astng 0.22
by Sylvain Thénault 20 Jul '11

20 Jul '11

Hi there! I'm pleased to announce new releases of pylint and its underlying library logilab-astng. See http://www.logilab.org/project/pylint/0.24.0 and http://www.logilab.org/project/logilab-astng/0.22.0 for more info. Those releases include mostly fixes and a few enhancements. Python 2.6 relative / absolute imports should now work fine and Python 3 support has been enhanced. There are still two remaining failures in astng test suite when using python 3, but we're unfortunatly missing resources to fix them yet. Many thanks to everyone who contributed to this release by submitting patches or by participating to the latest bugs day. What is pylint ? ---------------- Pylint is a python tool that checks if a module satisfy a coding standard. Pylint can be seen as another pychecker since nearly all tests you can do with pychecker can also be done with Pylint. But Pylint offers some more features, like checking line-code's length, checking if variable names are well-formed according to your coding standard, or checking if declared interfaces are truly implemented, and much more (see http://www.logilab.org/projects/pylint/ for the complete check list). The big advantage with Pylint is that it is highly configurable, customizable, and you can easily write a small plugin to add a personal feature. The usage it quite simple : $ pylint mypackage.mymodule This command will output all the errors and warnings related to the tested code (here : mypackage.mymodule), will dump a little summary at the end, and will give a mark to the tested code. Pylint is free software distributed under the GNU Public Licence.

[ANN] bzr 2.3.4 released
by vila 19 Jul '11

19 Jul '11

1 new stable release: 2.3.4 ;) This is a bugfix release and upgrading is recommended for all users of earlier 2.3 releases. Many thanks to everyone who contributed feedback, suggestions, bug reports and patches ! Bazaar is now available for download from https://launchpad.net/bzr/2.3/2.3.4 as a source tarball. On the same URL you'll also find installers for windows and OSX. Packages for Ubuntu are available from the stable PPA, https://launchpad.net/~bzr/+archive/ppa The SRU process for natty is underway so regular users should also get their update soon. FreeBSD ports have been upgraded too. More details below: bzr 2.3.4 ######### :2.3.4: 2011-07-14 This is a bugfix release. Upgrading is recommended for all users of earlier 2.3 releases. This mainly fixes bug #786980 which blocked the SRU process for Ubuntu Natty. External Compatibility Breaks ***************************** None. Bug Fixes ********* * Accept some differences for ``bound_location`` from the config files that were leading to a 'ReadOnlyError: A write attempt was made in a read only transaction' error. (Vincent Ladeuil, #786980) * Don't fail with traceback if `bzr serve` is running as a service on Windows, and there is no USERNAME, nor BZR_EMAIL or other whoami-related environment variables set. (Alexander Belchenko, Bug #660174) Documentation ************* * Updated the "Using stacked branches" section of the user guide to describe committing to stacked branches and expanded its discussion of pushing a stacked branch. (Andrew Bennetts) Testing ******* * Remove the deprecation decorators for ``failUnlessExists`` and ``failIfExists``. The deprecation "will" occur in 2.4, not before. Providing the wrappers is enough as far as 2.3 is concerned. (Vincent Ladeuil #794960)
