by Radomir Dopieralski 12 Jul '09

12 Jul '09

I'm proud to announce release 1.3.2 of Hatta wiki engine. http://hatta.sheep.art.pl/ What is Hatta? -------------- Hatta is a small wiki engine designed to run locally or via WSGI inside a directory in a Mercurial repository. All the pages are normal text or binary (for images and such) files, also editable from outside of the wiki -- the page history is taken from the repository. Who is it for? -------------- It's mostly for small development teams to use for documentation of the project right in the repository. It's mostly a plain, traditional wiki, without fancy features to distract from doing real work. Features -------- * single python script file * no installation necessary, just run it in your repository * can also run on the server as WSGI application * fast indexed search and backlinks * lives inside a repository, so can be cloned, merged, etc. * customizable by creating wiki pages with styles, logo, menu, etc. This version ------------ * can search for parts of words now (thanks to Preben Randhol) * huge speedup of search indexing * compatibility with Werkzeug 0.5 * compatibility with Mercurial 1.3 Enjoy! -- Radomir Dopieralski, http://sheep.art.pl

cx_Freeze 4.1
by Anthony Tuininga 12 Jul '09

12 Jul '09

What is cx_Freeze? cx_Freeze is a set of scripts and modules for freezing Python scripts into executables in much the same way that py2exe and py2app do. It requires Python 2.3 or higher since it makes use of the zip import facility which was introduced in that version. Where do I get it? http://cx-freeze.sourceforge.net What's new? Changes from 4.0.1 to 4.1 1) Added support for Python 3.x. 2) Added support for services on Windows. 3) Added command line option --silent (-s) as requested by Todd Templeton. This option turns off all normal output including the report of the modules that are included. 4) Added command line option --icon as requested by Tom Brown. 5) Ensure that Py_Finalize() is called even when exceptions take place so that any finalization (such as __del__ calls) are made prior to the executable terminating. 6) Ensured that empty directories are created as needed in the target as requested by Clemens Hermann. 7) The encodings package and any other modules required to bootstrap the Python runtime are now automatically included in the frozen executable. 8) Ensured that if a target name is specified, that the module name in the zip file is also changed. Thanks to Clemens Hermann for the initial patch. 9) Enabled support for compiling on 64-bit Windows. 10) If an import error occurs during the load phase, treat that as a bad module as well. Thanks to Tony Meyer for pointing this out. 11) As suggested by Todd Templeton, ensured that the include files list is copied, not simply referenced so that further uses of the list do not inadvertently cause side effects. 12) As suggested by Todd Templeton, zip files are now closed properly in order to avoid potential corruption. 13) As suggested by Todd Templeton, data files are no longer copied when the copy dependent files flag is cleared. 14) Enabled better support of setup.py scripts that call other setup.py scripts such as the ones used by cx_OracleTools and cx_OracleDBATools. 15) On Solaris, ldd outputs tabs instead of spaces so expand them first before looking for the separator. Thanks to Eric Brunel for reporting this and providing the solution. 16) On Windows, exclude the Windows directory and the side-by-side installation directory when determining DLLs to copy since these are generally considered part of the system. 17) On Windows, use %* rather than the separated arguments in the generated batch file in order to avoid problems with the very limited argument processor used by the command processor. 18) For the Win32GUI base executable, add support for specifying the caption to use when displaying error messages. 19) For the Win32GUI base executable, add support for calling the excepthook for top level exceptions if one has been specified. 20) On Windows, ensure that the MSI packages that are built are per-machine by default as otherwise strange things can happen. 21) Fixed bug in the calling of readlink() that would occasionally result in strange behavior or segmentation faults. 22) Duplicate warnings about libraries not found by ldd are now suppressed. 23) Tweaked hooks for a number of modules based on feedback from others or personal experience.

Scientific Computing with Python: July 17th webinar
by Amenity Applewhite 11 Jul '09

11 Jul '09

Greetings! We are pleased to announce our third Scientific Computing with Python webinar! July 17th: Step-by-step Chaco Next week, on Friday, July 17th, we'll be taking a look at Chaco, an component of our open-source Enthought Tool Suite. It seems that this powerful tool impressed participants at last month's webinar, as numerous attendees responded with "Cool!! But how can I do that?" So Peter Wang, Enthought's Director of Technical Architecture, has offered to pick up where he left off last month and give a step-by step introduction to Chaco. This will include a closer examination of the code and more in-depth guidance on how use it for visualizing your data with 2D plotting. This event will take place on Friday, July 17th at 1:00pm CDT (6pm UTC) and will last 60 to 90 minutes, depending on the questions asked. If you would like to participate, please register at https://www1.gotomeeting.com/register/158182457 . Can't get enough scientific computing with Python? This Scientific Computing with Python series focuses on the free and open-source Enthought Tool Suite and and should not be confused with our EPD webinar series. The latter is meant to provide customized support for our EPD Basic or above subscribers, and we initially intended for it to be closed to the public. Many non-subscribers have expressed interest in the series, however, so we have decided to allow non-subscribers to add their name to a waiting list for each EPD webinar. While EPD subscribers will be guaranteed entry and attendance will be capped at 35, we'll draw names from the waiting lists to available seats. These webinars are more intimate, with participatory demonstrations and VOIP question and answer available to attendees, and we think it's a great opportunity for us to support the broader SciPy community. For details, seehttp://www.enthought.com/training/webinars.php . Thanks, and see you Friday! The Enthought Team Forward email This email was sent to staff(a)enthought.com by amenity(a)enthought.com.

Announcing freebase-python 1.0
by Andrew Rodriguez 11 Jul '09

11 Jul '09

freebase-python is a library for accessing the open data repository stored at http://freebase.com. Freebase is huge, user-edited database of over 100 million of facts about over 5 million topics, all under the Creative Commons CC-BY license. The freebase-python library 1.0 is now available! It introduces a new syntax for accessing the freebase api, it updates the available commands to reflect the entire web api, and it introduces some cool schema manipulation utilities. It's backwards compatible with previous versions of the library. The new syntax makes it easy to start running with freebase: >>> import freebase >>> print freebase.mqlread({"id" : "/en/the_beatles", "name" : None}) {u'id': u'/en/the_beatles', u'name': u'The Beatles'} You can also access freebase.sandbox as easily: >>> import freebase.sandbox >>> print freebase.sandbox.mqlread(...) freebase-python can now do all of the current api calls that the website handles. For a full list of the api calls and examples, you can refer to http://code.google.com/p/freebase-python/wiki/GettingStarted . The schema manipulation utilities introduced make it easy copy and move types, properties, and objects. This means that you can save bases to your computer so that their survive a sandbox refresh, keep different versions of your bases and types on your own machine, or move types between bases. There are a few recipes on the freebase- python wiki that you can find here: http://code.google.com/p/freebase-python/w/list?can=2&q=label%3ARecipe%2CSc… freebase-python is also Google App Engine friendly. You can check out how to write your own app at http://code.google.com/p/freebase-python/wiki/GoogleAppEngine . You can also check out a sample app at http://freebase-images.appspot.com . There are also more test and more docs! Installing is easy, if you have easy_install, just say $ easy_install freebase If you don't have easy_install, you can get it by running http://peak.telecommunity.com/dist/ez_setup.py .

by Luke Kenneth Casson Leighton 10 Jul '09

10 Jul '09

http://pyjs.org - Pyjamas is a port of GWT to Python that can run applications both on the Desktop (like python-gtk2) and in all major Web Browsers (as javascript). This is an alpha release - 0.6pre1 - of the Pyjamas Web Widget Set. It is a significant upgrade, incorporating Pyjamas Desktop which can now use Mozilla XULRunner as well as PyWebKitGtk as the browser engine. Significant enhancements have been made to the javascript compiler, which bring python strict features as well as a relaxed (and faster) compile-time option. The reason for the 0.6 pre-release is due to the number of features and improvements added. Many thanks to Kees, Lovely Systems, and all the people from EuroPython 2009 who have helped contribute and generally make Pyjamas fun to work with. Downloads are available from: http://code.google.com/p/pyjamas http://sourceforge.net/projects/pyjamas http://pypi.python.org/pypi/Pyjamas
