QOTW: "So why am I supposed to care about SOAP again? Oh yes, the wizards I can use to generate 'web service end-points' from programming language code.

Iowa Python Users Group - First Meeting
by Mike Driscoll 09 Sep '08

09 Sep '08

Hi, The first meeting date for the Iowa Python Users Group (USA) has been decided. Here are the details: ------------------------------------------------------------ Time / Date: Wednesday, Sept. 24 from 7-9 p.m. Location: Marshall County Sheriff's Office, 3rd floor 2369 Jessup Ave Marshalltown, IA 50158 Unofficial website: http://www.ipug.pythonlibrary.org ------------------------------------------------------------ Don't know how to get there? Check out maps.yahoo.com or maps.google.com. The Sheriff's Office is not actually in Marshalltown. If you take Highway 30 East, towards Marshalltown you'll see it on your left. There's a large water tower there and the building is a rusty red color. There are some signs for a Tractor convention there as well. If you're coming from the other direction, then skip ALL the exits and keep driving until the lanes go from 4 lanes to 2. It should be the second right after that. I am still developing the agenda for our first meeting, but here are some of the things we're going to discuss: - What day really works best for meeting? (if you can't make the first one, you can email me your votes!) - Figure out what domain name our group should have - Decide on what Python web framework to use to create said site (which will be a group project) - Try to come up with what format we want our meetings to take. Plone and Zope users are welcome. In fact, anyone who is interested in Python (regardless of their experience with it) is welcome to come. Let your Iowan Python friends know. Questions or ideas? Send them to me. Thanks! ------------------- Mike Driscoll email: mike at pythonlibrary dot org Blog: http://blog.pythonlibrary.org Python Extension Building Network: http://www.pythonlibrary.org

Jython 2.5 Alpha 2 Released!
by Frank Wierzbicki 06 Sep '08

06 Sep '08

On behalf of the Jython development team, I'm pleased to announce that Jython 2.5a2+ is available for download http://voxel.dl.sourceforge.net/sourceforge/jython/jython_installer-2.5a2.j…. See the installation instructions http://jython.org/Project/installation.html. Django runs pretty well on this release. I am attending Djangocon where Jim Baker and Leo Soto will be presenting on Django on Jython, and I wanted them to be able to tell people to grab a release instead of telling them to grab Jython from svn. There are many bug fixes, but also many bugs that have not yet been fixed. This is an alpha release so be careful!

[ANN] ftputil 2.3 released
by Stefan Schwarzer 06 Sep '08

06 Sep '08

ftputil 2.3 is now available from http://ftputil.sschwarzer.net/download . Changes since version 2.2.4 --------------------------- ftputil has got support for the ``with`` statement which was introduced by Python 2.5. You can now construct host and remote file objects in ``with`` statements and have them closed automatically (contributed by Roger Demetrescu). See the documentation for examples. What is ftputil? ---------------- ftputil is a high-level FTP client library for the Python programming language. ftputil implements a virtual file system for accessing FTP servers, that is, it can generate file-like objects for remote files. The library supports many functions similar to those in the os, os.path and shutil modules. ftputil has convenience functions for conditional uploads and downloads, and handles FTP clients and servers in different timezones. Read the documentation at http://ftputil.sschwarzer.net/documentation . License ------- ftputil is Open Source software, released under the revised BSD license (see http://www.opensource.org/licenses/bsd-license.php ). Stefan
