Release of SimPy 1.7 (final)
by Klaus Muller 16 Mar '06

16 Mar '06

It is our pleasure to announce the release of SimPy 1.7 (final). It can be downloaded via the SimPy homepage, http://simpy.sourceforge.net. We thank the SimPy user community for their participation in the testing of SimPy 1.7 beta. What is new? =========== New constructs for inter-process communication, cooperation and resource buffering have been added. SimPy now supports much easier, cleaner implementation of models for producer/consumer and multi-process cooperation scenarios. It does this by the new abstract Buffer class, with sub-classes Level and Store. Processes can asynchronously put items into a buffer by *yield put* and get items with *yield get* statements (both new). Examples of their use are provided in the SimPyModels folder. What is SimPy? ============== SimPy (= Simulation in Python) is an object-oriented, process-based discrete-event simulation language completely implemented in Python. It is released under the GNU Lesser GPL (LGPL). SimPy provides the modeler with components of a simulation model including processes, for active components like customers, messages, and vehicles, and resources, for passive components that form limited capacity congestion points like servers, checkout counters, and tunnels. It also provides monitor variables to aid in gathering statistics. Random variates are provided by the standard Python random module. Many users claim that SimPy is one of the cleanest, easiest to use discrete event simulation packages! SimPy is in use at many universities, Research institutes and in industry. SimPy comes with data collection capabilities, GUI and plotting packages. It can be easily interfaced to other packages, such as plotting, statistics, GUI, spreadsheets, and data bases. The distribution contains extensive documentation (manuals, cheatsheet, tutorials, HTML-based source code documentation) and a wide variety of simulation models in SimPy. Download, enjoy, and don't forget to give us feedback! Klaus Müller Tony Vignaux

itools 0.12.5 released
by "J. David Ibáñez" 14 Mar '06

14 Mar '06

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 itools is a Python library, it groups a number of packages into a single meta-package for easier development and deployment: itools.catalog itools.i18n itools.web itools.cms itools.ical itools.workflow itools.csv itools.resources itools.xhtml itools.datatypes itools.rss itools.xliff itools.gettext itools.schemas itools.xml itools.handlers itools.tmx itools.html itools.uri Changes: URI - Unquote escaped characters when decoding a url. Handlers - Fix virtual handlers (#158). CSV - Now access by attribute works on rows, e.g. "row.<name>", where name is the column name (of course only works when the schema is defined). XHTML - Fix "get_content_as_html" when there are non-ascii characters in text nodes, by encoding them. Web - Now the request handler keeps the whole request uri (not only the path), this is: "request.uri" instead of "request.path". - For virtual hosting, use the request header "X-Base-Path" instead of the query variable REAL_PATH. So rewrite rules must be updated (in Apache this is done with the "RequestHeader set X-Base-Path <value>" line). CMS - Remove consistency check in "Group.get_usernames" (it was an scalability bottleneck). Instead add a view in the user interface to check and fix groups with users that don't exist anymore. Packaging - Provide "itools.__version__" (replaces "itools.__git_revision__"). - Drop the Changelog file. Resources - --------- Download http://www.ikaaro.org/download/itools/itools-0.12.5.tar.gz Home http://www.ikaaro.org/itools Mailing list http://in-girum.net/mailman/listinfo/ikaaro Bug Tracker http://bugs.lleu.org -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2.2 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFEFoxHqTbdUBYy+tIRArd/AJ4wUaiaxM10jX4gOXQjyNe9HGLYLwCgho1Y uEfUx/r0vO5+kIeDKaxuRDg= =Xbuq -----END PGP SIGNATURE-----

An Efficient Scalar Class in Python
by uymqlp502＠sneakemail.com 13 Mar '06

13 Mar '06

A Python class called "scalar" was designed to represent physical scalars and to eliminate errors involving implied physical units (e.g., confusing angular degrees and radians). The standard arithmetic operators are overloaded to provide syntax identical to that for built-in numerical types. The scalar class allows the user to easily define a set of appropriate physical units for any particular application or domain, and the units used internally are based on those selected by the user. Once an application has been developed and tested, the units can easily be switched off, if desired, to achieve the execution efficiency of built-in numerical types (which can be two orders of magnitude faster). The scalar class can also be used for discrete units to enforce type checking of integer counts, thereby enhancing the built-in dynamic type checking of Python. I think you'll like it. Check it out and let me know if I'm right. And let me know if you have any problems. I've tested it to some extent, and I think it's in good shape, but I'd like to get some feedback from other users before I upgrade the beta version to a 1.0 release. Thanks. Go to http://RussP.org/scalar.htm to download the user guide and the code.

ANNOUNCE: PyGObject 2.10.0
by Johan Dahlin 13 Mar '06

13 Mar '06

I am pleased to announce version 2.10.0 of the Python bindings for GObject. The new release is available from ftp.gnome.org as and its mirrors as soon as its synced correctly: http://ftp.gnome.org/pub/GNOME/sources/pygobject/pygobject-2.10.0.tar.gz What's new since PyGObject 2.9.1: - enum/flags leak fix (Michael Smith) Blurb: GObject is a object system library used by GTK+ and GStreamer. PyGObject provides a convenient wrapper for the GObject+ library for use in Python programs, and takes care of many of the boring details such as managing memory and type casting. When combined with PyGTK, PyORBit and gnome-python, it can be used to write full featured Gnome applications. Like the GObject library itself PyGObject is licensed under the GNU LGPL, so is suitable for use in both free software and proprietary applications. It is already in use in many applications ranging from small single purpose scripts up to large full featured applications. PyGObject requires GObject >= 2.8.0 and Python >= 2.3.5 to build. Bug reports, as always, should go to Bugzilla; check out http://www.pygtk.org/developer.html and http://www.pygtk.org/feedback.html for links to posting and querying bug reports for PyGTK. -- Johan Dahlin johan(a)gnome.org _______________________________________________ gnome-announce-list mailing list gnome-announce-list(a)gnome.org http://mail.gnome.org/mailman/listinfo/gnome-announce-list

Announcing edupython list
by Anna Ravenscroft 13 Mar '06

13 Mar '06

In order to facilitate small groups working on specific Python-in-Education projects, we have launched an edupython list on google groups (http://groups.google.com/group/edupython or edupython(a)googlegroups.com). We envision participation by people trying to coordinate work on the nuts and bolts implementation of a project, with frequent progress reports and requests for suggestions and comments coming back to edu-sig. The list developed as a result of a quite well-attended and enthusiastic BOF meeting at PyCon. This edupython list is not intended to replace edu-sig, which remains very strong for theoretical and philosophical discussions, and for getting input and suggestions from a wider group, but is also necessarily higher bandwidth. We invite anyone working on Python-related education projects to join the list. Cordially, Anna Martelli Ravenscroft

Champaign-Urbana (Central Illinois) Python User Group?
by mbbx6spp 13 Mar '06

13 Mar '06

Hi, == Existence of Local User Groups == I am in the process of forming a Python User Group for Champaign-Urbana and surrounding areas, but I would like to make sure there is not already a very unpublicized (very, very hard to find) user group for Python in the area (Decatur, Bloomington or C-U areas)? Please reply to this message (off the group, unless you would like it on the record that there is a group and give general information for other CU Python-heads that may not know about it). I did searches on google, google groups and checked the python.org LocalUserGroup wiki page, but found nothing that was active. The nearest PyUG I found was ChiPy (the Chicago group), which is 2.5 hours drive away. == New Local User Group Status == I am in the process of creating the website (in Python of course:) and should have this ready by Friday 03/17/2006 (St. Paddy's Day), but I did want to make sure there is not anything out there already to avoid duplicate efforts. To be notified on new developments with the user group (events, projects, etc.) please subscribe to the low-traffic Google Group I created today: http://groups.google.com/group/illipy-announce I was also planning on advertizing the first meeting locally in weekly newspapers, and posting flyers across campus and downtown Champaign as well as Urbana retail locations in the next two weeks after the website was launched, and of course listing the website on the python.org wiki and related websites. == First Meeting == Tentative date for the first meeting is Wednesday April 26, 2006 @ 7pm at Giuliani's (where the old Green Street Coffee Shop used to be - 608 E. Green St., Champaign - do not confuse this with the new Green Street Cafe near the Green and First St. intersection). == Other == If anyone has any thoughts or experience with best practices (or potential pitfalls to avoid) to organize (legally) or promote a local user group for Python (or similar special interest groups), please reply to this message (off the group). Thanks, Su

[ANN] DOPAL 0.56 - Python library for Azureus
by Allan Crooks 12 Mar '06

12 Mar '06

Summary: ------- DOPAL is a library to allow programs written in Python to easily communicate the Java BitTorrent client Azureus, via the XML/HTTP plugin (allowing communication over a network). Changes: ------- Version 0.56 is the third public release of DOPAL. One of the main changes is support for "typeless" objects - this allows DOPAL to represent remote objects which it has no information about. There is also support for passing and receiving Java's "short" primitive type, and a fix for a traceback occurring in the __str__ methods of some objects. There's also various other minor changes - check the changelog for more information. The method definitions in this release are in sync with Azureus 2.4.0.1 b13 (though you can use any version of Azureus with DOPAL). Description: ----------- It provides a very Pythonic way of interacting with the objects available in Azureus's Plugin API - you can interact with remote objects and invoke methods on them as easily as any normal Python object (while all the connection handling and XML generation and parsing is done behind the scenes). It also allows you to write code which can do just the same things as Java plugins for Azureus can (well, almost). Website: ------- http://dopal.sourceforge.net/ Example usage: ------------- http://dopal.sourceforge.net/examples.html

by Nemesis 12 Mar '06

12 Mar '06

XPN (X Python Newsreader) is a multi-platform newsreader with Unicode support. It is written with Python+GTK. It has features like scoring/actions, X-Face and Face decoding, muting of quoted text, newsrc import/export, find article and search in the body, spoiler char/rot13, random taglines and configurable attribution lines. You can find it on: http://xpn.altervista.org/index-en.html or http://sf.net/projects/xpn Changes in this release: * added message-id recognition. Now XPN tries to recognize message-ids in the text and make them clickable in order to open a search window. * added a dialog window that informs you when XPN downloads new articles in watched threads. * some improvements in Global Search, now is possible to perform multiple searches. * now XPN checks if there are other istances running (it uses the file xpn.lock in the XPN directory). This behaviour should prevent database break off. * some fixes in the Score Window * fixed some bugs in header management * fixed a bug that caused crashes with multipart articles with email attached XPN is translated in Italian French and German, if you'd like to translate it in your language and you are familiar with gettext and po-files editing please contact me (xpn(a)altervista.org). -- No wanna work. Wanna bang on keyboard. |\ | |HomePage : http://nem01.altervista.org | \|emesis |XPN (my nr): http://xpn.altervista.org

ANNOUNCE: kiwi 1.9.7
by Johan Dahlin 11 Mar '06

11 Mar '06

New in this released is API documentation which is generated using epydoc[3]. It's still being written but at this point I feel that it's good enough to be a very useful resource to help understand kiwi. Kiwi is a PyGTK framework for building graphical applications loosely based on MVC Model-View-Controller (MVC) and Allen Holub's Visual proxy [1]. Think of Kiwi as a high-level, object-oriented layer built on PyGTK. Its design is based on real-world experience using PyGTK to develop large desktop applications, which use many concepts common to most graphical applications: multiple windows and dialogs, forms, data persistence, lists and high-level classes that support domain objects directly. Download ======== Grab the latest sources from: http://www.async.com.br/projects/kiwi/download/kiwi-1.9.7.tar.gz What's new since 1.9.6? ======================= - Much improved mask support - DateEntry widget - Re-add ProxyDelegate (lost since kiwi1) - Draw validation icon on the left side for right align entries - Many ComboEntry bug fixes - Distribution helper improvements - Limited support for zope.interfaces - Add a better HIG alert dialog - Improved logging (a la GStreamer) Features ======== * An MVC-derived framework of classes: * Views, which represent the graphical display * Controllers, which handles user interaction with the widgets in a View. * Delegates, combines a View and a Controller. * Models, which are special mixins for your domain objects * Proxies, special types of Delegate designed to implement forms * Validation: Kiwi supports validation on different levels: data type validation and verification on the Model/Proxy level, View validation and hooks for visually displaying validation state. * ObjectList widget, which provides a higher level abstraction of GtkTreeView and all its classes (GtkTreeModel, GtkTreeViewColumn, GtkCellRenderer) with hooks to easily integrate into the Kiwi Framework. * Mask suport: You can set a mask on entries to force the input to follow a certain standard, such as zip code, social security, ip address * Gazpacho integration for most (non-deprecated) interactive widgets with attributes for handling validation and proxy attributes. * UI Test framework Features a recorder and a player. The recorder allows you to record different tasks, a script will be saved which will reproduce the actions you made in the interface. * Kiwi Tasklets Tasklet is a small coroutines framework written by Gustavo Carneiro, it was previously known as gtasklets. * PyGTK utilities, to make it easier to add signals and properties to your objects. * i18n translation utilities, to help you translate PyGTK applications, currently depends on gettext and intltool. * and many other things! Requirements ============ Python 2.3 or higher (2.4 recommended) http://www.python.org/ PyGTK 2.6.0 or higher (2.8 recommended) http://www.pygtk.org/ gazpacho 0.6.2 (svn recommenced) http://gazpacho.sicem.biz/ Documentation ============= Kiwi provides API documentation generated by epydoc, it can be found at http://www.async.com.br/projects/kiwi/api/ Included in the tarball are also a number of examples, which serves as a good starting point. Keep in mind that most of them require gazpacho to be installed.
