[ANN] first full alpha release of PyLab_Works v0.3
by Stef Mientki 16 Jun '09

16 Jun '09

hello, I am pleased to announce the first full alpha release of PyLab_Works, v0.3. PyLab_Works is a modular Visual Development Environment, based on data-flow programming technics. PyLab_Works is specially aimed at Education, Engineering and Science. The ideas behind PyLab_Works are, that the final user should not be burdened with programming details and domain details, whereas the domain expert should be able to implement the specific domain knowledge without being a full educated programmer. You can always find my notes on PyLab_Works on http://pic.flappie.nl Most of these pages are also collected in a single pdf document, which can be found here: http://pylab-works.googlecode.com/files/pw_manual.pdf The source code and a one-button-Windows-Installer can be found on codegoogle: http://code.google.com/p/pylab-works/ The files are rather large, because they contain some data samples. The Windows-Installer contains everything you need to get started with PyLab_Works: ConfigObj, gprof2dot, HTTPlib, MatPlotLib, Numpy, Pickle, Psyco, pyclbr, PyGame, PyLab_Works, PyODBC, Python, RLCompleter, Scipy, Sendkeys, SQLite3, SQLObject, URLparse, wave, Visual, win32*, wxPython. Although the PyLab_Works programs are compiled with Py2Exe, all the source files are explicitly included. have fun, Stef Mientki

PyQt v4.5.1 Released (Python bindings for Qt)
by Phil Thompson 16 Jun '09

16 Jun '09

PyQt v4.5.1 has been released and is available from http://www.riverbankcomputing.com/software/pyqt/. PyQt is a comprehensive set of bindings for the Qt application and UI framework from Nokia. It supports the same platforms as Qt (Windows, Linux and MacOS/X). The highlights of this release include: - support for Python v3 - support for Qt v4.5 - a new Pythonic API for connecting signals and slots that doesn't require any knowledge of C++ data types - support for the GTK+ theme engine. Windows installers are provided for the GPL version of PyQt which contains everything needed for PyQt development (including Qt, Qt Designer and QScintilla) except Python itself. PyQt v4 is implemented as a set of 18 extension modules containing over 400 classes and over 6,000 functions and methods. QtCore The non-GUI infrastructure including event loops, threads, i18n, Unicode, signals and slots, user and application settings, mapped files and shared memory. QtDesigner A set of classes that allow the Qt Designer GUI design tool to be extended with PyQt. QtGui A rich collection of GUI widgets. QtHelp A set of classes for creating and viewing searchable documentation and being able to integrate online help with PyQt applications. It includes the C++ port of the Lucene text search engine. QtNetwork A set of classes to support TCP and UDP socket programming and higher level protocols (eg. HTTP, SSL). QtOpenGL A set of classes that allows PyOpenGL to render onto Qt widgets. QtScript A set of classes that implements a JavaScript interpreter. Python objects may be exposed in the interpreter as JavaScript objects. QtScriptTools A debugger for the JavaScript interpreter. QtSql A set of classes that implement SQL data models and interfaces to industry standard databases. The Windows installers include support for SQLite, MySQL, PostgreSQL and ODBC. QtSvg A set of classes to render SVG files onto Qt widgets. QtTest A set of classes to automate unit testing of PyQt applications and GUIs. QtWebKit This implements a web browser engine based on the WebKit engine used by Apple's Safari browser. It allows the methods and properties of Python objects to be published and appear as JavaScript objects to scripts embedded in HTML pages. QtXML A set of classes that implement DOM and SAX parsers. QtXMLPatterns A set of classes that implement XQuery and XPath support for XML and custom data models. QtAssistant A set of classes that enables the Qt Assistant online help browser to be integrated with an application. QAxContainer A set of classes for Windows that allows the integration of ActiveX controls and COM objects. phonon A cross-platform multimedia framework that enables the use of audio and video content in PyQt applications. DirectX is used as the Windows backend, QuickTime as the MacOS/X backend, and GStreamer as the Linux backend. DBus PyQt includes dbus.mainloop.qt that allows the Qt event loop to be used with the standard DBus Python bindings. PyQt includes the pyuic4 utility which generates Python code to implement user interfaces created with Qt Designer in the same way that the uic utility generates C++ code. It is also able to load Designer XML files dynamically. PyQt is available under the GPL and a commercial license. Unlike Qt, PyQt is not available under the LGPL. The commercial PyQt license allows GPL applications to be relicensed at any time.

SIP v4.8.1 Released
by Phil Thompson 16 Jun '09

16 Jun '09

SIP v4.8.1 has been released and can be downloaded from http://www.riverbankcomputing.com/software/sip/. SIP is a tool for generating Python modules that wrap C or C++ libraries. It is similar to SWIG. It is used to generate PyQt and PyKDE. SIP is licensed under the Python License and runs on Windows, UNIX, Linux and MacOS/X. SIP requires Python v2.3 or later. The main focus of this release is support for Python v3. Other features of SIP include: - extension modules are implemented as a single binary .pyd or .so file (no Python stubs) - support for Python new-style classes - the ability to specify the super-type and meta-type used to wrap instances - generated modules are quick to import, even for large libraries - thread support - the ability to re-implement C++ abstract and virtual methods in Python - the ability to define Python classes that derive from abstract C++ classes - the ability to spread a class hierarchy across multiple Python modules - support for C++ namespaces - support for C++ exceptions - support for C++ operators - an extensible build system written in Python that supports over 50 platform/compiler combinations - the generation of API files for IDEs that support autocompletion and call tips.

Join us for the 2nd Scientific Computing with Python Webinar
by Travis Oliphant 15 Jun '09

15 Jun '09

Hello all Python users: I am pleased to announce the second installment of a free Webinar series that discusses using Python for scientific computing. Enthought hosts this free series which takes place once a month for about 60-90 minutes. The schedule and length may change based on participation feedback, but for now it is scheduled for the third Friday of every month. This free webinar should not be confused with the EPD webinar on the first Friday of each month which is open only to subscribers to the Enthought Python Distribution at the Basic level or above. This session's speakers will be me (Travis Oliphant) and Peter Wang. I will show off a bit of EPDLab which is an interactive Python environment built using IPython, Traits, and Envisage. Peter Wang will present a demo of Chaco and provide some examples of interactive visualizations that can be easily constructed using it's classes. If there is time after the Chaco demo, I will continue the discussion about Mayavi, but I suspect this will have to wait until the next session. All of the tools we will show are open-source, freely- available tools from multiple sources. They can all be conveniently installed using the Enthought Python Distribution. This event will take place on Friday, June 19th at 1:00pm CDT and will last 60 to 90 minutes depending on the questions asked. If you would like to participate, please register by clicking on the link below or going to https://www1.gotomeeting.com/register/303689873. There will be a 15 minute technical help-session prior to the on-line meeting which you should plan to use if you have never participated in a GoToWebinar previously. During this time you can test your connection and audio equipment as well as familiarize yourself with the GoTo Meeting software (which currently only works with Mac and Windows systems). I am looking forward to interacting with many of you again this Friday. Best regards, Travis Oliphant Enthought, Inc. Enthought is the company that sponsored the creation of SciPy and the Enthought Tool Suite. It continues to sponsor the SciPy community by hosting the SciPy mailing list and website and participating in the development of SciPy and NumPy. Enthought creates custom scientific and technical software applications and provides training on using Python for technical computing. Enthought also provides the Enthought Python Distribution.
