[ANN] PyInstaller 1.1 released
by Giovanni Bajo 13 Feb '06

13 Feb '06

PyInstaller 1.1 *************** PyInstaller 1.1 has been released! This release has been composed also with the help of patches provided by the community: many thanks to everybody! Find the downloads at the usual locations: http://pyinstaller.hpcf.upr.edu (website) http://pyinstaller.hpcf.upr.edu/source/1.1/pyinstaller_1.1.zip http://pyinstaller.hpcf.upr.edu/source/1.1/pyinstaller_1.1.tar.gz ChangeLog for this release: + (Windows) Make single-file packages not depend on MSVCRT71.DLL anymore, even under Python 2.4. You can eventually ship your programs really as single-file executables, even when using the newest Python version! + Fix problem with incorrect python path detection. Now using helpers from distutils. + Fix problem with rare encodings introduced in newer Python versions: now all the encodings are automatically found and included, so this problem should be gone forever. + Fix building of COM servers (was broken in 1.0 because of the new build system). + Mimic Python 2.4 behaviour with broken imports: sys.modules is cleaned up afterwise. This allows to package SQLObject applications under Windows with Python 2.4 and above. + Add import hook for the following packages: + GTK + PyOpenGL (tested 2.0.1.09) + dsnpython (tested 1.3.4) + KInterasDB (courtesy of Eugene Prigorodov) + Fix packaging of code using "time.strptime" under Python 2.3+. + (Linux) Ignore linux-gate.so while calculating dependencies (fix provided by Vikram Aggarwal). + (Windows) With Python 2.4, setup UPX properly so to be able to compress binaries generated with Visual Studio .NET 2003 (such as most of the extensions). UPX 1.92+ is needed for this. -- Giovanni Bajo

py2exe 0.6.4 released
by Jimmy Retzlaff 13 Feb '06

13 Feb '06

py2exe 0.6.4 released ===================== py2exe is a Python distutils extension which converts Python scripts into executable Windows programs, able to run without requiring a Python installation. Console and Windows (GUI) applications, Windows NT services, exe and dll COM servers are supported. Changes in 0.6.4: * New skip-archive option which copies the Python bytecode files directly into the dist directory and subdirectories - no archive is used. * An experimental new custom-boot-script option which allows a boot script to be specified (e.g., --custom-boot-script=cbs.py) which can do things like installing a customized stdout blackhole. See py2exe's boot_common.py for examples of what can be done. The custom boot script is executed during startup of the executable immediately after boot_common.py is executed. * Thomas Heller's performance improvements for finding needed modules. * Mark Hammond's fix for thread-state errors when a py2exe created executable tries to use a py2exe created COM DLL. Changes in 0.6.3: * First release assembled by py2exe's new maintainer, Jimmy Retzlaff. Code changes in this release are from Thomas Heller and Gordon Scott. * The dll-excludes option is now available on the command line. It was only possible to specify that in the options argument to the setup function before. The dll-excludes option can now be used to filter out dlls like msvcr71.dll or even w9xpopen.exe. * Fix from Gordon Scott: py2exe crashed copying extension modules in packages. Changes in 0.6.2: * Several important bugfixes: - bundled extensions in packages did not work correctly, this made the wxPython single-file sample fail with newer wxPython versions. - occasionally dlls/pyds were loaded twice, with very strange effects. - the source distribution was not complete. - it is now possible to build a debug version of py2exe. Changes in 0.6.1: * py2exe can now bundle binary extensions and dlls into the library-archive or the executable itself. This allows to finally build real single-file executables. The bundled dlls and pyds are loaded at runtime by some special code that emulates the Windows LoadLibrary function - they are never unpacked to the file system. This part of the code is distributed under the MPL 1.1, so this license is now pulled in by py2exe. * By default py2exe now includes the codecs module and the encodings package. * Several other fixes.

ANN: Proposals due today, Feb. 13th, for OSCON 2006 (Python 14)
by Kevin Altis 13 Feb '06

13 Feb '06

Save the date for the 8th annual O'Reilly Open Source Convention, happening July 24-28, 2006 at the Oregon Convention Center in beautiful Portland, Oregon. Call For Participation ---------------------- Submit a proposal-fill out the form at: http://conferences.oreillynet.com/cs/os2006/create/e_sess/ Important Dates: * Proposals Due: Midnight (PST) February 13, 2006 * Speaker Notification: March 27, 2006 * Tutorial Presentation Files Due: June 12, 2006 * Session Presentation Files Due: June 26, 2006 * Conference: July 24-28, 2006 Proposals --------- We are considering proposals for 45 minute sessions and 3 hour tutorials. We rarely accept 90 minute proposals, as most general sessions are 45 minutes in length. Your proposals are examined by a committee which draws from them and which also solicits proposals to build the program. Proposals are due by midnight (PST), Feb. 13, 2006. The OSCON Speaker Manager, Vee McMillen, emails notification of the status of your talk (accepted or otherwise) by March 27, 2006. Unless the content of your talk is particularly timely (e.g., features of a product that will be launched at OSCON), you are required to send us your slides several weeks before the conference begins. Submit proposals via the form below. Some tips for writing a good proposal for a good talk: * Keep it free of marketing: talk about open source software, but not about a commercial product--the audience should be able to use and improve the things you talk about without paying money * Keep the audience in mind: they're technical, professional, and already pretty smart. * Clearly identify the level of the talk: is it for beginners to the topic, or for gurus? What knowledge should people have when they come to the talk? * Give it a simple and straightforward title: fancy and clever titles make it harder for people (committee and attendees) to figure out what you're really talking about * Limit the scope of the talk: in 45 minutes, you won't be able to cover Everything about Widget Framework X. Instead, pick a useful aspect, or a particular technique, or walk through a simple program. * Pages of code are unreadable: mere mortals can deal with code a line at a time. Sometimes three lines at a time. A page of code can't be read when it's projected, and can't be comprehended by the audience. * Explain why people will want to attend: is the framework gaining traction? Is the app critical to modern systems? Will they learn how to deploy it, program it, or just what it is? * Let us know in your proposal notes whether you can give all the talks you submitted proposals for * Explain what you will cover in the talk NOTE: All presenters whose talks are accepted (excluding Lightning Talks) will receive free registration at the conference. For each half-day tutorial, the presenter receives one night's accommodation, a limited travel allowance, and an honorarium. We give tutors and speakers registration to the convention (including tutorials), and tutors are eligible for a travel allowance: up to US$300 from the west coast of the USA, up to US$500 from the east coast of the USA, up to US$800 from outside the USA. Registration opens April, 2006. If you would like to be notified by email when registration opens, please use the form on our main page. CONFERENCE INFO =============== The O'Reilly Open Source Convention is where coders, sysadmins, entrepreneurs, and business people working in free and open source software gather to share ideas, discover code, and find solutions. At OSCON 2005, more than 2,400 attendees took part in 241 sessions and tutorials across eleven technology tracks, learning about the newest features and versions from creators and experts. A record number of products launches and announcements were made, and sponsors and exhibitors from a wide range of companies filled the largest exhibit hall in OSCON's history. We anticipate that OSCON 2006 will be even more successful, and continue to be the place for the open source community to meet up, debate, make deals, and connect face to face. OSCON 2006 will take place at the Oregon Convention Center in Portland, Oregon July 24-28, 2006. OSCON 2006 will feature the projects, technologies, and skills that you need to write and deploy killer modern apps. We're looking for proposals on platforms and applications around: * Multimedia including voice (VoIP) and video * AI including spam-busting, classification, clustering, and data mining * Collaboration including email, calendars, RSS, OPML, mashups, IM, presence, and session initialization * Project best practices including governance, starting a project, and managing communities * Microsoft Windows-based open source projects including .NET, Mono, and regular C/C++/Visual Basic Windows apps * Enterprise Java techniques including integration, testing, and scalable deployment solutions * Linux kernel skills for sysadmins including virtualization, tuning, and device drivers * Device hacking including iPods, Nintendo, PSP, XBox 360, and beyond * Design including CSS, GUI, and user experience (XP) * Entrepreneurial topics including management for techies, how to go into business for yourself, and business models that work * Security including hardening, hacking, root kits (Sony and otherwise), and intrusion detection/cleanup * Fun subjects with no immediate commercial application including retro computing, games, and BitTorrent Tracks at OSCON will include: * Desktop Apps * Databases, including MySQL, PostgreSQL, Ingres, and others * Emerging Topics * Java * Linux Kernel for SysAdmins * Linux for Programmers * Perl, celebrating the 10th year of The Perl Conference! * PHP * Programming, including everything that's not specific to a particular language * Python * Security * Ruby, including Ruby on Rails * Web Apps, including Apache * Windows

ANN: first release of IVuPy-0.1
by Gerard Vermeulen 12 Feb '06

12 Feb '06

I am proud to announce IVuPy-0.1 (I-View-Py). IVuPy is a Python extension module developed to write Python programs for 3D visualization of large data sets using Qt and PyQt. Python is extended by IVuPy with more than 600 classes of two of the Coin3D C++ class libraries: Coin and SoQt. Coin is compatible with the Open Inventor API. Open Inventor is an object-oriented 3D toolkit built on OpenGL that provides a 3D scene database, a built-in event model for user interaction, and the ability to print objects and exchange data with other graphics formats. The SoQt library interfaces Coin to Qt. See http://www.coin3d.org for more information on Coin3D. IVuPy requires at least one of the Numerical Python extension modules: NumPy, Numeric, or numarray (IVuPy works with all of them at once). Data transfer between the Numerical Python arrays and the Coin data structures has been implemented by copying. The design of the Open Inventor API favors ease of use over performance. The API is a natural match for Python, and in my opinion it is fun to program with IVuPy. The performance penalty of the design choice is small. The first example at http://ivupy.sourceforge.net/examples.html demonstrates this: NumPy calculates a surface with a million nodes in 1.7 seconds and Coin3D redisplays the surface in 0.3 seconds on my Linux system with a 3.6 GHz Pentium and a nVidea graphics card (NV41.1). The Inventor Mentor ( http://www.google.com/search?q=inventor+mentor ) is essential for learning IVuPy. The IVuPy documentation supplements the Inventor Mentor. IVuPy includes all C++ examples from the Inventor Mentor and their Python translations. There are also more advanced examples to show the integration of IVuPy and PyQt. IVuPy has been used for almost 6 months on Linux and Windows in the development of a preprocessor for a finite element flow solver and has been proven to be very stable. Prerequisites for IVuPy are: - Python-2.4.x or -2.3.x - at least one of NumPy, numarray, or Numeric - Qt-3.3.x, -3.2.x, or -3.1.x - SIP-4.3.x or -4.2.1 - PyQt-3.15.x or -3.14.1 - Coin-2.4.4 or -2.4.3 - SoQt-1.3.0 or -1.2.0 IVuPy is licensed under the terms of the GPL. Contact me, if the GPL is an obstacle for you. http://ivupy.sourceforge.net is the home page of IVuPy. Have fun -- Gerard Vermeulen

ANN: PyGUI 1.6
by greg 12 Feb '06

12 Feb '06

PyGUI 1.6 is now available: http://www.cosc.canterbury.ac.nz/~greg/python_gui/ The major change in this version is that the Mac version is based on Cocoa instead of Carbon. This should provide a much better base for future development, but it does mean that MacOSX will now be required. (This isn't as big a change as it seems, since the Carbon version actually required MacOSX too, despite being Carbon.) There have been numerous other changes and improvements as well. See the CHANGES file in the distribution or on the web site for full details. What is PyGUI? -------------- PyGUI is an experimental highly-Pythonic cross-platform GUI API. Implementations are currently available for MacOSX and Gtk. For a full description of the project goals, see the PyGUI web page at the above address.
