ANN: Phebe 0.1
by Thomas Lotze Dec. 26, 2006

Dec. 26, 2006

Phebe 0.1 has been released and uploaded to the Python package index. >From README.txt: ========================================================================= Phebe comprises a Python package and a number of executable scripts to operate a mobile phone connected to your computer. The implementation follows the Sony-Ericsson developer guidelines for using AT commands as of December 7, 2006, see <http://developer.sonyericsson.com/getDocument.do?docId=65054>. It has been tested only on a SE K750i, using Debian and Gentoo Linux distributions with a 2.6 kernel so far. The current status of Phebe is "works for me", i.e. it provides the functionality the author immediately needs: get usage stats of the phone, back-up the phonebook, dump and delete short messages. See ROADMAP.txt and TODO.txt for prospective further developments. While neither talking through the AT command interface nor the higher-level data structures implemented by Phebe are operating system specific, communication with the device is. Phebe currently does this by using a Python module only available on Unix. The author is not going to port Phebe to non-Unix systems any time soon, so if you want it to support your OS, you have to supply an appropriate patch. Phebe was written by Thomas Lotze. Please contact the author at <thomas(a)thomas-lotze.de> to provide feedback or suggestions on or contributions to Phebe. ========================================================================= Phebe requires Python 2.5. The Phebe code base is maintained in a subversion repository at <https://svn.thomas-lotze.de/repos/public/Phebe>. There is a ViewCVS view on the repository available at <http://svn.thomas-lotze.de/public/Phebe>. -- Thomas

[ANN] ftputil 2.2 released
by Stefan Schwarzer Dec. 24, 2006

Dec. 24, 2006

ftputil 2.2 is now available from http://ftputil.sschwarzer.net/download . Changes since version 2.1 ------------------------- - Results of stat calls (also indirect calls, i. e. listdir, isdir/isfile/islink, exists, getmtime etc.) are now cached and reused. This results in remarkable speedups for many use cases. Thanks to Evan Prodromou for his permission to add his lrucache module under ftputil's license. - The current directory is also locally cached, resulting in further speedups. - It's now possible to write and plug in custom parsers for directory formats which ftputil doesn't support natively. - File-like objects generated via ``FTPHost.file`` now support the iterator protocol (for line in some_file: ...). - The documentation has been updated accordingly. Read it under http://ftputil.sschwarzer.net/trac/wiki/Documentation . Possible incompatibilities: - This release requires at least Python 2.3. (Previous releases worked with Python versions from 2.1 up.) - The method ``FTPHost.set_directory_format`` has been removed, since the directory format (Unix or MS) is set automatically. (The new method ``set_parser`` is a different animal since it takes a parser object to parse "foreign" formats, not a string.) 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. License ------- ftputil 2.2 is Open Source software, released under the revised BSD license (see http://www.opensource.org/licenses/bsd-license.php ). Stefan -- Dr.-Ing.

ANN: PyTables 1.4 (A Hierarchical Database) released!
by Francesc Altet Dec. 21, 2006

Dec. 21, 2006

=========================== Announcing PyTables 1.4 =========================== PyTables is a library for managing hierarchical datasets and designed to efficiently cope with extremely large amounts of data with support for full 64-bit file addressing. It is based on the HDF5 library for doing the I/O and leverages the numarray/NumPy/Numeric packages so as to deliver the data to the end user in convenient in-memory containers. This is a new major release of PyTables, and probably the last major one of the 1.x series (i.e. with numarray at the core). On it, we have implemented better code to deal with table buffers, enhanced the capability for reading native HDF5 files, enhanced support for 64-bit platforms (but not with Python 2.5: see ``Special Warning`` section below), better support for AIX, optional automatic parent creation and the traditional amount of bug fixes. Go to the PyTables web site for downloading the beast: http://www.pytables.org/ or keep reading for more info about the new features and bugs fixed. Changes more in depth ===================== Improvements: - Table buffers code refactored: now each Row read iterator has its own buffers, completely independent of their table (although write iterators still share a single buffer in the same table). This separation makes the logic of buffering much more clear and less prone to errors (in fact, some of them have been solved). Performance and memory consumption are more or less equal than before. - When flushing the complete file (i.e. when calling File.flush()), only the buffers of those nodes that are alive (i.e. referenced from user code) are actually flushed. This brings much better efficiency (and also stability) to situations where one has to flush (and hence, close) files with many nodes on it. - Better support for AIX by renaming the internal LONLONG_MAX C constant (it was used internally by the xlc compiler). Thanks to Brian Granger for the report. - Added optional automatic parent creation support during node creation, copying and moving operations. See the release notes for more information. - Improved support for Python2.4 and 64-bit platforms (but beware, there are still known issues when using Python2.5 in combination with 64-bit platforms). Thanks to Gerard Vermeulen for his patches for Win64 platforms. - Implemented a workaround for a leak present in numarray --> Numeric conversions when using the array protocol, as can be seen in: http://comments.gmane.org/gmane.comp.python.numeric.general/12563 The workaround can potentially be far slower than the array protocol (because a copy of the arrays is always made), but at least the new code doesn't leak anymore. Bug fixes: - Previously, when the size for memory compounds type was less than the size of the type on disk (for example, when one have padding or aligned fields), PyTables was unable to read info on them. This has been fixed. This allows reading general compound types in HDF5 files written with other tools than PyTables. - When many tables with indexed columns were created simultaneously, a bug make PyTables to crash. This has been fixed (for more info, see bug #26). - Fixed a typo in the code that prevented recognizing complex data in non-PyTables files. - Table.createIndex() now refuses to index complex columns. - Now, it is possible to index several nested columns that hangs from the same column parent. Fixes bug #24. - Fixed a typo in nctoh5 utility that prevented using filters properly. Thanks to Lou Wicker for reporting this. - When setting/appending an array in-memory to an Array (or descendant) object and they have mismatched byteorders, the array was set/appended without being byteswapped first. This has been fixed. Thanks to Elias Collas for the report. Deprecated features: - None Backward-incompatible changes: - Please, see ``RELEASE-NOTES.txt`` file. Special Warning for Python 2.5 and 64-bit platforms users ========================================================= Unfortunately, and due to problems with the combination numarray 1.5.2, Python2.5 and 64-bit platforms, PyTables cannot be safely used yet in such scenario. This will be solved either when numarray can address this issue (hopefully with numarray 1.5.3), or when PyTables 2.x series (with NumPy at its core) will be out. Important note for Windows users ================================ If you are willing to use PyTables with Python 2.4 or 2.5 in Windows platforms, you will need to get the HDF5 library compiled for MSVC 7.1, aka .NET 2003. It can be found at: ftp://ftp.ncsa.uiuc.edu/HDF/HDF5/current/bin/windows/5-165-win-net.ZIP Users of Python 2.3 on Windows will have to download the version of HDF5 compiled with MSVC 6.0 available in: ftp://ftp.ncsa.uiuc.edu/HDF/HDF5/current/bin/windows/5-165-win.ZIP Platforms ========= This version has been extensively checked on quite a few platforms, like Linux on Intel32 (Pentium), Win on Intel32 (Pentium), Linux on Intel64 (Itanium2), FreeBSD on AMD64 (Opteron), Linux on PowerPC (and PowerPC64) and MacOSX on PowerPC. For other platforms, chances are that the code can be easily compiled and run without further issues. Please, contact us in case you are experiencing problems. Resources ========= Go to the PyTables web site for more details: http://www.pytables.org About the HDF5 library: http://hdf.ncsa.uiuc.edu/HDF5/ About numarray: http://www.stsci.edu/resources/software_hardware/numarray About NumPy: http://numpy.scipy.org/ To know more about the company behind the PyTables development, see: http://www.carabos.com/ Acknowledgments =============== Thanks to various the users who provided feature improvements, patches, bug reports, support and suggestions. See the ``THANKS`` file in the distribution package for a (incomplete) list of contributors. Many thanks also to SourceForge who have helped to make and distribute this package! And last but not least, a big thank you to Acusim (http://www.acusim.com/) for sponsoring many of the job done for releasing this version of PyTables. Share your experience ===================== Let us know of any bugs, suggestions, gripes, kudos, etc. you may have. ---- **Enjoy data!** -- The PyTables Team

[ANN] pygtkmvc version 1.0.0 has been released
by Roberto Cavada Dec. 21, 2006

Dec. 21, 2006

Hi all, I'm proud to announce that the first stable release 1.0.0 of pygtkmvc has been released. -------------------------------- ** pygtkmvc version 1.0.0 ** -------------------------------- pygtkmvc is a fully Python-based implementation of the Model-View-Controller (MVC) and Observer patterns for the PyGTK2 toolkit. MVC is a pattern that can be successfully used to design and develop well structured GUI applications. The MVC pattern basically helps in separating semantics and data of the application from their representation. The Observer pattern helps to weaken dependencies among parts that should be separated, but need to be connected each other. pygtkmvc provides a powerful and still simple infrastructure to help designing and implement GUI applications based on the MVC and Observer patterns. -------------------------------- ** Features ** -------------------------------- The framework has been designed to be: - Essential and small, it does only what it was designed for. - Not an external dependency for your application: it fits in 80KB and can be released along with it. - Easy to understand and to use; fully documented. - Portable: straightly runs under many platforms. Version 1.0.0 is the first stable release. Main features are: - Observer pattern supports pythonian containers and user-defined classes. - Support for multi-threading in models. - Support for gtk models like TreeModel and TextBuffer. - Bug fixes. - Documentation and several examples are provided. -------------------------------- ** Get it! ** -------------------------------- Latest version and information can be found at the project home page: <http://pygtkmvc.sourceforge.net> License is LGPL. -------------------------------- ** Credits ** -------------------------------- Many thanks to: - Baruch Even <baruch _AT_ ev-en.org> for providing useful feedback and a pretty example. - Johannes Jordens <j.jordens _AT_ ucl.ac.uk> and Robert Jordens <jordens _AT_ debian.org> for depeloping and maintaining Debian packages. -- Roberto Cavada

new Python-Ideas mailing list
by bcannon＠gmail.com Dec. 20, 2006

Dec. 20, 2006

At Guido's suggestion, a new mailing list has been created named Python-Ideas (http://mail.python.org/mailman/listinfo/python-ideas). This list is meant as a place for speculative, pie-in-the-sky language design ideas to be discussed and honed to the point of practically being a PEP before being presented to python-dev or python-3000. This allows both python-dev and python-3000 to focus more on implementation work or final approval/denial of ideas instead of being flooded with long threads where people discuss ideas that are too nebulous to be considered for inclusion into Python. Like python-dev and python-3000, Python-Ideas requires you subscribe before you can post, but there is no moderator approval required to subscribe. If you are interested in helping me out by being an administrator or moderator for the list, please let me know. -Brett

[ANNOUNCE] Thirty-fifth release of PythonCAD now available
by Art Haas Dec. 20, 2006

Dec. 20, 2006

Hi. I'm pleased to announce the thirty-fifth development release of PythonCAD, a CAD package for open-source software users. As the name implies, PythonCAD is written entirely in Python. The goal of this project is to create a fully scriptable drafting program that will match and eventually exceed features found in commercial CAD software. PythonCAD is released under the GNU Public License (GPL). PythonCAD requires Python 2.2 or newer. The interface is GTK 2.0 based, and uses the PyGTK module for interfacing to GTK. The design of PythonCAD is built around the idea of separating the interface from the back end as much as possible. By doing this, it is hoped that both GNOME and KDE interfaces can be added to PythonCAD through usage of the appropriate Python module. Addition of other PythonCAD interfaces will depend on the availability of a Python module for that particular interface and developer interest and action. The thirty-fifth release contains several improvements dealing with the storage and adjustment of user preferences and image settings. The global user preferences are now saved into a file kept in the user home directory, so the settings are now preserved between PythonCAD sessions. Individual drawing settings can be examined and adjusted via a new set of menus and dialogs. These new dialogs are more complete than the single dialog previously used as well as easier to use. In addition to the preference and setting changes, a variety of bug fixes and miscellaneous code improvements are also present in this new release. A mailing list for the development and use of PythonCAD is available. Visit the following page for information about subscribing and viewing the mailing list archive: http://mail.python.org/mailman/listinfo/pythoncad Visit the PythonCAD web site for more information about what PythonCAD does and aims to be: http://www.pythoncad.org/ Come and join me in developing PythonCAD into a world class drafting program! Art Haas -- Man once surrendering his reason, has no remaining guard against absurdities the most monstrous, and like a ship without rudder, is the sport of every wind. -Thomas Jefferson to James Smith, 1822
