ANNOUNCE: KirbyBase 1.8
by Jamey Cribbs Feb. 20, 2005

Feb. 20, 2005

KirbyBase is a simple, plain-text, database management system written in Python. It can be used either embedded in a python script or in a client/server, multi-user mode. You use python code to express your queries instead of having to use another language such as SQL. KirbyBase is disk-based, not memory-based. Database changes are immediately written to disk. You can find more information on KirbyBase at: http://www.netpromi.com/kirbybase.html You can download KirbyBase for Python at: http://www.netpromi.com/files/KirbyBase_Python_1.8.zip The most noticeable things about this release are (1) the ability to sort the result set by multiple fields, (2) the ability to have the result set returned as a nicely formatted report, suitable for printing, and (3) the ability to do an insert or an update using a record object (thanks, Fred Pacquier, for the suggestion). The manual has also been updated to reflect the new features. Also, for those of you who have asked how Kirby is doing, I have a couple of new pictures of him on the website. :-) I would like to thank everyone who has emailed me with comments, bug reports, and enhancement requests/ideas. Hearing from people who actually use KirbyBase is what makes working on it worthwhile. Please keep the emails coming! Changes in Version 1.8: ******** IMPORTANT - Method Interface Changes **************** -Added the ability to sort the result set of a select by multiple fields and to specify whether each field should be sorted ascending or descending. This necessitated a change to the interface of the select method. I moved the position of sortField in the argument list and also changed it to be a list instead of a string. I also changed the name of sortField to sortFields. I also moved sortDesc in the arguement list and also made it a list. ****************************************************************** -Added another allowable value, 'report', to the keyword parameter, returnType in the select method. This returns the result set in a pretty print format. Along with this, added another keyword parameter called rptSettings to the select method. This is only used if rptType is 'report'. It is a 2 element list. The first element specifies the number of records to print on a page. The second element is boolean specifying whether to print a dashed line between records. -Added ability to pass field values to update and insert using an object with attributes set equal to the field names. -Fixed a bug in _getMatches. If a field of type int or float had a blank value in the table (i.e. ''), the code was attempting to convert it to it's proper type (i.e. int or float) before doing the match comparison. This would cause an exception to occur. Now, if the field is an int,float,date or datetime and it is blank, I convert it to None. This allows the numeric comparisons to work correctly for null fields. -Fixed a bug in select. If a field in the result set was equal to '', I was letting it stay that way, when I should really be converting it to None before returning the result set. -Cleaned up the internals a bit. Mainly, I tried to use functions in the operator module like lt and ge instead of hardcoding < and >= in an if statement. Jamey Cribbs jcribbs(a)twmi.rr.com

PyQt Python Bindings for Qt v3.14 Released
by Phil Thompson Feb. 20, 2005

Feb. 20, 2005

Riverbank Computing is pleased to announce the release of PyQt v3.14 available from http://www.riverbankcomputing.co.uk/. Changes since the last release include support for QScintilla v1.5. PyQt is a comprehensive set of Qt bindings for the Python programming language and supports the same platforms as Qt. Like Qt, PyQt is available under the GPL (for UNIX, Linux and MacOS/X), a commercial license (for Windows, UNIX, Linux and MacOS/X) and a free educational license (for Windows). PyQt is implemented as a set of 9 extension modules containing 300 classes and over 5,750 functions and methods. PyQt also includes bindings to QScintilla, the port to Qt of the Scintilla editor component. PyQt can be used either as a rapid prototyping tool, or as an alternative to C++ for developing large Qt applications. PyQt includes the pyuic utility which generates Python code to implement user interfaces created with Qt Designer in the same way that the uic utility generates C++ code. Third party tools are also available - such as eric3, a comprehensive IDE (including an editor, debugger, class browser, integration with Qt Designer, re-factoring tools, unit testing tools and integration with source code control systems). eric3 is written entirely using PyQt and is available from http://www.die-offenbachs.de/detlev/eric3.html.

[ANN] mlabwrap v0.9b3
by Alexander Schmolck Feb. 18, 2005

Feb. 18, 2005

I have recently uploaded mlabwrap v0.9b3, a high-level python to matlab(tm) bridge, you can get it from <http://mlabwrap.sourceforge.net/> It should work with recent python >=2.3 and matlab(tm) >=6.0; I've used it extensively myself but this is the first announcement to a wider public -- so I'd very much like to hear some feedback (even if it's just "works fine"). Here is a short demo snippet: >>> from mlabwrap import mlab >>> import Numeric >>> mlab.lookfor('singular value') GSVD Generalized Singular Value Decompostion. SVD Singular value decomposition. [...] >>> help(mlab.svd) mlab_command(*args, **kwargs) SVD Singular value decomposition. [U,S,V] = SVD(X) produces a diagonal matrix S, of the same dimension as X and with nonnegative diagonal elements in [...] >>> mlab.svd(array([[1,2], [1,3]])) array([[ 3.86432845], [ 0.25877718]]) 'as

[ANN] Release 0.22 of Task Coach
by Frank Niessink Feb. 17, 2005

Feb. 17, 2005

Hi all, I am pleased to announce release 0.22 of Task Coach. New in this release: Bugs fixed: - In the effort summary view, effort spent on a task in the same month or week but in different years would erroneously be added. E.g. effort in January 2004 and January 2006 would be added. - The mechanism to prevent effort periods with a negative duration (i.e. a start time later than the stop time) in the effort editor was invoked on each key stroke which caused inconvenient behaviour. Fixed it by only invoking it when the user leaves the text or combo box. Features added: - Added possibility to start tracking effort for a task, with start time equal to the end time of the previous effort period. This is for example convenient if you stop working on a task and then spend some time deciding on what to do next. This is the 'Start tracking from last stop time' menu item in the 'Effort' menu. - (Re)Added the unittests to the source distribution. See INSTALL.txt. - Export to XML. Currently limited to tasks, effort is not exported yet. What is Task Coach? Task Coach is a simple task manager that allows for hierarchical tasks, i.e. tasks in tasks. Task Coach is open source (GPL) and uses wxPython. You can download Task Coach from: http://taskcoach.niessink.com. A binary installer is available for Windows XP, in addition to the source distribution. Thanks, Frank

[ANN] PyComicsViewer 0.9.9
by ionutz Feb. 17, 2005

Feb. 17, 2005

PyComicsViewer-0.9.9 has been released. What is PyComicsViewer? ======================= Is a comics viewer written in python, PyGTK and PIL. I made it as I didn't fully like any of the existing viewers and I wanted something that works the same (nice) way on both Linux and Windows. Because of the way it was implemented, you can also use it like a kind of image browser/viewer, but this is not its primary destination. Browsing images from uncompressed directories is provided because resulted naturally from the implementation and because I've seen some people that distribute their scaned comics uncompressed. Changes in 0.9.9 (2005/02/17) ============================= * finished the implementation of panning and mouse navigation * added a thumb preview page to the browser Licensing ========= PyComicsViewer is released under the GPL. Where can I get it? =================== Home page: http://borco.net/html/PyComicsViewer/ Downloads: http://borco.net/html/PyComicsViewer/PyComicsViewer-0.9.9.tar.gz http://borco.net/html/PyComicsViewer/PyComicsViewer-0.9.9.zip http://borco.net/html/PyComicsViewer/PyComicsViewer-0.9.9.win32-py2.4.exe Cheers,
