ANNOUNCE: KirbyBase 1.5
by Jamey Cribbs 03 Sep '03

03 Sep '03

KirbyBase 1.5 is now available at: http://www.netpromi.com/files/KirbyBase-1.5.zip What is KirbyBase? KirbyBase is a simple, pure-Python, plain-text, flat-file database management system that can be used either embedded in your application or in a client/server, multi-user mode. To find out more about KirbyBase, go to: http://www.netpromi.com/kirbybase.html Changes: Well after reading some posts on comp.lang.python about how slow eval can be, I set about eliminating eval from KirbyBase. It resulted in uglier code, but increased performance, enough of a performance increase that I figured I would go ahead and release a new version. Specifically, the changes are: Changed the way queries are handled internally. Instead of doing an eval to do numeric and datetime comparisons, I changed it to do the actual comparison itself. This resulted in a 40% speed increase on large queries that do comparison expressions. Changed how data is passed between the server and the client in client/server mode. I now use cPickle instead of repr and eval. This resulted in an approximately 40% speed increase in client/server operations. An anecdotal example, doing a date range select query against a 78,000 record table returning 23,800 records in the result set. Version 1.4: 13 seconds Version 1.5: 8 seconds Who says Python isn't fast? :)

Updated Cygwin Package: python-2.3-2
by Jason Tishler 02 Sep '03

02 Sep '03

New News: === ==== I have updated the version of Python to 2.3-2. The tarballs should be available on a Cygwin mirror near you shortly. Note this package was built against Cygwin 1.5.2-1. Hence, it *is* an official 64-bit, Cygwin 1.5.x package. Old News: === ==== Python is an interpreted, interactive, object-oriented programming language. If interested, see the Python web site for more details: http://www.python.org/ Please read the README file: /usr/doc/Cygwin/python-2.3.README since it covers requirements, installation, known issues, etc. To update your installation, click on the "Install Cygwin now" link on the http://cygwin.com/ web page. This downloads setup.exe to your system. Then, run setup and answer all of the questions. Note that we have recently stopped downloads from sources.redhat.com (aka cygwin.com) due to bandwidth limitations. This means that you will need to find a mirror which has this update. In the US, ftp://mirrors.rcn.net/mirrors/sources.redhat.com/cygwin/ is a reliable high bandwidth connection. In Germany, ftp://ftp.uni-erlangen.de/pub/pc/gnuwin32/cygwin/mirrors/cygnus/ is usually pretty good. In the UK, http://programming.ccp14.ac.uk/ftp-mirror/programming/cygwin/pub/cygwin/ is usually up-to-date within 48 hours. If one of the above doesn't have the latest version of this package then you can either wait for the site to be updated or find another mirror. The setup.exe program will figure out what needs to be updated on your system and will install newer packages automatically. If you have questions or comments, please send them to the Cygwin mailing list at: cygwin(a)cygwin.com . I would appreciate if you would use this mailing list rather than emailing me directly. This includes ideas and comments about the setup utility or Cygwin in general. If you want to make a point or ask a question, the Cygwin mailing list is the appropriate place. *** CYGWIN-ANNOUNCE UNSUBSCRIBE INFO *** If you want to unsubscribe from the cygwin-announce mailing list, look at the "List-Unsubscribe: " tag in the email header of this message.

ANNOUNCE: PyORBit 2.0.0
by James Henstridge 02 Sep '03

02 Sep '03

PyORBit 2.0.0, the Python binding for the ORBit2 CORBA ORB, is now available at: http://ftp.gnome.org/pub/GNOME/sources/pyorbit/2.0/ PyORBit provides both client and server side CORBA bindings, and aims to follow the standard Python language mapping for CORBA (http://www.omg.org/cgi-bin/doc?formal/02-09-07). PyORBit is capable of calling in process servers implemented using ORBit2, and being called by in process C code. This makes it ideal for use in the Gnome environment, and is used by the gnome-python Gnome bindings. PyORBit requires ORBit2 >= 2.4.4 and Python >= 2.2. Questions about PyORBit can be directed to the PyGTK list: http://www.daa.com.au/mailman/listinfo/pygtk Bug reports should be filed at the Gnome bug tracker: http://bugzilla.gnome.org/enter_bug.cgi?product=pyorbit James Henstridge. -- Email: james(a)daa.com.au WWW: http://www.daa.com.au/~james/

ANNOUNCE: PyGTK 2.0.0
by James Henstridge 02 Sep '03

02 Sep '03

I am pleased to announce version 2.0.0 of the Python bindings for GTK. The new release is available from ftp.gtk.org or ftp.gnome.org and its mirrors: ftp://ftp.gtk.org/pub/gtk/python/v2.0/pygtk-2.0.0.tar.gz http://ftp.gnome.org/pub/GNOME/sources/pygtk/2.0/ GTK is a toolkit for developing graphical applications that run on POSIX systems such as Linux, Windows and MacOS X (provided that the X server for MacOS X has been installed). It provides a comprehensive set of GUI widgets, can display Unicode bidi text. It links into the Gnome Accessibility Framework through the ATK library. PyGTK provides a convenient wrapper for the GTK 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 PyORBit and gnome-python, it can be used to write full featured Gnome applications. Like the GTK library itself PyGTK 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 features applications. PyGTK requires GTK >= 2.0 and Python >= 2.2 to build. Questions about PyGTK can be directed at the list: http://www.daa.com.au/mailman/listinfo/pygtk Bug reports should be filed at the Gnome bug tracker: http://bugzilla.gnome.org/enter_bug.cgi?product=pygtk James Henstridge. -- Email: james(a)daa.com.au WWW: http://www.daa.com.au/~james/

ANN: libtagedit and libtagedit-python 1.0 beta 2 released
by Torsten Marek 01 Sep '03

01 Sep '03

Hello, I am very glad to announce the release of libtagedit 1.0 beta2 and its python bindings. Libtagedit is a C++ library with Python bindings using sip (www.riverbankcomputing.co.uk) to make editing tags, information or comments in music files easy. It has a plugin infrastructure for easy extension and supports MP3 (ID3v2 reading/writing and ID3v1 reading), Ogg Vorbis and (new in this release!) FLAC files. .: Description: Due to the different structure and information stored in the several music formats, this library only supports the storage of the seven fields Title, Artist, Album, Year, Genre, Tracknumber and Comment (all of arbitrary length in every file format). Also, length and bitrate will be read from the file (more technical information like channels and sample rate may be added in future 1.x releases). Editing the tags can take place without any knowlegde of the file format on the disk, so having complete albums consisting of different formats is not a problem any more. Furthermore, using the Python bindings, file information can be easily read out or changed in scripts or interactive sessions. Creating, for example, m3u files becomes a cakewalk: --== sample code ==-- import tageditor import os m3ufile = file("files.m3u", "w") m3ufile.write("#EXTM3U\n") for f in os.listdir("."): if os.path.splitext(f)[1] not in tageditor.tagEditorExts(): continue tag = tageditor.createTagEditor(f) m3ufile.write( "#EXTINF:%i,%s - %s\n" % (tag.getLength(), tag["Artist"], tag["Title"])) m3ufile.write(tag.filename() + "\n") --== end of sample code ==-- .: Changes since 1.0b1: 2003-08-31 Torsten Marek <shlomme(a)gmx.net> * added FLAC support * changes/additions to the build system, now Ogg Vorbis and FLAC are disabled when not detected on the system * released as 1.0b2 2003-06-01 Torsten Marek <shlomme(a)gmx.net> * in id3Tag::getSongInfo(): replaced head |= tmp[0] by head |= (unsigned char)tmp[0] to avoid wrong length computation There aren't any changes in the Python bindings, they're just for completeness. .: Requirements: libtagedit: Ogg Vorbis libraries (optional) FLAC C and C++ libraries (optional) libtagedit-python: Python 2.2 or 2.3 with distutils sip 3.8 .: Where to get it: http://www.sourceforge.net/projects/libtagedit .: Where to send questions: Torsten Marek <shlomme(a)gmx.net>
