Sybase module 0.33pre2 released
by Dave Cole 09 Feb '02

09 Feb '02

What is it: The Sybase module provides a Python interface to the Sybase relational database system. It supports all of the Python Database API, version 2.0 with extensions. WARNING: Since the last release I have come to the realisation that the Sybase dynamic SQL functionality is not nearly general enough to use for correct DB-API functionality. I have thrown up my hands and gone back to the drawing board with the high level Sybase.py module. Once the module is stable again there will be three differences between the new and old functionality: 1) The paramstyle is now 'format'. This means that where you previously did something like this: c.execute("select * from titles where title like ?", ['The %']) you now have to do this: c.execute("select * from titles where title like '%s'", ['The %']) or this: c.execute("select * from titles where title like 'The %'") 2) Since the cursors are no longer using dynamic SQL there will no longer be an extra result set which reported the status of the temporary stored procedure. This should remove some of the confusion behaviour of cursors. There should be fewer restrictions on the use of cursors. 3) Threading is enabled in the CT library wrapper by default. PLEADING: Please download the pre-release version, try it out, and then send me some mail telling me what you found. You would be surprised at how little mail I get regarding the Sybase module, I really do need your help. The module is available here: http://www.object-craft.com.au/projects/sybase/sybase-0.33pre2.tar.gz The module home page is here: http://www.object-craft.com.au/projects/sybase/ - Dave -- http://www.object-craft.com.au

RELEASED - StandaloneZODB 1.0 final
by barry＠zope.com 08 Feb '02

08 Feb '02

I'm please to announce the release of StandaloneZODB, the Python object persistency system also known as the Z Object Database. ZODB is the object-oriented database underlying Zope; the StandaloneZODB project's goal is to provide those same facilities to non-Zope related Python applications. Today we are releasing StandaloneZODB 1.0 final. A brief description of the changes since release candidate 1 is outlined below. StandaloneZODB is based on the same code as the ZODB in Zope, albeit on a separate release branch. Its inspiration comes from Andrew Kuchling's StandaloneZODB project on SourceForge. While there are still some differences, the Standalone 1.0 release is the first on the path toward convergence. Subsequent releases should complete the merge of Andrew's and Zope Corporation's packages. The StandaloneZODB release includes the following components: - Core ZODB, including the persistence machinery - Standard storages such as FileStorage - Supporting modules such as ExtensionClass - The persistent BTrees modules - ZEO - Experimental Berkeley storages - Some documentation <wink> See the README file for details on building and installing StandaloneZODB. For details on using ZODB, see Andrew's included user guide. StandaloneZODB 1.0 is released under the ZPL 2.0. It should be compatible with all Python versions from Python 2.1 to Python 2.2. It may or may not work with versions earlier than Python 2.1. Download StandaloneZODB-1.0 from: http://www.zope.org/Products/StandaloneZODB and visit the StandaloneZODB Wiki page at: http://www.zope.org/Wikis/ZODB/StandaloneZODB See also: http://www.zope.org/Wikis/ZODB/FrontPage for more information about our long-range ZODB plans. Enjoy, -Barry Barry A. Warsaw Zope Corporation, Pythonlabs barry(a)zope.com -------------------- snip snip -------------------- What's new in StandaloneZODB 1.0 final? Release date: 08-Feb-2002 ======================================= All copyright notices have been updated to reflect the fact that the ZPL 2.0 covers this release. Added a cleanroom PersistentList.py implementation, which multiply inherits from UserDict and Persistent. Some improvements in setup.py and test.py for sites that don't have the Berkeley libraries installed. A new program, zeoup.py was added which simply verifies that a ZEO server is reachable. Also, a new program zeopack.py was added which connects to a ZEO server and packs it.

Slides on the web
by Guido van Rossum 07 Feb '02

07 Feb '02

I've put some new sets of powerpoint slides on the web, at http://www.python.org/doc/essays/ppt/ Scrolling to the end, you'll find: OSCON 2001 Keynote The slides I used for my keynote-in-absentia at the Open Source Convention 2001, in San Diego, CA. Introduction to Python A 3 hour introductory tutorial that I gave at LinuxWorld in New York City, January 2002. It covers Python 2.2 (but mostly sticks to timeless features). What's New in Python 2.2 What the title says; a talk that I gave at LinuxWorld in New York City, January 2002, and earlier at a Washington, DC ZPUG meeting. Python 10 DevDay Keynote The slides I used for my Developers Day keynote at the Python10 Conference, February 2002 in Alexandria, VA. Note: I've given up making HTML. There are plenty of open source tools that can read PowerPoint files now, and the HTML that PowerPoint generates gets worse with each version it seems. :-( --Guido van Rossum (home page: http://www.python.org/~guido/)

[ANN] Frowns Chemoinformatics system
by Brian Kelley 07 Feb '02

07 Feb '02

Frowns is a chemoinformatics system written almost entirely in python. This software reimplements some of the functionality of the Daylight toolkits but it is not meant as a replacement. Daylight's code has higher performance, commercial support, more users, more complete testing, documentation, industry backing, and a cool set of people working for them. Plus, you can run PyDaylight located at http://www.dalkescientific.com/PyDaylight/ if you don't like the C API. Given that, you may want to use FROWNS if you; * are interested in the implementation details of chemical information software * want to teach same * have ideas that can't be implemented in the Daylight toolkit (new types of ring or aromaticity perception, support for different operating systems and platforms, etc.) * don't have the financial resources for the Daylight tools * just plain can't stand the idea of non-free software * have nothing better to do in your free time. Frowns currently includes the following features * Smiles parser * Smarts substructure searching (using the bindings to VFLIB) * SD file parser with SD field manipulations * Depiction for SD files with coordinates * Molecule Fingerprint generation * Several forms of Ring Detection available * Simple aromaticity perception * Full source code You can download the latest version of frowns at http://staffa.wi.mit.edu/people/kelley/ Or you can just skim the tutorial at http://staffa.wi.mit.edu/people/kelley/frowns.html Brian Kelley bkelley(a)wi.mit.edu Whitehead Institute for Biomedical Research

Pypar 1.0 - Simple and efficient MPI binding for Python
by ole＠cuttlefish.anu.edu.au 07 Feb '02

07 Feb '02

PyPAR 1.0 - Simple and efficient MPI binding for Python Copyright (C) 2001, 2002 Ole M. Nielsen ------------------------------------------------------- This is to announce GPL publication of pypar, ver 1.0 - a simple and efficient Python binding to MPI for parallel programming using Python. Background: ----------- The use of multi processor computers is becoming increasingly common and they appear in many forms: Desktop computers with more than one processor sharing memory, clusters of PC's connected with fast networks known as Beowulff clusters, and high-end super computers all make use of parallelism. To efficiently use these machines in a portable way one must be able to control communication among programs running in parallel. One such standard is the Message Passing Interface (MPI) for inter-processor communication. Python and MPI: --------------- There are a number of other Python bindings to MPI that are more comprehensive than pypar (PyMPI, Scientific Python). However, pypar stands out by not requiring the Python interpreter to be modified, by being very easy to install and by by shielding the user from many details involving data types and MPI parameters without sacrificing the full bandwidth provided by the underlying MPI implementation. Download: --------- Pypar can be downloaded from http://datamining.anu.edu.au/pypar where there is also more information available. Credentials: ------------ Pypar was developed by Ole Nielsen at the Australian National University in 2001 for use in the APAC Data Mining Expertise Program and has been published under the GNU Public License (http://www.gnu.org/licenses/gpl.txt) as a small contribution Contact: Ole.Nielsen(a)anu.edu.au <P><A HREF="http://datamining.anu.edu.au/pypar">Pypar 1.0</A> - A simple and efficient MPI binding for Python.

RELEASED: Anygui 0.1 (final)
by mlh＠vier.idi.ntnu.no 05 Feb '02

05 Feb '02

Greetings! Anygui 0.1 has been released, and may be dowloaded from the anygui project page (http://sourceforge.net/projects/anygui). Anygui is a generic GUI package which allows you to write programs that will work with several backends, such as Tkinter, wxPython, PythonWin and Java Swing. The name is inspired by the standard library package anydbm, because the behaviour is similar: You write your program using the Anygui API, and Anygui figures out which back-end to use. For more information, please visit the Anygui web site at http://www.anygui.org Magnus Lie Hetland, Anygui admin -- Magnus Lie Hetland The Anygui Project http://hetland.org http://anygui.org

PySomorph 0.92 Graph Isomorphism Package Released
by Brian Kelley 05 Feb '02

05 Feb '02

PySomorph is a python package for investingating subgraph isomorphism. Subgraph Isomorphism is useful for a number of pratical applications spanning from relational theory to investigating chemical structures. PySomorph is a binding to the University of Napoli's <http://amalfi.dis.unina.it/graph/> graph isomorphism library. The main benefit is that edges and nodes of graph structures can be arbitrary python objects. This allows for an amazing amount of flexibility in the creation and searching of various graphs. * Uses disutils for unix/linux installations. * added an example application, NetWorkGraph. This ia a subgraph isomorphism application that searches network topologies.
