Nov. 11, 1999

Hi, I'm pleased to announce the first release of GPS - Groves and Property Sets for Python. Suggestions and bug reports should be sent to: grove(a)infotek.no Geir O. Grønmo -------------------------------------------------------------------------- Title: GPS - Groves and Property Sets for Python Version: 0.10 Released: November 10th 1999 Author: Geir O. Grønmo, grove(a)infotek.no License: GPL Homepage: http://www.infotek.no/~grove/software/gps/index.html - -- >>> What is GPS? GPS is an implementation of the groves and property set concepts defined in the HyTime and DSSSL standards. GPS is written in Python, and should work* on any platform to which Python have been ported - including the Java Platform. There are two implementations in the current distribution, one in-memory implemention and one that supports ZODB - the Zope Object Database. Both groves, property sets and grove plans can be made persistent by the ZODB implementation. - -- >>> Features o Loading of property sets from documents conforming to the Property Set DTD, or any derived DTD [requires architectural processing]. o Grove plans. Default grove plans is automatically created by wrapping a GrovePlan object around a property set. Inclusion and omitting of modules, classes and properties are fully supported. o Two grove node implementations, both generic classes for representing grove nodes. o ZODB - Zope Object Database versions of all grove, property set and grove plan classes. o Module for building XML groves from SAX event streams. This module also contains a class for emitting SAX events by walking XML groves. o Sample Property Sets - -- >>> Requirements - Python 1.5.2 or newer [3] - An SGML/XML parser with a SAX driver - SAX for Python [4] - xmlarch 0.25, optional unless architectural processing is needed [5] - -- >>> References [1] http://www.jpython.org/ [2] http://www.ornl.gov/sgml/SC34/ [3] http://www.python.org/ [4] http://www.stud.ifi.uio.no/~larsga/download/python/xml/saxlib.html [5] http://www.infotek.no/~grove/software/xmlarch/index.html [6] http://www.infotek.no/~grove/software/gps/licence.html * The ZODB implementation won't work in a Java environment, since the ZODB contains code written in C. -------------------------------------------------------------------------- <A HREF="http://www.infotek.no/~grove/software/gps/">GPS 0.10</A> - Groves and Property Sets for Python; an implementation of the groves and property set concepts defined in the HyTime and DSSSL standards.

Molecular Modelling Toolkit 2.0
by Konrad Hinsen Nov. 9, 1999

Nov. 9, 1999

Announcement: Version 2 of the Molecular Modeling Toolkit ========================================================= The Molecular Modelling Toolkit (MMTK) is an Open Source library for molecular simulation applications, written in Python with some C extension modules. In addition to providing ready-to-use implementations of standard algorithms, MMTK serves as a code basis that can be easily extended and modified to deal with standard and non-standard problems in molecular simulations. Version 2 contains many new features and enhancements compared to the previous version 1.2 The most important ones are - Ewald summation - new algorithm for nonbonded list generation (faster and uses less memory) - thermostat, barostat, and distance constraints (SHAKE) for MD - support for nucleotide chains (DNA, RNA) - deformation force field for normal mode calculations on big proteins - much extended manual Note that version 2 is not compatible with earlier releases, because it makes use of the package structure introduced with Python 1.5. All import statements must therefore be modified. For compatibility reasons, MMTK 1.2 will remain available in parallel with MMTK 2.0. For more information and for downloading, see the MMTK Web site at http://starship.python.net/crew/hinsen/MMTK/ or http://dirac.cnrs-orleans.fr/MMTK/ ------------------------------------------------------------------------------- Konrad Hinsen | E-Mail: hinsen(a)cnrs-orleans.fr Centre de Biophysique Moleculaire (CNRS) | Tel.: +33-2.38.25.55.69 Rue Charles Sadron | Fax: +33-2.38.63.15.17 45071 Orleans Cedex 2 | Deutsch/Esperanto/English/ France | Nederlands/Francais ------------------------------------------------------------------------------- <A HREF="http://starship.python.net/crew/hinsen/MMTK/">MMTK 2.0</A> - the Molecular Modelling Toolkit, an Open Source library for molecular simulation applications, written in Python with some C extension modules.

PSI-0.02 - Persistent Multithreaded CGI for Apache
by henk_p＠my-deja.com Nov. 9, 1999

Nov. 9, 1999

Hi, This the second release of PSI, or the Python Script Interface, A second attempt by me at persistent cgi scripting in python. With PSI, cgi-scripts are run by a shared python interpreter living outside of the webserver process. Like PCGI, a small 'wrapper' program is used to connect any CGI capable webserver to the shared interpreter. PSI is multithreaded, every CGI request runs in a seperate thread. PSI provides as much of the Stanard CGI environment (sys.stdin, sys.stdout, os.environ) as possible. And by doing so should be compatible with existing CGI scripts written in python. You can download PSI0.02 at: http://huizen.dds.nl/~d50/psi0.02.tgz suggestions and or questions about PSI?, mailto: csg6031(a)wing.rug.nl <A HREF="http://huizen.dds.nl/~d50/psi0.02.tgz">PSI 0.02 (click to download as .tar.gz file)</A> - Python Script Interface; an Apache module for long-running Python CGI scripts, similar to FastCGI.

Mailman 1.1 - The GNU Mailing List Manager
by Barry A. Warsaw Nov. 6, 1999

Nov. 6, 1999

I have just uploaded Mailman version 1.1 to www.list.org, and this will hopefully soon be mirrored to ftp.gnu.org. This release is precipitated by the removal of all GIFs from the distribution. There have also been some performance improvements, although lots more can still be done. ;) See the NEWS file excerpt below for details of changes. Sadly, the internationalization effort has not yet been integrated (mostly due to time constraints of the core maintainers). Mailman, the GNU mailing list manager, is software to help manage email discussion lists, much like Majordomo and Smartmail. Unlike most similar products, Mailman gives each mailing list a web page, and allows users to subscribe, unsubscribe, etc. over the web. Even the list manager can administer his or her list entirely from the web. Mailman also integrates most things people want to do with mailing lists, including archiving, mail-to-news gateways, and so on. Mailman is writtein primarily in Python, with a little bit of C for security. See http://www.list.org or http://www.gnu.org/software/mailman/mailman.html for details and downloading. -Barry -------------------- snip snip -------------------- - All GIFs removed. See http://www.gnu.org/philosophy/gif.html for the reason why. - Improvements to the Pipermail archiver which make things faster. Primary change is that the .txt files are not gzip'd on every posted message. Instead, use the new cron script `nightly_gzip' to gzip the .txt file in batches (this means that the .txt file will lag behind the on-line archives a little). - From the C drivers programs, Python is invoked with the -S option. This tells Python to avoid importing the site module, which can improve start up time of the Python process considerably. Note that the command line script invocation has not been changed. - New configuration variables PUBLIC_EXTERNAL_ARCHIVER and PRIVATE_EXTERNAL_ARCHIVER which can contain a shell command string for os.popen(). This can be used to invoke an external archiver instead of the bundled Pipermail archiver. See Defaults.py for details. - new script `bin/find_member' which can be used to search for a member by regular expression. - More child processes are reaped, which should eliminate most occurances of zombie processes. - A few small miscellaneous bug fixes (including PR#99, PR#107) and improvements to the file locking algorithms. -------------------- snip snip -------------------- <A HREF="http://www.list.org/">Mailman 1.1</A> - The GNU Mailing List Manager, implemented primarily in Python; changes: no more GIFs (due to LZW patent issues), improvements to bundled Pipermail archiver, miscellaneous bug fixes.

New general purpose "sparse matrix" package - v0.1
by Travis Oliphant Nov. 5, 1999

Nov. 5, 1999

I've finally released Version 0.1 of a general purpose Sparse matrix package. It is available at http://oliphant.netpedia.net/packages/SparsePy.tgz RPMS for Linux may be available soon. The package requires a FORTRAN compiler, a C compiler, and a copy of the BLAS for your system. Currently the makefiles only work for a UNIX system using gcc and g77, they can be modified to work for any compiler. Features: * Initialization of Sparse Matrices using diagonal or coordinate convention. * Matrix-vector multiplies * Matrix-Matrix add, subtract, multiply, conjugate, transpose * Direct inversion of Sparse Linear Systems. The first three features are due Yousef Saad's SPARSEKIT2 package while the last feature is due to SuperLU by Demmel, Gilbert, and Li. The implementation is a Python class which has methods that call on wrapped versions of these libraries. There are other Sparse Matrix implementations available but this one is trying to be general purpose. Any suggestions and improvements are appreciated. Travis Oliphant Oliphant.Travis(a)altavista.net <A HREF="http://oliphant.netpedia.net/packages/">SparsePy 0.1</A> - first release of a general-purpose sparse matrix calculation package for Python; requires FORTRAN to compile.

Nov. 5, 1999

[Moderator's note: "IPC8" is the "8th Internatinal Python Conference", organized by the "Python Software Activity" (PSA), taking place 24-27 January 2000 in Alexandria, VA, USA.] IPC8 Call For Demos and Posters Important Dates * Nov. 30 : Deadline for demos and posters. * Dec. 15 : Notification of acceptance for demos and posters. Demonstrations and Posters We invite researchers and developers to present their work in demonstrations or posters. Works in progress and results which don't warrant a full paper may be presented this way, as well as demonstrations of interesting applications. Demos and posters will be selected based on the broad applicability of new technologies and novelty of new approaches. Tables and power will be provided. Computers will not be provided; if you intend to do a demonstration, bring your own with all the software you need. There may be a slow Internet connection (at most a shared ISDN line); please let us know if Internet access is important to your demonstration. What is a poster? When presenting a poster, you typically bring one or more posters that can be tacked up to a wall. The posters should provide a concise summary of your work, and diagrams or other graphics are strongly encouraged. You then stand next to your poster and discuss your work with other conference attendees (who will undoubtedly ask why you're standing there). If you're feeling confident, you can provide handouts that explain your research or project in more detail, or tell where to find more information. Bring plenty of copies. So, what's a demo? A demo is a poster, but you use your computer to actually show people what you did. You can have a slide presentation or let people play with your applications. If you want to give a demonstration, be sure to bring your computer! What to Submit and How to Submit It To request space for a demonstration or poster, send an email to Fred Drake (fdrake(a)acm.org) describing your demonstration or poster. If you have special space or power requirements, please be sure to include the appropriate information. If you require Internet connectivity, be sure to tell us about that as well! For more information Questions regarding demo and poster submissions should be addressed to Fred Drake (fdrake(a)acm.org). -- ----------- comp.lang.python.announce (moderated) ---------- Article Submission Address: python-announce(a)python.org Python Language Home Page: http://www.python.org/ Python Quick Help Index: http://www.python.org/Help.html ------------------------------------------------------------
