German speaking Zope users are welcome to contribute to the effort. http://www.zope.de/bibliothek/How-Tos/ http://www.zope.de * The new Zope Front Door has been installed. Comments to webmaster(a)zope.org are encouraged. http://www.zope.org * Lutz Ehrlich <Lutz.Ehrlich(a)EMBL-Heidelberg.de> has launched the German Python/Zope network. "It is meant to be a lightweight and efficient means to form a network of freelancers able to provide Python/Zope services in the German speaking part of the world." http://www.python-netzwerk.de * A mailing list has been set up to support the Zope Mozilla Initiative.

Two weeks Till Python Conference Early Bird Registration Deadline!
by Guido van Rossum 22 Dec '99

22 Dec '99

We know that the Python conference isn't until the next millennium. You have exactly two weeks left to register and qualify for the early bird registration. Since most of that time most people are taking off for the holidays, it's really NOW OR NEVER! If you haven't registered and paid by January 5, you will paying full price... So, be smart and register NOW. Also don't forget to book your hotel room by January 3. Some highlights from the conference program: - 8 tutorials on topics ranging from JPython to Fnorb; - a keynote by Open Source evangelist Eric Raymond; - another by Randy Pausch, father of the Alice Virtual Reality project; - a separate track for Zope developers and users; - live demonstrations of important Python applications; - refereed papers, and short talks on current topics; - a developers' day where the feature set of Python 2.0 is worked out. Our motto, due to Bruce Eckel, is: "Life's better without braces." Come and join us at the Key Bridge Marriott in Rosslyn (across the bridge from Georgetown), January 24-27 in 2000. Make the Python conference the first conference you attend in the new millennium! The early bird registration deadline is January 5. More info: http://www.python.org/workshops/2000-01/ The program is now complete with the titles of all presentations.

MetaKit 2.0 open source embedded database
by Jean-Claude Wippler 15 Dec '99

15 Dec '99

This announcement marks the release of MetaKit as open source. MetaKit is an efficient database library with a small footprint. It's a cross between flat-file, relational databases, and OODBMS. Keywords: structured storage, transacted commit, load on-demand, portable, C++, Python, Tcl, scripting, instant schema evolution. RELEASE NOTES: The new release is nearly identical to the recent 1.9 release, with a few minor tweaks, and updated documentation. The change is that source code is now freely available to anyone. License: X/MIT-style open source. Commercial support is provided though an Enterprise License from Equi4 Software, see the website. MetaKit 2.0 embodies the evolution of 3 years of development and production use, and is considered a pretty stable release. Both the Python and the Tcl extension interfaces have been adjusted to use the new 2.0 release number, and are now part of the core. The MetaKit home page is at: http://www.equi4.com/metakit/ with links to documentation, source code, all license details, mailing lists (moved), defect tracking (new), and a CVS repository (new). The new services are hosted on the SourceForge Open Source site. Binary builds of this library are currently available by FTP for: Unix (AIX, Digital Unix, HP-UX, Linux, Solaris), Windows (9X/NT), and Macintosh (PPC). Older release builds are available for VMS, BeOS, SGI, and a few others (all the way down to 16-bit MS-DOS). Both old and new releases remain 100% supported by yours truly. The bug database is there to report problems, and CVS is there to get fixes and patches back out to everyone - so let's use them! As the 2.0 version number indicates, this also marks the start of a new range of MetaKit releases. Having successfully proven the concepts that underpin MetaKit over the last several years, it is time to open up the system to all developers who are interested in simplicity and raw performance. Over the coming months, I'll be making a substantial number of new contributions, while at the same time inviting every interested developer to discuss ideas to make MetaKit even faster, more scalable, multi-user / -threading, and binding it to many more languages and platforms. If there is a need, separate "stable" & "bleeding-edge" areas will be set up. The website, code, and documentation are currently being adjusted to iron out all wrinkles of these changes. Hello, DBMS world :) -- Jean-Claude Wippler <jcw(a)equi4.com> <A HREF="http://www.equi4.com/metakit/">MetaKit 2.0</A> - open-source release of the powerful MetaKit 2.0 database library for flexible structured storage; features Python bindings.

Don't forget to register for the Python conference!
by Guido van Rossum 15 Dec '99

15 Dec '99

We know that the Python conference isn't until the next millennium. You still have THREE WHOLE WEEKS to register and qualify for the early bird registration. However, at least one of those weeks you will have partying and family gatherings on your mind, and when that week's over, recovery from the partying and gathering will probably take priority over registering for the conference, and as a result you might be PAYING FULL PRICE! (The horror!) That is, if your payment isn't received by January 5, 2000. So, be smart and register *before* Christmas. That's still more than ten days -- plenty of time to make travel arrangements, register for the conference, and present your boss with the bill (in that order). Our motto, due to Bruce Eckel, is: "Life's better without braces." Some highlights from the conference program: - 8 tutorials on topics ranging from JPython to Fnorb; - a keynote by Open Source evangelist Eric Raymond; - another by Randy Pausch, father of the Alice Virtual Reality project; - a separate track for Zope developers and users; - live demonstrations of important Python applications; - refereed papers, and short talks on current topics; - a developers' day where the feature set of Python 2.0 is worked out. Come and join us at the Key Bridge Marriott in Rosslyn (across the bridge from Georgetown), January 24-27 in 2000. Make the Python conference the first conference you attend in the new millennium!

Hi all, Zope 2.1.1 has been released. This is a bug-fix release that includes fixes for better handling of multiple-write conflicts, undo-related problems and problems that prevented certain third-party Zope products such as Squishdot from working. For more information, see the file CHANGES.txt in the doc directory of the distribution. As always, you can get the 2.1.1 release from Zope.org: http://www.zope.org/Products/Zope/2.1.1/ Brian Lloyd brian(a)digicool.com Software Engineer 540.371.6909 Digital Creations http://www.digicool.com <A HREF="http://www.zope.org/">Zope 2.1.1</A> - a free, open source web application platform used for building high-performance, dynamic web sites; bug-fix update.

pxDislin - release 0.1
by Paul M 14 Dec '99

14 Dec '99

DESCRIPTION: ----------- pxDislin is an object-oriented wrapper around the DISLIN plotting library. DISLIN is a powerful and flexible multiplatform (Win32, Unix, Linux, etc.) library designed for displaying scientific data. DISLIN's author, Helmut Michels, has made available a DISLIN plotting extension for the Python programming language (see http://www.linmpi.mpg.de/dislin/ for more details). pxDislin provides a set of classes which represent various aspects of DISLIN plots, as well as providing some easy to use classes for creating commonly used plot formats (e.g. scatter plots, histograms, 3-D surface plots). A major goal in designing the library was to facilitate interactive data exploration and plot creation. Documentation and a demo program are included. The library has been tested on WinNT and FreeBSD, but I anticipate that it should work on any platform which can make use of Python, NumPy, and the DISLIN python extensions. Feedback, comments, and critique are gladly accepted (email: paul.magwene(a)yale.edu). VERSION: ------- This is release 0.1 of pxDislin. URL: ---- You can find pxDislin at: http://pantheon.yale.edu/~pmm34/pxdislin.html Paul Magwene paul.magwene(a)yale.edu <A HREF="http://pantheon.yale.edu/~pmm34/pxdislin.html">pxDislin 0.1</A> - a set of object-oriented classes which work with the DISLIN Python extension (for displaying scientific data).
