Initial Releases of MatLabDA, Latex- and Graph Method
by Stephan Richter 23 Sep '01

23 Sep '01

Hello everyone, Due to the intensive work on zQuest, I was able to finish a lot of work. Since some of the development for zQuest can be split into several small Products, I decided to take today off and do that. So three products were born: ** MatLab DA and Method ** This product allows you to "connect" to the MatLab Kernel and then execute mathematical expressions (in MatLab syntax). Each statement is separated by a new line. Some of the nicer features are actually in the MatLab Connection component. It keeps a pool (size is specified by user) of connections to the MatLab Kernel. When a query is executed the used connection is locked (and afterwards released) to provide a maximally optimized response time. Originally Zope and PyMat (The module used to connect to MatLab) did not like each other, since Zope would regularly reload modules causing the PyMat module to produce a segmentation fault. Thanks to Jason Orendorff's "DestructionListener" idea I was able to catch the reload occurrences and handle them gracefully. URL: http://demo.iuveno-net.de/iuveno/Products/MatLabDA ** Latex Method ** Using the Latex Method one can compile math-mode Latex code into an image that is displayed. The LatexMethod uses the Image class as base, so that the same API applies. The Latex Method is very flexible and supports the AMS (American Mathematical Society) Latex Extensions. It might seem that there are many requirements associated with this product, but I developed on a standard RedHat Linux machine and I had no problems. All tools (Latex, Ghostview, small conversion tools) were all there by default. URL: http://demo.iuveno-net.de/iuveno/Products/LatexMethod ** Graph Method ** The Graph Method is similar to the Latex Method in the sense that it creates an image from a given piece of code. In fact, the object provides a nice graphing environment based on PIL (Python Imaging Library). On top of PIL there are several other features. For educational purposes it is often nice to have "moving pictures", so I added Animation support to allow animated GIFs (using GIFSicle, which you will need to install). Furthermore there are a couple of very useful components that can be used to quickly generate nice results: Arrow, Vector, Grid, Axis, Coordinate System, Data Point, Function Curve and Random Data Curve. A complete API reference can be found in the Appendix of the zQuest Users manual, which can be downloaded from http://demo.iuveno-net.de/iuveno/Products/ZQuest/Documentation. URL: http://demo.iuveno-net.de/iuveno/Products/LatexMethod I hope that you will find one or the other product useful and will try it. Since they all have outside dependencies, I would like to hear about your experiences. As always, I am thankful to any comments, suggestions and criticism.

ATTENTION: Zope.org migration issues
by Martijn Pieters 21 Sep '01

21 Sep '01

Hello to all Members of Zope.org, As some of you may know, we are hard at work building a new Zope.Org website based entirely on the CMF. Because this is going to be a completely new server, content on the current server has to be migrated and converted for the new site. Most of the content on Zope.org can be migrated quite easily. However, there are a few content types in use on Zope.org that cannot or will not be migrated directly or at all. These types will have to be converted to another content type if they are to be migrated to the new site. You only have to worry about content in your own Member Folder, and only if you really want it migrated. Here are the problem types and what to do with the content they represent: - DTML Method: paste the contents into a 'STX Document' for structured text, or 'Formatted Document' for html formatting. DTML scripting will no longer be supperted on the new Zope.org site. - XML Document: XML Document is usually used to act as the source for a end-document. Render the end-document view to HTML and paste the result into a Formatted Document - ZTopic: Unfortunately, there is no alternative for migrating a ZTopic. If you have created a ZTopic in your Member Folder and feel that it provides value to Zope.org visitors let me know and I'll see if we can provide an alternative. -- Martijn Pieters | Software Engineer mailto:mj@zope.com | Zope Corporation http://www.zope.com/ | Creators of Zope http://www.zope.org/ ---------------------------------------------

Zope Controller GUI 1.1.2 (Mac OS X) released with source
by Richard Jones 21 Sep '01

21 Sep '01

Bizar Software is pleased to make available a new release of their Zope Controller GUI for Mac OS X. This release really removes the start script, adds file selection dialogs and fixes some race conditions in startup/shutdown. The binary now uses the standard OS X installer. This is also hopefully the last "development" release of the controller. The Mac OS X Zope Controller is a Graphical User Interface for Mac OS X which allows user-friendly control of a Zope server on the local machine. This is a modified version of the controller we will ship with the next version of our Bizar Shop software product. The modification involves the removal of some Shop-specific code that simply doesn't apply to Zope. Screenshots are available at Bizar Software's website.

ZBabel 2.0.0 beta 1 released
by Stephan Richter 20 Sep '01

20 Sep '01

Hello everyone, I am very pleased to announce The Zope Babel Translation System 2.0.0 beta 1. It has been a while that I made a release, but I finally got around it and made some of the annoying bug fixes. URL: http://www.zope.org/Members/srichter/Products/ZBabel (my Zope Site) URL: http://demo.iuveno-net.de/iuveno/Products/ZBabel (iuveno's Demo Site) Some of the new "features" in this release include: - Made ZBabel Zope 2.4 & Python 2.1 compatible by replacing regex with re and fixing a bug in the tag code. - Finally added support, so that an attribute in any tag of the kind name='value' is interpreted as name having a string (and not an expression) as value. - Made the 'SQL Methods' and 'Init Tables/Views' Zope GUI 2.3+ compatible. - Added a management screen (not available over a tab) that allows to edit long phrases by providing textareas. You can get to this screen by clicking on the label of the phrase. When you press "Edit", then you will be brought back to the regular translation screen. Please feel free to send me any comments and criticism to srichter(a)cbu.edu.

Zope Controller GUI 1.1.1 (Mac OS X) released with source
by Richard Jones 18 Sep '01

18 Sep '01

Bizar Software is pleased to make available a new release of their Zope Controller GUI for Mac OS X. This release should be considered a development release - it's only been tested very lightly. This release includes the source and removes the external start script. Yay on both counts! The Zope Controller is a Graphical User Interface for Mac OS X which allows user-friendly control of a Zope server on the local machine. This is a modified version of the GUI controller we will ship with the next version of our Bizar Shop software product. The modification involves the removal of some Shop-specific code that simply doesn't apply to Zope. Currently, only the Mac OS X version is available. Windows Real Soon (next week, we hope).

Zope Controller GUI 1.1.0 (Mac OS X) released
by Richard Jones 17 Sep '01

17 Sep '01

Bizar Software is pleased to make available a first release of their Zope Controller GUI for Mac OS X. This release should be considered a development release - it's only been tested very lightly. This is a modified version of the GUI controller we will ship with the next version of our Bizar Shop software product. The modification involves the removal of some Shop-specific code that simply doesn't apply to Zope. Currently, only the Mac OS X version is available, and unfortunately only in binary form. Potential users *must* read the license (hey, it's really short) and the installation instructions! The code will be released under an open-source license (very much like the binary release license) just as soon as I figure how to do that sanely. Definitely will be coming though!

by Andrew Kenneth Milton 17 Sep '01

17 Sep '01

I have brought exUserFolder up to 2.4.x compatibility, exUserFolder is now at 0.6.0, the current release is considered stable. It also now uses fcrypt (included) when crypt can't be found on your system, for the default encryption of passwords. Some annoying little bugs were ironed out. A basic API Doc explaining what you need to do to create your own Auth and Property Sources is included. Alex Verstraeten contributed zodbAuthSource to the core list of Auth Sources available.

ZStyleSheet demonstration
by Adrian Hungate 16 Sep '01

16 Sep '01

There is now a very simple demonstration of ZStyleSheet in use available for downloading. It is packaged as a ZEXP file, which should be imported into a normal folder (It is NOT a product). The file is available from http://www.zope.org/Members/haqa/ZStyleSheet along with the latest version, which is required to run the demo. I hope this helps users a little, I will be continuing expanding this demo as I further develop ZStyleSheet. Adrian... -- Adrian Hungate Try Zope - http://www.zope.org - You might like it.
