    Zope Weekly News is a digest of some of the useful and interesting
    events which have occurred on the various Zope mailing lists and the
    Zope.org site.  It is published each Wednesday evening.

    Any opinions contained in the Zope Weekly News are those of the
    chronicler exclusively.

    Suggestions for ZWN items are happily accepted.  Please mail them
    to <mike@digicool.com>, put 'ZWN' somewhere in the subject and
    remember to include URLs.


  * Zope 2.1.4 has been released.  The blame goes to Evan Simpson, who
    pointed out a problem which would allow people to construct links
    to a Zope server such that it would cause JScript (or other
    HTML-embeddable scripts) to be executed in the user's browser.
    This script would appear to come from the Zope server.  While this
    is not too terribly dangerous (your browser doesn't have any
    security holes, right?), all users are encouraged to upgrade.


New Releases

  * "brianh" has been given custodianship of the Ultraseek DA product.
    This is a Zope Database Adapter which provides an interface to
    Infoseek's Ultraseek Server search engine.


  * "ngarcia" announced the first public release of the Wampum
    Generator, a CyberCash Connector for Zope.  This product gives
    application developers the ability to process Internet credit card
    transactions in Zope.



  * Digital Creations has released an updated version of the Sybase
    Database Adapter.  It's hoped that this release fixes the memory
    leaks of the prior version.


  * "Drew" has updated the ZPhotoAlbum product.  This product presents
    pages of ZPhotos (images) scaled to the user-specified thumbnail
    size.  The present version is 0.4.3.


  * Jonothan Farr <jfarr@real.com> updated his LocalFS product.  This
    product allows Zope to serve files out of (shockingly enough) the
    local filesystem.  Additionally, it can serve from network shares
    if you are running Zope on a Windows machine.


Zope.org items

  * Chris McDonough <chrism@digicool.com> has crafted a gentle and
    easily digested introduction to Zope he's called, "Gain Zope
    Enlightenment By Grokking Object Orientation".  If you are _not_ a
    computer scientist, geek or Python programmer, this seems to be
    the place for you to start.  He does a wonderful job of answering
    a very difficult question, "What is Zope?"  At the end, the
    complete novice should have a decent understanding of how Zope
    works, what an object is and what it means to publish one, and how
    these objects work.


  * "muesli" created a HowTo which explains the 'domains' security
    feature of user objects.  This allows you to restrict access to
    specific hosts, domains, or IP addresses.


  * "jec" posted a HowTo which explains automating the starting and
    stopping (at startup and shutdown) of a Zope server on a Red Hat


  * "vernier" has written a HowTo on creating custom Zope Debian packages.


  * "lalo" wrote a HowTo which describes how to use cron to trigger
    events on a Zope server.


  * Jens Vagelpohl <jens@digicool.com> has distilled the essence of
    his experience creating the Zope Demo CD which was distributed at
    IPC8 and created a HowTo so you can create one, too.  These CDs
    work on both Windows and Linux systems.  On a Windows system, the
    Zope server can start right off the CD, and a web browser can
    automatically be launched to view the server's content.  All this
    without writing a single byte to the user's hard drive.


  * Chris Petrilli <pertilli@digicool.com> posted a proposal titled "A
    Confidence Mechanism in User Role Management".  The idea is to
    make Zope Authentication more flexible than all-or-nothing.  There
    is a discussion about this proposal in the Zope-PTK mailing list.



  * Last week, the editor-in-chief of O'Reilly was mistakenly called
    "Frank Wilson".  His name is in fact Frank Willison.
