I just posted an anouncement for a modul template I submitted. I checked the posting now and noticed that the email was wrong. its sparhawk(a)aon.at and not sparhaw-(a)aon.at. I don't know how this happend, because I'm pretty sure that I typed it right and I experienced the same problem with another post as well. Strange. -- Bye, Gerhard In Windows, the graphic driver is responsible for maintaining the mouse. :))) Need a daily tv guide? Look at my homepage: http://members.aon.at/sparhawk

[ANC] Template.py
by Gerhard Gruber 29 Feb '00

29 Feb '00

I've just submitted a module template.py to the source tree at http://www.vex.net/parnassus/resource.py. This module was primarily written for handling templates of HTML files in CGI scripts but can be used in any kind of programm that needs to use pre-prepared textfiles with variable content. Check out the description I entered for more details. You can download it at http://members.aon.at/sparhawk in the download section and you can email me at sparhawk(a)aon.at if you have question concerning the use or bug reports. I don't expect problems, though, because it is fairly easy to use. :) -- Bye, Gerhard In Windows, the graphic driver is responsible for maintaining the mouse. :))) Need a daily tv guide?

Temporary mail problems to python.org
by webmaster＠python.org 25 Feb '00

25 Feb '00

Some of you may have experienced temporary problems sending mail to the python.org domain. As of about noon EST, Monday 21-Feb-2000, these problems should have been resolved, and your queued up messages should be getting delivered to email addresses @python.org. In brief, we are in the process of moving most python.org services to a faster machine. Friday afternoon (in direct and willful violation of Warsaw's Second Law[1]), we changed the MX record for python.org to point to dinsdale.python.org. Most email was already being handled by this machine, but via a clunky forwarding scheme through the old machine. Unfortunately, due to a misconfiguration of CNRI's gateway, traffic to the smtp port of dinsdale was being blocked. This should now be fixed, and queued mail should be flowing again; no mail should have actually been lost. If you experience any residual problems please let us know (you can email me directly at my CNRI address, which was unaffected). -Barry [1] http://www.python.org/~bwarsaw/software/laws.html -- ----------- 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 ------------------------------------------------------------

Zope Weekly News - Wed, 16 Feb 2000
by Mike Pelletier 25 Feb '00

25 Feb '00

G'day, 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. Announcements * Lalo Martins has begun writing a Zope tutorial in Brazilian Portuguese. His announcement stated he was halfway through, and that it was already useful. http://zope.gf.com.br/ZopeIntro New Products * Software Product: "Local Factory Objects", submitted by "lalo" This package appears to allow you to create Factory objects (objects which manage the creation of ZClass instances) in places other than a Software Product. This is useful to prevent the 'Add' list from becoming unwieldy by placing the Factories in the relevant portions of the site, rather than making them globally available. http://www.zope.org/Members/lalo/LocalFactory/LocalFactory-0.1.tar.gz * Software Product: "Persistent List and Dictionary", submitted by "AndrewWilcox" Like the PersistentMapping object, PersistentList and PersistentDict are classes that look like the basic Python types of the same names, but which are persistent and which alert the ZODB when their contents have changed. PersistentDict differs from PersistentMapping in two respects-- It is not limited to strings as keys, and it does not hide keys that begin with an underscore. http://www.zope.org/Members/AndrewWilcox/PersistentListDict * Software Product: "ZDP Tools 0.1", submitted by "roeder" This is a distribution of the very tools that make the Zope Documentation Project work. Follow the second link below to see the ZDP in action for an idea of what is possible with this toolkit. http://www.zope.org/Members/roeder http://zdp.zope.org:8080/ZDP * Software Product: "StructuredText Document", submitted by "tseaver" This is a very simple, ZClass based Product which provides a means of displaying structured text documents without creating a second DTML Method to wrap the structured text. This is often very handy. Note that ZClasses cannot be used as a Folder's index_html. http://www.zope.org/Members/tseaver/STX_Document Updates * Software Product: "load_site.py with additional features", submitted by "itmar" This is a modification of the load_site utility that comes with Zope. This utility sucks files and directories out of a local filesystem and creates corresponding Zope objects with their contents. Itmar has made some useful changes: the DTML it generates is now in the new Zope 2 syntax; certain HTML metadata and display options may be placed in object properties; javascript can be stripped out of headers (for making Dreamweaver output more lightweight); can clean up output of certain Microsoft products so that quotes display properly on other platforms. http://www.zope.org/Members/itmar/load_site * Software Product: "ZWiki 0.4", submitted by "simon" ZWiki is a product which allows the creation of wiki webs in Zope. What is a wiki web? Well, I'm not sure, but Peter Merel says that the typical wiki web is "insecure, indescriminate, user-hostile, slow, and full of difficult, nit-picking people." And these are the GOOD points! Seriously, a Wiki Web appears to be a dynamic web site which is built, torn down and rebuilt by anonymous users. 0.4 adds a number of tweaks, tunings, and new default content. See the link for details. "simon"'s news item does not include a link to the Product, so it's included below as a second link. http://www.zope.org/Members/simon/ZWiki/ZWiki_0.4_released http://www.zope.org/Members/simon/ZWiki Zope.org items * How-To: "Build a WAP site with Zope", submitted by "Duncan" This HowTo describes what you would need to do to allow Zope to serve WML pages to cell phones, PDAs, and other wireless devices via WAP. It addresses issues such as setting the content type correctly, caching, serving bitmaps, and making the standard Zope html-include files both WML and HTML-friendly. http://www.zope.org/Members/Duncan/wap_howto * "Zope Docs", submitted by "AlexR" This is a pretty handy resource. "AlexR" has compiled all the HowTo documents on Zope.org and made them available as a printer-friendly Adobe PDF file. In addition, this page has links to a pair of printer-friendly lists of all the HowTo documents on Zope.org, one sorted by name, and one by date. http://www.zope.org/Members/AlexR/ZopeDocs * How-To: "add users in python", submitted by "element" In addition to describing the process for adding users to a Zope server from a Python Product, this brief How-To also describes adding the actual User Folder ('acl_users'), adding a local role, and assigning a role to a user. http://www.zope.org/Members/element/addingUsersInPython * How-to: "Generate URLs for Objects", submitted by "jim" This is a very thorough How-To on a common, but simple (once you know the trick) problem. Astonishingly, Jim manages to stretch a one-line answer into a two-page document. I don't want to spoil the surprise ending, but it is possible to ask an object for it's canonical URL, and this How-To explains how. http://www.zope.org/Members/jim/ObjectURLs == Mike Pelletier. mike(a)digicool.com -- ----------- 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 ------------------------------------------------------------

IDLE 0.5 released
by Guido van Rossum 25 Feb '00

25 Feb '00

After a delay of nearly half a year, I've finally released IDLE 0.5. I'll quote from the README after listing the URL: http://www.python.org/idle/ (Dear edu-sig members, please don't fill the edu-sig mailing list with detailed feedback on IDLE -- please use the newsgroup or the Python Bugs List. Discussion of requirements for adaptation of IDLE in education are welcome; please first check the TODO list (http://www.python.org/idle/idle-0.5/TODO.txt) to see if I've already thought of your request.) FEATURES IDLE has the following features: - coded in 100% pure Python, using the Tkinter GUI toolkit (i.e. Tcl/Tk) - cross-platform: works on Windows and Unix (on the Mac, there are currently problems with Tcl/Tk) - multi-window text editor with multiple undo, Python colorizing and many other features, e.g. smart indent and call tips - Python shell window (a.k.a. interactive interpreter) - debugger (not complete, but you can set breakpoints, view and step) USAGE [...] IDLE requires Python 1.5.2, so it is currently only usable with a Python 1.5.2 distribution. (An older version of IDLE is distributed with Python 1.5.2; you can drop this version on top of it.) COPYRIGHT IDLE is covered by the standard Python copyright notice (http://www.python.org/doc/Copyright.html). FEEDBACK For feedback, please use the Python Bugs List (http://www.python.org/search/search_bugs.html). --Guido van Rossum (home page: http://www.python.org/~guido/) <P><A HREF="http://www.python.org/idle/">IDLE 0.5</A> - the Integrated DeveLopment Environment for Python in Python.

Wash. D.C. Area: DCPIGgies, Mar. 13
by Jeremy Hylton 25 Feb '00

25 Feb '00

Notice to all Washington DC area Python users: We will be having our first DCPIGgies (DC Python Interest Group) meeting of the year on Monday March 13, 2000 from 7:30pm to 9:00pm at CNRI in Reston, Va. Speaker: Scott Cotton Static Type and Interface Checking for Python General Review and Fundamental Decisions Abstract ---------- This presentation reviews various possible ways of adding static type checking to python. The problem poses two questions: 1) What sort of static type checking system would be most appropriate for python? 2) By what means may static type checking be made optional? A decision tree for each question is presented based on a combination of type theory, an understanding of python, and properties that have become apparent in the development of a sample type checking system. Finally, we discuss some overall approaches that would maximize the benefits and/or minimize the drawbacks of adding optional static type checking to python. Scott will be speaking from 8:00 to 9:00pm. We will have food and introductions starting at 7:30pm. We may also have some time after the talk for Q&A with Guido and Barry on Python and JPython. Pizza, salad, and soda will be provided courtesy of Foretec Seminars. Please RSVP by email to jeremy(a)cnri.reston.va.us. I need to know how many people will attend and how many will be eating pizza. Directions to CNRI can be found on the Web: http://www.cnri.reston.va.us/directions.html Mailing list: There is a mailing list for people interested in DCPIGgies meetings; see http://www.python.org/mailman/listinfo/dcpiggies. This is a low volume list for announcing meetings, arranging to share rides, and other thrilling PIGgy topics. See you there!

Zope Weekly News - Wed, 9 Feb 2000
by Mike Pelletier 25 Feb '00

25 Feb '00

G'day, 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(a)digicool.com>, put 'ZWN' somewhere in the subject and remember to include URLs. Announcements * 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. http://www.zope.org/Products/Zope/2.1.4/Zope_214_release 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. http://www.zope.org/Members/brianh/UltraseekDA * "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. http://www.zope.org/Members/ngarcia/WampumGenerator Updates * 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. http://www.zope.org/Products/DA/SybaseDA/ * "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. http://www.zope.org/Members/Drew/Photo/ * Jonothan Farr <jfarr(a)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. http://www.zope.org/Members/jfarr/LocalFS Zope.org items * Chris McDonough <chrism(a)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. http://www.zope.org/Members/mcdonc/HowTos/gainenlightenment * "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. http://www.zope.org/Members/muesli/AuthByAddress * "jec" posted a HowTo which explains automating the starting and stopping (at startup and shutdown) of a Zope server on a Red Hat system. http://www.zope.org/Members/jec/startstop_howto_html * "vernier" has written a HowTo on creating custom Zope Debian packages. http://www.zope.org/Members/vernier/debian * "lalo" wrote a HowTo which describes how to use cron to trigger events on a Zope server. http://www.zope.org/Members/lalo/cron * Jens Vagelpohl <jens(a)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. http://www.zope.org/Members/jens/docs/zope_on_cdrom * Chris Petrilli <pertilli(a)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. http://www.zope.org/Members/petrilli/ConfidenceMetric http://lists.zope.org/pipermail/zope-ptk/2000-February/000169.html Corrections * Last week, the editor-in-chief of O'Reilly was mistakenly called "Frank Wilson". His name is in fact Frank Willison. == Mike Pelletier. -- ----------- 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 ------------------------------------------------------------
