Zope Weekly News - Wed, 13 Oct 1999
by Amos Latteier Oct. 21, 1999

Oct. 21, 1999

Hi, Yet another active week in Zopeland. The Zope community continues to churn out great ideas and software at an incredible rate. Its very exciting to watch existing Zope projects like Squishdot mature and new projects like PythonMethods spring up. * Ng Pheng Siong posted his additions to ZServer which allow it to do SSL with the M2Crypto Python package. Very cool indeed! http://www.zope.org/pipermail/zope-dev/1999-October/001803.html http://www.post1.com/home/ngps/m2 * Bill Anderson updated his Knowledge Kit to version 1.6.3. Knowledge Kit is a Zope Product for creating knowledge bases. http://www.zope.org/Members/Bill/Products/KnowledgeKit * Butch Landingin released Squishdot 0.3.0 Squishdot is a very popular Zope Product for running Slashdot-like discussion sites. Many cool Zope sites including Technocrat.net run Squishdot. http://www.squishdot.org/ http://www.zope.org/pipermail/zope/1999-October/011663.html * Following up on his excellent ZODB work last week, this week Ty Sarna posted a CompressedStorage class which can be layered over another ZODB storage to provide pickle compression. http://www.zope.org/Members/tsarna/CompressedStorage/Announcement * The tireless Jeff Rush updated his Zope RPMS for Zope 2.0.1. He also compiled the ZODBC database adapter for use with Solid Technology's commercial SQL database product (v2.3), under Linux. http://starship.python.net/crew/jrush/Zope/ http://starship.python.net/crew/jrush/Zope/Zope2.html#ZODBCDA * Evan Simpson updated Python Methods to version 0.1.4 http://www.zope.org/Members/4am/PythonMethod * Stuart Bishop released Logger 1.0.1 which allows you to write to Zope's log files from DTML. This can be quite useful for debugging and error logging. http://www.zope.org/Members/Zen/Logger * Amos Latteier posted a XML-RPC How-To. This link immediately showed up to www.scripting.com and www.xmlrpc.com. http://www.zope.org/Members/Amos/XML-RPC * Jason M. Thaxter pointed out that Zope is mentioned in a Tim O'Reilly piece. http://xml.com/pub/1999/10/tokyo.html * Jonathan Corbet and Roman Milner pointed out that www.HireTechs.com has launched an auction site using Zope, though they do not identify the site as Zope-powered. http://www.newsalert.com/bin/story?StoryId=Cn_1SqbKbytaXmZi * Chris McDonough pointed out that Python's creator Guido van Rossum mentions Zope as in his latest interview. http://www.oreilly.com/frank/ * Andy Dustman released MySQLdb-0.1.1 which provides access to MySQL from Zope. http://www.zope.org/pipermail/zope/1999-October/011978.html * Chris McDonough mentioned that Linux.com has donated space for a Zope ad. Lots of discussion ensued about what the ad should say. http://www.zope.org/pipermail/zope/1999-October/012037.html * The indomitable Chris McDonough produced an interesting comparison between Zope and MS SiteServer. http://sharon.iqgroup.com/zopevssiteserver.html http://www.zope.org/pipermail/zope/1999-October/012115.html * Brad Clements expressed interest in taking over NotMail development. Go Brad! http://www.zope.org/pipermail/zope-dev/1999-October/001771.html As always this summary cannot do justice to all the frenetic Zope activity, but it can perhaps highlight a few interesting items you may have missed. See you next week. -Amos == Amos Latteier mailto:amos@digicool.com Digital Creations http://www.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 ------------------------------------------------------------

Zope Weekly News - Wed, 20 Oct 1999
by Amos Latteier Oct. 21, 1999

Oct. 21, 1999

Hello, It's been yet another jam packed week for Zope. There were community advances in Zope development, documentation, and advocacy. Keep up the good work Zopistas! * Atlanta Linux Showcase was held this week and it included a talk by Digital Creations' Paul Everitt, and a Zope Birds of a Feather session. http://lwn.net/1999/features/ALS/ * There was lots of discussion about a Linux.com community ad for Zope. Chris McDonough got things rolling and it snowballed from there with many creative ideas. Then the conversation turned to the merits of the name 'Zope' which many folks seem to think is actually reasonable despite sounding somewhat silly. http://www.zope.org/pipermail/zope/1999-October/012037.html http://www.zope.org/Members/webmaven/zope-banner-1.gif * Martijn Faassen announced XMLWidgets 0.2. This release includes a number of demos which reveal that this is shaping up to be a very powerful Zope product. Go Martijn! http://www.zope.org/Members/faassen/XMLWidgets * Gerard Mulot announced a complete Zope application available for downloading. It sounds like it could be a good source of Zope examples. http://www.zope.org/pipermail/zope/1999-October/012252.html http://www.zope.org/Members/gerard/centaur/index_html * Ian Clarke started a discussion about the future of Zope and Zope clients. One could develop many types of Zope clients such as Java applets, Mozilla XUL apps, or local apps coded in almost anything which spoke to Zope over XML-RPC. Of course a full Zope client would be a major undertaking and no one so far seems to be seriously planning such a project. * Pavlos Christoforou announced a How-To on storing information outside the ZODB. http://www.zope.org/pipermail/zope/1999-October/012374.html * Zope veteran Martijn Pieters announced that he'll be giving a presentation on Zope at the Dutch Unix Users Group (NLUUG). http://www.zope.org/pipermail/zope/1999-October/012393.html * Johan Carlsson announced a ZIE update and Offline editor availability. http://www.zope.org/pipermail/zope/1999-October/012400.html * Evan Simpson announced SiteAccess v0.1.0 which now allows virtual hosting. http://www.zope.org/pipermail/zope/1999-October/012531.html * Ty Sarna announced Tranalyzer 1.0, a utility for analyzing and examining ZODB files. It includes the ability to watch transactions being committed to the ZODB (think tail -f). Can Ty continue to release yet another cool Zope tool *every* week? Tune in next week to find out. http://www.zope.org/pipermail/zope-announce/1999-October/000050.html * The Zope Documentation Project continues to work tirelessly on their ZBook project. http://zdp.zope.org/ZBookStatus/ * David Kankiewicz and the ZQR team announced ZQR 0.8 If you aren't yet hip the ZQR (Zope Quick Reference) you should definitely check it out. http://www.zope.org/Members/ZQR * Stuart Bishop posted a How-To which describes Zope argument marshalling. Very useful! http://www.zope.org/Members/Zen/howto/FormVariableTypes * Lalo Martins released an experimental Banner Ad product. http://www.zope.org/Members/lalo/BannerFolder See you next week. -Amos == Amos Latteier mailto:amos@digicool.com Digital Creations http://www.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 ------------------------------------------------------------

agrepy 1.1: Python port of agrep (string matching with errors)
by mw263X＠quetico.ccsr.cam.ac.uk Oct. 1, 1999

Oct. 1, 1999

Agrep, written by Sun Wu and Udi Manber (described in "Fast Text Searching Allowing Errors", CACM, 35(10), 1992), is a suite of C functions which together perform various string matching operations under UNIX (i.e. specified at the commandline). For example, agrep is able find matches despite differences due to American versus British spelling agrepy takes agrep from its user level setting and makes it available as a Python module. Specifically, what this port implements are those functions from agrep relating to inexact matching of text strings which contain no metacharacters. For example, agrep is able find matches despite differences due to American versus British spelling. apgrepy also extends agrep in the following sense: given a pattern and a text string, agrepy and returns a list of all, non-overlapping pairs of text indexes such that the start index is the first character of the text that matches the earliest pattern character exactly, and the end is the last text character that matches exactly. The end index of each match is 1 place greater than the actual index so it can be immediately used to construct a slice. (agrep itself is content with recognizing that the input line contains a match, but does not say where or differentiate multiple matches.) agrepy 1.0 (July 1999) had an end-of-text bug in the short pattern module, while both the long and short pattern modules had problems at times finding the precise ends of a match. There also can be a genuine ambiguity specifying the ends of match which has equal number of errs. The methodology now is that the original algorithms find the ends of matches fairly accurately, and a separate, recursive function firms up the end position The authors of the original programs are Sun Wu and Udi Manber, as described above.

"Das Python-Tutorium 1.5.2" finished!
by Dinu C. Gherman Oct. 1, 1999

Oct. 1, 1999

The German translation of Guido's Python tutorial is finally finished now, after considering many suggestions from preview readers and correcting many typos! Please note that the standard Python LaTeX tools, coming with the Python standard documentation distribution appear not to be sufficient to convert the LaTeX source code into HTML! It is planned to write a README describing what was needed to still get it done (but it wasn't me who did the conversion). This README will be included in the following folder, too, as soon as it exists. You may find "Das Python-Tutorium" here: http://starship.python.net/crew/gherman/publications/tut-de with a short paragraph describing it on: http://starship.python.net/crew/gherman/ If you have any special comments or corrections, please con- tact me directly instead of approaching the Python-De mailing list!
