I have risen to the challenge: http://www.zope.org/Members/webmaven/zope-banner-1.gif The file size is 13k, it's a seven frame animation. Please note that this is only a first draft, and I am still trying to improve the verbiage, layout, and timing of the animation. DC guys, this would be easier if I had source files for the logo and the fonts that you are using for your logo.

Announce: Where's the zope? => new version SwiftGenerator
by Jason Cunliffe 30 Oct '99

30 Oct '99

Hello I hope you do not consider this off-topic. This post is intended as food for thought and not advocacy. Zope is notable for its flexible handling of web object structures. But the web (and especially the commercial web) is notable for its hunger for graphics and multimedia. One of the few systems even attempting to create a dynamic platform for this is the combination of Macromedias 'Flash Generator' http://www.macromedia.com/software/generator/ which is often combined with Allaire's ColdFusion... So where does Zope fit in?? 1. SERVER-SIDE MEULTIMEDIA The intrepid Olivier Debon has posted his latest version of SwiftGenerator http://www.swift-tools.com/ It is an obvious candidate tool for use with Zope. Unfortunately, like Macromdedia's own Generator, SwiftGenerator does not generate vector garphics from nothing. It is rather a programable editing tool for prepared garghics and interactive vector graphics. Text can be generated and atrributes and relationships likewise. Both 'Generators' need Macrodmedia Flash as an authoring tool to prepare content. SwiftGenerator has a huge price advantage.[free download] 2. ZOPE MISSING ??? Either way, it is interesting to note that Zope/Python are _not_ present on the listing at the Generator Developers' Network homepage: http://www.gendev.net/ 3. C LIBRARY FOR WRITNG FLASH MOVIES To generate openSWF(FLash) vector files without the Flash applications, it would be necessary to apply/extend Parul Heberli's openSWF library. This could be done via Python and then used as advanced multimedia vector version of PIL (Python Imaging Library). http://reality.sgi.com/grafica/flash/DOC.html 4. RESOURCES http://www.gendev.net/swf/ The SWiFF Info Center has several useful links including to source for C++ swf parser Consider the spec list below. How could/should this be implemented/surpassed using Zope ? ---------------------------------------------------------------------------- --------- Swift-Generator is a simple replacement for Macromedia Generator utility. It aims at generating dynamic Flash content. Swift-Generator can replace: · Texts (size, alignment, kerning, color, transparency and font), · Textfields (Flash 4), · Fonts, · Sounds, · Images, · Movie Clips, · Action parameters (in frames or buttons). It can be used as a CGI program for HTTP servers like Apache, or just as a separate utility called to produce a new Flash file whenever it needs to be updated (crontab, schedulers, ...) · Platforms · Linux (x86/MIPS). · FreeBSD 3.1 (x86). · Solaris 2.X (Sparc). · Windows 95/98/NT. · MacOSX. · OS2. · BSDi 3.1. · Flash Operations · Text replacement · Text color and height modification · Text Kerning and Vertical spacing · Text Alignment · Font replacement · Sound replacement · Movie Clip replacement · Image replacement · Accept either Template or Flash files · Variable substitution · Action parameters substitution for: · GetURL (URL/Target) · FS Command (Command/Parameters) · Load Movie (URL/Level#) · Unload Movie (Level#) · Tell Target (Target) · Generation · Script based · CGI 1.1 compliant · Off-line generation · Generate size-optimized flash output · Web · Referer control list · Success Stories with: · Apache (Unix/Win32) · Microsoft IIS · Personal Web Server · Sambar Server · Cold Fusion · Xitami (Unix/Win32) · Roxen · .... ------------------------------------- - Jason ------------------------------------------------- Jason Cunliffe <jasonic(a)nomadicsltd.com> NOMADICS.STUDIO(Design Director) Geo-Digital Arts and Technology Le Vieux Moulin, Route de Mons 83440 SEILLANS, FRANCE Tel: +33 (0)4 94.76.98.72 Fax: +33 (0)4 94.76.97.77

Re: [Zope] WAP/WML for Cell Phone Wireless Web?

The way I was thinking about it was to have two sets of template pages - one produces HTML, the other WML. The alternative is to have one set that produce XML, and convert them on the way out of the system. You'd probably also have to restructure your web applications to better suite the WML model. The other thing you need is a phone company willing to let you supply them WML so that they can send it to the phones (there's WAP-over-SMS, but I don't want to think about how slow and expensive that would be). -- Anthony Baxter <anthony(a)interlink.com.au> It's never too late to have a happy childhood.

gadfly commits and checkpoints Re: [Zope-dev] Re:

However it can be mitigated by doing checkpoints less frequently than commits. By default every commit generates a checkpoint, but for better transaction performance you might want to have one checkpoint for every 1000 commits if the database is largish.

Re: [Zope] Generating unique keys
by gtk 30 Oct '99

> Bugger. They're not pickle-able. Now, here's a funny. I put together a seperate module called ShrubLock which acquires its own lock, then used it to [attempt to] prevent more than one instance of my Shrubbery from entering a particular piece of code which checks in a non-Zope database to figure out what number it should use next. I was still getting Z2 conflicts, so -- figuring that each class had its own ShrubLock, or something wierd -- I whacked in a lot of debugging code to figure out what was going on. The problem isn't name conflicts, I've figured out. It's the fact that Zope just can't deal with more than one request trying to modify a single object -- including, the ObjectManager I'm trying to add things to. Regards, Garth. -- <gtk(a)well.com>

Are you by chance trying to access Zope from another machine other than the one you installed it on, and if so, did you set the domainname in the /var/zope/access file to permit access from that remote machine? The RPMs default to localhost only. I would have said you might have not configured Apache correctly to pass thru authentication info, but if you have the same problem with standalone ZServer then Apache is not involved. I really need to patch Zope to log reasons for authentication failures, so we can diagnose these things. I also need it to diagnose FTP login failures, of which I see a lot, due to the odd (but necessary) way Zope has of accepting a username/password and then re-applying it to each dir/file you access via FTP. You -think- you logged in correctly, but didn't and can't get info from Zope on what went wrong. -Jeff Rush

objectValues('External Method')

Duh.. Well answering my own previous question => > > Q2: To create a nice linked list of External Methods. What is the syntax for > 'External Methods' similar to <dtml-in objectValues(['Folder', 'Image'])> > 'ExternalMethods' or'External Methods' don't work... The meta_type is 'External Method' Apologies.

Password 2nd Posting
by Daniel G. Rusch 30 Oct '99

30 Oct '99

I've posted this before and got no reponses, so either it can't be done, or it's so trival no one has bothered to responed? Are all of you manually maintaining users? I'm trying to build an interface to allow users to change their passwords (only their passwords not roles of course). I have no problem getting the new password and changing the old one. The problem is a professional site would ask the user to enter their current password and verify it is correct before they allow the user to change their password. The question then is does anyone have any ideas on how to compare a user entered password to what Zope has stored as the password? Thanks, DR
