Hi! While browsing the Web, just found Yet Another Web Application Development Platform. Now it is SmartWorker, and it is based on Perl: http://www.smartworker.org/ License will change in near future for (I think) more open. Web Developmnet Platforms? Aren't there a little too many of them? :) Oleg. ---- Oleg Broytmann Foundation for Effective Policies phd(a)phd.russ.ru Programmers don't die, they just GOSUB without RETURN.

Try renaming the file to ZODBC-3.1.0b2-win32.x86.gz, then unzipping. It contains a tar file. With Winzip, it will then untar the tar file. With something else, you may have to unzip the tar file, then untar it separately. You may have to tell the unzipping program what the right file extension is. Tell it tar. The tar file contains everything. You untar it into the Zope directory, and you are supposed to get a new directory called Zodbcda under the lib/python directory. The files go into that directory. I just went through this, and it worked for me. Thomas Passin >BUT, there is no "ZODBCDA.tgx" file.

Zope Front door thoughts
by Jason Cunliffe 27 Oct '99

27 Oct '99

Message: 28 [snip] > I'd like to suggest we should all, as a community, take a fresh look at > the front door on the Zope web site and suggest improvements to make > sure that new prospective users can get an *immediate* grasp of Zope's > unique "selling" propositions. This is a very, very important thread to me. I'm looking for two things: o What questions should the Zope.org home page, and pages one click away, answer? o What are some effective ways to answer those questions? --Paul hmmm...jumping in here... In the zope lightbulb department, I detect two main cognitive problems and several syntactic/presentation ones: 1. zope = zen object publishing environment. You have to do it to get it. And the more you do the more you get it.. This makes it difficult to explain because there is a dynamic process implicit in re-use, development, adaptation etc. But most textual presentations, no matter how lucid they are, do not capture or convey very well the dynamic nature of either the problem or the solution. Anyone who has been there, done that for a while (even a very short while) 'gets' something others don't because they have an built up an experience of the way in which these tools can help one _think differently about the problem, and also they know the momentum gained from _working with them. It is not just faster to do stuff this way, it is better smarter nicer. Quality of life issue in a sense. 2. Relativistics - As I see it the nature of zope is that object structures work in two directions by hierarchical ordering and by acquisition. I find the term 'Acquisition' is both annoying an misleading name. the The word implies some commercial exchange, but if I have understood it correctly, the metaphor is much closer to the idea of genetics and how genetic traits are affecting by the dynamic conditions of the environment. That the context of some zope DTML code can change its _behavior_ I belive is the key, but on the surface [read FRONT page} this is not so evident. Because zope depends upon a relativistic object model it makes it hard to explain unless one has some experience. The nature of all relativistic explanations is that they depend upon dynamic subjective personal point of view - To take a favorite example of mine - giving someone precise coordinates or a map with a red line showing the route options. As opposed to telling them: " go down the street and then turn left after the traffic lights. .. When you get the bend in the road, cross over and ask anyone there which is the zope.org cafe..." Both approaches are valuable., The overview and the headsup relative model. The web and the web object model is tantalizingly relativistic. There is no map yet and perhaps never could be. Yet zope zen says if the web were built out of these kind of objects it could perhaps map itself. zope objects are like little piece so this maps but as yet there is no map for zope itself... "If you don't know where you are going, you might just end up somewhere else" - Yogi Bera <DTML-PROPOSAL: Make a set of animated zope 'map' to visualize the system and its use.> What would perhaps really help people understand zope is an animated map conveying the relativistic nature as well as the structural and functional key components. the zope.ORG front page is singularly lacking in visual anything. Yes nice simple stripped down functional site, but zope requires a very spatial/logical understanding. And these concepts may be more clearly presented initially using some dynamic spatial metaphors. [hint1: try modelling it on a napkin, and then again with Macromedia Flash] {hint2: try modelling it schematically in Zope but splitting the screen horizontally say with HTML above and DTML below simultaneously or make a simple DTML where a rollover or click() event swaps or expands the DTML to its HTML result. Yes one effective 'message' of the zope.org site is not_hype, not_'flash' but another is that is yet another brillaint tool beloved by cool programmers but which is not exmplainable or presnedtable to non-programmers. You can list features till your are blue in the face, but that won't help some people, especially when ther are soem paradigm dhifts involved. And if they are not programmers, perhaps you need to consider prallel techniques or media to get the message across. Zope is part of the invisble magic of the web. What you see is not what you did WYSINWYD. And there are two audiences or processes - visible and invisible. The relationshuips betwren these needs to be made clearer - by text and by illustration . Q: When the key developers of Zope and its ancestral components were thrashing this stuff out, did they whiteboard or brainstorm on napkins? If so what did they draw? And if they did'nt but you have lunch today, what will you sketch to explain zope? As for the overview, what would the indispensable ZOPE POSTER look like? Perhaps that is a FRONT DOOR ITEM. Perhaps the poster is a sort of flattened all menus exposed type of animated movie. Zope is highly interactive - by design, concept, practice and by result - but there is nothing on the front door which expresses this yet.. Except for the crucial fact this community is very busy learning and doing it! In general the nature between play, learning and design has been officially undermined for many years. OOPS has been threatening to restore respect for these essential creative human actions, but always seems to get bogged down in jargon and technology. Zope is brilliant because it does let one play around with idea, the tools and the structure, learn, and thus iterative design further and better. PATTERNS A potential major breakthrough is this dilemma, has been the rend towards Design Patterns - the adoption by oops programmers of Christopher Alexander's inspiring architectural philosophy. In fact Zope DTML has the beginnings of a very friendly design pattern language. I can easily imagine a ground breaking book on 'Creative Problem Solving and Design Patterns Zope'. Hope something here makes sense to you.

BUT, there is no "ZODBCDA.tgx" file. The only file that comes with the ODBC download (a gz file) is "ZODBC-3.1.0b2-win32.x86" there is no extension. When I extract this file to the Zope folder I do not see ZODBCDA on the products list on the control panel. Any assistance would be GREATLY appreciated

I ran into some problems and have the fixes. I think they should be added to the install.txt file or even a FAQ. Who is in charge of this?

27 Oct '99

I am almost there. I am running as root I expanded the source code. ran python w_pcgi.py It compiled fine. changed the owner on the var directory to nobody. chown nodoby var This should give it RWX in the entire directory. Ran "./start" I get an error: "permission denied: '/home/zope/Zope-2.0.1-src/var/Z2.pid'" It does write some pid files: zProcessManager.pid, pcgi.pid What else should I change. thanks, Geoff Nordli

My zserver.sh (link to zserver_wo_pcgi.sh) still has the 'export ZSYSLOG="anything" line, but I still get the problem if I just run the "python z2.py" line from the command line without the ZSYSLOG_SERVER env var. No big deal once I knew what the problem was, but there should be a mention about syslog -r in LOGGING.txt & maybe the faq.

Exploring Pyrhon External Methods and wanting to upload a lot of python modules and keep them tidy. For example imaging files into Extensions to do live thmumbnailing and image composition. So far have not been too successful with python scripts importing form the Extensions folder... Any sepcial tips about calling modules from python in External Methods? Are subfolders allowed in 'Extensions' ? Thanks - Jason

I can't post a reply to a Confera message. I'm running Python 1.5.2, Confera 1.2.0, and Zope 2.0.1. Similar errors have been posted in Zope archive mailing lists and bug reports, but no solution or patch. Does anyone know of a fix? Thanks. ----- Here is the error generated: Error Type: AttributeError Error Value: regs: , ...

what user and group to use for zope install
by Geoff Nordli 27 Oct '99

27 Oct '99

Should I create a user, and group for zope install? Where should I put the installation? "/usr/local/zope" Should the user/group own Zope's entire directory structure. In the documentation it says that the user that starts Zope must own the var directory. How do you know what user is being used to start Zope, and how do you control it. I did the compile using "root". What kind of security implication is having root own the zope directory. If I want to add additional components to zope like mysql, apache, and whatever--does this affect the user that zope runs under? thanks, Geoff Nordli MCT, MCSE, Master CNE, CCA, MCP, A+ G Nordli & Associates 749 Robson Dr. Kamloops BC, V2E 2G7 Phone: 250-314-7354 E-mail to pager: 2503147354(a)pcs.cantelatt.com E-mail: geoff(a)gnaa.net
