Hmm, I was about to write that the goal of collective behavior is to model the behavior of the groups (like you demoed at ESUG), and I wanted to ask how do you store this behavior in Store. Now I see that I misunderstood completely. From the arguments below, I believe it is not really worth the trouble.

[ANN] moose.unibe.ch

by Tudor Girba

Hi, A new webpage based on Pier is up and running at: http:// moose.unibe.ch . Feedback is welcome :). Here is an overview: -- the front page is supposed to offer all sorts of entry points into the contents. -- publications are read from a bib file that contains the entries from scg.bib that are marked as moose-pub. For each publication a page is created whose title is the title of the paper, the url is the key of the entry and the tags of the page are the keywords of the entry. This is useful for the publications cloud that you can see on the front page. I spent quite some time to add missing moose-pub keywords and to add several other keywords. Now that the keywords are actually used, perhaps we will have an incentive to add some more for our publications :) -- on the front page there is a place for a highlight that is randomly shown. At the moment there are just 2 movies with Mondrian. It would be cool to have more such videos with your nice tools :). To add your highlight, you have to add a page below randomhighlight similar to: http://moose.unibe.ch/randomhighlight/videomondrianbasics -- on the tools page, each tool has a page allocated. You can add tags in each tool page, and these keywords are taken into account in the tools cloud. For example, you can specify whether the tool is in- visualworks or in-java. -- there is a news feed. At the moment it is broken due to some Apache settings or something :), but it should be available at: http://moose.unibe.ch/news?view=PBEntriesRssView -- the site contains the content from the Smallwiki page. I also took the liberty to copy some content from personal sites (like codecity or softwarenaut). I hope that is Ok. -- you can follow the changes via RSS: http://moose.unibe.ch/?view=PRChangesRssView -- the webpage is persisted in the image, and the image is scheduled to be saved under a different name 1 hour after a change. You need a user to change the page, please ask me for one. There are two types of users: admin and editor. The admin can do everything, while the editor can just edit :). You will probably get an editor user. Further details about how to edit the site can be found at: http://moose.unibe.ch/varia/howtoedit This is just version 1. There are several things that are still in plan: - make publications updated periodically from external urls. Currently it is updated manually. - make the tool page a special component that has explicit links to publications and developers. The tool should also have an explicit license field. - port the Store queries from VW to Squeak to create activity reports. - add last update information on each page. - work on the css to make it use a better alignment Cheers, Doru p.s. I would like to thank Lukas Renggli and Adrian Lienhard for their help and patience :). -- www.tudorgirba.com www.tudorgirba.com/blog "We cannot reach the flow of things unless we let go."

problems with loading moose development

by Richard Wettel

Hi, I am trying to load my prerequisites (MooseDevelopment) and first I get this: "Warning: Package "Meta-FM3-Model" cannot be loaded. The following classes cannot be loaded because their environment is not in the image nor in the package being loaded: MultivalueLink (environment path: Root.Smalltalk.Meta)" Followed by a bunch of unloadable definitions in Meta. After loading everything I could, I try to initialize the meta descriptions and I get: "Unhandled exception: Message not understood: #on:opposite: UndefinedObject(Object)>>doesNotUnderstand: EMOF.Class>>initialize ..." Could you guys fix it? Thanks, Ricky

Moose Suite Loader

by Timo Gienger

Hi Moose-Dev-Team, i´m currently trying to install Moose with the Moose Suite Loader in Visual Works 7.5. When i try to download the suite, the first dialog tells me "currently disconnected, do you want to reconnect?" so sure i want, so clicking yes leads me to the next problem that tells me "A problem was detected. Please try again". The status window in VisualWorks tells me: " visualnc.im created at April 17, 2007 10:52:24 amERROR: current transaction is aborted, commands ignored until end of transaction block ERROR: current transaction is aborted, commands ignored until end of transaction block ERROR: current transaction is aborted, commands ignored until end of transaction block ERROR: current transaction is aborted, commands ignored until end of transaction block ... " I hope you can help me to install the Moose Suite because i want to use it in my diplom-thesis about software-metrics. I wanted to use the MooseSuite in a chapter about visualizing metrics in the software development process. Thanks in advice! Greetings Timo Gienger
