basil
by Tudor Girba 22 Mar '11

22 Mar '11

Hi, I recently remembered that Basil, the library for flash export built by Lucas , was ported by Lucas Streit in Squeak. I just gave it a try and there is only one test that fails. Also, the examples from Basil-Applications seem to work as well. In VW, we had a binding for Mondrian: http://www.moosetechnology.org/tools/vw/basil If you want to give it a try, you can find it at: Gofer it renggli: 'unsorted'; package: 'Basil'; load Cheers, Doru -- www.tudorgirba.com "What is more important: To be happy, or to make happy?"

Hi, moosetechnology.org would benefit from more community effort :). For example, up to now, I (and sometimes Simon) was basically the only one updating the news content. Anyone interested in participating? Cheers, Doru -- www.tudorgirba.com "Reasonable is what we are accustomed with."

[hapax] tdm weighting
by Alberto Bacchelli 21 Mar '11

21 Mar '11

Hi all, I am reproducing some experiments I did time ago, and I am again using Hapax (latest version for VW). FYI, I just noticed that there could be an issue in how the weighting in the TermDocumentMatrix is evaluated. I attach the method here for convenience: TermDocumentMatrix>>weight | newMatrix | newMatrix := SparseRowMatrix new: matrix dimension. matrix rows with: newMatrix rows do: [ :row :newRow | | globalWeight | globalWeight := globalWeighting forTerm: row. row doSparseWithIndex: [ :each :index | newRow at: index put: (localWeighting forValue: each) * globalWeight ]]. matrix := newMatrix. this method should apply the tf-idf weighting [1] to the matrix. This weighting is composed of two parts: a global weighting (i.e., idf: the more a term is common, the less its weight) a local weighting (i.e., tf: each term is normalized on the number of terms appearing). The global weighting is correctly done in the line: globalWeight := globalWeighting forTerm: row. while the local weighting is NOT correctly done in the line: newRow at: index put: (localWeighting forValue: each) * globalWeight in fact, the "localWeighting forValue: each" will always return "each" back. This means that it simply does not apply any local weighting. Right now I am working on fixing this issue. Please let me know if I am wrong, or if you have an elegant solution :) Cheers, Alberto [1] http://en.wikipedia.org/wiki/Tf%E2%80%93idf

Hello, When I want to open a magritte presentation, glamour always open it in a very small size (in a 'scrollPane'), without filling the whole space of the cell. Does anyOne know what could be the problem or what could I do to solve that?

test crashing the cog vm
by Tudor Girba 21 Mar '11

21 Mar '11

Hi, Alex recently wrote a test in Moose that seems to crash the Cog VM at least on Mac. How to reproduce: - download the following image http://dl.dropbox.com/u/18323746/Tmp/moose-crashing-cog-jit.zip - execute the following code in the workspace (already provided in the image) cls := Class new superclass: MooseElement; yourself. cls compileSilently: 'mooseName ^ 1/0'. element := cls new. - I used all of the followings and they all crashed: https://pharo-ic.lille.inria.fr/hudson/view/Cog/job/Cog%20Mac%20Cocoa/4/art… https://pharo-ic.lille.inria.fr/hudson/view/Cog/job/StackVM%20Mac%20Cocoa/2… http://www.mirandabanda.org/files/Cog/VM/VM.r2370/Cog.app.tgz http://www.mirandabanda.org/files/Cog/VM/VM.r2361/Cog.app.tgz The strange thing is that the crash only happens when we subclass MooseElement, but not another class. Could someone take a look? Cheers, Doru -- www.tudorgirba.com "Every thing should have the right to be different."

Hi, I played a bit last night and built this visualization showing how we collaborated on papers around Moose (the info came out of Citezen): http://www.moosetechnology.org/news/paper-collaborations Cheers, Doru -- www.tudorgirba.com "Problem solving efficiency grows with the abstractness level of problem understanding."

200+ publications
by Tudor Girba 16 Mar '11

16 Mar '11

Hello everyone, We now have more than 200 Moose-related publications with new publications coming at a rate of 25-30 publications per year. That is simply great! It is a real privilege to be part of this. Cheers, Doru p.s. Please take a look at the publications. If you feel that some are added without merit, or some are missing, please let me know and I will correct the situation. You can use the search facility (make sure you use moose-pub as one of the keywords): http://www.moosetechnology.org/docs/publications/bib?query=moose-pub -- www.tudorgirba.com "Don't give to get.

Re: Metamodel changes and Moose versionning
by Usman Bhatti 16 Mar '11

16 Mar '11

Hi all, I have known and used moose for some years but now I am stepping into developing tools with it. So, I had a small experience with the changes in the model. We developed some code to calculate package metrics and the next week the code doesn't work. After spending a few hours on debugging and a helping hand from Jannik, I could resove the problem that came from the change in parentType. Although the problem was small, it took a newbie like quite some time to resolve. I knew all the methods regarding metrics calculation but when it came to meta-model I wasn't too sure what was going on. Moreover, soon I am going to start work on Csharp MSE extractor. So, once we have the mse extractors for different langs, any changes to meta-model would require some work to align these extractors. So, my suggestion is that any changes to the FAMIX meta-model should be considered major because they require quite a bit of effort behind the scene to align the tools using it.

unregistering from announcements in glamour
by Tudor Girba 16 Mar '11

16 Mar '11

Hi, It looks like we finally managed to get Glamour to unregister properly from model announcements (thanks to Henrik and Esteban). It would be nice to have more tests around this. Jorge started to use his nice meta-engine to provide some fine grained instrumentation so that we can test this in a different way. In the meantime, let us know if you still have problems with garbage collecting a model (MooseModel or otherwise) after opening a Glamour browser. This is a critical point in getting Glamour to be used on a larger scale. It would be so great if this would actually work properly :) Cheers, Doru -- www.tudorgirba.com "We cannot reach the flow of things unless we let go."
