Hi! I would like to discuss about MooseModel class>>ownerOf: I understand the implementation. But this leads to a strange behavior. For example, the following fails time to time: element := MooseEntity new. self assert: (element mooseModel isNil). It fails since I have written tests about the id generation. And the element may have a mooseID of a previous object. What should we do? I can remove the tests about the ID generation, but removing tests is never good. Would it be possible to use the privateState to store the mooseModel? Are the hypothesis why we have changed the reference of the mooseModel still valid?

Fixing yellow tests
by Alexandre Bergel 23 Mar '11

23 Mar '11

Hi! One of the test is yellow because of the mismatching there is of mooseName DudeDuplication>>mooseName ((signature isNil or: [ referenceCode isNil ]) or: [ duplicateCode isNil ]) ifTrue: [ ^ 'Error' ]. ^ 'Chain: ', signature, ' between: ', referenceCode mooseName, ' and ', duplicateCode mooseName It is wrong to override mooseName. mooseNameOn: should be overridden instead. Shall I update mooseName into mooseNameOn:?

Hi! When I use the wizard of Hapao, I get an error. You can reproduce the problem by doiting and pressing next: -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= | v control firstPane packagesList part1 lastPane part2 | control := WizardControl new. firstPane := WizardFirstPane new. lastPane := WizardLastPane new. control addPane: firstPane. control addPane: lastPane. part1 := TextPart new inGroupboxNamed: 'Hapao: select the packages to analyze'. packagesList := PackageOrganizer default packageNames asSortedCollection: [ :a :b | a < b ]. part2 := MultiSelectionListSelectorWithSmalltalkExpression on: packagesList. firstPane addPart: part1 associatedTo: #packagesSelected. lastPane addPart: part2 associatedTo: #packagesSelected. control open -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Unfortunately, I am not able to write a test for this since the window is modal Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

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

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."
