He reported a 140 second GC pause. What are you seeing? (.i.e. can you post the full stats?) If this has disappeared then I suspect my Slang bug, which I fixed yesterday. But I will investigate. > Stephan > _,,,^..^,,,_ best, Eliot

What should we use instead? Array? nil when it’s empty? How about introducing some sort of a NilDictionary? Would anyone like to experiment?

Probably a bit more. Before loading, there were 172 instances of SmallDictionary. After loading, 558293, of which 30194 contain something. Stephan

mse loading looks slower :(
by Tudor Girba 24 Jan '16

24 Jan '16

Hi, I am doing some performance testing of Moose with the Spur VM on Mac. I tried to load an MSE file with ArgoUML 0.34 and on my machine it loads twice as slow with Spur than before: - PreSpur: 0:00:01:07.272 - Spur: 0:00:02:10.508 Here is the reference file: https://dl.dropboxusercontent.com/u/18323746/Tmp/ArgoUML-0-34.mse.zip And here is the script: [ MooseModel new importFromMSEStream: (StandardFileStream readOnlyFileNamed: (FileSystem workingDirectory / 'src' / 'ArgoUML-0-34' / 'ArgoUML-0-34.mse') fullName). ] timeToRun Do you get the same?

Specific Domain Visualizations: a glimpse of medicine public data released by governments
by Offray Vladimir Luna Cárdenas 23 Jan '16

23 Jan '16

Hi, As I told you before, I have been using Pharo/Moose/Roassal to approach certain problems by agile prototyping and visualization. It has been a really empowering community and technology and even a newbie can feel more eloquent talking to/with computers, so thanks as always. Here is the blog post with more details: http://mutabit.com/offray/blog/en/entry/sdv-infomed And here the tweet if you're in that network and want to reshare: https://twitter.com/offrayLC/status/689854446541611008 Hopefully I have been clear in the blog, but any advice to my almost self taught English, or proof reading or improvements are welcomed. I also hope putting proper credits to all the people involved in this visualization. And hopefully soon (at some point in February) I will be sharing some advances in the interactive notebook front also. Cheers, Offray

roassal2 seems to work well now
by Tudor Girba 22 Jan '16

22 Jan '16

Hi, With the latest development, Roassal2 seems to work well. For example, the rendering of the logical view of Glamour browsers was broken, and now it works well. This is great news. Is this just my impression? Do we know if there are still open issues with the FFI in this area? Cheers, Doru -- www.tudorgirba.com www.feenk.com "Every thing should have the right to be different."

Telescope
by Axel Lefaux 22 Jan '16

22 Jan '16

Bonjours, J'ai voulu installer Telescope sur Pharo 4.0. Hors lors de sa configuration, j'ai eu un Warning à propos de ce package qui dépend d'autre packages : This package depends on the following classes: RTObject RTView RTClusterLayout RTAbstractNormalizer RTShape J'ai donc téléchargé une image de Moose 5.1. L'installation réussie, j'ai essayé de suivre "Tutorial end-user" et lors du premier exemple, le message n'était pas compris, le receveur du "new" est "null". Cordialement, Axel Lefaux.

[ann] spotter processors as settings
by Tudor Girba 22 Jan '16

22 Jan '16

Hi, We now have a new little feature in Spotter. Take a look: Basically, you will get a setting for each processor defined in the image. This happens dynamically. If you disable the setting, the processor will not be available anymore. Please give this a try and let us know what you think. We would also like a code review related to the way we deal with dynamic settings. Right now, the magic is done in GTSpotterExtensionSettings (this is real magic - read the class comment), but the current solution relies on a doesNotUnderstand: to maintain the list of disabled processors. I would more prefer it if we could create a DynamicSettingDeclaration that would be able to pass arguments to one central selector.

Script of the day: Charting several data sets
by Alexandre Bergel 21 Jan '16

21 Jan '16

Hi! Just in case you did not know, we have a MultipleData to chart using bars several data sets. For example: -=-=-=-=-=-=-=-=-= b := RTGrapher new. d := RTMultipleData new. d barShape color: Color blue. d points: #( #('hello' 1 2 1) #('world' 2 4 2) #('bonjour' 3 5 4) #('Gutten Morgen' -1 4 -5)). d addMetric: #second. d addMetric: #third. d addMetric: #fourth. "d barChartWithBarCenteredTitle: #first." d barChartWithBarTitle: #first rotation: -30. b add: d. b -=-=-=-=-=-=-=-=-= Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

Problem with Rubric?

Hi! I regularly see very obvious problems with Rubric. I have just downloaded the latest Moose image and typing in a Playground and get an exception in: RubTextComposer>>recomposeFrom: start to: stop delta: delta Am I the only one?
