by Serge Stinckwich March 13, 2015

March 13, 2015

Dear all, something that might interest some of you. There will be a datathon organized in Paris in collaboration with the MIT about data & development in African countries from April 7th to 9th. Some companies and NGOs will provide open data. Orange, the telecom provider will provided some data about communication between local antennas and also trajectories log of people. I have the idea of having a small team using ROASSAL for participating to the datathon and doing some nice vizualisations. Anyone interested to made a team ? You could find more information about this event here: http://simplon.co/blog/2015/3/7/datathon-data-for-development-rdv-les-7-8-e… sorry only in French. Regards -- Serge Stinckwich UCBN & UMI UMMISCO 209 (IRD/UPMC) Every DSL ends up being Smalltalk http://www.doesnotunderstand.org/

configuration browser descriptions
by Sebastian Heidbrink March 13, 2015

March 13, 2015

Hi! Here is another information based on my last beginners session. One should discuss if it might be useful and easy to implement to have a configuration browser that includes descriptions for the offered configurations. Beginners have no idea what Seaside, AltBrowser, Artefact,... stand for. Cheers! Sebastian

Question about NeoJSON
by Mariano Martinez Peck March 13, 2015

March 13, 2015

Hi, In this link: https://github.com/svenvc/docs/blob/master/neo/neo-json-paper.md I see an example of a custom mapping like this one: mapper for: TestObject do: [ :mapping | mapping mapInstVars: #(id name). (mapping mapInstVar: #timestamp to: 'created-at') valueSchema: DateAndTime. (mapping mapInstVar: #points) valueSchema: #ArrayOfPoints. (mapping mapInstVar: #bytes) valueSchema: ByteArray ]. I need something similar, but I need to store the original JSON string that was used to build a particular TestObject instance, in an instance variable of TestObject too. In other words, I need an instVar "originalResponse" in TestObject that would be set with the original JSON string. Any ideas how can I implement this? Thanks in advance, -- Mariano http://marianopeck.wordpress.com

When to use a stream for concatenating text..
by sergio_101 March 13, 2015

March 13, 2015

it seems that in more cases than not, i find that developers use a stream when concatenating some text strings. I am wondering if this is a smalltalk thing, or is there a real speed benefit when using streams in this way. Thanks!

Notebook/slideshow morph
by Torsten Bergmann March 13, 2015

March 13, 2015

>So I imported my old code (it was one week of test first experience). >I can open a slideshow, create page, drop morph on it, mark a page as >template and navigate. Is there a way to save and reload the slide show. Like in the good old squeak days (TM) with a *.morph file? Would be a nice addition to recreate some of the presentation and multimedia features known from Squeak now also in Pharo. Thanks T.

Settings Browser: Moose 5.1 exported settings raises error in Pharo 4.0
by Juraj Kubelka March 13, 2015

March 13, 2015

Hi, If I export settings from Settings Browser in Moose 5.1 and then open Pharo 4.0 image, it raises an error "GTGenericStackDebugger not found in SystemDictionaryâ. The problem is a setting: (Smalltalk at: #GTGenericStackDebugger) perform: #enableStackColoring: with: (true) which apparently does not exists in Pharo 4.0. I think if we want to share settings between images, it should ignore any setting that raise an error, right? Thanks! Juraj

I think phil is right. -vm-display-null is the question . it aborts the process. Does not matter wich vm and image are you using. For example i am trying pharo4 latest image latest vm. TIA Ing.
