GT Inspector: Inst Vars Not Bound
by Sean P. DeNigris 10 Apr '15

10 Apr '15

1. Go "#(1 2) asOrderedCollection" 2. In the right pane, type "firstIndex" and Go again Either nothing happens or another pane opens on nil. "firstIndex" stays in red, showing that it's not recognized. Is this limitation on purpose? ----- Cheers, Sean -- View this message in context: http://forum.world.st/GT-Inspector-Inst-Vars-Not-Bound-tp4818610.html Sent from the Moose mailing list archive at Nabble.com.

Report about the D4D datathon challenge
by Serge Stinckwich 10 Apr '15

10 Apr '15

Dear all, this is a small report about the RESILIENCE team using Pharo&Roassal for the D4D datathon challenge: http://www.d4d.orange.com/en/home The idea was to use mobile network data from Senegal provided by Orange company in order to solve some development problems. The amount of data provided by Orange was really huge, something like 66 Gb: we have the number and the durations of calls between each pairs of GSM antennas in Senegal (1666 different antennas) and also some information about the mobility of people. You can find more information about the data here: http://arxiv.org/abs/1407.4885 We try to extract some data from August 2013, because we know that some floods occurs at that time in Dakar. Our main objective was to to be able to visualise mobility and communications patterns with ROASSAL to see if there is any differences before and after the floods. We had a lot of problems to solve in a short period of time :-) At the beginning, we couldn't open huge files with Pharo. Only open a file that is around 3.4Go is impossible. Pharo says that the file does not exist. Thierry tells us that us that one must compile the VM with -D_FILE_OFFSET_BITS=64. (the Cog VMs are also built with -D_GNU_SOURCE). Why this is not done by default ? After that we decide to split the files in many smaller files and we try to use a mySQL database and various other tools but still have many troubles because of the size of the data ... At the end, we have done some visualisations but only on a tiny portion of the data on one day (one day is around 100Mb of data). You could find some visualisations done by our team here: https://twitter.com/sergestinckwich/status/586178094215606273 Managing huge amount in Pharo and also ROASSAL is still a challenge and we definitively need more tools in this area. We had some problems with ROASSAL: bugs with RTEdgesBuilder (Alvaro can you send a report to Alex about that ?), to much time to process some viz, ... At the end, our team receive the honorary price: https://twitter.com/sergestinckwich/status/585866625745887232 This is a brief description of our project. ========================================================= Project name: RESILIENCE Team members: Clémence Douard (ENSCI), Onil Goubier (CIRELA), Alvaro Peralta (LabU / Chile University), Aurélie Thouron (ENSCI), Serge Stinckwich (IRD / UMMISCO) The main concern of this project is to improve resilience after an environmental crisis in a southern city. During the preparedness phase before crisis, records of inhabitants habits (like patterns of mobility or communications) are done in order to characterize the situation before the crisis. Assessments of the improvements will then be done by providing suitable visualizations of the resilience dynamic. The goal is to help citizens to represent these improvements and to take advantage of them in their daily lives. We took as an example the city of Dakar during the flooding that occurred in August 2013. The data used are those of the dataset 1 (communication between antennas) and 2 (user mobility) provided Orange. We use this information, coupled to OSM, and other data related to floods of August in Dakar to construct maps and indicators to show resilience. Visualizations are made with agile visualization platform Roassal: http://agilevisualization.com/ ========================================================= I would like to thank all the team members and also the people who help us remotely: Alexandre Bergel (ObjectProfile/Chile University) and Thierry Goubier (CEA) I would like to thank also the SIMPLON team and ORANGE for organizing such a nice event. Regards, -- Serge Stinckwich UCBN & UMI UMMISCO 209 (IRD/UPMC) Every DSL ends up being Smalltalk http://www.doesnotunderstand.org/

new graph algorithms
by Christophe Demarey 10 Apr '15

10 Apr '15

Hi, A few days ago, I added new graph algorithms into MooseAlgos but I did not communicate about that. I added 2 complementary algorithms: - MalGraphReducer : it takes as input a graph and ouputs a graph without circuits. Nodes forming a circuit (or cycle if you prefer) are merged into a single node. A merge node has a reference to merged nodes. It uses the MalTarjan algorithm. - MalTopologicalSorting : the well known graph sorting algorithm that can only be applied on graphs without circuits (cycles). the latter could be useful for some layouting strategies of graphs for example. Regards, Christophe.

text highlighting and selection?
by Alexandre Bergel 10 Apr '15

10 Apr '15

Hi! Apparently something has change recently with selection and text highlight. When I select a portion of text, the highlight goes away in the selected portion. This is a regression apparently. No idea whether this is on moose or on pharo.

Hi! I have just downloaded the last moose and I got an error when I open it. With the “load startup preferences” progress bar interrupted. This may be related to the Spotter tracker?

Force based layout progress bar
by Natalia Tymchuk 08 Apr '15

08 Apr '15

Hello. As we all know Force based layout is quite slow. For example if I use it for more that 200 points it takes ages and during that time I’m not even sure if it works or no. So I wonder maybe it will be better to draw progress bar during the time it works? Thanks. Best regards, Natalia
