Re: [Pharo-users] OSProcess command - non responding image when calling often
Hi Paul, thanks for remark my post! :)
The important here is that David Lewis has confirmed it fix the problem,
http://forum.world.st/OSProcess-error-in-1-3-tp4602389p4607494.html
But I don't know if you guys have here the same problem I had, because the
issue was in Windows (). Just test change ThisOSProcess>>startUp: and see
what happens :)
ThisOSProcess>>startUp: resuming
| aio |
(aio := Smalltalk at: #AioEventHandler)
ifNotNil: [ aio startUp: resuming ].
*OSProcessAccessor initialize.*
self initializeThisOSProcess
HTH
Regards.

Thanks for your details answer. I will review your blog post, I have to learn Roassal too so it's a good way to begin...

Re: [Pharo-users] Panama Papers: a case for reproducible research, data activism and frictionless data (powered by Pharo)
Hi. Looks good :) Just out of curiosity, what data format you used? csv, sqlite? I am interested in using Neo4j from pharo ( http://smalltalkhub.com/#!/~MasashiUmezawa/Neo4reSt) with a large database, and few days ago and found the ICIJ used Neo4j to relate information. In a few days they will give a webinar: http://info.neo4j.com/05262016-ICIJandPanamaPapersOnDemand_Registration.html A question, you can use Neo4reSt to store data and Pharo/Roassal for display on a more or less friendly way? or there is a lot impedance between graph models? 2016-05-20 13:44 GMT-03:00 Offray Vladimir Luna Cárdenas < offray.l...@mutabit.com>: > Hi, > > I'm glad to share my recent work with Pharo/Roassal in the form of a > minisite[1] and a detailed blog entry[2] arguing about interactive > environments for increasing understanding and participation in data > phenomena: > > [1] http://mutabit.com/repos.fossil/panama-papers/doc/tip/index.html > [2] http://mutabit.com/offray/blog/en/entry/panama-papers-1 > > Using a relatively simple visualization I advocate for this case.

Re: [Pharo-users] Voyage: default class to collection mapping
Hi Torsten. May not be the case, but I've seen do that elsewhere (in Pier I think) and the reason is simply remove (sanitize) the namespace of the class (the first two letters in uppercase).
