DynaCASE
by Peter UhnÃ¡k April 3, 2015

April 3, 2015

Hi Serge, I didn't want to hijack the original thread (more than I've already done), so I made a new one instead. Looks really impressive Peter ! > I put some pictures on my twitter account: > https://twitter.com/SergeStinckwich/status/582799867409526784 Thanks! I'll guess I will have to start using twitter now. :) Apparently there is an icon bug when you don't use the Eclipse set of icons. > Yeah, that's my mistake. Thanks for the bugreport. > I'm interested by Petri Nets in order to do Process Mining. > Petri Nets are being developed by my colleague Jan BlizniÄenko ( https://github.com/bliznjan?tab=repositories ) so he may have some more info. I've CCed him. > What kind of process models are you expected to implement ? > Do you plan to draw activity diagrams ? > Right now I'm working on BORM (Business and Object Relation Modeling) http://ccm.fit.cvut.cz/methodologies/borm/ (some of the materials are in Czech, but you can see diagrams in the first link in our current Eclipse-based tool); the following will be DEMO http://ccm.fit.cvut.cz/methodologies/demo/ I can imagine that it wouldn't be that complicated to extend current FSM to have activity diagrams (it's just two extra elements), so if you are interested in that I can look into it. Also I still have to migrate documentation to github so other people can extend it if they want. Thanks! Peter

Non-evaluating and / or
by Jan B. April 3, 2015

April 3, 2015

Hello I would like to ask how to do non-evaluating and. As far as I know, & should be evaluating and and: should be non-evaluating. However, I need to find a way how to use it properly. In "conventional" languages I would expect to work it like in following example... false and: Transcript open Since false is... false... there is no reason to evaluate Transcript open. But when I run this one in playground, transcript opens. Any help is appreciated.

Oracle on Linux
by Norbert Hartl April 3, 2015

April 3, 2015

I see from time to time topics like SQL popping up. Most of the time DBXTalk seems to be a requirement. It is also something that is considered necessary for a lot of people. Now have the need to access an oracle database. Is that possible? And if yes does it also work on linux? Norbert

Voyage performance issue
by Josefina Arcidiacono April 3, 2015

April 3, 2015

Hi! I'm using Voyage with MongoDB. I need to store an object with a large collection. Since both are voyageRoot, there is a Mongo table with all the collection objects and another with the first object pointing to them. With 20,000 objects in the collection it's taking 30 min to save. Â¿Is that normal? Josefina -- View this message in context: http://forum.world.st/Voyage-performance-issue-tp4817087.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

OrderedCollection remove:
by Peter UhnÃ¡k April 3, 2015

April 3, 2015

Hi, I've just run into quite a nasty surprise ~~~~~~~~~~~~~~~~ col := #(1 2 3 4 5) asOrderedCollection. col do: [ :each | col remove: each. ]. col ~~~~~~~~~~~~~~~~ it throws "NotFound: nil not found in OrderedCollection" I tested it also in Pharo3 and there it just silently removed first, third and fifth element. Looking at the implementation of OrderedCollection>>do: it seems that doing what I'm doing is a bad idea. So what shall one do:? col copy do: [...] ? Why can't do: be a bit smarter? Optimization? Thanks, Peter

Writing ConfigurationOf depending on beyond bleeding edge code
by Pierce Ng April 2, 2015

April 2, 2015

I've put up code for JSON-RPC (server only for now, tested with some Python client) on SS3. The code uses Sven's excellent Zinc and NeoJSON libraries. I'm now writing a ConfigurationOf. The current release of NeoJSON, going by its ConfigurationOf, has Neo-JSON-Core-Sven.27. However, I am using Neo-JSON-Core-Sven.29, which has NeoJSONWriter>>writeNil: required by the JSON-RPC spec. How should I express this dependency in JSON-RPC's ConfigurationOf? At present it looks like this (monkey-see monkey-do using some other configuration): spec project: 'NeoJSON' with: [ spec className: 'ConfigurationOfNeoJSON'; loads: #('Core'); repository: ... ] Thanks. Maybe if Sven reads this he can mark .29 as the stable release. That'll work too. :-) Pierce
