Pharo6 server deployment and no home directory
by Holger Freyther June 18, 2017

June 18, 2017

Hi, as Pharo6 is around the corner I have moved my CI build from tracking Pharo5 to Pharo6 but I run into a problem. Either if $HOME is not set at all or $HOME points to a wrong directory I run into the error below. As this is a server application and I run multiple VMs with the same image and there is no home directory I would prefer that no information is persisted at all. Can this be done? Have there been any changes in Pharo6 in regard to this? It also seems to change from Fuel->Ston for the identifier? Is this intended? holger HOME=/home/blabla ./vm/pharo --nodisplay My.image eval --save '(NonInteractiveTranscript onFileNamed: #stdout)' install PrimitiveFailed: primitive #createDirectory: in UnixStore failed UnixStore(Object)>>primitiveFailed: UnixStore(Object)>>primitiveFailed UnixStore(DiskStore)>>createDirectory: UnixStore(FileSystemStore)>>ensureCreateDirectory: UnixStore(FileSystemStore)>>ensureCreateDirectory: UnixStore(FileSystemStore)>>ensureCreateDirectory: FileSystem>>ensureCreateDirectory: FileReference>>ensureCreateDirectory FileLocator(AbstractFileReference)>>ensureCreateDirectory GlobalIdentifierFuelPersistence(GlobalIdentifierPersistence)>>ensureDirectory GlobalIdentifierFuelPersistence(GlobalIdentifierPersistence)>>save: GlobalIdentifierFuelPersistence(GlobalIdentifierPersistence)>>load: GlobalIdentifierFuelPersistence(GlobalIdentifierPersistence)>>ensure: GlobalIdentifierStonPersistence(GlobalIdentifierPersistence)>>ensure: GlobalIdentifier>>ensure GlobalIdentifier class>>initializeUniqueInstance GlobalIdentifier class>>uniqueInstance SystemSettingsPersistence class>>resumeSystemSettings [ :persistence | persistence resumeSystemSettings ] in PharoCommandLineHandler>>runPreferences in Block: [ :persistence | persistence resumeSystemSettings ...etc...

[Modeling with Pharo] How to model a simple human interaction.
by sergio ruiz June 10, 2017

June 10, 2017

Hey all.. I got my first paying gig that i am able to use pharo with, and i am on the last leg before calling it complete. Hereâs what I need to do.. This application accepts SMS text messages. It allows the user to send images via MMS and place an order to a print house for those images.. Â it then compiles the order, and submits it to the order processing system and makes the prints. The last thing I need to zero in on is handling the interaction. Believe it or not, I have never modeled such an interaction. The interaction goes: - user sends images{s) - bot says âthanksâ and asks if there are more - user types âdoneâ or sends more - on âdoneâ bot asks for print size - bot says âthanksâ and the interaction is done. order is processed. my first inclination is to use a state machine, progressing through order each time the user enters âdoneâ..Â does this sound reasonable, or is there a better model/design pattern for this interaction? Thanks! ---- peace, sergio photographer, journalist, visionary Public Key:Â http://bit.ly/29z9fG0 #BitMessageÂ BM-NBaswViL21xqgg9STRJjaJaUoyiNe2dV http://www.Village-Buzz.com http://www.ThoseOptimizeGuys.com http://www.coffee-black.com http://www.painlessfrugality.com http://www.twitter.com/sergio_101 http://www.facebook.com/sergio101

Epicea vs RB refactorings
by Peter Uhnak May 10, 2017

May 10, 2017

Hi, I'm under the impression that Epicea is supposed to replace RB refactorings at some point. If that is true, is it currently possible to build refactorings by hand? For example in RB I often do: ``` model := RBNamespace new. model defineClass: ('<1s> subclass: #<2s><n><t>instanceVariableNames: <3p><n><t>classVariableNames: ''''<n><t>poolDictionaries: ''''<n><t>category: <4p>' expandMacrosWith: 'Object' with: 'MySomething' with: 'var1 var2' with: 'MyPackage'). cls := model classNamed: #MySomething. cls compile: 'var1 ^ var1' classified: 'accessing'. (ChangesBrowser changes: model changes changes) open ``` or (removing a method from a class) ``` model := RBNamespace new. model removeMethod: #testTrimRight from: StringTest. (ChangesBrowser changes: model changes changes) open ``` Thanks, Peter

using UFFI in non-crashing way
by Peter Uhnak May 7, 2017

May 7, 2017

Hi, is it possible to use UFFI and avoid crashing the image when the called code segfaults? In other words, can I somehow wrap the call and throw in-image Exception/Error on failure instead of the whole thing crashing? Or is the only way to do that have the called thing running as a separate app (e.g. via OSSubProcess) and communicate via pipes or sockets? Thanks, Peter

Voyage - collecting data from Mongo
by Mark Rizun May 2, 2017

May 2, 2017

Hi, Is it possible to retrieve data from Mongo collection if it was not created via Voyage? Meaning that I do not have a class in Pharo that would correspond to said collection (should I implement one?). Cheers, Mark -- View this message in context: http://forum.world.st/Voyage-collecting-data-from-Mongo-tp4944784.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

[Ann] Pharo Sprint App to improve coordination during Pharo Sprints
by Juraj Kubelka May 2, 2017

May 2, 2017

Hi, We are happy to announce a new application called Pharo Sprint App. The main idea of the application comes from the whiteboard that have been used during Pharo Sprints and was also adopted in Chile. As the Pharo Sprint is organized in several places around the world, we miss the connection with other guys. For that reason we decided to move the physical whiteboard to the internet and developed Pharo Sprint App. How does it work? Participants choose a case from the âproposed' or âallâ list. Once they are done, they move it to the âdoneâ list. We believe that the application will encourage other people, especially newcomers, to join us during the events and have a fun, together with other developers. How To Use It? â¢ Download the latest image from Bintray <https://bintray.com/jurajkubelka/PharoSprint/build/_latestVersion#files> â¢ Execute the image, using the corresponding VM for Pharo 6 â¢ Run the application from World Menu / Communication / Pharo Sprint â¢ Login, using your FogBugz account, wait a bit, then choose a case and have a happy programming :-) Everybody participating in the sprints should use the Pharo Sprint image. The upcoming event is on Friday April 28: https://association.pharo.org/event-2492488 <https://association.pharo.org/event-2492488> The application is deployed in Pharo 6 (32 and 64bits). More details are available at: https://github.com/JurajKubelka/PharoSprint <https://github.com/JurajKubelka/PharoSprint> I will appreciate any feedback. Have a fun! :-) Juraj

improving audio/video quality of pharo days recordings
by Peter Uhnak May 1, 2017

May 1, 2017

Hi, we had a small discussion on discord about improving the audio/video quality of recordings of past pharo days, where many recordings are really hard to see (or completely unreadable), or the presenter is really hard to understand (especially if they speak quietly or have a strong accent). Obviously making really good recordings requires several people to focus on it (which is hard on a small meetup), however two things could be imho introduced that could help a lot, with little demand on attendees. 1) clip-on microphone * camera's mic will not capture good sound from 10 meters away over a crowd of people making noises 2) VGA recorder (which goes between the presenter's computer and projector) * then we would have crisp video and not relying on the quality of the camera in fact this is very common format where in the final video you see primarily the VGA output, and not camera capture from a distance (only on the presenter), e.g. https://www.youtube.com/watch?v=XA2WjJbmmoM Unfortunately I am not attending Pharo Days this year (scheduling conflict), so I can't help on-site, but I could help with post-processing where possible, e.g. converting the raw audio/video/VGA streams into one (as in the linked video) or something.
