If you only work with a single server/all servers in the same timezone that translates to: - Do everything in local time or UTC, have one place where you know your zone, - Store all time/date without timezone. - Have in your session timezone information you get from the browser. - Store in the user info their preferred/last used timezone - Translate on the outside Stephan

Voyage: default class to collection mapping
by Torsten Bergmann July 11, 2014

July 11, 2014

Voyage by default provides this: voyageCollectionName "This method can be overridden with a more meaningful collection name" ^ ((self persistentClass name first: 3) allSatisfy: #isUppercase) ifTrue: [ (self persistentClass name allButFirst: 2) asLegalSelector ] ifFalse: [ self persistentClass name asLegalSelector ] So a class name like Association will end up in a mongo collection like "association". But a class name with a prefix like "PDFLetter" will end up in a mongo collection name like "fLetter". Is there a reason for this specific default behavior and not having the class name (by default) as the collection name in mongo? I know I can override the method - but I wonder why it is treated specially also leading to potential conflicts: PDFLetter voyageCollectionName -> #fLetter FLetter voyageCollectionName -> #fLetter Thx T.

FFI on Linux
by Annick Fron July 11, 2014

July 11, 2014

What should be the name of the module in FFI on Linux ? For instance, if there is a shared lib under /usr/lib named gstreamer-1.0 should it be the name of the shared lib or of a module like libgstreamer-1.0.so ? Do I need to put the full path to the lib or is /usr/lib understood by the call ? Annick

Working with timezones
by Esteban A. Maringolo July 11, 2014

July 11, 2014

What is the best way to work across timezones? Today my app assumes a global, shared, timezone for data input, storage, etc. I want to make this configurable, and for that purpose I For what I read and thought about, I understand that the best way to avoid any complication is to store and transfer (between client/server) everything in UTC, and use timezone offset only to convert to/from in order to display the Date and Time. Does anybody have a good article regarding working across timezones? Any tip or suggestion for its use with PostgreSQL and GLORP? Thanks in advance. Esteban A. Maringolo ps: And I guess I now understand the purpose of ZTimestamp :)

How pragma works to create menu?
by Mark Rizun July 10, 2014

July 10, 2014

In the NautilusRefactoring class we have a method on a class side: sourceCodeRefactoringMenu: aBuilder <nautilusGlobalSourceCodeMenu> | target | target := aBuilder model. target selectedClass ifNotNil: [:selectedClass | selectedClass sourceCodeRefactoring: aBuilder ] I'd like to understand how this line works: target := aBuilder model. I mean, how aBuilder initializes a model? Because, if you change the pragma from <nautilusGlobalSourceCodeMenu> to another one, you will get another result using this particular line.

Tide startup
by Max Bareis July 10, 2014

July 10, 2014

Hi, I have installed Tide with the current Pharo 30vm, bower 1.2.6 and node 0.10.29. The installation of Tide was with no error and access to the homepage (in http://localhost:1701/tide/github-cache/tide-framework/tide/master/...) is possible. The page loads but on the javascript console I can see an error within require.min.js line 8 located in tide directory / bower_components/amber/support/requirejs/ I hope this mailing list is the right address to ask if someone else has encountered this and how it could be fixed. Thanks and regards Max

[Blog] PBKDF2 for Pharo
by Udo Schneider July 10, 2014

July 10, 2014

I just extracted some PBKDF2 code from a bigger project. So if you want to derive keys from an non-optimal source (e.g. user input) or store non-reversible passwords with (tunable) secure salting/hashing then PBKDF2 is your friend. The blog is here: http://readthesourceluke.blogspot.de/2014/07/pbkdf2-for-pharo.html The source is on SH: http://smalltalkhub.com/#!/~udos/PBKDF2 Have fun! CU, Udo
