Now we will have a public calendar with the next 6 months of planified events. The calendar will be (may be it is already) added to the web site. Since the team is reorganizing itself and its priority here is a report of our analysis for the first iteration. If you have resources and you want to get an impact please join and let us know.

get the names of the currently loaded mcz files
by Sabine KnÃ¶fel July 14, 2014

July 14, 2014

Hi, how can I get the names of the currently in my image loaded mcz files of a certain package? Example: The name of one of my packages is "RKA24-View". The currently loaded package version is "RKA24-View-SabineKnoefel.390.mcz" ==> I want to call a method with parameter "RKA24-View" and get "RKA24-View-SabineKnoefel.390.mcz" as result.

Re: [Pharo-users] Working with timezones

Esteban wrote: >Anyhow this is too much to add to my app without giving it proper thinking. So let's KISS. 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 :)
