Re: [Pharo-project] Help with a WeakOrderedCollection and objects not being GCed

by Nicolas Cellier

I'm pretty sure the array inst var of your WeakOrderedColleciton is no more a WeakArray but a simple Array. This is because Pharo's WeakOrderedCollection is broken... Every reference to Array from within OrderedCollection should be replaced with message send (self arrayType). See for example, OrderedCollection>>#grow Nicolas 2011/8/3 Mariano Martinez Peck <marianopeck(a)gmail.com>: > Hi guys. I am since yesterday trying to find something and I cannot.

[Pharo-project] ESUG 2011 Innovation Technology Awards: Reminder

by jdelgado

Hi, Again, a reminder: ESUG 2011 Innovation Technology Awards http://esug.org/Conferences/2011/InnovationTechnologyAwards New Deadline: August 15. Have you written innovative Smalltalk? The developers of any Smalltalk-based software can enter by submitting a 3-5min video of their software. Entrants demo their systems in a session at the end of Monday August 22nd 2011, after which the conference attendees vote. (A vote consists in providing a sorted list of 3 preferred pieces of software.) The top 3 teams with the most innovative software will receive, respectively, 500 Euros, 300 Euros and 200 Euros. The results are announced in the Awards ceremony that is held during the social event. Applicants should provide the following information on the conference registration server. Once you have registered your personal info, an "Awards" menu allows submitting your software. You can provide this information when you first register, or login again later and update your details. Info to provide: Name of the software Licence information (free, or shareware, or a commercial) Name of the Smalltalk dialect used Names, Affiliation and Country of developers URL for a video (3-5 min) showing a screencast / demo of the software URL for downloading the software or at least a runnable demo Deadline: August 15 Any Smalltalker can apply (students, companies, ...). The presented piece of code/software should be written in Smalltalk or directly support Smalltalk (e.g. Smalltalk VM). All Smalltalk dialects are accepted. The applicant should own the copyright/copyleft of presented code or at least be the official representative of the copyright/copyleft owner. The software should be available on-line for evaluation (time-limited evaluation version, demo version, free for non-commercial use ...).

[Pharo-project] Setup MacOSX snow leopard server for Pier

by HwaJong Oh

Hi, http://www.appdal.com is my homepage url. Recently, I started Pier server in my MacOSX snow leopard server at url http://appdal.com:8080/ . I want to get rid of the port description 8080 from url by setting a new host assigned to port 8080 like capture image below. http://forum.world.st/file/n3714794/sccc.png Anyone succeeded doing this?

Re: [Pharo-project] Small Seaside image

by Mariano Martinez Peck

Hi Laurent. First, as Marcus said, there is no magic. You should really load the packages of seaside and all the minimal dependes. Just load what you need. Once you are done, evaluate ScriptLoader new cleanUpForRelease. But take a look to what that method does. Then, if you are sure you don't need certain packages from pharo core, thanks to the better modularization we have, you can remove it. Esteban did that for his images for iPhone. There are also some shrink you can do. For example, "To put all all classes with the default category. Still can browse and recompile the whole image. Most production enviroments don't care about categories...this make sense when developing." Smalltalk allClassesAndTraitsDo: [:each | each zapOrganization ]. how much did it help? Fonts. Do you need al fonts? no...remove them. etc...
