[Pharo-project] [ESUG 2012] Call for sponsors
by Luc Fabresse June 14, 2012

June 14, 2012

Dear Smalltalkers, As you know ESUG (European Smalltalk User Group) is a nonprofit organization, ran by a bunch of volunteers which aims at promoting Smalltalk (http://www.esug.org/Promotion) ESUG does have multiple actions such as sponsoring Smalltalk-related publications (articles and books), encouraging developers and more specifically young students to learn Smalltalk (Student Volunteers program) and build innovative software using Smalltalk (SummerTalk, ESUG Awards, "Support your project" program, Umbrella for GSoC, ...). ESUG revenue comes only from sponsoring, donations, and registrations to the ESUG yearly event (for 20 years!). Therefore, we invite you to support the ESUG actions by encouraging your companies and organizations to sponsor ESUG. As previous years, we have three sponsoring packages ( http://www.esug.org/About/BecomeSponsor) * Silver ESUG Sponsor: By paying â¬ 500 per year, the logo of your company/association is displayed during the ESUG conference, and you are also recognized as a sponsor on our ESUG website http://www.esug.org. You are entitled to mention that you are an ESUG sponsor, and to use the ESUG logo in that context. * Gold ESUG Sponsor: By paying â¬ 1000 per year, you get all of the above, and ESUG correspondence and distributions (CD, Documentation) will feature your logo. You also get a 10% fee reduction on the ESUG events for up to 5 people of your organisation. * Platinum ESUG Sponsor: By Paying â¬ 2000 per year, you get all of the above, but you get a 20% fee reduction on the ESUG events for up to 10 people of your organisation. For any further information, you can contact us directly at board(a)esug.org. Best regards, Luc Fabresse On behalf of the ESUG board

[Pharo-project] New journal paper about Fuel serializer
by Mariano Martinez Peck June 13, 2012

June 13, 2012

Hi guys. If you are interested in learning about Fuel's internals, its differences with other serializers, etc, I invite you to read our journal paper that has just been accepted. This paper is *much* better than the version of the ESUG workshop (in case you have read that one). You can find the pdf here: http://rmod.lille.inria.fr/archives/papers/Dias12a-SPE-Fuel.pdf Fuel website: http://rmod.lille.inria.fr/web/pier/software/Fuel Cheers, -- Mariano http://marianopeck.wordpress.com

[Pharo-project] Zinc: Detect failed binds
by Mark Smith June 13, 2012

June 13, 2012

Hi :), Does anyone know if there's a way to detect if a Zinc Server doesn't bind to a port, (probably because there's already a server listening on that port), and signal an error? Thanks a lot, Mark

[Pharo-project] recompiling class
by S Krish June 13, 2012

June 13, 2012

Can we do this in Pharo: "in Java, the computation of numeric o ffsets for instance elds in memory is done by the run-time system. This permits updating a class with new instance elds or methods without aff ecting existing code. In other words, it is possible to run an existing bytecode fi le for a subclass after updating and recompiling the class, but without recompiling the subclass."

[Pharo-project] FileReference should throw error when deleting unexisting files?
by Mariano Martinez Peck June 13, 2012

June 13, 2012

So if we now do: 'afileThatDoesntExist' asFileReference delete I get a PrimitiveFailed. If this is what we want, can I add: FileReference >> deleteIfExists self exists ifTrue: [ self delete] or something like that? because lots of places (tearDown of tests) I want to remove crao which may or may not exist... thanks -- Mariano http://marianopeck.wordpress.com

[Pharo-project] subclassResponsibility, how does it work?
by Gareth Cox June 12, 2012

June 12, 2012

Hi All I'm attempting to subclass a class (Point) and I want some instructions passed to Point to go to MyPoint. Specifically I have Point >>asMyPoint >> self subclassResponsibility. In MyPoint I've got asMyPoint ^x@y. When I execute code, I get an error that the subclass should have executed... How does this actually work? How should I do this? Kind Regards Dusty
