[Pharo-project] ClassBoxes... bitrotted, or usable?
by Frank Shearar June 5, 2012

June 5, 2012

I mused with a colleague about how I'd like to see "lexically scoped monkey patching", and he pointed me to some guys that want to add that to Ruby (http://timelessrepo.com/refinements-in-ruby) Note the inspiration for their work: ClassBoxes! (http://scg.unibe.ch/research/classboxes) I remember reading the paper years ago, and started working through it again now. Something that's not clear to me is this: does ClassBoxes require VM-side changes? (Because it changes the method lookup, after all, searching packages for methods before working up the inheritance tree.) If so, how invasive are they? If not, do we have a ball-park estimate of how much work it would be to update ClassBoxes to a more recent Squeak/Pharo? I'm more than happy to do the dogwork. I'd just like to know whether I'm signing up for months of work or not. Thanks! frank

[Pharo-project] About announcements
by Santiago Bragagnolo June 5, 2012

June 5, 2012

Hi All! Im adding an announcer in my project, 'cause, in order to build a call graph, ill need to know about inferencer-stack movements. I was thinking, the meaning of it is to create an announcement object with it configuration for any push or pop of a stack that's similar to the runtime stack, these are a lots lots lots of objects proably with lesser optimization than BlockClosure. I was thinking in add extension methods that allow me something like self announce: [ StackPush new ] ifAnyIsInteresetedIn: StackPush. Well, i have two questions: a) Am i right? b) subscriptions variable at SubscriptionRegistry is an OrderedCollection, but is commonly accessed to get the subscriptors related with some concrete type, why not a Dictionary? is not faster than an OrderCollection in the tipical case of use? Ok, it could complicate calls like 'remove: subscriptor' but, commonly if you have the subscriptor, you have the Announcement type. Maybe the common ammount of subscriptors in a announcer is too little? Thanks!

[Pharo-project] IWST'12 Call for papers
by Alain Plantec June 5, 2012

June 5, 2012

Dear Smalltalkers, We apologize for multiple reception of this announcement. The International Workshop on Smalltalk Technologies, is a European Smalltalk User Group (ESUG) Conference joint event, that focuses on research activities - namely academic creative work undertaken on smalltalk use, and more generally on object technologies. IWST was launched in 2009, in Brest, during the 17th ESUG Conference. The second edition took place in Barcelona, and the third edition was held in 2011 at the heart of historic Edinburgh. Next edition will be in Gent, Begium this summer (28th of august). ESUG gathers groups of professionals and hobbyists who share an interest in the Smalltalk programming languages and related technologies. The goal of the workshop is to create a forum around advances or experience in Smalltalk. IWST contributes to triggering discussions and exchanges of ideas. As always, we make a point to have a very constructive paper review process that aims to provide in-depth comments and suggestions to all of them (no one-liners!) This makes it ideal to disseminate new research directions, and is a good venue for early stage PhD students to receive feedback on their work. In addition, we intent to invite best papers to a journal special issue as we did last year. Looking forward to your submissions, and to meeting you in Gent! Best regards, LoÃ¯c Lagadec& Alain Plantec Co-chairs of IWST International Workshop on Smalltalk Technologies 2012 August 28th, 2012 Gent, Belgium. ESUG 2012 Smalltalk joint event Important dates Submission deadline: June 15, 2012 Notification deadline: July 15, 2012 All accepted papers will be published in ACM DL, and the authors of the best papers will be invited to submit an extended version to a journal special issue (To Be Confirmed). Goals and scopes The goals of the workshop is to create a forum around advances or experience in Smalltalk and to trigger discussions and exchanges of ideas. Participants are invited to submit research articles. We will not enforce any length restriction. However we expect papers of two kinds: Short position papers describing emerging ideas. Long research papers with deeper description of experiments and of research results. Topics We welcome contributions on all aspects, theoretical as well as practical, of Smalltalk related topics such as: Aspect-oriented programming, Design patterns, Experience reports, Frameworks, Implementation, new dialects or languages implemented in Smalltalk, Interaction with other languages, Meta-programming and Meta-modeling, Tools Links home page:http://www.esug.org/wiki/pier/Conferences/2012/International-Workshop-… submission:http://www.easychair.org/conferences/?conf=iwst2012 Publication Both submissions and final papers must be prepared using the ACM SIGPLAN 10 point format. Templates for Word and LaTeX are available at http://www.acm.org/sigs/sigplan/authorInformation.htm. This site also contains links to useful informations on how to write effective submissions.

[Pharo-project] [ANN] Roassal 1.28
by Alexandre Bergel June 5, 2012

June 5, 2012

Dear Fellow, A couple of weeks ago we have released the Roassal visualization engine. Many of you gave us feedback and we are deeply grateful for this. Since we released the first version, we have closed 25 issues [*]. Many things are left to do, especially to satisfy all the requirements from the Moose community. We are currently working on an HTML exporter for Roassal. We know this is a highly wanted feature. In a couple of weeks we should be able to deliver it. Since the first release of Roassal, we have worked very hard on it and we will continue to do so. Thanks to all of you! Alexandre, Vanessa, Juan Pablo [*] http://code.google.com/p/objectprofile/issues/list?can=1&q=status=Fixed%20c… -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

[Pharo-project] idle VM runs at constant 3-5% CPU load
by Igor Stasenko June 5, 2012

June 5, 2012

i just wonder, what takes so much CPU time, even if it completely idle... 4831- NBCog 4.8 51519- NBCog 3.5 if i kill a UI process, the load goes down to 2.5-3 % ... still too much. i would like to know how we can minimize this. The reason why i concerned is straightly pragmatic: extending battery life.. i found that if i run completely on battery.. it depleting quite fast with VM running (and i don't do anything just coding, i.e not running benchmarks, but more thinking and typing). -- Best regards, Igor Stasenko.
