I had this trouble with Squeak. It transpired that Squeak has a recycle bin! I changed a preference and all my junk objects disappeared.

Hi, a fairly long report on the image and memory hogs is : SmalltalkImage current reportCPUandRAM Writes files in the image folder containing all the information. Takes a while to run.

You might want to inspect this to see if this gets you something interesting. (Object allSubclasses collect: [ :aClass | aClass -> aClass allInstances size]) sort: [ :a :b | a value > b value ] It takes some time to run, especially in a larger image. Stephan

Personally I never got a 200MB image size, you have very likely persisted large collection of objects of your own in your image.

I've tried, at some degree, all of your suggestions, but i failed to reduce the image size significantly. I'll keep trying, meantime i've started with a fresh image. Thank you for your answers.

Relationship between Morph and Canvas

by nacho

Hi, I've been digging and inspecting all the classes related to Morphic. But there's something that I don't happen to figure out. Morph has a method drawOn: aCanvas aCanvas fillRectangle: self bounds fillStyle: self fillStyle borderStyle: self borderStyle Which if it's not overridden by a subclass of Morph makes it possible to still instantiate a Morph -the classic blue rectangle. Now aCanvas is obviously an instance of FormCanvas or some other subclasses of Canvas. But the question is, where does Morph create such instance of FormCanvas? How does this work? I'm getting all wrong? I read the documentation available but I can't grasp it from what I have read. Thanks in advance for your help best Nacho ----- Nacho Smalltalker apprentice.

CFP - IWST 2015

by jannik laval

[Please accept our apologies if you receive multiple copies of this call] [Please send to interested colleagues / mailing-lists] ************************************************************************************************************ CALL FOR PAPERS IWST15 â International Workshop on Smalltalk Technologies Brescia, Italy; July 15, 2015 http://www.esug.org/wiki/pier/Conferences/2015/International-Workshop-IWST_… ************************************************************************************************************ ------------------- 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. The topics of your paper can be on all aspect of Smalltalk, theoretical as well as practical. Participants are invited to submit research articles or industrial papers. This year we want to open two different tracks: one research track and one industrial track with less scientific constraints. We expect papers of three kinds: Short position papers describing emerging ideas Long research papers with deeper description of experiments and of research results. Industrial papers with presentation of real and innovative Smalltalk applications; this kind of paper should enlighten why Smalltalk is really appropriate for your application. We will not enforce any length restriction. -------------------- Important Dates -------------------- Submission deadline: April 10th, 2015 Notification deadline: May 20th, 2015 Workshop : July 15th, 2015 All accepted papers will be published in ACM DL (To be confirmed) ------------------- 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 ------------------- Best Paper Award ------------------- To encourage the submission of high-quality papers, the IWST organizing committee is very proud to announce a Best Paper Award for this edition of IWST. We thank the Lam Research Corporation for its financial contribution which makes it possible for prizes for the three best papers: 1000 USD for first place, 600 USD for second place and 400 USD for third place. The ranking will be decided by the program committee during the review process. The awards will be given during the ESUG conference social event. The Best Paper Award will take place only with a minimum of six submissions. Notice also that to be illegible, a paper must be presented at the workshop by one of the author and that the presenting author must be registered at the ESUG conference. ------------------- 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. ------------------- Submission ------------------- All submissions must be sent via easychair: https://easychair.org/conferences/?conf=iwst2015 ------------------- Program chairs ------------------- Anne Etien (UniversitÃ© de Lille 1, France) Jannik Laval (Ecole des Mines de Douai, France) -- ~~Jannik Laval~~ Ãcole des Mines de Douai Enseignant-chercheur http://www.jannik-laval.eu http://www.phratch.com http://www.approchealpes.info http://car.mines-douai.fr/
