[Pharo-project] Call for Participation Smalltalk Directions
by StÃ©phane Ducasse Dec. 5, 2011

Dec. 5, 2011

Hi guys I encourage you to send article to Smalltalk Directions Stef 19thâ21st March 2012, Biloxi, Mississippi Smalltalk Directions is a refereed symposium that will be co-located with the Smalltalk Industry Conference (STIC) in March 2012. The Smalltalk Directions Symposium will run in parallel with STIC, offering a parallel track of presentations of refereed academic work that will be open to all attendees of STIC. We solicit research papers concerned with the future of the Smalltalk language, forward-looking applications of Smalltalk and Smalltalk-inspired languages, and the core technologies supporting such languages, including but not limited to: 1. Libraries & Frameworks 2. Language extensions and contractions 3. Implementation technologies, such as Virtual machines, compilers, instruction sets, garbage collection 4. Object persistence 5. Distributed objects 6. Program development tools and environments 7. Using Smalltalk to educate future object-oriented programmers 8. Design Patterns in and for Smalltalk 9. Modelling 10. Meta-programming 11. Domain-specific languages implemented in Smalltalk 12. Smalltalk on the web 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 information on how to write effective submissions. We are working to have accepted papers appear in the ACM Digital library. A special issue of the Journal of Object Technology will be published in conjunction with the symposium. The authors of selected papers will be invited to submit an extended version of their Smalltalk Directions submission to this special issue, which will then conduct its own reviewing precess. Papers must be submitted electronically using EasyChair (https://www.easychair.org/conferences/?conf=smalltalkdirections2) Important Dates Paper submission deadline 6th January 2012 Author notification 4th February 2012 Final version deadline 24th February 2012 Symposium 19thâ 21st March 2012 Organizing Committee Andrew P Black Portland State University, USA black(a)cs.pdx.edu Ralph Johnson University of Illinois, Urbana-Champaign, USA rjohnson(a)illinois.edu Roger Whitney San Diego State University whitney(a)cs.sdsu.edu David West New Mexico Highlands University dmwest(a)nmhu.edu

[Pharo-project] OBPane coordinates
by Sean P. DeNigris Dec. 4, 2011

Dec. 4, 2011

Am I hallucinating, or do the OB morph classes use local coordinates e.g. #center reports the distance from the topLeft, which reports 0@0? If this is really happening right now, why is this, and how do I get their global coordinates? Thanks.

Re: [Pharo-project] VM freezes sending #basicNew to Stream subclass
by Marcus Denker Dec. 4, 2011

Dec. 4, 2011

Hi, We had a look and the problem is that printOn: on Stream is defined to print the contents of the Stream even though it might not be initialized yet (e.g. when creating a Stream instance with #basicNew). The simplest solution is to just not print the contents of Streams in #printOn: http://code.google.com/p/pharo/issues/detail?id=5047 Stream should not print its contents in printOn: Reason: => Debugging leads to change the state of Stream when looking at it => Network streams load all content => unitialized Streams has undefined behavior for printing Solution: remove #printOn: On Fri, Dec 2, 2011 at 9:08 AM, StÃ©phane Ducasse <stephane.ducasse(a)inria.fr> wrote: >>>> >>>> I only had a look in Pharo 1.4 >>>> It sounds like a subtle bug related to introduction of >>>> SubclassResponsibility in Pharo. >>>> If you revert Object>>subclassResponsibility to its previous version >>>> you get a more reliable error. >>> >>> What would be your hypothesis?
