setting VM Parameter?
by Yoshiki Ohshima 04 Jan '12

04 Jan '12

Hello, On the latest Cog VM and my image (not so latest), I don't seem to be able to get and set some vm parameters. Specifically, the ones marked as "read-write" in the method comment give me "nil" when queried, and some strange value when try to set. Is this a known issue? And/or, Is there an image side change I should have? Thank you! -- Yoshiki

SOB minutes - 3 Jan.
by Chris Cunnington 04 Jan '12

04 Jan '12

- The bulk of the meeting addressed a sudden change to DNS that has shut down our mailing lists - The problem resulted from the domain squeakfoundation.org which made a change to its DNS configuration 2 Jan. - After the problem is solved, the SOB is resolved to switch over to squeak.org and make squeakfoundation.org redundant to needs - The relationship with the Software Freedom Conservancy was discussed in terms of who is a signatory for the Board. It seems the SFC is the signatory and not SOB memebers - an important bug fix by Colin Putney will be incorporated into the release of Squeak 4.3 - Some final tasks related to the release of Squeak 4.3 were discussed: the creation of an All-In-One release; uploading a zipped version of that and a zipped SqueakCore image to http://ftp.squeak.org /4.3; and then linking from the homepage of squeak.org to that All-In-One app

Category to be ignored by Monticello?
by Dave Mason 04 Jan '12

04 Jan '12

I have some code that generates code on the fly in user classes. I want them to stay in the image for efficiency reasons, but if the user class gets saved in Monticello, I don't want the generated code saved. I can obviously put the methods in some particular category - say *auto*generated*do*not*save*. But after looking at Monticello for a bit, I can't find where it decides what to save - if, for example, it ignores things in other categories. Any help appreciated - either "Yes, it ignores *foo*bar* category", or "Here's where to look in Monticello" Thanks ../Dave

slightly shrunk screen grab?
by Lawson English 04 Jan '12

04 Jan '12

In 4.3, on Mac OS X Snow Leopard running cog, this code: canvas := FormCanvas on: (Form extent: Display extent depth: Display depth). canvas setOrigin: (0@0) clipRect: (-10000 @ -10000 extent: 20000 @ 20000). World fullDrawOn: canvas. canvas form writeJPEGfileNamed: 'screen.jpg'. Produces an image that is slightly smaller than the original squeak World. The screengrab menu produces the same artifact. Its not too big a deal but I was hoping to render the entire desktop into an OpenGL texture and then use it as the ultimate texture demo by making it a live GUI inside of the opengl window, which I had planned to fill the squeak window. It won't be that hard to workaround, but it seems odd that there's a slight discrepancy in the size of the image vs the size of the World morph. L.

Monticello trickery: pointers needed
by Frank Shearar 04 Jan '12

04 Jan '12

Hi, The background to the question is that I'm trying to repackage LanguageBoxes so that both the Squeak and Pharo community can use its features (or just parts of it). Cutie-Helvetia defines a class, CURaisedToExample. Among others, it defines two methods: CURaisedToExample class >> #raise:to and CURaisedToExample >> testSplice. The latter makes use of QQCompiler's splice operation (just like Common Lisp's) - @foo will replace 'foo' with whatever 'foo' evaluates to, so compiling 'a := @(3 + 4)' means the same thing as 'a := 7'. Now testSplice says self assert: `@(self raise: 2 to: -3) = (1/8). which means that, _at_compile_time_, testSplice will invoke #raise:to: (the self refers to the class-side method)... and at this point in time #raise:to: has been compiled, but not installed. Compiling #testSplice fails with a MessageNotUnderstood, and package loading aborts. My question is this: how can I work around this? Can I move the installation of #raise:to: to a preload step? Some hacks that spring to mind, and don't seem very pleasant, are: * introduce a new superclass defining the method, put that in a seperate package, and load that package before Cutie-Helvetia * move the definition of CURaisedToExample and #raise:to: to a separate package, and make all the tests extensions to that package. frank

Call for papers - Science of Computer Programming: Special Issue on "Advances in Dynamic Languages"
by jannik.laval 03 Jan '12

03 Jan '12

================================================ Special issue on "Advances in Dynamic Languages" ================================================ Special issue of Elsevier's Science of Computer Programming (SCICO) Context ------- Over recent years we have seen an increased interest in dynamic programming languages such as Smalltalk, Lisp, Scheme, PHP, JavaScript, Self, Python, Ruby, and so on. These languages have taken a prominent role in teaching, web development, scripting, rapid prototyping, tool building, language engineering, and many other domains. For this special issue we invite high-quality papers that focus on novel research related to dynamic programming languages and applications of these languages. We are interested in research that uses dynamic languages in the context of, but not restricted to: - Aspects, aspect Languages and applications. - Ambient intelligence, ubiquitous / pervasive computing and embedded systems. - Compilation technology, optimization, virtual machines. - Language engineering, extensions. - Model-driven engineering / development. - Meta-modeling, reflection and meta-programming. - Programming in the large; design, architectures and components. - Programming environments, browsers, user interfaces, UI frameworks. - Source-code analysis and manipulation (static analysis,refactoring, type inference, metrics). - Testing, eXtreme Programming / practices. - Web services, internet applications, event-driven programming. - Experience reports. The special issue is associated with the Smalltalks 2011 conference. The Smalltalks series of conferences (www.fast.org.ar) is a lively forum on Smalltalk-based software technologies that brings together more than 200 people from both academia and industry for a period of three days. Submission Guidelines --------------------- Papers should be written in English, in PDF-format and should not exceed 25 pages (including references and figures), using the Elsevier journal format. The LaTeX template for this format can be found at http://www.elsevier.com/wps/find/authorsview.authors/latex Papers must be submitted through the EES submission system located at http://ees.elsevier.com/scico/default.asp When reaching the "Article type" step in the submission process, it is important to select "Special issue: Advances in Dynamic Languages". Each paper will be reviewed by at least 3 experts within the domain. The accepted papers will be published in a special edition of Elsevier's Science of Computer Programming. Papers submitted must not have been previously published (at least 30% new material) and must not be under review for publication elsewhere. Papers must strictly adhere to submission guidelines. If you have questions, please send an e-mail to Jannik Laval (jlaval(a)labri.fr) and Andy Kellens (akellens(a)vub.ac.be). Important dates (tentitavely) ----------------------------- - Submission round 1: March 16, 2012 - Feedback round 1: May 17, 2012 - Submission round 2: June 29, 2012 - Feedback round 2 (final notification): August 17, 2012 - Camera ready version: September 14, 2012 Guest editors ------------- Andy Kellens (Vrije Universiteit Brussel, Belgium) Jannik Laval (LaBRI Bordeaux, France)

We seem to have some problems with the DNS for squeak.org. We're working on trying to figure it out. Box admins - please contact me directly for details.
