FFI Problem with Mac 4.2.5 VM
by Sean P. DeNigris 22 May '11

22 May '11

I'm having trouble calling a Mac Foundation function via FFI. It appears to be the plugin for the Mac 4.2.5 VM. There was a discussion at http://forum.world.st/FFI-to-call-Mac-Carbon-functions-td3507842.html The meat of it is: After I put a link to the Foundation lib in the VM's Resources folder, I compiled: CarbonFunctions class>>NSMakeRectWithX: xFloat y: yFloat w: widthFloat h: hFloat <apicall: void* 'NSMakeRect' (float float float float) module: 'Foundation'> ^self externalCallFailed DoIt: CarbonFunctions NSMakeRectWithX: 0.0 y: 0.0 w: 100.0 h: 100.0. Error: Unable to find function address Other relevant info: * I am able to call libc functions Thanks.

Problems with Mac VM 5.7 and 5.8 on the command-line
by Stefan Marr 19 May '11

19 May '11

Hi Esteban: I have some trouble here with the Mac VM on the command-line. Using 5.7.4.1 like this: /Applications/Squeak\ 5.7.4.1.app/Contents/MacOS/Squeak Pharo-1.2.image results in a file dialog popping up instead of the image. And even worse, when I chose cancel the VM freezes. The behavior on 5.8b12 is identical, but the Cog VM does not freeze on cancel. Using absolute paths (also ~/tmp/pharo/Pharo-1.2.image is ok) works. Ok, so far, that was already my problem yesterday. Really new today is my next issue, headless operation: /Applications/Squeak\ 5.7.4.1.app/Contents/MacOS/Squeak -headless ~/tmp/pharo/Pharo-1.2.image Without -headless it works just fine, with -headless, it pops up a file dialog again. Is that know, or are there any work-arounds/newer VMs I should use?

Re: [Pharo-project] out of memory - cog on windows
by Tudor Girba 18 May '11

18 May '11

Hi, Is there a possibility to have any sort of answer on this topic? It looks to me like this bug is critical given that it prevents us to work with images larger than some 200M. Cheers, Tudor On 16 May 2011, at 11:06, Tudor Girba wrote: > Hi Igor, > > Thanks a lot for looking into this. For us (around Moose), this is a critical issue because we play with our models in memory and regularly have images of several hundred megabytes.

I really don't understand why this doesn't crash
by Torsten Bergmann 18 May '11

18 May '11

>But I guess that should crash. Try to debug using a #halt: (FooClass >> #foo) halt valueWithReceiver: inst arguments: #() This will crash the debugger with an bounds error. Now put an additionall "self halt" into #foo as the first line foo self halt. Transcript show: var5 asString. You will now notice that the debugger works and you can step through. There it jumps from #withArgs:executeMethod: (which is implemented in primitive 188) directly into #foo. You will end up in #foo with inst as receiver and the debugger shows that it was called on AnotherClass but found in FooClass. see the top line of the stack: AnotherClass(FooClass)>>foo But AnotherClass is not a subclass of FooClass so there are more side effects. So I guess primitive 188 does not do any checking and later a random value is returned depending on what is in memory. But I can only guess...

Unfortunately, most users of this technology use it for passive consumption of information and entertainment. To evolve into a true knowledge society it is critical that we transform computer-based human activities to engage users in the active process of creating, connecting, and collaborating together. The C5 conference is for anyone interested in the use of computers as tools to develop and enable user-oriented creation, connection, and collaboration processes. Researchers, developers, educators and users come together at C5 to present new and ongoing work and to discuss future directions for creative computing and multimedia environments. We welcome the submission of theoretical and technical papers, practitioner/experience reports, and papers that bridge the gap between theory and practice or that encourage inter- and cross-disciplinary study. === Keynote Speakers === "Helping Everyone Create with Computing" Dr. Mark Guzdial Georgia Institute of Technology "C2P3: Creating and Controlling Personalisation and Privacy in Pervasive Digital Ecosystems" Dr. Judy Kay University of Sydney === Topics === C5 invites submissions of full papers in (but not limited to) the following areas: - Technology-enhanced human-computer and human-human interaction and collaboration - Virtual worlds and immersive environments - Educational environments for classroom, field work and online/distance learning - New technologies for literature, music and the visual arts - Technologies for collaborative and self-empowered learning - Multimedia authoring environments - Gaming/entertainment platforms, virtual characters, and software infrastructure - Social networks and social networking - Novel programming paradigms and languages for implementors - Scripting or visual paradigms and languages for end-users - Creating and maintaining online communities - Tools for creating/managing online services/environments - Distributed and collaborative working - Social and cultural implications of new technologies Papers should be submitted electronically in PDF format via EasyChair at: https://www.easychair.org/conferences/?conf=c512 Submissions must be written in English (the official language of the conference) and must not exceed eight (8) pages. They should use the IEEE 10-point two-column format, templates for which are available at: http://www.computer.org/portal/web/cscps/home === Proceedings === A preliminary version of the proceedings will be distributed during the conference. The formal version of the proceedings will be published by the Conference Publishing Services (CPS) and sent to authors after the conference. For each accepted paper, at least one of the authors needs to attend the conference and deliver the presentation; otherwise the paper will not be included in the formal proceedings. === Dates === Submission of papers: October 7, 2011 Author notification: November 18, 2011 Camera-ready copy: December 16, 2011 Conference: January 18-20, 2012 http://people.ict.usc.edu/~lane/C5/C5-12-CFP.pdf
