by Nicolas Cellier 02 Apr '10

Can you pin the world menu ? In my image, the 8 bit depth form cannot be dimmed, see http://bugs.squeak.org/view.php?id=7492 Nicolas

Browser>>openEditString: vs Browser>>buildWith:
by Frank Shearar 02 Apr '10

02 Apr '10

Why does Browser>>openEditString: look almost exactly like Browser>>buildWith: ? It seems like buildWith: could be written like this: buildWidth: builder ^ builder build: (self openEditString: ''). frank

4.1 FTP Directory (link)
by Ken Causey 02 Apr '10

02 Apr '10

I took the liberty of creating a link called 4.1 at http://ftp.squeak.org/4.1/ linked to trunk. When we are close to a release we can convert it to a directory and go from there. I considered calling it 4.1alpha or 4.1beta but although we have been using that directory structure for some years now I wonder if that isn't rather pointless. At best it leaves a broader base directory structure that has to be cleaned up occasionally. Ken

"Did you download the optional content pack ?" Nope, I hadn't thought of that. Now I have lots of avatars. Thanks! Chris

RE: [Pharo-project] Compiling the VM
by Schwab,Wilhelm K 02 Apr '10

02 Apr '10

Interesting! The libpulse part, I mean, in connection with my dlopen() problems. Running Pharo from a terminal (I still think it should log this stuff on its own) captures messages like Inconsistency detected by ld.so: dl-open.c: 643: _dl_open: Assertion `_dl_debug_initialize (0, args.nsid)->r_state == RT_CONSISTENT' failed! and feeding that into Google turns up mention of Skype, library dependcy hassles, and Debian bug 548983. Just grabbing at straws here, but could the problem be caused by the sound library?

dlopen: I'm stumped
by Schwab,Wilhelm K 02 Apr '10

02 Apr '10

Hello all, Attached is my attempt at calling dlopen() from Pharo, and it is not going well. The C code below works as expected, so the problem has to be either in my code or something in Pharo or the VM itself. I am fairly certain that loading the attached is safe, but DynamicLinkingLibrary getProcAddress:'cos' from:'libm.so'. crashes the vm in my experience. Any ideas? Bill /* http://www.unix.com/man-page/All/3/dlopen/ Build as: gcc -rdynamic -o fubar fubar.c -ldl */ #include <stdio.h> #include <stdlib.h> #include <dlfcn.h> int main(int argc, char **argv) { void *handle; double (*cosine)(double); char *error; handle = dlopen("libm.so", RTLD_LAZY); if (!handle) { fprintf(stderr, "%s\n", dlerror()); exit(EXIT_FAILURE); } dlerror(); /* Clear any existing error */ /* Writing: cosine = (double (*)(double)) dlsym(handle, "cos"); would seem more natural, but the C99 standard leaves casting from "void *" to a function pointer undefined. The assignment used below is the POSIX.1-2003 (Technical Corrigendum 1) workaround; see the Rationale for the POSIX specification of dlsym(). */ *(void **) (&cosine) = dlsym(handle, "cos"); if ((error = dlerror()) != NULL) { fprintf(stderr, "%s\n", error); exit(EXIT_FAILURE); } printf("%f\n", (*cosine)(2.0)); dlclose(handle); exit(EXIT_SUCCESS); }

Cobalt VR Meetup follow-up
by Chris Cunnington 02 Apr '10

02 Apr '10

That was pretty fun. I posted a link to the LDAP called Tron Legacy and had people join in the CobaltWorldIntro space. I tried the default CobaltWorld space, but I've added OpenGL code to it and Aik-Siong couldn't join my world. So I switched to CobaltWorldIntro. We tried the audio chat by hitting a button in the lower left of the screen, and at one point we had four people talking while their avatars were standing in a group. My voice, as the host world, sounded choppy, which may be a result of my bandwidth, because other people were connecting to my computer. I have 4768 Kbps down/ and 787 up. (Thank you testmyspeed.com). One problem is that almost everybody was an Alice avatar, which is too the same. There is a menu option to change avatars, but there is only one .mdl file in that directory - Alice. So, I'll need to get some new .mdl files for next time. Also for next time, we probably want to meet at a place that has higher bandwidth than my DSL Basic package from Bell Canada. So that's it for this month. One person said they wanted to do it again sooner, which should be as easy as posting a message on the OpenCobalt Google Group ( http://groups.google.com/group/opencobalt ). Thank you to the people who participated. I look forward to doing it again, and hope to see your avatar again in May. Chris
