If you want to load a file via the network, just write a local script that does that. If we remove the network support for script parameters, we will directly solve that problem. (and we simplify the whole startup logic, and we make the startup not depend on networking). http://code.google.com/p/pharo/issues/detail?id=4057 Marcus -- Marcus Denker -- http://marcusdenker.de

[Pharo-project] interpreter cannot read image file
by Pavel Krivanek March 28, 2012

March 28, 2012

Hi, I'm trying to open an old production image based on Squeak 3.9.1 file with CogVM and I get: This interpreter (vers. 6505) cannot read image file (vers. 6502) I've always seen only the inverse report. Any idea how to convert the image? Cheers, -- Pavel

[Pharo-project] [GSoC] Call for students
by Janko MivÅ¡ek March 28, 2012

March 28, 2012

Dear Students, Now it is your turn! You will have to register in our website first [1], put there some information, show interest for the projects and contact the project mentors. After the registration step you will get all the mentors information in order to contact them. By pressing the button on the project, you will show your interest. This is not something formal yet. Of course you can propose your own project too. In this case write a proposal in a format other projects have and send it to admins (see the email on the bottom). Our mentors will vote for the most interesting projects and in the middle of the voting Google will tell us, how many projects will actually be funded. Voting will happen in April, with final results expected at the end of April. At that time you will finally know if you are accepted or not. Of course, there can be many students interested per project. This means that interest for this project is high, but on the other side a chance that you will be chosen is lower. It is up to you to convince a mentor that you are the best! Note also that the Ideas page is deprecated. On ideas page just the project ideas were collected. Now, we are preparing the real projects. So, please from now on always refer to this link for the projects: http://gsoc2012.esug.org/projects So, the initial steps are: 1. Register on our special Smalltalk GSoC website (with your Google account!): http://gsoc2012.esug.org/admin?view=loginGoogle 2. Edit your profile to get some more contact information for mentors to let you know, 3. Fulfill your brief Biography page (see Biography tab on profile), 4. Go to Projects page, choose up to three projects and click there 'I'm interested' button, 5. Contact and discuss with project mentors about your interest. Subscribe also to a special mailing list [2] where we will help you with further steps. Deadline: as soon as possible, because the deadline to register on official GSoC website [3] is 6.April, which is, well, soon! But about that later... Finally, we will really appreciate if you can help us to distribute this call for students. One of our goals is to increase the Smalltalk community. Those who have access to universities can distribute this among the students. [1] http://gsoc2012.esug.org [2] Students mailing list: http://groups.google.com/group/smalltalk-gsoc-students [3] Official GSoC website http://www.google-melange.com/gsoc/homepage/google/gsoc2012 Good luck!

Athens is a new rendering canvas that can use Cairo or OpenGL as a backend. http://computeradventures.wordpress.com/2012/03/07/athens-a-first-babysteps/ But of course there is a lot of work to be done...

[Pharo-project] Close encounters of the weird kind
by Schwab,Wilhelm K March 27, 2012

March 27, 2012

Eliot, all, My GSL code, with callbacks is confusing me. First, I call gsl_multifit_fdfsolver_set(). This seems to work, hitting various callbacks (apparently successfully), but then gives an error with #'bad number of arguments'. I have looked, and don't see an invalid number of arguments anywhere. I can proceed past that(??), only to crash in gsl_multiroot_fdfsolver_iterate(). The C backtrace appears below. Is there anything I might glean from it? Any ideas? Bill C stack backtrace: /home/bills/Work2012/Pharo-1.3/CogVM[0x80968b1] /home/bills/Work2012/Pharo-1.3/CogVM[0x8096a52] [0xb7720410] /usr/lib/libgsl.so.0(gsl_multifit_fdfsolver_iterate+0x37)[0x759fc5a7] /home/bills/Work2012/Pharo-1.3/libSqueakFFIPrims.so(primitiveCallout+0x4b2)[0x75c682a2] /home/bills/Work2012/Pharo-1.3/CogVM(interpret+0x3f68)[0x808dcc8] /home/bills/Work2012/Pharo-1.3/CogVM[0x808fc97] /home/bills/Work2012/Pharo-1.3/CogVM[0x8090664] /home/bills/Work2012/Pharo-1.3/CogVM(main+0x38a)[0x809774a] /lib/tls/i686/cmov/libc.so.6(__libc_start_main+0xe6)[0xb7580bd6] /home/bills/Work2012/Pharo-1.3/CogVM[0x805acc1]

Hi guys I'm starting to look at how we can remove SystemChangeNotifier to only use SystemAnnouncement. Now Is there an equivalent to SystemChangeNotifier uniqueInstance doSilently: [â¦â¦] for Announcement? Stef

[Pharo-project] no Complex class in Pharo?

Was this done just for streamlining, or are there known bugs in the implementation of Complex in Squeak? L.
