One way is to -bring up the morphic halo (shift-alt on mac) and click until you have the pluggable button selected. -click the debug halo (spanner) and say inspect morph. -see the actionSelector is openRepository -browse implementors, there is only one -correlate this with the model -toggle break on entry in the method view -press the button cheers Mike

Before opening a ticket I would like to check if there is actually a way to specify "automatically detect settings" and a "Use automatic configuration script" as in the windows LAN Settings at all? http://forum.world.st/file/n2237143/LAN_Settings.png ps.

Geert, can you please open a ticket if this is still present? I remember this problem with Alain.

little fix for Slice

by StÃ©phane Ducasse

hi all Does any of you want to help? with a little exercise? It would be nice to help the user to provide coherent slice name I suggest SLICE-number-title title with only alphanumberical-characters any taker? because this would be cool to get another step forward http://code.google.com/p/pharo/issues/detail?id=2478 Stef

[GSoC] Coding started yesterday!

by Mariano Martinez Peck

Hi everybody. First, let me apologize for the multiple cross post. I think it is good to show the Smalltalk community periodically the status of GSoC. The good news in this case is that yesterday the students started to code! This was one of the GSoC deadlines that you can read in http://gsoc2010.esug.org/ and in http://socghop.appspot.com/document/show/gsoc_program/google/gsoc2010/faqs#… . Last two weeks or so, students have been talking and discussing with their mentors, reading and investigating about the projects. Some students already started to code before. But yesterday was the official day to start to code. For those that didn't know, we got not 5 but 6 projects. We asked more and they gave us one more ;) Once again, if you want to look at the 6 selected projects, see http://gsoc2010.esug.org/projects We already told students to ask in case of problems or questions to their mentors but also to the community (trough the mailing list). So, let's help them! Students: don't be shy. Ask! ;) Good luck to all students and enjoy this wonderful opportunity you have. Now we are in the best part of the program! Best regards, Mariano Martinez Peck GSoC admin gsoc-admin(a)esug.org http://gsoc2010.esug.org

PhD thesis potentially in Smalltalk

Hi guys This team has a Phd position which can be done in Smalltalk. Christophe Dony is an old smalltalk fan in the south of france.

Re: [Pharo-users] Debugging "Error: Could not access..."

I am not sure what you are asking? I have the same error when I try to open (to see the packages) any repositories so I assume I have a problem with the proxy server and I wanted to try to figure out why.

Debugging "Error: Could not access..."

I am trying to use the debugger to find our why I get: "Error: Could not access http://www.squeaksource.com/Pharo" via an HTTP proxy server with authentication.
