Hi, there will be a Small Harbour (http://smallharbour.org - a public fork of SeasideHosting codebase) on Tuesday 2 August, from 11h to 18h (Paris time). You can participate using Skype and TeamViewer. If you can come "for real", Romain and I will be at the Gallice CafÃ© (http://www.gallicecafe.com/) Cran-Gevrier (France, near Annecy). Actually the main goal is to setup the first public server for alpha testers Other goals: - add the possibility to create an account and deploy a template pier image in one click - nice theme - code cleaning - some VM stuff Send me email if you want to participate.

[Pharo-project] add: message declared in Collection
by dimacamp July 31, 2011

July 31, 2011

Does anyone know why the #add: message is declared in Collection as subclassResponsibility if then some subclasses need to cancel the message raising a shouldNotImplement exception? Why isn't just declared in the classes that really should answer that message? Thanks.

[Pharo-project] Configuration Browser is a mastery
by Lukas Renggli July 30, 2011

I played earlier with the "Configuration Browser" and wondered what it was all about ... After the following question on StackOverflow I played with it again: http://stackoverflow.com/questions/6880596/how-to-browse-metacello-reposito… Maybe it should be removed from Pharo 1.3, if the following issues cannot be fixed easily? 1. The windows is empty, refreshing leaves the window empty. This seems to be because <http://www.squeaksource.com/MetaRepoForPharo13> is an empty repository. It would probably be better to point it to <http://www.squeaksource.com/MetacelloRepository> which seems to be the repository with most configurations; or fill the other repository with some tested configurations? 2. The listing lists many packages that are clearly not configurations, e.g. Bogus-cwp.18, Illiad-Core0.1, ... Loading them opens a debugger. 3. The tool doesn't show me what configurations are already loaded (ok, that might not be implemented yet, but would be a key feature and easy to find out). 4. MetacelloConfigurationBrowser>>#refresh and MetacelloConfigurationBrowser>>#loadConfigurationWithLatest: duplicates the manual parsing of package filenames. This is bound to break. Why not use Gofer?

[Pharo-project] CameraPlugin for VM
by Torsten Bergmann July 29, 2011

July 29, 2011

Hi VM developers (CC Squeak and Pharo list), anyone know about the state of integrating the camera plugin from scratch into the Squeak VM sources. Last discussion I know of is at: http://forum.world.st/Camera-plugins-was-Re-Video-Media-in-Squeak-td2020502… Any news on this or any progress? Are there plans to integrate the plugin into Cog as well? Thx Torsten -- NEU: FreePhone - 0ct/min Handyspartarif mit Geld-zurÃ¼ck-Garantie! Jetzt informieren: http://www.gmx.net/de/go/freephone

Yes, I managed to make it work last year, just with the *.cs and the Win32 DLL from scratch. However feel free to post a short guide for the recent Pharo image to the list so others can profit from it. My post was more oriented towards the VM developers since AFAIK there was a discussion of integrating the plugin back into Squeak VM sources so it is available in general to Squeak/Etoys/forks. As Bert wrote: "but the Scratch folks are interested in having their plugins in the main Squeak VM, so they do not have to package and maintain them themselves for ever." Would be nice if one would be able to use the cam out of the box with a recent VM (standard and cog) and Pharo. Thx Torsten -- NEU: FreePhone - 0ct/min Handyspartarif mit Geld-zurÃ¼ck-Garantie!
