I'm currently working in a Mysql driver implementation that will use the C mysql library directly without the intermediation of OpenDBX. That way, the setup of the environment will be far easier and the entry barrier will be lowered. > > > Best Regards! > Rocio. >

Re: [Pharo-dev] Naming of Global Session

+1 Very abstract names are fine when you have namespaces, otherwise I rather chose more specific names. Regards! Esteban A.

I've replaced MessageBrowser and the Finder UI in my own Pharo, and I now have unified menus, shortcuts and smart suggestions and I find it really, really nice.

Startup Preferences

by Goubier Thierry

Hi All, a while ago, I added some settings to one of my projects and it ended up inside my startup preferences, as expected I guess. However, the very next time I rebuilt my image, the first start of the new image displayed errors because of some code inside the startup preferences calling for a non-existent class. Forcing through the errors worked, but then, once fully loaded, that setting was lost. So I looked at the startup preferences code and hacked around a different kind of Setting for my needs, but... has someone else encountered this and found a solution? Thanks, Thierry -- Thierry Goubier CEA list Laboratoire des Fondations des SystÃ¨mes Temps RÃ©el EmbarquÃ©s 91191 Gif sur Yvette Cedex France Phone/Fax: +33 (0) 1 69 08 32 92 / 83 95
