Monticello Browser -> right click repo -> Edit repository info -> set username & password. Does this help?

Entering login credentials into SmalltalkHub

by Offray Vladimir Luna CÃ¡rdenas

Hi, I took a new image of moose and installed grafoscopio on it with Gofer. This image become my development environment and now I would like to push changes from it to SmalltalkHub, but any time I try, the systems says I'm not logged (which is understandable because I have not identified myself). If I remember quite well the system should ask my credentials, but there is also a way to indicate who I am by code. Any pointers to the solution? Thanks, Offray

At FOSDEM I talked with Bradley Kuhn of the FSF. It is something that has been on their to do list for a while now. In the 'strict' interpretation it is as viral as GPL for smalltalk code. Stephan

Notebook/slideshow morph

by blake

Hey, all-- I've used Squeak successfully in the past to replace PowerPoint (and provide some interactivity in a presentation). Does Pharo have a similar navigable notebook tool like Squeak had? I'm looking for something like a notebook I can add pages to, write some text on, paste some pictures or objects on, etc. ===Blake===
