The only book mentioned in the http://live.gnome.org/GnomeLove page is partly outdated, because it talks about using libgnome and libgnomeui libs, which are deprecated for Topaz… It talks about GMemChunk instead of GSlice, and so on… So selling that kind of book is IMHO not recommended. One of the main problem in GNOME documentation, is that you can’t easily know if it’s up-to-date or not.

[quote]KDE has started an interesting initiative in the area, aiming to produce high quality distance learning paterials for a full QT/KDE course.[quote]

I saw once http://live.gnome.org/GnomeAcademy
All it needs is a person pushing more on this, as Vincent Untz did for Gnome Goals (which seems unfortunately now suspended, as Vincent had less time)…

We also have http://live.gnome.org/MentoredProjects that could grow up if we had a GnomeRecruiter…

Hope this helps, I’ll be at GUADEC, if you want to talk about this… En français bien sûr
