Changing Background GWorkspace

GWorkspace application in GNUstep, is like the equivalent to Nautilus under GNOME. It has interesting features that I'm beginning to love, right now I believe GNUstep is for UNIX-geek-old-fashioned. Here is the screenshot for changing the background image, you need to go to Info->Preferences->Desktop (drop down) then click Choose button for search the image. I'm running GNUstep compiled in Ubuntu 10.04 and the image comes from the folder / usr/share/backgrounds/ Another really cute functionality of GWorkspace is start applications from their installation folder, you need to open the viewer from menu View->Viewer and go to the installation application folder (in my case compiled from sources: /usr/local/lib/GNUstep/Applications ) then a double-click starts the application (*.app)

Gnome-Software en Fedora 21

Fedora 21 es mi escritorio ahora. GNOME 3.14 es mas sexy que Unity, la interfaz es simple y funcional. Instalando Programas Fedora supone un cambio en el manejo de instalación de paquetes yum ha sido la herramienta desde la terminal de comandos; en general es fácil de usar y puedes acostumbrarte rápidamente a usarlo como apt-get de debian/ubuntu. Yum a su vez será reemplazado con DNF y prácticamente los comandos son los mismos. Gnome-Software gnome-software es el programa para instalar desde una interfaz gráfica, es sencillo con una presentación bastante limpia. Sin embargo un día dejó de presentar los programas mostrando solamente las opciones vacías. Intentando revisar en fuentes de software simplemente salía un mensaje con la leyenda fuentes no encontradas o vacías...
