Some Unixporn – The Story of My Life Through X Window Managers

my first time was probably with FVWM, it was a standard at that time; then I fell in love with Gnome 1.xx – fresh and elegant; changed it to KDE when Gnome became desktop environment for idiots; after years of development KDE authors finally managed to make me hate KDE for its bloatedness and bugs, … Read more

Cool Linux Stuff: Live Resize of Libvirt Guest’s Disk Served as LVM Logical Volume on SAN Volume

In one of your plug-ins (or create a new empty plug-in for that) add following section to plugin.xml: <extension point=”org.eclipse.emf.ecore.extension_parser”> <parser type=”MY_SEMANTIC_MODEL_FILE_EXTENSION” class=”org.eclipse.gmf.runtime.emf.core.resources.GMFResourceFactory”> </parser> </extension> It will make EMF use GMFResourceFactory for XMI [de]serialization.
