What is Electromigration?

Under the conditions of high current densities and high temperatures in metals, there is momentum transfer between conducting electrons and diffusing metal atoms. This causes gradual drift of the ions in the metal in the direction of electron flow and result in mass transport. This process of material transfer is […]


Changing the resolution / geometry of a VNC session

You can switch your VNC session screen geometry or resolution on the fly by listing all the possible geometries of the screens you want to use in future while creating vncserver. The syntax for declaring two geometries 1280×768 and 1920×1080 is sam@sun:~$ vncserver -depth 24 -geometry 1280×768 -geometry 1920×1080 You […]
