UEFI, Secure Boot, Windows 8 and Ubuntu 14.04 - more learnings

One of my recent projects was built around an Intel Atom system. One of its functions was to be a wireless access point. The chip that was in use was an Ralink 8192, hooked up through a USB port.

notes on installing grub on a disk that is not mounted as root

During install fests we sometimes need to install grub on a disk that is currently not mounted on root. For example, if a system can't be booted from its hard drive, but can be booted from a live usb, we want to boot from the live usb and "repair" the hard drive by installing grub on the hard drive.

irssi setup steps:

The configuration file for irssi is found in ~/.irssi/config. It was modified as follows:
