Netscape Friends Activity Sidebar is a Firefox extension that helps you keep tabs on what stories your Netscape friends are submitting, commenting, and voting on. A new toolbar button (shown in the extension preview image) features Chad, the older, more mature brother of AOLs little yellow chat mascot. When there is new activity by your friends (i.e., a new comment, story submission, or vote, depending on your settings), the button will be activated and Chad will send a friendly wave your way. Clicking on the activated button will open a list of your friends activity in the sidebar, allowing you to easily browse their stories and comments. Each time you view your friends activity, you will only be shown activity that is new since the last time you opened the sidebar.

Note: The sidebar limits activity to five items for each friend. If there are more than five items to view, a "View all of Chads activity" link will be shown at the bottom of the friends section. You can always view all of a friends activity by clicking on their name or avatar.

GRUB Disk package contains a GRUB rescue disk.

It consists of a bootable 1.44 floppy image you can use to grab a rescue disk or be run in an i386 emulator, like Bochs.

GNU GRUB is a Multiboot boot loader. It was derived from GRUB,
GRand Unified Bootloader, which was originally designed and implemented by Erich Stefan Boleyn.

Briefly, boot loader is the first software program that runs when a computer starts. It is responsible for loading and transferring control to the operating system kernel software (such as the Hurd or the Linux). The kernel, in turn, initializes the rest of the operating system (e.g. GNU).
