Gnome Panel

One of the advantages of using GNU/Linux operating system is that you hardly have to restart it. I have Debian on my laptop and it’s been running for months, until last night. It crashed and froze. Anyway, that’s not the main point this post was written. After restarting, I saw this new icon in the Gnome top panel (the third icon from the right): Well, for the start, I don’t know what it is and I don’t think I will have a need for it either....
