I got an email from my system administrator saying that I needed to reboot my system to apply some patches. I had forgotten about it and after a couple of hours I got another mail telling me that I was yet to reboot my system.
I have since rebooted my system but I'm surprised how they'd know if I had rebooted my machine or not. Can someone explain how this works?
I'm running the latest version of firefox 17.0.1 on ubuntu 12.10 on a Acer Aspire One 722 Netbook. It has an amd dual core C60 processor and 2GB RAM.
As you can see, firefox is absolutely killing my system, it responds really slowly and opening tabs is a royal pain. I have on an average 4-5 open tabs at a given time. Is there something that I can do to make my browsing experience more zippy?
Additionally I run the following addons
I just got a new acer netbook, it comes with windows 7. I wanted to know how I could create a recovery image using tools like dd.
I want to know what command creates the exact backup of the hard disk and how I could restore it incase things go wrong when I try to install linux.
I have an external hard disk on which I will store this image and a bootable usb drive with ubuntu 12.04. If this isn't the best way then do suggest alternatives.
I have a slow Internet connection and every time I add a new ppa to install software I need to run apt-get update.
This takes about 10 minutes or so, I was wondering if there was a way to initiate a partial update for the newly added ppa's.
My computer shut down suddenly and refuses to boot now. I started it with an Ubuntu Live CD and it reported that a hard disk failure is imminent.
The error reported by SMART:
Reallocated Sector count: The threshold value is 140 but the value is 504.
What does this mean? What should I do next?
I'm backing up all the important data to an external hard disk as I write this.
