    Removing and creating files on UNIX/Linux and using the shred command. 

    The shred command on Linux is the perfect way to remove files securely from your Linux system. With a large amount of iterations, it will ensure that it is very difficult to get the data back. the -u parameter will delete the file after the overwriting process.

    [email protected]:~$ shred -n 20 -u gegl-0.2.0.tar.bz2

    To create a file on Linux, the touch command may be used. if you type touch myfile.txt it will create an empty file that you may then fill with text. Or this command: echo “” > myfile.txt. below is the most hackish way to create an empty file that you may then fill with text. Reading from /dev/null for once…

    [email protected]:~/Desktop$ dd if=/dev/null bs=1 of=myfile.txt
    0+0 records in
    0+0 records out
    0 bytes (0 B) copied, 1.2069e-05 s, 0.0 kB/s
    [email protected]:~/Desktop$ ls myfile.txt 
    -rw-r--r-- 1 neo neo 0  12-04-12 09:15 pm myfile.txt

    That is why Linux is so cool, the fact that everything under /proc and /dev is a file and can be manipulated as a file can. That is one of the main strengths of a UNIX and Linux operating system. And the Macintosh operating system as well, because that runs on top of the Darwin UNIX OS.

    Of course the rm command on UNIX/Linux is easy to use, the rm –no-preserve-root -rf / command is famous for being the one command you do not want to execute as the root user. But the rm -f command is perfect for removing files. Just be cautious when using the rm -rf command and double check the command you have typed and use the pwd command to see where you are before executing it.

    Gnome Shell whining and our journey into idiocracy. 

    The Windows 2505 interface?

    The Windows 2505 interface?

    The Gnome Shell desktop is still getting flak after all this time, the tablet interface is not suited to the desktop at all. But if you do not like the desktop install another one and then you will be happier. The constant whining about whether the Linux desktop is going downhill is grating. At least we do not have an Idiocracy styled Metro desktop that is far too childish looking for my liking. I hope the KDE desktop does not adopt such an ugly Fisher-Price interface design that is going to backfire on Microsoft severely. If they adopt the Metro interface solely for Windows 9, then it will truly a sign that Idiocracy has come true; the education system in the Homeland is already heading this way, I have heard of a case where a school was penalized for having a book on grammar! WTF? And with the brainless television shows that most of the people watch such as American Idol and Jersey Shore. Even the news is only a couple of minutes of real news and the rest is mindless entertainment news about the Kardashians or the latest exploits of the drug addicted television stars assault charges. Heaven Forbid that people would ever read a book and learn something about the world at large. Like the old joke about the Americans that think that Europe is a country. Sure, they have a unified currency the Euro, but they are still separate countries. The retarded television shows like CSI do not help, with their magical technology and tera-pixel cameras that can zoom in on a single screw holding on a license plate and then see a persons face in the reflection. Then they can use facial recognition technology to identify the person.

    That is quite fanciful considering the resolution of real security cameras. Terapixel cameras would cost billions and would not be used as basic security infrastructure, that does not make sense. Do you want to watch what is passing through your eth0 port whilst you are browsing the Internet or performing other network tasks? The below command will perform this task. Simply run this command in an xterm and then open a browser window and the whole process of loading a web page will be revealed.

    sudo tcpdump
    Idiocracy television display. We are not far from this future.

    Idiocracy television display. We are not far from this future.

    Very cool to watch too. More interesting than watching reality television. People watch too much of that and are dumbed down by it and everywhere there are the signs of this happening. The movie Idiocracy was a very prescient film with the giant television screen taken up with giant advertisements and a small space in the center for the actual television show. With the violent TV that is on at the moment it will not be long until we have a real version of Ow my balls! The violence channel will come into being soon and then our descent into the nadir of human civilization will be complete. the Jersey Shore has characters with ridiculous nick-names that is just as retarded as the characters in the Idiocracy movie. And of course Jackass and all of those other retarded television shows are paralleling the Ow my balls television show pretty well. And the Funniest Home Videos show that makes fun of babies, adults and elderly people injuring themselves in hilarious ways. We just need President Comacho and our journey will be complete. I agree with the poster on the linked page, it is no wonder that many people hate America, it is truly the dumbest country in the world. Actually, the Funniest Home Videos show is tied for the most similar show to Ow my balls. it is truly dumbed down television and is not a credit to any country to have created this show. Maybe it would not be a bad thing if a giant super-volcano blew up California. if a giant Yellowstone volcano opened up under the Jersey Shore and melted everyone, it would be doing the world a favor.
