    Question Memory Optimization

    I found this website http://it.toolbox.com/blogs/locutus/...ry-usage-23461 which suggests using the command

    echo -e "\0101\0160\0162\0151\0154\0040\0106\0157\0157\015 4\0163\0041"

    to increase memory performance and I have several questions:

    1. Is this a legitimate hack?
    2. Does this apply or do any good in Karmic or is it already in place?
    3. How could I reverse this if I break something?


    I've been using Ubuntu for over a year but stick mostly with the gui having a limited understanding of the command line. I'm running 9.10, ext4, 64-bit. See the first part of my sig if you have any questions about my hardware.

    Re: Memory Optimization

    According to the writer's comments at the bottom of the article, the command is supposed to be a toggle switch, so executing it a second time reverts to the old behaviour.

    Can no one write anything legitimate on April Fool's? And yes, I did notice the date (it's old and we are now in the age of Karmic). Being a newb, I have not the faintest understanding of the bash line. The reason I brought it to this forum was to get a more experienced perspective before I hose my system.

    Re: Memory Optimization

    If you look at the manpage of echo (man echo) you will see the following:
    "-e enable interpretation of backslash escapes"
    and
    "\0NNN the character whose ASCII code is NNN (octal)"

    I can't translate ASCII but maybe you find the following table helpfull:

    Run the command. It won't hurt your system, and you'll also realise how childish we all are

    Re: Memory Optimization

    I didn't tried it but thought something like that. Would be a new way of fun for something like "sudo rm -rf"
