    In some programming languages you get strange results when counting the number of characters in a non-ASCII string: they’re assuming the string is ASCII and counting the number of bytes it takes in memory. To count the characters accurately the language has to be told what encoding the string uses and it has to know how to parse that encoding.

    Did you know: *nix does not have a file creation time

    The 3 time stamps *nix keeps are:
    1. atime : The last time file was opened or executed
    2. ctime : The time the inode information was updated (chmod, chown etc does that). ctime also gets updated when file is modified
    3. mtime: The time file was closed after it was opened for write

    So all the above stated time stamps change per the usage and hence *nix does not have file creation time

    Command to see mtime #ls -l
    Command to see atime #ls -lu
    Command to see ctime # ls -lc

    Please correct me if I am wrong.

    I am not sure how many of you guys know.

    Did you know:

    Intel stands for 'Integrated Electronics'.
    AMD stands for 'Advanced Micro Devices'.
    Java was 'Project Oak'.
    Microsoft stands for 'Microprocessing software'.
    Word Processor (as in Microsoft Word) does not refer to 'word as in sentence' but, 'word as in size'.
    The word 'Pentium' has its inspiration from hack-culture which used the word 'pentia' to refer number 5 and to imply x586 and trademark a name, they wanted something unique and must also refer to something 'strong', thus, Titanium. Finally, it was: Pentia+Titanium = Pentium. 486 were not pentium
    Name 'Apple Inc' was decided over supper table while biting on apple thus, logo is bitten apple and not full apple.

    Thats all I can think of right now...

    @b0nd:
    Most of the *nix file-systems don't maintain any creation time of files, but however, ext4 filesystem does support all four timestamps: atime, ctime, mtime & crtime.
    You can get the date of file creation time on ext4 filesystems with "debugfs" and "inode number".



    The output of the command "sudo debugfs -R 'stat <2099350>' /dev/sda6 is truncated in the spited window below.

    You can run Firefox inside Firefox

    use the following command in the url box >>

    chrome://browser/content/browser.xul


    P.S: I think maybe we can make a fork bomb like DOS attack from this ..will try some time

    fork bomb i am not sure if that would be coz all windows will be under same process....
    only firefox could be crashed if we open firefox and its home page is set to
    chrome://browser/content/browser.xul
    i hope that should do the trick

    yups .. sorry ... I meant to say that we can crash firefox in the same way as fork bomb does by creating new sessions recursively.
