  4. Hi Prashanth,

    Great piece on Three Layers of RPD, I’m a fan of the ‘flowery’ style Looking forward to more long form articles ??

    The only time a consistency check occurs using ext3 is in certain rare hardware failure cases, such as hard drive failures. The time to recover an ext3 file system after an unclean system shutdown does not depend on the size of the file system or the number of files; rather, it depends on the size of the journal used to maintain consistency.

    I'm fairly new to Linux, and am, having a hard time retrieving the "remote access", on Linux. I'm unfortunately, spoiled by Windows, and have all but completely forgot DOS...Cmds.... Help!!!
    But great job man, do keep posted with the new updates.

    Thank you,
    Kevin
