Looks like Dennis Ritchie doesn't remember. http://en.wikipedia.org/wiki/Inode ReiserFS isn't universal among Unix/Linux systems. Reiser has been arrested for murdering his wife. http://www.ninareiser.com/ The FS may be at its end. See also http://www.ontrack.com/special/200501-LinuxReiserFS.aspx

If you have a paper audit trail you have clear evidence of all your transactions in your hands. All other arguments are without substance.

It means that code segments that would be in MEMORY has to be offloaded onto slower, more permanent (intended for) storage mediums to be recalled later. The system takes a speed hit with VM, but is permitted to do tasks that would otherwise not be doable. All you have proven is that you know how to use a search engine. |
