best educational experiences..

The best educational experiences are when we work hard for it, when we apply ourselves and think over solutions/possibilities and try to infer things if we are not sure. In college, there were friends with whom we discussed topics, debated possible approaches to problems. Today, I attend interviews! What better ways to know your weaknesses, strengths and different perspectives on technology or implementation!

mount points with space in fstab

Just something i came across recently. I had a space in the filesystem mount point, something like "New Volume" which was a windows filesystem detected and auto-mounted by ubuntu. So how do you add this to fstab? Lookup on the fstab man page says: The second field (fs_file). This field describes the mount point for the filesystem. For swap partitions, this field should be specified as `none'. If the name of the mount point contains spaces these can be escaped as `\040'. Ex: /dev/sda5     /media/New\040Volume     ntfs     defaults     0     2
