I want to do mindmaps which are of the quality of mindmeister that you could include picture and links etc and would be able to export it reasonably well and print it.
I love X-Mind. I don't know if it does what you need, but I only use a small subset of it and still it rocks!
It has a very complete free version that never expires and doesn't contain crapware.

I prefer Freeplane but FreeMind can do the same things:

What are three of the basic file operations provided via system calls in the Linux kernel?
I would say the most basic are the four: open(), read(), write() and close().

Hi I am a noob with linux server stuff.
I was wondering if there is a command in linux or there is a way to see which "user" has viewed or accessed a file in linux?
is there a such command?
I thought 'stat' command works could be a possible option, but after googling, I found out that someone posted here at the bottom:
http://www.howtogeek.com/howto/ubuntu/get-last-accessed-file-time-in-ubuntu-linux/
that there is not a way to view 'who' accessed a file. Is this true?
The audit subsystem can tell you who or what has accessed a filesystem object.
