Any problem with my mem usage?

[vzhen]

my free -m here.
Mem: used 1838 free 47 what is this?
buffers/cache used 687 free 1198 what is this?

I just open rhythmbox, chromium, IM, stardict, firefox.

vzhen@vzhen-laptop:~$ free -m

It's the second line you want to look at.

687 megs used, and 1198 free.
