Re: what to do on linux?

groups should come up with something to change on

some research and I couldn't find something interesting to do. So I'm
here asking if anyone would have a good suggestion for me.
The /proc filesystem lets you read and write
data in the kernel as if the data were in
files in a filesystem. FUSE does the same
thing for userspace programs.
The Run Time Access library lets you read
and write data in a data structure as if the
data was in a PostgreSQL DB. You can use
RTA to talk to a running userspace programs
this way.
Your project, should you decide to accept,
is to use RTA and a netlink socket to make
the tables and data structures in the kernel
look like tables in a DB.
Might at least be interesting. :)
