Linux kernel 2.2.18 is out at your favorite kernel.org mirror.

The most striking factor about the /proc file system is the fact that the

file system doesn't exist on any particular media. The /proc File System

is a pseudo file system residing in the virtual memory and

maintains highly dynamic data on the state of your operating system. Most

of the information in the /proc file system is updated to match the

current state of the operating system. The contents of the /proc file

system can be read by anyone who has the requisite permissions. However,

certain parts of the /proc file system can be read only by the owner of

IBM claims DB2 Extended Enterprise Edition is the first commercial database for Intel-based Linux clusters. It will be aimed at bio-technology companies and internet businesses that want a cost effective way of expanding databases.

Motor is an integrated IDE that works in the console and provides

the developer with a useful mcedit-like editor, front-end to the

compiler, linker, debugger (gdb), concurrent version system (cvs) and

Geez, can't anyone make money in Open Source? When enthusiasts like

LinuxWorld's Nick Petreley begin to wonder, then you know there's trouble

When you ask most network and system administrators about system and

network security, they'll respond, "We have a firewall" or "We use SSL

encryption." This is all fine and good. However, there are often some things

operating systems have the capability to modify various kernel options while

the system is running.
