How to change the running process priority
Posted on 7:59 PM by Unknown
The kernel determines which processes require more cpu time than others by the process' nice level, also called niceness. The higher the nice level of a process is, the less CPU time it will take from other processes. Nice levels range from -20 (the least “nice” level) to 19. Negative values can only set by root.Adjusting the nice level is useful when running a non time-critical process that

How to copy VCD in Linux
Posted on 7:22 PM by Unknown

Further, if one copies that video files from windows partition or just tries to play that infamous *.dat video file, Linux does not recognize that file. Of course, if one opens that file with mplayer or vlc (or any other video player) then it does play. Nobody wants to let those good

For example, I have had typical services, such as Apache, appear to start up correctly, but remain inaccessible from the outside world because I forgot to allow the

Why are Linux and Mac OS X safer?
Posted on 10:09 AM by Unknown
First, look at the two factors that cause email viruses and worms to propagate: social engineering, and poorly designed software. Social engineering is the art of conning someone into doing something they shouldn't do, or revealing something that should be kept secret. Virus writers use social engineering to convince people to do stupid things, like open attachments that carry viruses and worms.
