Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

There are cases where I want to change the iptables rapdily and reliably. But these cases don't really change any rule order. They only change just the IP addresses of a rule (or gang of rules).
Here's my idea. Designate some IP addresses for this special purpose, such as 0.1.X.Y where X.Y represents 65536 possible address objects. The address objects are stored in the kernel with a means for root or designated users to access them. There would be a /proc entry for this, with...

I currently use the compiz desktop switcher. It's also what is known as a "compositor", but I really don't know what all the functions are that it needs to perform.

How compiz is working is that is displays some effect on the screen to show how you are doing switching. Some people like the cube effect where when...

I now run many (and soon to be most) of my cron jobs under the screen program. This is easily done by using the screen options "-dmS" followed by the screen session name to use, followed by the command to be run. This will quickly exit, leaving the command running in the disconnected screen session. This seems to work just fine through cron.
You can do this one of two different ways. The simple way is to specify the screen command in the crontab job file directly. Another...
Email is so last century. Sure, many people still use it. I do to communicate with family and friends. But this is really out of place for so much other stuff. It just gets polluted with all the signups people have to do. People are now creating alternate email addresses, usually anonymous, for all these signup sites. This is so the real email, if they even have one, does not get polluted.
