Debian Kernel Compile instructions
Compiling a linux kernel is not an easy job if you don’t know what you are doing and most of the articles and tutorials out there don’t really make sense to me. I found a Debian kernel compile how-to by Falko Timme which does a really good job of explaining what to do and how to do it.

Building an Infrared Transmitter
Several motherboards have the necessary hardware for the installation of an infrared transmitter/receiver, requiring only the installation of a module containing the infrared sensor. The great problem, however, is that this module is not easily found in the market and, when it is, its price is high. Our friend Alain Gailland created this module and any user who knows how to use a solder iron can assemble it.

How to log idle users out of a Linux system?
Idle users are a big problem if the system doesn’t either log them out or lock the session. This is so because if a session is idle that means it might be unattended and could be used by an unauthorized person to gain access to restricted resources.
In windows idle the OS can be instructed to lock accounts after a specific idle time and in KDE/Gnome the screensaver’s allow us to the same thing. But this doesn’t cover the shell access. Users can remain logged in indefinetly unless they logout. Below are some programs that will log a user out if they exceed the specified idle time:
- Set TMOUT= in /etc/profile. (Only for bash, sh users)
- Use timeoutd
- Use porttime to control login times.
If you know of any other ways please let me know.
