I try to automate almost all things in order to save time. Inexperienced sys admin and help desk staff working under me finds all these tools useful. It saves their time and avoids security issues. Automation allows help desk staff to do things that they don't have enough direct system knowledge to do themselves. However, selecting correct tool and applying correct methodology is very important.

The Linux kernel uses several special capabilities of the GNU Compiler Collection (GCC) suite. These capabilities range from giving you shortcuts and simplifications to providing the compiler with hints for optimization.

This article provides a glimpse of the techniques made available by GCC in the Linux kernel. You can read more about all the available extensions for both C and C++ in the GNU GCC manual.]]> http://www.cyberciti.biz/tips/gcc-hacks-in-the-linux-kernel.html/feed 0 Why Does The Segmentation Fault Occur on Linux / UNIX Systems?http://www.cyberciti.biz/tips/segmentation-fault-on-linux-unix.html http://www.cyberciti.biz/tips/segmentation-fault-on-linux-unix.html#comments Fri, 12 Sep 2008 05:52:41 +0000 nixCraft http://www.cyberciti.biz/tips/?p=2891 An error in which a running program attempts to access memory not allocated to it and core dumps with a segmentation violation error.
