In Linux and UNIX system services are configured using various text files located in /etc/ or /usr/local/etc/ directory tree. A typical server system could have dozens of configuration files.You can check your configuration files for syntax errors without starting the server and validate all settings. In some cases, it is possible to to check the sanity of the specific data (such as keys) or directories (such as /var/lib/cache/). Text files are easier to manage remotely. You can use ssh and a text editor. If there is an error in configuration, the server may not start. It may result in a disaster. This post explains how to quickly find out a syntax error for popular servers and test configuration file for syntax errors.

Excellent article – you can find information about GCC extensions for the C language. 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.
