Like most sys admin, I’m lazy. 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.

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.

Posted on in Categories C Programming, Download of the day, FreeBSD, Linux, UNIX last updated March 27, 2008

The Art of Unix Programming by Eric Raymond is a book about the history and culture of Unix programming from its earliest days in 1969 to now, covering both genetic derivations such as BSD and conceptual ones such as Linux.

You should read this book if you are an experienced Unix programmer who is often in the position of either educating novice programmers or debating partisans of other operating systems, and you find it hard to articulate the benefits of the Unix approach.

You should read this book if you are a C, C++, or Java programmer with experience on other operating systems and you are about to start a Unix-based project.

You should read this book if you are a Unix user with novice-level up to middle-level skills in the operating system, but little development experience, and want to learn how to design software effectively under Unix.

You can read HTML version of “The Art of Unix Programming” online at Eric’s website.
