The Linux kernel config system, Kconfig, uses a macro language very similar to the make build tool's macro language. There are a few differences, however. And of course, make is designed as a general-purpose build tool while Kconfig is Linux-kernel-specific. But, why would the kernel developers create a whole new macro language so closely resembling that of an existing general-purpose tool?

In any programming language, idioms may be used that may not seem obvious from reading the manual. Often these usages of the language represent ways to make your code more compact (as in requiring fewer lines of code). Of course, some will eschew these idioms believing they represent bad style. Style, of course, is in the eyes of beholder, and this article is not intended as an exercise in defining good or bad style. So for those who may be tempted to comment on the grounds of style I would (re)direct your attention to /dev/null.

Grepping is awesome, as long as you don't glob it up! This article covers some grep and regex basics. There are generally two types of coffee drinkers. The first type buys a can of pre-ground beans and uses the included scoop to make their automatic drip coffee in the morning.

Text searching is a bit like that.

Software has permeated all industries, bringing us technologies to help create fantastic products and even works of art.No longer confined to sectors whose products are software-focused, everyone from the automotive to the medical industries are writing their own code to meet their needs, some of which may surprise you.

It's great to treat your infrastructure like cattle—until it comes to troubleshooting.

Few journeys in the world of open source have been as exciting as Mozilla's. Its birth was dramatic. Netscape, the pioneering company whose Netscape Navigator browser shaped the early Web, had enjoyed the most successful IPO up until then, valuing the 18-month-year-old company at nearly $3 billion. That was in 1995. Three years later, the company was in freefall, as the browser wars took their toll, and Microsoft continued to gain market share with its Internet Explorer, launched alongside Windows 95. Netscape's response was bold and unprecedented. On January 27, 1998, it announced that it was making the source code for the next generation of its web browser freely available under a GPL-like license.
