Linux Today just featured a great article on The Cognitive Style of Unix. This is far from the first time someone has pointed out the often steep learning curve required to use UNIX effectively and the huge payoff once you spend the time to learn it. But it’s good to have periodic reminders of the power to the UNIX paradigm – a command line interface and large set of simple tools that rewards complex reasoning, logical thought, and deep understanding with the ability to work efficiently, linking together simple tools to form complex and powerful applications. Contrast this with the Windows and Mac GUI paradigms, which are simpler at first glance and seem to allow more creativity. However, many of the world’s most creative people live in the UNIX world by choice, confirming that the initial learning curve for a system is not always a good indicator of the creative power it grants its users.
