1. Kernel functions map Low-dimensional space to high-dimensional space The following chart is located in the first to second quadrant. We pay attention to the red door and the purple letters under the words "Beijing courtyard". We think of the dots on the red Door as "+" data, and the dots on the purple letters as "-" data, and their horizontal and vertical coordinates are two characters. Obviously, in this two-dimensional space, the "+" "-" two typ

It was just a day, and I studied how to compile Linux kernel in my spare time. I used to work on Windows platforms and almost never used Linux, so I wanted to have a good time. The platform is the latest Ubuntu 10.04 LTS, and the kernel is also the latest version 2.6.35.2 downloaded. In fact, kernel compilation is much more convenient than in the past. If menucon
