Notes and experiences on learning embedded Linux systems A typical Desktop Linux system includes three main software layers: Linux kernel, C library, and ApplicationProgramCode. The kernel is the only layer that can fully control the hardware.

You can use the following steps to compile the dynamic library in Linux (assuming that the source file of the dynamic library is named source. CPP, the target file generated by compilation is DeST. o. In the following content, XXX is the name of the

MBR (Master Boot recorder) Stores hard disk information in the Main Boot Sector. MBR is the heaviest hard disk.This is because two important items are recorded in the MBR: The Boot Management Program and the partition table ). Therefore, we are

In recent days, I have made some research on the MTD driver to familiarize myself with Linux driver development. I think some of the articles I can find are not detailed enough, so I wrote some analysis on my own, hoping to help others and make my

Server development requires many considerations, such as the server architecture, stability, performance, and load capacity. In fact, in the process of developing servers, you need to consider a variety of factors, such as servers with short but

Some things will not be forgotten for a long time, so in order not to always find information, simply make a profound note, this can not only deepen the memory, but also deep understanding. Linux servers have not been in touch for a long time. Some

In this experiment, the 64-bit linux3.4.1 source code is modified. Due to some changes in the Code Organization Mode of the new version, some previous methods on the Internet are not feasible. The procedure is as follows: 1. Download the source code

The Linux kernel uses entropy to describe the randomness of data. The greater the entropy, the more chaotic the system is. The computer itself is a predictable system, so it is impossible to use computer algorithms to generate real random numbers.

Zhou haihan/Wen 2010.4.22   When looking at the cluster, I accidentally saw the popular distributed scientific computing SETI @ home a few years ago. The scientific community, such as Berkeley University, was used to calculate astronomical data.
