Welcome! We believe that you have been looking forward to this chapter for a long time. This chapter covers many topics, such:
Startup Process -- how it works
Bootloader Theory
Develop a simple bootloader
Use NASM to compile this
The program is mainly to capture the vehicle sales information, including the car system, car model, date of purchase, car selling price, driving distance, down payment price and so on information. Words do not say more direct code.Car system py
1. Installation
Redis-py is the Python interface to the Redis Key-value database, installed as follows, and we'll talk about Hiredis this library
Copy Code code as follows:
$ sudo pip install Redis
$ sudo pip install Hiredis
System Environment:
Os:oracle Linux Enterprise 5.6
redis:redis-2.6.8
python:python-2.7.3
Redis Python package version: Redis-2.7.2.tar
Prerequisites:
1. Ensure that the Redis has been successfully installed and properly configured, reference
First of all, this is done purely for fun.
Usually we use Redis mainly to store some data, because the data is in memory, so the query updates quickly. We can also use the PUB/SUB function to implement message publishing/subscription. But today we

1, open the database:Note: Open a database, the filename does not necessarily exist, if this file does not exist, SQLite will be created automatically. The first parameter refers to the file name, and the second parameter is the defined sqlite3 * *
This is the past DOS era of the compilation of source code, although has passed, but for the study of the assembly is still helpful, assembly language is just a basic programmer language, most people can grasp, not necessarily in-depth research.

Here another virus from skism. It ' s a quick overwriting virus but
You can use the source code to write your own viruses.

One, the simplest "operating system"
The simplest "operating system" is the simplest boot sector (boot Sector). Although it does not have any functionality, it can run directly on bare metal without relying on other software. A boot sector is 512

There are many classes related to Array Operations in the system namespace. The system. array class provides the following common methods:Binarysearch: Binary SearchAlgorithmSearch for values in a one-dimensional sorting array.Copy: Copy part of an
The compilation language compiler we used this time was developed by the author of the original book, called NASK. Many syntaxes are very similar to the famous compilation language compiler NASM. Because the author of the original book did not give
SQLite is a database suitable for embedded applications. It is small, fast, and reliable. Real open-source resources are free of charge and do not retain any copyright (PublicDomain ). It does not need to run additional server processes. It is
