5. MPEG audio tags MPEG audio tags can be divided into two types: ID3v1, which has a file tail and a length of 128 bytes, and ID3v2, which is an extension of ID3v1 and has a file header with an indefinite length. 1. ID3v1 The ID3v1 label is used to

1 IntroductionThe time display function of the desktop Windows system is well known and implemented by the BIOS clock module. You can click the time in the lower-right corner of the taskbar of the desktop system to modify the current time and time

There is a friend in a storage space for ASM use, there is insufficient space, and then use another storage LUN to the ASM Data Disk group to increase ASM disk, run for about 1 days after the ASM disk group directly dismount, Database crash. And

Grub Source Analysis-1 This chapter begins the analysis of Grub's source code, version 2.02. When the system starts, the BIOS loads the first sector of the hard drive (assuming boot from the hard disk) into the memory 0x7c00 location, which

Research on STM32 independent watchdog IWDG and window watchdog WWDG Daniellee_ustb 2014-9-25 1. Watchdog introduction The watchdog thing is simple, but I believe most programmers don't pay enough attention to it. It is necessary to use the watchdog

For the WWDG routines given by the STM32 window watchdog and the atomic battleship, there are a few issues to be recorded. 1. WWDG time-out formula derivation 1.1 WWDG work diagram 1.2 WWDG time-out formula derivation (1) The value of the upper

This article is my recent Node.js learning process of an idea, put forward to discuss with you. HTTP Server for Node.js Using Node.js can be very easy to implement an HTTP service, the most simple examples such as the official website example:

Window watchdog (WWDG) is often used to monitor software failures caused by external interference or unforeseen logic conditions that result from an application deviating from a normal running sequence. In short, the difference between the IWDG and

0x00 Preface At the beginning of the article, I 'd like to apologize for the article (about the inheritance of cross-origin character sets) that was recently published with an outrageous conclusion but was deleted in a timely manner. I also hope

ASCIIThe ASCII code is a 7-bit code with the encoding range of 0x00-0x7f. The ASCII character set includes English letters, Arabic numerals, punctuation marks, and other characters. 0x00-0x20 and 0x7f contain 33 control characters.The system that

Missile interception is a classic problem: finding the longest non-ascending subsequence of a sequence, and finding that it can be divided into at least several non-ascending subsequences. The first question is classic dynamic planning. The second

Window watchdog (WWDG) is often used to monitor software failures caused by external interference or unforeseen logic conditions that result from an application deviating from a normal running sequence. In short, the difference between the IWDG and

Requires support for Chinese characters (non-rigid requirements), alphanumeric, decimal, etc., the encrypted string consists of numbers and characters, preferably encrypted and before the length of the encryption such as the "Www.qq.com" string

What is an integer overflow:The problem of the integral type of C language is not unfamiliar to everyone. For an integer overflow, an unsigned integer overflow and a signed integer overflow are classified.for a unsigned integer overflow, the

[Cpp]/* Pay attention to the details. 0x7f in memset differs greatly from 0x7f in constant assignment. The constant value is very small. In memset, values are assigned by byte. Is a large value.This is a variant of the shortest path. It is actually
