division by 2

Yesterday, I saw a news-Yahoo canceled the QA team, the engineer must be responsible for the code quality, and use continuous integration instead of QA. At the same time, also heard netizens said, "Listen to Microsoft to do Database Operations

Baseband signal is the digital signal 1 or 0 directly using two different voltage to express, and then sent to the line to transmit. The wideband signal is a frequency division multiplexing analog signal which is modulated by the baseband

Abstract: The current CPU multiplication is very fast (about one CPU cycle, or two or three cycles are required, but each cycle can start a new multiplication command ), however, Division as a basic instruction is more than expected. It is a very

[Translation] IP subnet division Original article title: IP subnetting made easy Address: http://articles.techrepublic.com.com/5100-10878_11-6089187.html   IP network engineers need to have a solid understanding of how IP subnet division works.

With the continuous development of IT construction, it O & M has become a necessity for enterprise operation. Although the IT budget of many enterprises has greatly improved compared with last year, it is still very tight in general. Last week, I

TopicThe 2-3-4 tree is a special case of B-trees and is a B-tree with a degree of 2. In the B-tree blog, we implement the B-tree is a template, so to get the 2-3-4 tree, that is, the degree of 2 B-tree is very easy, as long as the declaration can be-

Modulo 2 is a binary algorithm, the core ofCRC calibration technology, so before we analyze the CRC algorithm, we must grasp the rules of modulo 2 operation. In the same way as arithmetic, modulo 2 also includes modulo 2 plus, modulo 2 minus, modulo

IntroductionIn one of my previous articles [ThoughtWorks Code Challenge--fizzbuzzwhizz Game General High Speed (C & C + +)] It was mentioned that the compiler was optimized to handle the division of the divisor as a constant, sorted out today, One
