Link analysis algorithm: Salsa algorithmThe original intention of the salsa algorithm is to combine the main features of the PageRank and hits algorithms, which can take advantage of the characteristics of the hits algorithm and the query, and also
Link analysis algorithm: Hilltop algorithmThe hilltop algorithm was studied by Krishna Baharat in the year 2000, and was patented in 2001, but many people thought that the hilltop algorithm was researched by Google. Just Krishna Baharat later joined

Design mode (18) Policy mode strategy (object behavior type)1. Overview
In software development also often encounter similar situation, to achieve a certain function has a number of algorithms or strategies, we can choose different
the 10 major programming maxims that every programmer should know
Programming Maxim 1: Smoke (There is no smoke without fire)
Programming Maxim 2: Prevention, treatment supplement (an ounce of prevention is worth a pound of cure:)
Mass data processing is based on the storage, processing, and operation of large amounts of information.The so-called Mass, is a large amount of data, may be terabytes or even PB level, resulting in the inability to load memory at once or can not be
Design mode (19) Template method mode (class behavior type)1. Overview
In object-oriented development, we typically encounter a problem where we know the key steps required by an algorithm and determine the order in which these steps are
Write a program to check whether a given number was an ugly number '.Ugly numbers is positive numbers whose prime factors only include 2, 3, 5. For example, 6, 8 was ugly while the is not ugly since it includes another prime factor 7.NoticeNote that
