Linux system has a performance problem, generally we can use top, iostat, free, vmstat and other commands to view the initial positioning problems. Where iostat can provide richer IO performance status data.1. Basic use$iostat -d -k 1 10The

Starting with HTML5, we can start manipulating this history stack.the Window object in the DOM provides a read of the browser history through the Window.history method, allowing you to move forward and backward in the user's access record.

The AVL tree is introduced in the algorithm series (nine) balanced binary lookup tree AVL tree. This article mainly explains the priority queue.Typically, a two-fork heap is used to implement a priority queue. For the time being, this

Rectangle bounding Box algorithm: detects whether 2 rectangles overlap, in such a case to determine whether 2 rectangles collide only need to compare the coordinates of two rectangle vertices. Assuming that rectangle A is used (X1,Y1) for the

PHP kernel exploration: zend_execute specific execution process The function of the interpreter engine to execute the OP is zend_execute, in fact Zend_execute is a function pointer, when the engine is initialized Zend_execute the default

1. Basic ConceptsInternal sorting and external sortingDepending on the sort process, whether the data to be sorted is all in memory, divided into two main categories:Internal sorting: Refers to the sort process that the data to be sorted is stored

Usually a program includes four aspects of algorithms, data structures, program design methods, and language tools and environments. The algorithm is the core, and the algorithm solves the problem of "what to Do" and "How to do". Algorithm is the

"Beauty of Programming", page 183, question 2.14--The maximum value of the sum of the number of words in the subarray. (Array of integers)I began to think that the elements can be arbitrarily drawn from the array into a sub-array, so there is an

Recently, because of the source code in the reading Underscore.js, plus the IFE before the completion of the JavaScript part of the Task2, which a large number of abbreviated sentence wording, especially like?: This trinocular operator is combined

IntroductionThe Iostat is primarily used to monitor the IO load on the system device, iostat the statistics from the start of the system startup when the first run, and then running Iostat displays statistics from the last time the command was run.

　　I said before, the page to export the table as a PDF, through the code I gave intact implementation of its requirements, but not a few days, and said, because my table is a maximum of 26 lines on the page, if the table row more than one, you will

Using Python to achieve dichotomy: my approach to implementation is as follows1, determine whether the value to find is greater than the maximum value, if greater than the direct return false2, determine whether the value to find is less than the

Connection Interface IntroductionThe connection interface is the root interface of the Java collection, there are no implementation classes, only sub-interfaces and various containers that implement subinterfaces. Used primarily to represent a large
