subtract 1

A long time ago, I saw the algorithms for special effects on water waves and recently the algorithms for special effects on flame. There are many similarities between the two, I have translated an article on flame effects. For more information, see.

Tetris is a memory of childhood. From the black and white game machines on the palm of the hand to TV game machines to computers, there is no trace of it, today, let's review one of its implementation methods. It's just a matter of sorting out my

Join the predicer A [M, N] estimator uses the first M branch behavior to select from 2 ^ m branch prediction. Each prediction corresponds to the n-bit prediction of a single branch. The attraction of this branch estimator is that it achieves a

The threading module provides a high-level thread interface, based on the low-level _thread module implementation.Basic methods of modulesThe methods that are fixed by the module are as follows:Threading.active_count ()Returns the number of thread

The role of Semaphore:In Java, the use of the Synchronized keyword and the lock lock enable concurrent access control of the resource, allowing only threads to access the resource in the critical section at the same time (except for read locks), the

1. The first and most important article is to introduce it: hide . (static function, static variable all available)When multiple files are compiled at the same time, all global variables and functions that do not have a static prefix have global

Originally from: http://book.51cto.com/art/201211/367161.htmUsing new to create a dynamic array (1)If a program requires only one value, a simple variable may be declared because it is easier to manage a small data object than to use new and

Title DescriptionFlappy Bird is a rage casual mobile phone game. Players need to constantly control the frequency of clicking on the phone screen to adjust the bird's flight altitude, so that the bird smoothly through the screen to the right of the

Stack (stack) represents a special linear table that can only be inserted and deleted at a fixed end (usually the end).Stack: 1) Let the top reference point to the newly added element, and the next reference of the new element points to the original

The concept of concurrency control----concurrency refers to the parallel execution of multiple execution units, while concurrent execution units share resources (hardware resources andAccess to global variables, static variables, and so

Encounter problemsRoost in the development process encountered a problem, there was a service is mass mail, because one send dozens of hundreds, so the use of multi-threaded to operate.In unit testing, I tuned this method to test the mail sent, the

1, what is a heapA heap is a complete binary tree with the following properties:The value of each node is greater than or equal to the value of its left and right child nodes, referred to as the large top heap (example 9-2, shown in the left

The previous article discussed the mutex, condition variables, read and write locks and spin locks for thread synchronization, this article will first discuss the use of barriers and semaphores, and give the corresponding code and considerations,

1.NOT The bitwise operator is not represented by ~. The essence of the not operator is to negate the number and then subtract 1. The bitwise operator NOT is a three-step process. A. Converting an operator to a 32-digit number B.

This section is mainly about the implementation of read-write locks.As mentioned in the previous section, Readwritelock appears to have two locks: readlock/writelock. If it's really two locks, how do they affect each other?In fact, the realization

Topic:Given a string source and a destination string target, a substring containing all the target string letters is found in the string source. PrecautionsIf there is no such substring in source, returns "", if there are multiple such substrings,

Preface?? In order to handle synchronization between threads, the JDK provides several useful concurrency tool classes in addition to the lock mechanism: Countdownlatch, Cyclicbarrier, Semphore, Exchanger, Phaser;?? Countdownlatch, Cyclicbarrier,
