Active "port collision technology"-Good Remote Management

Port knocking ):From the perspective of security management, the more service ports opened, the more insecure the system is. The more secure the system is, the more secure the system security reinforcement service is, it is to first disable useless ports and then implement access control on the ports that provide services. Remote Management and maintenance personnel usually need to open some service ports, such as FTP and SSH. These services use some familiar ports to enable these ports for a lo

Principle of game collision

Game collisions can be roughly divided into these categories1. the collision between the protagonist and the boundary restricts that the protagonist cannot go out of the screen of the mobile phone.2. the collision between the protagonist and the physical layer, as well as the house, tables, chairs, and so on in the map.3. the collision between the main character

Basic Principles of hash table collision attacks

Address: http://blog.jobbole.com/11516/ Source: Zhang Yang Recently, hashtable collision attacks (hashtable collisions as DoS attack) have been mentioned, and many languages have been involved. This article combines the PHP kernel source code to discuss the principles and implementation of such attacks.

Cocos2d-x 3.x physical collision mechanism

Cocos2d-x 3.x physical collision mechanism I recently got another physical engine. Let's write it down. Next we will summarize the knowledge I learned from other blogs and my understanding. The brand new encapsulated physical engine in cocos2d-x 3.X gives developers the greatest convenience, you don't have to bother with the details of various physical engines, the complete encapsulation allows developers to add physical engine mechanisms to their own

Android Research game development Collision detection

 Game collisions can be roughly divided into these categories1. The protagonist and the border collision, limiting the protagonist can not walk out of the phone screen outside.2. Collision with the physical layer, with the map of the House table chair and so on.3. The collision between the protagonist and the game character, here refers to NPC and so on.4. The

Collision detection and response based on 2D polygon (3)

3. Further expansion of Fast Moving ObjectsThe above method will achieve very good results when processing slow moving objects. However, when an object moves very fast, the collision system will lose accuracy, collision, or allow the objects to cross each other. This is not what we expected. Here we still use the separation coordinate axis method, and further expand it, and use this algorithm to detect

Hash collision and Denial of Service Attack

Text/Xuan soul 1. collision between Hash and Hash Hash is a type of output that converts an input of any length into an output of a fixed length. An output of a fixed length can represent the input in "Actual Application Scenario. Hash Functions are usually translated into Hash functions. Hash is usually used to verify information consistency. The implementation of Hash functions is diverse, and the SHA-x Series and MDx series are the most widely used

J2ME 2D Small Game Entry (iv) Join the bullets, realize the collision operation

Computational aircraft games in the bullets are essential, they are numerous and full of the entire screen, these random or have a certain AI small objects, it is not always easy to achieve, sometimes you have to consider a lot of problems related to effectiveness. We defined the Gameobject, to a large extent, to facilitate the reuse of Sprite, because we have a lot of bullets, it is impossible not to add a bullet is a sprite, I need to share the same sprite. We implement it by inheriting Gameob

This article unifies the PHP kernel source code, chats this kind of attack the principle and realizes. The basic principle of hash

My personal thoughts on storing different types of objects for Collision Detection

(Declaration: The following object-oriented ideas are based on C ++ and 2D graphics) In a program with a small amount of code, we may directly encapsulate the collision detection of all required objects in the class, and then Automatic Collision Detection is performed during rendering of actions such as role movement. However, this practice has a drawback, that is, we have known the requirements, If we need
