The first 2 methods are mainly used in list parsing, performance is slightly poor, and the last use of the generator expression, compared to list parsing, more memory-saving List resolution and builder expressions are similar: List resolution

Kmeans is a classical algorithm in clustering, and the process is as follows:Select K points as the initial centroidRepeatAssigns each point to the nearest centroid, forming a K-clusterRecalculate the center of mass of each clusterUntil clusters do

Problem Description: The main land of Japan called Honshu is a island surrounded by the sea. In such-an, it's natural to ask a question: "Where's the most distant point from the sea?" The answer to this question for Honshu is found in 1996. The

application processing load or network traffic load. This scenario is ideal for nodes that run the same set of applications. Each node can handle a portion of the load, and the load can be dynamically allocated between nodes to achieve balance. This is true for network traffic as well. Typically, a single node cannot be processed quickly for too large network traffic, which requires sending traffic to other nodes. It can also be optimized based on the different available resources on each node

means that each shader unit inside the GPU has become larger. During this DirectX 11 upgrade, the following features are worth noting: ● The version of The Shader Model is upgraded to Shader Model 5.0. It adopts the object-oriented concept and supports double precision data.● Tessellation surface subdivision technology was officially supported by Microsoft and gradually matured;● Multithreading multi-threaded processing, making graphic processing no longer embarrassing to the multi-threa

insecure browser-thin client brings two challenges: reducing application security and increasing security costs. Many web Front-end applications are not even considered to be attacked during development .. In this context, a new technology, Web application firewall. It can effectively reduce the implementation cost of website security. Barracuda application firewall is the leading product of this emerging product. The old method does not work. In the

Now, the market exists a large number of true and false Web application firewall products, the user's understanding of it is not clear enough, coupled with the industry's lack of Web application firewall measurement standards, Web application Firewall evaluation of the good or bad becomes very difficult. In fact, to choose a good Web application firewall is not difficult, the following aspects can be examined: 1. Attack interception capability The primary function of WAF is to protect against
