Advantages and disadvantages of Nodejs and discussion of applicable scenariosOverview: Nodejs claimed that the goal was "to provide a simple way to build a scalable network program", so what was the problem, what were its pros and cons, and what scenarios it was designed to address?This article explores these issues in terms of personal experience.I. Characterist

Advantages and disadvantages of microservice ArchitectureAbstract: This article is from the official Nginx blog and is the first article in The microservice series. It mainly discusses the shortcomings of traditional monolithic applications and the advantages and challenges of the microservice architecture. As the author said, microservice architecture is more su

classification probability, such as search rankings.The extended softmax of logistic regression can be applied to multi-classification fields, such as handwritten handwriting recognition and so on.Artificial neural network One, the advantage of neural network1, high classification accuracy, learning ability is very strong.2, the noise data robustness and fault tolerance is strong.3, has the associative ability, can approximate any nonlinear relation.

Brother even education in the long ago, answered a question about the back-end language selection, then what are the back-end language, what are the advantages and disadvantages? So brother even share with you a little bit of experience.Language Advantages and disadvantagesC + +C language is very close to the operating system of the language, and the operating sy

DrbdIt is the block-level synchronous replication technology implemented by the kernel module. The synchronization level here can be adjusted. Because drbd uses the network card for block replication. If InfiniBand is used for transmission, high concurrency can be effectively processed. This is a type of replication and storage. It is nothing more like a hot standby machine, rather than a storage ha, it is better to ensure data security. The industria

Three Modes and their advantages and disadvantages of LVS, and three modes of lvs LVS Classification LVS-DR: Direct routing, which is the most common method. All ctor and RealServer are in the same physical network (switch) and have only one Nic. LVS-NAT: address translation, packet back and forth through NAT translation, so Director Server (that is, LVS Serve

What is SSD? A Solid State Disk (Solid State Disk or Solid State Drive), also known as an electronic hard Disk or Solid State electronic Disk, is a hard Disk consisting of a control unit and a Solid State storage unit (DRAM or FLASH chip. The interface specifications, functions, and usage of SSD are the same as those of common hard disks, and the product shape and size are also the same as those of common hard disks. As solid state disks do not have the rotating media of common hard disks, they

, which inevitably leads to potential stability and debugging problems in the initial stage;(2) Linux Bridge relies on a variety of other modules to achieve a variety of functions, and the release time of these modules are often very long, high stability;(3) There is no difference between the core functions, but only in the centralized control and performance optimization of this piece of open vswitch has some new features or optimizations. However, from the test results, there is no significant

Object-oriented and process-oriented programming can only be used in many programming languages, but PHP is different from other programming languages, that is, we can freely choose orIf you are new to PHP, writing code in PHP's process-oriented style may be your only choice. However, if you often go to PHP forums and newsgroups, you should see articles about "objects. You may also see tutorials on How to Write object-oriented PHP code. Or you may have downloaded some ready-made class libraries

inappropriate: A program that is not suitable to do time- efficient (fast algorithm) or very flexible space performance (memory is released immediately), because of intermediate language and compilation process, than c/c++native type of language will be slower , the memory of the active recovery is difficult to release the unnecessary memory immediately, do not use the inline function and destructor (not recommended).Limited support beyond the 2.Windows platform: mono is not mature enough to us

China's vro products have developed very rapidly, so I have studied the advantages and disadvantages of vro products. I would like to share with you here, hoping to help you. Recently, some netizens asked in the Forum: "low-end router products and high-end router products are similar in usage. Why is the price so far different ?" In fact, this question is very good. Many friends who are not familiar with th

In the 2011, one of the focuses of the web industry is the development of HTML5. The author also in a lot of webmaster network to see many of this article, but I found that there seems to be very few directly whether the HTML5 standard Web pages can affect the site's traffic and real and optimize the relationship between the article. The author will be in the end of 2011 published about one year to the author of the understanding of HTML5. First we ne

Recently, a friend asked me how to analyze the advantages and disadvantages of a website, and then extended to how to optimize the site and website promotion work? This problem is in many areas of the proposition, not one or two words one or two articles can be said. This article belongs to the Cubs general idea of a primer on how to analyze the site, how to optimize the site, how to promote the site of a f
