Node. js exports, module. exports, and ES6 export, export default in-depth explanation, node. jses6 Preface Recently, it is rare to have time. I decided to learn node programming again in a standardized manner. However, the introduction module I see uses the require method, and I think of our ES6 various export and export default.

The main purpose of this paper is to use a linear transformation matrix to solve the parametric eigenvector in the maximum likelihood (ML) criterion. Under the ML criterion, the criterion for evaluating a model ' good or bad ' is the likelihood of the training data matching the model, and if the likelihood is higher, we say the model is better. Mllt's authors give the disadvantage of using diagonal covariance matrices under the maximum likelihood criterion (ML) and the loss of the likelihood of

Hough Transform Hough Hough transform (Hough) is a very important method to detect the boundary shape of discontinuous points. It realizes the fitting of line and curve by transforming image coordinate space into parameter space. 1. Line Detection 1.1 Linear coordinate parameter space In the image x−y X-y coordinate space, the line through the point (Xi,yi) (x_i,y_i) is represented as:Yi=axi+b (1) \begin{equation} y_i=ax_i+b (1) \end{equation} Th

Recently, I used an online music listening software, which has many good stories for children. However, online music often experiences intermittent disconnection, and the software requires more than 1500 credits to download the entire page. To meet the credit conditions, you need to manually install dozens of recommended applications. Therefore, the attack is decided.

　　Problem description 　　Xiao Ming's company every month to pay Xiao Ming, and Xiao Ming received wages for the payment of personal income tax after the wages. Assuming that his one-month pre-tax salary (after deducting five of the risk of a gold, not withholding tax before the wages) is S-yuan, then he should pay the personal income tax according to the following formula calculation:1) Personal income tax threshold of 3500 yuan, if S not more than 3500, then do not pay taxes, more than 3500 yuan

Computer network summary 1. p110 indicates the MAC frame format in V2 format. The data field (that is, IP packet) length ranges from 46 bytes to 1500 bytes, which is defined for Ethernet, "1500 bytes" is also called the Ethernet MTU (maximum transmission unit, that is, Ethernet limits the maximum length of IP datagram to 1500 bytes ). P185 indicates the IP datag

This indicates that the maximum transmission unit MTU from the client machine to 10.1.70.1 is 1472 + 28 (the length of the packet header encapsulated in the Ethernet) = 1500, and all packets larger than 1500 need to be cut. The default MTU in Ethernet is

For details, see Http://www.delphibbs.com/delphibbs/dispq.asp? Lid = 726166 Wheel learning Note 1: UDP programming in Ethernet 1. During UDP programming, the most common question is how many bytes are sent at a time?Of course, there is no unique answer. The answer to this question varies with the requirements of different syste

Recently in because of learning remoting, purely just to understand, found that remoting is really good things. We usually have three ways to use remoting, one is First type: Publishing a public objectExposed objects are created on-premisesSecond type: Remote creation of a public object (SAO)Object creation in the client requestThird type: Remote creation of a private object (CAO)object is created on the host, the client references the object on the server I do not have a good understanding of

The maximum size of a UDP package can be larger. 1. When programming with UDP, we are most likely to think of the problem of how many bytes are sent at a time? Of course, there is no unique answer. The answer is different from the requirements of different systems. Here I only analyze the situation of sending chat messages like ICQ, in other cases, you may also get some help: First, we know that TCP/IP is generally considered a layer-4 protocol system, including the link layer, network layer, tr

~ 1500 bytes. · FCS-this field contains a 32-bit Cyclic Redundancy Check (Cyclic Redundancy Check, CRC) value to verify damaged frames. The initial Ethernet II frame format has some drawbacks. To allow conflict detection, 10 Mbits/s Ethernet requires the minimum group size to 64 bytes. This means that if the frame length does not reach the standard, 0 must be used to fill the short frame. Therefore, the upper-layer protocol must contain a "length" f
