liminal thinking

There was a lot of reading on the Internet application architecture talk, but later in practice it was found that the efficiency of using WCF service layer technology to achieve website access was problematic. My intention is to solve the business logic in the WCF middle tier for each platform invocation, but still bring a lot of trouble, not the best practical solution. WCF is prominent in enterprise-level development of SOA. However, we should use WEBAPI technology to realize multi-platf

Save Num and Count, and then implement the comparator interface.You can sort by rules.The code may not be very streamlined, and if there is a better way, you can thread the description.The code is as follows:Package Sds;import java.util.*;p ublic class Main {public static void main (string[] args) {//Accept in

Solution One: The time complexity is O (n*n), all groups of violence.Solution Two: Time complexity of O (2*n).Idea: Array preprocessing, constructing two auxiliary arrays--left interval array, right interval arrays. The maximum value of [0, I] is stored in the left interval array as l[i]. The maximum value of (I, N] is recorded as r[I], and the array is finally traversed.Solution Three: Time complexity O (N).Idea: Find the largest number in the array max, minus the difference between the smaller

accelerated by the use of generics.Because the runtime eliminates generic object instance type information such as defects are often tseung sick, Java and JVM Development also try to solve this problem, such as Java by adding the Type deduction auxiliary information when generating bytecode, so that the reflection interface can obtain some of the generic information. By improving the implementation of generics in the JVM, it supports basic value type generics and direct access to generic inform

"JSP technology is much later than PHP, ASP technology, and JSP technology is now being used to develop very large web sites, but not because the JSP technology itself is very good, but because it is generated on top of Java." This era of ASP, PHP, JSP and other dynamic Web technology, there is a common point is that you visit the URL address, the

RAC employing more and more, essays and blogs are more and more, the threshold of learning has been greatly reduced. And I think beginners do not have to start with all the operations and concepts are understood, you can start from the simple use o

First of all, in fact, the idea of drag-and-drop effect is very simple. There are three main steps: 1.onmousedown, start the drag-and-drop event, recording the original coordinate parameters of the dragged element. 2.onmousemove, real-time record the distance of th
