The whole framework of 1.c# 's handling events is actually an application of the Observer pattern .Viewer mode: the teacher monitors The students ' exams, and if the students cheat , the teacher immediately hits2.

One of the great advantages of webapp is that it can have an animated effect comparable to native when the view is switched on, but most of the time it's just an idea, but the real situation is not the reason for this problem: ① phone CPU sucks! ② Phone card bad! Even if the quad-core rendering is also very problematic ③ high-end mobile browser will have Bug④ low-end mobile phone support is not good (domestic shanzhai machine laugh without words) beca

• Heat Exchange devices and Natural Cooling: Cooling outdoor temperatures can regulate the temperature of data centers at specific times of the year or in certain areas. The heat exchanger can act as part of the air conditioning system and allow free cooling. Heat Exchange Equipment sucks in the cold air, cleans up any external impurities, and then uses the cold air to reduce the temperature of the data center. Nat

what technology you delve into in the future, there will always be men of God in the field, who can surpass 10 of the value of 1 people, have a very complete and esoteric understanding of the technology, and have a very elegant solution to difficult questions. These people determine the future of technology, such as the current large commercial software on the market, many of them are the structure of a few people to complete, follow-up by many engineers to maintain, update.Do you want to be th

A few months later, when the IPhone was on sale, the research group and the manufacturers had a meeting. I asked them what they thought of the IPhone, the chief engineer said, "The phone's microphone sucks."This is not wildest words is a truth, it conveys such a mess

time, I used MATLAB to do a non-lens imaging software, the teacher said it is too ugly, and can not run alone (must be run under the MATALB program), to change other ways. OK, you say change, then I will change, and then began to look at C + +, to the library borrowed a lot of books, every day constantly reading, feel that period of time is quite sufficient, usually on class, idle code code, listen to a few ditty. The days are so past, the software is in the shape of the day, in fact, there is

When the parameter r is taken as the whole positive real number, the solution of the equation can have and cover the entire plane only once.Similarly, the hyperbolic can also take the same approach to the introduction of parameter R, of course, can also do the appropriate treatment so that the centrifugal rate changes with the R, but it is important to note that the hyperbolic
