A probe into the matrix in game development 1. The role of matrices in 3d space(1) box A wants to rotate the 50° around (10,3,4) and twice times in the x direction and 2 units in the direction of (9,-1,8), then after the above transformation, the new box of the coordinates of the various points? The application matrix makes it easy to figure out the answer. (2) Knowing the position of the sub-coordinate system in the parent coordinate system, you can

Probe into the anonymous function of PHP's closure (Closure), Closure When it comes to closures, we have to think of anonymous functions, also called closure functions (closures), which seems to be the main implementation of PHP closures. Declaring an anonymous function is this: $func = function () { };//With a terminator you can see that the anonymous function, because it has no name, needs to be returned to a variable if it is to be used. Anonymo

It's okay to write a small probe to play, because it can only be embedded in the blog and so on, so this is just to get the user information, and I will write a powerful probe later.The Code is as follows:String Agent = request. getHeader ("User-Agent ");StringTokenizer st = new StringTokenizer (Agent ,";");St. nextToken ();// Obtain the user's browser nameString userbrowser = st. nextToken ();// Obtain the

First, let's take a look at our program operating mechanism.Whether it is an object-oriented language or a process-oriented language, the execution of code is ultimately process-oriented. Threads are also the same, where a thread exec

A probe into how the document is storedUncover the mysteries of cold storagePer Brasher The older members of the Internet community are pursuing longer-term solutions. The so-called service period is longer, which may mean MTBF(no fault running time) increased from 3,000,000 to 4,000,000, or 7 years of quality assurance. Regardless of the point of reference, there are some difficult problems involving the document class hard disk. The starting point

is only a necessary condition for determining prime numbers. the integer n that satisfies the condition of the Fermat theorem is not necessarily a prime number. some operators also meet the condition of the ferma theorem ***. these are called Carmichael numbers. The first three Carmichael numbers are 561,1105, 1729.The number of Carmichael is very small. In 1 ~ Of the integers in the range of 100000000, there are only 255 Carmichael numbers. * ** The premise of the Fermat theorem is that a and

In China, the first thing we put smart DNS into the market was even (how can we feel unmodest ). I think the introduction of the VIEW function in BIND9.X is not targeted at China, but this function can solve
