you need (the requested resources), then when you know the store address (URL), you will go past the store (initiate the request), tell the store what you want, then the store to find the goods (processing requests), Then sell it to you (in response to the request). However, the store feels that the goods sold are too simple, in addition to the original daily necessities (get), but now also added jewelry (post), electronic devices (put) and other pro

The benefit is that the zero page is highly efficient, and it does not need to be allocated or recycled from the memory manager. Remove the reputation of the zero page, so it can return to the kernel mainline. As for another side effect of the zero page, it will lead to additional page defects, after all,

browser is different), this time using the Keep-alive feature , to establish an HTTP connection, you can request multiple resources, the order of downloading resources is in the order of the code, but because each resource size is different, and the browser and multi-threaded request resources, so from the point of view, the order shown here is not necessarily the order in the code.When a browser requests a
(); Vector3 lastCarDir = trackPoints[i] - trackPoints[i - 1]; lastCarDir.Normalize(); Vector3 perpDir = Vector3.Cross(carDir, lastCarDir); Vector3 centriDir = Vector3.Cross(carDir, perpDir);
Because centriDir points to the inside of the curve, the track barrier must be perpendicular to this vector.
For the above reason, you need to add this vector to the normal vector of each vertex of the track. This will make the side vector slowly perpendicular to
Most PHP programmers now use a process-oriented approach, because parsing a Web page itself is very "procedural" (from one label to another). Embedding process code in HTML is straightforward and natural, so PHP programmers often use this approach.
If you're just in touch with PHP, writing code in

We all know that the HTTP protocol itself is stateless, and the client simply sends a request to the server to download some files, and each request that the client sends to the server is independent. For the current Web application, http "stateless", causing many applications to spend
