: multithreading is a means and tool for asynchronous implementation. We usually equate multithreading with Asynchronization, which is a misunderstanding. In actual implementation, there are many implementation methods for Asynchronization. We can use processes for Asynchronization or thread, or some hardware features. For example, when implementing asynchronous Io, there are two solutions: 1) You can initialize a sub-thread and perform I/O in the sub-thread, so that the main thread can run smoo

drawing a trigonometric image, We can also easily verify $$\cos x = \sin (x+\frac{π}{2}) $$ and $$\sin (π-x) = \sin x$$ And then we can start proving that (This certificate was taken from the American Journal of Mathematics, 109th February 2002 pp. 196-200 author department Josef Hofbauer) Because $\sin (2x) = 2 \sin x \cos x$ So $\sin x= 2 \sin (\frac{x}{

a session header process may have a control terminal. A process group may have a process group first process. The process ID of the process group's first process is equal to the process group ID. Here is possible, under certain circumstances is not. The process that interacts with the terminal is the foreground process, or the background process. Sighup will be sent to the appropriate process in the following 3 scenarios:1. When the terminal is closed, the signal is sent to the session first pr

Linux as a PPP Access Server (2) -- Linux Enterprise Application-Linux server application information. The following is a detailed description. When you think that all necessary functions are added or made into modules as needed, you can try to run the following command: # Make dev; make clean; make zlmage; If the system finally prompts that the new kernel exists in/usr/src/linux/arch/i386/boot, the kernel is compiled successfully.

Given that tomorrow is 30, it may not be time to open the computer, so take advantage of the night (and now the next day) to write down the second chapter of Linux is what the experience. Anyone who has ever used Linux knows that it is an operating system and has a tendency to replace Windows incrementally. So what exactly is Linux? This has to mention a person-torvalds (take off socks), the core of Linux is the prototype he put forward in 1991. The s

This operation is completed through the cancel request. The request has its own transaction, but involves the canceled transaction (Chapter 1 ).
