linux control fan speed

How to Implement Version Control for shared libraries in Linux Linux systems also face the same issues as windows, and how to control multiple versions of dynamic libraries. Windows was not well handled before. Therefore, we have a special term to describe this problem "DLL hell", which seriously affects software upgr

Article Title: linux touchpad control. Linux is a technology channel of the IT lab in China. Some basic categories, such as desktop applications, Linux system management, kernel research, embedded systems, and open-source systems, have encountered a problem today, saying that the touchpad can be opened by executing the

1. Trickle Introduction Trickle is a lightweight user space bandwidth control tool used to limit network bandwidth such as browser Firefox, FTP, SSH,CURL,WGET,SCP, and so on.Trickle controls and restricts the upload and download speed of applications by controlling the read and write of socket data. Note that Trickle uses dynamic linking and loading, so it is useful only for programs that use the Libc.s

Thread synchronizationIn real life, some things must be carried out in order, only after I finished, you can in my work on the fruits of the work; This is the most straightforward explanation for thread synchronization.This is also the case in the design of the program. What is the synchronization of thread synchronization? It synchronizes access to shared resources (memory areas, public variables, etc.) or critical areas. Sometimes, these shared resources and critical areas, can only tolerate a

for later access useRegardless of which thread calls Pthread_key_create (), the key created is accessible to all threads, but each thread can fill a key with different values according to its own needs, which is equivalent to providing a global variable with the same name and different valuesThis function is often used in conjunction with the function pthread_once so that the key is created only once函数原型intconstvoidvoid * pthread_getspecific(pthread_key_t key) 说明pthread_setspecific()将pointer的值（

necessarily the whole list, under WINDOWS, the best way is to allocate memory with VirtualAlloc . He is not in the heap, nor in the stack , but directly in the process of the address space to retain a piece of memory, although the most inconvenient to use. But the speed is fast, also the most flexible. So how do I delete the deletion? How do you know how much to delete? This size is recorded by the system. No problem, just the free (), delete ().If

written in memory buffer, and so on to meet certain conditions (such as a certain number or encountered a certain character), The contents of the buffer are then written to the file once. This technique greatly increases the speed of file read and write, but it also brings trouble to programming. For example, there are some data that have been written to the file, in fact, because they do not meet the specific conditions, they are only in the buffer,

The thread is the smallest unit that runs independently in the computer, the running resource is very small, the macroscopic on-line process executes simultaneously. Micro-CPU control by allocating time slices through the system alternately executes the code in the thread. Of course, multi-core situations can be parallel. directory thread benefits thread-private data-thread synchronization method Advantages of threads 1. Save resources and save time.

definition of the processA process is a run-time activity of a program with a certain independent function.characteristics of the processDynamic: The essence of a process is the process of execution of a program. The process is dynamically generated and dies dynamically.Concurrency: Any process can execute concurrently with other processesIndependence: A process is a basic unit that can run independently, and also an independent unit for allocating resources and scheduling.Asynchrony: Because of
