Sometimes, read and write files do not want to use the system cache (page cache), when the direct file read and write comes in handy, using the method:(1) When opening the file, add the O_direct parameter:You need to define _GNU_SOURCE, otherwise you cannot find the O_direct macro definitionSample fragment:#define _gnu_source int FD = Open ("test.out"0644);View Code(2) The transfer data size and buffer address of the read-write operation need to be a

[Basic idea]Key: Find the right insertion position in the sequence that is already sorted in frontSteps:1. Starting with the first element, the element can be considered ordered.2. Take the next element and compare it in a sequential sequence of elements from a backward-forward scan.3. If the element (sorted) is greater than the new element, move the element to the next position.4. Repeat step 3 until you find that the sorted element is less than or equal to the position of the new element.5. In

Direct Assignment: is actually the object's reference (alias). shallow copy (copy): copies the parent object and does not copy the inner sub-object of the object. deep Copy (deepcopy): The Deepcopy method of the Copy module, which completely copies the parent object and its child objects. Example of a shallow copy of a dictionary={1: [1,2,3]}>>> b = a.copy()>>> a, b({1: [1, 2, 3]}, {1: [1, 2, 3]})>>> a[1].append(4)>>> a, b({1: [1, 2, 3, 4

agile, the use feels more comfortable, reduces the operation the repetitive ponder, the pause point is more promising. In fact, a comfortable navigation, in addition to the induction clear, easy to operate, at first glance it is also very important to see the impression ~ It is a good habit to put all the details in front of others in one breath. Some navigation although powerful, but the content of a large, functional a high-level, look at the annoying. This time, you need Solution Selectio

To start the Metro application directly on the Windows 8 desktop, if you want to start the Metro application directly on the traditional desktop without having to go to the Metro interface, you just need to create a shortcut to get it done. The Metro interface is actually a shell of the explorer, which simply means that the Metro menu is a feature added to the Explorer.exe process. Direct launch of Metro application on Windows 8 desktop: Right-click

Inserts the sort directly, and its insertion position is determined by comparing the size of the record to be inserted with each record in the ordered area from right to left. This example uses the direct insertion method to sort the numbers from small to large.#include Direct Insert Sort

Python Direct mouse Keyboard controlBefore because of the reason for the final period has been a long time without blogging, Bo today found a fun module Pyautogui, with it can use Python script directly control keyboard and mouse, feel can solve a lot of boring mechanical movement. Here's a record of learning.Installation$ sudo pip install pyautoguiThere may be more dependent packages installed, just wait patientlyBasic use=# 屏幕尺寸=# 返回当前鼠标位置，注意坐标系统中左上

above two modes of interaction are more commonly used, and a recent project has encountered a special application requirement. You need to check the pages of Unity Web Player into the Flex application framework and complete the flex interaction directly with unity Web player.To complete this requirement, the following questions need to be addressed:1, how to check the HTML page into the Flex container;2, how to achieve the flex and Unity Web Player direct
