1 PrefaceAfter 3 days of tossing, studied the Linux installed several methods of QQ, summarize, Linux installed QQ method mainly has the following several: Install WINEQQ International Edition VirtualBox install Windows, install QQ, and then turn on seamless mode Genymotion Simulator install Android QQ Crossover installing TMQQ2013 or DEEPINQQ First of all, Linux does not have a way to achieve the kind of Window

for both ends of parallel lines. In general, the industry uses the T568B standard! Remember!!! One end of the intersection uses the t568a line sequence, and the other end uses the T568B line sequence. 2 When to use parallel lines, when to use the intersection line? Parallel lines are used to connect different devices together: Computers to switch crossover lines are used to connect the same devices together: computers to computers, switches to swi

deepin-qq and so on. Even the crossover Volume license was purchased to CodeWeavers, allowing each user using Deepin to use crossover free of charge, and developed many crossover-based wine software.In fact, in the case of wine-qq8.9.1, the Deepin team maintained a total of two versions, one deepin.com.qq.im (based on Deepin-wine) and the other app.com.qq.im (ba

There are two functions in a tourselect.c file:Selection (population *old_pop, population *new_pop)Individual* Tournament (individual *ind1, individual *ind2)First, the code of the first function is as follows:1 /*Routine for tournament selection, it creates a new_pop from Old_pop by performing tournament selection and the Crosso Ver*/2 voidSelection (population *old_pop, population *New_pop)3 {4 int*A1, *A2;5 inttemp;6 inti;7 intRand;8Individual *parent1, *Parent2;9A1 = (int*)ma

Next, we will introduce the specific concepts and some applications of the HART communication protocol. Then we will analyze the products related to the RS232 converter. Help you understand the concept of the HART communication protocol. First, let's take a look at the specific content of HART. HART (Highway Addressable Remote Transducer), an open communication protocol that can address Remote sensor express connect, it is a communication protocol bet

How to install PL/SQL developer on Linux工欲善其事 its prerequisite, PL/SQL and Toad are important tools for Oracle practitioners, but none of these tools have a Linux distribution, and if you want to use these tools on Linux, you needWine or crossover This Windows application Simulator, crossover is wine's enhanced version, nonsense said, the following starts to demonstrate the installation steps:1: Environment

Google Chrome is a Web browser launched by Google. It is simple, secure, stable, and fast! Although Google promises to launch the Linux version, there is no clear timetable. However, we know that GoogleChrome is built on the open-source GoogleChromium browser project. Since Chromium is open-source, we can compile a GoogleChrome program based on Chromium and run it in Linux. Google Chrome is a Web browser launched by Google. It is simple, secure, stable, and fast! Although Google promises to laun

shape such as m or three-headed top, the stock price may change from strong to weak, and the stock price is about to drop sharply, stocks should be sold in a timely manner. If the stock price curve also appears in the same form, it can be confirmed that the decline can be determined using M-headed or triplicate theory. 2. When the kdj curve is low below 50, if the trend of the kdj curve changes from weak to strong, the stock price is about to rebound upwards, and a small amount of shares can be

general, during the overall increase and fall of a stock, the DMA line and the AMA line in the DMA indicator may have two or more "golden crossover" and "Death crossover.1. When the stock price goes down for a long period of time and the DMA line begins to go up and beyond the AMA line, it indicates that the stock market is about to grow stronger, and the stock price decline has ended and will stop falling

likely to participate in reproduction, and fewer offspring.heredity and mutation : The new individual inherits the genes from each part of the parent, and at the same time has a certain probability of genetic variation.Simply put: the reproductive process, the genetic crossover (Crossover), Gene mutation (Mutation), Fitness (Fitness) low-level individuals will be phased out, and more adaptable individuals

These three signal lines can be replaced by twisted pair wires in integrated cabling. To avoid electromagnetic interference in space, the signal line of the card reader should be shielded. The other two signal lines can be shielded or non-shielded. Remote signal line There is a signal li

one of the three signals is down, the physical state of the router serial port is in the state of Down). In addition, if the No DETECT DSR-DTR command is configured on the serial port of the router, the DTE side (router) does not detect whether the headend is sent over the DSR and CTS signals, and the physical layer is reported up as soon as the DCD signal is detected. 2, if the router's serial port configuration of the Flow control command (the specific command is FlowControl Auto), RTS and CT

interrupt, you can compile a program with a more complex structure. Such a program can do one thing and monitor one thing. Once something is monitored, interrupt what is being done, process monitoring, of course, you can also monitor multiple things, the image analogy, the interruption function enables the single-chip microcomputer to have a bowl, look at the pot function. The above three steps are equivalent to killing the dragon and giving up the eight-handed martial arts. You can barely prot
