Sometimes when we execute a command, we prompt:[Root @ localhost ~] # Iptraf-Bash: iptraf: command not found I believe many of my friends will often encounter this problem.To solve this problem, you need to install the corresponding software package. In many cases, the command name is not necessarily the software package name,The iptraf command here happens to be the name of the software package, which is a better solution. It is OK to directly install the software package. As follows:Yum instal

ratio float sizePercent; // x position int xLocation; // y position int yLocation; // transparency float alpha; // float direction int direction; // floating speed int speed ;} To get some of the above data, we first write some data or methods: 1. In order to initialize the location of the planet, we use arrays to first define the location of a group of planets (based on the ratio of the view width to the height). Of course, you can also be random, but a random heap may occur: private static

Multiplier Starting from 80486, the CPU has developed rapidly and the frequency has risen sharply. The memory has become unable to keep up with the CPU development pace! Intel decided to introduce the concept of frequency doubling (clock Doubler) in 80486! The memory still works on the system bus and maintains the same operating frequency as the system bus, while the actual internal operating frequency of the CPU (that is, the CPU clock speed we often say) is: CPU clock speed = External freq

kb/s, in terms of data, edge is three times that of GPRS. In addition, people who often use the GPRS Service experience it. When the GPRS throughput data volume is large, it is easy to cut off or even cut off, while edge stability is much more stable than GPRS. It is worth mentioning that the uplink and downlink speeds of GPRS are the same, both of which are 20 kb/s, while the uplink and downlink speeds o

, processing, result return, dynamic web page generation, database access, and application execution, are all done by the Web server. As windows embeds browser technology into the operating system, this structure has become the preferred architecture for today's application software. Obviously, B/S structure applications are greatly improved compared with traditional C/S structure applications. The main characteristics of the B/S structure are strong distribution, convenient maintenance, simple

Index Full table Scan: The worst efficiency of data retrieval (select) is full table scan, which is to find data in one row. If there is no directory, You need to flip the Chinese Dictionary page by page. If you have a directory, you only need to query the directory. To improve the search speed, you can add columns that are frequently searched.Index, equivalent to creating a directory. To create an index, right-click the Table Designer and choose "index/Key"> "ad

Slow webpage access how to find out why the Internet access speed is slow Source: China IT lab Author: Qs Comment font size: Large | Medium | Small In network management, network administrators often encounter slow access speeds between hosts in the LAN and web pages through Browsers (usually Internet access. 1. webpage access In network management, network administrators often encounter slow access

search engine is "Comprehensive" and "accurate", the user will be satisfied. If you optimize the results to make them more effective for the user, the user will be highly loyal to the search engine. For users, the technology doesn't matter. To achieve the goal, the technology will continue to improve from low to high, and the customer will be satisfied if the demand is continuously met. User happiness is the second level. The technology comes from the needs and meets the needs of users. If th

Nor and NAND Nor and NAND are both Flash technologies. Nor is developed by Intel. It is somewhat similar to memory and allows direct access to any memory unit through an address. The disadvantage is: low Density (Small capacity), low write and erase speeds. Nand is developed by Toshiba. It features high density (Large capacity) and fast write and erase speeds. However, it can only be accessed after address

method of the Set object. You can only use the iterator to operate elements. Slow list: the bottom layer uses the Linked List data structure, which provides fast addition and deletion speeds and slow query speeds. The difference between add get and remove is added. When you obtain an object, you do not need to delete it.The empty list of PEEK poll is provided after 1.6. If no exception is thrown, null is r

protocols such as imodem, jmodem, bimodem, Kermit, and lynx. Since most vendors do not support these protocols, I will skip them here. Securecrt can use the zmodem protocol in Linux to quickly transfer files. Set the upload and download Directories Before transmission: Options-> session options-> terminal-> under XMODEM/zmodem Then you can use x/y/zmodem to transmit data. Zmodem uses two commands to transmit data: SZ: Send the selected file to the Local Machine RZ: running this command will

Problem DescriptionWhen you use a vro to access the Internet, the network speed is slow or unstable, and packet loss occurs on the ping Internet, as shown in the figure below:Ping packet loss is generally caused by physical connection quality or line congestion. We will analyze and troubleshoot the factors that are most likely to cause such problems. Please follow these steps to check:Troubleshooting1Reduce wireless signal interferenceIf the wireless signal is strongly disturbed, packet loss is
