building a security system. 3. Data and Code separation principles 4. The principle of unpredictability Even if code cannot be repaired, it can be considered a successful defense if it can invalidate the method of attack. The implementation of unpredictability often requires the use of encryption algorithm, random number algorithm, hashing algorithm, good use of this principle, in the design of security programs tend to do more with less. The four Principl

On the basis of the purchased control (no source code), want to add some features of Qobject, have to inherit more:Class Myprogress:public cprogress, public qobjectBut always error:Release\moc_my_tool.cpp:80:12:error: ' Qt_metacast ' is not a member of ' cprogress 'Return Cprogress::qt_metacast (_clname);Clear temporary files, recompile a few times, still so, I thought that QT does not support the other class library based on multiple inheritance?Later brainwave, may want to write qobject in the

Satellite communication has played an important role in the global communication field since its emergence in 1960s. With the emergence of the Internet tornado, the satellite Internet technology combined with the Internet has become a new hotspot in the development of satellite communication. Satellite Internet technol

; ~ Meteorological data files on the ground. For ease of communication, the GPS data files in RINEX 2 format are marked with ① no logo; ② ASCII code; ③ each record is 80 characters in length and the block size is 8000; recorded on tape, the first file on the tape is the directory of all files. However, at present, international organizations such as IGS use communication methods (Internet) to quickly extract data from global GPS observation stations for years and store the data in large computer

Remote Sensing Satellite 6 At 10:55 A.M. on July 26, China sent the "China Remote Sensing Satellite 6" to space using the "changzheng 2 C" carrier rocket at the Taiyuan Satellite Launch Center. The launch of "China Remote Sensing Satellite 6" was developed and produced by the Shanghai Institute of aerospace technology,

Recently, because of the relationship between Sino-2 and Beidou, many netizens posted the Tle data indicating the orbit of the satellite. Here is a brief introduction to the satellite orbital parameters and the format of the tle. Although no one actually reads the TLE data directly, it is the use of software to obtain satellite orbit and location information, but

first, Kepler's LawThe three Laws of planetary motion proposed by German astronomer J. Kepler. The first and second laws, published in 1609, were summed up in Kepler's data from the observation of the Martian position in the valley of astronomers; the third law was published in 1619. These three laws are called the Ellipse law, the area law and the harmonic law respectively.The contents of the Three laws:Kepler's First law (orbital law) all planets orbiting the Sun are elliptical, and the sun is

SKYBLASTERTM Interactive Satellite communication system is one of the most technologically advanced VSAT systems in the world, and it has the ability to provide broadband video and data information directly to LAN or desktop office systems. Its biggest feature is that the remote station is a microcomputer as a function of receiving and launching is installed on the computer motherboard on the receiving card and the launch card completed. Combining dig

1 OverviewA TCP/IP network system for measurement and control, transmitting multimedia information including video, voice, and real-time data. Because the system runs in an inaccessible environment, the evaluation of its service carrying capacity and transmission quality needs to be carried out on the simulation system, including the construction of a network experimental platform, the design of reasonable measurement methods, and the development of Performance Testing integrated software.
