The C method is thinkphp used to set up, get, and save configuration parameters with a high frequency. Understanding the C method requires first understanding of the next thinkphp configuration, since all operations of the C method are related to configuration. The thinkphp configuration file is defined using the PHP array format. Because of the use of function overload design, so the use of more, we come to one by one notes. Set parameter C (' db_name ', ' thinkphp '); Indicates that the value of setting the Db_name configuration parameter is thinkphp, due to configuration ...
Content Summary: The data disaster tolerance problem is the government, the enterprise and so on in the informationization construction process to be confronted with the important theory and the practical significance research topic. In order to realize the disaster tolerance, it is necessary to design and research the disaster-tolerant related technology, the requirement analysis of business system, the overall scheme design and system realization of disaster tolerance. Based on the current situation of Xinjiang National Tax Service and the target of future disaster tolerance construction, this paper expounds the concept and technical essentials of disaster tolerance, focuses on the analysis of the business data processing of Xinjiang national tax, puts forward the concrete disaster-tolerant solution, and gives the test example. Key words: ...
FFTW is the Faster Fourier Transform in the "West" abbreviation, is a fast C FFT library. It includes complex, real, symmetric, multidimensional, and parallel transformations to efficiently handle the size of any array. Speed is faster than other free FFT installations, even better than vendor-tuned libraries. To achieve this performance, it employs new code generation and Run-time optimization techniques as well as many other techniques. FFTW for any size pattern generation ...

There is a concept of an abstract file system in Hadoop that has several different subclass implementations, one of which is the HDFS represented by the Distributedfilesystem class. In the 1.x version of Hadoop, HDFS has a namenode single point of failure, and it is designed for streaming data access to large files and is not suitable for random reads and writes to a large number of small files. This article explores the use of other storage systems, such as OpenStack Swift object storage, as ...
It would be faster to enclose the string in single quotes instead of double quotes. Because PHP searches for variables in double-quoted strings, single quotes do not. Note that only echo can do this: it's a "function" that takes multiple strings as arguments, Echo is a language structure, not a real function, so the function with double quotes). 1, if you can define the class method as static, as far as the definition of static, it will speed up nearly 4 times. 2, $ row ['id'] speed ...
