I recently started to learn about. NET and met a good open-source ide sharpdevelop. This development tool is developed using C #. One thing that attracts me is that it adopts plug-in technology similar to eclipse to implement the entire system. This plug-in system is my most interesting place, so I started to study a piece of code. After this article, I will write down my research experiences one after another.

As we all know, C ++ and Java are two mainstream object-oriented languages today. Each person has their own opinions on the advantages and disadvantages of these two languages, the consensus is that C ++ is a compilation-type high-level language while Java is interpreted. Therefore, C ++ is fast and Java is compatible, c ++ is suitable for underlying control while Java is longer than network programming. In any case, it is certain that the two languages will coexist for a long ti
is, the modulus square of the Signal Fourier transformation, the power in the time domain and the power in the frequency domain can be matched by the passal theorem.
Pay attention to the following two points for comparison of power spectrum and amplitude spectrum:
1. the power spectrum is the statistical mean concept of a random process. The power spectrum of a stable random process is a definite function, while the spectrum is the Fourier transformation of samples in a random process. For a ra
Recently, discussions on o/r m suddenly become more intense. I think it is necessary to clarify some concepts here, so that we can only find that the most fundamental understanding has a problem. this article does not guarantee that all opinions are correct, but only my understanding in a specific period of time.

The FileSystem API (file system API) simulates a local file system that a network application can navigate to. You can develop applications to read, write, create, and index files in a sandbox virtual file system.The file system API interacts with other related APIs. It is based on the file write API (the files writer API), and the latter is based on the file API (FileName API). Each API has a different function. These APIs are a huge evolutionary leap forward for web applications, enabling them
