Under Gnu/linux, when you need to open other format files, we usually go into the directory where the file is located, double-click Open, very effective. In fact, you can open these format files, even Web pages, by command Xdg-open, as simple as opening a file. Under Gnu/linux, text files are usually opened using the command line, such as commands Gedit, more, cat, vim, less. But when you need to open othe

Using GSL (GNU scientific Library) in the Visual Stdio environmentThe GNU Scientific Library (GSL) is a library of open-source scientific computing functions that are very powerful. There are a lot of articles on the Internet, and GSL's documentation is very good, which is a very easy-to-get-started function library. There's not much to GSL about.Today's talk about how to use this library in a Visual stdio

Introduction In this article, we will learn about the GNU/Linux pipeline. Although the pipeline model is very old, it is still a very useful inter-process communication mechanism. We will learn what a semi-bidirectional pipeline is and what a famous pipeline is. They all provide a FIFO (first-in-first-out) queuing model to allow inter-process communication. MPs Queue Model A Visualized pipeline is described as a unidirectional connector between two en
