The pipeline is the earliest form of inter-process communication between UNIX, which exists in all UNIX implementations. For piping, there are a few things to know about this:1, it is half-duplex, that is, the data can only flow in one direction. While in some UNIX implementations, pipelines can be full-duplex. However, some settings are required for the system. In a Linux system, it is half-duplex.2, it has no name. So it can only be used between pro
The rendering pipeline is the entire process of OpenGL-rendered scenes and is the process of rendering the objects to the plane. OpenGL's rendering pipeline went through the traditional fixed pipeline (the steps in the rendering process are defined beforehand) to the current programmable way (using the shader implementation), which is mainly due to the developmen
When item is collected in the Spider, it is passed to item Pipeline, and some components perform the processing of the item in a certain order.Each item pipeline component (sometimes referred to as "item Pipeline") is a Python class that implements a simple method. They receive the item and perform some behavior through it, and also determine whether the item con
I will upload my new book "Write CPU by myself" (not published yet). Today is 15th articles. I try to write them every Thursday.
In the previous chapter, the original five-level pipeline structure of openmips is established, but only one Ori instruction is implemented. It will be gradually improved from this chapter. This chapter first discusses issues related to pipeline data, then modifies openmips to s
terms of continuous integration, we choose Jenkins. Jenkins is an open source software, with a number of excellent plug-ins, relying on these plugins, we can complete a number of cycles, tedious, complex tasks. For example, the ongoing release we share today, although Jenkins solves our tedious and complex cyclical operations, does not address our need to build builds in multiple environments. And this scenario is what Docker's strengths are. Through the pi
Understanding pipeline in Laravel appears many times during laravel startup. to understand the startup process and lifecycle of laravel, understanding pipeline is one of the key points. Pipeline is rarely explained on the Internet, so I should write it myself.
First, let's take a look at the call stack, that is, what laravel has done from a request to a response.
Example 4:/* interaction between parent and child processes: the parent process writes from parent process to the child process, and the child process writes from child process to the parent process */

This section is another way to learn about process communication: pipelines. A pipeline is a process that connects a stream of data to another process's channel, which typically connects the output of one process to the input of another process through a pipeline. The application of pipelines is often seen in shell commands, such as we want to list all files named "Test" under the current file: Ls-l | grep

Even if the graphic user interface is dominant today, console output still plays an important role in Java programs. The console is not only the default stack trace and error message output window for Java programs, but also a practical debugging tool (especially for those who are used to using println ). However, console windows have many limitations. For example, on Windows 9x, the DOS console can only accommodate 50 rows of out

Implementation conception of software development and standardized pipeline development
I recently saw a blog post discussing the topic of standardized pipeline development mode. However, this blog post only raised this question and did not respond.
This is actually a big problem. I have been engaged in software development for so many years, but I still haven't seen any domestic company actually do it. I h

The pipeline created by GStreamer does not need to be completely closed. There are several ways to send data to pipeline at any time, or to remove it from the pipeline. This tutorial shows you:
