Java implements a set of process management and flow ideas (pseudo workflow)A management project is required to implement a set of process management, such as the application approval process for asking for leave. After referring to a lot of information and discussing with colleagues, A self-implemented process management is achieved. The following provides my design ideas. After knowing the ideas, it is much easier to implement them. First, I designe
Serial Communication Flow Control
In serial communication processing, we often see the two options, namely, RTS/CTS and Xon/xoff, which are two traffic control options. Currently, traffic control is mainly used in modem data communication, but for general RS-232 programming, understanding this knowledge is good. so what is the role of Stream Control in serial communication and how to apply it in the preparation of serial communication programs? Here
We've created websites and software to show people information that can be anything: a company's product list, vacation photos, or instant messages from friends, and at this point, more information is presented to you than ever before in history.
All this information has many positive effects, but it also poses challenges. " The cost of information is obvious, it consumes the attention of the receiver of the message ... The richness of information brings a scarcity of attention "(Simon 1971) Wh

Streaming Diagram (DFD)The data flow diagram, or DFD, is a tool used in the SA method to represent the logical model of the system, which graphically depicts the process of flowing and processing in the system, because it only reflects the logic functions that the system must complete, so it is a functional model.The figure below is a data
Sorrow needs to endure, happiness needs to be sharedI couldn't stand the performance of the Linux stack multiple times perf, but it was so powerful that I couldn't give it up, I wanted to implement a fast flow meter myself, but I had to abandon many of the features that depended on conntrack, like state Match,linux Nat and so on, admittedly, I've complained too much about NAT, but it's not that many people are using it anyway.Once, I have done a connt
Git Glow Simple Introduction to Git-flow, is a tool that is a specification
Git flow is a model of the Organization's software development activities built on GIT and is a software development best practice built on top of git. Git flow is a set of behavior specifications and a tool for simplifying some git operations when using Git for source control.
git best practices in the team-how to use git Flow correctlyWe've been switching from SVN to git for years, and now almost all of the projects are managed using GitHub, and this article tells you why Git is used and how it's used correctly in your team.Advantages of GitThere are many advantages to git, but here are just a few points that I think are very prominent.
Because it is distributed, all local libraries contain all the contents of the
Data Flow Graph (conversion)
Data Flow Diagram (DFD)A Data Flow Diagram (DFD) is a tool used in the SA method to represent the system logic model. It graphically depicts the process of data flow and processing in the system, because it only reflects the logical functions required by the system, it is a function model.I
Introduction
The rain flow counting method was introduced in the 1950s by the British two engineers M.matsuishi and T.endo. The main function of this method is to simplify the measured load process into several load cycles, which is used for estimating fatigue life and compiling fatigue test load spectrum. Based on the two-parameter method, the dynamic strength (amplitude) and static strength (mean) of two variables are considered, which conform to t

Activity diagram:
The UML activity diagram records the logic of a single operation or method, a single user case, or a single business flow. In many ways,Activity diagramIt is the object-oriented equivalent of a flowchart and a data flowchart (DFD) in structured development. To create a UML activity diagram, you must perform th
First, the maximum flow problemProblem statement: Given a picture (n nodes, M-edge), each edge has a capacity, now need to transport some items from the node s (known as the source point) to the node T (called the sink point), can be transferred from other nodes, to find the maximum transport volume.Before introducing the solution to the maximum flow problem, we introduce several concepts: reverse arc , res
Data Flow tasks are a core task in SSIs. It is estimated that most ETL packages are inseparable from data flow tasks. So we also learned from data flow tasks.
A Data Flow task consists of three types of data flow components: source, conversion, and target. Where:

I. Introduction of AzkabanAs an open-source dispatch system, Azkaban is widely used in big data. It mainly consists of three parts: Azkaban Webserver, Azkaban Executor, and DB.Figure 1 Azkaban ArchitectureFigure 1 shows the basic architecture of Azkaban: webserver is mainly responsible for authorization, project management, job shedding, etc. executor is mainly responsible for the job flow/job execution and the collection of execution logs, etc. mysql
What is network streaming?Don't worry, we'll take it slow.First, let's look at the maximum flow 1. backgroundThe maximum passing capacity (capacity) of each edge in a piping network is limited, and the actual traffic does not exceed the capacity. Maximum flow problem (maximum flow problem), a combinatorial optimization problem, is to discuss how to make full use

(stream) is a channel that communicates data.The input of the Java program to the data, and the output operation is carried out in a "stream" manner. A variety of "stream" classes are available in the JDK to get different kinds of data5. Classification of streams5.1 Direction of Flow:
Input stream: The stream from which the program can read data
Output stream: A stream to which a program can write data
