Starting this week, Xiaoquan officially launches the “GitHub Project Selection Weekly” plan, which selects some fun, interesting, practical, and advanced open source projects that Xiaoquan has encountered or recommended by big players in the industry, and shares them in the form of weekly articles. For everyone to watch and learn, hoping to learn and make […]

html+jquery circular gradient progress bar
Special point, circular progress bar, the color of the progress bar changes with the progress, from green to yellow, and finally to red. Mainly applicable: large screen display. html <canvas id=”canvas” width=”160″ height=”170″>cpu</canvas> js call Locate the position of the corresponding div const canvas = $(‘.div’).find(‘#canvas’)[0]; updateProgress(canvas, 55, “CPU”); method // Function to update progress […]
C language stack and queue are a big gift package [stack implements queue, queue implements stack, and comes with a circular queue, ah ah ah ah]
Foreword [must read] Anyone who has learned stacks and queues is welcome to visit. . . [Baozi who has not learned it may not understand it well, because there are few comments and many implementations. [Mainly because of laziness (roll 0) 1. Implementation of stack Let’s build a stack Because the stack only operates on […]
Using Hystrix to implement circuit breakers in Spring Cloud
1. Why use Hystrix When calling between multiple microservices, assume that microservice A calls microservice B and microservice C, and microservice B and microservice C are calling other microservices. This is the so-called “fan-out”. If the call response time of a certain microservice on the fan-out link is too long or is unavailable, the call […]
10. Circuit synthesis-wideband matching circuit design method based on simplified real frequency
10. Circuit synthesis-wideband matching circuit design method based on simplified real frequency Chapters 1-9 in the Overview of Network Synthesis and Simplified Real Frequency Theory Learning introduced some basic concepts and experimental methods of SRFT, and finally came to another ultimate use of SRFT, the design of broadband matching circuits. 1. Some previous reviews and […]
Spring third-level cache solves circular dependencies
Circular dependencies @Component public class A { @Autowired private B b; public B getB() { return b; } public void setB(B b) { this.b = b; } } @Component public class B { @Autowired private A a; public A getA() { return a; } public void setA(A a) { this.a = a; } } When […]
9. Circuit synthesis-microstrip circuit design based on arbitrary amplitude-frequency response of simplified real frequency
9. Circuit synthesis-microstrip circuit design based on arbitrary amplitude-frequency response of simplified real frequency Chapters 1-8 in the Overview of Network Synthesis and Simplified Real Frequency Theory Learning introduced some basic concepts and experimental methods of SRFT, and finally reached the ultimate use of SRFT, which is to directly synthesize a microstrip circuit given any […]
Circular queue (C language)
1.Definition: A Circular Queue, also known as a circular queue or circular buffer, is a queue data structure that has a fixed-size buffer that allows elements to be inserted and deleted at the front and back of the queue. Unlike ordinary queues, circular queues can avoid the problem of wasted storage space because when the […]
[Interesting algorithm] Circuit wiring problems (including source code)
Requirements Circuit layout problems often involve connecting a set of electronic components (such as resistors, capacitors, transistors, etc.) on a given circuit board to meet specific circuit connection requirements. This is a typical graph theory problem and is usually solved using graph theory algorithms. Implementation C++ The following is a simple C++ code example that […]
Downgrade circuit breaker: How to shield the impact of non-core system failures?
Table of Contents Preface 1. What is circuit breaker? 2. Service downgrade 3. How avalanches occur 4. Use of hystrix 5. How to implement the downgrade mechanism Summarize Foreword Amidst the huge traffic of “Double Eleven”, there were several short-term service unavailability during the product promotion process, which caused a bad experience for some users.
