In modern software development, the ability to rapidly build and deploy backend services is a goal every developer strives for. PocketBase emerges as a powerful yet simple solution to this goal. This blog post will guide you through PocketBase’s background, features, and how to get started using it to build backend services. What is PocketBase? PocketBase is an open-source backend framework written in Go, released by Michael Hladky in 2022. It aims to help developers quickly build fully functional backend services while maintaining a lightweight and efficient system. PocketBase integrates various common features, such as user authentication, file storage, real-time…

Recently, my friend Alice encountered an intriguing problem with her Python project. She noticed that the same Python code utilized a different number of CPU threads when run in different computing environments. Puzzled by this discrepancy, she reached out to me to explore the underlying reasons behind this phenomenon. The Influence of Operating Systems and Python Interpreter Versions First, we need to understand the differences in how Python interpreters and operating systems handle multithreading. Different versions of the Python interpreter can have varying behaviors when dealing with multithreading. For example, there are significant differences between Python 2.x and Python 3.x.…

In the world of operations, Kubernetes is a name that resonates deeply. This powerful container orchestration platform helps us manage and deploy complex microservices applications, simplifying many tasks that used to require manual handling. However, Kubernetes’ powerful capabilities can sometimes bring complexity, especially when it comes to managing external access to internal services. This is a story about Ingress, a gem in the Kubernetes ecosystem. The Challenge of External Access Imagine you’ve been working in the cloud computing and operations field for years. Your company has just launched a microservices architecture based on Kubernetes, deploying dozens of services, each responsible…

In this era of rapid digital advancement, protecting our online data has become increasingly important. Whether we’re shopping online, doing bank transactions, or simply logging into social media accounts, we want to ensure that our information doesn’t fall into the wrong hands. So, what exactly is HTTPS, that common set of letters we often see in URLs, and how does it protect our data? Today, let me explain how HTTPS works through a simple story. Bob’s Online Shopping Adventure Let’s imagine one day, Bob decides to purchase a smartwatch he’s been eyeing for a while. He opens his browser, types…

As a developer, I’ve always been fascinated by the flexibility and power of microservices architecture. This approach breaks down a monolithic application into multiple small, independent services, each focusing on a specific task. In this article, I will share some of my experiences and insights, guiding you through what microservices are and how microservices work. 1. Container Technology: The Foundation of Microservices When I first delved into microservices, container technology was the initial area I explored in depth. Containerization technologies like Docker fundamentally changed my perspective on software deployment. Docker allows us to package applications and their dependencies into portable…

As an individual developer and tech blogger, I frequently encounter projects requiring real-time data communication. Among these projects, one of the most common needs is for the server to push data to the client in real-time. In modern web development, there are two main technological choices for this requirement: Server-Sent Events (SSE) and WebSocket. The choice between these technologies not only impacts the architectural design of the project but also directly relates to user experience and the efficient use of server resources. Today, I aim to delve into the characteristics, applicable scenarios, and trade-offs of these two technologies in practical…

Introduction:The “Error: Gradle – Lint found fatal errors while assembling a release target” message is generated by the Android lint tool, which checks your Android project for potential issues. This error typically occurs when there are critical issues in your project that need to be addressed before you can build a release version. In this article, we will analyze the possible causes of this error and provide solutions to resolve it. Understanding the Error:The error message indicates that the Android lint tool has detected one or more critical issues in your project during the release build process. These issues could…

java.lang.NullPointerException: Attempt to invoke virtual method ‘int android.graphics.Bitmap.getWidth()

Error creating bean with name ‘org.springframework.aop.config.internalAutoProxyCreator’: Initialization of bean failed; nested exception is java.lang.AbstractMethodError: org.springframework.aop.framework.autoproxy.AbstractAdvisorAutoProxyCreator The error message “Error creating bean with name ‘org.springframework.aop.config.internalAutoProxyCreator’: Initialization of bean failed; nested exception is java.lang.AbstractMethodError: org.springframework.aop.framework.autoproxy.AbstractAdvisorAutoProxyCreator” typically occurs when working with the Spring Framework in a Java application. This error indicates that there was an issue during the initialization of a bean related to Spring’s AOP (Aspect-Oriented Programming) configuration. Here’s an analysis of the error and a solution from the perspective of an individual developer: Error Explanation: The error message suggests that the bean named ‘org.springframework.aop.config.internalAutoProxyCreator’ encountered an initialization failure. The root cause…

The error message “Exception in thread ‘main’ org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type” typically occurs when working with the Spring Framework in a Java application. This error indicates that Spring couldn’t find a bean that matches the requested type during the application’s context initialization. Here’s an analysis of the error and a solution from the perspective of an individual developer: Error Explanation: The error message indicates that Spring’s application context couldn’t find a bean of the specified type. Spring uses a container to manage and wire beans, and this error occurs when it can’t locate a bean of the specified…
