Another look at the Glide image loading library from a memory optimization perspective

Front background As a commonly used image loading framework, Glide has a lot of memory optimizations at the framework level. However, as an image framework, ensuring correctness must be the first priority. Therefore, some additional optimizations can be made in appropriate scenarios at the application layer. , of course you need to understand the problems […]

From the perspective of memory management, an illustration of variable and parameter transfer in Python language

From the perspective of memory management, an illustration of the transfer of variables and parameters in Python language Overview From a memory management perspective, variable and parameter passing in Python has some characteristics: ☆ Variables are references to objects: In Python, variables are actually references to objects, not the objects themselves. When you assign a […]

[Docker] Explore Docker’s bridge network from the perspective of namespace and routing

Bridged networking is Docker’s default networking mode. In a bridged network, Docker creates a virtual network interface for each container and assigns the container an IP address. Containers can communicate with the host and other containers through bridged networks, and can also expose ports for external access. Principle of communication between containers First we create […]

UGUI – Analyzing the UGUI framework from the perspective of Button (Part 2)

In the last article, we stopped at the search for PointerEventData data and traced it back to the PorcessMousePress() method. Finally, we found that the source of the data structure was constructed in the ProcessMouseEvent(int id) function. The source code is as follows 1Preliminary structure of PointerEventData data //StandaloneInputModule| void ProcessMouseEvent(int id) var mouseData = […]

Analysis from the source code perspective: Why an exception is reported when deleting data in a Java loop

1. Analysis from the source code perspective: Why an exception is reported when deleting data in a Java loop I believe everyone has more or less known that deleting data in enhanced for in Java will throw: java.util.ConcurrentModificationException exception, For example: The program is as follows: public class RmTest {<!– –> public static void main(String[] […]

Looking at the life of interruption from the perspective of software and hardware interaction

Perface Hi ALL! Recently, I have been locating a problem about interrupts. In the past, these issues were treated separately. It was either how the software designed the interrupts or how the hardware designed the interrupts. I just took this opportunity to sort out the knowledge about interruption from the perspective of software and hardware […]

The principle of UI thread from the perspective of Android Handler/Looper

Overview The Handler/Looper mechanism is a non-important and basic mechanism of the Android system. This mechanism is often used for reference even when developing application frameworks on rtos or linux operating systems. Through this mechanism, a thread can process events in a loop, and the event processing logic is in the Handler’s handleMessage. This article […]
