Two JS handwriting questions a day—manually implement the call, apply, and bind functions in JS
Functions in JavaScript are first-class citizens and can be passed around and used like ordinary variables. This flexibility allows functions to be used in various scenarios, such as invocation of object methods, creation of constructors, and prototypal inheritance. During the use of functions, call, apply, bind are some of the more commonly used methods in […]

Netty calls System.exit(n) to exit the application after a certain number of retries (2)
============================== System.exit() method ================= ============== Prototype: System.exit(int status) Its function is mainly to call Runtime.getRuntime().exit(status); The function is to terminate the currently running Java virtual machine. This status indicates the exit status code, and non-zero indicates abnormal termination. (You can return a call return code to the caller of other processes to adopt different strategies […]
lwIP update note 07: TCP control block application failure can be detected
Starting from lwIP-2.0.0, TCP control block application failure can be detected. This update applies to TCP_PCB in the monitoring state in the TCP server mode. If it receives the SYN synchronization flag sent by the client, it means that a client is requesting to establish a connection. lwIP will apply for a TCP_PCB for this […]

The file_operations structure of the interactive mode of linux application and driver
Why does linux user mode need to drive and control hardware 1. Linux needs to provide users with unified operation functions, such as read(), write() and other API functions, so that people who write user mode code do not need to have a deep understanding of the hardware. 2. Linux needs to ensure the stability […]
Talking about delegated attribute 3: behind and application of delegate
Through the discussion and learning of the previous two articles, we have a clear understanding of the delegation of attributes. Let’s take a look at the actual application scenarios of delegated attributes today. Behind property delegation Before introducing the application scenario, let’s look back at the backside of property delegation and explore its implementation principle. […]
