Network Programming (5) IO Multiplexing — epoll
1. Concept The full name of epoll is eventpoll, a notification mechanism based on event triggering. When the file descriptor read buffer is not empty, the read event is triggered. When the file descriptor write buffer is writable, the write event is triggered. 2. Principle The core data structure of epoll is: a red-black tree […]

Network (2) VLAN technology and network layer analysis
VLAN technology and applications 1 Broadcast Domain The broadcast domain refers to the range that receives the same broadcast message. Any device in this range sends a broadcast and all other devices can receive it. By default, all interfaces of the switch belong to the same broadcast domain 2 VLAN Overview VLAN, Virtual LAN (Virtual […]
Solution to “Python3.12pip network installation library file error, ssl module is unavailable”
Solution to “Python3.12pip network installation library file error, ssl module is unavailable” 1. Install the new version of openssl3.1.4 2. Install Python3.12.0 The Python version needs to match the openssl version. In versions after Python 3.7, the dependent openssl must be a version after 1.1.1 or 1.0.2, and the openssl1.0.2k installed in CentOS7 cannot meet […]

Deep Neural Network (DNN) is an artificial neural network characterized by having multiple layers of neurons
Deep Neural Network (DNN) is an artificial neural network, which is characterized by having multiple layers of neurons, which can better handle complex nonlinear problems. In Java, we can use open source libraries such as Deeplearning4j (DL4J) to implement deep neural networks. In DL4J, a basic deep neural network consists of multiple layers, each containing […]
“Network Security” How to build a MySQL malicious server to read files?
Foreword Note: This article does not involve research on MySQL protocol messages. It only explains the principles and does some demonstrations. Although the threshold for direct use of building a MySQL malicious server to read files is relatively high, I personally feel that it is relatively new because I saw a relatively new way of […]
