Now I have an idea, that is, I hope to be able to remotely connect to my development board through the external network. Here we need to use a technology, intranet penetration. Intranet penetration is a technology that allows devices in the internal network to be accessed through the external network. In the linux system, […]

No framework, just use numpy to write a wonderful chapter of DNN (Deep Neural Networks)
1. Overview A Logistics Regression can be thought of as a simple neural network consisting of only one hidden layer (Hidden Layer) (as shown in the figure below). However, Logistic Regression is often very sensitive to outliers, and it is difficult to deal with polyphenols. Therefore, people were inspired by human brain nerves and established […]
03 | Serialization: How are objects transmitted over the network?
The previous lecture explained how to design an extensible and backward-compatible protocol in the RPC framework. The key point is to make good use of the extension fields in the Header and the extension fields in the Payload to achieve backward compatibility through the extension fields. So following the key point of the previous lecture, […]
Discuss in detail the difference between the sliding window algorithm and the KMP algorithm and the scenarios in which they are used.
What is the sliding window algorithm The sliding window algorithm is an algorithm for solving subarray (or substring) problems within an array (or string). The algorithm works by maintaining a fixed-size window (usually two pointers) that slides over the array to find subarrays that match specific criteria. The basic idea of the algorithm is to […]
Stm32_Standard library_18_Serial port & Bluetooth module_Communication between mobile phone and Bluetooth module_Control LED light on and off
Control the LED lights on and off by inputting LED_ON and LED_OFF respectively wiring: The positive electrode of the LED is connected to positive electricity, and the negative electrode is connected to GPIOA_Pin1 Bluetooth module TXD is connected to GPIOA_Pin3, VCC is connected to positive power, and GND is connected to negative power. Note: USART2 […]
The principles of Go language coroutines and the relationship between coroutines and threads! (Very important)
The coroutine of Go language is something unique compared to other languages, and it is also very important. Many times we want to understand its underlying principles, but cannot find suitable knowledge points on the Internet. For example, if you ask GPT, he will answer you like this : Coroutines and threads are both technologies […]

Campus network web page login version updated | Attached code
Since I wrote the campus network software last time, I want to optimize and modify it in depth. Optimized content: 1. If there is a problem with the browser, it will report an error directly, but now it is all under control. 2. After logging in to the browser, click the cross and it will […]

18NAT network address translation
1. NAT Overview 1. Foreword With the development of the Internet and the increase in network applications, limited IPv4 public addresses have become a bottleneck restricting network development. To solve this problem, NAT (Network Address Translation) technology came into being. NAT technology is mainly used to enable hosts in the internal network to access external […]
