Arduino implements 32-frequency audio spectrum display
This project uses Arduino and four dot matrix screens to realize the visual display of 32-frequency audio (music) spectrum. A lot of space is spent here to explain its principles (it may be slightly difficult for beginners to understand), and a complete schematic diagram and source code are provided. If you like to watch music […]
<1>, C++ implements multi-thread synchronization processing: controlling the output sequence of ABC, outputting 10 groups, mutex+condition_variable
Table of Contents need: analyze: Some code implementation: 1. Operations implemented using only flag bits: 2. For greater security, the mutex lock code is added: 3. Use it with unique_lock to make the code safer Four: Use guard lock lock_guard to work with it 5. You can also use condition variables to process, which will […]
OneAPI Intel Experimental Matrix Multiplication Implementation
Introduction to OneAPI oneAPI is a cross-platform, open and unified programming model designed to simplify and accelerate heterogeneous computing. It is led by Intel Corporation and supported by a wide range of partners. The goal of oneAPI is to provide a unified programming environment that enables developers to write high-performance applications on different hardware architectures, […]
Source code and analysis of specific implementation of Set interface
The author was asked this question when participating in an interview at a bank. Have you ever understood the implementation principle of HashSet? Since this small point is only used normally, but the source code has never been seen, so I can only be “short of money”. (Take openjdk-19 as an example) Source code First […]

DevChat’s first exploration into the implementation of the RBAC model
Today we will try a programming assistant DevChat to see if it can improve our daily programming efficiency. As a programming assistant, let’s take a look at some of its differences and features with products in the same field as Copilot and CodeWhisperer. Set a small goal, implement a simple RBAC model through DevChat, and […]
