[STM32] Several message reception filtering modes for STM32 CANFD peripherals
In Controller Area Network (CAN) systems, correctly configuring message filters is critical to effectively manage network communications. Especially when using the Flexible Data-rate Controller Area Network (FDCAN), choosing the appropriate filter type can greatly improve network efficiency and message processing speed. The CAN peripheral of the STM32G47x chip has the following reception message filtering methods: […]
SpringBoot distributed verification code login solution
Foreword In order to prevent the verification system from being violently cracked, many systems have added verification code verification. The more common one is the picture QR code. The safer one in the industry is the SMS verification code. Of course, there are also some puzzle verification codes and QR codes with artificial intelligence. Wait, […]

Currently, the most commonly used one is Redis. Install dependencies Like the previous mysql, the most commonly used dependency of redis is redis npm install redis Depend on the […]
Replace for loops and make Python code more pythonic!
Text | Parson Sauce Source: Python Technology Why challenge yourself not to write a for loop in your code? Because this forces you to learn to use more advanced and more idiomatic syntax or libraries. The article uses python as an example to talk about a lot of syntax that everyone has seen in other […]

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 […]
TrOCR model fine-tuning [Transformer-based optical character recognition]
The TrOCR (Transformer-based Optical Character Recognition) model is one of the best performing OCR models. In our previous article we analyzed their performance on single lines of printed and handwritten text. However, like any other deep learning model, they have their limitations. TrOCR doesn’t perform well with curved text out of the box. This article […]
