Synchronization experiment of operating system processes

1. Experimental purpose (1) Master the basic concepts and properties of processes and threads; (2) Implement multi-threaded ticketing: simulate multiple ticketing windows (there are 2 windows here), and each window can sell tickets at the same time. Through multi-threading, ticketing operations can be performed concurrently to ensure thread safety; (3) Provide user interface: Create a […]

RuntimeError: Sizes of tensors must match except in dimension 1. Expected size 58 but got size 57 fo

An error occurred: When using yolo v5n for network training, the input size used is 900*900. When connecting the Feature Map of the 11th layer and the 6th layer at the 12th layer Concat, there is a problem of different dimensions. After running, the following error message appears: RuntimeError: Sizes of tensors must match except […]

ADC experiment (internal temperature sensor experiment) (photosensitive sensor experiment)

Introduction to Internal Temperature Sensor STM32 has an internal temperature sensor that can be used to measure the temperature of the CPU and its surroundings (the internal temperature sensor is more suitable for detecting temperature changes. When precise temperature measurement is required, an external sensor should be used). For STM32F103, the temperature sensor is internally […]

Vue uses websocket to implement real-time data push and publish, subscribe and reconnect single sign-on functions.

Requirements: Use websocket to implement publishing, subscribing, network disconnection and reconnection, and account squeezing after single sign-in without using plug-ins. 1. Single sign-on (only one of the same account is online at the same time, multiple user logins are prohibited) Implementation: After the user logs in, the token token is obtained and stored locally. It […]

Springboot2.x integrated lettuce connection redis cluster reports timeout exception Command timed out after 6 second(s)

Original/Zhu Jiqian Background: Recently, I was doing a stress test on a newly developed Springboot system. I found that when I first started the stress test, I could access data from the redis cluster normally. However, after a few minutes of pause, and then when I continued to use jmeter to perform the stress test, […]

Experimental equipment *MCU experiment box *CH451 display module *Temperature acquisition module (at the lower left of the SWITCH module area of […]

BGP route reflector experiment example

1. Understanding route reflectors: To ensure connectivity between IBGP peers, a full connection relationship needs to be established between IBGP peers. Assuming that there are n devices within an AS, the number of IBGP connections established is n(n-1)/2. When there are a large number of devices, the device configuration will be very complicated, and the […]

Flink deployment series This section introduces the basic content related to the deployment and configuration of Flink. 2. Flink basic series This part introduces the basic parts of Flink, such as terminology, […]

[Java] Timing tasks – Timer/TimerTask source code principle analysis

1. Background and usage When implementing various server-side systems on a daily basis, we will definitely have the need for some scheduled tasks. For example, automatic reminders for meetings half an hour in advance, scheduled/periodic execution of asynchronous tasks, etc. So how to implement such a scheduled task system? The Timer class provided by Java […]
