So far, the server programs we’ve discussed only listen on one port. But in practical applications, there are many server programs that can monitor multiple ports at the same time, such as the super service inetd and the android debugging service adbd. From the parameters of the bind system call, A socket can only be […]

The router realizes the first-level menu, and the second-level menu is not in the same interface, but realizes simultaneous highlighting
Effect image: Brief description: Switch the second interface, and the side menu of the first interface will also be highlighted. Here is an idea for everyone. Using my code directly may cause problems, as long as you look at The processing of the last js code. The default-active of both interfaces is the current route. […]
ffmpeg multi-channel simultaneous streaming
1. Common usage methods of ffmpeg 1.1 Use FFMPEG command for file segmentation 1.2 Conversion format 1.3 Push configuration Method 1: ngnix (not recommended, streaming is not easy to use) Method 2: srs (strongly recommended) 1.4 Check whether nginx startup is successful 2. ffmpeg streaming –>ngnix Single channel streaming Multiple (greater than two) channels push […]
STM32 multi-channel ADC simultaneous scanning sampling
Background In the actual application of the project, there is a need to use multiple ADCs for simultaneous sampling. Here, STM32 ADC is selected for simultaneous sampling of multiple ADCs. Here is a brief description of the configuration process and usage steps. Schematic As shown in the figure below, using four ADC inputs ADC_Voltage -> […]
STM32 independent key scanning, support simultaneous press, long press, quick key value
Background There is a project that uses 8 independent buttons in practical applications, and each button is assigned a different function. In actual use, special button operations are often required, for example: press and hold the button for 10s, press and hold the button for 5s, or Long press needs to have quick button value […]
Principle of simultaneous compression transform based on wavelet transform and Matlab code
Principle of synchronous compression transformation As a powerful tool for dealing with non-stationary signals, time-frequency analysis jointly characterizes signals in time domain and frequency domain, which is a binary function of time and frequency. Traditional time-frequency analysis tools are mainly divided into linear methods and quadratic methods. The linear method is restricted by Heisenberg’s uncertainty […]
Simulate simultaneous concurrent requests in java
Sometimes it is necessary to test the concurrency performance of a certain function, and it is most convenient to develop a concurrent request without resorting to other tools. To simulate concurrent requests in java, just open a few more threads and initiate requests. However, this kind of request generally has a sequence of startups, and […]
Explore the parallelism of GPU simultaneous rendering and general computing
10 years ago, with the release of CUDA and OpenCL, GPGPU was really popular. Nowadays, many companies use GPGPU as a computing tool for mining and machine learning. Ever since, there have been many claims that GPUs will soon replace CPUs! So are modern GPGPUs so powerful that they can replace CPUs? This article will […]
Element-UI + SpringBoot + FormData realize simultaneous upload of multiple files
1. Requirements analysis Drag Email files, Word files, and PDF files to the file upload list, and then click Confirm Translation to upload all files at the same time, and receive them at the same time at the backend, and then return the address of the translated file to the frontend. Encountered problems: Element-UI components […]
