<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 […]

Application of stage, job, task and condition in YAML Introduction Resource preparation structural relationship Code writing (task) Define variables within task task condition gets variable value task code explanation Test task code Code writing (job) job variable definition Get job variable value job condition job code explanation Test job code Code writing (stage) stage code […]

python selenium clicks a series of buttons in the table and outputs the pop-up content to csv

A practical example of python selenium, heavier than the demo, but not too complicated. The trick is summarized as follows: The address of the latest chromedriver is https://googlechromelabs.github.io/chrome-for-testing. This is very important, otherwise you will have to deal with annoying problems such as automatic chrome updates. Many download sources are a bit outdated. Use options […]

Java input and output(4)

Java input and output (4) 1. RandomAccessFile class The RandomAccessFile class is not a stream, but it has the function of reading and writing file data. It can randomly start reading and writing data from any position in the file. The RandomAccessFile class can open a file with specified operation permissions (such as read-only, write-only, […]

In order to retaliate confidently, I wrote a log aspect output interface input and output parameters.

1.Background In the process of daily troubleshooting, we know that incorrect input parameters are one of the common reasons for interface call failure. Especially the callback interface and openAPI interface provided for third-party calls. Since the level of third-party developers cannot be guaranteed, problems often arise. I repeatedly come to you to ask why it […]

Based on the snow melt optimization algorithm SAO published in June 2023, the LSSVM is optimized for single-input single-output time series fitting prediction modeling.
