There are too many softwares required for EDA courses. I am afraid that my memory will be fuzzy when I use them in the future, so I decided to simply write a (very detailed) process of creating a new project and simulation. This is also my first blog, maybe There are many problems, please point […]

C++ uses boost to implement an asynchronous thread pool with return values and input parameters
Preface Thread pools have some advantages over simple multi-threading: 1. The thread pool will automatically allocate work to an idle worker thread for execution, which is better than multi-thread execution in batches; 2. The thread pool only needs to be created once. The creation and destruction of multiple threads when used multiple times will cause […]
Weird trick, CompletableFuture asynchronous multi-threading is really elegant
An example reviewing Future In some business scenarios, we need to use multi-threads to execute tasks asynchronously to speed up task execution. JDK5 adds a new Future interface, which is used to describe the results of an asynchronous calculation. Although Future and related usage methods provide the ability to execute tasks asynchronously, it is very […]
Simulating the Task mechanism in .net: exploring the mysteries of asynchronous programming
Using Task in .net makes it easy to write asynchronous programs. In order to better understand Task and its scheduling mechanism, let’s simulate the implementation of Task in order to understand: What is Task How tasks are scheduled Basic Task simulation implementation Start with the most basic Task usage Task.Run(Action action) The function of this […]

Promise asynchronous processing method
A synchronous statement means that subsequent statements will not be executed until the execution of the statement is completed. An asynchronous statement means that after execution, the js engine will generate an asynchronous object. Mina’s statement will not wait for the asynchronous object to complete execution, but will be executed directly. Basically all operations of […]
