  About C++ comma operator precedence

When learning programming language, we will always have one topic about the operator precedence. Since there are many operators can be used in one expression, there should be some rules regarding which operation can happen first so that the compiler or interpreter can handle them correctly. One rule of programming with expression is using as much as brackets as you can to avoid unexpected results. Here we refer one problem we see online about the comma operator in C++. The following program has ...

  Applying Large Language Models (LLMs) to Solve Cybersecurity Questions

In this document, we will introduce some test, experiment and analysis conclusion about applying Large Language Models (LLMs) to solve cybersecurity questions. Introduction Large Language Models (LLMs) are increasingly used in education and research for tasks such as analyzing program code error logs, help summarize papers and improving reports. In this project, we aim to evaluate the effectiveness of LLMs in solving cybersecurity-related questions, such as Capture The Flag (CTF) challenges, ...

  About browser event

First look at following codes: var $ = KISSY.all; $(‘a’).on(‘click’,function(e){ doSomeThing();//This function seems very famous e.halt(); }); The above codes seem complete the work we want them. The browser will not redirect us to the link in href, but is there some issue with the codes above? Before explaining what's wrong with the above codes, we first need to understand some concepts. Browser default behavior When we click a link, the browser will redirect us to anoth...

  Do Not Be Misled by ‘Build an App in 5 Minutes’: In-Depth Practice with Cursor

In August this year, I tried out Cursor and was thoroughly impressed, prompting me to write an introductory article about it. Soon after, I transitioned my daily work environment entirely from GitHub Copilot + JetBrains to the paid version of Cursor. After several months of use, it has felt incredibly smooth. While using it myself, I’ve often recommended Cursor to colleagues and friends. However, many of them still have questions, such as: What advantages does it have over native ChatGPT ...
