C11: sleep for vs yield
While reviewing the code, std::this_thread::yield() suddenly popped into my view, a syntax sugar from C11 that I’d used quite a bit, but hadn’t noticed before.
Linux Server, Reset MySQL Password
I had an idle Tencent Cloud server that was expiring at the end of the year and I hadn’t planned to renew it. So, I decided to deploy a MySQL database for development purposes. When reinstalling the system, I wanted to save time and chose a third-party image provided by Tencent Cloud, which already had MySQL installed. I thought the system should include a Readme file or similar documentation explaining the password and deployment path.
Onomatopoeia of the Night
Here’s the English translation of the provided text: Within the vast system of Chinese characters, the character “命” (life/fate) is utterly unique; there isn’t even a single homophone. Perhaps this subtly suggests that each person’s life has only one opportunity, cannot be replicated, and cannot be relived. During leisure time, I browsed the rankings on Qidian Chinese
A Brief Overview of Automated Testing
The investment in testing for financial trading systems far exceeded that of other systems, with tedious test steps repeatedly executed and a low ROI. As projects and personnel changed, uncontrollable factors inevitably introduced, a common situation being the modification of a field output from Interface A impacting the results of Interface B. With each version release, risk also accumulated. Theoretical Knowledge How to Measure the Value of Automation? An automation testing ROI = (Manual Execution Time) * (Number of Runs) / (Development Cost + Maintenance Cost) Which Features Should Be Automated?
Why Do We Need to Learn a New Language?
Starting from my academic years, I’ve been working with C++ for over ten years. So, why do I need to learn other programming languages? Work experience: Lacking experience in elegant module design, C++ syntax is freeform. Learning other languages helps me guide the development of more elegant designs. I often use them when writing some tools. The design principles for low-level libraries and business modules are also becoming clearer.
Visual Studio Compilation Character Set [Converted]
C++ cross-platform development. Commonly encountered on Chinese operating systems: error C2001 - constant contains a newline character. Visual Studio cmake organizes the project compilation script, generating a temporary solution under the windows system for development. The reason for cross-platform compatibility is that the file encoding is chosen as utf-8. The cited reference provides a detailed explanation of the causes of the problem from first principles. Regarding encoding, MSVC has dedicated compilation options /source-charset and /execution-charset.
