Background: Recently, the project has encountered the problem of thread synchronization. In addition, the logic is more complicated and some are not very rigorous. Is debugging a big problem? Two developers have been arranged to solve it, but there is no progress. The problem will drag on for a week. Still in a hurry.
Personally, I think: When dealing with this kind of problem, if you find that there is no progress after two days, you should focus on multiple experienced developers in the team, focus firepower, and get rid of the problem. When one person solves a problem, his thinking will often be broken. When two people look at a code, the thinking is not easy to break, and it is not easy to fall into a mindset. It's like throwing 10 grenades one by one is not as powerful as throwing 10 grenades or 5 all at once.
