The powerful sputation of stars:

I don't know how to understand it, it's easy to hurt people. The project owner's communication barriers, and when asking questions, he will always die. He just cares about his own content, and never listens to anything else. He always thinks that he can really escape and has insufficient ability.

To ask a question, just one sentence, or the project is unfamiliar, just a few lines of code, you can look at it again, or even a very impatient prompt, look at what is where and where, time and facts prove that it is still in the mother's womb? Waste of effort.

Project Optimization took a long time, and some code was not very understandable (maybe it was a breakthrough or optimization). The result was an impatient sentence: the code is not long, take a good look, the code is useless and can be deleted. ~~~ The beginning of the tragedy ..

I did not pay much attention to that piece of code. The time and effort proved that the breakthrough point was really there !!!

 

Just like this time, I am in a bid again (no way, new people + only me + but a single project + first attempt + lack of network resources + lack of official documents ),
