No best, only better

During this period of time, I re-designed the coffee cashier system I previously wrote. In this process, I used a number of similar software on the Internet. In the design process of referring to others, I suddenly understood the truth ------ there is no better but better.
Software development is a relatively easy task to be copied and imitated. so don't be discouraged when you see other people's good works, because as long as you have the ability to have time, even if you copy 89, you can never leave 10, so if you design something better, so do not be proud, others can still copy 89.
Microsoft is an expert in this regard. He told people that although the current version is difficult to use, the next version will certainly be greatly improved, so we have always been looking forward to his next version. however, although he knows this well, there are also some mistakes, the Firefox browser gave him a lesson. More than 10 years ago, he relied on refactoring code to make ie surpass Netscape, but now, he has to face the powerful challenges of Firefox again.
Do not look at how strong others are, or how strong they are. Software development is always carried out with reference to the rules of this game. Always prepare to refactor the code to surpass others or cope with the challenges of others.
