Why do many programmers not change their clothes for months, because they are not doing anything? Why do many programmers not change their clothes for months, because they are not doing anything? Reply: people in the world do not care about appearance. The focus is different. They focus on completing the same thing, with high efficiency and code elegance. There is no need to cater to others' eyes. For me, jackets and things are casual. Underwear and close-fitting vests must be premium products.
Programmers do not need to deal with people every day to run their business. They mainly deal with machines. Beautiful code is better than gorgeous clothes to satisfy their hearts
This is why there are black spots. After reading "hackers and painters", you will know the answer. The programmer's focus is not on wearing, but on how to write interesting and COOL things. The programmer's world cannot be understood by programmers. Because they work on cold machines.
