The essence of programming: discovering and solving problems

-- Reading the beauty of Programming

 

I got this book from Dangdang today, but it is a pity that it is worn out. This is the first time I got a worn book from Dangdang. I can't help it. Who can do it.

I roughly flipped through and looked at the "How to Use CPU usage to stabilize at 50%" and "the handsome question in Chinese chess ".

I feel pretty good. I don't blame a friend for saying, "This book is just a scam, but it's better to do the Primary School Application Questions." This still makes some sense, but if I let the primary school students see these two problems, it is estimated that the pupil will go crazy.

I remembered my primary school time as a "superior student". At that time, I had to make up classes or make up classes every day. I remember that I was very popular with a book called "Application Questions, I did it from the beginning to the end, but it was a pity that the middle school had been ruined, so that mathematics could not keep up. This book reminds me of many classic questions I have learned before.

When I graduated, lkz once said this to me: "You say that we are a computer graduate of this level. What can we do in addition to database storage in the future ", I think I can finally answer this sentence today. Even if I store a database, it is a database that is stored and processed in a faster, better, and more stable manner based on the business logic."

But after all, it is unwilling to "store the Database" for a lifetime. algorithms should be the soul of the program. A programmer with poor mathematics will always be able to be a code farmer. I am glad that I am a programmer. After all, I need to use a foreign language in my work, I need mathematics, and I need the knowledge I have learned in Computer Science. Some of my friends, I was a good student at school and tried to learn mathematics and physics, but I never needed to use it again at work.

Learning is a sad thing.

Let's look back at this book. In fact, the content of this book is still odd. Will there be a business that lets you "have to keep the CPU usage at 50%? Of course not. :) For those who only draw images from the gourd tree, let's stay away from this book. The essence of this question is, through this question, what can you think of and what else you can know. It's as if we are learning Assembly. A programmer knows assembly. It's like a British gender who knows Latin. He may rarely use Latin, but Latin exercises his thinking and memory, it can even be said that Latin is a symbol of his "aristocratic" identity.

Discovering and solving problems is the essence of programming.

This book gives me a sense of simplicity ......
