Six programming insights in these five years!

Preface

Before touching programming , I always think it's mysterious , It's awesome . Whenever there is a new system , When the new software comes out , Always want to rush ahead , then down Come down and experience .

Later joined the army of programmers , I found that programming is not as beautiful as I thought , Often have to face It can't be done The needs of , and An endless pot , It's really a bitter Coding history .

For all that , Our job is to inject... Into the machine soul , It's still very tall . But many times I have to face some cruel reality , Let's talk about the programming experience in recent years ！

1、 bug It can't be repaired

I wonder if you ape friends have such experience ： Whenever Friday approaches work , Tests always throw you a lot of bug The repair order .

And just when you think all bug When we're done , When you go back to the previous interface , Suddenly found that , It's fucking abnormal again .

It feels like pressing a gourd , Get up a ladle , Thought it was over , I found that I just thought .

Then why can't it be repaired all the time ？ On the one hand, because of the program, it is like a precision mechanical watch , Many places are related .

When you want to change a place , We often have to consider all its connection points , Kind of like depth first traversal . As one can imagine , Once the system is complex , Most of the time, we can only take one step at a time .

On the other hand, as long as our system is still used by users , Then there will be changes , Especially for the Internet industry with increasing demand in three days and two days , This is even more common .

With such a high frequency of changes , The best designed system can't stand the toss . It's like a fast-moving sports car , I always want to change parts for it .

So let's look at those mature open source frameworks , Each has its own release plan , And they are all the ones that are separated by a few months .

As one can imagine ： How important it is to reduce demand ！

2、if else It's our daily coding mode

Imagine , If not if…else What about our program ？ Yes , Everything is mixed together , You can no longer control the process happily .

It's because of if…else, Let's divide the code logic in a way close to life .

so to speak if…else Everywhere in the program , Even a tap of code , We automatically think of if…else The corresponding business line , How natural ！

3、 premature optimization , Not optimization

I met a colleague before , I always like to talk about expansibility with my mouth closed , Say which scene might be used , So stay in advance .

But in fact, it comes to the later development ,80% The probability of is no longer used to these optimization points . It's equivalent to spending energy on events that didn't happen .

Actually , It can also understand , Because product managers always easily The need to change , As a good programmer, we , I always want to predict these changes in advance , With Minimum The cost of completing the modification .

But actually at the beginning of the project , It belongs to an unstable development period , There are many variables .

If you optimize too early , For example, adding extra database fields , The optimization of unknown scenarios, such as very fine divided Services , In fact, it doesn't mean much .

premature optimization , Not optimization , The real project pain points will not be exposed at the beginning , When we are completed by the project Abused Once , Then you will naturally know how to optimize .

4、 Most projects are just adding, deleting, modifying and checking

Now the Internet project is actually putting life Digitization , The process of digitization must be dealing with data .

therefore , Most projects are actually solving where the data comes from , The question of where to go back .

As for the technical scheme adopted , It's just that the solutions are different . Finally, it has to fall to the ultimate goal of data processing .

And the data processing can not escape the addition, deletion, modification and query , This is also the meaning of many projects ！ Through continuous data processing , Present a virtual world closer to our life .

5、 The era of one person provoking a product is over

The Internet industry has developed to the present 20、30 Years. , From limited to professional use , Up to now, the application is popular . It can be said that users have changed from Xiaobai who didn't understand anything , Upgraded to a senior experiencer .

And the excellent products born during this period , Has been deeply bound to the user , We want to rely on ourselves to reverse users' usage habits , Almost impossible , Not to mention the possibility of being sniped by large enterprises .

therefore , Want to develop a phenomenal product alone , It's really difficult ！ It's like missing 80, 90 Like the spring tide in the S , It's hard for us to shake this mature market .

Of course , The prosperity and development of the Internet has also laid the foundation for us latecomers , A lot of standardized frameworks have been customized , image TCP、HTTP etc. ,
It also provides a lot of convenience for our development work .

6、 Programmers really have a high hairline ！

Last , Let's talk about the cruelest truth about programmers . you 're right ！ It's our bright forehead . That's the symbol of a senior programmer , It's the most beautiful scenery in the office ！

I believe as long as we work hard , One day , Will reach this level ！≥Ö‿Ö≤
