By chance , I need to use network disk service , Is to upload the file to a certain place （ Don't say which service it is , It's all the same ）. This is only a very simple operation , First, copy the files in a folder on the hard disk to the remote server , Then perform some database operations , Give the file a name , Then provide it to download , That's it .

It is a large company that provides online disk Services , Large scale , It is estimated that many hackers visit every day , So they need some safety measures , When uploading and downloading, you have to verify whether the file has been tampered with , It's all right .

however , The most basic function is just to list files 、 Read the file 、 Upload files , Then close the connection , Write success in the log , Or if there is an error, write the reason for the error in the log . This is not rocket technology , Actually, I use it myself wininet API Write this code , The service is used PHP and MySQL, Although it can't reach the enterprise level , But it can also support the uploading of hundreds of thousands of files 、 Downloading and logging —— A person writing code is about twoorthree weeks of work ？

However , The client of the special upload tool I used is 230MB, contain 2700 Multiple files .

Yes , You read that right ,2700 Multiple files ,237MB Executable files and all kinds of garbage , Just to copy files to the server . This can no longer be called inflation , It's not over designed , This is completely unreasonable .

actually , Not only this upload tool , Nowadays, any software of any large software company is the same .

In the computer 99.9% The above code is useless garbage

I know what's going on , I've also seen other programmers' implementations . The root cause is , Programmers simply don't know how to achieve their goals through efficient underlying code , They have never even seen the low-level efficient code . How can you make something you haven't seen , We need to do better ？

Write a safe 、 Software to quickly upload files to the server , It takes up to one twentieth of the amount of code . Just one file , One exe Documents are enough , It doesn't need hundreds at all DLL. It is entirely possible , And it will be easier 、 More reliable 、 More efficient , It's also easy to debug , It can even work more stably .

Code bloat seems to be a bit of an old guy like me , After all, I'm old . But what these old guys are thinking about is not that the code is slowing down 50%、 The scale has increased 50%. The actual situation is far more than that .

I believe in your computer 99.9% The above code is useless garbage , Will never be run . But all this code is piled up there , Pile on 65 individual DLL In the document , This is because programmers want to do something less important , For example, save a picture , But they don't know what to do , Just import a lot of garbage to realize .

As I said , I shouldn't be angry watching young programmers do this , After all, this is the way they learned to realize . They have no idea what high-performance development looks like , I have never seen what software with limited conditions looks like . If you tell them , The original Elite The game can generate the whole galaxy , Yes 3D Dogfight , There is a career system , trading system , And explore thousands of planets , And all this only 64KB, They can also accept , But there is no way to understand the gap between this and current software .

CPU And memory are limited is the golden age of programming

Why do I care about this matter ？ There are many reasons , The simplest thing is when you spend twothousand times the time to do something , It should work . But more importantly , That's true. 99.9% Of CPU Time is wasted on this garbage . Execute hundreds of thousands of instructions per second , The result is useless . Originally, my computer should be in a very low power consumption , The fan should not turn , Because what I'm doing now is just wordpress Just writing in it .

Today's computers are fast , It's really magic . Everything you can think of , Can refresh once on the screen 1/60 seconds . however ！ When I was there Surface The notebook （ Almost new ！） Click the hard disk icon on , I can see the obvious delay , The computer draws the user interface little by little . It will take a long time , I guess it will take at least half a second , about CPU It's like billions of years .

If I'm right , Because there is 99% Garbage ,99% All the electricity is wasted , This can no longer be described as a crime . What has all this wasted power done ？ I don't know , But look at the task manager ： A lot of things that don't know what they are or what they are doing .

I'm just writing an article now ,Windows It's about to run 102 Background processes .NVidia The video card has 6 A process , Some even have child processes . What are you doing ？ I didn't play games , For graphics cards, what I'm doing now is similar to 20 It made no difference years ago , But just 6 A process .

Microsoft Edge Browsers also have 6 A process , its Web View also 6 individual . I didn't even open it Edge. Maybe I opened one yesterday SVG chart , And here it is 12 A useless process wastes memory and CPU？ This is simply unreasonable .

That's why everything doesn't work properly , Why is everything slow , Why do you buy new mobile phones and new TVs every year , Buying new ones is just to run more junk programs .

I think pessimistically , Things will only get worse , Because like Facebook、Twitter、Reddit These stupid Big Mac companies are the current trend . There are thousands of people in every company “ The programmer ”, Use machine learning to learn from GitHub Copy and paste these useless junk code . Add two numbers to use 32 individual DLL and 16 individual Windows There are hundreds of millions of lines of code in the service .

Twitter There are 2000 programmers . but Tweetdeck Occasionally, the timeline of a user cannot be loaded . This bug It has been more than four years , I guess no one knows why , The code behind it is just a pile of copy and paste garbage .

Besides, Reddit, The function of reading titles from links cannot be handled correctly & And semicolon , This is all 2022 Years. . I guess they do, too 2000 Multiple programmers , But no one even writes text analyzers , So what do they do with money ？

once CPU And memory were limited , Is the golden age of programming ; And now , We live in a pile of inefficient garbage . Alack! ！
