Ten years' experience of Software Engineer

Active address ： Graduation season · The technique of attack er

History and status quo  

I am 2008 Graduated in computer science and technology , College is a learning scum , College is only a scratch in programming ,

After graduation, I went on a short-term study 、 Study .2009 At the end of the year, I joined an education and training company for the first time to develop training websites and related software services , Mainly in the database CRUD operation , The development language is C#, Later, I joined a company that did the workflow of government and enterprise , The development language is C# and Java.

Now I am working in a manufacturing company to develop software for upper computer and motion control , The main use of C# programing language , A few projects use C++.

Industry role conversion

I have been working on the Internet before , Most of the projects developed are workflow OA、 Purchase, sale and deposit 、ERP Such as system , Almost all have nothing to do with the equipment , Generally speaking , appear Bug Are related to their own logic and programs . Back to pit manufacturing , Almost all software programs are related to devices 、 Motion control of machine tool 、PLC of , Before the discovery, the framework in the Internet field was almost useless in the manufacturing field .

Software and programs for manufacturing , Not only logic and procedures are needed , You also need to know about the equipment related fields , such as PLC The memory area of 、 Memory address 、 equipment TCP Communication, etc . Personal understanding ： Another industry , Even the same software and program development , It's basically a new beginning .

A sense of accomplishment

When I was working on motion control software , programing language C#, But you need to call C++ Unmanaged class library for DllImport, There was a need to use C++ Class , Example of using the original supplier Demo, It runs normally on many industrial computers , But there are 10% After running the motion program on the industrial computer for a period of time 【 For example, running point motion 1000 Time 】 The program crashed 【 The memory cannot be write】, Later, we found that C++ Class object of 【 unmanaged 】 go to C# class 【 trusteeship 】 You need to use key classes System.Runtime.InteropServices.Marshal Open up memory and free memory , The code will not crash after correction .

As a type of technical work , Industry logic , Industry demand , Communication with customers , The program appears Bug Or problems , Be able to find out the crux in time . The latest technology iterations and the latest frameworks used .

A person's technical accumulation , Experience 【 Especially the solutions to problems 、 Ideas 】 Is a person's precious wealth

When developing new software projects , There may be a variety of ideas and solutions , Don't worry, just go ahead , You can spend a few days thinking about the pros and cons of several solutions , Finally, choose a comprehensive optimal solution .（ Of course , Except for projects that are really launched in an emergency ）. Choose the same solution , When the framework , The colleagues in the project should divide their work and cooperate , Uniform procedures 、 Code style. , Easy for other colleagues to understand , Easy to expand and maintain in the later stage .

Programming language debate

Programming language debate , No garbage and the most powerful programming language , The existence of programming languages makes sense . Programming languages focus on practicality , Every programming language has its own good usage scenarios . Of course , It is also related to the programming languages that the team is good at .

such as , Few companies use C++ Development Web Website project ,Java Almost all of them are used in Internet related , Almost all embedded programming is C or C++.

Occupation planning

Enter the workplace , Writing your own program is as important as finding more practical AIDS .

Don't rewrite the program completely , Don't use all the fixed frames Spring,Hibernate

To college students ： If you are determined to engage in programming ,IT, Internet and related industries , You don't need to be an expert in programming in college , At least proficiency level , Before graduation, you should have a solid foundation in a certain programming language , Familiarity with any programming language is sufficient .

I have been working hard since I started my career , Focus on learning and accumulating experience ,

The so-called ability improvement , Mainly technical management 、 Technical internal skill 、 Technical horizon 、 Technical communication and technical copywriting .

Technology is a comprehensive capability , It's not just code logic , We also need to pay attention to industry trends 、 Industry demand, etc
