dc := diagram.NewGroup("GCP")
dc.NewGroup("services").
    Label("Service Layer").
    Add(
        gcp.Compute.ComputeEngine(diagram.NodeLabel("Server 1")),
        gcp.Compute.ComputeEngine(diagram.NodeLabel("Server 2")),
        gcp.Compute.ComputeEngine(diagram.NodeLabel("Server 3")),
    ).
    ConnectAllFrom(lb.ID(), diagram.Forward()).
    ConnectAllTo(cache.ID(), diagram.Forward())

dc.NewGroup("data").Label("Data Layer").Add(cache, db).Connect(cache, db)

public interface HttpApi {

    @GET("person")
    Result<Person> getPerson(@Query("id") Long id);
}

/** * injection uses **/
@Service
public class TestService {
    @Autowired
    private HttpApi httpApi;

    public void test(a) {
        // Initiate an HTTP request using httpApi}}Copy the code

Jmeter: Apache open source stress testing tool. Providing a GUI interface allows for point-and-click operations and scripting to improve test automation. It is not limited to Web testing and supports more stress testing scenarios. 97% of the people I work with in testing have used it. Would you like to take a look at the source code? Pure Java implementation

11, Mybatis – Plus: a user-friendly Java operation database framework. MyBatis enhancement kit, provides some efficient, practical, fast functions, using it can effectively save your development time. For example, to switch data sources, you only need to modify the configuration file

List<User> userList = userMapper.selectList(
        new QueryWrapper<User>()
                .lambda()
                .ge(User::getAge, 18));Copy the code

12, BilibiliTask: Bilibili automatic completion of task projects. This project is completed automatically by GitHub Action: daily tasks, coins, live check-in, etc., and the results can also be pushed to wechat. It is an interesting project to solve repetitive labor. According to the project home page tutorial, it takes a little time to configure, once and for all

JavaScript project

Python project

Asciinema: Terminal logging tool. Forget recordscreen software, plain text recording terminal operation tool. It is easy to install and use, and the generated record file is very small, but it needs to play with JS files

19. Offender Python: Microsoft’s open-source browser automation tool, which can operate the browser in Python. Supports Chromium, Firefox, and WebKit browsers on Linux, macOS, Windows, and Windows

20. Wagtail: One of the most powerful open source Django CMS (content management system) available today. I rarely use the word “most,” so let’s save time by talking about what amazes me about it. First of all, the project is updated and iterated actively. Secondly, the functions mentioned on the first page of the project are free, and there is no such operation as inexplicable lock. Wagtail focuses on content management without tying up front-end implementations. StreamField is an interesting technology that makes your content flexible and structured. It even supports A/B testing, and eventually Google, NASA, and others are using it

Redis-memory-analyzer: Redis real-time memory analysis tool. I am curious about how it is real-time access to redis key situation and information, look at the source scanner. Py file. The scan_iter method is used to control the amount returned by the scan key. Yield is then used to reduce memory usage, and finally the register_script method calls Lua scripts or pipeline methods to improve the efficiency of obtaining key information. After analysis, it is found that this tool can be used in the case of large amount of data, and the real-time requirement is in the second or minute level

Practical Python: A free introductory tutorial on Python from David Beazley He is the author of the Python Cookbook, Third Edition, and the Python Reference Manual, which includes hands-on teaching and after-school practice problems. Online learning, the tutorial directory is as follows:
