After following, you can keep track of his dynamic information in a timely manner
text-overflow is used to control the display method when text overflows the container. 1. You can set clip, ellipsis or custom string values; 2. You need to set white-space:nowrap, overflow:hidden and fixed width at the same time to take effect; 3. Multi-line truncation requires -webkit-line-clamp and -webkit-box-orient; 4. It is often used to keep the layout neatly in tables, menus and card components; 5. Complete text should be provided through the title attribute and ensure that key information is not truncated. The final effect depends on the correct combination of CSS attributes to achieve single-line or multi-line text truncation.

Recommended method for sending POST requests in Java is the HttpClient introduced by Java11, which supports HTTP/2 and asynchronous operations, and the code is simpler; 2. For Java8 and earlier versions, HttpURLConnection should be used, and the request method, header information and output streams should be set manually; 3. When sending JSON data, you must set Content-Type to application/json and write through BodyPublishers.ofString() or getOutputStream(); 4. When sending form data, you must set Content-Type to application/x-www.

C name modification generates unique symbols by encoding function names, namespaces, classes, parameter types, etc. 1. The function name is prefixed with _Z; 2. The namespace and class names are nested in the form of length names, starting with N and ending with E; 3. The parameter types are encoded in order as i(int), d(double), R(reference), K(const), etc.; 4. The return type does not participate in the modification; 5. Use extern "C" to avoid modifications to be compatible with C. Different compiler rules are different. GCC/Clang follows ItaniumC ABI, and can view and reverse the symbolic names through nm and c filters. The final generated mangled name ensures function overloading and scope.

Pure CSS animated tables can be implemented by using CSS' transition, @keyframes and :hover. 1. Create a semantic HTML table structure; 2. Use CSS to add styles and hover animations, and achieve smooth transitions of background color and scaling through transitions; 3. Use @keyframes to define entry animations, so that table rows slide in one by one when loading; 4. Add class-based color transition animations to state cells, and dynamically discolor when hovering; 5. Implement responsive design through media queries, and turns to horizontal scrolling under the small screen. The entire process does not require JavaScript, and is efficient and compatible with modern browsers.

There are three common ways to convert char to int in C: 1. Use cast (int)c to obtain the ASCII value of the character; 2. It is recommended to use static_cast(c) to achieve a safer conversion; 3. If you need to convert a numeric character (such as '5') to an integer 5, you need to implement it through c-'0', and you should first determine whether the character is a legal numeric character in the range of '0' to '9'.

When the business logic is complex, the service class should be used to extract the logic beyond HTTP processing in the controller (such as user registration, pricing calculation); 2. When multiple controllers, tasks or commands need to reuse the same logic (such as data synchronization, report generation), the service class can avoid code duplication; 3. When better testability is required, the service class can conduct unit testing independently without relying on HTTP requests; 4. When multiple operations or services need to be coordinated (such as inventory, payment, notification, etc. in order processing), the service class can effectively organize the process. Service classes are usually placed in app/Services or subdirectories grouped by functions, and should be used through dependency injection to avoid excessive bloat and ensure single responsibilities. Therefore, as long as the controller is performing actual business work instead

To create a custom io.Reader, you need to implement Read(p[]byte)(nint, errorrror) method; 1. Define a type (such as struct) and implement the Read method, fill p from the data source and return the number of bytes and errors; 2. Write p in Read. If the data is insufficient, return part of the bytes and nil errors, and return io.EOF after reading; 3. You can use this reader in functions such as io.ReadAll; for example, CounterReader generates incremental bytes, StringReader reads strings, RandomReader generates random bytes, and any type that implements the Read method satisfies the io.Reader connection. For example, CounterReader generates incremental bytes, StringReader reads strings, and RandomReader generates random bytes.

Transparent properties in Vue.js refer to properties that are passed from the parent component to the child component but are not explicitly declared as props. They are automatically applied to the root element of the child component. 1. By default, Vue3 will pass undeclared attributes such as class, style, id, event listener, etc. to the root element of the subcomponent; 2. If the subcomponent template has multiple root nodes, inheritAttrs:false must be set and use v-bind="$attrs" to manually control the attribute binding position; 3. $attrs contains all attributes that are not declared by props or emits, which can be used to flexibly distribute the transparent attributes; 4. This mechanism makes the encapsulated component closer to native HTML behavior,

The answer is to write a TCP scanner using Go's net package: first define the target host and port range, try to connect to each port through net.DialTimeout, and the port will be open if the connection is successful; 2. To improve performance, use goroutine concurrent scans, and collect results through sync.WaitGroup and channel; 3. Timeout needs to be set to avoid blocking, limit concurrency amount to prevent resource exhaustion, and properly handle network errors; 4. Optional functions include using flag package to add command line parameter support to achieve flexible configuration of host and port range; 5. When using it, you should comply with the authorization principle and scan only allowed targets. Complete implementation includes sequential scanning, concurrent optimization and parameter configuration, and finally achieve an efficient and

To find out the slow running parts of Python code, using cProfile is a built-in and efficient way to do it. 1. Run from the command line: Use python-mcProfilemy_script.py to obtain information such as the number of function calls, total time consumption, single time consumption, and accumulated time consumption. 2. Sort output: Sort by key columns through the -s parameter, such as -scumtime sorted by cumulative time to locate bottlenecks, -stottime viewing the function itself time, and -sncalls discovers high-frequency calling functions. 3. Save the results: Use -profile_output.prof to save the data as a binary file, which is convenient for subsequent analysis using the pstats module, such as sorting and typing after loading.

Singleton pattern ensures that a class has only one instance and provides global access points. C 11 recommends using local static variables to implement thread-safe lazy loading singletons. 1. Use thread-safe initialization and delayed construction of static variables in the function; 2. Delete copy construction and assignment operations to prevent copying; 3. Privatization of constructs and destructors ensures that external cannot be created or destroyed directly; 4. Static variables are automatically destructed when the program exits, without manually managing resources. This writing method is concise and reliable, suitable for loggers, configuration management, database connection pooling and other scenarios. It is the preferred singleton implementation method under C 11 and above standards.

Use Collectors.toMap() to convert List to Map. First, define the key through Person::getId, Function.identity() or Person::getName. If there is a duplicate key, use three parameters toMap() and specify the merge strategy to ensure that the key is not null to avoid exceptions. Finally, the conversion is completed through streaming operations and the Map is returned.

Manually added event listeners and timers must be cleaned before component destruction, otherwise memory leaks and unexpected behavior will occur. 1. Global events added with addEventListener (such as window, document) must be cleaned in beforeDestroy (Vue2) or onBeforeUnmount (Vue3), and named functions must be used to ensure consistent references; 2. All setInterval and setTimeout should save the ID and be cleared when destroyed to avoid repeated execution causing performance problems or status errors; 3. Multiple listeners or third-party subscriptions (such as WebSocket)
