How to Get the Goroutine ID?
In an operating system, each process has a unique process ID, and each thread has its own unique thread ID. Similarly, in the Go language, each Goroutine has its own unique Go routine ID, which is often encountered in scenarios like `panic`. Although Goroutines have inherent IDs, the Go language deliberately does not provide an interface to obtain this ID. This time, we will attempt to obtain the Goroutine ID through the Go assembly language.

Go Generics: A Deep Dive
Overall, the benefits of generics can be summarized in three aspects: 1. Types are determined during the compilation period, ensuring type safety. What is put in is what is taken out. 2. Readability is improved. The actual data type is explicitly known from the coding stage. 3. Generics merge the processing code for the same type, improving the code reuse rate and increasing the general flexibility of the program. However, generics are not a necessity for general data types. It is still necessary to carefully consider whether to use generics according to the actual usage situation.

A Deep Dive into Gin: Golang's Leading Framework
Gin is a HTTP web framework written in Go (Golang). It features a Martini-like API, but with performance up to 40 times faster than Martini. If you need smashing performance, get yourself some Gin.
High-Performance Python: Asyncio
Unlike multithreading, `asyncio` is single-threaded, but the mechanism of its internal event loop allows it to run multiple different tasks concurrently and has greater autonomous control than multithreading.Tasks in `asyncio` will not be interrupted during operation, so the situation of race condition will not occur.Especially in scenarios with heavy I/O operations, `asyncio` has higher operating efficiency than multithreading. Because the cost of task switching in `asyncio` is much smaller than that of thread switching, and the number of tasks that `asyncio` can start is much larger than the number of threads in multithreading. However, it should be noted that in many cases, using `asyncio` requires the support of specific third-party libraries, such as `aiohttp` in the previous example. And if the I/O operations are fast and not heavy, using multithreading can also effectively solve the problem.
Mastering Python Async IO with FastAPI
Asynchronous I/O is implemented at the bottom layer using "coroutines" and "event loops". "Coroutines" ensure that when the thread encounters marked I/O operations during execution, it doesn't have to wait for the I/O to complete but can pause and let the thread execute other tasks without blocking. "Event loops" use the I/O multiplexing technology, constantly cycling to monitor I/O events. When a certain I/O event is completed, the corresponding callback is triggered, allowing the coroutine to continue execution.

Is Flask Dead? Is FastAPI the Future?
The article mainly discusses the current situation and development of Flask and FastAPI in the Python framework field. By comparing the adoption of new projects, the number of GitHub stars, and the proportion in official surveys, it shows that FastAPI's popularity has risen and exceeded that of Flask. Looking back at the development of web frameworks, although Flask once had advantages, it is limited by issues like plugin maintenance. FastAPI stands out with its asynchronous design, Pydantic data validation, and ASGI support. It also explains the decline of Flask's popularity from aspects such as community activity and discussion frequency. Finally, it introduces the advantages of the Leapcell platform suitable for deploying both.
