When the "Timedoutwaitingforthedebuggertoattach" issue occurs, it is usually because the connection is not established correctly in the debugging process. 1. Check whether the launch.json configuration is correct, ensure that the request type is launch or attach and there is no spelling error; 2. Confirm whether the debugger is waiting for the debugger to connect, and add debugpy.wait_for_attach() and other mechanisms; 3. Check whether the port is occupied or firewall restricted, and replace the port or close the occupied process if necessary; 4. Confirm that the port mapping and access permissions are configured correctly in a remote or container environment; 5. Update VSCode, plug-in and debug library versions to solve potential

To use C for high frequency trading (HFT), focus on performance, stability, and low latency. 1. Master the underlying system knowledge, including CPU caching mechanism, system call overhead and using perf tools to analyze hot spots; 2. Optimize compiler options and code structure, such as enabling -O3, LTO, reducing the use of virtual functions, and optimizing the structure layout; 3. Use zero-copy technology, non-blocking UDP, batch data processing to achieve low-latency network communication, and use shared memory or RDMA if necessary; 4. Emphasize debugging and testing strategies, including static analysis, unit testing, stress testing and light-weight logging, and verify the correctness of logic in combination with the simulator.

To call Python code in C, you must first initialize the interpreter, and then you can achieve interaction by executing strings, files, or calling specific functions. 1. Initialize the interpreter with Py_Initialize() and close it with Py_Finalize(); 2. Execute string code or PyRun_SimpleFile with PyRun_SimpleFile; 3. Import modules through PyImport_ImportModule, get the function through PyObject_GetAttrString, construct parameters of Py_BuildValue, call the function and process return

Smart contracts are one of the core innovations in blockchain technology, which enables trustless automation protocols through code. It is not a downloadable APP, but an underlying technology. For ordinary users, you are exposed to various DApps built on platforms such as Ethereum and Solana. For developers, which platform to choose depends on the specific needs of the project, such as performance, cost, security, and target user base. As technology continues to mature, smart contracts will show great potential in more fields such as finance, gaming, and the Internet of Things.

A common method to traverse two lists simultaneously in Python is to use the zip() function, which will pair multiple lists in order and be the shortest; if the list length is inconsistent, you can use itertools.zip_longest() to be the longest and fill in the missing values; combined with enumerate(), you can get the index at the same time. 1.zip() is concise and practical, suitable for paired data iteration; 2.zip_longest() can fill in the default value when dealing with inconsistent lengths; 3.enumerate(zip()) can obtain indexes during traversal, meeting the needs of a variety of complex scenarios.
