In C++ development, debugging is an indispensable part of the process. Whether it is finding logical errors in the program or detecting memory leaks, the right debugging tools can significantly enhance our work efficiency. This article will introduce two commonly used C++ debugging tools: GDB and Valgrind, and provide detailed usage methods and code examples. … Read more
When programming in C++ under the Linux environment, multithreading provides excellent concurrency capabilities, allowing programs to perform more efficiently when handling complex tasks. However, multithreaded programming is not without its challenges; deadlock issues lurk like hidden “killers,” potentially causing programs to become stuck. Once a deadlock occurs, the program is trapped in an unbreakable loop, … Read more
Batch Deletion of Empty SHP and GDB Feature Classes/ Tables – Tool User Guide Tool Functionality This tool is used to batch scan a specified folder and automatically delete: 1. All SHP files with a record count of 0 in the folder and its subfolders; 2. All feature classes and tables in GDB databases with … Read more
On the long road of software development, bugs are like “little monsters” hiding in the dark, occasionally jumping out to cause trouble for developers. Once, the European Space Agency (ESA) launched the Ariane 5 rocket for the first time, which was an important moment in the history of space exploration, but a single line of … Read more
As the title suggests, let’s get started. First, prepare the program as follows: #include <iostream> #include <csignal> #include <atomic> std::atomic<int> running(1); void signalHandler(int signal) { std::cout << "Received signal " << signal << std::endl; running = 0; } int main() { signal(SIGTERM, signalHandler); while(running.load()) { } std::cout << "End" << std::endl; return 0; } After … Read more
In the production and collection activities of natural resource geographic information data, ArcGIS and ArcGIS Pro are possibly the most widely used GIS software. Correspondingly, Geodatabase databases (File GDB, Personal GDB) are also the most widely used formats for data production and aggregation. In the geographic information data collection and mapping production activities based on … Read more
When it comes to learning embedded systems, there is undoubtedly a lot to learn and remember. Writing this down helps me reconstruct problems and receive guidance from peers. 1. What is GDB? During our programming journey, we inevitably encounter program crashes, variable anomalies, and logical errors. This can be particularly frustrating for technical support workers … Read more

1. Background and Significance In our daily work, we sometimes need to batch convert database tables into points. ArcGIS does not provide a direct tool for this, so we need to link several tools together in the model builder to create a new tool. Please continue reading. 2. General Approach Use the “Iterate Tables” iterator … Read more
