Applications of C Language in Big Data: Data Processing and Storage The C language, as an efficient and flexible programming language, is widely used in various system development and algorithm implementation. In the field of big data, due to its outstanding performance and control over hardware, C language is utilized for data processing and storage. … Read more
Introduction Often, the datasets we need are very large due to high resolution, necessitating storage in chunks (in fact, many high-resolution datasets are provided for download in a chunk-compressed format).The naming convention of these chunk files usually indicates their corresponding latitude and longitude ranges, but finding and verifying them one by one can be cumbersome, … Read more
The first time I truly experienced the power of sets was while working on a user behavior analysis project for a social networking site. As I stared at the progress bar on the screen, my heart raced—I had to deduplicate 15 million user browsing records in real-time and detect abnormal behaviors. Using a list? The … Read more
1. Introduction: The Core Power of Dynamic Sequences The list, as the most flexible mutable sequence type in Python, is a core tool for handling dynamic data collections. Unlike tuples, lists support real-time modifications, dynamic expansions, and a rich set of built-in methods, making them the preferred structure for scenarios such as data collection, algorithm … Read more
According to reports from Electronic Enthusiasts (by Huang Jingjing), AMD has announced the launch of the fifth generation AMD EPYC Embedded processor, expanding its x86 embedded processor product line.The AMD EPYC Embedded 9005 series CPUs are optimized for the embedded market, achieving a balance between computing power and specially designed embedded features, enhancing product lifespan, … Read more
Over the years, I have seen too many on-site programs, especially in the area of PLC sequential control, where the choice of variable types is poor, leading to numerous pitfalls. A few days ago, I went to a food factory to troubleshoot, and the program almost drove me crazy. They used a bunch of BOOL … Read more
Last week, I helped a colleague solve a problem with his temperature control system on the production line, which was frequently malfunctioning. After some investigation, it turned out that the variable type was not selected correctly, causing the decimal part to be truncated. This incident reminded me that we must discuss the topic of variable … Read more
Attention all workers! Today, I want to take you to witness a dramatic scene in the tech world—a once-glorious cloud computing is being overshadowed by its own offspring, Edge AI. This is not a family drama, but a revolution in data processing efficiency! Imagine this: cloud computing is like an old department store in the … Read more
Source | 51CTO What is edge computing? How does it differ from traditional cloud computing services? When might edge computing be the right choice for businesses? Edge computing is a form of cloud computing, but unlike traditional cloud computing architectures that centralize computing and storage in a single data center, edge computing pushes computing or … Read more
Introduction to MQTT MQTT (Message Queuing Telemetry Transport) is a lightweight messaging protocol based on the publish/subscribe model, designed for low-bandwidth, high-latency, or unreliable network environments. It is widely used in the Internet of Things (IoT), mobile applications, and distributed systems to enable efficient communication between devices. By reducing data transmission volume and simplifying communication … Read more
