Click the “blue text” above to follow us Yesterday, my friend Xiao Li called me: “Brother Feng, help! Our API service always lags during peak times, and I suspect it’s a middleware issue.” I laughed; isn’t this an old story? No matter how fancy the code is, it can’t escape the performance hurdle. Especially in … Read more
Compiled by: Ling Min, Hezi Cola Since its debut on May 2, the Mojo programming language from Modular has generated significant interest among developers, with over 120,000 developers registering to use the Mojo Playground and 190,000 actively participating in discussions on Discord and GitHub. Jeremy Howard, co-founder of Fast.ai and data scientist, stated, “Mojo may … Read more
1. Why is Concurrency Programming the Key to Breaking Python’s Performance Bottleneck? In the 2025 Python Developer Survey, 82% of performance optimization cases involved concurrency programming. Faced with I/O-intensive tasks (such as network requests and file operations) and CPU-intensive tasks (such as image processing and data analysis), the combination of asynchronous/multiprocessing/multithreading can bring astonishing performance … Read more
1. Prioritizing Development Efficiency The simplicity of Python: Python’s syntax is close to natural language, and the amount of code is usually only 1/5 to 1/10 of that in C. For example, to implement matrix multiplication: # Python result = numpy.dot(matrix_a, matrix_b) In contrast, C requires manual memory management, loops, and pointers, significantly increasing code … Read more
With the rapid development of technologies such as 5G communication, millimeter-wave radar, and high-speed computing, microwave circuits impose higher requirements on PCB design. Traditional surface mount technology (SMT) shows significant limitations in high-frequency applications, particularly with the increasingly prominent performance degradation issues caused by parasitic effects. This article will delve into the embedded design technology … Read more

1. Development of the ARM Architecture The ARM architecture (Advanced RISC Machine) is a microprocessor architecture based on the principles of Reduced Instruction Set Computing (RISC), originally designed and launched by the British Acorn Computer Company in the late 1980s. The evolution of the ARM architecture is as follows: 1.1. Early Development (1980s-1990s) 1985: Acorn … Read more
