Today, while studying the asynchronous FIFO read and write clock synchronization in FPGA, I noticed an issue: when connecting two different clocks, it is challenging to achieve complete synchronization. As a result, at a certain moment, the edge of the high-precision clock may appear in the middle of the edge of the low-precision clock, leading … Read more

Recently, I recommended a Linux book titled Learning Linux the Right Way, and I even held a giveaway for a few readers. In the preface of this book, the author discusses why one should learn the Linux system, and I think it is well-written. The author introduces the topic with a question from a student … Read more
Have you ever felt that breastfeeding is somewhat like connecting via Bluetooth? Sometimes the signal is strong, and the connection is established immediately; other times, the signal is weak, and the baby cries out, leaving the mother anxious as the connection fails. Once one transfer is complete, another must be initiated, and once all are … Read more
Hello everyone, today I am sharing an article published in JACS: Metallo-coiled Coil Stabilization via Chemical Cross-Linking: Implications for Gd(III)-Based MRI Contrast Agents. The corresponding author is Professor Anna F. A. Peacock from the University of Birmingham, whose research group focuses on the design and application of functional metal peptides. Coiled coils are a class … Read more
Semiconductor equipment development is a highly complex system engineering task that requires comprehensive consideration of various factors such as technical performance, process adaptability, environmental control, and economic viability. Among these, precision, stability, ease of maintenance, and reliability are the four core elements, whose prioritization and balance need to be dynamically adjusted based on specific process … Read more
Recently, a new architect joined our company, and on his first day, he asked the operations team for a “bare metal” server. I went over to take a look, and the command line with black background and white text was flashing rapidly on the screen, leaving me dumbfounded—it’s 2025, and there are still people working … Read more
Registration: European Humanoid Robot Summit 2025 Abstract:IEEE has released a standard framework for humanoid robots, focusing on classification, stability, and HRI (Human-Robot Interaction), coordinating SDOs (Standards Development Organizations) to establish standards, with large-scale deployment expected as early as 2027, facilitating the safe integration of humanoid robots into industrial, service, and public scenarios. 1. Analysis of … Read more
[Image][Image]Written by Ding Lingbo. For robots to achieve general usability, they must operate stably in real-world scenarios to cope with various dynamic disturbances, including terrain changes, external forces, and alterations in their own physical properties. To achieve this goal, domestic researchers have recently proposed an innovative two-stage reinforcement learning (RL) framework: Any2Track, which can track … Read more
The development of recording products has a history of over a decade since 2000. Currently, there are generally two common architectures for recording hosts on the market: PC architecture and embedded architecture. How to choose the right recording system? Let’s first understand the differences between the two. Appearance Comparison Embedded Architecture The embedded architecture recording … Read more
