Click the “blue words” to follow us I was just lying on the office couch, chewing on a nearly cold pancake, when suddenly I received a WeChat message: “Bro, help! The online service is down again, this is the third time! Are our failure drills really useful?” Seeing this message, I couldn’t help but smile. … Read more
Click the blue text to follow Hello everyone! Today we are going to discuss an interesting topic – fault injection. When developing robust systems, we need to ensure that not only the normal processes run smoothly, but also validate how the system performs under exceptional conditions. Fault injection is a testing method that simulates system … Read more
Product reliability is designed. It is produced and managed. －Qian Xuesen 1. Circuits Are Designed. Don’t Just Draw, Be a Designer. An electrolytic capacitor soldered next to a heat sink causes the related circuit parameters to drift, resulting in unstable machine parameters; the inconsistency in the color of green LEDs makes them look unattractive. Each … Read more
