Paying attention, in two different mediums.在两种不同的介质里，练习认真观察。
I’m Zhicheng, an embedded software engineer based in Singapore. I write firmware for constrained systems, run long distances, and keep notes about the decisions behind both.我是智诚，一名生活在新加坡的嵌入式工程师。我为受限系统写固件，跑长距离，也记录两件事背后的决策与观察。
This site collects implementation notes, bring-up logs, debugging patterns and the occasional thought that was too useful to leave in a scratch buffer.这里记录一些实现笔记、启动过程、调试模式，也记录工作、跑步和生活里那些不愿让它们消失在临时缓冲区中的片段。
A man should know himself. Even if it does not bring him truth, it at least serves as a rule for his life; and there is no better rule than that.人应当认识自己。这也许不能使人获得真理，但至少可以作为生活的准则；而生活没有比这更好的准则了。
