Firefox远程连接的时候体验非常糟糕

换成Chromium罢。感觉全面弃用Firefox可能是早晚的事了。

NVMe SSD not detected

I am facing the problem due to

This may due to the tampering with the hardware made by the seller. Unfortunately, the only solution is to return the goods.

两校写作班子的两位负责人迟群和谢静宜

结局大不相同。迟群很张扬，下场不好；谢静宜相对低调，而且喜欢拿小本本记录领导讲话，后来免予起诉，还能享受退休待遇。
