The only truly secure system is one that is powered off, cast in a block of concrete and sealed in a lead-lined room with armed guards - and even then I have my doubts.
唯一真正安全的系统是关闭的,浇筑在混凝土块中,并密封在有武装警卫的铅衬房间中——即便如此,我仍有疑虑。
The stock market is full of opportunities, but you have to be patient to find them.
Chaos isn't a pit. Chaos is a ladder. 
Happiness cannot be pursued; it must ensue.
