关于“工程”vs“科学”的中肯评论
这是Operating Systems, Design and Implementation第3版的一段话，说的是死锁这个问题：
The simplest approach is the ostrich algorithm: stick your head in the sand and pretend there is no problem at all. Different people react to this strategy in very different ways. Mathematicians find it completely unacceptable and say that deadlocks must be prevented at all costs. Engineers ask how often the problem is expected, how often the system crashes for other reasons, and how serious a deadlock is. If deadlocks occur on the average once every five years, but system crashes due to hardware failures, compiler errors, and operating system bugs occur once a week, most engineers would not be willing to pay a large penalty in performance or convenience to eliminate deadlocks.
另外还有“New Jersey school” vs "MIT school"的说法。
