发帖数: 193 | 8 来自主题: JobHunting版 - 新鲜电面经 你说的都对，除了倒数第二行。mutex解锁在acquire semaphore后立马做了，但是既然
semaphore已被writer全部占用，另一个writer也进不来，所以代码没错。当然，如果
你不封装writer lock ,用C直接acquire /release writer lock，你把release押后也
是可以的。
"所以在lockWrite里面一直加semaphore,加不上去的时候应该是要挺得＂
Write的时候，要把semaphore收回，有些reader已经release了，所以立马收回，有些
正在reading，那就wait了，但不是busy waiting。这个你觉得有问题吗^_^ |

几个月前，想买房子，去了一家open house，碰见了这个agent，之后他就开始带我们看房子。其

negotiation 能力，但是感觉他还是很卖力的带我们看房子，也挺辛苦的，于是希望让他能挣些
钱。虽然有些心理准备，可是negotiate过程中，真的感觉他太不能干，而且太偏向seller，几乎
就是seller agent的传声筒。从没有见过什么counter offer。最可恨的是后来竟告诉我们
seller的要价竟然高于以前希望的。终于受不了了，决定换agent。
从本版以前的讨论看到，说不能随便换，又保护条款。像不能卖前一个agent带你看过的房子，协议
过期后六个月还有效，等等。我现在就是想请教各位：
1。是不是我的协议过期了？（实际上这里有个小插曲，11/21/2010 实际上是我们递offer 的日

发帖数: 22634 | 48 我现在开始同意你的看法。从这个角度看：
唱歌/工程数学（不是陶天才那种）/工程物理学/信息学，更趋向于 acquired skill。
因为那些 traits in-line with common tasks of human（人人都会唱歌，
人人都会数数），所以会被自然选择所选择和淘汰。因为大多数人都 carry 那些
trait。。。所以，基本的智力，以及后天开发的差别，是更重要因子。
而钢琴/纯理论抽象数学/纯理论抽象物理（都指研究生院之后的钻牛角尖程度），
更趋向于 genetic coded trait。。。因为这玩意儿无法被自然选择所选择和淘汰，
更多的是作为隐性基因啥的对抗自然选择的机制所保留下来。。。如果先天不 carry
那些基因，后天 acquire 那些 skill 基本很难。
（比如，钢琴的拇指运动，违背所有自然生存对拇指的需求 —— 相对四指 vs 平行四
指）。
这个可以解释为啥钢琴和纯理论数学/奥数啥的，很多 child prodigy 的存在，其他
学科就没那么多。。。 |
