1. Too many candidates from one particular country. When diversity is not

country should get more than 10% of H1B or GC.

发帖数: 9094 | 40 A widely-accepted idea is that work and play cannot possibly be used in the
same sentence. Indeed, whoever thought they were must have heard wrong.
Work is something you do so that you have enough money for a decent method
of recreation. However, that is not always the case, as studies have shown
that interest in one’s subject quickens the rate of learning, which is true
if you think about it. If you find something intriguing, you would, at
any rate, be keener to learn about it. If you believe i... 阅读全帖 |

发帖数: 9094 | 41 A misnomer is that when a parent teaches a kid new stuffs, the kid does not
learn the problem-solving skills. This might NOT be the case. Problem solving
skills could be learned through analyzing conditions given, theories learned
, and prior experiences accumulated when solving similar problems.
Once a kid grasps the essence of problem-solving skills, he or she will
become confident in dealing with unknown problems.

5 things your brain does better than a computer

Brains are better
For as long as computers have been around, they've been doing things better
than humans. The earliest computing devices were designed to calculate
numbers faster than people, and today's computers can do everything from
calculating pi out to a few billion places to rendering the latest Hollywood

我不是为了反对而反对，又不是吃饱了撑的！
我反对的原因没说过吗？上次转的文章基本代表了。观点有互相冲突吗？还是反对的原
因和角度各不相同呢？那我列个一二三吧。
一，CC 的推手们向各州推动 CC的过程不公开不透明，各州是被 stimulus money 和
No Child Left Behind 的 waiver 所贿赂上船的。CC自我推销的语言多是空话，甚至
谎言。
CC说是 state led. 事实：它从来不是。
二，CC 从来没有在任何一个学校试验过。他们自己称有大量研究支持这个标准，但却
拿不出一个研究的 citation。我在 CC的官网没找到，如果那位找到了，请分享！
既然没有任何试点，没人知道 CC 是否真的能改进中小学教育。反正 Bill Gates 的孩

发帖数: 22634 | 44 写完发现，这么写还是有漏洞，漏洞在于，这个会导致在 solve 跟 v
有且仅有两个 edge，并且没有其他 edge 的 vertex 的过程中，会
出现颜色 2 的 edge，该颜色 2 的 edge 可能连接正常 vertex。
不过修掉这个漏洞也不难，概念其实不变，只是写法更加繁琐坑爹。
实际上应该做的是，先解决所有只含有两个 degree 为 2 的 edge
的 vertex，用上面 （2.2） 的办法。。。不过不是在一个平面 solve，
而是在 hyper-graph 里面 constructive 的算法去 solve，
相当于 solve 在 hyper-graph 里的 triangular prisms。。。这样先
solve 了 tightest constraints，然后再把其他的 constructive
地加上去。。。不过不证明一下也确实不能确定一定存在解。。。三个小时
确实搞不定。。。
小学生题目有这么难。。。除非有啥灵巧的办法吧。。。一般小学生最多
只会抽屉原理啥的。。。 |

所求的“知”，小的时候看兴趣，越大越看需要，求知的目的是problem solving
所以，每个人都是有求知欲的
小的时候，有感兴趣的东西，为了满足自己的兴趣欲望，孩子就会去“求”
大了，求学工作生活中，处处是学问因为处处有矛盾有冲突，需要problem solving
至于problem solving的能力，就看一个人的悟性和执行力了
所以，我个人认为，孩子成长的过程中
重要的不是求到多少知识，求什么样的知识
而是学习求知的能力，problem solving的能力
problem solving 的能力会跟着我们一辈子，而且会越用越顺手
大人有的时候，在孩子小的时候，过渡重视孩子对什么感兴趣对什么不感兴趣了
孩子如果对数学感兴趣，就很开心，立马觉着应该饭不私茶不饮钻研数学，才算得上求
知欲旺盛；
孩子如果对天文感兴趣，就很开心觉着高雅；如果孩子对啊猫啊狗感兴趣，就觉着低级
失望；
孩子如果对动物分公母感兴趣，立马觉着这也太早了，脑子里都想啥呢:)
anyway，我够罗嗦 |

What Motivates Us To Do Great Work?
by Jocelyn K. Glei
608629
What motivates us to do great work? It’s an age-old question. But the age-
old answers – rewards, recognition, money, stability – no longer seem to
suffice. As we’ve shifted to a knowledge-based economy, it turns out that
what drives us has shifted, too.
Recent research reveals that when creative thinking is part and parcel of
your job description, external motivation just does... 阅读全帖 |
