1. Write a function that takes as input integers P and Q and returns P to
the power of Q. Note any assumptions you make and the complexity of the
algorithm. We expect you to do better than O(Q).
2. Write a function that takes as input an array of 1 million integers,
such that 1 ≤ x ≤ 10 for every element x in the array, and returns the
sorted array. The sort does not need to occur in-place. Obviously you ... 阅读全帖 |

"White women prefer white men to the exclusion of everyone else--and Asian
and Hispanic women prefer them even more exclusively. These three types of
women only respond well to white men. More significantly, these groups'
reply rates to non-whites is terrible."

搜狐 [0条评论,查看/发表评论]
科技网站readwrite本周发表评论文章称，对宅男而言，谷歌眼镜的问世让互联网
增强技术以及未来式可穿戴设备不再遥不可及，作为第一代半沉浸式计算机体验设备，
如果其能获得成功，那么将预示着更多类似设备的大规模出现。
这种期待是可以理解的，如果我们口袋中能够接入互联网的计算机可以改变我们的
世界，那么想象一下这些可以戴在脸上的设备能够做些什么吧。从增强现实技术游戏到
未来手术，其前景都让人们兴奋不已。虽然很新潮，不过凡事有利有弊，谷歌眼镜也有
让人不舒服的一面。
似乎每一件新事物都会至少有一个与社会或者政治有关的担忧，人们会担心个人隐
私会不会受到谷歌眼镜的侵犯，除此之外，还有5个在社交场合中需要谷歌眼镜用户注
意的问题。
1.偷拍异性
除了专家和学长，有一类人肯定也非常希望能够使用谷歌眼镜，那就是偷拍狂。虽
然使用智能手机早已经可以让人们在公告场合对陌生人拍照和录像，不过用手机的摄像
头对着某人从礼仪上来说是非常不礼貌的，而使用谷歌眼镜就消除了这一尴尬，有评论
家指出，这些假想都是基于人们会受到异性的吸引。... 阅读全帖 |

发帖数: 13752 | 13 我觉得920的设计思路有问题。下面这个评论说的中肯。感觉上，920有点一个
committee搞出来的东西，各种想法妥协后混在一起，搞出来个臃肿的产品。
http://readwrite.com/2012/11/27/nokia-lumia-920-not-the-windows
Releasing a device that is noticeably bulkier than the iPhone 5 or the
latest Galaxy flagships is not a very good way to compete with Apple and
Samsung. Worse, Lumia line keeps getting bigger, not smaller. The original
Lumia 800, announced in October 2011, was a joy to hold. It had a little
heft to it but the body was sleek and pleasant. The Lumia 900, rele... 阅读全帖 |

don't tell me java performance has increased by three times in less than 2
years. my own benchmark in my own job also showed similar performance
difference. another big problem is that a java server program has to use a
lot more memory than necessary to achieve reasonable latency under GC. |

把苹果的命给革了以后，却发现革命群众不是那么好带的．
Never has a tweet been more true, or potentially more disastrous for a
vendor. Years ago Google's Andy Rubin, stung by Steve Jobs' criticism that
Android wasn't truly open, tweeted that anyone could fork - i.e., modify -
Android, making it "open" in the truest sense of the word.
Unfortunately for Google, many OEMs took Rubin at his word.
Today, Google's Android business is booming, but it's clear that Android
