发帖数: 84 | 1 不论是投机也好还是投资也好，其实任何一个标的投资人心里都清楚是有泡沫的，而且
主观上是认同有泡沫的，没有泡沫的话挣钱真的很难。只是投资人希望买到的标的是优
良资产，相对价格比较低，让人们相信未来泡沫会更大。
但是所谓优质资产这个东西就值得玩味了。因为这个概念是相对的，在不同时期都是不
一样的。比如过去房贷低首付低的时候在中国房子算是优质资产之一，而现在随着银根
缩紧加上限售限购这样的政策风险房子相对就不如高利贷有赚头了，那么以今天的中国
为例，缺钱的老实人就是优质资产了。
所以看待bit币不能静态的看待它所谓的泡沫，因为讲泡沫也要讲周期，绝对的看待泡
沫是不可取的，要相对的看。今天大家都知道中国的房市有问题，如果是九十年代的中
国虽然房价已经开始高企，但是离所谓的泡沫其实是是指危险的泡沫还早，因为那时候
还是房市周期的初期。现在看待bit币不仅要看它自己的泡沫还要和别的标的横向作比
较。
所以我们把视角从bit币稍微拉开一点点，先看看别的资产。实际上以今天看资本市场
。泡沫到处都是，投资人投资是希望买到便宜的标的。可是便宜的标的在哪里呢，在09
年在10年而不在16年17年。道理很简单... 阅读全帖 |

Conventional display devices use 8-bits per color channel (or 24-bits per

发帖数: 68 | 19 我看到这个问题1337在下面链接：
http://www.leetcode.com/2011/08/reverse-bits.html#comment-4958
我看不懂下面这个：
if (lo ^ hi) {
x ^= ((1U << i) | (1U << j));
就是说如果lo位置的bit 和 hi 位置的bit不一样，就switch between them or
reverse each one. 我不懂的是
x ^= ((1U << i) | (1U << j));
如何做到的？
==> swap these two bits when they are different, meaning flip 0 -> 1, or
flip 1 -> 0, this can be done by XOR 1:
0 ^ 1 = 1
1 ^ 1 = 0
i.e., XOR 1 will flip the original bit |

楼主写的很好的，把bit放在金融层面看，观点鲜明。 bit有没有泡沫这个现在真的难
说，没人知道其价值到底有多少。 但是目前大量资产泡沫却是实际存在的。 我感觉
bit除了是一种投资或者投机品外， 还有它的内在技术特性。这点像龙头科技公司的股
票，不同于债券之类。 人类以前从来没有过区块链这样的基于计算机和互联网诞生的
新事物。也许bit是对未来金融模式的一次探索实验，失败也是大概率事件。但它给人

北京理工大學（BIT）國防實驗室目前正在利用飛彈防禦技術，研發一種高敏銳雷達，
能夠探測到2公里外拍動翅膀的蚊子，分析識別蚊子的種類、性別、大小、飛行方向與
速度，還有牠們是否已經吸食過血液，並加以追蹤，可以作為防治蚊蟲的強力工具。
根據香港《南華早報》報導，世界衛生組織（WHO）報告顯示，每年有超過100萬人因蚊
子叮咬，帶來瘧疾等傳染性疾病而喪命，死亡人數甚至比所有戰爭罹難者的數量還高出
許多。研究人員表示，控制害蟲是十分艱鉅的挑戰，因為它們幾乎來去幾乎不會留下痕
