***********************************
CR's Take
This model from Audio-Technica delivers very good sound quality and very
good active noise reduction, but the combination on/over-the-ear fit may be
cramped for those with bigger ears. These headphones have a closed design,
so they will muffle some external sounds apart from the active noise

发帖数: 1269 | 7 square的硬件是极小的部分，主要还是软件，跟paypal差不多的。
关键是它从一开始就做mobile，已经占了一定份额，收费又比paypal低，就算
迟早paypal要占领大部分市场，square也已经占了一批小用户。
google的mobile payment还远没到payment的地步。就算他们做出来了，跟paypal
同时推出，看看google checkout vs. paypal就知道大致结果。而且我总觉得，
如果你是固定paypal用户，只要他们的mobile payment function做得不是太烂，
应该还是prefer用paypal mobile，因为毕竟是money movement。
dropbox其实也是做软件，这年头都用aws，大家都只做应用了。但是重点也来了，
如果你只做应用，那你凭什么觉得你就比skydrive/icloud/google cloud强很多
呢？cloud storage的用户stickiness跟payment比差很多吧？ |

求实时 Top K 的做法有很多，但是具体说起来很长，你可以搜一下这样一些算法：
Space Saving, Efficient Count, Lossy Counting, Sticky Sampling, Hash Count.
(如果搜不到对应的论文，就加 Top K Frequent Items / Elements 之类的关键字)
这里我不展开说这些算法是怎么做的，你自己去搜。或者上 Big Data 的班（http://www.jiuzhang.com/course/4/）。我这里主要说一下 Filter 的这个部分怎么设计和整个架构是什么，因为即使你有一个 Realtime Top K 的 Service，你依旧需要设计一下 Filter。

发帖数: 15836 | 25 I have been using Brita pitcher for the past more than a year. The
difference between using it and without using it is day and night. The water
becomes much fresher and clearer after using it, while before using it, the
water really tastes like a lot of stuff in it and sticky. Now I drink a lot
of water directly from my pitcher, which should be much more convenient
than boiling it.
The cost for replacing filter is not negligible, considering I have 3
pitchers in total and I have to replace filte |

发帖数: 15836 | 37 Before filtration, my water also tastes stale and sticky, it looks not very
clear in a glass cup either. After filtration, it tastes much better and
feels much better in mouth. It is also much more clear when put side by side
in glass cup with tap water.
Those high-end filtration systems of course should do much better than the
lowest end water filtration that I am using. But I think it should be
worthwhile to try it before you buy the much more expensive ones just to
make sure you don't over do |

Surprisingly statistics from both NOAA , and Cityrating.com show that Los
Angeles has, on average, a slightly higher relative humidity than, say,
Albany, New York. It is hard to believe because the air in L.A. does not
have that hot, sticky feeling that air in east coast cities has. Perhaps
this phenomenon is because the air in Los Angeles usually comes off the
ocean and is cool compared to air over land masses where the sun has had
time to warm it. Until I resear... 阅读全帖 |

If the seepage on your basement wall is not so well below ground, one of the
things you can try is,
1. Dig up along the basement wall to the depth where the seepage occurs.
Make the drench 4' wide.
2. Waterproof the exterior wall, I'll just use the stuff sold in HD or Lowes
