登顶富士山

会当凌绝顶，一览众山小。

<唐> 杜甫   —— 望岳


公元2017年7月9日凌晨2点40分，这是一个我此生都不会忘怀的时刻，曾经多少次梦想着攀登富士山，此刻我终于可以大声地宣称：我征服富士山了！疲惫与兴奋相交织，酸楚与快乐相融合，这真的是只有在付出努力与艰辛之后才能体会到的成功的喜悦。距离这一激动人心的时刻已经过去一周，照片也做得差不多了，终于有时间可以回顾一下这段难忘的旅程了。Let’s kick it off!

Install Alibaba Tair

This passage mainly introduces how to install Tair, Alibaba’s own distributed key-value storage system. Because of several errors existing in Tair’s source code and out-of-date introduction documentation, we may get into trouble when installing and deploying this system in our own environment.

香港记忆

I leave no trace of wings in the air, but I am glad I have had my flight.
Leo Nikolayevich Tolstoy   —— Flying Fire


  不知不觉间，距离我去香港已经过去19个月了，原来设想的只是来香港读个一年的硕士就滚回家找工作的，没想到又多待了半年多时间。但是不管怎样，我在香港的生活终究是告一段落了。香港是一个物质的国际大都市，通过TVB，通过香港的电影，我曾对她有过无数的设想，然而直到来了香港，我才发现以前很多的看法都是不靠谱的。曾经对这种看起来金钱至上、缺乏温情的城市没有什么好感，但是这一年半却让我看到了一个不同于我脑海中印象的香港，一个充满了感情的城市。值此难眠之夜，伴着那一抹抹不舍，我想就自己的经历说一些对香港的看法。
