Each round you flip 3 to 5 pieces, thus changing the color of their upper side from black to white and vice versa. The pieces to be flipped are chosen every round according to the following rules:
GMP
前天看见同学分享的一个微软面试题:求 y = sin(e^5120) 的值 然后就在网上搜了一下， 就找到了GMP这个玩意儿， GNU多重精度运算库（英语：GNU Multiple Precision Arithmetic Library，简称GMP或gmpal）是一个开源的任意精度运算库，支持正负数的整数、有理数、浮点数。它没有任何任何精度限制，只受限于可用内存。GMP有很多函数，它们都有一个规则的接口。它是C语言写成的，但用为其他很多语言做包装，包括Ada，C++，C#，OCaml，Perl，PHP和python。 GMP主要运用于密码程序和搜索，和计算机代数系统。 GMP的目标是成为最快的大数运算库， GMP是GNU项目的一部分，它在GNU宽通用公共许可证下发表。 GMP在许多计算机辅助代数系统中用于整数运算，如Mathematica和Maple。 GMP需要使用GNU（GCC编译器套装）编译。

今天上arch wiki的查资料时候, 又一不小心把arch打成arc, 因为arc和arch发音太近, 所以有的时候手快一点就容易打错, 突然灵光一闪去Linost瞄了一眼arclinux.org这个域名注册情况, 结果发现居然没有人注册(表示看不懂arc-linux.org倒是有人注册了), 然后立马下单,下完单一看傻了眼, 手速快了点给注册成arclinux.com了, 完了不得不再把org域名注册一遍, 今年在域名上面真是很花了些银子… 然后就是设置Google Analytics, 一直折腾到现在都没有搞好, 代码放到网页上去过后Status始终是Tracking Not Installed, 起初发现自己script后面忘记写type=, 后来加上去了一直到现在还是没有receiving data, 这夜深人静时刻, 果真是把自己折腾得醉了.

So, I got something new. When it was my first day to be in campus, I think I gonna do something cool, but it never comes to me what exactly it is and how it will be, I didn’t think too much about it, the only idea in my mind is that: I gonna be cool(so that I can change the whole world). Obviously, I was just naive . Time is such a great thing, looking back to my past years, it always comes to me that how funny and ridiculous I was, even if I have been an adult and collge guy and had so much mind of my own(I think), the power of time never decrease, it seemed to be a long way to fight with it. Whatever, it’s an end, and a start, too. To be continued…
