今天队姐从深圳回家，先飞天津，再坐火车，然后我带她去五大道转了转。后来有一个传统艺能是骑车子拉行李箱，然后因为天津这边的路况实在是太太太太太垃圾了，所以队姐的行李箱轮子也被拉坏了。“也”的原因是我去年去参加 xcpc 比赛的时候也这么干，于是行李箱轮子就坏了一个。
有点对不起队姐的说……
今天简单看了看 Zero Zero3 Zero++ 的原理，Alltoall 分层通信 的一些动画演示，学到了一些“一言不合就分块”的思想。理论上应该记一些笔记，但是我没有看过代码，不知道富卡的公司工程师们写的代码是什么样的，回头看两眼再说吧。可能学算法竞赛的时候教练教的是如果你觉得你看懂了一个算法，你应当能自己实现一遍。但是事实上我从来没达到过教练的这个要求。
最近看了超级巨大多老友记，我觉得片头曲很洗脑，每次都不舍得跳过。大概记录一下歌词吧。话说回来马上就六级了啊。
I'll be there with you
"I'll Be There For You (Theme From Friends)"
So no one told you life was gonna be this way
Your job's a joke, you're broke, your love life's D.O.A.
It's like you're always stuck in second gear
When it hasn't been your day, your week, your month, or even your year, but
I'll be there for you
(When the rain starts to pour)
I'll be there for you
(Like I've been there before)
I'll be there for you
('Cause you're there for me too)
You're still in bed at ten and work began at eight
You've burned your breakfast, so far things are going great
Your mother warned you there'd be days like these
But she didn't tell you when the world has brought you down to your knees that
I'll be there for you
(When the rain starts to pour)
I'll be there for you
(Like I've been there before)
I'll be there for you
('Cause you're there for me too)
No one could ever know me
No one could ever see me
Seems you're the only one who knows what it's like to be me
Someone to face the day with, make it through all the rest with
Someone I'll always laugh with
Even at my worst, I'm best with you, yeah!
It's like you're always stuck in second gear
When it hasn't been your day, your week, your month, or even your year
I'll be there for you
(When the rain starts to pour)
I'll be there for you
(Like I've been there before)
I'll be there for you
('Cause you're there for me too)
I'll be there for you
I'll be there for you
I'll be there for you
('Cause you're there for me too)
