16:37 关于我身边的奥运 » 妮妮

1、关于奥运车辆进京体验。周末哥哥嫂嫂小表妹一干人等开车去帝景温泉度假村泡温泉。夏天泡温泉,都说我的这个创意的确很“雷人”(最新网络用词,形容一个这个东西或一件事情让人很无语,象被雷炸到一样)。出门之前,挨个给大家交代现在是奥运前期,此行去天津地界,必须带上身份证否则进不了北京云云,于是大家都激动的等待被查,体验一下奥运安保的严格程度以及是否有先进设备……出城没人查,大家纷纷相互安慰,说出城不管回城就很严格啦…… 但等到晚上进入北京收费站时,依然没人查,只看见三个警察坐在路边喝茶纳凉,看都没看我们车一眼。于是都很气愤,奥运安保工作怎么做的嘛! 

2、关于奥运志愿者。小宝老板的儿子在科大读本科,小伙子长得挺标志,之前在学校经过三次面试应征上了奥运志愿者。据老板的儿子讲,志愿者分有收入的和没收入的,他是有收入的志愿者,为一家美国公司工作(该公司可能为奥运村提供标准化客服管理),每月工资有2000元之多,学校还特批可以不用上课。更幸运的是,他的工作地点在奥运会餐厅,比那些在新闻中心(MPC)的志愿者同学们都要轻松和舒服很多。据说奥运会期间有4000多道菜云云。小宝给他的任务是把这4000道菜给吃一遍。不知道他能否完成。 

3、关于奥运的体会。上周抽空回去陪公婆吃饭,餐桌上我说马上就奥运了,一点感觉都没有?公婆说,他们深切感觉到了奥运气氛。我诧异的问体会在哪?公公向我细数来:现在运送蔬菜的大车都不让进城了,市内交通也不是特别方便了,于是超市和菜市场的各类蔬菜都凭空乘了一个奥运系数,绿叶子菜更是没有少于2元/斤的,贵了颇多。我公公有记账的习惯,多年来每天买菜明细都要记下来。而且为了迎接奥运,北京市规定各大超市的免费购物班车全部停开。想来,公婆他们比我等天天趴在写字楼里的人,还真是体会得最深些。另,还要建议公公拿历年记录给菜价做一个环比,看看奥运给老百姓的柴米生活带来多大涨幅,估计涨幅还是很“雷人”的。 

4、关于奥运搜爆犬。上周在西直门地铁外看到两名警察各牵着一条奥运搜爆犬在巡逻,搞笑的是,搜爆犬身上还披着一块跟警察一样颜色的小披风,小披风上左右居然还写了POLICE。我总怀疑自己看错了,这不是骂我们的人民警察是……啊,啊。

00:11 How to Outrun the Lions » MySQL Performance Blog

I just posted slides from a talk I gave at a Facebook application developer conference in Las Vegas this weekend. The talk is titled Outrun the Lions. Our customers run several of the top 10 applications on Facebook right now (as measured by the number of active users), and I revealed the secrets to building applications that can handle the load.

The title is a pun on the story about lions and gazelles in Africa (every day, a gazelle wakes and knows it must outrun the fastest lion; every day a lion awakes and knows it must outrun the slowest gazelle). If you’re a Facebook application developer, the lion is not your competition. It’s your users. They will love you if you do a good job. They will love you so much that the load will destroy your application, and then they’ll go away and they won’t come back. (Another speaker at the conference has the stats to prove this.)

A lot of our customers in our consulting practice are Facebook application developers, so we see the same patterns a lot. This talk was direct advice at how to avoid the problems they see as they grow. I skipped all the “you might consider these 99 options” and just said “here’s something our clients use and it works. Read the book for the full details.” If you read the slides, you’ll get an idea of how our customers have successfully scaled their Facebook applications to perform well even when they become very popular.

The reference to the book was because the company who sponsored the conference (Offerpal Media) gave everyone free copies of our new book High Performance MySQL 2nd Edition. Not only was this very nice of them to do, hopefully it’ll help them avoid trouble with their applications.
