n*******p 发帖数: 72 | 1 真心发现system design真是太重要了,基本上现在面试被刷很大一部分都是system
desgin方面的问题。 几乎每个面试system desgin都占了很大一部分。 求版上大牛分
享一些经验,思考的模式以及相关的书籍或者网页。大家共同进步。 |

n*******p 发帖数: 72 | 2 到时没被问到三驾马车。问到三驾马车到也还好,现成的东西可以套。这个system
desgin其实主要是考察思维逻辑性,思考问题的方式,交流讨论的方式和domain
knowledge的深度。目前遇到的设计题有以下:
Twitter : 设计data visualization的系统,从数据如何存储,到如何获取数据,到
前台的显示。设计一个分布式cache的lock。
Turn: 设计一个scheduler。设计一个search engine。设计一个online ads display
system。
Box: 设计一个类似于amazon catalog的system。
Uber: 设计一个web app,可以用来在某个范围内查询各种打车的数据。
基本上一出来这种题必挂。 大牛指点。真是救命啊!!! |

k*********6 发帖数: 738 | 3 严重同意。是的。 没有经验的跟有经验的没法比,基本一个照面就跪了。 没用过真是
一点办法也没有,用过了就是不一样,只是用过一点也会很不一样,比纸上谈兵要好很
多。-二爷原话真是一个字都不用改:-)
有人说system design也考一个你没见过的,看你怎么解决一个从没见过问题的思路。
其实基本是胡扯。比如考你search里设计index,不懂inverted index,那怎么答也着不
着边,要是能面试几分钟自己想的出个inverted index,那也不用再那里被面试了,就
是几十年难得一见的大牛了。
碰到个你做过的system design题和一点没做过, 那就是天上地下。我个人觉得,
system design就是考经验。 |

2)Jogging Stroller:也有可以平躺的,空间大一点,重量轻一点,但不含car seat。

老公觉得可以直接上jogging stroller,他说后者空间大,推起来也相对舒服和灵活。

这个travel system是去年别人送给我的,当时我和老公属于最困难的时候,两个学生

不把所有的工都辞了,孩子即将出生,父母来帮忙,工作没了家里却多了人口,我们的经

都不要,我们最后塞了三十块钱就像打架一样,他们说他们是双职工(教授),而我们经
济困难,送给我们是应该的,如果我们想回报,以后就再送给需要帮助的人。
现在我们毕业成为双职工了,而这个Travel System目前又用不上(我们住二楼,搬上
搬下不方便),所以想实现原来的承诺。如果你们目前的情况和我们去年差不多(两个学
生,一份奖学金,一个自费),或者比我们还要困难,请发站内信件给我。当然如果今后
你的经济状况好转了,希望你也能转送别人。 |

x***u 发帖数: 962 | 50 宝宝11月初要出生了,最近开始研究宝宝用品,真是眼花缭乱啊,最后决定先从travel
system入手。我的理解是travel system是car seat,base和Stroller的总称。(如有
不对请指正:))
上网找了找资料,也没完全弄明白,又去店里看了看,貌似Chicco和Graco是两个卖的
比较多的牌子,其中Chicco的价格比Graco稍微贵一下,但是Graco的颜色多一些。
Chicco的travel system里基本都是keyfit30的car seat,fits 4-30lb,好像杂志上说
rear facing的时间长比较好,baby比较安全。
Graco的car seat有fits up to 22lb的,也有 up to 30lb的。22lb的car seat 叫做
Graco SnugRide; 30lb的叫做Graco SnugRide 30。
Stroller都是fit up to 50lb左右,好像差别不大。Chicco的Stroller折叠需要两只手
,Graco的有些型号只要一只手,不太确定是不是所有的都是只要一只手。
