读水浒

小说的前半部分比较精彩, 用浓重笔墨栩栩如生的讲述了几位梁山好汉 - 林冲, 鲁智深, 武松, 杨志,穿插着交待了柴进, 史进, 晁盖等人智取生辰纲. 晁盖为梁山打下了第一桶金, 坐第一把交椅. 故事到这就出现了转折. 突然冒出个宋江. 令人难以置信, 怎莫江湖上就这好的名声. 按照当时的通信水平, 一个县吏, 实在不知道怎得就人人都想拜他做大哥. 然后就莫名其妙的收了诸多江湖好汉. 上了梁山, 虽然坐第二把交椅, 但是俨然是大哥. 次次都是他领着弟兄出去火拼. 次次都大获全胜, 还能收不少弟兄. 晁盖在山上的地位岌岌可危, 终于要出山一次. 就这一次, 就在曾头市被射死. 宋江自然坐了第一把交椅, 虽然晁盖死时交待的条件也不管用了, 也从侧面反映了晁盖的地位. 小说的高潮部分就是108条好汉大聚义. 其实里头凑数的混混不少, 特别是72地煞星. 最后打方腊, 真正是天有定数, 稀里哗啦的几乎都死光了. 小说里还有个事实, 就是当时人吃人肉好像很普遍啊.

Phone interview by Google Beijing

I applied engineer position in Google Beijing. After a couple of days, got a call to setup the first round phone interview. The turn around time is really fast. Within a week, I got 3 phone interviews from them. I am now waiting the result. The interviews are all conducted in English, except the first one, the second half session is in Mandarin. I feel they are all oversea scholars base on their English fluency. The technical questions cover a very wide range, but are more focused on data manipulation, processing and storage. Google definitely has an interview questionnaire. They pick up from the set and ask. I didn't meet any tricky questions, but some questions are very academic.

去Suntec Expo附近观察了一圈

因为开IMF World Bank会议, 果然是戒备森严啊. 平常从Marina Sqaure去Suntec Expo的那个过街天桥全都封了, 只能有通行证的过. 天桥底下Temasek Blvd全部封了, 架起隔离铁丝墙, 停着几辆防暴警车. 家乐福的那个入口站了两个荷枪实弹的士兵.大概想象了一下, 周围的高楼顶上肯定有狙击手盯着. Suntec一带的商店肯定生意受影响不小.

Singapore Marina Area

IMF@Suntec

IMF and World Bank annual meeting will be held at Suntec Expo from Sep 10 to Sep 20. The streets around this area is closed since this Sunday 10PM. This morning I drove to work. Nice, so quite the streets near Suntec are. Lots of guys in uniform, police, civil defence, somehow I feel like VIP. There will be some protestors who are against finacial globalization during the meeting. IMF proposed to allow them protest outdoors. Singapore has refused. They can allow protest in the designated area indoors.
