快乐SAS
3月30开始了在ebay的实习，之后一直纠缠在考试论文和实习中，博客也从此凉在了一边。据说四个月能养成一个好习惯，以后每周两篇日志将成为我的日常任务。
这两周考试基本搞定，一下子轻松了好多。除了学校施工的噪音和常有的一点点困惑，木得连烦心事都没有。开开心心得写程序学统计。地铁里见人玩俄罗斯方块，想想现在这生活也是差不多。不断有各种各样的task下来等着你处理，学习、生活、工作、爱情、未来。要顺顺利利地把它们搁到合适的地方。只要心不乱，并没有什么难的。
周末还是在图书馆过，暑期依然坐满了人。明天又是周一，继续学习、工作，平静而踏实的生活。还是会把大部分时间放在SAS上，技术上争取有个好的基础吧～读研已经一年，有那么点紧迫感。ebay给我最大的福利就是身边那些pro，热爱生活，乐于助人的同事。感谢他们并向他们学习。
下面这篇文章蛮经典，被引用了好多次，大致可以看出哪些是SAS的基本功。其中我学的不好的地方也就是这个假期的努力方向。但SAS毕竟是个分析软件，统计思维远比技术重要。下面的文章只是focus on SAS base, but if you can't know well about the tools, you can't do analysis well.
