才发了20+篇，太低产了，远远不及我在人人网上发的数目啊！

果然我更适合灌水而不是知识沉淀。

唔，有语云：“忙的适合有货没时间写，闲的时候有空没货写”。

我工作基本算是定下来了吧，现在应该有更多的时间可以搞自己喜欢的东西，嗯啊，我要在南京回来之前订下下面100天的计划，玩好+学好，多写博客，争取过个快乐的大四！

这是一个太大的问题，可以说上千言万语。

对于我现在的博客而言，现在只有一个读者，那就是我自己。

软件工程有句名言“吃自己的狗食”，如果我自己都不看自己以前的博客，那还指望谁来看呢？

我想在自己的博客里看到什么？

这是个好问题，我觉得应该包括：

1.成长的轨迹，不同时代的思考
2.学习过的东西，曾经我也有很多技能，后来都丢失了，若有博客的记录，是不是方便有朝一日能找回来
3.个人的展示，这不限于博客的形式，个人wiki的形式或许也不错，我一直想做，应该要在本科毕业之前完成。展示我曾经做过的项目，写过的文章，等等

下一阶段博客就应该包括这样的东西，不要太在乎暴露自己的无知，我要见证自己的成长。

The Turing Award Winner John Hopcroft will visit MSRA on Oct.24th 2012.
It is honored to attend the presentation he gave to the undergraduate interns.

The topic covered in the presentation:
- John share his personal experience
- For a senior undergraduate student, how to make right choice in the right time
- The comments for current undergraduate and graduate education
- Suggestions to students about how to develop their core skills to meet the future needs

整个对话大概持续1个小时，John先说了20min,然后就话题讨论和QA,结束之后和交大ACM班的同学圆桌，我就没法参与了。

全过程里我记了大概两页笔记，摘录精华如下：
1. 关于选择： You only one life to live , so do the job you really love doing, don't concentrate on your payment
2. 关于热爱： If you do what you love to do, you'll work 16h a day, if you don't you will only work 8 hours
3. 关于兴趣： 多选几门课，找到自己的兴趣点
4. 关于传道授业： Every Thusday afternoon, I provide free food for my students and talk about their research problems（ps:我现在的mentor这点上很像，每周请实习生吃一次饭，大家带着问题来）
5. 关于道路： If your mentor bring you to the machine learning, data mining... you are on the good way

还有对MSRA的实习生项目的优劣进行了探讨，比较了中国和美国大学的不同，并对学习给出了一些建议。

the bio of John
John Hopcroft
John Edward Hopcroft (born October 7, 1939) is an American theoretical computer scientist. His textbooks on theory of computation (also known as the Cinderella book) and data structures are regarded as standards in their fields. He is the IBM Professor of Engineering and Applied Mathematics in Computer Science at Cornell University.

He received his master's degree and Ph.D. from Stanford University in 1962 and 1964, respectively. He worked for three years at Princeton University and since then has been based at Cornell University.

In addition to his research work, he is well known for his books on algorithms and formal languages coauthored with Jeffrey Ullman and Alfred Aho, regarded as classic texts in the field.

He received the Turing Award – the most prestigious award in 1986. The citation states that he received the award "for fundamental achievements in the design and analysis of algorithms and data structures." Along with his work with Tarjan on planar graphs he is also known for the Hopcroft–Karp algorithm for finding matchings in bipartite graphs. In 1994 he was inducted as a Fellow of the Association for Computing Machinery. In 2005 he received the Harry H. Goode Memorial Award "for fundamental contributions to the study of algorithms and their applications in information processing." In 2008 he received the Karl V. Karlstrom Outstanding Educator Award "for his vision of and impact on computer science, including co-authoring field-defining texts on theory and algorithms, which continue to influence students 40 years later, advising PhD students who themselves are now contributing greatly to computer science, and providing influential leadership in computer science research and education at the national and international level."

In 1992 John Hopcroft was nominated to the National Science Board by George H.W. Bush.
In 2009, he received an honorary doctorate from Saint Petersburg State University of Information Technologies, Mechanics and Optics.

Hopcroft is also the co-recipient (with Jeffrey Ullman) of the 2010 IEEE John von Neumann Medal, “For laying the foundations for the fields of automata and language theory and many seminal contributions to theoretical computer science.”

2012年寒假去海南单车环岛的
开了另外一个博客 http://806ad.sinaapp.com/ 两人共同维护
当时的设想是当做wiki一样共同编辑
事与愿违
最后算是完全废了
突然发现这个博客的memcache服务每个月还要消耗掉30个云豆，sae的memcacah实在是太贵了！
于是就把这个博客卸载掉了
