看到一篇说cs申请的文章,分享之

http://www.cs.cmu.edu/~harchol/gradschooltalk.pdf
cmu是cs最好的学校,看了之后我就觉得有点不想学phd,其实~唉~也很难说
然后就觉得我想学cs去cmu就基本上完全没有希望的。。。fml虽然我明白自己的水平。
我应该是要去考sub的。。。fml,想学cs就必须考了,尤其本专业不是cs的。抱着万一的希望看了这篇文,要考啊。啊啊啊啊啊。。。fml

最近看了一下关于反汇编的一些书,pediy论坛不错,但是没有深入去看。

说一个google的技巧

很多时候会因为各种各样的原因看不了很多网页(我不是说被那个和那个谐,而是说因为站点自身的问题),这个时候googlecache就特别给力了,只要在google搜索栏中打入cache:www.kengni.com就可以看到因为某些原因看不到的kengni.com了。
事实上,像火狐这种给搜索引擎设置个关键字就可以的浏览器直接输入g cache:kengni.com就行
P.S. 才知道w3cschool.com被那个和那个谐了,fml。又,google cache也是被和那个谐了的。

搜集到教材一本 Management information systems

不看不知道啊 一看吓一跳啊,这破书薄薄的居然在amazon上卖173.12$,还是打了79折的。。。。在美国活不起了,不过原版是彩色的很漂亮。闲话不说了,链接在最下面。

迅雷会员试用体验

今天突然心血来潮,买了一个月的迅雷会员试试,十分钟之后幸庆自己只买了一个月的。。。这玩意对我没有用啊。。。。fml

事实证明,如果本身到迅雷服务器速度慢,那么就不会快T^T,迅雷可能在教育网没有服务器的。好伤心。
