非诚勿扰

上周五的时候和任斐还有大一的两个学妹去美嘉看了这部电影。
看的时候就觉得秦奋的台词实在是太精彩了,这么好的口才找不到女朋友才真是让人奇怪了。当电影拍到海口的世纪大桥与滨海大道时还让我小小激动了一番。舒淇和徐若瑄都拍得很漂亮,看得时候任同学在旁边就说要他是秦奋就答应徐若瑄演的台湾妹了。冯导的讲故事水平也非同一番,一个包袱接着一个包袱地丢,以征婚作为线索,北京->海口->杭州->北京->北海道,线路非常清晰,丝毫不让人觉得时间的流逝,恍惚之间电影已经打上了尾声。
电影把北海道拍得非常漂亮,漫山的向日葵,沿海酒店,没有尽头的山间公路,路边的小教堂……散场的时候就听到旁边一位女士说:那一大片太阳花实在太漂亮了。北海道真是个神奇的地方,在很多影视作品里都会听到这个名字,我印象中那儿的雪非常大,总会给人一种很浪漫的感觉。像一个五六十年前的城市,让人感觉不到现代化的气息,这让我想起了《不能说的秘密》里主角居住的城市,我在想这样子的地方现在真的还存在吗?
更神奇的是,回去后回味这部电影,竟深深地被片中的气氛所感动。乌托邦式的美好而不可及的感情,”人在这,心不在这”,”我的心将会留一块位置给他”……
上一次我记得的看完电影后味道逐渐升华的是《罗马假日》,于回味中感慨那种无忧无虑如香草冰激凌般干净的感情。
找时间还想再去看一次《非》。
周六的学院元旦晚会,台上的同学,我很想带她一起去看电影。
周日看了好早以前下载的Randy Pausch’s the Last Lectrue,具体内容就不在这儿说了,请自行Google之。
印象最深的是他反复说的一句话:那些墙的存在是为了那些阻止对梦想不够坚定的人。
昨天晚上数据库课程设计答辩,助教人非常非常nice,答辩的过程也比较顺利。
回想这次课程设计,收获还是不小的。第一次写网页,还是用文本编辑器写得,也就是传说中的手写PHP网页。 我会继续努力让”讲座网”早日上线的。
2008年就要过去了,想列几部年内看过得不错的电影。无奈就记得彭浩翔的《破事儿》与《AV》,前者搞笑,后者励志,实乃不可多得的佳品。谁知道最近有什么比较不错的粤语片请在下面吱一声,谢了。
祝大家元旦快乐,这个假期就不休息了,大作业、考试、实验室、GRE,发现生活已经没有end了~~~~~~

关于vista下apache+php+mysql+phpmyadmin的安装与配置

先说一下动机:今天决定把数据库的大作业从linux下搬到windows来做,原因是实在没剩多少时间了。在windows下,想写的时候就不用重新启动机器了,在某种意义上还是会节省许多时间。
关于网上这方面介绍的文章已经非常多了, 不论是中文的还是英文的,但是因为机器环境也是千变万化,所以每次我配的时候都是东看看西看看。这次把过程记录下来,以后要是再有机会配置的话参照起来也比较方便,当然如果有相同配置的网友看到了,也希望这篇文章能够给一些帮助。
先说一下环境,
操作系统:Windows Vista Ultimate
Apache_2.2.11+php_5.2.8+mysql_5.1.30+phpmyadmin_3.1.1
apache:
先给一个官方的下载页面:http://httpd.apache.org/download.cgi,在页面里选中” apache_2.2.11-win32-x86-openssl-0.9.8i.msi“进行下载。
下载后双击进行安装,我选择的安装位置是”D:/web/apache2.2″,选一个短一些的文件路径,以后配置也比较方便,基本上就一直next直到安装结束,除了domain那个页面填”localhost”。
vista安装会提示出错,需要一些额外的工作,造成错误的原因是因为安全权限的原因服务不能正确安装。
解决方法:在 命令提示符环境下进入”D:/web/apache2.2/bin”,输入”httpd -k install”,就可以安装了,之后在原路径输入”httpd -k start”,启动apache服务器
因为我的机器UAC 是关掉的,所以这一步就忽略了,不过以以防万一还是象征性地敲一下命令
之后貌似还会提示另一个错误,大意是说80端口不能绑定,可能是IIS造成的。在浏览器重输入”http://localhost”,看能不能提示”It works”,可以就说明服务器已经运转起来了。如果可以运转就不用管那个警告了,如果不行的话google一下警告的信息,网上相关的文章跟海一样。
php:
还是先给一个官方的下载页面:http://www.php.net/downloads.php,注意这里不要选择installer,选择zip package下载自行解压安装。
打开下载后的压缩文件,将文件解压到”D:/web/php”。
这里需要配置一下apache服务器
首先新建一个文件夹”www”在”D:web”下,然后在打开d:apache2.2conf下的httpd.conf 文件
找到”DocumentRoot”,把后面跟着的句子改成”D:webwww”,这个代表你在浏览器下输”localhost”,服务器找到的默认目录,当然以后你把localhost改成别的域名,你输入改了的域名就自动会找到这个目录。
在一大群LoadModule下面添上下面两句话:
LoadModule php5_module “D:/web/PHP/php5apache2_2.dll”
PHPIniDir “D:/web/PHP”
另外找到一大娶AddType,在下面添这句话:
AddType application/x-httpd-php .php
这样子你的apache服务器启动以后就可以跑php了。
然后找到”DirectoryIndex index.html”,修改为”DirectoryIndex index.php index.html”
意思是将默认主页的文件名设置为先寻找index.php,再找index.html。什么意思呢?比如你输入http://localhost,apache会先找你网站目录(这里我们设置为”D:webwww”)下的index.php文件并显示结果,如果文件不存在接会去找index.html。也就是为什么我们平常上网只用输入域名而不用输入指定显示哪个文件,因为服务器会自动指向默认的主页文件。
之后保存httpd.conf,然后重启一下apache服务器。
重启方法有两种,第一种打开开始->程序->apache下的apache服务管理器,打开一个图形界面点”restart”,另外一种方法是通过命令提示符来到”D:webapache2.2bin”,输入”httpd -k restart”,感觉后面一些比较专业,我比较细喜欢,因为如果出错的话还可以看到错误提示信息。
我们测试一下,打开D:webwww文件夹,新建一个文件,文件名为:index.php,打开文件,输入:
<?php phpinfo(); ?>
然后打开一个浏览器,输入http://localhost,看能不能显示php的信息,可以的话就代表我们前面一系列的配置都成功了。还没完,接下来配置MySQL
MySQL:
先给一个官方下载页面地址:http://dev.mysql.com/downloads/mysql/5.1.html#win32,选Windows Essential(x86)进行下载。
下载后点击安装文件开始安装,其中路径选择D:webmysql。
安装完毕后选择配置MySQL,选standard,输入你的root账号密码(一定要记得),然后点下一步让它配置完,到此MySQL就配置完毕了。
接下来的工作是要配置PHP让它能够集成MySQL的模块。
首先打开php的目录将php.ini-dist文件复制一份并改文件名为php.ini。
打开该文件,找到extension_dir,将前面的分号(如果有的话)给去掉,代表这句话不被注释,将”=”后面的路径改为”D:webphpext”,这一步是指定php的动态扩展目录。
然后把下面几句的前面的注释分号去掉
extension=php_gd2.dll
extension=php_mbstring.dll
extension=php_mcrypt.dll
extension=php_mhash.dll
extension=php_mime_magic.dll
extension=php_ming.dll
extension=php_mysql.dll
上面是去掉后的样子…
保存php.ini文件
然后要把php目录下的 libmysql.dll文件copy到windows/system32下
重启apache服务…
测试一下,在浏览器输入http://localhost,看phpinfo()是否显示有MySQL模块。在浏览器按ctrl+F,输入mysql看找不找得到,找得到就说明配置成功了。
一般如果你按我的步骤做下来应该是可以的,如果不行的话问题就很复杂了,建议还是上googlegoogle一下
phpmyadmin:
到这儿我们的工作已经完成90%了,OMG你竟然坚持看到了这里。这就是open source,一切都得靠你DIY,虽然麻烦了一些,但还是蛮锻炼能力的,尤其是遇到莫名其妙的问题的时候,如何在强大的搜索引擎上找到你需要的信息,也是需要技巧的,呵呵。
先给出官方下载页面:http://www.phpmyadmin.net/home_page/downloads.php
phpmyadmin其实就是一个图形化的MySQL管理软件,不过是用php写的,所以需要将上面三个步骤都完成后才能使用它。
言归正传,将下载后的压缩文件打开,将里面的文件夹整个解压到D:webwww下,然后将文件夹的名字改成phpmyadmin。
在浏览器中输入http://localhost/phpmyadmin
如果打开就说明OK了,账号输入root,密码输入安装mysql时我让你记住的那一个,就进去了。
如果失败的话…
如果提示的信息是说php没能连接mysql的话,请参照配置MySQL的段落;如果提示的不是上述信息,google吧…
到这里配置就完成了,如果每一步我给的测试条件都通过了,享受用php写网页的快感吧。提示一下北航用jsp写网页的同学,据身在美国的章鱼同学日志的说法,那边是没人用jsp的,大家平常还是尽可能地多接触open source吧。偷偷告诉大家,北航是有一个open source社团的哦,点击链接打开。
欢迎大家与我交流啊,如果有不明白或者拍砖的同学在下面留言就好了,我会尽我这个菜鸟的最大力量给大家解答的。

我不会写标题了

在实验室写了一个下午软件工程文档,为了GPA,这学期软工的每一次作业都尽可能地精益求精。因为我是项目小组里的主要开发者,这次《概要设计说明书》自然落到了我的肩头上。
格式,思考,参考,胡诌,对着老师给的满分95的评分准则,任何能让文档看上去更正式更完整的方法我都用上了。
其实对我来说这并不是一件很无聊的事情,我还是蛮喜欢做这种非常格式化的工作的,只是蛮耗时间罢了。
说到时间,昨晚我无情地拒掉了今天下午任*的K歌宴。连续两天晚上12:30后从实验室往回走,早上7:00以前从宿舍往实验室走了。两门大作业,GRE的单词与作文,实验室永远做不完的工作,科实的工作(我很想找时间给大一的学生再开一次沙龙),时间总是感觉不知不觉地流走。这个学期似乎又已经接近了尾声,回去的机票貌似还挺贵的,元月28号还得回来上寒假的新东方,再短的时间都得回,不知道大三的暑假会发生些什么事情,抓紧能跟家人聚在一起的时间,因为最近身边发生的一些事情,更觉得此事是如此的珍贵。
Google Reader的Recommendation功能真的很好很强大,据说是根据用户的阅读习惯来给你推荐你可能喜欢的源。一开始用的时候订了好几个PPMM的blog,结果就一直给我推这方面的blog。这一看不行啊,连机器都觉得我好这口,于是马上把相关的blog全都退订了。
之后又开始给我推IT资讯与新闻相关的blog,结果很快就信息过剩了,所谓信息爆炸就是没有信息,于是又退订了一些。Recommendation有一个很好的功能就是可以把它推荐给你的blog拒掉,这样子下次列表刷新(一、两天一次)的时候这个blog就不会显示出来了。
最近订阅了一些北航在美国留学同学(比如大章鱼PP学姐)的blog,过了一段时间后,它竟然开始给我推一些类似的blog,而且大部分都还是cs的。有种如获至宝的感觉,我总喜欢从别人的故事中找到对自己的激励。让我印象很深的是前天晚上看到的一个复旦(从字里行间判断出来的)的学姐,今年过去的。拒了CMU/LTI(CMU中对我来说最梦幻Institue)的AD,拿offer去了WISC,而且貌似本科只上了三年(从字里行间判断出来的)。校ACM队,大三就开始发各种会议的paper,貌似都是我现在很”想”去做的事情。
另外看到的两个blog更猛,一个发到了WWW上,另一个发到了AAAI上,忘了是哪个几乎每年都参加ACM的International Final了,搞CS的,嘿嘿…

个人觉得上面每所学校都是大牛特牛,尤其注意CMU,UCLA,USC&Purdue这四(我不会数数了)所学校的offer人次。貌似会让别的学校的人很羡慕的样子,因为只要能保持在年级的前30,基本就不用愁了。
让我想起了前几天在太傻上看的一个帖子,大意是说被对方学校拒的原因是因为X名以外的学校不予考虑,然后那个人感到很愤慨,觉得应该”英雄不问出处”云云,然后那个帖子似乎还被版主加了好几点威望。
当时为了和谐,没有在上面留言,因为我觉得这个只能怪那位同学自己,怪他在高中的时候没有好好努力,考上一个好的学校。这几天看到我们学院一个学长的日志,我理解他的意思是我们现在处于一个”无所畏惧”、可以拼命的年级。我觉得他说得很好。
有时候可以听到有人所”趁大学不好好玩,以后就没有机会了”,相反,我的看法是”如果现在不好好拼,以后就真没有机会了”。其实人的一辈子是一直在做各种各样的选择,选择”出国”还是”读研”,选择今天晚上”打dota”还是”多写几行代码”,选择”追女生”还是选择”晚自习多做几道题”,选择”看动画片”还是”选择做奥数题”。这里没有谁对谁错(比如”小时候回家看《圣斗士》”永远是我不能忘记的快乐时光),但是这里有一个你做的选择是否是迈向你的目标的问题。
感觉人生的轨迹就像一颗分叉的树,每个时间段都会根据你做的事情走向不同的树枝。在你很年轻或者很小的时候,你位于树的根节点,你所可以做得改变是最多的。随着年龄的增大,不同的人会随着不同的分支走向不同的轨迹。如果这时候你发现你年轻时的选择是不正确的,你要付出比另外一些人多得多的精力去改变,可是很多时候你会发现有些事已经没法改变了。比如上面那位同学他既不能让对方学校录X名开外的学校也不能让自己的学校冲进X名以内。就算有可能,付出的代价与他高中的时候努力一把考进X名以内的高校相比,哪个更容易做到一些呢?
所以,看到上面那个录取名单就不足为奇了,有的是这个省的状元,有的是IOI的金牌获得者,有的在你学加减乘除的时候就在敲if/else了。
呵呵,所以那个表格权当看看消遣就好了,我大学以前的时光还是过得非常开心的:D
说一些轻松的,最近看的几部电影各一句话评一下:
The Dark Knight:小丑如神话般
007:看完有种被耍了的感觉
Wall-E:Pixar越来越有深度了
梅兰芳:经典台词,“那要得爷乐意”

作文小组第二次issue写作作业

TOPIC: ISSUE94 – “Universities should require every student to take a variety of courses outside the student’s field of study because acquiring knowledge of various academic disciplines is the best way to become truly educated.”
WORDS: 577 TIME: 01:40:31 DATE: 2008/12/7 22:45:21
As society’s develop, usually we should be able to manage various knowledge to get a good job. But at the same time, we also need some scientists who study deeply in one field.
I think it is necessary to give students a chance to study knowledge from a variety of fields when they in Banchelor or Master course. We know that in many universities students are obiliged to get credit from the courses which are outside the student’s field, which I think could results from at least three reasons.
Firstly, as technology is more and more complex today, the student who only get knowledge in a narrow aspect is less and less competitive. Most time the employ requirements of company, especially in I.T industry, would be consist of some different parts, which is more than tech skills.
Secondly, most of the students, especially in China, don’t have a idea whether they are really interested in the major they pick at the time they get into university. Because of the heavy pressure of study we have to take when we are in high school, most of us don’t have enough time to consider carefully what is suitable for us mostly. But as we can take a variety of course in university, now we can have a chance to access to what we really want.
Last but not the least, the people who achieve success always manage a variety of knowledge. Our country’s founder, Chairman Mao, was a famous exponent. He was a politics, but also known as strategist and poet. In Europe, Da Vince and Newton were also honored by people for they made great contribute to big development in different fields. I don’t think this is just a coincide. The people who are good at different fields usually could get more various views on one thing than the people who are only addicted into a narrow field. This is because the resources that the former could get inspiration from are more than the latter.
But, it is not sensible to encourage students to take knowledge as more various as possible. No matter whether student is going to do research or not after they graduate, basic skill and knowledge inside their own field is indispensible.
If you’d like to take Ph.D Degree, the depth of knowledge you get into in your field really does matters. I know in HongKong Univ. of Techonology and Science, Ph.D candidates only take four cources in their first year while Master candidates would take nearly ten courses. Because Ph.D’s task is to promote the research in some finite field, which requires that someone have to get deep knowledge in base. As a result, they don’t have much time to take these various cources. It is the same to ungraduate students. Of course we should get a wide range of knowledge during our college time, but we have not to forget what is the most important. Sometimes students go too far away to get back, which may result to they can’t get a satisfied job after they graduate from school.
Now we can get a conclusion that aquiring knowledge of various field should be based on a strong knowledge in our major field. Before you are good at your major field, it is meaningless to take many various courses. But, it is not enough to have a good knowledge in one narrow aspect in the modern society, you also have to explore your interest.

改了buaa-alun的文章,改得不好,相互交流吧 呵呵issue 42 “Because learning is not a solitary activity but one that requires collaboration among people, students of all ages will benefit academically if they work frequently in groups.”

As the society’s developing, collaboration
替换词:cooperation coordination has played an important role in academic research, where people from different fields couldwould更好些 inspire each other. Bio-computer science is such an example which makes interaction between biology and computer science. Inspired by structure of DNA, scientists come up with the idea that we can design the architecture of computer in a new way, which was called bio-computer. (第一段就用例子有点头重脚轻,不妨放后边看看)Apart from research, commercial company is also encouraged to hire the people who are good at teamwork. Because today the complexity of work is much more than before, Nowadays, because of large amounts of complicated accomplishments ,which are much more than before,no one could(would) learn everything. But with collaboration we can take advantage of every distinct one, which results to something amazing.(which would results in something around us becoming special and amazing.)

But I don’t think(as far as I am concerned, It seems a little unilaterat to consider ) that learning in groups is the only way we can acquire knowledge. Different people prefer to think in different way. Most of my friends tend to study with a silent environment. Noise from other people could make them interrupted. Famous physician Albert Einstein liked to stay in the roof of his house without leaving for a few days, when he tried to figure out some mysterious theory. Actually the idea from others will always confuse you, which make(makes) you can’t calm down. It’s easy to understand people who work in quiet is more efficient than that(those who) work in noise.


In addition, I have to say the idea(The second reasons to support my standpoint is ) that children of all ages work frequently in groups is not sensible. I think (
替换词:consider , give thought to ,turn over in my mind evaluate )education should give children a chance to improve the ability of thinking alone, which is quite important(which plays a significant partment in children’s future). If they don’t have much chance to solve problem alone when they are very young, it’s easy to make them feel more likely to depend on others when they grow up. That’s the reason why your junior school teacher always tells you not to copy homework from others but finish it by yourself.

What decides whether collaboration is good for learning or not? I think that should be considered in different definitions of “learning”.

Firstly, learning could result toin study basic knowledge you don’t know before. At this time, to study alone may be more efficient than (studying ) in crowd. Because there is nothing you can share with others before you know .
In the other hand, learning also means that inspiration made by people from different academic fields. With collaboration, people could get fresh air from the place where they never step in before. Like Newton says: stand on the shoulder of giants. The ability of how to learn from others also need us cultivate during our academic life.(放到一段里)
At conclusion, what we need is not just collaboration or just solitary. We need both of them when we’re learning. We need solitary space to get our own perspective and collaboration could broad our perspective at the same time.

提纲:
第一段:学习中的合作确实是件好事啊
第二段:但学习有时候也需要个人的空间
第三段:对于学习基础知识的小孩子,他们需要培养自己思考的能力
第四段:合作好不好,关键在我们对”learning”的定义
第五段:合作、独立都要

总体写得还可以,思路很好,但是语言过于简单, 加些长音节次较好,中间段落过多 最好是56段论

改得不好, 希望提些意见, 互相交流

What decides whether collaboration is good for learning or not? I think that should be considered in different definitions of “learning”.
Firstly, learning could result to study basic knowledge you don’t know before. At this time, to study alone may be more efficient than in crowd. Because there is nothing you can share with others before you know it.
In the other hand, learning also means that inspiration made by people from different academic fields. With collaboration, people could get fresh air from the place where they never step in before. Like Newton says: stand on the shoulder of giants. The ability of how to learn from others also need us cultivate during our academic life.
At conclusion, what we need is not just collaboration or just solitary. We need both of them when we’re learning. We need solitary space to get our own perspective and collaboration could broad our perspective at the same time.

presentation@est

est: English of Science & Technology
这是这学期选的一门选修课,中文名叫《科技英语》,我的理解就是教你如何读paper的。课上老师要求每个学生要做一次presentation,题目是本专业一篇学术论文的abstract。
其实第一个星期老师布置这个任务的时候我就开始想我要选哪一篇paper。我想找一篇比较有意义,但又不会离下面听众太远的,最好是能给大家讲明白的。
The Anatomy of a Large-Scale Hypertextual Web Search Engine
于是我找到了上面这篇paper。这是10年前(1998)Google创始人Sergey Brin & Larry Page 发表在WWW Conference上的一篇文章,文中描述了他们发明的一个叫做google的搜索引擎,号称是世界上第一个可以处理大规模数据的搜索引擎,同时因为利用了现存网页中超文本的结构,可以将搜索结果以一种比较令人满意的方式进行排序。
基于这个叫做google的搜索引擎,他们从斯坦福休学,创立了一个叫做Google的公司,后面的故事大家都知道了。
some words about Research
前几天参加Sun科技日的时候听了一位清华教授的报告,是关于Semantic Web的。
报告完之后跟他又聊了将近一个小时,其中提到了关于做研究。
研究与商业的差距:
研究是可以建立在”假设”上的,因为研究可以超前于当今的技术。相当于你走到前面去了,如果随着时代的发展,你的”假设”被证明是错的,那你的一切结果都没有意义了;可是如果你的”假设”被证明是正确的,那你已经早早地走在别人前面了。
让我想到了:一将功成万骨枯,做研究貌似也是这样的。
而商业,是要讲利润的。对于公司来说,你的理论都么好,多么创新,最终都要转回到money上来。为什么现在各种各样的网游层出不穷,因为这已经成为了一种非常固定的盈利模式。当今互联网固定的盈利模式,广告,搜索和IM。在中国,最大的两家网络公司,腾讯和百度,就是典型的例子。为什么微软花那么多钱在他家的Live Search和MSN上?原因就不言而喻了。
非常惊诧于10年前,那个互联网还不是那么普及的一个年代。两个大学生就已经看到了搜索引擎的重要性,最终通过此他们发明了adWords,成就了Google今天的霸主地位。充满智慧的同时,也非常幸运,能将研究成果与盈利模式完美进行结合的人,问世上又有几呢?

饥饿状态

这是那天听到的一个名词,饥饿状态,大致说的意思是:优先级最低的任务始终无法被执行,因为总会有优先级比它高的事情出现,比如CPU处理中的线程管理。
这让我想到了自己的计划管理,每周列出了很多项目,可是发现,几个星期过去了,有的事情一次也都没有碰过。因为总会有别的事情加进来。比如:我一直计划着一个星期调查一所大学的相关信息,比如办学宗旨、计算机学院招人标准、学费等等,听起来一个星期并不会抽出很多时间来做这么一件事情。可是,就这样一个月、两个月过去了,这个计划始终停留在MIT上(我的计划是按排名从前往后做)。
实话说,现在我仍然没有很好的解决方案。
另外一个问题,也是关于计划安排的,就是,做事情应该是并行的好几件事情都做呢?还是这个星期或者这几天专门把一件事情攻下来,再去做下一件。比如读书,是同时读好几本,每周每本都读一些,还是这一到两周专功其中一本呢?
我一直处于探索的状态,感觉两种方法都不是很理想。
第一种:并发机制,这种方式的缺点是,同一本书两次阅读间隔可能会比较长,很容易这次读的时候把上一次看的东西都给忘了。
第二种:单线程,这种方式的缺点是,不可能将一段时间完全用来做这么一件事,总会有别的事情加入进来,打断你。
所以比较困惑现在,感觉单线程的方式效果会比较好,可是很容易把许多事情堆起来。现在感觉比较好的解决方法是,设立一个优先级,先把一定要做完的事情给做完,其余时间专攻一本书。可是问题又出来了,优先级,谁高谁低,什么事情重要,什么事情不重要,子子孙孙无穷匮也~~~
