生命的震撼

每当看这样的东西,总会有一种震撼的感觉

最后的几张照片,病人已经是卧床不起。是啊,总觉得很久很久的东西,不过才是短短的18年……

Thanks to 大黎黎's blog~~以下为转载。

一个摄影师从1979到1997。18年。pola相机。每天一张照片。
第一张是1979年3月31日,最后一张是1997年10月25日。

后头的就没了。
因为,1997年10月25日那天,拍照片那人死在病床上。 他的朋友把他生前拍的照片整理了出来,放在网上。
18年都在里面
http://photooftheday.hughcrawford.com/

要求每个被点名的人找到自己出生那天的照片贴出来。 

我找到自己生日那天的照片~~

忽然有种感触,如果自己在此刻做了一个决定――将一件事情坚持下去。

一定会感觉要做好久好久,因为自己总是认为:此生好久好久。

当他决定每天拍一张照片的时候,是不是也以为要拍好久好久?

原来,不过十八年而已……

Dave Raggett's Introduction to HTML

这是一个简单的html语言的介绍,没有仔细看,需要的时候可以查一下。


This is a short introduction to writing HTML. What is HTML? It is a special kind of text document that is used by Web browsers to present text and graphics. The text includes markup tags such as <p> to indicate the start of a paragraph, and </p> to indicate the end of a paragraph. HTML documents are often refered to as "Web pages". The browser retrieves Web pages from Web servers that thanks to the Internet, can be pretty much anywhere in World.

Many people still write HTML by hand using tools such as NotePad on Windows, or TextEdit on the Mac. This guide will get you up and running. Even if you don't intend to edit HTML directly and instead plan to use an HTML editor such as Netscape Composer, or W3C's Amaya, this guide will enable you to understand enough to make better use of such tools and how to make your HTML documents accessible on a wide range of browsers. Once you are comfortable with the basics of authoring HTML, you may want to learn how to add a touch of style using CSS, and to go on to try out features covered in my page on advanced HTML

p.s. a good way to learn is to look at how other people have coded their html pages. To do this, click on the "View" menu and then on "Source". On some browsers, you instead need to click on the "File" menu and then on "View Source". Try it with this page to see how I have applied the ideas I explain below. You will find yourself developing a critical eye as many pages look rather a mess under the hood!

For Mac users, before you can save a file with the ".html" extension, you will need to ensure that your document is formatted as plain text. For TextEdit, you can set this with the "Format" menu's "Make Plain Text" option.

This page will teach you how to:

  • start with a title
  • add headings and paragraphs
  • add emphasis to your text
  • add images
  • add links to other pages
  • use various kinds of lists

If you are looking for something else, try the advanced HTML page.

Start with a title

Every HTML document needs a title. Here is what you need to type:

<title>My first HTML document</title>

Change the text from "My first HTML document" to suit your own needs. The title text is preceded by the start tag <title> and ends with the matching end tag </title>. The title should be placed at the beginning of your document.

To try this out, type the above into a text editor and save the file as "test.html", then view the file in a web browser. If the file extension is ".html" or ".htm" then the browser will recognize it as HTML. Most browsers show the title in the window caption bar. With just a title, the browser will show a blank page. Don't worry. The next section will show how to add displayable content.

Add headings and paragraphs

If you have used Microsoft Word, you will be familiar with the built in styles for headings of differing importance. In HTML there are six levels of headings. H1 is the most important, H2 is slightly less important, and so on down to H6, the least important.

Here is how to add an important heading:

<h1>An important heading</h1>

and here is a slightly less important heading:

<h2>A slightly less important heading</h2>

Each paragraph you write should start with a <p> tag. The </p> is optional, unlike the end tags for elements like headings. For example:

<p>This is the first paragraph.</p>

<p>This is the second paragraph.</p>

Adding a bit of emphasis

You can emphasize one or more words with the <em> tag, for instance:

This is a really <em>interesting</em> topic!

Adding interest to your pages with images

Images can be used to make your Web pages distinctive and greatly help to get your message across. The simple way to add an image is using the <img> tag. Let's assume you have an image file called "peter.jpg" in the same folder/directory as your HTML file. It is 200 pixels wide by 150 pixels high.

<img src="peter.jpg" width="200" height="150">

The src attribute names the image file. The width and height aren't strictly necessary but help to speed the display of your Web page. Something is still missing! People who can't see the image need a description they can read in its absence. You can add a short description as follows:

<img src="peter.jpg" width="200" height="150"
alt="My friend Peter">

The alt attribute is used to give the short description, in this case "My friend Peter". For complex images, you may need to also give a longer description. Assuming this has been written in the file "peter.html", you can add one as follows using the longdesc attribute:

<img src="peter.jpg" width="200" height="150"
alt="My friend Peter" longdesc="peter.html">

You can create images in a number of ways, for instance with a digital camera, by scanning an image in, or creating one with a painting or drawing program. Most browsers understand GIF and JPEG image formats, newer browsers also understand the PNG image format. To avoid long delays while the image is downloaded over the network, you should avoid using large image files.

Generally speaking, JPEG is best for photographs and other smoothly varying images, while GIF and PNG are good for graphics art involving flat areas of color, lines and text. All three formats support options for progressive rendering where a crude version of the image is sent first and progressively refined.

Adding links to other pages

What makes the Web so effective is the ability to define links from one page to another, and to follow links at the click of a button. A single click can take you right across the world!

Links are defined with the <a> tag. Lets define a link to the page defined in the file "peter.html" in the same folder/directory as the HTML file you are editing:

This a link to <a href="peter.html">Peter's page</a>.

The text between the <a> and the </a> is used as the caption for the link. It is common for the caption to be in blue underlined text.

If the file you are linking to is in a parent folder/directory, you need to put "../" in front of it, for instance:

<a href="../mary.html">Mary's page</a>

If the file you are linking to is in a subdirectory, you need to put the name of the subdirectory followed by a "/" in front of it, for instance:

<a href="friends/sue.html">Sue's page</a>

The use of relative paths allows you to link to a file by walking up and down the tree of directories as needed, for instance:

<a href="../college/friends/john.html">John's page</a>

Which first looks in the parent directory for another directory called "college", and then at a subdirectory of that named "friends" for a file called "john.html".

To link to a page on another Web site you need to give the full Web address (commonly called a URL), for instance to link to www.w3.org you need to write:

This is a link to <a href="http://www.w3.org/">W3C</a>.

You can turn an image into a hypertext link, for example, the following allows you to click on the company logo to get to the home page:

<a href="/"><img src="logo.gif" alt="home page"></a>

This uses "/" to refer to the root of the directory tree, i.e. the home page.

Three kinds of lists

HTML supports three kinds of lists. The first kind is a bulletted list, often called an unordered list. It uses the <ul> and <li> tags, for instance:

<ul>
<li>the first list item</li>

<li>the second list item</li>

<li>the third list item</li>
</ul>

Note that you always need to end the list with the </ul> end tag, but that the </li> is optional and can be left off. The second kind of list is a numbered list, often called an ordered list. It uses the <ol> and <li> tags. For instance:

<ol>
<li>the first list item</li>

<li>the second list item</li>

<li>the third list item</li>
</ol>

Like bulletted lists, you always need to end the list with the </ol> end tag, but the </li> end tag is optional and can be left off.

The third and final kind of list is the definition list. This allows you to list terms and their definitions. This kind of list starts with a <dl> tag and ends with </dl> Each term starts with a <dt> tag and each definition starts with a <dd>. For instance:

<dl>
<dt>the first term</dt>
<dd>its definition</dd>

<dt>the second term</dt>
<dd>its definition</dd>

<dt>the third term</dt>
<dd>its definition</dd>
</dl>

The end tags </dt> and </dd> are optional and can be left off. Note that lists can be nested, one within another. For instance:

<ol>
<li>the first list item</li>

<li>
the second list item
<ul>
<li>first nested item</li>
<li>second nested item</li>
</ul>
</li>

<li>the third list item</li>
</ol>

You can also make use of paragraphs and headings etc. for longer list items.

HTML has a head and a body

If you use your web browser's view source feature (see the View or File menus) you can see the structure of HTML pages. The document generally starts with a declaration of which version of HTML has been used, and is then followed by an <html> tag followed by <head> and at the very end by </html>. The <html> ... </html> acts like a container for the document. The <head> ... </head> contains the title, and information on style sheets and scripts, while the <body> ... </body> contains the markup with the visible content. Here is a template you can copy and paste into your text editor for creating your own pages:

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<title> replace with your document's title </title>
</head>
<body>

replace with your document's content

</body>
</html>

Tidying up your markup

A convenient way to automatically fix markup errors is to use HTML Tidy which also tidies the markup making it easier to read and easier to edit. I recommend you regularly run Tidy over any markup you are editing. Tidy is very effective at cleaning up markup created by authoring tools with sloppy habits. Tidy is available for a wide range of operating systems from the TidyLib Sourceforge site, and has also been integrated into a variety of HTML editing tools.

Getting Further Information

If you are ready to learn more, I have prepared some accompanying material on advanced HTML and adding a touch of style.

W3C's Recommendation for HTML 4.0 is the authoritative specification for HTML. However, it is a technical specification. For a less technical source of information you may want to purchase one of the many books on HTML, for example "Raggett on HTML 4", published 1998 by Addison Wesley. XHTML 1.0 is now a W3C Recommendation.

Best of luck and get writing!

遭遇潜规则:一个北大女研究生的读研噩梦

才知道这件事闹了这么大,已经诉诸法律了。转载以bless。

北医的研究生。


    如果不是发生在我身上,我做梦也不会想到,曾经让我觉得无比自豪的北大竟然会发生这样的事!--道貌岸然的导师竟然想用潜规则逼我就范!如果我"聪明"一 点,我肯定已经顺利毕业了,如果我不是把做人的清白看得比所谓的学业更重的话,这一切就不会发生!先声明一点,我是在没有办法的情况下才说出真相的,面对 一个无耻之徒和一伙不负责任的纵容者,我真的只有用这种方式来进行最后的抗争。

    2007年7月25日,我像往常一样来到实验室,下午进导师办公室向他汇报工作进展及讨论后续工作安排事宜。汇报了一些工作后,导师示意我把门关上说话, 让我坐在他对面。突然导师对我说:"姑娘,你很聪明!好好干,前途大好啊!"然后伸手摸了一把我的脸,我愣住了,一时间说不出话来。他看我吓得僵住了,就 说:"你是个聪明姑娘,我很喜欢你,你知道吗?"我几乎是颤抖着说:"哦,我知道老师您对我们都挺好的......""但我对你更好一些,你能感觉得到 吗?"他打断我。我也不知说什么,只好傻笑,说实在的,这个导师对我们这些学生实在都不怎么样,应该只有差和更差的区别,哪里有好和更好?但我只能附和 说"您对我们都很好"。导师又问:"下次带你去开会,就带你一个人去,敢去吗?"我赶紧说:"谢谢老师,不过我也得有工作成绩才能去开会啊,我会更加努力 的。""有男朋友吗?""有。"我赶紧说。他沉吟了一下,又笑着说:"你有男朋友也没关系,我还是很喜欢你,你害怕吗?"我能说什么?只好再次愣住不做 声。"平时跟男朋友在一起都干些什么啊--我知道你们年轻人啊,还是要多注意身体,"他顿了顿,目光闪烁不定的说,"有些事是很美啊,是不是?"我觉得越 来越不对劲,如坐针毡不知找什么借口逃走才好,我明显感到自己脸上的肌肉不自然地发抖,而导师仍然笑得捉摸不定,这时听见他说:"我想抱抱 你......"天哪!我觉得脑子一炸,后面他还说些什么就完全听不见了,我一直告诉自己别误会导师,别误会导师!可是终究被无情的现实粉碎了,我来不及 多想,惊慌的说了句:"老师我先出去了!"就夺门而逃。说实话,我一直很尊敬他,他有妻子,有两个女儿,大女儿都上初中了,在外人看来完全是一个幸福的家 庭,可是!后来我镇定之后真想去跟他说:"老师,我很尊敬您,您指派我干什么工作都行,但是请您尊重您的学生!" 可是终究没有这个勇气,只好装作什么也没发生过。但是心里其实非常的忐忑不安。当天晚上,我给自己最信任的朋友打电话,说了这些,我害怕的问:"要是下次 他真要带我去开会怎么办啊?我要总是拒绝的话,他不让我毕业怎么办?"朋友安慰我:"他是你导师,他不让你毕业他有什么好处呢?自己学生不毕业自己脸上也 无光啊。"我这才稍微定了定心。

    从那以后,我的日子就开始变得提心吊胆,去导师办公室说话也不敢关门,每次都是以最简短的话语汇报,后来还特地找了个男同学充当我的男朋友到实验室来陪 我。导师似乎也觉察到了什么,恼羞成怒之下他一反常态,开始在公共场合呼斥我,动不动就找茬骂我,我想其实他最想骂的是我"不识抬举"吧。作为学生,我只 好忍着,只希望早一点毕业就可以彻底摆脱这个噩梦。

    然而,战战兢兢的日子没过多久,我最担心的事情终于发生了。

    2007年9月26日是我们开题的日子。三个学生,我是第二个讲,讲到中途放出两张RT-PCR图片(开题幻灯片报告)时,导师突然喊"停!",然后就 问:"你这是什么时候做的?我怎么没见过?"我愣了,他怎么会没见过?我们所有实验结果都是要给他过目的,我定了定神,回想了一下,回答是6月到7月间做 的,然后他又说没见过。我讲完后,回到座位上,心里很不安,不知他又打什么算盘,待开题结束后,我赶紧去公用电脑上找原始数据,因为我知道以他的习惯是肯 定要问的。但是--原始数据不翼而飞了!我们实验室人员很杂很乱,没有自己的个人电脑,所有数据都在公用电脑上,大家建立自己的文件夹,我找过自己的文件 夹后,又把其他人的文件夹也找了一遍,还是没有,我当时并不以为然,觉得把实验重复一下就得了,也不难。这时导师果然来问我了:"你把原始数据拿来给我看 看。"我轻轻的说:"没了。""没了??!!"他咆哮起来!我愣了,心想不至于这么小题大做吧?我把情况告诉他后,他马上说:"你没有原始数据就是造假, 你这事没完!"然后扬长而去。我又呆住:最多说我不慎遗失数据啊,这怎么跟造假扯上关系了?

    第二天,导师把我叫到办公室,关上门说:"再给你一次机会,要么你承认造假,态度好的话我可能就算了,要么就打报告把你交给学位分会处理。"--这叫什么 机会!两条都是死路啊!而且,我为什么要承认我没做过的事情?我坚决不答应。他说那么我就不客气了。--说到此处还有一个相关话题:就是我的某位师姐,她 的确是什么也没做出来,其学位论文中的全程数据均是造假,还是导师他自己告诉我们的,后来经核实确实如此。而他一直瞒而未报,因为北大有规定,所带的研究 生学位论文有造假行为的导师会停招研究生甚至开除--当时我气得发抖,就很冲动的说了一句:"某某是真造假你倒不管,我这没造假你却要我承认!"
    可能我的态度激怒了他,他打开办公室门,不再听我说,自己走了出去。并且马上把报告打到了教研室,说我不能提供原始数据,有造假嫌疑云云。教研室主任让我 说明情况,我说我可以重复实验,如果质疑造假的话,应该是对数据本身在科学的角度就不可能做出来,难道原始数据丢了的就是造假?况且一个开题报告,我有什 么利益动机去在这样一个不值得造假的地方去造假呢?教研室主任说,那你去重复出来吧,这是你跟你导师沟通的事,我也不想管太多。
    我很快就重复出来了实验结果,因为这实在只是一个很简单的实验。但是,当几个老师组成调查小组时,没有人关心我重复的结果,每个人都说:我们不管你重复 没,或是能否重复,只问你原来结果到哪去了。--最后,他们写了一个决定:我在开题时所用的结果在原始记录中找不到。并要求我签字。我想,这个结果用调查 吗?我早就告诉他们找不到了啊,我说:"怎么不说我已经重复了呢?如果这样写就全是对学生不利的一面啊,怎么对学生有利的就不写呢?"--但没有人搭理, 并且硬性要求赶紧签吧。我想他们也没有说我造假,看样子不签也不行,就签了。

    后来我就这个问题请教了业内的很多德高望重的老师,当然也包括肿瘤医院的许多老师,他们都觉得导师说我造假简直是个天大的笑话,在他们看来,"开题幻灯片 报告"仅仅是由学生本人向各位老师汇报的一个拟做课题实验的设想,以及初步预实验的工作汇报,仅代表之前几个月探讨性实验的结果,并不是实验研究的结果, 仅仅是一个幻灯片发言汇报,并没有写文字材料汇报,更没有写成学术论文。作为学生的发言汇报幻灯片,有错误或设计有误、数据有误,应该是允许进行修正、补 充或做改进的。虽然我没有找到原来的图片,但我已经及时对此结果进行补充,这应该是允许的,所以根本不存在我弄虚作假的说法。

    可悲的是,医院处理这件事的人不知出于什么原因竟然完全置这些于不顾,成了纵容这个悲剧的帮凶!

    不得不提到的就是另一个叫hyz的老师,我们管他叫h老师,他总管我们院的研究生。事发以后又过了一个月,就是10月底,到了我们交开题报告总结的日子, 需要导师签字。之前因为导师打了报告,而且又压根对我重复的结果不予理会,我跟他已经很久没说过话了。我当时猜想他可能不会给我签字,但仍然抱了一丝希望 去碰运气,不过结果在我的预料之中,他拒绝签字:"你这开题有问题,我都已经打报告到学术委员会了,等他们的处理意见吧,我不能给你签。"我站了一会,也 不知说些什么好,只好离开了去找h老师,因为按照正常程序他可以进行干预,责令导师要么给出确凿理由来,要么签字。
    但是h老师看了我一眼,慢悠悠的说:"你导师不签字为什么啊?那他不签我也不能拿刀架他脖子上让签啊。"我说:"h老师,可是这个报告总结,我作为学生来 说能完成的部分已经完成了,不是我消极懈怠自己不做而延误的,如果现在因为导师不签字而误了时间,那到时怎么办啊?"h老师还是他一贯的口吻:"导师的责 任导师负,学生的责任学生负。你放心,等事情清楚后,学生的权益还是得保障的,你什么时候签了字来我都算你九月底提交的。"
    我觉得这样子处理心里没底,只好又找到教研室主任,说导师不给签字怎么办啊?主任说那得你们自己沟通去啊。我觉得无望,但是至少h老师的话我记下了,就是说,只要什么时候能签了来就算完成了,这样又稍稍定了心。
    从那以后,我只好自己在实验室做实验,以前虽然也没有人指导,但需要用什么东西还是方便的;现在没有人指导,东西却不能用了。我开冰箱拿东西,由于我们的 冰箱是超过5秒钟就开始自鸣的,我当时在最底层拿东西,拿了2分钟左右,冰箱已经在自鸣了,这在平时是所有人都有的情况,可导师就冲过来说:"你在干吗? 你别做了!你别在这毁坏实验室仪器!"我尴尬得不知手往哪放好,全实验室的同学都不知道怎么回事,以为我犯了滔天大错了;还有一次,我打开水龙头冲废液, 这同样是再平常不过的举动,结果导师又冲来了:"你干吗!你在这浪费国家水资源!"冲我破口大骂了一通。--每天经受这样的精神折磨,终于让我溃退了,我 已经没有办法在实验室里呆下去,只要一看到他我就吓得浑身颤抖!而且他又给h老师打报告说一定不能让我待下去了,因为我经常在做损害实验室的事情。h老师 于是建议我别去了,说先缓一阵,很快就能把事情处理掉,保障我学生的权利。我于是就不去实验室了--他终于达到了把我赶出实验室的目的。

    到了2007年12月底,我已经不被允许进入实验室达三个月了,由于我一直在申诉,北医的领导交待肿瘤医院赶快处理,不能把学生吊着――我至今感激这位领 导――于是肿瘤医院给了我处理结果,说是给我换个导师,同时要延期毕业,要给处分。我问给处分的理由和证据是什么,他们拿不出理由和依据,但就是要给处 分,因为我向上级申诉影响了医院的声誉!天哪,我只是通过正当的途径行使我一个学生正当而弱小的权利,难道这也有错吗?

    2008年1月初,万般无奈之下,我给院长写了封信,希望能得到公正待遇,请求院长帮我解决问题,院长很快答复说委托副院长去调查了。第二天,就有教学办 工作人员给我电话,说是导师提交了一份我的开题报告,让我过去看看后签个字;我问这些材料是给谁看,答曰院长,我大喜过望,心想终于有出头之日了。由于我 开题时交的是电子版,对于这份不是由自己打印的打印版就检查了下有无缺页和错页,赶紧签了字,还特意把自己的重复实验数据粘在了上面,好给院长过目。
    万万没想到的是,又过了两个月,我终于被告知,我签字的打印版,上面的数据跟当时实验室另一个人的数据(当然也由导师提交)一模一样!这回我不是涉嫌造假了,我涉嫌抄袭!我想我尊敬的导师一定很满意:你不是说我没证据说你造假么?我这就给你个证据!
    我也终于有机会得见所谓的由我签字的打印版,上面的两张rt-pcr数据与我原来的数据的确像极了,只有放在一起才看得出差别来。可是导师说了:你签了字的东西还想不认?--终于坐实了我的造假之说。
    今年六月份,因为我一直不肯屈服,医学部通知我,对我的最后处理是:延期毕业,换导师,不处分,但会给一个我能接受的警示性的处理。虽然这不是最公正的一 个结果,但是对于我一个无依无靠的学生来说,这个结果也还算可以接受--本来我已经落实了接收单位,并且可以落户北京,但这一切都有了变数--即使这样, 我也还是咽下了这枚苦果,我甚至还有几分庆幸,因为我毕竟通过斗争保住了我的清白!只是万万没有想到的是,才过了半个月,他们竟然出尔反尔,又做出了要给 我处分的决定,我真的是想崩溃了!我在想,难道我只能以极端的方式结束我在北大的生活吗?

    到现在我什么也不怕了。如果我不幸牺牲的话,那么我一定是被迫害的,请记住:我的导师叫张志谦!

Google week: 101 tips, tricks and hacks

English version of the previous post~

1. The best way to begin searching harder with Google is by clicking
the Advanced Search link.

2. This lets you search for exact phrases, "all these words", or one
of the specified keywords by entering search terms into the
appropriate box.

3. You can also define how many results you want on the page, what
language and what file type you're looking for, all with menus.

4. Advanced Search lets you type in a Top Level Domain (like .co.uk)
in the "Search within site of domain" box to restrict results.

5. And you can click the "Date, usage rights, numeric range and more"
link to access more advanced features.

6. Save time – most of these advanced features are also available in
Google's front page search box, as command line parameters.

7. Google's main search invisibly combines search terms with the
Boolean construct "AND". When you enter smoke fire – it looks for
smoke AND fire.

8. To make Google search for smoke or fire, just type smoke OR fire

9. Instead of OR you can type the | symbol, like this: smoke | fire

10. Boolean connectors like AND and OR are case sensitive. They must
be upper case.

11. Search for a specific term, then one keyword OR another by
grouping them with parentheses, like this: water (smoke OR fire)

12. To look for phrases, put them in quotes: "there's no smoke without fire"

13. Synonym search looks for words that mean similar things. Use the
tilde symbol before your keyword, like this: ~eggplant

14. Exclude specific key words with the minus operator. new pram -ebay
excludes all results from eBay.

15. Common words, like I, and, then and if are ignored by Google.
These are called "stop words".

16. The plus operator makes sure stop words are included. Like: fish +and chips

17. If a stop word is included in a phrase between quote marks as a
phrase, the word is searched for.

18. You can also ask Google to fill in a blank. Try: Christopher
Columbus discovered *

19. Search for a numerical range using the numrange operator. For
example, search for Sony TV between £300 and £500 with the string Sony
TV £300..£500

20. Google recognises 13 main file types through advanced search,
including all Microsoft Office Document types, Lotus, PostScript,
Shockwave Flash and plain text files.

21. Search for any filetype directly using the modifier
filetype:[filetype extension]. For example: soccer filetype:pdf

22. Exclude entire file types, using the same Boolean syntax we used
to exclude key words earlier: rugby -filetype:doc

23, In fact, you can combine any Boolean search operators, as long as
your syntax is correct. An example: "sausage and mash" -onions
filetype:doc

24. Google has some very powerful, hidden search parameters, too. For
example "intitle" only searches page titles. Try intitle:herbs

25. If you're looking for files rather than pages – give index of as
the intitle: parameter. It helps you find web and FTP directories.

26. The modifier inurl only searches the web address of a page: give
inurl:spices a go.

27. Find live webcams by searching for: inurl:view/view.shtml

28. The modifier inanchor is very specific, only finding results in
text used in page links.

29. Want to know how many links there are to a site? Try link:sitename
– for example link:www.mozilla.org

30. Similarly, you can find pages that Google thinks are related in
content, using the related: modifier. Use it like this:
related:www.microsoft.com

31. The modifier info:site_name returns information about the specified page.

32. Alternatively, do a normal search then click the "Similar Pages"
link next to a result.

33. Specify a site to search with the site: modifier – like this:
search tips site:www.techradar.com

34. The above tip works with directory sites like www.dmoz.org and
dynamically generated sites.

35. Access Google Directory – a database of handpicked and rated sites
– at directory.google.com

36. The Boolean operators intitle and inurl work in Google directory,
as does OR.

37. Use the site: modifier when searching Google Images, at
images.google.com. For example: dvd recorder site:www.amazon.co.uk

38. Similar, using "site:.com" will only return results from .com domains.

39. Google News (news.google.com) has its own Boolean parameters. For
example "intext" pulls terms from the body of a story.

40. If you use the operator "source:" in Google News, you can pick
specific archives. For example: heather mills source:daily_mail

41. Using the "location:" filter enables you to return news from a
chosen country. location:uk for example.

42. Similarly, Google Blogsearch (blogsearch.google.com) has its own
syntax. You can search for a blog title, for example, using
inblogtitle:<keyword>

43. The general search engine can get very specific indeed. Try
movie:<name of film> to look for movie reviews.

44. The modifier film: works just as well!

45. Enter showtimes and Google will prompt you for your postcode.
Enter it and it'll tell you when and where local films are showing.

46. For a dedicated film search page, go to www.google.co.uk/movies

47. If you ticked "Remember this Location" when you searched for show
times, the next time you can enter the name of a current film instead.

48. Google really likes movies. Try typing director: The Dark Knight
into the main search box.

49. For cast lists, try cast: name_of_film

50. The modifier music: followed by a band, song or album returns music reviews.

51. Try searching for weather London – you'll get a full 4-day forecast.

52. There's also a built-in dictionary. Try define:<word> in the search box.

53. Google stores the content of old sites. You can search this cache
direct with the syntax keyword cache:site_url

54. Alternatively, enter cache:site_url into Google's search box to be
taken direct to the stored site.

55. No calculator handy? Use Google's built in features. Try typing
12*15 and hitting "Google Search".

56. Google's calculator converts measurements and understands natural
language. Type in 14 stones in kilos, for example.

57. It does currency conversion too. Try 200 pounds in euros

58. If you know the currency code you can type 200 GBP in EUR instead
for more reliable results.

59. And temperature! Just type: 98 f to c to convert Fahrenheit to Centigrade.

60. Want to know how clever Google really is? Type 2476 in roman
numerals, then hit "Google Search"...

61. You can personalise your Google experience by creating a Google

62. With a Google account there are lots more extras available. You'll
get a free Gmail email account for one...

Google sites and new features.

68. "Custom Search" enables you to create a branded Google search for
your own site.

69. An active, useful service missing from the list is "Personalised
Search" – but you can access it via www.google.com/psearch when you're
logged in.

70. This page lists searches you have recently made – and is divided
into categories. Clicking "pause" stops Google from recording your
history.

71. Click "Trends" to see the sites you visit most, the terms you
enter most often and links you've clicked on!

72. Personalised Search also includes a bookmark facility – which
enables you to save bookmarks online and access them from anywhere.

73. You can add bookmarks or access your bookmarks using the iGoogle
Bookmarks gadget.

74. Did you know you can search within your returned results? Scroll
down to the bottom of the search results page to find the link.

75. Search locally by appending your postcode to the end of query. For
example Indian food BA1 2BW finds restaurants in Bath, with addresses
and phone numbers!

76. Looking for a map? Just add map to the end of your query, like
this: Leeds map

77. Google finds images just as easily and lists them at the top, when
you add image to the end of your search.

78. Google Image Search recognises faces... add &imgtype=face to the

blocks of text you can type or cut and paste.

89. There's also a box that you can enter a direct URL into,
translating to the chosen language.

101个Google技巧zz

有的只是个joke……
Happy 10th birthday to Google~

1. 更加全面地用Google搜索的最好方式是点击高级搜索。
2. 它可以让你搜索更加精准的词组,"所有词组"或者是适当的搜索框里输入词组的某一个特定关键词。
3. 在高级搜索里你依然可以自定义在一张页面上展示多少个搜索结果,你所寻找的信息语言和文件格式。
4. "搜索以下网站或网域"可以让你通过输入一个顶级域名(如.co.uk)来限定搜索结果。
5. 你也可以点击"日期、使用权限、数字范围和更多"的链接以获取更高级的功能。(Google中文直接分条在页面展示。)
6. 保存设置,这些高级功能大多也可以在Google首页的搜索框中通过命令行参数来实现
7. Google的主要搜索可以无形地用布尔结构"AND"来结合。你当输入smoke fire - 它表示寻找smoke AND fire.
8. 要让Google搜索Smoke 或者fire,只需要输入smoke OR fire.
9. 你也可以用 | 来代替OR。如:smoke | fire.
10. 像AND 和 OR 这样的布尔结构对大小写非常敏感。他们必须是全部大写。
11. 搜索专有名词,然后输入用括号括住的一个或者几个关键词。比如water (smoke OR fire)
12. 寻找短语,可以把它们放在引号里。比如:"there's no smoke without fire"。
13. 同义搜索来寻找那些类似的信息,只须在你的关键词臆加一根波浪线,比如:~eggplant.
14. 用减号来排除关键词,如:new pram -ebay 可以让搜索结果排除来自Ebay的婴儿车信息。
15. 像 I, and, then ,if 这类普通词语是要被Google 忽略的。他们被称作停滞词语。
16. 而加号却可以让这些停滞词语给包含进来,比如:fish +and chips.
17. 如果一个停滞词语被包含在那些作为短语的引用标记中间的句子中时,这些词语是被Google允许的。
18. 你也可以要求Google进行简省搜索,试一下:Christopher Columbus discovered *
19. 用数字范围功能来搜索数字范围。例如:搜索价位在300英到500英磅之间的索尼电视可以用以下字串:Sony TV £300..£500。
20. 通过高级搜索Google认可13种主要文件格式,其中包括Office, Lotus, PostScript, Shockwave
Flash 和text。
21. 搜索这些文件只需直接使用修饰符 filetype:[文件扩展名]。例如:soccer filetype:pdf.
22. 要排除整个文件格式,只需使用以前我们排除关键词时使用的相同布尔句法:橄榄球 -filetype:doc
23. 事实上,只要你的语法正确,你可以混合使用任何布尔搜索运算符。举个例子便是:"sausage and mash" -onions
filetype:doc
24. Google也有很多功能强大却隐藏着的搜索参数,例如"intitle"
仅仅只会搜索网页标题(titles).你可以用这个例子试一试:intitle:网页设计
25. 如果你只是寻找文件而不是网页,只需用index of 代替intitle:参数。它可以帮助你寻找网络和FTP目录。
26. inurl这个修饰语只会搜索网页的网址,不妨用这个例子试一试 inurl:spices
27. 通过 inurl:vien/view.shtml 你可以找到在线的网络摄像头。
28. inanchor这个修饰语非常特别,它仅仅只会寻找那些作为超链接的文本。
29. 想知道有多少链接指向一个网站。可以试试这个语法:link:网址 - 比如link:www.mozilla.org
30. 同样的,你也可以通过 related:修饰语来找到Google认为相似的内容。比如: related:www.microsoft.com
31. info:site_name 这个修饰语可以返回关于某特定页面的信息。
32. 同样的,在普通搜索后点击"相似网页"可以链接到Google认为相似的页面结果。
33. 如果只想搜索某一个风址里的内容,可能用site: 来实现,比如说search tips site:www.techradar.com.
34. 上述技巧通过像www.dmoz.org这样的目录网站并动态地生成网址。
35. 也可直接进入Google Directory这样的人工挑选出来的数量有限的数据库网站,网址是www.direcory.google.com
36. intitle和inurl这样的布尔运算符像OR一样在Google Directory中同样适用。
37. 当你用Google图片搜索时,用site:的修饰语可以只搜索某一个网站内的图片,比如 dvd recorder
site:www.amazon.co.uk
38. 同样的,用"site:.com"只会返回带有.com域名后缀网站里的结果。
39. Google新闻(news.google.com)有他自己的布尔运算符。例如"intext" 只会从一条新闻的主体内容里查询结果。
40. 在Google新闻里如果你用"source:"这个运算符,你可以得到特定的新闻存档。比如:heather mills
source:daily_mail
41. 通过"location:"过滤器你可以等到特定国家的新闻,比如 location:uk
42. 同样的Google博客搜索(blogsearch.google.com)也有它自己的句法。你可以搜索某篇日志的标题,比如
"inblogtitle:<keword>"
43. Google的普通搜索也可以确实也可以得到精确的结果,不如用"movie:<name of film>" 来寻找电影评论。
44. "film:"修饰语效果也一样。
45. 在搜索框里输入上映时间,Google会提示你提交你的邮编,然后Google就会告诉你什么时候什么地方将会有好戏上演。
46. 如果想要一个专门的电影搜索页面,可以去www.google.co.uk/movies
47. 如果你圈选了"记住地点"后,下次你查询电影放映时间只需要输入电影名字就够了。
48. Google确实在电影方面的搜索上下了些功夫。比如在搜索框中输入"director:<电影名>"你将得到什么结果?你肯定猜到了吧。
49. 如果想得到演员名单,如需输入"cast:name_of_film"
50. 在乐队名、歌曲名或者专辑名前加上"music:"可以得到相关的音乐信息和评论。
51. 如果你在搜索框里输入"weather London"便可以得到伦敦最近四天完整的天气预报。
52. Google也内置了词典,在搜索框里用"define:the_word"试试。
53. Goolge保存了网站过去的内容。你可以直接搜索某个页面在Google服务器里的缓存,相关句法是"keyword cache:site_url"
54. 相应的,直接在搜索框里输入"cache:site_url"可以直接进入缓存页面。
55. 如果你手边没有计算器,只要记住Google同样内置了这么一个功能。输入"12*15"然后点击搜索试试。
56. Google的内置计算器不但可以转换尺寸还可以理解自然语言。搜索一下"14 stones in kilos"
57. 汇率转换也同样适用,试试"200 pounds in euros"
58. 如果你知道某货币的代码,将得到更加可靠的结果,例如"200 GBR in EUR"
59. 温度呢?Google也没有放过,输入"98 f to c"便可以把华氏转换为摄氏。
60. 想知道Google到底有多聪明呢?输入"2476 in roman numerals"然后点击"搜索"就知道了。
61. 你也可以保存你的Google使用习惯偏好,只需要在www.google.com/account上注册一个帐号便可。
62. 一旦有了Google帐号,不旦可以免费获得一个Gmail帐号,最主要的是可以畅通无阻地遨游于Google的世界。
63. 登陆你的Google帐户,通过"iGoogle"你还可以个性化你的Google主页。
64. 在"iGoogle"上点击"Add a Tab"来添加多个内容模块,Google会根据你添加的甩有模块来自适应整个页面。
65. "iGoogle"允许你为主页更换模板,点击"Select Theme"便可改变现有的默认主题。
66. 有一些"iGoogle"主题会随着时间的改变而改变,比如"Sweet Dreams"就是一个随着白天到夜晚的更迭而改变的一款主题。
67. 点击"Try something new" 下面的"More" 就可以看到一个更加完整的Google网站列表和一些新的功能。
68. "Custom Search"帮助你为你自己的网站建立一个Google牌的搜索引擎。
69. 另外,那张列表还忘掉了一个很有用的服务"Personalised
Search",不过你可以通过访问www.google.com/psearch来使用它。(一个保存你搜索记录的服务——译者注)
70. 这个页面列出了你最近的搜索,并按特定分类来区分他们,点击"pause" 就可以阻止Google记录你的搜索历史。
71. 点击"Trends"可以看到你最访问的网站,你最搜索最多的条目以及最常点击的链接。
72. 个性化搜索同样包括了一个书签服务,它帮助你在线保存书签并可以在任何地方获取他们。
73. 更方便的是,你可以在"iGoogle"上添加一个书签模块来添加或访问它们。
74. 你知道你还可以搜索Google返回的结果么?滑到搜索结果页面底部便可以找到那链接。
75. 在你的查询后面附加你的邮编便可以搜索本地信息。
76. 找地图?只需要在搜索关键词后面多写一个"map",比如"Leeds map"
77. Google搜索图片(这里指直接在Google首页而不是Google
Map页面,译者注)非常简单,只要你在关键词后而多写个"image",你就会在搜索结果的顶部看到相关的图片结果。
78. 神奇的是Google图片搜索可以识别人脸,在浏览器地址栏搜索结果页面网址后面添加"&imgtype=face"
确定后Google会过滤掉所有不是人的图片。
79. 想关注股市行情?只需要在"stock:"后面填上公司的股票代码便可以得到从Google财经返回的结果。
