google几星期前,一个朋友接受了Google公司的面试,他透露了面试中的一些问题。顺便,我把从其他几个曾经面试过的人那里听来的内容也整理在一起。最大的互联网公司Google的一份面试题集,看看你是否能够回答出来。

  • 1、一辆学校班车里面能装多少个高尔夫球?
  • 2、你被缩小到只有硬币厚度那么点高(不是压扁,是按比例缩小),然后被扔到一个空的玻璃搅拌器中,搅拌刀片一分钟后就开始转动。你怎么办?
  • 3、要是让你清洗整个西雅图的所有窗子,你会收取多少费用?
  • 4、怎么才能识别出电脑的内存堆栈是向上溢出还是向下溢出?

  发现最近很奇怪,老是接到未知来电,全是只想一声的…大家有没有遇到这种情况?
   我在网上查了手机号码归属地,来自全国各地的都有,什么河南新乡、广西南宁、广东东莞、山东济南,广东深圳……
   每次都只响一声,烦死了~~
   我猜想有几种可能:
   1、手机忘锁键盘了,放在包里不小心按到我的号码。
   2、打错了。
   3、有人恶作剧。
   3、一些骗人的公司专打这种电话骗钱的。
   分析一下,手机忘锁键盘,按到我的号码,11位,也太巧合了吧?这种机率极小……打错了的时候一般不
晓得自己打错,通了电话听了声音才知道是打错的吧?这种可能也可以排除了。第三种可能,有人恶作剧,
这种想法的起因是其中一个号码打了几次,每次只响一声,但是看到来自不同地方的号码那么多,我又觉得
不太可能了~~~原先听说有些“公司”,专打这种电话,只想一声,有些人看到是未接来电就回打,于是手
机的话费突然暴涨……不知道我的猜想对不对?只是老接到这样的电话真的很烦呀~~你们有没有这种烦恼呢?

接下来,继续……
generic viagra usa在你的网站根目录下,插入robots.txt.
为什么要这么做?robots.txt如何在网站的SEO中起到作用呢?简单的说就是,搜索引擎会根据robots.txt的内容“按规操作”。哪些内容应该搜索,哪些内容不应该搜索,全部都由robots.txt来指挥. 可以点击“”查看相关设置,将它复制到robots.txt再放在你的wordpress 根目录下就可以了。
TIPS:请注意下面的一句:

# disallow all files with ? in url
Disallow: /*?*

上面的那句是让搜索引擎不去搜索所有带“?”的网址。如果你的WordPress的链接形式是默认的那一种:yourweb.com/?pxx的形式的话,请把它删掉。
这样,搜索引擎在搜索我们的网站时才会显得更有效率,避免了浪费时间什么的去搜索一些无意义的目录,如是wp-admin/这一类目录。我们也能通过robots.txt更好的让自己的网站被收录。所以,如果你的WordPress还没有robots.txt,赶快设置一个吧!

正如题目所说的,一步一步学习seo. 我的blog没有进行过任何搜索引擎优化,下面我就决定以我的blog来做做实验咯!
SEO(Search Engine Optimization)就是搜索引擎优化。如何让类似与google、baidu等搜索引擎更好的搜索到你的日志呢?且听听大师们怎么说……
1、尽量使用两栏式的布局(模板)。虽然现在我们可以很轻松的找到很多漂亮的模板,两栏、三栏、甚至还有四栏的。但是,对于搜索引擎的优化,我们最好还是采用两栏的布局。因为爬虫是从左到右、从上到下来抓取你网站的内容的。如果你的左侧刚好有几个侧栏,那么爬虫会先抓取拟的链接,RSS等的东西,而且它抓取的字数是有限的,刚好抓完了还没有抓到你网站的主要内容怎么办?
2、说到爬虫抓取的内容是有限的,那么我们如何解决呢?最好是把你网站的主要内容置于前面。
3、只装一个Tag插件,避免复杂。
4、尽量让搜索网站慢慢获取你的网站内容,避免使用什么MET TAG之类的插件,自然一点好,不是吗?
5、侧栏的h2和h3标题最好加粗显示。
6、日志的标题h1也最好显示为粗体,并且简单的添加一些与你的网站内容相关的关键词。
怎么样?是不是很简单?其实看了上面的内容,你仅仅可以对自己的网站的模板进行一些简单处理以达到SEO的目的。但首先我们得知道应该如何做?或者说应该针对哪些方法进行优化和调试。那么SEO的重点在哪里呢?

由于在论坛里听说他觉得opera的结构和样式写得很好,想学习学习,于是我就打开的官网上开始小小的代码”剖析”了一番。

        首先,opera的界面设计得很简洁,感觉很清新、爽朗。不得不赞一下它的UI设计师…..

        其次,在Fire Fox中打开页面,用web developer工具查看image信息。发现网站切的图都是好大的…甚至可以循环显示的也切成高300px的图片。我在想这样不是增加文件的大小么?

        然后,用fire bug工具查看html、css等。看到css 里面有一种很特别的写法,#side p +h2 {margin:10px;} 这样的选择器我还没有见过,不知道什么意思以及起着什么作用。后来查看了css手册,以及查阅了一些资料,才算清楚怎么回事了。举个例子:

CODE:

<div>
<h1>对选择器的思考</h1>
<p>这是一个段落p的内容!<strong>这里是strong的内容</strong>这是一个段落p的内容!</p>
</div>

从上面我们可以看出h1 和 p 两者的关系是相邻的。

那么我们定义的样式如果是

 h2 + * { color:#000;}/*所有紧随 h2 的元素内的文字都将呈现黑色*/

同理我们可以理解,#side p +h2 {color:red;} 的含义,就是紧随着被#side包含的p元素内的文字都将呈现 红色。

有一次在木屋烧烤吃烤鱼时, 给我出了道面试题,题目就是“清除浮动有几种方法?”当时我心里一愣,平时我们用的最多方法的就是在需要清除浮动的标签上添加一个属性”clear:both”,难道还有第二种方法?我回答了两种方法,一种是直接在html文件中写<div style=”clear:both;”></div>; 还有一种就是在html文件中写<div class=”clr”></div>,在样式表里面添加”.clr{clear:both}” 回答完了,鬼摇摇头说,你说的其实只是一种方法…. 其实还有一种方法更简单,只要为需要清浮动的标签加上overflow这个属性. 有点扯远了,还是回到正题,下面就把鬼的方法透露给大家吧……

        坐在上海飞往深圳的飞机的时候,我的同事就告诉我,上海和深圳是两个感觉完全不同的城市。深圳给人感觉会很新。坐了四个小时的飞机,终于到了深圳` `真不晓得怎么会坐那么久…我记得以前从海口坐到北京也才三个多小时…
       到了深圳,我收到王莉的短信,说:”深圳真欢迎你,打雷下大雨来迎接你们的到来~~  ”这话怎么听起来怪怪的?…
       打的到了公司安排的宾馆,洗了个热水澡,就美美的睡了一觉。第二天不用上班,我们都睡到了九点多…说实话,我门已经有差不多两个星期没有正常上班了…谁叫公司折腾人,搬来搬去呢?
        坐在深圳的公交上,沿途看着深圳(南山区)的风景。嗯….比张江热闹多了。经过科技园,好多有名的公司都在那,什么方大、联想、创维、华为、中兴……好有氛围!在深圳,很少看到很古老的房子,到处都是新的。果然和我同事告诉我的一样…….对深圳的第一印象不错,嗯嗯…….

昨晚翻来覆去怎么也睡不着,索性一大早就跑来公司。一路上,我的脚步变得越来越沉重…… 
        也许,我没有来过上海,我会爱上深圳。 
        也许…… 
        变化太快,没有给我一个反应的时间。 
        昨天我还特地从南昌带了煌上煌兴致勃勃的赶着中午的时间给他们吃。大伙还没有顾得上吃,就告诉了我一个很不幸的消息。公司搬回深圳,只留下少部分人一起回深圳,其它的就意味着失业。当时给我选择回深圳还是留在上海待业。我懵了……下午就要给答复,我不知道该如何选择。天意弄人!我脑海里有很多疑问,只有一个名额。为什么是我选择?为什么不留下经验丰富的同事?从对重构一无所知到从事这一行,他们都是我的启蒙老师,教了我很多很多,包括技术,包括思想。 
        我们UI组还有两个姐姐。李旭姐和海燕姐分别是我们的UI经理和设计师。我们经常一起出去聚餐、一起包场打羽毛球、一起去酒吧、一起吃中餐,一起开玩笑……今天到了公司,冷冷清清的。心里有种酸酸的感觉…… 
   在上海待了三个月,我们有很好的打算。可是去深圳,还没有什么准备。到了那边就要一个人去找房子了……每天一个人上班一个人回家。原先公司里熟悉的面孔没了,实在不敢想象……更难办的是, 去了深圳,我们都不知道未来会变成怎样……… 
       有些人劝我,这是个机会。总监让我留下,那么我就得好好的把握机会。也许去了深圳,我能得到更好的发展。可是,我应该去那边尝试么?我还有时间么?我是不是太自私了? 
   烦、乱、糟,就是我现在的心情了。

对… 只有90秒,告诉你什么是Web 2.0,等你点进来看到这篇文章的标题,已经花了你10秒了,我还剩80秒

1.Web 2.0是概念不是产品,也不是指什么新技术:
Web 2.0是O’Relly(欧莱礼,以每本书都有一支动物当吉祥物出名)的创办人Tim O’Relly提出的。
原版英文网页:
简体中文翻译:
Web 2.0是相对于1.0(之前的叫1.0)而说的,没有1.5、1.9、3.0这类的说法,都是其它营销人自己创的说法。

2.Web 2.0的7大重点特色:
a.以网站为平台(The Web As Platform)
b.利用集体智慧(Harnessing Collective Intelligence)
c.资料才是下一代的Intel Inside(Data is the Next Intel Inside)
d.终结软件发布周期(End of the Software Release Cycle)
e.轻量化的程序开发模式(Lightweight Programming Models)
f.软件超越单一设备(Software Above the Level of a Single Device)
g.丰富的使用者体验(Rich User Experiences)

3.几个重要的事实:
1.Google从来没说自己的服务叫Web 2.0,他们觉得这只是个广泛的观念,代表这一世代的网站服务是重视社群精神的。

2.BBS其实完全符合Web 2.0概念,只是没有厂商愿意承认。尤其是以广告营销为主的炒作厂商。

3.一般大型网站公司对自己员工的声音都不重视了,更何况来自外面的网友的声音?搞个炫炫的Ajax讨论版、留言版或意见回复,就叫Web 2.0?先搞好员工福利再说吧…(此为某大型网站公司最近传闻大量在年终裁员,为这些员工报不平)

90秒到了,你了解了Web 2.0吗?可以拿去骗不懂的客户了…^^”

       已经工作快一个月了,不过还是很盼望发薪水的那天,毕竟,那是我人生中的第一笔薪水。意义很重大哦!
       公司坐落在上海张江一个很不起眼的位置,大概对于网络公司来说,地理位置的要求不高吧,不一定要在繁华的闹市区。每天上班打卡,偶尔忘了打卡就亏咯,有一天我加班到晚上8点,竟然忘记打卡T.T
       每天早上9点上班,我一般都在8点半就到了公司,然后吃早餐,开始一天的工作。整个公司就我们重构组的位置比较醒目,一人有两台显示器,一台LCD的,一台是CRT的。有些外行的同事还以为我们每人用两台电脑呢~~~汗!电脑的性能不错,双核还有1G内存,反正是比我家里那台老牛走得快多了…
        刚来时我的主管兼导师告诉我,每天必开的程序:1、BQQ(作为我们公司内部的即时交流工具)2、邮箱。每天的公司内部信息和通知都会发送到邮箱。不能不看。3、做好的页面上传到SVN,版本控制上面,方便其它同事的提取。4、每天中午准时有封邮件,主题:茶余饭后。让我们了解一些行业内的动态及天气预报、娱乐信息等。

buy propecia online Several key problems still need to be addressed. For instance, it would be of great benefit to determine the structure of several PDE holoenzymes to fully understand their mechanisms of regulation. Therefore, substantial effort is being expended in this area. A concept gaining great support is the idea that different PDEs subserve different pools of cAMP and cGMP in the cell. We are only just beginning to be able to measure PDE activity in subcellular compartments of the cell in real time. This is an area that clearly needs to be developed, including identification of molecular mechanisms that provide and control PDE subcellular localization. We also need to identify good animal models that accurately reflect the regulation and roles of PDEs in human tissues as many examples now are available for different modes of regulation between mice and men. At a minimum, putative regulatory schemes identified from studies in mouse, Drosophila, or zebrafish need to be tested quickly in human tissues. If unsuccessful, interferes with other treatments Do you have more than one sexual partner? Sildenafil (Viagra), whose labeling was approved by the U.S. Food and Drug Administration (FDA) in March 1998, is the first oral medication to be marketed for the treatment of erectile dysfunction. Sildenafil inhibits the conversion of cGMP to guanosine monophosphate in the corpus cavernosum, thereby increasing the available concentration of cGMP. This reaction is largely catalyzed by the enzyme phosphodiesterase type 5. Sildenafil inhibits this enzyme, resulting in relaxation of the cavernosal smooth muscle.17 Sildenafil is absorbed rapidly, with peak plasma levels achieved within an hour. It undergoes hepatic metabolism and has a half-life of about four hours. Missed Signals continued... There are most queries on the impact of alcohol consumption on sexual comfort and also the potential of the drink to get involved with libido and climax scenarios. Hormone therapy can raise low testosterone levels, which may improve both erections and sex drive. McCullough adds, "If you put it in the context of a physical problem and not a sexual one, most men will be less likely to 'shut down' or shut you out." While some men would rather go the treatment route alone, others might welcome the support of their partner, so be certain to make the offer to go with him, and then let your man decide. In older men, ED usually has a physical cause, such as disease, injury, or side effects of drugs. Any disorder that causes injury to the nerves or impairs blood flow in the penis has the potential to cause ED. Incidence increases with age: About 5 percent of 40-year-old men and between 15 and 25 percent of 65-year-old men experience ED. But it is not an inevitable part of aging. When the sufferer is aged the problem is generally physical in nature. Physical causes of Erectile Dysfunction include damage to penis caused by an injury, blockage of arteries and veins in the penile area, consequence of diabetes or drug and alcohol overdose or old age for that matter. No matter what the cause is ED pills like Viagra, cialis and levitra are very potent in over coming sexual dysfunction of Erectile Dysfunction in males of any age. So zero in on to ED pills to enable yourself to overcome your erectile dysfunction problem. viagra for sale online There are many treatment options today. These include medicines taken by mouth, injections into the penis, medicines inserted into the urethra (urinary channel), vacuum devices, and surgery. In order to treat erectile dysfunction effectively, you must be aware of and comfortable with the possible side effects and complications that may occur with each therapy. Adult 25-100 mg PO 1 h before sexual activity; best absorbed when taken on empty stomach What are the specifics of the circumstances under which ED first occurred? Erectile Dysfunction: A Harbinger of Heart Trouble "Regular intercourse has an important role in preserving erectile function among elderly men, whereas morning erection does not exert a similar effect," Koskimki said in a statement. "Continued sexual activity decreases the incidence of erectile dysfunction in direct proportion to coital frequency." If you are scheduled for surgery, including dental surgery. A Little Padding Helps, Too Nerve or spinal cord damage: Damage to the spinal cord and nerves in the pelvis can cause erectile dysfunction. Nerve damage can be due to disease, trauma, or surgical procedures. Examples include injury to the spinal cord from automobile accidents, injury to the pelvic nerves from prostate surgery, multiple sclerosis (a neurological disease with the potential to cause widespread damage to nerves), and long-term diabetes mellitus. Figure 4. PDE5 inhibition increases intratumoral T cell infiltration and activation of tumor-specific CD8+ T cells. (A) BALB/c mice were challenged with CT26WT cells s.c. on day 0, and 20 mg/kg/d sildenafil was added to the drinking water where indicated. The mice were killed 15 d later, and the tumors were stained with hematoxylin-eosin. (BD) BALB/c mice were challenged with C26GM on day 0. They were treated with sildenafil, received 20 x 106 C26GM vaccine-primed splenocytes from H2d pIL-2/GFP mice, or were given both treatments as indicated. (B) The tumors were surgically removed 9 d later, and the CD8+ T cell infiltrate was determined by flow cytometry. The percentage of CD8+ T cells was plotted against the tumor size at the time of tumor harvest. The software-provided tool (Sigma plot) was used to fit a three-parameter exponential decay curve (y = 36.13 + 92xe5.93x). Pearson bivariate correlation, P = 0.0000002. Data are derived from three independent experiments, with each containing five mice per group. (C) Intratumoral single cell suspensions were labeled with anti-CD25 or -CD69 antibodies.
