<p>If you go its wetsite http://thinkgos.com/, you will see it talks lots of cloud. It&#8217;s interesting, but it is not the reson i chose it. Ubuntu 8.04 is inside gOS. So, it time to learn a new linux system. I neve use a Derbin based system, I&#8217;m not sure it could run for me how long.</p>

			<content:encoded><![CDATA[<p>Peoples always love whatever Google&#8217;s invention, I am using Gmail and GTalk every day too. But I think I couldn&#8217;t say I like google anytime. That&#8217;s just because Chrome. It was installed on my laptop yesterday. I&#8217;m trying it out when I access any of my google services (Gmail, Reader, Doc, etc&#8230;). There are some App shortcuts are already on my XP deskdtop.  Base on one day experience of Chrome, I&#8217;d like to talk about reasons I don&#8217;t like Chrome. I has not tested it too much at present, just few comments below:</p>
<p><img class="alignnone" src="http://blogs.zdnet.com/perlow/images/chrome-constrictor.jpg" alt="" width="412" height="274" /></p>
<p><span id="more-49227"></span><strong>Chrome&#8217;s Name:</strong> I still do not figure out how to pronounce this word, someone says it sounds like a man perfume; I do thinks so. But it&#8217;s ok for a name of software, I don&#8217;t care about too much what it called.  FireFox is cool name, everyone know it.</p>
<p><strong>Crash <span style="font-size: 14px">Continually</span></strong>: It proved Chrome browser is on early stage. For me, I won&#8217;t any software on my laptop send out any piece of information which I don&#8217;t know or couldn&#8217;t understand. So, I will never  turn on crash report option for any software. It is still crashing frequently, I might will not use it any more; or install it.</p>
<p><strong>Bookmark on top: </strong>My laptop has supper wide screen, so all of bookmarks are listing on the left side of Firefox/IE. I like to access bookmark from left side of screen. It is on the top and just below the address bar, I have to close it.</p>
<p><strong>ADs in Gmail/anywhere it could be:</strong> In Firefox, I get really few AD showed up. Nobody love ADs, but Google can not do with our AD.</p>
<p><strong>Without Add-ons:</strong> It is so important for extending the usage of your browser. Add-on makes a browser to do more jobs as you wash for. I can list some add-ons of Firefox, they are very helpful and I must have all of them.</p>
<p>I thinks Google really good at marketing. it crashed into browser marketing, its ambition knows no limits. All in all, Chrome is not a good enough to be my default browser; Fixfox will keeping do this job for me. Chrome is a ok software, it is no offence to Googl&#8217;s fans.</p>

I think it is worth to do, since more and more peoples are surfing from mobile device. You might get a wap link on your home page, I will do it after get this post publish out.</p>
<p><img class="alignnone" src="http://www.yunnanshouji.com/Shop/UploadPhotos/200804/940699_cxl070110apple_iphone_03.jpg" alt="" width="145" height="203" /><img class="alignnone" src="http://www.phonesreview.co.uk/wp-content/phoneimages/2007/08/blackberry-8820_02.jpg" alt="" width="190" height="202" /></p>
<p>Now, it time to explain how to do a wap blog.</p>
<ol>
<li>open <a href="http://www.google.com/gwt/n" target="_blank">Google Moblizer</a> in your browser</li>
<li>enter your url of your blog, then click go button</li>
<li>google moblizer will adjust your blog page to flat wap version.  only one font and same size, smaller pictures, white background; those are perfect to fit for more cell phones. it is also easy to read.</li>
<li>copy the current url into a text file, this url looks like &#8216;http://www.google.com/gwt/n?u=http%3A%2F%2Fwww.martinliu.cn&#8217;</li>
<li>go to <a href="http://www.tinyurl.com" target="_blank">www.tinyurl.com</a>; paste the url to make a tinyurl</li>
<li>finally, you get a tiny url for your wap version blog</li>
<li>enjoy :)</li>
</ol>
<p>I&#8217;m using wordpress for my blog. WordPress should have some sort of plugin to do this. If you know about it, please leve me a comment. Thanks!</p>

<p>If you have no idea, you should read this post &#8220;<a href="http://news.cnet.com/8301-10784_3-9955184-7.html?tag=blog.1" target="_blank">Google spotlights data center inner workings</a>&#8220;.</p>
<p>There are some notes I took as blowing.</p>
<p>Google Infrastructure:</p>
<ul>
<li>clusters of 1,800 servers are pretty routine.</li>
<li><a title="We're all guinea pigs in Google's search experiment -- Thursday, May 29, 2008" href="http://news.cnet.com/8301-10784_3-9954972-7.html">an ordinary Google search query that involves 700 to 1,000 servers</a></li>
<li>puts 40 servers in each rack</li>
<li><a title="Use Google Maps to find Google data centers -- Friday, Apr 11, 2008" href="http://news.cnet.com/8301-10784_3-9917205-7.html">Google has 36 data centers across the globe</a>; Google has more than 200,000 servers; growing every day.</li>
<li>Google largely builds its own technology.</li>
<li>to treat each machine as expendable; Google prefers to invest its money in fault-tolerant software. NOT hardware  fault-tolerant.</li>
<li>Google uses ordinary hardware components for its servers, it doesn&#8217;t use conventional packaging. Google required Intel to create custom circuit boards.</li>
<li> As to the servers themselves, Google likes multicore chips, those with many processing engines on each slice of silicon.</li>
<li>three core elements of Google&#8217;s software: <a class="external-link" href="http://labs.google.com/papers/gfs.html">GFS, the Google File System</a>, <a class="external-link" href="http://labs.google.com/papers/bigtable.html">BigTable</a>, and the <a class="external-link" href="http://labs.google.com/papers/mapreduce.html">MapReduce</a> algorithm.</li>
<li>Google helps with<span style="color: #ff0000"><strong> a lot of open-source software projects</strong></span> that helped the company get its start, these packages remain proprietary except in general terms.</li>
<li>GFS stores each chunk of data, typically 64MB in size, on at least three machines called chunkservers; master servers are responsible for backing up data to a new area if a chunkserver failure occurs.</li>
<li>The largest BigTable instance manages about 6 petabytes of data spread across thousands of machines.</li>
<li>On any given day, Google runs about 100,000 MapReduce jobs; each occupies about 400 servers and takes about 5 to 10 minutes to finish.</li>
</ul>
<p><strong>总结一下上面的东西：</strong></p>
<p>Google不是买的成品服务器，而是去Intel定制的芯片自己攒的，特别喜欢使用多核的cpu，由于他们的程序都适应与多线程并行计算的方式。一个群集有1800个服务器是非常平常的。Google大概有二十万个服务器，每40个放在一个机架上，分布在全球36个数据中心。Google不使用商业的服务器包括数据库等软件，一来造价太高，二来无法满足扩展性的需求。Google使用了很多的开源软件项目，事实上它们就是站在开源软件的肩膀上发家的；GFS，BitTable等都是它们常用的。广泛使用软件容错技术。</p>
<p><strong>传统商业公司和google的不同：</strong></p>
<ol>
<li>从硬件到软件基本都使用现成的商业产品。基础架构中的每个环境都是钱堆出来的。用钱来节省时间，不过google的时间和金钱的节省都是值得学习的。</li>
<li>在容错技术上硬件HA技术用的最多，群集中的服务器数量不多。</li>
<li>不同业务系统之间几乎是孤立的。从数据库到web到关联的网络设备都是一套独立的系统，甚至于按业务系统划分运维的团队。</li>
<li>系统的扩展性比较小，对核心部件：如核心应用服务器或者核心数据库服务器的扩展，垂直扩展比较多，追求单机的多CPU，高主频，高内存。而另一方面：在这些系统上的压力测试和性能调优工作异常的痛苦。</li>
<li>饱受被商业软件公司绑定之苦，如果数据库、应用服务器等出了产品的bug，厂商提供fix一般都需要一定的时间周期-时间代价比较高，原厂的现场技术支持服务金钱代价也比较贵。</li>
<li>从高层看：CTO、CIO、CEO没有正视开源技术。只要预算允许，引入和采购业内流行的商业技术似乎是永恒的明智之举。开源软件技术应用的有不过很少。</li>
<li>从基层看：工程师可能有足够的某项开源的技能，不过没有适当的渠道能反应到上层来提议使用该技术；如果在下面擅自使用了某种技术，非常担心出了IT事故后对后果的承担。开源技术对技术人员只是一个爱好而无法应用与自己的日常工作中。</li>
<li>特别是中国用户对最新潮的IT技术永远保持着极度的热情，不管是硬件和软件买就买最先进的，数据中心的机房最后成为博物馆，新老系统很难整合资源。把基础架构的彻底改变寄希望于未来的某种技术革命，实际上技术变革已经悄悄发生了好几波了，怎么管理现状怎么就是越来越艰难，越来越花钱呢？走中国特色道路真的值得提倡一下了。</li>
</ol>
<p>Google的这些特点真是引人入胜，任何企业都无法复制；而且也不可能复制，它毕竟是一个商业公司而不是一个开源项目。如何使用现有的技术和人员来打造出你自己的完美基础架构呢？现实中这么多的role model已经证实了很多技术都是可用的，完美的境地也不是空中楼阁。如何集思广益并多多引入开源技术和人才可能是一个需要斟酌的题目。</p>

<p>I read a post last night, <a href="http://googleblog.blogspot.com/2008/04/developers-start-your-engines.html">Developers, start your engines </a>Even I am not a developer, I definitely look forward to sing up <a href="http://appengine.google.com/">appengine. </a>. But I can not have it, that&#8217;s pity. Let&#8217;s see how to create a &#8216;hello world&#8217; appp on google appengine.</p>
<p><object width="425" height="355"><param name="wmode" value="transparent" /><param name="src" value="http://www.youtube.com/v/bfgO-LXGpTM&amp;hl=en" /><embed type="application/x-shockwave-flash" width="425" height="355" src="http://www.youtube.com/v/bfgO-LXGpTM&amp;hl=en" wmode="transparent"></embed></object></p>
<p>Let me see your app on google. See more on <a href="http://appgallery.appspot.com/" target="_self">http://appgallery.appspot.com/</a></p>
<p>Google App Engine是一个开放的应用运行平台，它提供给你的应用无限的扩展性，并免费的在后台运行。记得以前和同事曾经有过一个话题“GOOGLE的基础架构是怎么搭建的？”，google的成功和它对基础架构资源的结构方式是密不可分的，大家都想知道这个秘密。不过现在好像你不需要模仿并拥有一个相同或者相似的了，你有可能免费访问并使用了。Google把它定义为一种服务，和邮件服务好像没有任何区别。IT基础架构实现和提供的是计算资源，而以后随着‘云计算’等技术的实现，使用这种资源可能会想使用电一样方便。不需要拥有发电厂，你的电灯依然会亮。</p>
