我家里还放着3台F5的高性能4层交换机。这都是当年为了对付DDOS攻击购买的设备，每台都要N万美元哪！

现在换了更好的型号了，淘汰了，咳.....

自己临时用还好了，只能当作文件存储空间。
如果能够当文件服务器就好了，这样可以放图片和MP3或者视频，然后到别的地方发链接。

你的无线MODEM是不是有几个网线口的那种？因为一般是会有的。那么，就直接把只有有线网卡的那台机器通过一条网线连接无线MODEM。然后在MODEM上设置拨号即可。

如果不会在MODEM上设置拨号，或者没有这个功能，那就在随便一台电脑上拨号，拨号的电脑设置为internet共享即可。

具体的设置google搜索一下“internet共享”即可。

google reader是我目前每天都要使用的阅读工具，使用相当方便。一直盼望不断增加新功能。

可是这个翻译功能我局不知道有什么作用了，但不懂得东西，自然也不会去订阅了。

Google实用功能集锦

驱动之家[原创]   作者：大川  编辑：Zzyq　2008-10-14 15:16:05 4295 人阅读    [投递]

Google仿佛永远都有用不完的新点子，幸运的是，它永远都有足够的美刀和技术天才来实现这些新鲜玩意。如果现在还有人认为Google只是搜索引擎，那实在是太孤陋寡闻了。Google的创新能力强大到什么程度？你总是有不知道的新玩意——Google的新产品开发速度居然比绝大多数用户学习和习惯的速度还要快，“你用得没有他开发得快”。数也数不清的日常应用，吃喝拉撒衣食住行简直无所不包。大家最常用的Gmail, GoogleNews这些就不再介绍了，本文介绍一些很实用的、你可能不知道的功能。（注：由于Google产品开发总是基于美国人的习惯，有部分功能尚未完全本地化，可能对中国用户不适用。） 1.图书搜索 Google Book Search可以检索到绝大多数没有版权保护的整本的文学著作。想看英文原版的简奥斯汀“理智与情感”吗？搜索“Senseand Sensibility”http://books.google.com/books?id=RtT0OLKFMHsC&printsec=frontcover&dq=Sense+and+Sensibility&ei=yQX0SKrDD5rIM8TeteMI可以立刻找到,你甚至可以下载8.1M的完整版PDF. 再来试试“红楼梦”,你不会失望的。http://books.google.com/books?id=e1NgBK4k2cwC&printsec=frontcover&dq=红楼梦&ei=HgT0SNqECJOqMqWM9cAL&sig=ACfU3U2euA0hZnDfaIVocSvfq34V15My5w#PPP1,M1 2.世界时间查询 想知道纽约现在几点？去Google搜索：time new york 你可以在"time"后面加上任何你想查询的城市或国家名称。 3.货币转换 79英镑折合多少人民币？去Google搜索：£79 in chinese currency, 或者79 GBP in CNY, Google告诉你答案。类似地, 8000 jpy in usd 可查询8000日元折合多少美元。 4.发现有趣的地方 Google Earth, 想看哪里就看哪里。Google最新发射的照相卫星可以提供高达50米的精度，俯视图，鸟瞰图，街景实拍……Google Earth和Google Maps功能实在太复杂，请读者自行研究吧。 5.在线文档 Google Docs可以自动保存文档或表格的各个历史版本。万一你需要找回删掉的草稿，这个功能就很方便了。虽然GoogleDocs在应用上还有很多局限，可能很多人用惯了Office等本地软件而不习惯网络化文档撰写，但GoogleDocs很多应用比Word等软件更方便，比如文档分享，协同撰写等功能，可以作为Office系列有效的补充。当多人协同撰写文章时，再也不用把Word文档作为附件传来传去了，一起在线编辑修改很方便。 6.航班查询 我想知道广州到法兰克福的CA6225离港和到港时刻，去Google 搜索：CA6225, 所有信息一目了然。此功能尚未完全本地化，国内航班可能收录不全。 7.外文翻译 想知道怎么和意大利人说“我不会说意大利语”吗？Google Translate 告诉你：Non parlo italiano. Google提供了数十种主流语言多向翻译,如果可以带发音功能那就更完美了。还可以翻译任何你不认识的外文网站。 8.移动设备查询信息 你和朋友打赌：1978年世界杯冠军是哪个队？偷偷地拿出手机打开m.google.com查询world cup winner 1978,哈哈……Google Maps, Gmail, GoogleReader等很多应用都支持手机访问。用中国移动的EDGE网络速度还很不错。现在带有内置GPS的手机价格也比较平易近人了，安装GoogleMaps就有了随身地图，出门不再迷路，打车不怕司机绕路……没有GPS的手机也可以使用，只是利用移动基站信号定位精确度差了一些。 9.遥望星空 Google Earth不仅能看地球，还能看太空！天文爱好者必备！利用Sky功能，你可以观看三维的星座图，超新星…… 10.强大的日历 如果你喜欢做事井井有条按部就班，GoogleCalendar绝不能错过。强大的日程规划，日历同步，日历分享功能都很好用。你可以和家人、朋友、同事互相同步共享日历，可以知道你身边的人的日程安排。约饭局，打牌，就靠它了。你的Google日历可以和电脑的Outlook同步，可以和你的智能手机同步。你还可以设置免费的手机短信定时提醒（中国移动用户可用，其他网络未测试） 11.查看股票 Google Finance——你的理财助手！可以直接输入股票代码或者上市公司名称，美股港股A股统统都有。不仅提供了实时的价格图表，还可以查看详尽的相关新闻信息。炒股票就靠它了！ 12.定制你的首页 iGoogle拥有无数的插件应用，生活工作娱乐学习一切信息一网打尽，你可以根据需要定制自己的“一站式信息中心”。 13.学术研究 Google Scholar可以查询到学术相关信息。写论文你再也不需要去图书馆翻阅那些堆积如山的材料了。查询organicchemistry即可查阅"有机化学"相关的论文、图书、出版物，给你写论文搞研究提供灵感和参考。与Google BookSearch有类似的毛病，中文信息贫乏，大部分资源都以英文为主。为了自己方便，练好你的英文吧，起码是英文阅读。 14.天气预报 输入weather beijing 天气信息一目了然。够简便不？ 15.浏览器工具栏 Google Toolbar IE和Firefox可用。拼写检查，自动提交注册信息等功能很方便实用。 16.计算器 27344.56*22.8直接敲入搜索栏即得结果。打开浏览器窗口方便还是用电脑内置的计算器方便呢？看个人喜好吧。 17.图片管理与分享 Picasa是目前最好用最方便的照片管理软件。这么说吧，你能想到的功能它基本全能实现。普通的去除红眼、照片修补、剪裁这些都是小菜一碟。速度是Picasa最大的特色，管理海量的照片非常简便。Picasa在线相册与管理软件无缝集成，免费提供1G存储空间，你可以把自己的照片上传分享给朋友们，或者在论坛,Blog嵌入自己的图片。说到在线相册就不得不提被Yahoo收购的flickr,哪个更好用呢？看个人习惯吧。什么？你用QQ相册？那个……随便你。 18.单位转换 很多时候2秒钟可以做到的事情如果使用了错误的方法可能要2分钟。比如：想知道1.45公斤是多少磅，你怎么做？有无数种方法可以换算出结果，最简单的办法是：Google搜索1.45 kilos in pounds.类似地，华氏温度与摄氏温度转换，英里转换为米……日常生活中经常碰到这些小事，下次再遇到类似情况记得使用Google.中文谷歌的本地化搜索更方便，你可以直接输入自然语言查询，打开g.cn, 输入“1英里是多少米” "1000日元是多少美金"试验下吧。 Google的服务多到令人发指，想要全都介绍完3天3夜也不可能，也是没有必要的。去Google大全自己挑感兴趣的研究吧 http://www.google.com/intl/en/options/。

http://www.techradar.com/news/in ... to-analytics-472634



from TechRadar: All Latest Feeds

Things change so quickly on the web. When I started working at software firm Urchin in 1996, web analytics was a niche product, important to (and understood by) perhaps a handful of people at an organisation.

When Google bought Urchin in June 2005 and launched Google Analytics later that autumn, the industry was moving away from expensive, complex tools in favour of free, easy-to-use ones, and these are quickly becoming more capable than those of the previous generation.

Analytics has also expanded to encompass a larger tool set and conversion process. It includes offline data sources and multivariate testing solutions. Perhaps the largest shift is that virtually everyone is now aware of and able to afford a quality web analytics and multivariate testing platform.

Getting started

You can sign up for Google Analytics at google.com/analytics. From there, you can create a new, free account. If you advertise on Google's AdWords system, you can also sign up for Analytics from within your AdWords account. Google Analytics has been closely integrated into your AdWords account under the new Analytics tab: click the tab and follow the instructions to start tracking AdWords campaign data and ROI information.

The Tracking Instructions page that appears contains the tracking code that you'll need to paste into each page of your site. Before doing so, you might want to complete a couple more steps to make sure Google Analytics collects the most relevant data for your site. You can configure your profile by clicking Edit in the Website Profile table.

Set the default (or index) page of your site. This will allow Google Analytics to reconcile log entries for www.example.com and www.example.com/index.html, for instance. These are in fact the same page, but are reported as two distinct pages until the Default Page setting has been configured.

Does your site use dynamic session or user identifiers? You can tell Google Analytics to ignore these variables and not count them as unique pages. Enter any query parameters you wish to be excluded, separated with commas.

To enable ecommerce reporting and the Ecommerce Analysis report set, select Yes. If your website is designed to drive visitors to a particular page, such as a purchase or email sign-up page, you can track the number of successful conversions using 'goals' and 'funnels' in Google Analytics. A goal is a website page a visitor reaches once they have made a purchase or completed another desired action, such as a registration or download. A funnel represents the path that you expect visitors to take in order to reach their goal.

Defining these pages enables you to see how frequently visitors abandon goals (and where they go instead) and the value of the goal. Each profile can have up to four goals, with a defined funnel for each. You can begin defining goals and funnels by selecting a profile and clicking Edit from the Analytics Settings page.

Hearts and minds

Google Analytics is not only a way to learn about customer behaviour, it can reveal something that's even more important: customer intent. Analytics data provides a peek into the hearts and minds of your customers and their needs and wants.

How did your visitors arrive at your site? For those who came through a search-engine query, a list of search terms will tell you what they were seeking. For example, shoe shoppers may be looking for Nikes but not Uggs; Clarks but not Donna Karan. You may therefore discover that part of your site is on target for visitors' needs, while the other half isn't. Similarly, Google Analytics can give you a list of 'referring URLs', websites that send you traffic. You can infer, for instance, that visitors coming from happycoupons.co.uk will have a different goal (making savings) than those coming from a manufacturer's retail link page (finding out about product features).

What are visitors looking for? Your checkout page tells you only where you've succeeded – not where you've missed an opportunity. Consider Best Buy's experience stocking a portable refrigerator to chill beer in the US. At first, they stocked it only during the Super Bowl. But search keywords reports revealed that shoppers still looked for the product code well into the baseball season – yet they couldn't find anything on the site.

Other key data that goes beyond conversions is the 'cart abandonment' rate: the percentage of customers who put items in the cart but leave your site before checking out. This crucial metric of your site's ability to close sales may indicate that something's amiss with your checkout process.

Where are your visitors landing, bouncing, and viewing? It's often assumed user experience begins on the homepage, and this misconception drives many an ecommerce site to waste hours of design work in the wrong place. Search engines dig deeper into ecommerce sites, bringing visitors to not just 'electronics', but also televisions, MP3 players or sat navs. Analytics data will tell you where your real 'homepages' reside, so you can focus your design work there. Curious? Just take a look at the 'Top Landing Pages' or 'Top Entry Pages' report in your Web Analytics tool.

Conversely, analytics will tell you which landing pages have the highest bounce rate – ie on which did people land, look around and quickly leave? This data tells you which of your pages are letting your customers down, and can also help with your redesign, since you can infer intent through the list of keywords and referring sites.

Web analytics can also show you the top viewed pages: information that's often overlooked. While you may consider yourself in the business of selling products, most of your hits could represent people reading customer reviews. Or perhaps you're selling 10 lines of products, but two of them show especially high traffic. Knowing what interests your customers will help you design a site that better meets expectations.

Analytics can help you understand what drives performance up or down. Earning $15,000 in the last 24 hours is good; knowing what drove that surge is even better. Ecommerce tracking shows the number of orders placed, the value of those orders, and more, by hour, day, week and month. By segmenting your data over different time lines, you can see both seasonal trends and more subtle buying habits that could otherwise go unnoticed.

Putting this information into practice takes not just creativity, but also a willingness to experiment. This spirit of adventure comes through on some of the most successful retail sites. Crutchfield (crutchfield.com) has taken the unorthodox approach of putting its checkout cart on the left side of the screen. Is that a good idea? Analytics reports have confirmed that it is – at least for them. Wal-Mart commonly puts products on its website that are unavailable in its stores. When those zebra- patterned bed sheets prove they have a following, the company understands the demographics enough to place them in targeted store locations.

Recent changes

Earlier this year we redesigned the Google Analytics site. The goal was to make it easier to discover information relationships via navigation and visualisations. We created a customisable dashboard and introduced sparklines. We developed new graphing tools and a new type of date slider, which make it easy to see spikes and dips in traffic as you set date ranges. And one of the most popular new features is one of the simplest: the ability to email reports and schedule these emails so that information can be easily shared with key stakeholders in your organisation.

New visualisations have been among the most popular features. You can now view many reports by hour or day and graph data by day, week or month. And we've made it easier to compare visits to conversions. You can also graph two metrics against each other over time so, for example, you can compare the number of visitors and the bounce rate for a certain week, or see if visitors who come to a site through AdWords spend more or less time on your site than visitors overall.

We've also added a new ga.js tracking code. This pagetag allows for more flexibility and customisation. It's just as easy to install as the old code, but enables more seasoned users to track ecommerce transactions in a more readable way and make use of advanced tracking features. We've also added a Google Analytics codesite (code.google.com/apis/analytics/docs/) to help you take advantage of documented customisations that have been made to the tracking code.

If you have content behind a security firewall, an intranet or an internal network that prevents you from using Google Analytics, you may also want to consider Urchin software. You can configure it to fit your own requirements and process/reprocess log files as frequently as you wish. Urchin is also great for intranets, since it allows the analysis of firewall-protected content, such as corporate intranets, without any outside internet connection. You can even track your site with Urchin and Google Analytics combined.

One of the coolest things we've recently added is industry benchmarking. Still in beta, it enables you to see how your site's data compares to others'. For example, if you have a travel website and you get a spike in traffic on Mondays, you may want to know whether other travel sites get that same spike. We don't share individual data with competitors, but bucket data into industry verticals and then anonymise and aggregate it.

Finally, Website Optimizer is a free tool that complements the functionality of Google Analytics to hone your site further. You can create different versions of your web pages, and Google then splits your traffic automatically, so your visitors tell you which version they like best. Things you might consider changing include images (bigger, smaller, colour, black and white, with models, no models); headlines (questions, shorter ones, emphasising different points); calls to action (different button designs and copy) and layouts (three columns, two columns, one long scrolling column).

Test a few big changes, not several small ones. A good rule of thumb is one page variation for every 100 conversions. So if you get 300 conversions per month, test up to three variations, including your current page. Run your test for at least two weeks. Don't jump to conclusions: make sure the data has an opportunity to normalise.

Make testing an ongoing process. Once you find a winner, keep trying to beat it. Remember that not finding a winner can be helpful, too, since you learn what doesn't work and you protect yourself from making changes that could have permanently harmed your site's performance.

FROM: http://internet.solidot.org/article.pl?sid=08/10/04/2338209&from=rss
35公里 写道 "提起 Google 的下一代 Web 平台 Google Gears，人们对它通常的误解是离线Web应用。然而事实上，Google 的野心远不在此，这个浏览器扩展拥有比离线应用多得多的使命。Google Gears 面世已经超过1年了，最早的版本发布于2007年5月。Google Gears 主要版本历史如下，但总体来讲，一共经历了4个主要版本，每一个版本都有新增的功能。最近一个版本发布于今年8月。Gears 的总体目标是为浏览器带来桌面功能，这是通过为浏览器提供相应扩展实现的，目前支持 Google Gears 的浏览器有 Firefox, Safari, IE，支持的平台包括 Windows, Windows Mobile, Mac OS, 以及 Linux。随着 Google 自己的浏览器 Chrome 的发布，Chrome 用户甚至不必费心去安装这个扩展，Gears 已经内置在 Chrome 浏览器中。 "
Google Gears 的长期路线非常明确：随着浏览器越来越强大，在 Gears 一类的技术的帮助下，人们越来越不必将软件应用安装到桌面。但在实现这个目标之前，Gears 以及类似技术需要在浏览器中真正实现桌面功能。目前，我们已经走到了哪一步？目前，Gears 可以帮助开发者在以下几个方面改善 Web 应用：

• 客户端数据库存储 - 多数交互式网站靠数据库采集，组织，分发信息内容，而传统模式下，几乎所有的数据库都位于服务器端，用户即使做一个小小的动作，都需要在数据库和客户端往返。使用 Gears 数据库 API，网站可以将数据库建在用户的电脑上，使得对数据库的操作直接在本地进行，实现更好的速度与离线功能。
• 客户端网页服务 - Gears 可以将你自的客户端电脑变成网页服务器，当远端的网站服务器无法到达的时候，LocalServer API 可以将在线时缓存的网页推出，这个功能也可以用作加速。
• 桌面快捷方式 - 要让 Web 程序象桌面程序那样工作，它们至少应当可以象桌面程序那样打开。Gears 很容易帮你在桌面上创建 Web 程序快截方式，可以双击打开运行。Gears 让 Web 程序的桌面快截方式比传统的 Web 快截方式更直观，图形质量更高，支持多种尺寸，甚至可以多层堆积，在诸如 Gmail 一类的 Web 应用中，可以通过这种方式直接在快截图标上看到你有多少封未读邮件。
• 多文件同时上传 - 在正常情况下，如果你要向网站上传多个文件，你只能一个一个上传，除非使用一些基于 Flash 或 Java 的扩展。使用 Google Gears 你可以实现一次上传多个文件。
• 地理信息 - 对于那些支持地理信息的移动设备，Gears 可以实现直接在浏览器中获得你当前的位置，geolocation API 可以随时获悉你的地理位置，当然，实现必须通过一个特殊的对话框获得用户的允许以防泄露隐私。
• 后台处理 - 对于那些使用了大量 JavaScript 的 Web 程序，你必须等待 JavaScript 执行完才能继续进行。使用 Gears 中的 WorkerPool API，你可以让那些耗时的 JavaScript 在后台运行，使你的 Web 程序运行更流畅。

Google Gears 开发团队还将实现 Gears 的以下功能：

• 进度条 - 在上传大文件的时候，你需要知道真实的进度，在传统 web 程序中这是无法实现的，除非使用基于 Flash 或 Java 的部件。Google Gears 可以让你看到真正的进度条。
• 断点续传 - Google Gears 将来可以在文件上传中实现断点续传。
• 屏幕通知 - Growl 以及微博客等系统的桌面客户端，如 Twhirl 可以定制桌面通知窗口，在屏幕的右下角滑出，Gears 将在所有网站实现这样的功能。

在更远的将来，我们还可以看到 Gears 对复杂 3D 图形加速，直接使用客户端电脑中的图形加速卡。上传功能可以直接结合菜单系统，在文件上点右键直接上传文件。Web 程序可以随着系统一起启动。 

以下视频来自 Google 的 Chris Prince 在5月份的 Google I/O 开发者大会中做的一个演示，可以很好地对 Google Gears 做一诠释。 

Nik Cubrilovic 的 next generation web 也对下一代 Web 平台之争做了很好的讲述。

10 hot Web redesigns of 2008from Neowin Back Page News
It may be a little too early to do a roundup of the best redesigns of 2008 like we did last year, but with Thursday's one-two punch of new looks for social sites Twitter and FriendFeed, it's a good chance to take a look back at some of this year's redesigns and talk about what was changed or fixed.

I'vepicked 10 of my favorites below, listed in no particular order. Seealso the honorable mentions section at the bottom of the post, whichincludes content sites or other places that didn't quite make the cut.

1. Twitter


Twitter'snew look isn't all that different from its old look, except for aslightly more rounded feel and the inclusion of tabs on the right side.

Twitter's redesignwas a twofold change: one part to simplify the interface, and anotherto reduce the resources needed to host the site. Now when users hopbetween various functions it doesn't reload the entire page, meaning afaster experience and less data to serve.

The most interestingpart of the redesign is actually something we don't know about. Thetabbed interface on the right was apparently set in place to make roomfor additional features as they become available. It could be the newthings from Twitter itself, or the foundation for specialdeveloper-created applications users will be able to use withoutleaving the service.

2. Facebook


Facebook'snew look blends in user chat with an applications start bar. Moreimportantly it's made it easier to sort through and add content.

The"new" Facebook was one of the most drastic changes of any site thisyear. Like Twitter, tabs took center stage, as did the chat whichshares screen real estate with what's essentially the "start" button onWindows. This new menu let users launch networked applications from anypage they're on. The change also embraced widescreen displays, makinguse of the extra room to let users build out the experiencehorizontally instead of having to scroll up and down.

You can read more about it, and the user backlash, here.

3. FriendFeed


FriendFeed'snew look puts the navigation almost entirely on the left-hand side ofthe screen, and uhh, it doesn't normally have a pirate theme.

FriendFeed's big changemoved the navigation from the very top of the screen to the side, andallowed the posted content to make full use of widescreen displays.More importantly, it made room for additional features withoutsqueezing things together, much like Twitter's. One of the mostinteresting aspects of the new look was that the company let any userwho wanted to test it with the use of a special URL, then pushed out the look to everyone in less than a month.

4. Yahoo.com


The new Yahoo will cut down on some of the clutter and include widgetized content akin to the company's My Yahoo service.

Yahoo'sbig, bold new look is the only one on this list that's not actually outyet. The Web giant will be letting users add customized bits and piecesof content, much like users are currently allowed to do on thecompany's My Yahoo service (whose look was also tweaked this year).The big difference is that this custom content will sit alongsideYahoo's constantly updating stream of news, photos, and links fromaround the Web.

Screenshots of the new look were posted by Yahoo on Wednesdayand the company has already begun testing it on a select percentage ofusers to work out some of the kinks. Look for it in the coming months.

5. MySpace


MySpace's updated look is a lot cleaner than its old one, and puts the focus on user-generated content from its members.

MySpace's redesign took place in mid-June.It was a play to get some of the service's features and user-generatedcontent into the limelight, and away from the sea of links that existedbefore. More importantly, it added things like better search, a profileeditor that removed the need for hard coding, as well as ahigh-resolution media player for its video service.

6. Digg/Digg mobile


Theupdated Digg.com and mobile version of Digg improved upon existingdesigns while keeping the core of the service generally the same.

Digg's big change this year was the inclusion of a recommendation enginewhich completely re-tooled the way users parsed through newly submittedstories. On one hand, it improved your chances of finding content you'dbe interested in based on past digging, however, it came at the expense of the cloud view, which simply grouped together all the story headlines in one mass.

The same release brought with it a re-do of Digg mobile.Previously the site was only optimized for iPhones, but the new versionlet users on any handset view and vote on the site's top stories.

7. MobileMe (formerly .Mac)


MobileMe'sWeb mail looks downright modern. The aging .Mac platform was replacedwith a slew of cloud-powered Web apps that sync up with your variousdevices--at least when the system is working.

With the announcement of MobileMe at WWDC '08in early June, and subsequent release in mid-July, Apple effectivelykilled off .Mac in place of a handful of updated Web apps. One of thebiggest changes was in its Web mail service which joins an onlinecalendar, file and contact manager which are all accessed within asingle interface.

Despite its slicker look, the core functionality of the service suffered substantial problems in the first month or two, including the Web mail which was unavailable for some users.

8. LinkedIn


LinkedIn's redesign was not a drastic one, but complimented some of the utilitarian aspects of the service.

LinkedIn's February redesigncame hot on the heels of a two-month long beta test for registeredusers of the site. Aimed mostly at integrating applications designed bydevelopers, the site made room for growth with a left-hand side toolbarand tabs--much like Facebook's design before its facelift.

9. Delicious


Thenew Delicious is dramatically different from its former self.Everything is far more angular, and tag management has been drasticallyimproved.

Yahoo's Delicious unveiled its new look to all users in late July. Users had been testing it in private beta since late 2007 (our look here). The big change was not only in the name, which ditched the hard to remember de.licio.us,but also what was going on behind the scenes to make it more responsiveand scalable. The site also got a complete overhaul of its searchengine, making it easier to dig through old stories, tags, and users.

10. Last.fm


Last.fm's new look lets you start getting artist recommendations without having to sync up and share your current music library.

Music social network Last.fm underwent a complete redesign in mid-July.With the new look came the capability to get recommendations simplybased on dropping in a few band names instead of having the siteanalyze the user's music library and ratings. Like MobileMe, theservice also suffered some stumbles with unreliability.

Honorable mentions for other sites: CNET, Engadget, Wall Street Journal online, TechCrunch, CenterNetworks, Mashable, Bebo, Revision3, and coComment. If you think we left one off drop us a line.

先研究一下采用DZ GBK版本全新安装创建的数据库编码格式和采用DZ UTF8版本全新安装创建的数据库编码格式有什么不同吧。
不同之处在于这个数据库的编码格式（查看db.opt），以及每个表的缺省编码格式，还有每个字段的缺省编码格式，（查看表结构的缺省字符集选项）都不同。


导出：mysqldump

-u[username] 指定用户名
-p[password] 指定密码
-q 用于导出大数据库（采用行读取，代替一次性导入内存，用内存做缓存，再一次性写入的下数据库导出方式）
-e 使用多行insert语句代替直接插入值的写法，生成的文件小，加载速度快
-x 导出为XML格式
--compatible=databasenameversion 指定兼容于最低版本
--default-character-set=charset_name 指定导出文件所采用的文件编码格式，缺省使用utf8，老版本缺省latin

MySQL\bin>mysqldump -uroot -ppassword -q -e databasename > filename.sql
导出当前数据库结构及数据为一个UTF8编码的文本本件

再用EmEditor查看这个文件，发现文件编码格式是UTF8的，采用UTF8格式打开不存在乱码（这很重要，我转换汉字没有变成乱码，不知道为什么，不过如果你转换了发现汉字是乱码，说明采用utf8导出不成功，应该采用数据的本来编码，在本例中是gbk，指定这个--default-character-set=gbk来导出，然后再用emeditor直接另存为utf8格式，就算转换编码完成了）。
但是其中创建每个数据表的语句则指定了缺省字符集是GBK。我决定把这个语句中的gbk替换成utf8（一共替换了93次）这个需要把左右指定gbk的地方替换成utf8，我的emEditor在替换大于1G的文件的时候出错，说是替换成功了，但是实际上什么也没改！

创建一个新的数据库databasenameutf8指定编码格式为utf8 （db.opt）
MySQL\bin>mysql -uroot -ppassword databasenameutf8 < filename.sql

由于文本文件我没改成功，所以进入新建立的数据库，发现使用的还都是gbk编码，进入phpAdmin的管理界面逐一手工改掉了。


通过phpmyadmin建立一个新库，库名：test2 ，采集字符集设定为utf8-general-li

再将刚才生成sql文件导入新数据库

D:\PHPServer\MySQL\bin>mysql -uroot -p –default-character-set=utf8 test2 < d:/zxs.sql

还是不一样的，比如数据库放在北美服务器，北美和国内服务器之间速度比较快，但是国内用户直接访问北美服务器慢，这时候，用户可以通过访问国内服务器来获得比较快的速度。

当然，如果我们有一个中心服务器如果能满足所有地区的访问速度的话，就不用搞这么复杂了。

标准ACL只检查数据包的源地址; 扩展ACL既检查数据包的源地址，也检查数据包的目的地址，同时还可以检查数据包的特定协议类型、端口号等。
标准ACL好比粗心的看门人，只看你是哪里来的，而不管你去做什么。为了避免误杀，最好放在最靠近目的端。
而扩展ACL因为比较精确，所以越放在前面越能挡住无效的流量。

这是BIND9的核心功能，用于做区域访问分割和负载均衡用的，也就是说对于同一DNS解析请求(比如www.freeoz.org), 根据不同的请求者IP解析得到的www.freeoz.org的IP地址是不同的。就像大家都访问www.google.com,中国的用户得到的IP地址和澳洲的用户得到的IP地址是不一样的，google的DNS服务器会把最靠近终端用户的google server ip作为相应，从而做到负载均衡的效果。


这个功能还可以用来：
1. 对内网和外网的DNS解析隔离 (如yourcompany.com，从公司内网看到的server和外网看到的server是不同的，尽管用的是同一个名字)

2. 屏蔽某些IP(段)的解析,把不受欢迎的IP请求用错误的或者虚假的IP作为相应(还记否，google.com曾经在天朝被指向过baidu.com 呵呵)

3. 。。。

谢谢楼主分享，长见识了。

说真的，我觉得现在大学的课程里应该加入Google技术这一科（最好是double module）当然我说不是中国的大学。
