从社会化媒体、智能设备到云计算，技术改变着个人与企业的方方面面。Gartner, Inc. 认为CxO们对这些技术如何融入企业或如何改变企业的评估至关重要。Mr. Sondergaard说，未来20年变化的焦点在于从信息中提取情报（intelligence drawn from information）. 信息是21实际的“石油”，将以全新的方式驱动我们的经济发展。

Gartner认为在未来10年，以下四个趋势将改变IT和经济方式：

• 云 (Cloud)
• 社会化对商业的影响 (Business impact of social computing)
• 环境相关 (Context aware computing)
• 基于模式的战略 (Pattern based strategy)

云(Cloud)

从早期的网站托管到如火如荼的Saas商业模式，云计算在过去的10年中随着硬件、互联网技术和性能的大幅提升发展迅速。微软、Google、IBM等大型IT公司无不涉水该领域，与云计算相关的并购也风起云涌。毫无疑问，未来的应用将围绕云计算展开。

社会化对商业的影响 (Business impact of social computing)

以Facebook, Twitter代表的社会化网络（国内的人人网、开心网等）成为继搜索引擎之后又一商家攻城略地的战场，相比以往搜索引擎的以内容匹配广告的模式相比，社会化网络为商家提供了更加准确的目标客户群体，商业活动自然更加精准。而互联网上的种种应用，也无不打上了SNS的烙印。未来的互联网，将再现或再造一个虚拟化的社会，商业模式也将因此发生巨变。

环境相关 (Context aware computing)

以基于位置的服务(Online Maps + GPS)为代表，环境相关的应用正在取代传统应用赢得用户的青睐。在用户端节省了操作时间，简化了应用复杂度，也带来了前所未有的体验。除此之外还有众多智能手机搭载或即将搭载的磁感电子指南针、陀螺仪、紫外线感应器等设备，为设备带来了更多感知环境的可能。而未来的应用，也将与环境融为一体。

基于模式的战略 (Pattern based strategy)

基于模式的战略提供了一个可以主动从传统或新兴数据源中寻找模式、对其影响力建模并适应模式的框架。基于模式的技术有社会化网络、环境相关的技术和预测性分析工具。IT领导者将能够在快速变化着的数据源头中寻找模式，并为未来某些可能性建立模型。总的来说，就是具备先知先觉的能力。

在写下第一段文字的时候，距离美国东部时间12:30pm还有8分钟。从网上各路消息来看，其起源源于NASA官网上一则新闻发布会的预告。 “WASHINGTON — NASA will hold a news conference at 12:30 p.m. EST on Monday, Nov. 15, to discuss the Chandra X-ray Observatory’s discovery of an exceptional object in our cosmic neighborhood.”官网将其称之为Exceptional object，没有所谓“震惊”甚至“全人类”的意义。估计又是媒体借机炒作吧。猜想应该只是普通的天象新闻发布会而已。

媒体普遍倾向于推断NASA此次公布的发现有关于世界末日时间或与外星生命有关。但是从NASA官网通知来看，应该是钱德拉X射线天文台在我们地球附近发现的异常物体。

北京时间2010年11月16日 凌晨00:30 (美国东部时间12:30pm)

NASA Media Channel 直播了新闻发布会，NASA借助Chandra X-ray Observatory观测到了一个最年轻的，非常近的黑洞存在的证据。这是一个30年前才形成的黑洞，为研究提供了很好的机会。这个30岁大的黑洞是SN 1979C超新星，存在于galaxy M100（好专业…不懂）距离地球5000万光年的地方。

……

简单总结下，美国宇航局（NASA)在发布会上刚刚宣布利用钱德拉X射线望远镜发现5000万光年外的年轻黑洞，仅有30岁，曾在1979年观测到了超新星爆炸，现在成了黑洞。

大概就这样吧，反正不是外星人，Q群里有人问跟我们有什么关系么，嗯，是，还是赶紧去做晚饭吧，饿肚子了。媒体就知道炒作，还震惊人类……

For the last two days, I’ve been trying from installing Android on my Samsung i900 phone to setting up an Android Emulator on my Windows 7 laptop. I even almost make my decision to buy an Android smartphone. But eventually, all I want is to try out Android amazing apps in Android Market. That’s all because of no listing available to normal PC browsers. And the standard Android Emulator doesn’t contain the Market.

Finally, I found a way to run Market on Android Emulator. It’s actually easy but a little bit tricky – to replace standard Android SDK system.img with a developer image from HTC developer website. I will show you now.

Step 1. Install Android SDK on your OS. I did this on my windows 7.

Visit Google Android Developers at http://developer.android.com/sdk/index.html and download the SDK installer.

Then you need to first download SDK packages. When you start the SDK manager, it will prompt to download or update SDK packages. Just follow the instruction. It will take a while because about 800M data need to be downloaded totally, including all SDKs from Version 1.5 to 2.2.

Step 2. Create a Virtual Devices.

Choose a target system of Android 1.6. Because on the HTC developer website, only 1.5 and 1.6 system images are available to download.

Step 3. Download HTC Developer system image.

Visit the website: http://developer.htc.com/adp.html and scroll down to section“Download the Image Packages”. Download the one I marked in the screen shot below.

Step 4. Copy system.img to your virtual device folder.

Extract the system.img file from the downloaded zip file. Copy it to your virtual device folder – located in <username>/.android/avd/<avdname> . By default, Android Emulator will load a default system.img from SDK folder. But when you copy your downloaded system.img to the AVD folder, it will use this one.

Finally, start your virtual device and setup your personal account if it’s the first time using the virtual device. Then you will see the market on the “desktop” of your Android.

It’s really cool because I don’t need to buy an Android phone just for try out apps. Just enjoy it.

In this tutorial, I will show you how to install and remove applications (APK files) on the Android Device Emulator which is bundled as part of the SDK. If you are a developer, you may often want to install applications on the Android Device Emulator for testing before you publish them. You may also want to run certain applications on the emulator before installing them on your device.

To install / remove applications on the Android Device Emulator, you need to download and install the SDK from http://developer.android.com/sdk/. After downloading the file, just extract the archive into any folder. You won’t need Eclipse or any IDE.

Before installing / removind apps on the emulator, you should also set the PATH environment variable to point to the tools directory in the Android SDK directory so that you can use ADB directly on the command line.

To do so, go to My Computer – > Right Click – > Properties – > Advanced – > Environment Variables. Select the PATH variable from the System Variables and click Edit. Add the location of the tools directory to the existing string. Ex: C:\Android\Tools and save the changes.

Installing APK Files on the Android Device Emulator.

Now download the APK file you want to install and save it in the tools directory (preferably).

Open Command Prompt by Start – > Run – > CMD and navigate to the tools directory.

type: ADB INSTALL APKFILE.APK where APKFILE.APK is the name of the application you want to install.

If there are no errors, then the application has been successfully installed. You can now just run the emulator directly to access it.

Removing APK Files from the Android Device Emulator.

To remove the installed APK files,

Just go to Command Prompt by Start – > Run – > CMD and navigate to the tools directory.

type: ADB SHELL RM DATA\APP\APKFILE.APK where APKFILE.APK is the name of the application you wish to remove.

If there are no errors, the application has been removed.

Android自上市以来在和iPhone走了完全不同的两条路，Google把手机制造的业务留给了行业上游，自己则获得了最重要的平台、用户以及渠道资源。在2009年Q3，Android市场占有率仅为3.5%，而一年之后的2010年Q3，Android的市场占有率已经达到25.5%。也许明年的Q3，Symbian也要被轻松超越。

Gartner在报告中指出，Android在全球范围内的市场占有率已经非常惊人，但是在北美更是具备主导地位。有趣的是，Gartner说，Android在Q3的成功要归功于iPhone 4，看来iPhone 4的确是不那么乐观。

从这张表格中我们可以看到，Android OS在智能手机市场上是一年以来唯一增长的产品，这说明Android的强势蚕食了市场上所有的竞争对手，四面树敌的Android在接下来一年恐怕不好过了。
