一直比较关心RFID技术及其应用，没想到微软这家伙居然偷偷出了个如此了得的新概念计算机。

Channel 10放出了微软Surface计算机的视频，这是一台全触摸式的令人惊叹的创新计算机。微软称Surface计算机将最先作为公共服务出现在Las Vegas。随着产量的提升，价格也会慢慢降下来。建议大家都下载此视频观看一下，Surace意图将自身打造成服务终端，将各项服务整合在这个平台之下，实现的功能令人十分振奋。
在这段视频中，Surface电脑的市场营销主任Mark Bolger向我们解释了什么是Surface计算机。“这是一台什么计算机呢？这是一台将在每个宾馆、每个小卖部、每个娱乐场所都将出现的计算机。”

1. 多重触控（MultiTouch）
2. 基于RFID的图章
3. 和掌上移动设备的无缝连接、同步
4. 甚至可以感知你放到屏幕上的香槟是哪一年出产的

什么是RFID：
RFID，射频识别技术，Radio Frequency Identification的缩写
RFID first appeared in tracking and access applications during the 1980s. These wireless AIDC systems allow for non-contact reading and are effective in manufacturing and other hostile environments where bar code labels could not survive. RFID has established itself in a wide range of markets including livestock identification and automated vehicle identification (AVI) systems because of its ability to track moving objects.
RFID射频识别是一种非接触式的自动识别技术，它通过射频信号自动识别目标对象并获取相关数据，识别工作无须人工干预，可工作于各种恶劣环境。RFID技术可识别高速运动物体并可同时识别多个标签， 操作快捷方便。

RFID的基本组成部分：
标签(Tag)：由耦合元件及芯片组成，每个标签具有唯一的电子编码，附着在物体上标识目标对象；
阅读器(Reader)：读取(有时还可以写入)标签信息的设备，可设计为手持式或固定式；
天线(Antenna)：在标签和读取器间传递射频信号。

RFID技术的基本工作原理：
标签进入磁场后，接收解读器发出的射频信号，凭借感应电流所获得的能量发送出存储在芯片中的产品信息（Passive Tag，无源标签或被动标签），或者主动发送某一频率的信号（Active Tag，有源标签或主动标签）；解读器读取信息并解码后，送至中央信息系统进行有关数据处理。

一个RFID标签十分微小（甚至比盐粒还小），例如，办公室桌面上要快速找到一份文件在哪个位置比较困难，如果每个订书针上都可以放置一个RFID标记（Tag），然后我们要找一份文件只需要用个扫描器（Reader）就可以定位了。读写设备（Reader）可通过无线电讯号以一定的数据传输率与标签交换信息，作用距离可根据采用的技术从若干厘米到1千米不等。

将射频类别技术与条形码（Barcode）技术相互比较，射频类别拥有许多优点，如：可容纳较多容量、通讯距离长、难以复制、对环境变化有较高的忍受能力、可同时读取多个标签。相对地有缺点，就是建置成本较高。不过目前透过该技术的大量使用，生产成本就可大幅降低。

2005年初每标签的价格仍在30欧分左右，大批量（十亿个以上）生产的射频识别标签的价格可望在2008年降至10欧分以下。

在Baidu上搜索了下RFID，文章寥寥数片，不成气候，看来大陆还没有“热”起来。想必5年之后，RFID一定如同商品条形码一样被人们普篇认识。射频识别技术可应用的领域十分广泛，主要决定因素是该项技术在相应领域中的经济效益。经常提到的具体应用包括：钞票及产品防伪技术、 身份证、通行证(包括门票) 、电子收费系统，如香港的八达通与台湾的悠游卡 、家畜或野生动物识别 、病人识别及电子病历、物流管理等等。许多人把射频识别技术看作为继互联网和移动通信两大技术大潮后的又一次大潮。但是目前RFID在中国大陆，香港，台湾的发展远远落后于美国及欧洲，需要非常的努力方能赶上这次“新的浪潮”。

For all of us who feel only the deepest love and affection for the way computers have enhanced our lives, read on.

At a recent computer expo (COMDEX), Bill Gates reportedly compared the computer industry with the auto industry and stated, "If GM had kept up with technology like the computer industry has, we would all be driving $25.00 cars that got 1,000 miles to the gallon."

In response to Bill's comments, General Motors issued a press release stating:

If GM had developed technology like Microsoft, we would all be driving cars with the following characteristics (and I just love this part):

1. For no reason whatsoever, your car would crash . . . twice a day.

2. Every time they repainted the lines in the road, you would have to buy a new car.

3. Occasionally your car would die on the freeway for no reason. You would have to pull to the side of the road, close all of the windows, shut off the car, restart it and reopen the windows before you could continue. For some reason you would simply accept this.

4. Occasionally, executing a maneuver such as a left turn would cause your car to shut down and refuse to restart, in which case you would have to reinstall the engine.

5. Macintosh would make a car that was powered by the sun, was reliable, five times as fast and twice as easy to drive - but would run on only five percent of the roads.

6. The oil, water temperature, and alternator warning lights would all be replaced by a single "This Car Has Performed An Illegal Operation" warning light.

7. The airbag system would ask "Are you sure?" before deploying.

8. Occasionally, for no reason whatsoever, your car would lock you out and refuse to let you in until you simultaneously lifted the door handle, turned the key and grabbed hold of the radio antenna.

9. Every time a new car was introduced car buyers would have to learn how to drive all over again because none of the controls would operate in the same manner as the old car.

10. You'd have to press the "Start" button to turn the engine off.

Just try this command-line parameter:

googletalk.exe /nomutex

It's cool, isn't it?

Also there is a very interesting post on NeoWin.net on how to do conference calling with GTalk, It's a chain relay trick.

How to conference call:
Open up a copy of google talk on all computers with which you wish to conference. After one copy is opened make a new shortcut for google talk but at the end of it add /nomutex. If you installed it to the default folder then your shortcut should read “C:\Program Files\Google\Google Talk\googletalk.exe” /nomutex. Open 2 instances of the software on every user’s computer. After this start a chain: User 1 should connect on one instance to user 2. User 2 will connect on his second instance to user 3. User 3 will connect using his second instance back to user 1. With this chain everyone is connected to everyone.
Possible problems: Google will try to connect you with others on the same instance. To fix this just open a new instance. It seems that google will try to take calls on the newest IM client.
Note: You can also make a conference call with more people, just have need to have one less instance than the amount of people that exist.

Dear Pandora Visitor,

We are deeply, deeply sorry to say that due to licensing constraints, we can
no longer allow access to Pandora for most listeners located outside of the U.S.
We will continue to work diligently to realize the vision of a truly global
Pandora, but for the time being we are required to restrict its use. We are very
sad to have to do this, but there is no other alternative.

We believe that you are in China (your IP address appears to be
211.95.166.57). If you believe we have made a mistake, we apologize and ask
that you please contact us at

pandora-support@pandora.com

If you are a paid subscriber, please contact us at

pandora-support@pandora.com
and we will issue a pro-rated refund to the credit card you used to sign up. If
you have been using Pandora, we will keep a record of your existing stations and
bookmarked artists and songs, so that when we are able to launch in your
country, they will be waiting for you.

We will be notifying listeners as licensing agreements are established in
individual countries. If you would like to be notified by email when Pandora is
available in your country, please enter your email address below. The pace of
global licensing is hard to predict, but we have the ultimate goal of being able
to offer our service everywhere.

We share your disappointment and greatly appreciate your understanding.

Sincerely,

• WinSockExpert
  The writer seemed to stop develop this software long ago, and it's still in beta, many of the functions are not finished yet like Fileters. Still it's a good capture tool, it supports HEX/Text display switching and you can select a current process to capture. But you can not select multipule processes or start & capture a new process. WSockExpert DOES capture HTTPS sessions but it does not decode them. Also there seemed to be some problem with it's process injection that sometimes capture may fail and you could not start or pause a capture. Even it's captured destination IP address may not be accurate. Anyway it's the most popular capture tool in mainland China.
• Ethereal/Wireshark
  Tools like this is working on a very low OSI layer. Personally I do not recommand these tools for application-level packet capturing.
• Sniffer/Sniffer Pro
  How can I just capture a single process not my NIC?
• HTTP Watch Pro
  It's a wonderful tool which works as an IE plug-in. There is nothing to say about it's powerful function, the only problem is it could ONLY canpture IE while most of the time I am using Maxthon Browser.
• HTTPDebugger
  It's far better than WinSockExpert but it can not capture HTTPS sessions
• HTTPLook
  This tool looks good and does good, but not on Vista. Pity.

And finally I chose HttpAnalyzer. It meet all my demands:

• Capture just a process, start a process & capture
• Works with HTTP and HTTPS
• Not an IE plug-in
• Filter captured data
• Supports IE7 and Vista

That's it!
