Modern electronic systems solve so many difficult problems that they often seem like magic. Nonetheless, these systems all have thesame basic limitation: they need a source of electrical power! Most of the time this is a straightforward challenge for the electronicdesigner, because there are many power-delivery solutions. Yet sometimes a device has no direct power source, and running wiresor replacing batteries is impractical. Even when long-life batteries are usable, they eventually need to be replaced, which requires aservice call.

郵件系統是Linux網絡應用的重要組成,一個完整的郵件系統包括三個部分:底層操作系統(Linux Operation),郵件傳送代理(Mail Transport Agent,MTA),郵件分發代理(Mail delivery Agent,MDA),郵件用戶代理(Mail User Agent,MUA)。 Postfix是一個非常優秀的MTA,她素以高效、安全的特點而著稱。Postfix是作者在UNIX上所見過的MTA中在反垃圾郵件(Anti- Spam或Anti-UCE)方面做得最好的一個,甚至有很多公司在Postfix代碼的基礎上進行二次開發而推出反垃圾郵件網關產品。MTA的反垃圾郵件功能,實際上就是在MTA處理過程中對會話進行過濾。這個過濾不但過濾了發往自身的垃圾郵件,而且還防止了自身被惡意利用發送垃圾郵件。Postfix 實現了目前所有主要的MTA過濾技術。postfix是Wietse Venema在IBM的GPL協議之下開發的MTA(郵件傳輸代理)軟件。和Sendmail相比Postfix更快、更容易管理、更靈活、更安全。

a sample WDM stream class video capture driver that supports two IEEE 1394 digital cameras. The same driver may be able to support other digital cameras that conform to 1394-based Digital Camera Specification from 1394 Trade Association. Digital camera supported by dcam.sys is a data source that produces digital image data without any other input connection. It manifests itself in a DirectShow graph as a WDM Streaming Capture Device and as a capture filter that has output capture stream supporting image sizes of 320x240 with a UYVY color space. Its de-compressor, Msyuv.dll, is part of the OS delivery, and it can convert image data format from UYVY to RGB16, RGB8, or to a Direct Draw surface if the video card supports UYVY format.
