郵件系統(tǒng)是Linux網(wǎng)絡應用的重要組成,一個完整的郵件系統(tǒng)包括三個部分:底層操作系統(tǒng)(Linux Operation),郵件傳送代理(Mail Transport Agent,MTA),郵件分發(fā)代理(Mail Delivery Agent,MDA),郵件用戶代理(Mail User Agent,MUA)。 Postfix是一個非常優(yōu)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(fā)而推出反垃圾郵件網(wǎng)關產(chǎn)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(fā)往自身的垃圾郵件,而且還防止了自身被惡意利用發(fā)送垃圾郵件。Postfix 實現(xiàn)了目前所有主要的MTA過濾技術。postfix是Wietse Venema在IBM的GPL協(xié)議之下開發(fā)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。

這些天新殼大爆發(fā)啊,我也來湊個熱鬧。 又是一個自娛自樂的產(chǎn)物,和netsowell發(fā)布過源碼的那個不一樣,這個殼90%的代碼是用delphi寫成的。 僅在win2k+sp4上測試過,不支持9x系統(tǒng)。因為用了一個可能不安全的隱藏oep的方法,xp系統(tǒng)上有可能會出問題。 沒花,沒anti代碼,適合初學者了解殼。 現(xiàn)在只能壓縮exe文件。 壓縮包里含源碼,算是為這里的delphi初學者的小禮物。

If you have programming experience and a familiarity with C--the dominant language in embedded systems--Programming Embedded Systems, Second Edition is exactly what you need to get started with embedded software. This software is ubiquitous, hidden away inside our watches, DVD players, mobile phones, anti-lock brakes, and even a few toasters. The military uses embedded software to guide missiles, detect enemy aircraft, and pilot UAVs. Communication satellites, deep-space probes, and many medical instruments would have been nearly impossible to create without embedded software.

Commercially available active noise control headphones rely on fixed analog controllers to drive "anti-noise" loudspeakers. Our design uses an adaptive controller to optimally cancel unwanted acoustic noise. This headphone would be particularly useful for workers who operate or work near heavy machinery and engines because the noise is selectively eliminated. Desired sounds, such as speech and warning signals, are left to be heard clearly. The adaptive control algorithm is implemented on a Texas Instruments (TI™ ) 1 TMS320C30GEL digital signal processor (DSP), which drives a Sony CD550 headphone/microphone system. Our experiments indicate that adaptive noise control results in a dramatic improvement in performance over fixed noise control. This improvement is due to the availability of high-performance programmable DSPs and the self-optimizing and tracking capabilities of the adaptive controller in response to the surrounding noise.
