ecos RTOS 原理介紹和應用開發The design philosophy of eCos was to augment an open-source RTOS (which meant no per-unit royalties) with source-level con?guration tools that would enable embedded developers to scale their RTOS from hundreds of bytes to hundreds of kilobytes without needing to manu- ally change a line of source code.

Wireless penetration has witnessed explosive growth over the last two decades. Accordingly, wireless devices have become much denser per unit area, resulting in an overcrowded usage of wireless resources. To avoid radio interferences and packet collisions, wireless stations have to exchange control messages to coordinate well. The existing wisdoms of conveying control messages could be classified into three categories: explicit, implicit, or hybrid.

As we enter the next millennium, there are clear technological patterns. First, the electronic industry continues to scale microelectronic structures to achieve faster devices, new devices, or more per unit area. Secondly, electrostatic charge, electrostatic discharge (ESD), electrical overstress (EOS) and electromagnetic emissions (EMI) continue to be a threat to these scaled structures. This dichotomy presents a dilemma for the scaling of semiconductor technologies and a future threat to new technologies. Technological advancements, material changes, design techniques, and simulation can fend off this growing concern – but to maintain this ever-threatening challenge, one must continue to establish research and education in this issue.

sheerdns is a master DNS server whose zone records are stored on a One-Record-Per-File bases. Because of this, it is the simplest of any DNS to configure, the easiest to update, and the most efficient for networks that experience a lot of updates (for example master servers for dynamic IP address ranges). You never have to restart it; any updates are available immediately without having to notify the sheerdns process. 來源: http://freshmeat.net/projects/sheerdns/?topic_id=149 sheerdns是一個主DNS服務器，它的域記錄保存在一個One-Record-Per-File（每文件一個記錄）的庫中。因此，它是最簡單的DNS配制，最容易更新，對于有大量更新的網絡（如動態IP地址范圍的主服務器）來說它是最高效的。你不必重新啟動它，任何更新不用通知對應DNS進程就可以立即生效。

在此unit中，實現了對于QQ自定義IP數據庫(MyIP.dat)的IP數據庫的檢索。 參考了冷風(coldwind@citiz.net)實現對于純真網絡的IP數據庫的讀取。 附帶的MyIP.dat是南京大學的內網ip分布。

The zlibex.pas unit included in this archive will work with delphi 5, 6,and 7. if you previously downloaded my delphi 5 unit, you will notice that the unit has been renamed. this was done because borland included in its delphi 6 and 7 lib directories a zlib.dcu file and i felt it was more correct to rename my unit and force developers to have to update their code than to make developers worry about the possible file contention in delphi 6 and 7.
