Abstract: Many modern industrial, medical, and commercial applications require temperature measurements in the extended temperature rangewith accuracies of ±0.3°C or better, performed with reasonable cost and often with low power consumption. This article explains how platinumresistance temperature detectors (PRTDs) can perform measurements over wide temperature ranges of -200°C to +850°C, with absolute accuracyand repeatability better than ±0.3°C, when used with modern processors capable of resolving nonlinear mathematical equation quickly and costeffectively. This article is the second installment of a series on PRTDs. For the first installment, please read application note 4875, "High-Accuracy Temperature Measurements Call for Platinum Resistance Temperature Detectors (PRTDs) and Precision Delta-Sigma ADCs."

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。

用系統調用signal()讓父進程捕捉鍵盤上來的中斷信號(按Ctrl-C鍵);當捕捉到中斷信號后,父進程用系統調用kill()向兩個子進程發出信號,子進程捕捉到信號后分別輸出下列信息后終止: Child Process 1 is Killed by Parent! Child Process 2 is Killed by Parent! 父進程等待兩個子進程終止后,輸出如下的信息后終止: Parent Process is Killed!

Quality, object.oriented architecture is the product of careful study, decision making, and experimentation. At a minimum, the object.oriented architecture process includes farming of requirements, architecture mining, and hands.on experience. Ideally, object.oriented architecture comprises a set of high.quality design decisions that provide benefits throughout the life cycle of the system.

Although there has been a lot of AVL tree libraries available now, nearly all of them are meant to work in the random access memory(RAM). Some of them do provide some mechanism for dumping the whole tree into a file and loading it back to the memory in order to make data in that tree persistent. It serves well when there s just small amount of data. When the tree is somewhat bigger, the dumping/loading process could take a lengthy time and makes your mission-critical program less efficient. How about an AVL tree that can directly use the disk for data storage ? If there s something like that, we won t need to read through the whole tree in order to pick up just a little bit imformation(a node), but read only the sectors that are neccssary for locating a certain node and the sectors in which that node lies. This is my initial motivation for writing a storage-media independent AVL Tree. However, as you step forth, you would find that it not only works fine with disks but also fine with memorys, too.
