The first persistent Web agent that we have created on Actor Prolog is a program that collects information about research groups that develop Prolog and projects in the field of logic programming. The agent looks through a given list of Web sites and calculates some attributes of the sites: the date of recent modification, total size, the number of figures, the number of outside links, the number of error links, the number of given keywords, etc. ... http://www.cplire.ru/Lab144/space/prolog.html . ...

... LWN.net FAQ . ... Read-copy-update (RCU) is a mutual exclusion technique which can operate without locking most of the time. It can yield significant performance benefits when the data to be protected is accessed via a pointer, is read frequently, changed rarely, and references to the structure are not held while a kernel thread sleeps. The core idea behind RCU is that, when the data requires updating, a pointer to a new structure containing the new data can be stored immediately. ...
