ZooKeeper is a centralized service for maintaining configuration information, naming, providing distributed synchronization, and providing group services. All of these kinds of services are used in some form or another by distributed applications. Each time they are implemented there is a lot of ... [More] work that goes into fixing the bugs and race conditions that are inevitable. Because of the difficulty of implementing these kinds of services, applications initially usually skimp on them ,which make them brittle in the presence of change and difficult to manage. Even when done correctly, different implementations of these services lead to management complexity when the applications are deployed. [Less]

refile is a file renamer which provide a new way to rename files, by concatenation of part which come from the old file, from fixed string or number generator NOT by just an insert, an append or modif. complex renaming can be done in only one pass.

libasyncns is a C library for Linux/Unix for executing name service queries asynchronously. It is an asynchronous wrapper around getaddrinfo(3), getnameinfo(3), res_query(3) and res_search(3) from libc and libresolv. In contrast to GNU's asynchronous name resolving API getaddrinfo_a(), libasyncns ... [More] does not make use of UNIX signals for reporting completion of name queries. Instead, the API exports a standard UNIX file descriptor which may be integerated cleanly into custom main loops. In contrast to asynchronous DNS resolving libraries like libdenise, skadns, adns, libasyncns is just an asynchronous wrapper around the libc's synchronous getaddrinfo() API, which has the advantage of allowing name resolution using techniques like Multicast DNS, LDAP or NIS using standard libc NSS (Name Service Switch) modules. libasyncns is compatible with IPv6 if the underlying libc is.
