pgpool is a connection pool server for PostgreSQL. pgpool runs between PostgreSQL's clients (front ends) and servers (back ends). A PostgreSQL client can connect to pgpool as if it were a standard PostgreSQL server. pgpool caches the connection to a PostgreSQL server to reduce the overhead to establish the connection to it. Also, pgpool can use two PostgreSQL servers for fail over. If the first server goes down, pgpool will automatically switch to the secondary server. Moreover, pgpool supports scheduled switch over.
darcspublish is a shell script that allows you to easily share your Darcs repository between different computers, give read access to the world, or publish a Web site that is backed by a Darcs repository on your computer. It should work with any Bourne shell, and only needs Darcs and sitecopy to work.
MPIBZIP2 is a parallel implementation of the bzip2 block-sorting file compressor that uses MPI and achieves significant speedup on cluster machines. The output of this version is fully compatible with bzip2 1.0.2 or newer (i.e. anything compressed with MPIBZIP2 can be decompressed with bzip2).
OpenFWTK is an application proxy toolkit which inherits the ideology of TIS fwtk and maintains API backwards compatibility. The design goal is to make it simple yet powerful; no performance hacks are allowed in the code and library dependencies are reduced to a minimum. It is a true application layer filter. It features unified pluggable content inspection for the most frequently used protocols, NAC (Network Admission Control), and the ability to define fine-grained Internet access policy based on browser identification.
Template based B+ Tree is a simple and yet very efficient template based B+ Tree implementation which supports different types of storage. It is implemented in C++, and can be used with any type of data. To change storage type (e.g. from file based to memory based), all you need is to change a template argument of the BTreeAlgorithms class. Either the standard search method or a customized search method can be used.
MorkParser is an efficient C++ implementation of a Mork database format reader. The Mork format is used in most Mozilla-based projects, including the Mozilla browser suite, SeaMonkey, Firefox, and Thunderbird. In Firefox, it is used for browsing history data and form history data. In Thunderbird, it is used for many things, such as address book data (.mab files) and the mail folder summaries (.msf files). The MorkParser class uses Qt, therefore it is cross-platform.
