Z1 CertServer (formerly Z1 Backbone Of Trust CertServer) is a server-based software solution for the storage and administration of X.509 certificates and OpenPGP keys. It targets customers who use a public key infrastructure (based on X.509 or OpenPGP) and who want to take advantage of the central access to certificates. It also automatically validates certificates by querying certificate revocation lists (CRLs) from the issuing trust centers, or by using OCSP (Online Certificate Status Protocol). Java and C/C++ SDKs are provided. It is available as pre-installed hardware or a virtual appliance, with evaluation packages for Debian and Solaris.
The STX ExecPipe library provides a convenient C++ interface to execute child programs connected via pipes. It is a front-end to the system calls fork(), pipe(), select(), and execv() and hides all the complexity of these low-level functions. It allows a program to build a sequence of connected children programs with the input and output of the pipe sequence redirected to a file, string, or file descriptor. The library also allows custom asynchronous data processing classes to be inserted into the pipe or placed at the source or sink of the sequence.
CS::SkipList Library is a C++ template library of containers based on skip lists. These containers work like sets and maps, but can also be accessed via numerical index. This collection has vector-like containers where all operations work in logarithmic time. It also has a composite container where you can order the same elements in many different ways at the same time.
The libQtCassandra library is an advanced C++ library used to access Cassandra servers. Unlike the basic Cassadra server interface, this C++ library provides separate objects that handle each level of the server data, i.e. the cluster, contexts, table, rows, and cells. It uses Qt and the Qt style for all the classes, which makes it very easy to use if you already know Qt.
libpetey is a small scientific/numerical computation library. It includes the following components: templated sorting routines; templated binary tree classes; a templated linked-list class; routines for finding the k-least and k-greatest elements in an array; "supernewton", a powerful one-dimensional root-finding algorithm that combines bracketing with fast, superlinear convergence; a class for working with dates and times; a templated sparse matrix class; datasets (the beginnings of a data-representation paradigm that generalizes matrices, which is mostly useful for easy linear interpolation, especially generalized, n-dimensional linear interpolation); a function for easy parsing of command line options; and command-line utilities for sparse matrix multiplication and eigenvalue decomposition.
