OpenAMQ is a fast, stable, free implementation of the AMQP (www.amqp.org) messaging protocol. It gives applications high-performance messaging (delivery of opaque data) across loosely connected networks. It is capable of handling up to 600k messages per second depending on the hardware, with a latency around 300 microseconds. It is multithreaded and supports C/C++ and Java on Linux, AIX, Solaris, OS/X, Windows, and OpenVMS.
Cybercluster is a multi-master replication solution. Cybercluster has no single point of failure, an integrated load balancer, an integrated replication server, a monitoring server (to track replication), a consistency checker, an optional 2 Phase Commit for cluster-wide writing, support for all PostgreSQL features. Cybercluster is easy to setup. In contrast to many other solutions, Cybercluster is built on top of the PostgreSQL core and has full access to PostgreSQL internals. Cybercluster is heavily based on the concepts of PGCluster.
Exscript is a scripting language for automating network connections over protocols such as Telnet or SSH. It is in some ways comparable to Expect, but has some unique features that make it a lot easier to use and understand for non-developers. It supports parallelization, logging, authentication mechanisms, and a lot more.
The Tcl Dev Kit (TDK) provides essential tools for Tcl programmers, making it easy to create, build, and deploy applications. You can rapidly deploy Tcl applications to a broad range of platforms as ready-to-run executables, starkits, or starpacks. Development is simplified with tools for finding and fixing bugs, managing complex code bases, and optimizing your programs. Take control and work the way you want with a choice of GUIs or command line interfaces for most tools.
GNU parallel is a shell tool for executing jobs in parallel locally or using remote computers. A job is typically a single command or a small script that has to be run for each of the lines in the input. The typical input is a list of files, a list of hosts, a list of users, a list of URLs, or a list of tables. If you use xargs today you will find GNU parallel very easy to use, as GNU parallel is written to have the same options as xargs. If you write loops in shell, you will find GNU parallel may be able to replace most of the loops and make them run faster by running several jobs in parallel. GNU parallel makes sure output from the commands is the same output as you would get had you run the commands sequentially. This makes it possible to use output from GNU parallel as input for other programs.
The Perl Dev Kit (PDK) provides essential tools for building and deploying Perl applications. PDK features cross-platform wrapping and application builders for various operating systems, plus a suite of tools to speed development time and improve code quality and consistency across teams.
Codehost's BrightQ is a suite of Unix and Linux printing utilities that presents users and administrators with a unified user interface across a variety of popular Unix printing systems, abstracting the details of print filters and providing a powerful GUI to end users. Extended printer features are also available for select printer manufacturers. BrightQ Pro also includes remote printer monitoring, network device detection, and more.
The MirBSD Korn Shell (mksh) is an actively developed successor of pdksh (the Public Domain Korn Shell), aimed at producing a shell good for interactive use, but with the primary focus on scripting. It is intended to be portable to most *nix-like operating systems as long as they're not too obscure. mksh incorporates improvements from OpenBSD and Debian, as well as bugfixes and enhancements developed for the MirOS, FreeWRT, and MidnightBSD projects and Android. The emacs command line editing mode is UTF-8 capable, and Byte Order Marks are ignored in scripts. The shell supports large files, as well as all pdksh and some csh, AT&T ksh, zsh, and GNU bash features, is compatible with the Bourne shell and POSIX (within limits), has no limit on array sizes, and incorporates some other useful builtins and features. While being already fast and small (without losing functionality), flags to make it even smaller can be given at compile time. An interactive shell reads "~/.mkshrc" on startup.
