Monkey HTTP Daemon is a very fast and lightweight Web server for Linux. It uses a hybrid networking model based on asynchronous calls (event-driven) and fixed threads, which makes it scalable and capable of attending thousands of clients per second. It provides a powerful API for C and is ideal for embedded devices, thanks to its small core and plugin architecture.
Bastille Unix (formerly Bastille Linux) aims to be the most comprehensive, flexible, and educational Security Hardening Program for Red Hat (Fedora Core, Enterprise Linux, and original Red Hat), SuSE, Gentoo, Mandrake, and Debian Linux, as well as HP-UX and Mac OS X. Virtually every task it performs is optional, providing immense flexibility. It educates the installing admin regarding the topic at hand before asking any question. The interactive nature allows the program to be more thorough when securing, while the educational component produces an admin who is less likely to compromise the increased security.
Catdoc is a MS Word file decoding tool that doesn't attempt to analyze file formatting (it just extracts readable text), but is able to handle all versions of Word and convert character encodings. A Tcl/Tk graphical viewer is also included. It can also read RTF files and convert Excel and PowerPoint files.
VoiceOne is a Linux distribution that gives you the ability to install a PBX platform with an easy to use Web-based GUI. It also provides a framework for building a communication server adding various plugins. Its main features are Asterisk 1.8 with realtime configuration with MySQL, a Ubuntu 10.04 base, and support for both hard disk and Compact Flash card installation.
Kpl is a KDE program for two- and three-dimensional graphical presentation of data sets and functions (plotter). Multidimensional nonlinear parameter fits of functions to data sets can be performed using the Levenberg-Marquardt algorithm. General linear least square parameter fits are also possible. A D-BUS interface can be used to control Kpl by other applications and scripts.
comedirecord is an oscilloscope program to record data from a COMEDI-compatible device. Its philosophy is to save the data in its original unfiltered form but allow comfortable viewing of the data during an experiment. One can acquire data from multiple DAQ boards simultaneously, and also append data via an incoming TCP port, which could be a telnet connection into comedirecord or data from another program. Low-pass, high-pass, and notch filters can be switched on for each channel. A DC filter can be switched on, which is useful when observing small voltage changes at a high gain (for example, measuring small temperature changes). The output format is ASCII so that the data can be imported into GNUPLOT, scilab, or octave.
TeXstudio is a fully featured LaTeX editor. It is designed to make writing LaTeX documents as easy and comfortable as possible. It features an integrated PDF viewer with (almost) word-level synchronization, live inline preview, advanced syntax highlighting, and live checking of references, citations, LaTeX commands, spelling, and grammar.
Liberté Linux is a secure, reliable, lightweight, and easy to use Gentoo-based live USB Linux distribution intended as a communication aid in hostile environments. It installs as a regular directory on a USB/SD key, and after a single-click setup, boots on any desktop computer or laptop. The Internet connection is then used to set up a Tor circuit, which handles all network communication. During first boot, a unique email ID is generated from fingerprints of user's certificate and Tor hidden service key. This persistent ID allows one to stealthily communicate with other Liberté users. The distribution includes image and document processing applications, and can function as a secure Web browsing platform. For developers, Liberté can also serve as a robust framework for mastering Gentoo-based live USBs/CDs. The build process is fully automated with incremental build support, and is more mature and reliable than most of Gentoo's own outdated live CD tools.
Hados stores files in a cluster of servers. Its goal is to handle high availability by storing copies of the same file on several nodes. It provides RESTFUL APIs to easily store, check, or retrieve files. Using the cluster APIs, you can retrieve files from whichever node hosts them. To avoid any single point of failure, it is possible to apply a request to any node of the cluster; there is no master node.
