The Logfile Navigator, lnav for short, is a curses-based tool for viewing and analyzing log files. The value added by lnav over text viewers or editors is that it takes advantage of any semantic information that can be gleaned from the log file, such as timestamps and log levels. Using this extra semantic information, lnav can do things like interleaving messages from different files, generate histograms of messages over time, and provide hotkeys for navigating through the file. These features are meant to allow the user to quickly and efficiently focus on problems.
Proelia is a multi-game system encounter tracker for pen-and-paper RPGs. It allows you to create "prepared" encounters for later use, and then run them any number of times with the click of a button. A group can be created from an encounter's participants, and then re-used in other encounters. Each encounter can display a map that allows you to track positioning of participants, especially in relation to regions, so you can tell if someone is standing too close to a fire, or is subject to an aura or other environmental effect. A color and marker text can be set for each participant in the encounter, so you can quickly find them on the map. A variety of RPGs are supported through a plugin system that allows new systems to be added.
Wisecracker is a high performance distributed cryptanalysis framework that leverages GPUs and multiple CPUs. It allows security researchers to write their own cryptanalysis tools that can distribute brute-force cryptanalysis work across multiple systems with multiple multi-core processors and GPUs. Security researchers can also use the sample tools provided out-of-the-box. The differentiating aspect of Wisecracker is that it uses OpenCL and MPI together to distribute the work across multiple systems, each having multiple CPUs and/or GPUs.
