gnhast is a collection of daemons that work together to build an event-based home automation system. Any event (such as a light being turned on) can be handled by an external script or program. These programs can be written in any language, and the central daemon handles all the intercommunication. It is designed to be easily extensible for new device types and protocols.
PerfMonger is an yet another performance monitoring tool. The monitoring targets of PerfMonger are similar to the ones of sysstat (CPU usages, IO usages, etc.), but PerfMonger can collect and report performance information very frequently (the reporting interval of sysstat is 1 second at minimum, but PerfMonger can use a much smaller interval such as 0.5 seconds or 0.01 seconds) and can display performance information in both human-readable and machine-readable formats.
Univention Corporate Client (UCC) is a flexible and efficiently manageable operating system for PCs, notebooks, and thin clients in companies and institutions. The software contains a Linux-based desktop environment optimised for business use. It allows desktops to be adapted to hardware and intended application. In addition, it can be managed conveniently and efficiently via a Web-based console. In comparison to other systems, it guarantees integrated administration procedures for users, clients, desktops, and permissions and effectively does away with the use of different, uncoordinated tools. It serves as a platform for access to remote desktop solutions and virtualized desktops as well as browser or terminal server-based applications.
nrun is a tool that runs a single command or script on multiple target servers synchronously. ncopy will copy a file or directory to multiple target servers. The underlying remote access mechanism is interchangeable, and currently supports ssh, nsh, rsh, and local execution modes. The return code and all command output is logged.
ZedLog is a robust cross-platform input logging tool (A.K.A., a key logger). It is based on a flexible data logging system which makes it easy to get the required data. It features logging of all keyboard and mouse events, a replay simulation tool, logging to a file, and hiding in the background.
QMentat helps you practice mental arithmetic. It uses arbitrary-length fixed point arithmetic, and can handle any size numbers, only limited by the size of your screen (and in the case of division with an integer result, the speed at which the number can be factored). It is also quite configurable, allowing you to tailor the questions to your needs.
Megatools is a collection of programs for accessing the Mega service from the commandline of your desktop or server. It allows you to copy individual files as well as entire directory trees to and from the cloud. You can also perform streaming downloads (for example, to preview videos and audio files) without needing to download the entire file. The tools are robust and optimized for fast operation, as fast as the Mega servers allow. Memory requirements and CPU utilization are kept at minimum. You can register an account using a "megareg" tool, with the benefit of having true control of your encryption keys.
