This is the Python extension to usbrelay, a Linux driver based on hidapi for a variety of inexpensive HID compatible USB relay modules. This package also includes usbrelayd.

Hardware Probe is a tool to probe for hardware, check its operability and find drivers.

OpenHMD aims to provide an API and drivers for immersive technology, such as head mounted displays with built in head tracking.

Memtester stress-tests the memory subsystem of your operating system and computer. It repeatedly writes different patterns to all memory locations, reads them back again, and verifies whether the result is the same as what was written. This can help debug even intermittent and non-deterministic errors.

Memtester runs entirely in user space. This means that you don't need to reboot to test your memory, but also that it's not possible to test all of the RAM installed in the system.

It can also be told to test memory starting at a particular physical address.

ddcui is a graphical user interface for ddcutil, implemented using Qt. It provide a dynamic way to inspect and configure external monitors through the Display Data Channel Command Interface (DDC/CI) protocol.
