hwloc provides command line tools and a C API to obtain the hierarchical map of key computing elements, such as: NUMA memory nodes, shared caches, processor sockets, processor cores, and processor "threads". hwloc also gathers various attributes such as cache and memory information, and is portable across a variety of different operating systems and platforms. hwloc primarily aims at helping high-performance computing (HPC) applications, but is also applicable to any project seeking to exploit code and/or data locality on modern computing platforms.
filter_evdev creates a virtual input device from a physical input device. It provides anytime configuration of positive, negative, or custom acceleration or sensitivity for each axis, or remapping axes or buttons as requested, e.g. inverting the two main mouse buttons or making the middle button act as the right button. Configuration can be dynamically changed by text commands sent to a UNIX socket. Commands apply to specific axes, buttons, or keys when moved in specified value ranges, and consist of custom arithmetic operations.
Ejecter is a little tool that makes it possible to unmount external devices and eject CD-ROMs without having to right-click on the device icon (either on the desktop or in Nautilus). It sits in the background and shows an icon in the system tray when one or more peripherals are connected to your PC: once clicked, a window appears with the list of the devices (volume name and device type, and much clearer than the similar thing available on Windows) and the related eject button. Being written in Vala, it is translated into C code and then compiled. This means that it's lightweight and consumes little memory, does not require a full VM like Python, and has no strange requirements to run (just GLib/GTK).
Likwid is a set of easy to use command line tools for Linux. It supports programmers in developing high performance multi-threaded programs. "Likwid" stands for "Like I knew what I am doing". It contains the following tools: likwid-topology, which shows thread and cache topology; likwid-perfctr, which measures hardware performance counters on Intel and AMD processors; likwid-features, which shows and toggles hardware prefetch control bits on Intel Core 2 processors; likwid-pin, which pins a threaded application without touching its code (it supports pthreads, Intel OpenMP, and gcc OpenMP), likwid-powermeter which prints the Turbo mode steps and measures energy consumption on supported Intel processors, and likwid-bench, a low level benchmarking framework. It works with any standard Linux kernel. Likwid is lightweight and adds no overhead during measurements.
OpenSCB is a hardware and software solution for controlling servos over USB. The hardware is designed to interface with classic RC servos, AX-12/AX-18 servos, OpenServo, and more using a powerful 32-bit microcontroller with a USB port for programming and control with a PC. The schematic and layout will be available and can be customized. A graphical interface is also provided for your computer to configure, calibrate, and control the board.
Leevi is a user interface for the Lexicon MX300 reverberation device (and possibly other MX devices). It is similar to what Lexicon ships along with their devices for Windows operating systems. Leevi works with POSIX compatible operating environments, like Linux, FreeBSD, NetBSD, OpenBSD, and so on.
hwmultd is a daemon which, when run in server mode, periodically polls some hardware device, like an entropy source, and multicasts that information. Alternatively, hwmultd can run in client mode, listening for multicasted information and then acting accordingly, like adding gathered entropy to the local pool. Its simple plugin system allows hwmultd to be agnostic with respect to the hardware, which could include devices such as temperature probes or time sources.
