liblfds is a portable, lock-free data structure library. Out-of-the-box ports are provided for Linux (user-mode) and Windows (user-mode and kernel-mode) on ARM, x86, and x64, under a variety of toolchains. Currently, the library contains a freelist, queue, ringbuffer, singly-linked list (logical delete only), and a stack. The homepage contains a blog, bugzilla, forum, and mediawiki. The mediawiki contains comprehensive documentation for development, building, testing, and porting. There is no license. You are free to use this code in any way.
Biomechanical ToolKit (BTK) is a cross-platform library for biomechanical analysis. It can read and write a large variety of file formats used in biomechanics, and can modify them. All these operations can be done with the C++ API or with the wrappers included (Python, Octave, and Matlab). The goal of this project is to help the community share data without the restriction of the file format or the biomecanical model provided by the manufacturer of the acquisition system.
nan_payload is an Ada package that provides support for using the NaN payload field from IEEE-754 floating point. Storing 'non-available' errors as well as other symbolic values instead of any of the numbers in numeric arrays is necessary in many statistical applications. The package allows you to read and write the part of NaN IEEE754-64 bit values known as 'the payload', which is 51 bits long, and also to treat the long_float type as an implicit tagged type by storing tags and values in the payload. Calendar dates with ms resolution as well as 9-letter symbols and some not available/error codes are provided as subtypes. Formatted output with Fortran-like descriptors as well as reading values from strings for these types is also provided.
Zynaptic Reaction is a flexible asynchronous programming framework for Java which may be used to implement complex event-driven applications. It is heavily influenced by the Twisted programming framework developed by TwistedMatrix Labs for the Python programming language. The focus of the Reaction library is on the concurrency and callback model and as such it is application neutral. It can be used to manage lots of concurrent I/O or to farm out compute intensive tasks to multicore processors. As well as being usable as a basic Java library, Reaction can also run as an independent OSGi service and integrate into any GUI framework you choose.
Drumstick is a C++ wrapper around the ALSA library sequencer interface using Qt4 objects, idioms, and style. The ALSA sequencer provides software support for MIDI technology on Linux. Complementary multiplatform classes for SMF and WRK file processing are also included. This library is used in KMetronome, KMidimon, and KMid2 and was formerly known as "aseqmm".
