Video Projector/Monitor Calibration Software orginally developed as ColorHCFR. This code base is based off version 2.1 and will aim for a more open development process. The opensource version integrates an ArgyllCMS interface for continued meter support and development. If you feel the program has been of value to you since I started working on it about 3 years ago please consider a contribution via the link below. Thanks! -zoyd https://www.paypal.me/zoyd

Darling is a free and open source runtime compatibility layer—akin to Wine—for Linux that allows native macOS (Darwin) applications to run directly without hardware emulation. It implements macOS libraries and frameworks, enabling macOS binaries to execute on Linux. Darling has support for DPREFIXes, which are very similar to WINEPREFIXes. They are virtual “chroot” environments with an macOS-like filesystem structure, where you can install software safely. The default DPREFIX location is ~/.darling, but this can be changed by exporting an identically named environment variable. A prefix is automatically created and initialized on first use. Please note that we use overlayfs for creating prefixes, and so we cannot support putting prefix on a filesystem like NFS or eCryptfs. In particular, the default prefix location won't work if you have an encrypted home directory.

Lynkeos is a Cocoa® application dedicated to the processing of astronomical digital images taken through a telescope. It is optimized for SSE vectorized instructions sets, multi-processor and multi-core machines.

A native Macintosh front-end and distribution for the GAP computer algebra system. It provides a Mac-like command editing environment and save/load, while making available graphical libraries compatible with xgap.

A multiplatform C++ library for dynamic generation of Excel .xls files containing multiple worksheets. Unlike .csv files, these can be directly opened by Excel and thus provide an excellent way to output large data sets that require further analysis. To see the latest changes, select "Files" and view the README text displayed at the bottom of that pane. IMPORTANT: Major changes are contained in the current SVN source. If you have time please try to use it or the xlslib-package-2.4.0b1.zip archive, and enter bug reports on any problems! Changes: - library specific strings now in their own namespace - iOS Objective-C library - most project files updated (MSVS etc) - C bridge now supports formulas Note: there is a related SF project, libxls, to read Excel files.

FastEasyMapping is a lightweight and high-performance framework designed for mapping JSON or other data formats into native Objective-C objects on iOS. It simplifies the process of converting raw data into models and is built with a focus on speed and efficiency, making it suitable for apps dealing with large datasets or frequent network responses.

N.B. SuperCollider is now hosted at GitHub, and the most recent versions can be downloaded from there. http://supercollider.github.io A real time audio synthesis engine, and an object-oriented programming language specialised for music. SuperCollider was created in 1996 by James McCartney, now (since version 3) released as free software.

DarwiinRemote is a tiny program & library which reads data from and sends data to Nintendo Wii Remote (Wiimote), nunchuk, & classic controller.

The project has moved to GitHub: https://github.com/pixmeo/osirix

TaskBoard brings the simplicity of iOS to your Mac. Access all your running tasks with simple keystroke combinations and with a five fingers multitouch gesture. TaskBoard is specially useful when you are using many fullscreen apps at the same time. Swap between active tasks or kill tasks with a single click. New on Beta 0.44 - Global multitouch gesture; - Main performance issues fixed; - Preview option removed; - Scrollbars display fixed; - Monitor app performance issues fixed; - Mouse gesture removed. New on Beta 0.44.1 - Multilingual Application identification issue fixed; New on Beta 0.5.1 - New System Preferences Pane; - Vertical and Horizontal tray style; System Requirements: -OS X 10.8 or later;

MatrixGen is a Bioinformatics application used to generate scoring matrices from analysis of aligned Amino Acid and DNA data sets. These matrices can then be used by Clustal to generate more accurate alignments. Based upon the Henikoff BLOSUM method.

Baculator is a Reverse Polish Notation (RPN) calculator program with an infinite scrollable stack and support for most common mathematical operations as well as some more esoteric operations. Available for Unix/Gtk+, Mac OS X, and MS Windows.

The purpose of the CoCalc project is to develop a simple RPN calculator application for use on laptops running OS X. It has been developed in Cocoa and Objective C, although it may change to a PyObjC application in the future.

If you are looking for the 64-bit version, find it here: http://sourceforge.net/projects/gjsieve/files/200/gjsieve203.exe/download GJSieve is a basic, yet full-featured sieve and tester for numbers of several classifications, including Proth, Cullen, and Woodall. GJSieve is built on the GNU Multiple-Precision (GMP) integer + rational library, and is available for both Windows and OSX. Currently, the application differs greatly across platforms. This may change in the future. They both, however, do the same thing.

HubbleView is a monitor calibration program that converts Yxy samples received from the Xrite Hubble to D65 and displays them on an RGB bar graph. HubbleView is helpful for setting white balance on broadcast monitors and projectors.

The 'LPT Interface' application is great for students. With 'LPT Interface' pupils can write & read the parallel port's: Data Port (8 bit), Control Port (4 bit) and read Status Port (4 bits).

RSM (Radiation Spectrum Method) is a 2D rigorous tool to solve the Maxwell equations for the propagation of light in integrated optics or photonics devices. It makes use of an EigenMode Expansion method (EME) to solve the electromagnetic problem. This software running on Windows and MacOS comes with a GUI that permits to define with the aid of files or scripts the arbitrary and complex geometry of the waveguide. Of that way any waveguide geometry can be handled. Several plots are available : refractive index plot, field propagation plot and modes spectrum plot. This permits, with the interpretation of the guided and radiation modes spectrum, a physical understanding of the propagation mechanisms in the integrated optical device under evaluation. The complex geometry of the component is discretized in a stack of multilayer dielectric waveguides. For Windows, download "RSM_visit_update2.zip" , this file needs the last version of the software be first installed : "RSM VisitSetup2.ex

Wii joystick interface. Wiiji is the perfect joystick solution for Wii remotes on Mac. Wii remotes will appear as joysticks to the OS. It does this through a kernel extention. It can emulate keyboard input. It runs in the menu bar.

6Vertex is an Objective C/Cocoa application (and standard C functions) for computing and visualizing matrix models generated with the 6-vertex model for computing boundary shapes and phase transition shapes for differently weighted vertices.

Aircraft navigation receiver using software-defined radio (SDR)

ArchiScale is an easy-to-use Mac OS X software that converts distances using a user-defined scale. It is also able to determine which scale is the best to draw something on a given paper format. This software is useful for students in first years of architecture schools, when you work without CAD-softwares, and for people using non-numerised documents with uncommon scales.
