ProtoMol is an object-oriented, component based, framework for molecular dynamics (MD) simulations. The framework supports the CHARMM 19 and 28a2 force fields and is able to process PDB, PSF, XYZ and DCD trajectory files. It is designed for high flexibility, easy extendibility and maintenance, and high performance demands, including parallelization. The technique of multiple time-stepping is used to improve long-term efficiency. The use of fast electrostatic force evaluation algorithms like Ewald, particle Mesh Ewald (PME), and Multigrid (MG) summation further enhances performance. Longer time steps are possible using MOLLY, Langevin Molly and Hybrid Monte Carlo, Nose-Hoover, and Langevin integrators. In addition, ProtoMol has been designed to interact with VMD, a visualization engine developed by the University of Illinois that is used for displaying large biomolecular systems in three dimensions. ProtoMol is freely distributed software, and the source code is available.

BRL-CAD is a powerful Combinatorial/Constructive Solid Geometry (CSG) solid modeling system that includes an interactive geometry editor, ray-tracing support for rendering and geometric analysis, network-distributed framebuffer support, image and signal-processing tools, and an embedded scripting language. The package is a collection of over 400 tools and utilities across over 750,000 lines of source code. Included is support for various geometric data format conversions, image and signal processing capabilities, sophisticated ray-tracing based lighting models, network distributed ray-tracing, massively parallel ray-tracing, animation capabilities, data compression, image handling, and interactive 3-D geometric editing. Included is an implementation of Weiler's n-Manifold Geometry (NMG) data structures for surface-based solid models and photon mapping.

A Three-Dimensional Structural Finite Element Program CalculiX Finite Element Models can be build, calculated and post-processed. The pre- and post-processor is an interactive 3D-tool using the openGL API. Notice: The authors acknowledge that naming conventions and input style formats for CalculiX are based on those used by ABAQUS, a proprietary, general purpose finite element code developed and supported by Hibbitt, Karlsson & Sorensen, Inc (HKS) and are used with kind permission from HKS. Results obtained from CalculiX are in no way connected to ABAQUS. note: By default the single-threaded solver is used, this can be changed by setting the OMP_NUM_THREADS environment variable with the number of processors you want to use.

This is Gmsh with support of OpenCascade. Gmsh is an automatic 3D finite element mesh generator (primarily Delaunay) with build-in CAD and post-processing facilities. Its primal design goal is to provide a simple meshing tool for academic test cases with parametric input and up to date visualization capabilities. One of its strengths is the ability to respect a characteristic length field for the generation of adapted meshes on lines, surfaces and volumes, and to mix these meshes with simple structured grids. Gmsh is built around four modules: geometry, mesh, solver and post-processing. The specification of any input to these modules is done either interactively using the graphical user interface or in ASCII text files using Gmsh's own scripting language.

Logisim is an educational tool for designing and simulating digital logic circuits. With its simple toolbar interface and simulation of circuits as you build them, it is simple enough to facilitate learning the most basic concepts related to logic circuits. With the capacity to build larger circuits from smaller subcircuits, and to draw bundles of wires with a single mouse drag, Logisim can be used (and is used) to design and simulate entire CPUs for educational purposes. Logisim is used by students at colleges and universities around the world in many types of classes, ranging from a brief unit on logic in general-education computer science surveys, to computer organization courses, to full-semester courses on computer architecture.

A True Type Font Manager that handles true type font installation, uninstallation, list, and default font setting. It was originally in the CLE distribution. The manager doesn't deal with applications using TTF directly. Instead, it calls modules to handle the details. There are only several predefined behaviours of the modules, like add/remove/list. There are four modules as of version 0.9: chitex: For ChiTeX, a Chinese TeX/LaTeX ttf2pk: Generate pk/tfm for CJK xfreetype: For Xfsft in XFree86 3.3.x and "freetype" module in 4.x xttfm: For X-TT in XFree86 3.3.x and "xtt" module in 4.x, avaiable in both tcl and sh versions. Some modules are Big5/GB enhanced, for better font detection/generation.

Dump 1090 is a Mode S decoder specifically designed for RTLSDR devices. The main features are: * Robust decoding of weak messages. * Network support: TCP30003 stream (MSG5...), Raw packets, HTTP. * Embedded HTTP server that displays the currently detected aircrafts on Google Map. * Single bit errors correction using the 24 bit CRC. * Ability to decode DF11, DF17 messages. * Ability to decode DF formats like DF0, DF4, DF5, DF16, DF20 and DF21 where the checksum is xored with the ICAO address by brute forcing the checksum field using recently seen ICAO addresses. * Decode raw IQ samples from file (using --ifile command line switch). * Interactive command-line-interfae mode where aircrafts currently detected are shown as a list refreshing as more data arrives. * CPR coordinates decoding and track calculation from velocity. * TCP server streaming and receiving raw data to/from connected clients.

The Arduino Uno (http://arduino.cc/) is an open source hardware micro- controller designed primarily for prototyping and experimentation. Although the devel/arduino port already exists for programming the device, it will not work properly with the newest Arduino hardware. Previous versions of the Arduino used an FTDI USB to Serial interface. The newest Arduino (beginning with the Uno) uses an on-board ATMel 8U2 controller to emulate a USB to Serial interface with its own custom Vendor ID and Hardware ID. As a result, NONE of the existing FreeBSD USB to serial drivers can work with it. This kernel driver supplies the necessary kernel support for the Arduino Uno on FreeBSD. Additionally, some 'ACM' USB Serial devices may work with this driver by manually adding their Vendor ID and Product ID combination to files/ids.txt Official web site

This is a driver for "homebrew" type serial LIRC reveivers as described here: http://lirc.org/receivers.html It overrides the `normal' uart(4) driver, if you have that driver already loaded or statically in your kernel (like it is in GENERIC) then you need to load uartlirc.ko from loader.conf(5) (or manually via the loader prompt) for the override to work. The driver provides a /dev/lircX node for each serial port in addition to the normal tty nodes /dev/cuauX etc, so you can still use other serial ports normally should you have more than one. Note: it only supports PCI/motherboard serial ports not ones connected via USB, for USB you can use mceusb hardware supported via webcamd, or FTDI hardware supported by comms/lirc natively via libftdi, see: http://wiki.freebsd.org/WebcamCompat and the comms/lirc port's pkg-message.
